Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences."

            "abstract_text": "ID: 41195425\nTitle: Guidelines for diagnosis and treatment in neurology - Lyme neuroborreliosis.\nAbstract: Lyme disease is the most common tick-borne infectious disease in Europe. Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor. Im Rahmen eines systematischen Reviews zur Therapie des sogenannten Post-Treatment Lyme Disease Syndrome (PTLDS) zeigte sich, dass die untersuchten Parameter Lebensqualit\u00e4t, Fatigue, Depression und Kognition nicht auf eine antibiotische Therapie ansprechen. F\u00fcr die Wirksamkeit anderer Therapieverfahren fanden sich keine aussagekr\u00e4ftigen Studien."

The aim of this exploratory study was to evaluate the feasibility of protein biomarker profiling as a diagnostic platform for this category of patients and to compare these results with similarly obtained results from a group of patients with acute neuroborreliosis. Two groups of patient cohorts (Cohort 1 and 2) were analyzed for biomarkers in serum and cerebrospinal fluid (CSF); the results were used for group-level comparison. Cohort 1 comprised 158 adult patients selected from 224 previously diagnosed patients, who between October 2015 and December 2018, after referral, were enrolled and structurally investigated based on defined inclusion criteria. They displayed similar lingering symptoms, with a duration of at least 6 months, after presumed previous tick-borne infection (TBI) and are fully described in a previously published study originating from the Center for Vector-borne Infections (CVI), Uppsala University Hospital, Sweden. Cohort 2, comprised 30 patients diagnosed at Uppsala University Hospital between 2016 and 2019 with laboratory-confirmed acute neuroborreliosis. Their proteomic results, based on serum and CSF analyses, were compared with the 158 patients in Cohort 1. The expression and the concentration of potential biomarkers in each patient's serum and CSF samples were measured based on two multiplex protein panels enabling simultaneous analysis of 92 inflammatory and neurology biomarkers. The PTLDS patient subgroup showed no nominally significant proteins compared to the other CVI patients in Cohort 1. However, CVI patients with signs of inflammation, which were evenly distributed in Cohort 1, showed 16 significantly (p <0.05) different proteins in both CSF and serum, but no association was seen with laboratory-confirmed exposure to Borrelia spp or other TBIs. When comparing the two cohorts, different protein profiles were observed, with 125/148 significantly different proteins in CSF and 93/174 in serum, in patients with laboratory confirmed acute neuroborreliosis, of which 6 in CSF and 6 in serum were significant at the p <0.001 level. In this first comprehensive inflammatory and neurological biomarker profile study no differences in biomarker profiles were detected between patients with PTLDS and patients with similar persisting symptoms but who did not meet the PTLDS criteria, regardless of whether laboratory verified previous exposure to Borrelia or other TBI's were present. However, the expressed markers differed from those found in patients with confirmed acute neuroborreliosis, which does not support the view that PTLDS reflects an ongoing Borrelia infection. Further studies are needed to understand and assess the usefulness of biosignatures of patients with PTLDS before they can be applied in a clinical setting."

Persisting symptoms are often termed post-Lyme disease syndrome, of which etiology is not clearly understood. The aim of this study was to investigate cognitive function, possible structural changes in brain regions and level of fatigue. We have not found previous studies on neuroborreliosis that use standardized neuropsychological tests and MRI with advanced image processing to investigate if there are subtle regional changes in cortical thickness and brain volumes after treatment. We examined 68 patients treated for neuroborreliosis 6\u00a0months earlier and 66 healthy controls, with a comprehensive neuropsychological test protocol, quantitative structural MRI analysis of the brain and Fatigue Severity Scale. We found no differences between the groups in either cognitive function, cortical thickness or brain volumes. The patients had higher score on Fatigue Severity Scale 3.8 vs. 2.9 (p\u2009=\u20090.001), and more patients (25.4%) than controls (5%) had severe fatigue (p\u2009=\u20090.002), but neither mean score nor proportion of patients with severe fatigue differed from findings in the general Norwegian population. The prognosis regarding cognitive function, brain MRI findings and fatigue after adequately treated neuroborreliosis is favorable."

PTLDS (post treatment Lyme disease syndrome) is a controversial topic. It has been described as a source of overdiagnosis and off-label treatment. This review aims to describe the diagnostic errors and adverse events associated with the diagnosis and treatment of PTLDS. systematic review of the literature in the Medline and Cochrane Library databases, according to PRISMA criteria, including randomized clinical trials (RCT), observational studies, and case reports addressing diagnostic errors and adverse events published between January 2010 and November 2020 in English or French. Selection used a quadruple reading process on the basis of the titles and abstracts of the different articles, followed by a full reading. 17 studies were included: 1 RCT, 6 observational studies and 10 case reports. In the 6 observational studies, overdiagnosis rates were very high, ranging from 80 to 100%. The new diagnoses were often psychiatric, rheumatological and neurological. Disorders with somatic symptoms were often cited. Diagnostic delays were identified for cancers and frontoparietal dementia. In the RCT and observational studies, prolonged anti-infective treatments were also responsible for adverse events, with emergency room visits and/or hospitalization. The most common adverse events were diarrhea, sometimes with Clostridium difficile colitis, electrolyte abnormalities, sepsis, bacterial and fungal infections, and anaphylactic reactions. This review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS. It emphasizes the ethical imperative of the \"primum non nocere\" principle, which underscores the importance of not causing harm to patients. Physicians should exercise caution in diagnosing PTLDS and consider the potential risks associated with off-label treatments."

To guide treatment recommendations, a systematic review was performed of the available literature on specific treatment for PTLDs. A systematic literature search of MEDLINE and CENTRAL was performed. No restrictions on case definitions, study types or specific interventions were applied to enable a comprehensive overview of the available literature. Risk of bias was assessed using the Cochrane risk of bias tools for randomized controlled trials. Certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach. Outcomes of interest were quality of life, fatigue, depression and cognition as well as adverse events. After screening 1274 records, eight eligible randomized controlled trials were included. Heterogeneity was observed regarding inclusion criteria, intervention, length of treatment and outcome measures. For efficacy outcomes, results are presented narratively due to heterogeneity. Eligible studies show no statistically significant difference between antibiotics and placebo regarding quality of life, cognition and depression. Results for fatigue were inconsistent whilst studies with low risk of bias showed no statistically significant difference between antibiotics and placebo. Meta-analysis of safety outcomes showed statistically significantly more adverse events for antibiotics compared to placebo. Available literature on treatment of PTLDs is heterogeneous, but overall shows evidence of no effect of antibiotics regarding quality of life, depression, cognition and fatigue whilst showing more adverse events. Patients with suspected PTLDs should not be treated with antibiotics."

These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues."

There is currently no specific treatment for this condition. The subjects were divided into two groups: one group received 150 mg/day of Pycnogenol\u00ae alongside standard management, while the control group received only standard management. The observation period lasted for six months. Forty subjects with history of Lyme Disease and persistent symptoms completed the study: 20 in the Pycnogenol\u00ae group, 20 in the control group. No side effects from the supplementation were observed. The tolerability was optimal as no supplemented subject had to stop management and compliance was optimal with 97% of the Pycnogenol\u00ae capsules correctly used. The two groups were comparable for sex, age distribution and for their main clinical findings and signs/symptoms at inclusion. During the study, corticosteroids at low dose were used on demand in 10% of subjects using Pycnogenol\u00ae and significantly more, in 45% of the control patients (P<0.05). After 6 months, the number of patients experiencing symptoms was significantly lower in the Pycnogenol\u00ae group compared to the control group across all symptoms (P<0.05). After 6 months, the intensity of all symptoms in the Pycnogenol\u00ae group, was significantly lower, according to the scores in comparison with the control group (P<0.05). Plasma oxidative stress was significantly reduced in subjects of the Pycnogenol\u00ae group (P<0.05) in comparison with controls. The improvement in plasma oxidative stress was seen in all subjects using Pycnogenol\u00ae. Knee effusion on ultrasound was seen in 12 subjects of the supplement group at inclusion and in 3 Pycnogenol\u00ae subjects at the end of the study in comparison with 12/20 subjects in the control group at inclusion and 8/20 at the end of the study. (P<0.05). Finally, ESR (Erythrocyte sedimentation rate, a global marker of inflammation) was significantly more reduced in the Pycnogenol\u00ae group by the end of the study compared to controls (P<0.05). In conclusion, the present registry study showed that Pycnogenol\u00ae intake for 6 months in patients with persistent symptoms of Lyme disease can help relieve the main symptoms by reducing inflammation and oxidative stress. Pycnogenol's anti-inflammatory and antioxidant double activity may help safely and effectively controlling the chronic inflammatory process."

Here, we evaluated in silico the predicted binding affinities of 192 HLA-II alleles with all 15-mer peptide sequences of five Borrelia burgdorferi proteins to identify peptides with strong binding affinity, as they would be the best candidates for antibody production in response to vaccination. We found the following: (a) 226 of the 1067 peptides tested (21.2%) were found to bind strongly to HLA-II molecules; (b) decorin-binding protein A had the greatest number of strongly binding peptides; and (c) 69 HLA-II alleles (primarily of the DRB1 gene) bound with strong affinity to peptides from Borrelia burgdorferi proteins. Finally, we tested for possible susceptibility to autoimmunity by any one of the 226 peptides above by searching for their occurrence in ~84,000 proteins of the human proteome and found overlap with only two 8-mer peptide sequences (embedded within the 226 15-mer peptides), neither of which was characterized by strong binding to HLA-I, suggesting a reduced likelihood of autoimmunity. These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety. The results of this computational study provide novel directions for future development of Lyme vaccines."

This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination."

Brain PET scan of patients with PTLDS have demonstrated likely glial activation indicating persistent neuroinflammatory processes. It is possible that unresolved bacterial remnants can continue to cause neuroinflammation. In previous studies, we have shown that non-viable Borrelia burgdorferi can induce neuroinflammation and apoptosis in an oligodendrocyte cell line. In this follow-up study, we analyze the effect of sonicated remnants of B. burgdorferi on primary rhesus frontal cortex (FC) and dorsal root ganglion (DRG) explants. Five FC and three DRG tissue fragments from rhesus macaques were exposed to sonicated B. burgdorferi and analyzed for 26 inflammatory mediators. Live bacteria and medium alone served as positive and negative control, respectively. Tissues were also analyzed for cell types mediating inflammation and overall apoptotic changes. Non-viable B. burgdorferi induced significant levels of several inflammatory mediators in both FC and DRG, similar to live bacteria. However, the levels induced by non-viable B. burgdorferi was often (several fold) higher than those induced by live ones, especially for IL-6, CXCL8 and CCL2. This effect was also more profound in the FC than in the DRG. Although the levels often differed, both live and dead fragments induced the same mediators, with significant overlap between FC and DRG. In the FC, immunohistochemical staining for several inflammatory mediators showed the presence of multiple mediators in astrocytes, followed by microglia and oligodendrocytes, in response to bacterial remnants. Staining was also seen in endothelial cells. In the DRG, chemokine/cytokine staining was predominantly seen in S100 positive (glial) cells. B. burgdorferi remnants also induced significant levels of apoptosis in both the FC and DRG. Apoptosis was confined to S100\u2009+\u2009cells in the DRG while distinct neuronal apoptosis was also detected in most FC tissues in response to sonicated bacteria. Non-viable B. burgdorferi can continue to be neuropathogenic to both CNS and PNS tissues with effects likely more profound in the former. Persistence of remnant-induced neuroinflammatory processes can lead to long term health consequences."

In some patients, however, problems persist for a long time despite appropriate therapy. The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome."

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions."

It is unknown whether subjective dysautonomia obtained from autonomic questionnaires correlates with objective dysautonomia measured by quantitative autonomic testing. The objective of our study was to determine correlations between subjective and objective measures of dysautonomia. This was a retrospective cross-sectional study conducted at Brigham and Women's Faulkner Hospital Autonomic Laboratory between 2017 and 2023 evaluating the patients who completed autonomic testing. Analyses included validated autonomic questionnaires [Survey of Autonomic Symptoms (SAS), Composite Autonomic Symptom Score 31 (Compass-31)] and standardized autonomic tests (Valsalva maneuver, deep breathing, sudomotor, and tilt test). The autonomic testing results were graded by a Quantitative scale for grading of cardiovascular reflexes, sudomotor tests and skin biopsies (QASAT), and Composite Autonomic Severity Score (CASS). Autonomic testing, QASAT, CASS, and SAS were obtained in 2627 patients, and Compass-31 in 564 patients. The correlation was strong between subjective instruments (SAS vs. Compass-31, r\u2009=\u20090.74, p\u2009<\u20090.001) and between objective instruments (QASAT vs. CASS, r\u2009=\u20090.81, p\u2009<\u20090.001). There were no correlations between SAS and QASAT nor between Compass-31 and CASS. There continued to be no correlations between subjective and objective instruments for selected diagnoses (post-acute sequelae of COVID-19, n\u2009=\u200961; postural tachycardia syndrome, 211; peripheral autonomic neuropathy, 463; myalgic encephalomyelitis/chronic fatigue syndrome, 95; preload failure, 120; post-treatment Lyme disease syndrome, 163; hypermobile Ehlers-Danlos syndrome, 213; neurogenic orthostatic hypotension, 86; diabetes type II, 71, mast cell activation syndrome, 172; hereditary alpha tryptasemia, 45). The lack of correlation between subjective and objective instruments highlights the limitations of the commonly used questionnaires with some patients overestimating and some underestimating true autonomic deficit. The diagnosis-independent subjective-objective mismatch further signifies the unmet need for reliable screening surveys. Patients who overestimate the symptom burden may represent a population with idiosyncratic autonomic-like symptomatology, which needs further study. At this time, the use of autonomic questionnaires as a replacement of autonomic testing cannot be recommended."

We evaluated whether Swedish adults who met the criteria for post-treatment Lyme disease syndrome (PTLDS) exhibited characteristics distinguishable from adults who did not, but who displayed similar symptoms and disease course after suspected previous tick-bite infection (TBI). During 2015-2018, 255 patients-referred to the Centre for Vector-borne Infections, Uppsala University Hospital, Sweden with symptoms lasting longer than six months-were recruited. Of this group, 224 completed the study. Each patient was examined by an infectious disease specialist and, besides a full medical history, underwent a panel of blood and cerebrospinal fluid laboratory tests including hematological, biochemical, microbiological and immunological analyses, and the RAND-36 scale to measure quality of life. For analysis purposes, patients were divided into five subgroups, of which one represented PTLDS. According to serological results indicating TBI and documented/ reported objective signs of Lyme disease, 85 (38%) patients fulfilled the criteria for PTLDS and were compared with the other 139 (62%) serologically classified patients. In the PTLDS group, erythema chronicum migrans (ECM) was documented/reported in 86% of patients, previous neuroborreliosis in 15%, and acrodermatitis chronica atroficans (ACA) in 3.5%. However, there were no significant differences regarding symptoms, laboratory results or disease course between patients with PTLDS and those without laboratory evidence of Borrelia exposition. Most reported symptoms were fatigue-related (70%), musculoskeletal (79%), neurological (82%) and neurocognitive (57%). Tick bites were recalled by 74%. The RAND-36 score was significantly below that of the general Swedish population. Signs of immunological/inflammatory reactivity with myositis antibodies were detected in 20% of patients, fibrinogen levels were moderately increased in 21% and elevated rheumatoid factor in 6%. The PTLDS group did not differ exclusively in any respect from the other subgroups, which either lacked previously documented/reported evidence of borreliosis or even lacked detectable serological signs of exposure to Lyme disease. The results suggest that symptoms often categorized as Chronic-Lyme-Disease (CLD) in the general debate, cannot be uniquely linked to Lyme disease. However, approximately 20% of the total group of patients showed signs of autoimmunity. Further studies are needed to elucidate the underlying causes and mechanisms of PTLDS and there is reason to consider a multifactorial approach."

In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients. The most frequent neurological syndromes were radiculoneuritis (36.84%), bilateral facial palsy (13.56%), radiculoneuritis and bilateral facial palsy (10.52%) and multiple cranial mononeuropathy (10.52%), among others. 78.9% achieved a complete recovery, and 15.79% developed post-treatment Lyme disease syndrome. Despite the high incidence of Lyme disease in Asturias, the cases based on hospital admission that can be classified as active disease are lower than those published based on hospital coding.

This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs."

Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor.

Persisting symptoms are often termed post-Lyme disease syndrome, of which etiology is not clearly understood. The aim of this study was to investigate cognitive function, possible structural changes in brain regions and level of fatigue. We have not found previous studies on neuroborreliosis that use standardized neuropsychological tests and MRI with advanced image processing to investigate if there are subtle regional changes in cortical thickness and brain volumes after treatment. We examined 68 patients treated for neuroborreliosis 6\u00a0months earlier and 66 healthy controls, with a comprehensive neuropsychological test protocol, quantitative structural MRI analysis of the brain and Fatigue Severity Scale. We found no differences between the groups in either cognitive function, cortical thickness or brain volumes. The patients had higher score on Fatigue Severity Scale 3.8 vs. 2.9 (p\u2009=\u20090.001), and more patients (25.4%) than controls (5%) had severe fatigue (p\u2009=\u20090.002), but neither mean score nor proportion of patients with severe fatigue differed from findings in the general Norwegian population. The prognosis regarding cognitive function, brain MRI findings and fatigue after adequately treated neuroborreliosis is favorable."

This review aims to describe the diagnostic errors and adverse events associated with the diagnosis and treatment of PTLDS. systematic review of the literature in the Medline and Cochrane Library databases, according to PRISMA criteria, including randomized clinical trials (RCT), observational studies, and case reports addressing diagnostic errors and adverse events published between January 2010 and November 2020 in English or French. Selection used a quadruple reading process on the basis of the titles and abstracts of the different articles, followed by a full reading. 17 studies were included: 1 RCT, 6 observational studies and 10 case reports. In the 6 observational studies, overdiagnosis rates were very high, ranging from 80 to 100%. The new diagnoses were often psychiatric, rheumatological and neurological. Disorders with somatic symptoms were often cited. Diagnostic delays were identified for cancers and frontoparietal dementia. In the RCT and observational studies, prolonged anti-infective treatments were also responsible for adverse events, with emergency room visits and/or hospitalization. The most common adverse events were diarrhea, sometimes with Clostridium difficile colitis, electrolyte abnormalities, sepsis, bacterial and fungal infections, and anaphylactic reactions. This review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS. It emphasizes the ethical imperative of the \"primum non nocere\" principle, which underscores the importance of not causing harm to patients. Physicians should exercise caution in diagnosing PTLDS and consider the potential risks associated with off-label treatments."

To guide treatment recommendations, a systematic review was performed of the available literature on specific treatment for PTLDs. A systematic literature search of MEDLINE and CENTRAL was performed. No restrictions on case definitions, study types or specific interventions were applied to enable a comprehensive overview of the available literature. Risk of bias was assessed using the Cochrane risk of bias tools for randomized controlled trials. Certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach. Outcomes of interest were quality of life, fatigue, depression and cognition as well as adverse events. After screening 1274 records, eight eligible randomized controlled trials were included. Heterogeneity was observed regarding inclusion criteria, intervention, length of treatment and outcome measures. For efficacy outcomes, results are presented narratively due to heterogeneity. Eligible studies show no statistically significant difference between antibiotics and placebo regarding quality of life, cognition and depression. Results for fatigue were inconsistent whilst studies with low risk of bias showed no statistically significant difference between antibiotics and placebo. Meta-analysis of safety outcomes showed statistically significantly more adverse events for antibiotics compared to placebo. Available literature on treatment of PTLDs is heterogeneous, but overall shows evidence of no effect of antibiotics regarding quality of life, depression, cognition and fatigue whilst showing more adverse events. Patients with suspected PTLDs should not be treated with antibiotics."

These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues."

There is currently no specific treatment for this condition. The subjects were divided into two groups: one group received 150 mg/day of Pycnogenol\u00ae alongside standard management, while the control group received only standard management. The observation period lasted for six months. Forty subjects with history of Lyme Disease and persistent symptoms completed the study: 20 in the Pycnogenol\u00ae group, 20 in the control group. No side effects from the supplementation were observed. The tolerability was optimal as no supplemented subject had to stop management and compliance was optimal with 97% of the Pycnogenol\u00ae capsules correctly used. The two groups were comparable for sex, age distribution and for their main clinical findings and signs/symptoms at inclusion. During the study, corticosteroids at low dose were used on demand in 10% of subjects using Pycnogenol\u00ae and significantly more, in 45% of the control patients (P<0.05). After 6 months, the number of patients experiencing symptoms was significantly lower in the Pycnogenol\u00ae group compared to the control group across all symptoms (P<0.05). After 6 months, the intensity of all symptoms in the Pycnogenol\u00ae group, was significantly lower, according to the scores in comparison with the control group (P<0.05). Plasma oxidative stress was significantly reduced in subjects of the Pycnogenol\u00ae group (P<0.05) in comparison with controls. The improvement in plasma oxidative stress was seen in all subjects using Pycnogenol\u00ae. Knee effusion on ultrasound was seen in 12 subjects of the supplement group at inclusion and in 3 Pycnogenol\u00ae subjects at the end of the study in comparison with 12/20 subjects in the control group at inclusion and 8/20 at the end of the study. (P<0.05). Finally, ESR (Erythrocyte sedimentation rate, a global marker of inflammation) was significantly more reduced in the Pycnogenol\u00ae group by the end of the study compared to controls (P<0.05). In conclusion, the present registry study showed that Pycnogenol\u00ae intake for 6 months in patients with persistent symptoms of Lyme disease can help relieve the main symptoms by reducing inflammation and oxidative stress. Pycnogenol's anti-inflammatory and antioxidant double activity may help safely and effectively controlling the chronic inflammatory process."

Here, we evaluated in silico the predicted binding affinities of 192 HLA-II alleles with all 15-mer peptide sequences of five Borrelia burgdorferi proteins to identify peptides with strong binding affinity, as they would be the best candidates for antibody production in response to vaccination. We found the following: (a) 226 of the 1067 peptides tested (21.2%) were found to bind strongly to HLA-II molecules; (b) decorin-binding protein A had the greatest number of strongly binding peptides; and (c) 69 HLA-II alleles (primarily of the DRB1 gene) bound with strong affinity to peptides from Borrelia burgdorferi proteins. Finally, we tested for possible susceptibility to autoimmunity by any one of the 226 peptides above by searching for their occurrence in ~84,000 proteins of the human proteome and found overlap with only two 8-mer peptide sequences (embedded within the 226 15-mer peptides), neither of which was characterized by strong binding to HLA-I, suggesting a reduced likelihood of autoimmunity. These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety.

This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination."

In some patients, however, problems persist for a long time despite appropriate therapy. The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome."

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions."

It is unknown whether subjective dysautonomia obtained from autonomic questionnaires correlates with objective dysautonomia measured by quantitative autonomic testing. The objective of our study was to determine correlations between subjective and objective measures of dysautonomia. This was a retrospective cross-sectional study conducted at Brigham and Women's Faulkner Hospital Autonomic Laboratory between 2017 and 2023 evaluating the patients who completed autonomic testing. Analyses included validated autonomic questionnaires [Survey of Autonomic Symptoms (SAS), Composite Autonomic Symptom Score 31 (Compass-31)] and standardized autonomic tests (Valsalva maneuver, deep breathing, sudomotor, and tilt test). The autonomic testing results were graded by a Quantitative scale for grading of cardiovascular reflexes, sudomotor tests and skin biopsies (QASAT), and Composite Autonomic Severity Score (CASS). Autonomic testing, QASAT, CASS, and SAS were obtained in 2627 patients, and Compass-31 in 564 patients. The correlation was strong between subjective instruments (SAS vs. Compass-31, r\u2009=\u20090.74, p\u2009<\u20090.001) and between objective instruments (QASAT vs. CASS, r\u2009=\u20090.81, p\u2009<\u20090.001). There were no correlations between SAS and QASAT nor between Compass-31 and CASS. There continued to be no correlations between subjective and objective instruments for selected diagnoses (post-acute sequelae of COVID-19, n\u2009=\u200961; postural tachycardia syndrome, 211; peripheral autonomic neuropathy, 463; myalgic encephalomyelitis/chronic fatigue syndrome, 95; preload failure, 120; post-treatment Lyme disease syndrome, 163; hypermobile Ehlers-Danlos syndrome, 213; neurogenic orthostatic hypotension, 86; diabetes type II, 71, mast cell activation syndrome, 172; hereditary alpha tryptasemia, 45). The lack of correlation between subjective and objective instruments highlights the limitations of the commonly used questionnaires with some patients overestimating and some underestimating true autonomic deficit. The diagnosis-independent subjective-objective mismatch further signifies the unmet need for reliable screening surveys. Patients who overestimate the symptom burden may represent a population with idiosyncratic autonomic-like symptomatology, which needs further study. At this time, the use of autonomic questionnaires as a replacement of autonomic testing cannot be recommended."

We evaluated whether Swedish adults who met the criteria for post-treatment Lyme disease syndrome (PTLDS) exhibited characteristics distinguishable from adults who did not, but who displayed similar symptoms and disease course after suspected previous tick-bite infection (TBI). During 2015-2018, 255 patients-referred to the Centre for Vector-borne Infections, Uppsala University Hospital, Sweden with symptoms lasting longer than six months-were recruited. Of this group, 224 completed the study. Each patient was examined by an infectious disease specialist and, besides a full medical history, underwent a panel of blood and cerebrospinal fluid laboratory tests including hematological, biochemical, microbiological and immunological analyses, and the RAND-36 scale to measure quality of life. For analysis purposes, patients were divided into five subgroups, of which one represented PTLDS. According to serological results indicating TBI and documented/ reported objective signs of Lyme disease, 85 (38%) patients fulfilled the criteria for PTLDS and were compared with the other 139 (62%) serologically classified patients. In the PTLDS group, erythema chronicum migrans (ECM) was documented/reported in 86% of patients, previous neuroborreliosis in 15%, and acrodermatitis chronica atroficans (ACA) in 3.5%. However, there were no significant differences regarding symptoms, laboratory results or disease course between patients with PTLDS and those without laboratory evidence of Borrelia exposition. Most reported symptoms were fatigue-related (70%), musculoskeletal (79%), neurological (82%) and neurocognitive (57%). Tick bites were recalled by 74%. The RAND-36 score was significantly below that of the general Swedish population. Signs of immunological/inflammatory reactivity with myositis antibodies were detected in 20% of patients, fibrinogen levels were moderately increased in 21% and elevated rheumatoid factor in 6%. The PTLDS group did not differ exclusively in any respect from the other subgroups, which either lacked previously documented/reported evidence of borreliosis or even lacked detectable serological signs of exposure to Lyme disease. The results suggest that symptoms often categorized as Chronic-Lyme-Disease (CLD) in the general debate, cannot be uniquely linked to Lyme disease. However, approximately 20% of the total group of patients showed signs of autoimmunity. Further studies are needed to elucidate the underlying causes and mechanisms of PTLDS and there is reason to consider a multifactorial approach."

Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients.

This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs."

The aim of this exploratory study was to evaluate the feasibility of protein biomarker profiling as a diagnostic platform for this category of patients and to compare these results with similarly obtained results from a group of patients with acute neuroborreliosis. Two groups of patient cohorts (Cohort 1 and 2) were analyzed for biomarkers in serum and cerebrospinal fluid (CSF); the results were used for group-level comparison. Cohort 1 comprised 158 adult patients selected from 224 previously diagnosed patients, who between October 2015 and December 2018, after referral, were enrolled and structurally investigated based on defined inclusion criteria. They displayed similar lingering symptoms, with a duration of at least 6 months, after presumed previous tick-borne infection (TBI) and are fully described in a previously published study originating from the Center for Vector-borne Infections (CVI), Uppsala University Hospital, Sweden. Cohort 2, comprised 30 patients diagnosed at Uppsala University Hospital between 2016 and 2019 with laboratory-confirmed acute neuroborreliosis. Their proteomic results, based on serum and CSF analyses, were compared with the 158 patients in Cohort 1. The expression and the concentration of potential biomarkers in each patient's serum and CSF samples were measured based on two multiplex protein panels enabling simultaneous analysis of 92 inflammatory and neurology biomarkers. The PTLDS patient subgroup showed no nominally significant proteins compared to the other CVI patients in Cohort 1. However, CVI patients with signs of inflammation, which were evenly distributed in Cohort 1, showed 16 significantly (p <0.05) different proteins in both CSF and serum, but no association was seen with laboratory-confirmed exposure to Borrelia spp or other TBIs. When comparing the two cohorts, different protein profiles were observed, with 125/148 significantly different proteins in CSF and 93/174 in serum, in patients with laboratory confirmed acute neuroborreliosis, of which 6 in CSF and 6 in serum were significant at the p <0.001 level. In this first comprehensive inflammatory and neurological biomarker profile study no differences in biomarker profiles were detected between patients with PTLDS and patients with similar persisting symptoms but who did not meet the PTLDS criteria, regardless of whether laboratory verified previous exposure to Borrelia or other TBI's were present. However, the expressed markers differed from those found in patients with confirmed acute neuroborreliosis, which does not support the view that PTLDS reflects an ongoing Borrelia infection. Further studies are needed to understand and assess the usefulness of biosignatures of patients with PTLDS before they can be applied in a clinical setting."

Brain PET scan of patients with PTLDS have demonstrated likely glial activation indicating persistent neuroinflammatory processes. It is possible that unresolved bacterial remnants can continue to cause neuroinflammation. In previous studies, we have shown that non-viable Borrelia burgdorferi can induce neuroinflammation and apoptosis in an oligodendrocyte cell line. In this follow-up study, we analyze the effect of sonicated remnants of B. burgdorferi on primary rhesus frontal cortex (FC) and dorsal root ganglion (DRG) explants. Five FC and three DRG tissue fragments from rhesus macaques were exposed to sonicated B. burgdorferi and analyzed for 26 inflammatory mediators. Live bacteria and medium alone served as positive and negative control, respectively. Tissues were also analyzed for cell types mediating inflammation and overall apoptotic changes. Non-viable B. burgdorferi induced significant levels of several inflammatory mediators in both FC and DRG, similar to live bacteria. However, the levels induced by non-viable B. burgdorferi was often (several fold) higher than those induced by live ones, especially for IL-6, CXCL8 and CCL2. This effect was also more profound in the FC than in the DRG. Although the levels often differed, both live and dead fragments induced the same mediators, with significant overlap between FC and DRG. In the FC, immunohistochemical staining for several inflammatory mediators showed the presence of multiple mediators in astrocytes, followed by microglia and oligodendrocytes, in response to bacterial remnants. Staining was also seen in endothelial cells. In the DRG, chemokine/cytokine staining was predominantly seen in S100 positive (glial) cells. B. burgdorferi remnants also induced significant levels of apoptosis in both the FC and DRG. Apoptosis was confined to S100\u2009+\u2009cells in the DRG while distinct neuronal apoptosis was also detected in most FC tissues in response to sonicated bacteria. Non-viable B. burgdorferi can continue to be neuropathogenic to both CNS and PNS tissues with effects likely more profound in the former. Persistence of remnant-induced neuroinflammatory processes can lead to long term health consequences."

When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences."

Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor.

Using matched serum and cerebrospinal fluid (CSF), we mapped the primary reactive B. burgdorferi epitopes associated with PTLDS. We found that VlsE had a greater antibody response within the PTLDS cohort than recovered patients. The reactivity to OspC-specific epitopes revealed a predominance of antibodies to OspC type K and A in the PTLDS cohort. However, the major immunodominant epitopes were similar in PTLDS and recovered patients, and we were unable to identify specific diagnostic targets for PTLDS. We found a more robust reactivity in the serum over CSF and did not identify antigenic regions that were specifically associated with the infection of the central nervous system."

It is a zoonosis caused by several species of Borrelia burgdorferi sensu lato and transmitted by the bite of infected ticks of the Ixodes ricinus complex. Lyme borreliosis in North America and Europe differs in certain respects, likely reflecting the different Borrelia species that cause human disease in these locations. The earliest manifestation of Lyme borreliosis is the skin lesion erythema migrans, which develops at the tick\u00a0bite site, typically 7-14 days after the bite. Some untreated patients will then (within the first few weeks or months after onset of the infection) develop additional erythema migrans skin lesions or other clinical manifestations such as borrelial lymphocytoma, nervous system involvement or carditis. Several months or even years after infection onset, Lyme arthritis or acrodermatitis chronica atrophicans may develop. The diagnosis of typical erythema migrans is clinical, whereas for all other manifestations\u00a0the diagnosis is supported via serological testing. Treatment with an appropriate antibiotic will result in resolution of clinical symptoms in most patients; however, some patients experience prolonged subjective symptoms, which usually improve over time. Repeated courses of antimicrobials are not beneficial except in rare cases when there is objective evidence of treatment failure."

This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination."

Existing standardized and modified two-tier tests (STT/MTT) suffer from poor detection rates in the first weeks of infection, where the antibody response, the basis of diagnosis, is developing but is not robust enough for detection. During this early window, false negative results are common, which leads to delayed treatment and increases the likelihood of developing severe symptoms. The InBios Lyme Detect Multiplex ELISA is a microarray-based assay designed to capture a set of commonly used diagnostic antibodies specific to Borrelia burgdorferi from human serum. The multiplex array captures common diagnostic antibodies, including those to C6, VlsE, and OspC, and has in-line controls. Diagnostic index scores are calculated from the relative abundance of controls and antibodies using a proprietary machine learning algorithm. The assay was evaluated here for reproducibility, accuracy, and performance. It was found to be reproducible using a group of 30 samples run in triplicate. The assay performed well in a blinded panel, correctly identifying all standard two-tier test-positive samples and controls while also detecting 21 of 79 samples that were clinically diagnosed but undetectable by standard Lyme serologic tests. There was one false positive from 66 look-alike disease samples and 146 healthy controls. The InBios assay has the potential to improve diagnostic sensitivity within the early weeks of infection while matching the specificity of current diagnostic tests. During initial Lyme disease infection, existing diagnostic tests have poor sensitivity, resulting in a high number of false-negative tests. This is due to the lag between infection and a robust immune response capable of being detected by such tests. With a multiplexed array of nine unique antibody targets specific for Borrelia burgdorferi, interpreted by a proprietary machine learning algorithm, the InBios Lyme Detect Multiplex ELISA has the potential to increase diagnostic sensitivity within the first few weeks of infection, reducing the number of false-negative tests. Improving diagnostic sensitivity during early infection would reduce the risk of developing severe symptoms, including post-treatment Lyme disease."

Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated \u223c10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection."

This review summarizes current knowledge on the pathogen-host interactions and immune responses. Early infection can be influenced by tick saliva, which suppresses local host defense and promotes spirochete survival, and by pattern recognition receptors activating proinflammatory cascades. Bbsl employs a variety of immune evasion strategies, notably impairing antigen presentation-through disruption of MHC II and IFN-\u03b3 pathways-and continuously varying surface antigens to hinder long-lasting antibody formation. Autophagy plays a central role in modulating inflammation and T helper 17 adaptive immune responses, representing an underappreciated mechanism potentially influencing disease outcome. Adaptive immunity in LB is characterized by robust but often dysregulated humoral and cellular responses, with transient germinal centers and enduring IgM production contributing to incomplete pathogen clearance. Persistent immune defects include impaired long-term B cell memory, suppressed T cell activation, and ongoing immunosuppression after pathogen clearance. Similar patterns are observed in other postinfectious fatigue syndromes. Despite advances, gaps remain in understanding mechanisms of Bbsl persistence and the immunopathology underlying chronic disease, challenging diagnosis and therapy. Emerging molecular and cellular approaches offer new avenues to address immunity, diagnostics, and prevention. A multidisciplinary effort will be needed to improve long-term patient outcomes in the evolving epidemiology of LB."

Heightened incidence levels of LD have been recorded in parts of Europe, Poland, Eastern Europe, and the Baltic States. The research aimed to inform the cost of LD and post-treatment Lyme disease syndrome (PTLDS) in Ireland through results from a patient questionnaire, disease modelling, the construction of a patient roadmap, and attempts to arrive at prevalence calculation estimates based on local data. Patient data encompassed sociodemographic particulars, disease attributes, healthcare resource utilization, and the influence on their employment status. Of 301 patients, 210 were diagnosed with LD and/or a tick-borne infection (TBI), the cohort's average age was 40.07 (SD 13.5) (N\u202f=\u202f210; Female:Male 60:40). The mean duration of symptoms in PTLDS patients was 7.15\u202fyears. The average number of visits to other healthcare professionals was 16.8 per patient. Regarding current employment status, the data indicates that 50.2% of respondents were currently working, 10.1% were unemployed, 8.7% were retired, 5.3% had caring responsibilities, 11.1% were on sick leave, and 14.5% fell into the \"Other\" category. Additionally, when asked if symptoms had affected their employment status, 69% of respondents said yes, 26% said no, and 5% did not respond. Modeling efforts show that the roadmap to care for PTLDS is challenging, leading to wandering from specialty to specialty and high healthcare utilization. Utilizing a novel method of indirect reverse estimation, our lifetime risk or cumulative incidence of PTLDS estimation is at 0.003%. Lack of data collection from Irish health authorities is leaving the issue of the cost of LD and PTLDS hard to address, despite efforts from our single-site study."

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions."

Disulfiram (DIS), a drug for alcoholism, is under investigation as a potential adjunctive treatment, but its low bioavailability, rapid metabolism, and safety concerns urge the development of improved formulations for clinical translation. Methods: Screening dissolution and permeation studies were investigated for vehicle and excipient selection, following the pharmacopeia perspectives to develop and optimize the low-dose DIS rectal suppository intended for application in post-treatment Lyme disease syndrome (PTLDS). Further characterizations were carried out by differential scanning calorimetry, X-ray diffraction, and infrared spectroscopy. Results: Cyclodextrin (CD) encapsulation was investigated to improve the aqueous solubility of the hydrophobic drug. The dissolution of DIS from fatty base suppository was very slow; it was remarkably improved by the molecular encapsulation of the drug with CDs. The dissolution of DIS from a water-soluble base was more favorable, but incomplete. In the polyethylene glycol (PEG) based suppositories, the addition of CDs already in a physical mixture ensured the dissolution of the drug. The presented drug delivery system relates to a novel preparation for rectal administration comprising a low-dose disulfiram with improved solubility and permeability by the PEG and hydroxypropyl-\u03b2-cyclodextrin (HPBCD) synergistic matrix. Conclusions: The rectal dosage form containing the drug and CD in the physical mixture is advantageous, avoiding the hepatic first-pass effect, minimizing dose-limiting toxicity, simplifying production, and fasting the availability of the repositioned drug."

While many symptoms are likely nonspecific, a recurring cluster, including severe fatigue, brain fog, cognitive decline, memory impairment, joint and muscle pain, limb numbness, headaches, and low-grade fever, is often labeled in the scientific literature as post-treatment Lyme disease syndrome (PTLDS), and in the popular media as \"chronic Lyme disease.\" Based on clinical experience and retrospective case analysis, this study hypothesizes that in many such cases, these persistent symptoms are not sequelae of Lyme borreliosis but manifestations of an undiagnosed focal infection, most commonly chronic tonsillitis or periodontal disease. The hypothesis is supported by the observation that the symptom profile of PTLDS is remarkably similar to that seen in focal infections, and by documented patient outcomes following treatment of these localized infections. This study compiles and analyzes clinical data to support the reinterpretation of PTLDS and \"chronic Lyme disease\" as misattributed focal infections in a subset of patients."

We estimate regionally adjusted prevalence of persistent symptoms, investigate seroprevalence (IgG) and ongoing infections, and examine associated demographic and clinical factors. Persons aged 18 years or older with persistent symptoms lasting six months or more attributed to tick bites or tick-borne diseases, were recruited into a nationwide cross-sectional study. Demographic data were recorded. Medical records were collected (February 2020 - April 2022) and reviewed for tick bites, tick-borne infections, antibiotic treatment, and clinical findings. Outcome measures included somatic symptoms (PHQ-15), fatigue (Fatigue Severity Scale), physical health (RAND-36), and affective symptoms (HAD Scale). Laboratory assessments included polymerase chain reaction (PCR) analysis of blood samples for Borrelia burgdorferi (Bb) and other known tick-borne pathogens, along with IgG antibody detection. The highest prevalence of persistent symptoms attributed to tick bites or tick-borne diseases was found in southwestern Norway (0.152-0.155%); the lowest was in the north (0.033%), which also had significantly lower Bb-IgG seroprevalence (15.4% compared to the national average 37.5%). Symptom persistence was not associated with confirmed tick exposure or tick-borne infection. Somatic symptoms were associated with low physical activity and comorbidity. Fatigue and poor physical health were strongly associated with underemployment. Fatigue was also associated with depressive symptoms, low activity, sick leave, and comorbidities. Persistent symptoms were most prevalent in tick-endemic regions but were not associated with prior tick exposure or tick-borne infections. Symptom burden was primarily associated with comorbidities, especially physical inactivity and underemployment. Not applicable."

Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes. KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions.

Characterized by fatigue, generalized myalgias, and cognitive impairment, PTLD symptomatology closely resembles long COVID and other post-acute infection syndromes. While prior studies suggest immune dysregulation as a factor in PTLD pathogenesis, the mechanisms underlying its heterogeneous presentation and severity remain unclear. To associate symptom burden with discrete immune phenotypes, we applied factor analysis to self-reported symptom data from 272 PTLD patients to generate patient subgroups. We then immunophenotyped peripheral blood cells of these individuals and 28 healthy controls through 19-parameter flow cytometry and cytokine profiling to associate PTLD status and the newly defined subgroups with specific immune states. Our PTLD cohort had fewer circulating CXCR5+ CD4+ na\u00efve T cells relative to healthy controls (5.2% vs. 8.3%, Padj < 0.001). These cells were positively associated with musculoskeletal pain in PTLD participants, but not healthy controls. This and additional immunophenotypic alterations, including an increased prevalence of CXCR3+ CCR4- CCR6- CD8 T cells (43.1% vs. 25.7%, Padj < 0.01), permitted the creation of an elastic net classifier which identified PTLD with moderate efficacy (AUC 0.83). Measurement of cytokines did not reveal associations with PTLD and did not improve the performance of the model. While we could not identify immune features which distinguished all patient subgroups, we did observe a female-specific increase in central memory CD8 T cells restricted to one high-fatigue patient subgroup. Additionally, factor analysis revealed multiple associations between immune cell frequency and the severity of specific symptoms. Collectively, our findings add to growing evidence of immune dysfunction as a prominent feature of PTLD."

We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis.

Methods: We created a machine-learning model that distinguishes PASC from PASC-similar diseases. The model was trained to recognize PASC-dysregulated metabolites (p \u2264 0.05) using molecular descriptors. Results: Our multi-layer perceptron model accurately recognizes PASC-dysregulated metabolites in the independent testing set, with an AUC-ROC of 0.8991, and differentiates PASC from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, postural orthostatic tachycardia syndrome (POTS), and irritable bowel syndrome (IBS). However, it was unable to differentiate fibromyalgia (FM) from PASC. Conclusions: By creating and testing models pairwise on each of these diseases, we elucidated the unique strength of the similarity between FM and PASC relative to other PASC-similar diseases. Our approach is unique to PASC diagnosis, and our use of molecular descriptors enables our model to work with any metabolite where molecular descriptors can be identified, as these descriptors can be generated and compared for any metabolite. Our study presents a novel approach to PASC diagnosis that partially circumvents the lengthy process of exclusion, potentially facilitating faster interventions and improved patient outcomes."

Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar.

When these symptoms are unexplained by other conditions and persist for \u2265\u20096 months, this condition is called post-treatment Lyme disease symptoms or syndrome (PTLDS). The pathogenesis of PTLDS is unknown and no specific diagnostic biomarkers have been identified. In this study, we used a high-density peptide array to examine antibody responses to >\u200960 primary antigens of B. burgdorferi from a cohort of patients diagnosed with PTLDS and recovered patients with similar Lyme disease manifestations. Using matched serum and cerebrospinal fluid (CSF), we mapped the primary reactive B. burgdorferi epitopes associated with PTLDS. We found that VlsE had a greater antibody response within the PTLDS cohort than recovered patients. The reactivity to OspC-specific epitopes revealed a predominance of antibodies to OspC type K and A in the PTLDS cohort. However, the major immunodominant epitopes were similar in PTLDS and recovered patients, and we were unable to identify specific diagnostic targets for PTLDS. We found a more robust reactivity in the serum over CSF and did not identify antigenic regions that were specifically associated with the infection of the central nervous system."

It is a zoonosis caused by several species of Borrelia burgdorferi sensu lato and transmitted by the bite of infected ticks of the Ixodes ricinus complex. Lyme borreliosis in North America and Europe differs in certain respects, likely reflecting the different Borrelia species that cause human disease in these locations. The earliest manifestation of Lyme borreliosis is the skin lesion erythema migrans, which develops at the tick\u00a0bite site, typically 7-14 days after the bite. Some untreated patients will then (within the first few weeks or months after onset of the infection) develop additional erythema migrans skin lesions or other clinical manifestations such as borrelial lymphocytoma, nervous system involvement or carditis. Several months or even years after infection onset, Lyme arthritis or acrodermatitis chronica atrophicans may develop. The diagnosis of typical erythema migrans is clinical, whereas for all other manifestations\u00a0the diagnosis is supported via serological testing. Treatment with an appropriate antibiotic will result in resolution of clinical symptoms in most patients; however, some patients experience prolonged subjective symptoms, which usually improve over time. Repeated courses of antimicrobials are not beneficial except in rare cases when there is objective evidence of treatment failure."

This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination."

Existing standardized and modified two-tier tests (STT/MTT) suffer from poor detection rates in the first weeks of infection, where the antibody response, the basis of diagnosis, is developing but is not robust enough for detection. During this early window, false negative results are common, which leads to delayed treatment and increases the likelihood of developing severe symptoms. The InBios Lyme Detect Multiplex ELISA is a microarray-based assay designed to capture a set of commonly used diagnostic antibodies specific to Borrelia burgdorferi from human serum. The multiplex array captures common diagnostic antibodies, including those to C6, VlsE, and OspC, and has in-line controls. Diagnostic index scores are calculated from the relative abundance of controls and antibodies using a proprietary machine learning algorithm. The assay was evaluated here for reproducibility, accuracy, and performance. It was found to be reproducible using a group of 30 samples run in triplicate. The assay performed well in a blinded panel, correctly identifying all standard two-tier test-positive samples and controls while also detecting 21 of 79 samples that were clinically diagnosed but undetectable by standard Lyme serologic tests. There was one false positive from 66 look-alike disease samples and 146 healthy controls. The InBios assay has the potential to improve diagnostic sensitivity within the early weeks of infection while matching the specificity of current diagnostic tests. During initial Lyme disease infection, existing diagnostic tests have poor sensitivity, resulting in a high number of false-negative tests. This is due to the lag between infection and a robust immune response capable of being detected by such tests. With a multiplexed array of nine unique antibody targets specific for Borrelia burgdorferi, interpreted by a proprietary machine learning algorithm, the InBios Lyme Detect Multiplex ELISA has the potential to increase diagnostic sensitivity within the first few weeks of infection, reducing the number of false-negative tests. Improving diagnostic sensitivity during early infection would reduce the risk of developing severe symptoms, including post-treatment Lyme disease."

Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated \u223c10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection."

Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms."

This review summarizes current knowledge on the pathogen-host interactions and immune responses. Early infection can be influenced by tick saliva, which suppresses local host defense and promotes spirochete survival, and by pattern recognition receptors activating proinflammatory cascades. Bbsl employs a variety of immune evasion strategies, notably impairing antigen presentation-through disruption of MHC II and IFN-\u03b3 pathways-and continuously varying surface antigens to hinder long-lasting antibody formation. Autophagy plays a central role in modulating inflammation and T helper 17 adaptive immune responses, representing an underappreciated mechanism potentially influencing disease outcome. Adaptive immunity in LB is characterized by robust but often dysregulated humoral and cellular responses, with transient germinal centers and enduring IgM production contributing to incomplete pathogen clearance. Persistent immune defects include impaired long-term B cell memory, suppressed T cell activation, and ongoing immunosuppression after pathogen clearance. Similar patterns are observed in other postinfectious fatigue syndromes. Despite advances, gaps remain in understanding mechanisms of Bbsl persistence and the immunopathology underlying chronic disease, challenging diagnosis and therapy. Emerging molecular and cellular approaches offer new avenues to address immunity, diagnostics, and prevention. A multidisciplinary effort will be needed to improve long-term patient outcomes in the evolving epidemiology of LB."

Heightened incidence levels of LD have been recorded in parts of Europe, Poland, Eastern Europe, and the Baltic States. The research aimed to inform the cost of LD and post-treatment Lyme disease syndrome (PTLDS) in Ireland through results from a patient questionnaire, disease modelling, the construction of a patient roadmap, and attempts to arrive at prevalence calculation estimates based on local data. Patient data encompassed sociodemographic particulars, disease attributes, healthcare resource utilization, and the influence on their employment status. Of 301 patients, 210 were diagnosed with LD and/or a tick-borne infection (TBI), the cohort's average age was 40.07 (SD 13.5) (N\u202f=\u202f210; Female:Male 60:40). The mean duration of symptoms in PTLDS patients was 7.15\u202fyears. The average number of visits to other healthcare professionals was 16.8 per patient.

Additionally, when asked if symptoms had affected their employment status, 69% of respondents said yes, 26% said no, and 5% did not respond. Modeling efforts show that the roadmap to care for PTLDS is challenging, leading to wandering from specialty to specialty and high healthcare utilization. Utilizing a novel method of indirect reverse estimation, our lifetime risk or cumulative incidence of PTLDS estimation is at 0.003%. Lack of data collection from Irish health authorities is leaving the issue of the cost of LD and PTLDS hard to address, despite efforts from our single-site study."

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden.

Disulfiram (DIS), a drug for alcoholism, is under investigation as a potential adjunctive treatment, but its low bioavailability, rapid metabolism, and safety concerns urge the development of improved formulations for clinical translation. Methods: Screening dissolution and permeation studies were investigated for vehicle and excipient selection, following the pharmacopeia perspectives to develop and optimize the low-dose DIS rectal suppository intended for application in post-treatment Lyme disease syndrome (PTLDS). Further characterizations were carried out by differential scanning calorimetry, X-ray diffraction, and infrared spectroscopy. Results: Cyclodextrin (CD) encapsulation was investigated to improve the aqueous solubility of the hydrophobic drug. The dissolution of DIS from fatty base suppository was very slow; it was remarkably improved by the molecular encapsulation of the drug with CDs. The dissolution of DIS from a water-soluble base was more favorable, but incomplete. In the polyethylene glycol (PEG) based suppositories, the addition of CDs already in a physical mixture ensured the dissolution of the drug. The presented drug delivery system relates to a novel preparation for rectal administration comprising a low-dose disulfiram with improved solubility and permeability by the PEG and hydroxypropyl-\u03b2-cyclodextrin (HPBCD) synergistic matrix. Conclusions: The rectal dosage form containing the drug and CD in the physical mixture is advantageous, avoiding the hepatic first-pass effect, minimizing dose-limiting toxicity, simplifying production, and fasting the availability of the repositioned drug."

Characterized by fatigue, generalized myalgias, and cognitive impairment, PTLD symptomatology closely resembles long COVID and other post-acute infection syndromes. While prior studies suggest immune dysregulation as a factor in PTLD pathogenesis, the mechanisms underlying its heterogeneous presentation and severity remain unclear. To associate symptom burden with discrete immune phenotypes, we applied factor analysis to self-reported symptom data from 272 PTLD patients to generate patient subgroups. We then immunophenotyped peripheral blood cells of these individuals and 28 healthy controls through 19-parameter flow cytometry and cytokine profiling to associate PTLD status and the newly defined subgroups with specific immune states. Our PTLD cohort had fewer circulating CXCR5+ CD4+ na\u00efve T cells relative to healthy controls (5.2% vs. 8.3%, Padj < 0.001). These cells were positively associated with musculoskeletal pain in PTLD participants, but not healthy controls. This and additional immunophenotypic alterations, including an increased prevalence of CXCR3+ CCR4- CCR6- CD8 T cells (43.1% vs. 25.7%, Padj < 0.01), permitted the creation of an elastic net classifier which identified PTLD with moderate efficacy (AUC 0.83). Measurement of cytokines did not reveal associations with PTLD and did not improve the performance of the model. While we could not identify immune features which distinguished all patient subgroups, we did observe a female-specific increase in central memory CD8 T cells restricted to one high-fatigue patient subgroup. Additionally, factor analysis revealed multiple associations between immune cell frequency and the severity of specific symptoms.

While Long COVID is newly defined, PAIS have been described for over a century following epidemic infections. Multiple pathogens - including influenza, Epstein-Barr virus, and Borrelia burgdorferi, among others - can precipitate persistent, poorly understood symptoms. Chronic illnesses such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) have long been linked to infectious triggers. This recurring association highlights critical knowledge gaps and underscores the need for systematic investigation. Unlike prior pandemics, the current era offers advanced technologies and analytic tools to address these gaps. Defining the biology of Long COVID may yield broader insights into host-pathogen interactions and mechanisms of chronic illness."

In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients. The most frequent neurological syndromes were radiculoneuritis (36.84%), bilateral facial palsy (13.56%), radiculoneuritis and bilateral facial palsy (10.52%) and multiple cranial mononeuropathy (10.52%), among others. 78.9% achieved a complete recovery, and 15.79% developed post-treatment Lyme disease syndrome. Despite the high incidence of Lyme disease in Asturias, the cases based on hospital admission that can be classified as active disease are lower than those published based on hospital coding. The main source of diagnostic error is positive serological results, without other clinical context, especially in patients studied for cognitive impairment or encephalopathy."

Post-Acute Sequelae of SARS-CoV-2 Infection (also known as Post-Acute Sequelae of COVID-19 (PASC) or more commonly, Long COVID) occurs in the aftermath of COVID-19 and is poorly understood despite its widespread effects. Methods: We created a machine-learning model that distinguishes PASC from PASC-similar diseases. The model was trained to recognize PASC-dysregulated metabolites (p \u2264 0.05) using molecular descriptors. Results: Our multi-layer perceptron model accurately recognizes PASC-dysregulated metabolites in the independent testing set, with an AUC-ROC of 0.8991, and differentiates PASC from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, postural orthostatic tachycardia syndrome (POTS), and irritable bowel syndrome (IBS). However, it was unable to differentiate fibromyalgia (FM) from PASC. Conclusions: By creating and testing models pairwise on each of these diseases, we elucidated the unique strength of the similarity between FM and PASC relative to other PASC-similar diseases. Our approach is unique to PASC diagnosis, and our use of molecular descriptors enables our model to work with any metabolite where molecular descriptors can be identified, as these descriptors can be generated and compared for any metabolite. Our study presents a novel approach to PASC diagnosis that partially circumvents the lengthy process of exclusion, potentially facilitating faster interventions and improved patient outcomes."

This article explores the historical and contemporary issues in diagnosing such conditions, emphasizing the fragmentation of medical and psychiatric knowledge, biases in clinical guidelines, and the mismanagement of complex illnesses. Diagnostic errors often arise from insufficient integration between general medicine and psychiatry, compounded by the reliance on population-based guidelines that neglect individual patient needs. Misclassification of conditions like myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, and fibromyalgia as psychosomatic or psychogenic has led to stigmatization and delayed care. While these conditions are referenced as emblematic examples of misclassified and poorly understood disorders, the five clinical cases discussed in this article do not directly illustrate these diseases. Instead, they exemplify shared diagnostic and ethical dilemmas at the medicine-psychiatry interface, including uncertainty, fragmentation, and the risk of epistemic injustice. The article critically examines terms like medically unexplained symptoms and functional disorders, highlighting their limitations and potential for misuse. Case examples underscore the consequences of diagnostic inaccuracies and the urgent need for improved approaches. Ethical considerations are also explored, emphasizing respecting patient experiences, promoting individualized care, and acknowledging the inherent uncertainties in medical diagnosis. Advances in technologies such as brain imaging and molecular diagnostics offer hope for bridging the gap between psychiatry and medicine, enabling more accurate assessments and better patient outcomes. The article concludes by advocating comprehensive training at the medicine-psychiatry interface and a patient-centered approach that integrates clinical observation, research insights, and a nuanced understanding of mind-body dynamics."

However, diagnosis can be particularly challenging in resource-limited settings where advanced tests are not readily available. Misclassification may result in non-selective chemotherapy exposure and increased toxicity. Reporting such cases is important to highlight diagnostic challenges in resource-limited countries. A 51-year-old male presented with abdominal discomfort, weight loss, and fatigue. Examination revealed splenomegaly. Initial evaluation suggested lymphoplasmacytic lymphoma, and the patient received multi-agent chemotherapy (R-CHOP), which was complicated by severe cytopenias. Splenectomy was performed, yielding a spleen weighing 2216\u00a0g. Histopathology and immunophenotyping confirmed hairy cell leukemia. Molecular testing for BRAF V600E (the gold standard for diagnosis) was unavailable due to financial and infrastructural restrictions. Treatment was switched to single-agent cladribine, resulting in marked clinical improvement and a significant reduction in chemotherapy adverse effects. Follow-up imaging and blood work revealed that the patient was in complete remission. In our case, we emphasize the diagnostic challenges of HCL in low-resource environments and clarify how the empirical administration of R-CHOP chemotherapy led to unnecessary toxicity and suboptimal outcomes. Splenectomy played a crucial diagnostic role when bone marrow tests were directional but not conclusive. We provide an extensive review of differential diagnoses, immunophenotypic hallmarks, what lies beyond the BRAF V600E mutation, and therapeutic approaches. Early recognition of HCL is crucial to avoid delayed optimal therapy and to enhance patient outcomes. This case emphasizes the critical role of morphology and immunophenotyping in confirming HCL, especially in resource-limited countries."

The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects.

The pathogenesis, ecology, and epidemiology of Lyme disease have been well described, and antimicrobial treatment is very effective. There has been controversy about whether infection can persist and cause chronic symptoms despite treatment with antimicrobials. This review summarizes recent studies that have addressed this issue. The pathogenesis of persistent nonspecific symptoms in patients who were treated for Lyme disease is poorly understood, and the validity of results of attempts to demonstrate persistent infection with B. burgdorferi has not been established. One study attempted to use xenodiagnosis to detect B. burgdorferi in patients who have been treated for Lyme disease. Another study assessed whether repeated episodes of erythema migrans were due to the same or different strains of B. burgdorferi. A possible cause of persistent arthritis in some treated patients is slow clearance of nonviable organisms that may lead to prolonged inflammation. The results of all of these studies continue to provide evidence that viable B. burgdorferi do not persist in patients who receive conventional antimicrobial treatment for Lyme disease. Patients with persistent symptoms possibly associated with Lyme disease often provide a challenge for clinicians. Recent studies have provided additional evidence that viable B. burgdorferi do not persist after conventional treatment with antimicrobials, indicating that ongoing symptoms in patients who received conventional treatment for Lyme disease should not be attributed to persistent active infection."

An accumulating body of evidence suggests that Lyme disease is the appropriate diagnosis for only a minority of patients in whom it is suspected. In prospective studies of Lyme disease, very few patients go on to have a chronic syndrome dominated by subjective complaints. There is no systematic evidence that Borrelia burgdorferi, the etiology of Lyme disease, can be identified in patients with chronic symptoms following treated Lyme disease. Multiple prospective trials have revealed that prolonged courses of antibiotics neither prevent nor alleviate such post-Lyme syndromes. Extended courses of intravenous antibiotics have resulted in severe adverse events, which in light of their lack of efficacy, make them contraindicated."

These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues."

Identification of an erythema migrans rash following a tick bite is the only clinical manifestation sufficient to make the diagnosis of Lyme disease in the absence of laboratory confirmation. The Centers for Disease Control and Prevention recommends a two-tier serologic testing protocol using an enzyme-linked immunosorbent assay initially, followed by the more specific Western blot to confirm the diagnosis when the assay samples are positive or equivocal. The treatment of Lyme disease is determined mainly by the clinical manifestations of the disease. Doxycycline is often the preferred agent for oral treatment because of its activity against other tick-borne illnesses. Preventive measures include avoiding areas with high tick burdens, wearing protective clothing, using tick repellants (e.g., diethyltoluamide [DEET]), performing frequent body checks and bathing following outdoor activities, and instituting environmental landscape modifications (e.g., grass mowing, deer exclusion fencing) to reduce the tick burden.

The following three criteria should be fulfilled for definite LNB, and two of them for possible LNB: (i) neurological symptoms; (ii) cerebrospinal fluid (CSF) pleocytosis; (iii) Bb-specific antibodies produced intrathecally. PCR and CSF culture may be corroborative if symptom duration is <6 weeks, when Bb antibodies may be absent. PCR is otherwise not recommended. There is also not enough evidence to recommend the following tests for diagnostic purposes: microscope-based assays, chemokine CXCL13, antigen detection, immune complexes, lymphocyte transformation test, cyst formation, lymphocyte markers. Adult patients with definite or possible acute LNB (symptom duration <6 months) should be offered a single 14-day course of antibiotic treatment. Oral doxycycline (200 mg daily) and intravenous (IV) ceftriaxone (2 g daily) are equally effective in patients with symptoms confined to the peripheral nervous system, including meningitis (level A). Patients with CNS manifestations should be treated with IV ceftriaxone (2 g daily) for 14 days and late LNB (symptom duration >6 months) for 3 weeks (good practice points). Children should be treated as adults, except that doxycycline is contraindicated under 8 years of age (nine in some countries).

It is a common illness in temperate countries, especially the United States, but the incidence is increasing across continents due to increasing reforestation, travel and adventure tourism, increased intrusion in the vector habitat, and changing habitat of the vector. Transmission primarily occurs via bite of an infected tick (Ixodes spp.). The appearance of an erythema migrans rash following a tick bite is diagnostic of early Lyme disease even without laboratory evidence. Borrelia lymphocytoma and acrodermatitis chronica atrophicans along with multisystem involvement occur in late disseminated and chronic stages. A two-step serologic testing protocol using an enzyme-linked immunosorbent assay (ELISA) followed by confirmation of positive and equivocal results by Western immunoblot is recommended for the diagnosis. Transplacental transmission to infant occurs in the first trimester with possible congenital Lyme disease making treatment imperative during antenatal period. The treatment is most effective in the early stages of the disease, whereas rheumatological, neurological, or other late manifestations remain difficult to treat with antibiotics alone. Treatment with oral doxycycline is preferred for its additional activity against other tick-borne illnesses which may occur concurrently in 10%-15% of cases. New-generation cephalosporins and azithromycin are alternative options in patients with doxycycline contraindications. No vaccine is available and one episode of the disease will not confer life-long immunity; thus, preventive measures remain a priority.

Seven of the 18 herbs reviewed had evidence for in-vitro activity against B. burgdorferi. These compounds included: (1) cat's claw (2) cryptolepis, (3) Chinese skullcap, (4) Japanese knotweed, (5) sweet wormwood, (6) thyme, and (7) oil of oregano. With the exception of oil of oregano these compounds also have anti-inflammatory activity. In vivo data and clinical trials are lacking. Clinicians should be cautious as many of the identified compounds have drug interactions and additive effects that could lead to increased risks for bleeding, hypotension, and hypoglycemia. Many of the herbs that alternative and integrative practitioners use to treat Lyme disease have anti-inflammatory effects that may contribute to patients' perceptions of symptomatic improvement. Some herbs have limited demonstrated anti-borrelial activity in vitro, but in-vivo data and clinical trial data is lacking. Further research is required to determine the efficacy, safety and appropriate use of these herbs for this patient population."

Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms."

Design: This was a prospective longitudinal single-center pilot study conducted from January 2019 to December 2020. Setting/Location: University of Maryland Lyme Program, Baltimore Maryland. Subjects: Persons presenting for Lyme evaluation for symptoms attributed to Lyme disease. Interventions: Participants attended two 1-h individual instructional sessions consisting of Ayurveda-based dietary intervention and breath-coordinated mind-body practice to be used for home practice. Outcome measures: Standard measures of impact were obtained at baseline, 1, 3, 6, and 12 months using the following validated survey instruments: Perceived Stress Scale (PSS), PROMIS Global Health v1.2 (GH), and PROMIS 29 v2.0 survey. Results: From 216 patients presenting for Lyme evaluation, 19 participants enrolled with 84% completing the study (N\u2009=\u200916). Baseline PROMIS GH scores consisting of general Physical Health (GPH) and general Mental Health (GMH) scores were lower in the study population than in the general U.S. population.

Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes. KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions. However, larger, standardized RCTs with active comparators, biomarkers, and longer follow-up are needed.

To determine whether antibiotic therapy improves cognitive function in two randomized double-blind placebo-controlled studies of patients with PTCLD. A total of 129 patients with a physician-documented history of Lyme disease from three study sites in the northeast United States were studied. Seventy-eight were seropositive for IgG antibodies against Borrelia burgdorferi, and 51 were seronegative. Patients in each group were randomly assigned to receive IV ceftriaxone 2 g daily for 30 days followed by oral doxycycline 200 mg daily for 60 days or matching IV and oral placebos. Assessments were made at 90 and 180 days after treatment. Symptom severity was measured from the cognitive functioning, pain, and role functioning scales of the Medical Outcomes Study (MOS). Memory, attention, and executive functioning were assessed using objective tests. Mood was assessed using the Beck Depression Inventory and Minnesota Multiphasic Personality Inventory. There were no significant baseline differences between seropositive and seronegative groups. Both groups reported a high frequency of MOS symptoms, depression, and somatic complaints but had normal baseline neuropsychological test scores. The combined groups showed significant decreases in MOS symptoms, higher objective test scores, and improved mood between baseline and 90 days. However, there were no significant differences between those receiving antibiotics and placebo. Patients with post-treatment chronic Lyme disease who have symptoms but show no evidence of persisting Borrelia infection do not show objective evidence of cognitive impairment. Additional antibiotic therapy was not more beneficial than administering placebo."

In some patients, however, problems persist for a long time despite appropriate therapy. The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome."

The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences."

The pathogenesis, ecology, and epidemiology of Lyme disease have been well described, and antimicrobial treatment is very effective. There has been controversy about whether infection can persist and cause chronic symptoms despite treatment with antimicrobials. This review summarizes recent studies that have addressed this issue. The pathogenesis of persistent nonspecific symptoms in patients who were treated for Lyme disease is poorly understood, and the validity of results of attempts to demonstrate persistent infection with B. burgdorferi has not been established. One study attempted to use xenodiagnosis to detect B. burgdorferi in patients who have been treated for Lyme disease. Another study assessed whether repeated episodes of erythema migrans were due to the same or different strains of B. burgdorferi. A possible cause of persistent arthritis in some treated patients is slow clearance of nonviable organisms that may lead to prolonged inflammation. The results of all of these studies continue to provide evidence that viable B. burgdorferi do not persist in patients who receive conventional antimicrobial treatment for Lyme disease. Patients with persistent symptoms possibly associated with Lyme disease often provide a challenge for clinicians. Recent studies have provided additional evidence that viable B. burgdorferi do not persist after conventional treatment with antimicrobials, indicating that ongoing symptoms in patients who received conventional treatment for Lyme disease should not be attributed to persistent active infection."

The hypothesis that patients with PLDS may harbor hidden reservoirs of Borrelia burgdorferi after their initial antibiotic treatment is difficult to accept. The prospective, double-blind studies contradict this point of view. Also, recently published research applying xenodiagnosis to PLDS supports the opinion that PLDS most likely has an autoimmune background.

This is exacerbated by the lack of a clinical or microbiologic definition, and the commonality of chronic symptoms in the general population. An accumulating body of evidence suggests that Lyme disease is the appropriate diagnosis for only a minority of patients in whom it is suspected. In prospective studies of Lyme disease, very few patients go on to have a chronic syndrome dominated by subjective complaints. There is no systematic evidence that Borrelia burgdorferi, the etiology of Lyme disease, can be identified in patients with chronic symptoms following treated Lyme disease. Multiple prospective trials have revealed that prolonged courses of antibiotics neither prevent nor alleviate such post-Lyme syndromes. Extended courses of intravenous antibiotics have resulted in severe adverse events, which in light of their lack of efficacy, make them contraindicated."

These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues."

Despite extensive study, there is currently no clear evidence that post-Lyme disease syndrome is caused by persistent infection with B burgdorferi. Four randomized placebo-controlled studies have shown that antibiotic therapy offers no sustained benefit to patients who have post-Lyme disease syndrome. These studies also showed a substantial placebo effect and a significant risk of treatment-related adverse events. Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed."

Transmission occurs primarily through the bite of an infected deer tick (Ixodes scapularis). Identification of an erythema migrans rash following a tick bite is the only clinical manifestation sufficient to make the diagnosis of Lyme disease in the absence of laboratory confirmation. The Centers for Disease Control and Prevention recommends a two-tier serologic testing protocol using an enzyme-linked immunosorbent assay initially, followed by the more specific Western blot to confirm the diagnosis when the assay samples are positive or equivocal. The treatment of Lyme disease is determined mainly by the clinical manifestations of the disease. Doxycycline is often the preferred agent for oral treatment because of its activity against other tick-borne illnesses. Preventive measures include avoiding areas with high tick burdens, wearing protective clothing, using tick repellants (e.g., diethyltoluamide [DEET]), performing frequent body checks and bathing following outdoor activities, and instituting environmental landscape modifications (e.g., grass mowing, deer exclusion fencing) to reduce the tick burden. Although there is controversy regarding treatment of post-Lyme disease syndrome and chronic Lyme disease, there is no biologic or clinical trial evidence indicating that prolonged antibiotic therapy is of benefit."

To present evidence-based recommendations for diagnosis and treatment. Data were analysed according to levels of evidence as suggested by EFNS. The following three criteria should be fulfilled for definite LNB, and two of them for possible LNB: (i) neurological symptoms; (ii) cerebrospinal fluid (CSF) pleocytosis; (iii) Bb-specific antibodies produced intrathecally. PCR and CSF culture may be corroborative if symptom duration is <6 weeks, when Bb antibodies may be absent. PCR is otherwise not recommended. There is also not enough evidence to recommend the following tests for diagnostic purposes: microscope-based assays, chemokine CXCL13, antigen detection, immune complexes, lymphocyte transformation test, cyst formation, lymphocyte markers. Adult patients with definite or possible acute LNB (symptom duration <6 months) should be offered a single 14-day course of antibiotic treatment. Oral doxycycline (200 mg daily) and intravenous (IV) ceftriaxone (2 g daily) are equally effective in patients with symptoms confined to the peripheral nervous system, including meningitis (level A). Patients with CNS manifestations should be treated with IV ceftriaxone (2 g daily) for 14 days and late LNB (symptom duration >6 months) for 3 weeks (good practice points). Children should be treated as adults, except that doxycycline is contraindicated under 8 years of age (nine in some countries). If symptoms persist for more than 6 months after standard treatment, the condition is often termed post-Lyme disease syndrome (PLDS). Antibiotic therapy has no impact on PLDS (level A)."

It is a common illness in temperate countries, especially the United States, but the incidence is increasing across continents due to increasing reforestation, travel and adventure tourism, increased intrusion in the vector habitat, and changing habitat of the vector. Transmission primarily occurs via bite of an infected tick (Ixodes spp.). The appearance of an erythema migrans rash following a tick bite is diagnostic of early Lyme disease even without laboratory evidence. Borrelia lymphocytoma and acrodermatitis chronica atrophicans along with multisystem involvement occur in late disseminated and chronic stages. A two-step serologic testing protocol using an enzyme-linked immunosorbent assay (ELISA) followed by confirmation of positive and equivocal results by Western immunoblot is recommended for the diagnosis. Transplacental transmission to infant occurs in the first trimester with possible congenital Lyme disease making treatment imperative during antenatal period. The treatment is most effective in the early stages of the disease, whereas rheumatological, neurological, or other late manifestations remain difficult to treat with antibiotics alone. Treatment with oral doxycycline is preferred for its additional activity against other tick-borne illnesses which may occur concurrently in 10%-15% of cases. New-generation cephalosporins and azithromycin are alternative options in patients with doxycycline contraindications. No vaccine is available and one episode of the disease will not confer life-long immunity; thus, preventive measures remain a priority. The concept of post-Lyme disease syndrome versus chronic Lyme disease remains contested for want of robust evidence favoring benefits of prolonged antibiotic therapy."

However, in about 5% of patients so called Post-Lyme disease syndrome (PLSD) develops. It is defined as a syndrome of subjective symptoms persisting despite proper treatment of Borrelia burgdorferi infection. The most common symptoms include: fatigue, muscle and joint pain, and problems with memory and concentration. Pathogenesis of PLDS remains unknown. The differential diagnosis should include neurological, rheumatic and mental diseases. Till now there is no causative treatment of PLDS. In relieving symptom rehabilitation, painkillers, anti-inflammatory and antidepressants medicines are recommended. Emotional and psychological supports are also necessary. Non-specific symptoms reported by patients with post- Lyme disease syndrome raise the suspicion of other pathologies. This can lead to misdiagnosis and implementation of unnecessary, potentially harmful to the patient's therapy.

While most patients successfully recover with antibiotics, some patients experience persistent symptoms for months to years. Patients who attribute chronic symptoms to Lyme disease commonly use herbal supplements. The complexity, variability in dose and formulation, and lack of data for these herbal compounds make it difficult to assess their efficacy and safety. This review examines the evidence for the antimicrobial activity, safety, and drug-drug interactions of 18 herbal supplements that patients commonly use for treatment of persistent symptoms attributed to Lyme disease. The research team performed a narrative review by searching the PubMed, Embase, Scopus, Natural Medicines databases, and NCCIH website. The search used the keywords for 18 herbal compounds: (1) andrographis (Andrographis paniculate), (2) astragalus (Astragalus propinquus), (3) berberine, (4) cat's claw bark (Uncaria tomentosa), (5) cordyceps (Cordyceps sinensis), (6) cryptolepis (Cryptolepis sanguinolenta), (7) Chinese skullcap (Scutellaria baicalensis), (8) garlic (Allium sativum), (9) Japanese knotwood (Polygonum cuspidatum), (10) reishi mushrooms (Ganoderma lucidum), (11) sarsaparilla (Smilax medica), (12) Siberian ginseng (Eleutherococcus senticosus), (13) sweet wormwood (Artemisia annua), (14) teasle root (Dipsacus fullonum), (15) lemon balm (Melissa officinalis), (16) oil of oregano (Origanum vulgare), (17) peppermint (Mentha x piperita), and (18) thyme (Thymus vulgaris). The team also searched for terms related to protocols, including Dr. Rawls' protocol and the Buhner protocol. University of Maryland Medical Center, Baltimore MD. Seven of the 18 herbs reviewed had evidence for in-vitro activity against B. burgdorferi. These compounds included: (1) cat's claw (2) cryptolepis, (3) Chinese skullcap, (4) Japanese knotweed, (5) sweet wormwood, (6) thyme, and (7) oil of oregano. With the exception of oil of oregano these compounds also have anti-inflammatory activity. In vivo data and clinical trials are lacking. Clinicians should be cautious as many of the identified compounds have drug interactions and additive effects that could lead to increased risks for bleeding, hypotension, and hypoglycemia. Many of the herbs that alternative and integrative practitioners use to treat Lyme disease have anti-inflammatory effects that may contribute to patients' perceptions of symptomatic improvement. Some herbs have limited demonstrated anti-borrelial activity in vitro, but in-vivo data and clinical trial data is lacking. Further research is required to determine the efficacy, safety and appropriate use of these herbs for this patient population."

Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms."

Subjects: Persons presenting for Lyme evaluation for symptoms attributed to Lyme disease. Interventions: Participants attended two 1-h individual instructional sessions consisting of Ayurveda-based dietary intervention and breath-coordinated mind-body practice to be used for home practice. Outcome measures: Standard measures of impact were obtained at baseline, 1, 3, 6, and 12 months using the following validated survey instruments: Perceived Stress Scale (PSS), PROMIS Global Health v1.2 (GH), and PROMIS 29 v2.0 survey. Results: From 216 patients presenting for Lyme evaluation, 19 participants enrolled with 84% completing the study (N\u2009=\u200916). Baseline PROMIS GH scores consisting of general Physical Health (GPH) and general Mental Health (GMH) scores were lower in the study population than in the general U.S. population.

A total of 129 patients with a physician-documented history of Lyme disease from three study sites in the northeast United States were studied. Seventy-eight were seropositive for IgG antibodies against Borrelia burgdorferi, and 51 were seronegative. Patients in each group were randomly assigned to receive IV ceftriaxone 2 g daily for 30 days followed by oral doxycycline 200 mg daily for 60 days or matching IV and oral placebos. Assessments were made at 90 and 180 days after treatment. Symptom severity was measured from the cognitive functioning, pain, and role functioning scales of the Medical Outcomes Study (MOS). Memory, attention, and executive functioning were assessed using objective tests. Mood was assessed using the Beck Depression Inventory and Minnesota Multiphasic Personality Inventory. There were no significant baseline differences between seropositive and seronegative groups. Both groups reported a high frequency of MOS symptoms, depression, and somatic complaints but had normal baseline neuropsychological test scores. The combined groups showed significant decreases in MOS symptoms, higher objective test scores, and improved mood between baseline and 90 days. However, there were no significant differences between those receiving antibiotics and placebo. Patients with post-treatment chronic Lyme disease who have symptoms but show no evidence of persisting Borrelia infection do not show objective evidence of cognitive impairment.

The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome."

A retrospective cohort analysis of medical and pharmacy claims derived from the Truven Health Market Scan Commercial Claims and Encounters Database assessed 90-day incidence rates of adverse events (AEs) associated with PLDS treatment (PLDS-Tx). Patients were diagnosed with PLDS \u22656 months after initial diagnosis and standard antibiotic treatment for Lyme disease. Comparison cohorts included intravenous (IV) PLDS-Tx with or without oral antibiotics; oral antibiotic-only PLDS-Tx; or neither. Composite AE incidence rates were higher for patients treated with IV or oral PLDS-Tx than for patients not receiving either treatment (18.7%, 16.8%, and 13.4%, respectively; P = .019). Significant between-group differences in AE incidence rates were noted for electrolyte imbalance (4.0%, 1.5%, and 0.7%, respectively; P = .001) and infection (14.0%, 12.7%, and 9.3%; P = .006). Infection prevalence increased by 22.0% in the IV treatment group and 17.7% in the oral group. Incidence rates for all-cause and AE-related hospital stays and emergency department visits were higher for treated than nontreated patients, particularly when treatment was IV (all P < .01). Of IV-treated patients, 7.3% experienced an incident all-cause inpatient stay and 11.3% an incident all-cause emergency department visit, compared with, respectively, 2.2% and 3.4% of those treated with oral antibiotics and 0.9% and 1.9% of nontreated patients. Use of IV therapies or oral antibiotics for PLDS was associated with increased patient morbidity within 90 days."

Current medical consensus, based on existing clinical trials and guidelines, indicates that there is no validated \"cure\" for this syndrome. Antibiotic re-treatment has consistently failed to demonstrate clinical efficacy and carries significant risk. Treatment approaches are currently limited to symptom management, multidisciplinary rehabilitation, and emerging investigation into immunomodulatory, neuromodulatory, and lifestyle interventions.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a complex, multifactorial, and controversial clinical entity. Research confirms that standard antibiotic regimens for the initial Lyme infection are effective; however, a subset of patients subsequently develops persistent, debilitating symptoms. Rigorous clinical investigations have demonstrated that prolonged or repeated antibiotic therapy provides no benefit for PTLDS patients and is associated with adverse events. The pathophysiology is currently the subject of extensive study, with hypotheses ranging from persistent inflammation and immune dysregulation to neuroinflammation, though no singular, quantifiable biomarker has yet been established to confirm the diagnosis or guide a curative therapy. Consequently, management is currently focused on mitigating symptoms rather than achieving a definitive cure.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Long-term antibiotic therapy for PTLDS is not recommended due to consistent failures in randomized controlled trials and the potential for serious adverse effects.\n*   Recent PET imaging studies suggest that PTLDS patients may exhibit cerebral glial activation, indicating a potential persistent neuroinflammatory process.\n*   Approximately 20% of patients with disseminated or late Lyme disease may develop PTLDS.\n*   There is a recognized disconnect between patient-reported (subjective) dysautonomia and objective clinical autonomic testing.\n*   A significant percentage of patients referred to specialty clinics for suspected Lyme disease are ultimately diagnosed with alternative conditions, highlighting the risks of misdiagnosis.\n*   Immunologic factors, such as the presence of myositis autoantibodies, have been identified in a subset of PTLDS patients.\n*   Online yoga and other mindfulness-based interventions have shown preliminary success in improving pain and cognitive performance in PTLDS cohorts.\n*   The economic burden of PTLDS is significant, with patients experiencing high healthcare utilization rates and notable impacts on employment status.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Treatment is predominantly management-focused rather than curative.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nWhile antibiotic therapy is highly effective for initial *Borrelia burgdorferi* infection, a subset of patients (10-20%) develop persistent symptoms (PTLDS). Evidence-based medicine currently lacks a curative regimen for PTLDS, with major clinical guidelines advising against long-term antibiotic or immunomodulatory therapy due to lack of demonstrated efficacy and risk of adverse effects. Management emphasizes a multidisciplinary, symptom-focused approach.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe management of Post-Treatment Lyme Disease Syndrome (PTLDS) remains one of the most significant challenges in modern infectious disease medicine. While clinical guidelines confirm that antibiotics are essential for the primary treatment of Lyme borreliosis, they do not resolve the post-infectious manifestations observed in a significant minority of patients. As stated in the provided literature, \"Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects.\" The persistence of symptoms such as fatigue, cognitive impairment, and diffuse pain, often lasting beyond six months, suggests a complex pathology that is not simply a residual infection.

Based on the provided literature, there is no clinical evidence to support the existence of a \"cure\" for this syndrome. Controlled trials consistently indicate that prolonged antibiotic therapy provides no sustained benefit and carries significant risks of adverse events. Current management strategies emphasize symptom relief and multidisciplinary, non-pharmacological support.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a medically contested entity due to the absence of well-defined diagnostic biomarkers and the lack of evidence for persistent active infection. Multiple systematic reviews and randomized controlled trials (RCTs) have demonstrated that prolonged courses of antibiotics, often used for \"chronic Lyme disease,\" are ineffective for PTLDS and frequently result in serious adverse outcomes, such as infections and hospitalizations. \n\nThe literature underscores that the pathophysiology of PTLDS is poorly understood, with hypotheses ranging from autoimmune responses, permanent tissue damage, or allostatic load to the existence of nonviable antigenic debris. Given the lack of a causative agent or a consistent pathomechanism, no definitive \"cure\" exists in current clinical practice. Instead, research has shifted toward feasibility studies for non-pharmacological interventions, such as online yoga and Ayurveda-based mind-body practices, which may assist in managing symptom burden and improving quality of life, rather than eliminating the syndrome itself.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Evidence suggests that prolonged antibiotic therapy does not address the core symptoms of PTLDS and can introduce significant morbidity.\n*   Diagnosis of PTLDS is purely clinical, as no quantifiable laboratory methods exist to verify the syndrome's presence or resolution.\n*   Some patients diagnosed with \"chronic Lyme disease\" may actually be suffering from other, distinct conditions such as fibromyalgia, chronic fatigue syndrome, or depression.\n*   The prevalence of PTLDS is estimated to occur in approximately 10\u201320% of adequately treated Lyme patients.\n*   Emerging research into MSA/MAA autoantibodies in PTLDS patients points toward potential immune dysregulation as a pathogenetic factor rather than persistent infection.\n*   Yoga and mind-body interventions have demonstrated feasibility and potential in reducing pain and cognitive impairment in PTLDS cohorts.\n*   Misattribution of focal infections (like tonsillitis) as \"chronic Lyme disease\" is a documented source of diagnostic error.\n*   The medical literature explicitly cautions against the use of central venous catheters for long-term antibiotic administration due to risks of serious infections, such as *Mycobacterium goodii*.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In fact, it can be dangerous and lead to serious health problems [ID: 37784031, 29672671].\n*   **The focus is on managing life:** Since there is no quick fix, doctors focus on \"symptom management.\" This means finding ways to help you feel better in your daily life, such as through physical therapy, psychological support, or even gentle lifestyle changes like online yoga, which has shown some promise in reducing pain and improving daily function [ID: 41796643, 37844086, 27000820].\n*   **It is not always \"Lyme\":** Sometimes, people who think they have chronic Lyme disease actually have other conditions that share similar symptoms, like fibromyalgia or chronic fatigue syndrome [ID: 33735220, 40330647].\n\nIn short, the medical community currently views this as a complex condition where the best path forward is multidisciplinary care\u2014focusing on treating the symptoms you have right now rather than searching for an antibiotic \"cure\" that hasn't been proven to work [ID: 41314472, 40733058].",

Current medical consensus, based on existing clinical trials and guidelines, indicates that there is no validated \"cure\" for this syndrome. Antibiotic re-treatment has consistently failed to demonstrate clinical efficacy and carries significant risk. Treatment approaches are currently limited to symptom management, multidisciplinary rehabilitation, and emerging investigation into immunomodulatory, neuromodulatory, and lifestyle interventions.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a complex, multifactorial, and controversial clinical entity. Research confirms that standard antibiotic regimens for the initial Lyme infection are effective; however, a subset of patients subsequently develops persistent, debilitating symptoms. Rigorous clinical investigations have demonstrated that prolonged or repeated antibiotic therapy provides no benefit for PTLDS patients and is associated with adverse events. The pathophysiology is currently the subject of extensive study, with hypotheses ranging from persistent inflammation and immune dysregulation to neuroinflammation, though no singular, quantifiable biomarker has yet been established to confirm the diagnosis or guide a curative therapy. Consequently, management is currently focused on mitigating symptoms rather than achieving a definitive cure.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Long-term antibiotic therapy for PTLDS is not recommended due to consistent failures in randomized controlled trials and the potential for serious adverse effects.\n*   Recent PET imaging studies suggest that PTLDS patients may exhibit cerebral glial activation, indicating a potential persistent neuroinflammatory process.\n*   Approximately 20% of patients with disseminated or late Lyme disease may develop PTLDS.\n*   There is a recognized disconnect between patient-reported (subjective) dysautonomia and objective clinical autonomic testing.\n*   A significant percentage of patients referred to specialty clinics for suspected Lyme disease are ultimately diagnosed with alternative conditions, highlighting the risks of misdiagnosis.\n*   Immunologic factors, such as the presence of myositis autoantibodies, have been identified in a subset of PTLDS patients.\n*   Online yoga and other mindfulness-based interventions have shown preliminary success in improving pain and cognitive performance in PTLDS cohorts.\n*   The economic burden of PTLDS is significant, with patients experiencing high healthcare utilization rates and notable impacts on employment status.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Treatment is predominantly management-focused rather than curative.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nWhile antibiotic therapy is highly effective for initial *Borrelia burgdorferi* infection, a subset of patients (10-20%) develop persistent symptoms (PTLDS). Evidence-based medicine currently lacks a curative regimen for PTLDS, with major clinical guidelines advising against long-term antibiotic or immunomodulatory therapy due to lack of demonstrated efficacy and risk of adverse effects. Management emphasizes a multidisciplinary, symptom-focused approach.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe management of Post-Treatment Lyme Disease Syndrome (PTLDS) remains one of the most significant challenges in modern infectious disease medicine. While clinical guidelines confirm that antibiotics are essential for the primary treatment of Lyme borreliosis, they do not resolve the post-infectious manifestations observed in a significant minority of patients. As stated in the provided literature, \"Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects.\" The persistence of symptoms such as fatigue, cognitive impairment, and diffuse pain, often lasting beyond six months, suggests a complex pathology that is not simply a residual infection. Consequently, clinical strategies have shifted toward symptom management, including physical rehabilitation and psychological support.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Current diagnostic markers are non-existent; PTLDS is currently diagnosed clinically based on symptoms following treated infection.\n*   \"Chronic Lyme disease\" is often used in popular media, but professional bodies like the IDSA prefer the term PTLDS to describe this specific post-treatment sequela.\n*   Persistent symptoms are not consistently linked to current/ongoing spirochete presence, leading to hypotheses regarding autoimmune responses or tissue damage.\n*   Symptoms of PTLDS share high phenotypic similarity with other infection-associated chronic conditions (IACCI) such as Long COVID and ME/CFS.\n*   There is a significant psychological and economic burden, with patients often \"wandering from specialty to specialty\" in search of diagnosis and relief.\n*   Therapeutic trials, including those for TPE (therapeutic plasma exchange), have largely failed in unselected populations, suggesting the future of treatment lies in biomarker-guided patient stratification.\n*   Recent research has begun to investigate mind-body interventions, such as online yoga, which have shown feasibility and benefits for symptom burden management.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Based on the provided literature, there is no clinical evidence to support the existence of a \"cure\" for this syndrome. Controlled trials consistently indicate that prolonged antibiotic therapy provides no sustained benefit and carries significant risks of adverse events. Current management strategies emphasize symptom relief and multidisciplinary, non-pharmacological support.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a medically contested entity due to the absence of well-defined diagnostic biomarkers and the lack of evidence for persistent active infection. Multiple systematic reviews and randomized controlled trials (RCTs) have demonstrated that prolonged courses of antibiotics, often used for \"chronic Lyme disease,\" are ineffective for PTLDS and frequently result in serious adverse outcomes, such as infections and hospitalizations. \n\nThe literature underscores that the pathophysiology of PTLDS is poorly understood, with hypotheses ranging from autoimmune responses, permanent tissue damage, or allostatic load to the existence of nonviable antigenic debris. Given the lack of a causative agent or a consistent pathomechanism, no definitive \"cure\" exists in current clinical practice. Instead, research has shifted toward feasibility studies for non-pharmacological interventions, such as online yoga and Ayurveda-based mind-body practices, which may assist in managing symptom burden and improving quality of life, rather than eliminating the syndrome itself.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Evidence suggests that prolonged antibiotic therapy does not address the core symptoms of PTLDS and can introduce significant morbidity.\n*   Diagnosis of PTLDS is purely clinical, as no quantifiable laboratory methods exist to verify the syndrome's presence or resolution.\n*   Some patients diagnosed with \"chronic Lyme disease\" may actually be suffering from other, distinct conditions such as fibromyalgia, chronic fatigue syndrome, or depression.\n*   The prevalence of PTLDS is estimated to occur in approximately 10\u201320% of adequately treated Lyme patients.\n*   Emerging research into MSA/MAA autoantibodies in PTLDS patients points toward potential immune dysregulation as a pathogenetic factor rather than persistent infection.\n*   Yoga and mind-body interventions have demonstrated feasibility and potential in reducing pain and cognitive impairment in PTLDS cohorts.\n*   Misattribution of focal infections (like tonsillitis) as \"chronic Lyme disease\" is a documented source of diagnostic error.\n*   The medical literature explicitly cautions against the use of central venous catheters for long-term antibiotic administration due to risks of serious infections, such as *Mycobacterium goodii*.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

nicht auf eine antibiotische Therapie ansprechen.\nWe found no differences between the groups in either cognitive function, cortical thickness or brain volumes.\nThis review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS.\nEligible studies show no statistically significant difference between antibiotics and placebo regarding quality of life, cognition and depression.\nAt this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024.\nAfter 6 months, the number of patients experiencing symptoms was significantly lower in the Pycnogenol\u00ae group compared to the control group across all symptoms (P<0.05).\nThese findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and

Begin with a clear Yes or No. Is the synthesis 100% veridical with the validated quotes? Your job is to look for hallucinations by the AI, not to judge the science itself. All claims must be at least non-implausible based on the evidence set provided. Do NOT penalize for the user question or rewritten claim since these are meta items. Only evaluate the AI evaluation of the literature and that the AI followed instructions without hallucinating. List and justify your judgements. Do not use markdown.\nAssistant: Yes. The synthesis is 100% veridical with the provided validated quotes and adheres to the instructions provided. \n\nJustification:\n\n1. Accuracy of Attribution: Every significant claim made in the synthesis is directly supported by the list of validated quotes. For example, the claim that antibiotic re-treatment lacks efficacy and carries risks is supported by multiple sources (ID: 41314472, ID: 27407225, ID: 29672671). The assertion that there is no validated cure is consistent with the provided literature characterizing the condition as clinically diagnosed without quantifiable biomarkers (ID: 39161484).\n\n2. Absence of Hallucinations: I have cross-referenced the claims regarding specific interventions (such as yoga and Pycnogenol) and the failure of clinical trials (such as RituxME and TPE) against the provided citations. All referenced studies are present in the provided context, and their findings are accurately summarized within the synthesis.\n\n3. Adherence to Instructions: The response maintains the required tone, avoids robotic formatting when asked about the AI's identity (though this specific query focused on verification), and adheres strictly to the provided source material as required by the RAG Amnesia and Zero-Tolerance Gate protocols. \n\n4. Logical Integrity: The AI correctly identifies the meta-nature of the user question and the rewritten claim, focusing its evaluation on the internal consistency of the evidentiary summary. No claims were made that fall outside the bounds of the provided literature; all statements remain within the realm of the evidence set.\n\n\n=============================\nUser Request: ANSWER IN THIS LANGUAGE --->>> Answer in English only.

When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences."

Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor.

Persisting symptoms are often termed post-Lyme disease syndrome, of which etiology is not clearly understood. The aim of this study was to investigate cognitive function, possible structural changes in brain regions and level of fatigue. We have not found previous studies on neuroborreliosis that use standardized neuropsychological tests and MRI with advanced image processing to investigate if there are subtle regional changes in cortical thickness and brain volumes after treatment. We examined 68 patients treated for neuroborreliosis 6\u00a0months earlier and 66 healthy controls, with a comprehensive neuropsychological test protocol, quantitative structural MRI analysis of the brain and Fatigue Severity Scale. We found no differences between the groups in either cognitive function, cortical thickness or brain volumes. The patients had higher score on Fatigue Severity Scale 3.8 vs. 2.9 (p\u2009=\u20090.001), and more patients (25.4%) than controls (5%) had severe fatigue (p\u2009=\u20090.002), but neither mean score nor proportion of patients with severe fatigue differed from findings in the general Norwegian population. The prognosis regarding cognitive function, brain MRI findings and fatigue after adequately treated neuroborreliosis is favorable."

PTLDS (post treatment Lyme disease syndrome) is a controversial topic. It has been described as a source of overdiagnosis and off-label treatment. This review aims to describe the diagnostic errors and adverse events associated with the diagnosis and treatment of PTLDS. systematic review of the literature in the Medline and Cochrane Library databases, according to PRISMA criteria, including randomized clinical trials (RCT), observational studies, and case reports addressing diagnostic errors and adverse events published between January 2010 and November 2020 in English or French. Selection used a quadruple reading process on the basis of the titles and abstracts of the different articles, followed by a full reading. 17 studies were included: 1 RCT, 6 observational studies and 10 case reports. In the 6 observational studies, overdiagnosis rates were very high, ranging from 80 to 100%. The new diagnoses were often psychiatric, rheumatological and neurological. Disorders with somatic symptoms were often cited. Diagnostic delays were identified for cancers and frontoparietal dementia. In the RCT and observational studies, prolonged anti-infective treatments were also responsible for adverse events, with emergency room visits and/or hospitalization. The most common adverse events were diarrhea, sometimes with Clostridium difficile colitis, electrolyte abnormalities, sepsis, bacterial and fungal infections, and anaphylactic reactions. This review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS. It emphasizes the ethical imperative of the \"primum non nocere\" principle, which underscores the importance of not causing harm to patients. Physicians should exercise caution in diagnosing PTLDS and consider the potential risks associated with off-label treatments."

No restrictions on case definitions, study types or specific interventions were applied to enable a comprehensive overview of the available literature. Risk of bias was assessed using the Cochrane risk of bias tools for randomized controlled trials. Certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach. Outcomes of interest were quality of life, fatigue, depression and cognition as well as adverse events. After screening 1274 records, eight eligible randomized controlled trials were included. Heterogeneity was observed regarding inclusion criteria, intervention, length of treatment and outcome measures. For efficacy outcomes, results are presented narratively due to heterogeneity. Eligible studies show no statistically significant difference between antibiotics and placebo regarding quality of life, cognition and depression. Results for fatigue were inconsistent whilst studies with low risk of bias showed no statistically significant difference between antibiotics and placebo. Meta-analysis of safety outcomes showed statistically significantly more adverse events for antibiotics compared to placebo. Available literature on treatment of PTLDs is heterogeneous, but overall shows evidence of no effect of antibiotics regarding quality of life, depression, cognition and fatigue whilst showing more adverse events. Patients with suspected PTLDs should not be treated with antibiotics."

These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues."

There is currently no specific treatment for this condition. The subjects were divided into two groups: one group received 150 mg/day of Pycnogenol\u00ae alongside standard management, while the control group received only standard management. The observation period lasted for six months. Forty subjects with history of Lyme Disease and persistent symptoms completed the study: 20 in the Pycnogenol\u00ae group, 20 in the control group. No side effects from the supplementation were observed. The tolerability was optimal as no supplemented subject had to stop management and compliance was optimal with 97% of the Pycnogenol\u00ae capsules correctly used. The two groups were comparable for sex, age distribution and for their main clinical findings and signs/symptoms at inclusion. During the study, corticosteroids at low dose were used on demand in 10% of subjects using Pycnogenol\u00ae and significantly more, in 45% of the control patients (P<0.05). After 6 months, the number of patients experiencing symptoms was significantly lower in the Pycnogenol\u00ae group compared to the control group across all symptoms (P<0.05). After 6 months, the intensity of all symptoms in the Pycnogenol\u00ae group, was significantly lower, according to the scores in comparison with the control group (P<0.05). Plasma oxidative stress was significantly reduced in subjects of the Pycnogenol\u00ae group (P<0.05) in comparison with controls. The improvement in plasma oxidative stress was seen in all subjects using Pycnogenol\u00ae. Knee effusion on ultrasound was seen in 12 subjects of the supplement group at inclusion and in 3 Pycnogenol\u00ae subjects at the end of the study in comparison with 12/20 subjects in the control group at inclusion and 8/20 at the end of the study. (P<0.05). Finally, ESR (Erythrocyte sedimentation rate, a global marker of inflammation) was significantly more reduced in the Pycnogenol\u00ae group by the end of the study compared to controls (P<0.05). In conclusion, the present registry study showed that Pycnogenol\u00ae intake for 6 months in patients with persistent symptoms of Lyme disease can help relieve the main symptoms by reducing inflammation and oxidative stress. Pycnogenol's anti-inflammatory and antioxidant double activity may help safely and effectively controlling the chronic inflammatory process."

Here, we evaluated in silico the predicted binding affinities of 192 HLA-II alleles with all 15-mer peptide sequences of five Borrelia burgdorferi proteins to identify peptides with strong binding affinity, as they would be the best candidates for antibody production in response to vaccination. We found the following: (a) 226 of the 1067 peptides tested (21.2%) were found to bind strongly to HLA-II molecules; (b) decorin-binding protein A had the greatest number of strongly binding peptides; and (c) 69 HLA-II alleles (primarily of the DRB1 gene) bound with strong affinity to peptides from Borrelia burgdorferi proteins. Finally, we tested for possible susceptibility to autoimmunity by any one of the 226 peptides above by searching for their occurrence in ~84,000 proteins of the human proteome and found overlap with only two 8-mer peptide sequences (embedded within the 226 15-mer peptides), neither of which was characterized by strong binding to HLA-I, suggesting a reduced likelihood of autoimmunity. These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety. The results of this computational study provide novel directions for future development of Lyme vaccines."

This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination."

In some patients, however, problems persist for a long time despite appropriate therapy. The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome."

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions."

It is unknown whether subjective dysautonomia obtained from autonomic questionnaires correlates with objective dysautonomia measured by quantitative autonomic testing. The objective of our study was to determine correlations between subjective and objective measures of dysautonomia. This was a retrospective cross-sectional study conducted at Brigham and Women's Faulkner Hospital Autonomic Laboratory between 2017 and 2023 evaluating the patients who completed autonomic testing. Analyses included validated autonomic questionnaires [Survey of Autonomic Symptoms (SAS), Composite Autonomic Symptom Score 31 (Compass-31)] and standardized autonomic tests (Valsalva maneuver, deep breathing, sudomotor, and tilt test). The autonomic testing results were graded by a Quantitative scale for grading of cardiovascular reflexes, sudomotor tests and skin biopsies (QASAT), and Composite Autonomic Severity Score (CASS). Autonomic testing, QASAT, CASS, and SAS were obtained in 2627 patients, and Compass-31 in 564 patients. The correlation was strong between subjective instruments (SAS vs. Compass-31, r\u2009=\u20090.74, p\u2009<\u20090.001) and between objective instruments (QASAT vs. CASS, r\u2009=\u20090.81, p\u2009<\u20090.001). There were no correlations between SAS and QASAT nor between Compass-31 and CASS.

The lack of correlation between subjective and objective instruments highlights the limitations of the commonly used questionnaires with some patients overestimating and some underestimating true autonomic deficit. The diagnosis-independent subjective-objective mismatch further signifies the unmet need for reliable screening surveys. Patients who overestimate the symptom burden may represent a population with idiosyncratic autonomic-like symptomatology, which needs further study. At this time, the use of autonomic questionnaires as a replacement of autonomic testing cannot be recommended."

We evaluated whether Swedish adults who met the criteria for post-treatment Lyme disease syndrome (PTLDS) exhibited characteristics distinguishable from adults who did not, but who displayed similar symptoms and disease course after suspected previous tick-bite infection (TBI). During 2015-2018, 255 patients-referred to the Centre for Vector-borne Infections, Uppsala University Hospital, Sweden with symptoms lasting longer than six months-were recruited. Of this group, 224 completed the study. Each patient was examined by an infectious disease specialist and, besides a full medical history, underwent a panel of blood and cerebrospinal fluid laboratory tests including hematological, biochemical, microbiological and immunological analyses, and the RAND-36 scale to measure quality of life. For analysis purposes, patients were divided into five subgroups, of which one represented PTLDS. According to serological results indicating TBI and documented/ reported objective signs of Lyme disease, 85 (38%) patients fulfilled the criteria for PTLDS and were compared with the other 139 (62%) serologically classified patients. In the PTLDS group, erythema chronicum migrans (ECM) was documented/reported in 86% of patients, previous neuroborreliosis in 15%, and acrodermatitis chronica atroficans (ACA) in 3.5%. However, there were no significant differences regarding symptoms, laboratory results or disease course between patients with PTLDS and those without laboratory evidence of Borrelia exposition. Most reported symptoms were fatigue-related (70%), musculoskeletal (79%), neurological (82%) and neurocognitive (57%). Tick bites were recalled by 74%. The RAND-36 score was significantly below that of the general Swedish population. Signs of immunological/inflammatory reactivity with myositis antibodies were detected in 20% of patients, fibrinogen levels were moderately increased in 21% and elevated rheumatoid factor in 6%. The PTLDS group did not differ exclusively in any respect from the other subgroups, which either lacked previously documented/reported evidence of borreliosis or even lacked detectable serological signs of exposure to Lyme disease. The results suggest that symptoms often categorized as Chronic-Lyme-Disease (CLD) in the general debate, cannot be uniquely linked to Lyme disease. However, approximately 20% of the total group of patients showed signs of autoimmunity. Further studies are needed to elucidate the underlying causes and mechanisms of PTLDS and there is reason to consider a multifactorial approach."

In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients. The most frequent neurological syndromes were radiculoneuritis (36.84%), bilateral facial palsy (13.56%), radiculoneuritis and bilateral facial palsy (10.52%) and multiple cranial mononeuropathy (10.52%), among others. 78.9% achieved a complete recovery, and 15.79% developed post-treatment Lyme disease syndrome.

This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs."

The aim of this exploratory study was to evaluate the feasibility of protein biomarker profiling as a diagnostic platform for this category of patients and to compare these results with similarly obtained results from a group of patients with acute neuroborreliosis. Two groups of patient cohorts (Cohort 1 and 2) were analyzed for biomarkers in serum and cerebrospinal fluid (CSF); the results were used for group-level comparison. Cohort 1 comprised 158 adult patients selected from 224 previously diagnosed patients, who between October 2015 and December 2018, after referral, were enrolled and structurally investigated based on defined inclusion criteria. They displayed similar lingering symptoms, with a duration of at least 6 months, after presumed previous tick-borne infection (TBI) and are fully described in a previously published study originating from the Center for Vector-borne Infections (CVI), Uppsala University Hospital, Sweden. Cohort 2, comprised 30 patients diagnosed at Uppsala University Hospital between 2016 and 2019 with laboratory-confirmed acute neuroborreliosis. Their proteomic results, based on serum and CSF analyses, were compared with the 158 patients in Cohort 1. The expression and the concentration of potential biomarkers in each patient's serum and CSF samples were measured based on two multiplex protein panels enabling simultaneous analysis of 92 inflammatory and neurology biomarkers. The PTLDS patient subgroup showed no nominally significant proteins compared to the other CVI patients in Cohort 1. However, CVI patients with signs of inflammation, which were evenly distributed in Cohort 1, showed 16 significantly (p <0.05) different proteins in both CSF and serum, but no association was seen with laboratory-confirmed exposure to Borrelia spp or other TBIs. When comparing the two cohorts, different protein profiles were observed, with 125/148 significantly different proteins in CSF and 93/174 in serum, in patients with laboratory confirmed acute neuroborreliosis, of which 6 in CSF and 6 in serum were significant at the p <0.001 level. In this first comprehensive inflammatory and neurological biomarker profile study no differences in biomarker profiles were detected between patients with PTLDS and patients with similar persisting symptoms but who did not meet the PTLDS criteria, regardless of whether laboratory verified previous exposure to Borrelia or other TBI's were present. However, the expressed markers differed from those found in patients with confirmed acute neuroborreliosis, which does not support the view that PTLDS reflects an ongoing Borrelia infection. Further studies are needed to understand and assess the usefulness of biosignatures of patients with PTLDS before they can be applied in a clinical setting."

Brain PET scan of patients with PTLDS have demonstrated likely glial activation indicating persistent neuroinflammatory processes. It is possible that unresolved bacterial remnants can continue to cause neuroinflammation. In previous studies, we have shown that non-viable Borrelia burgdorferi can induce neuroinflammation and apoptosis in an oligodendrocyte cell line. In this follow-up study, we analyze the effect of sonicated remnants of B. burgdorferi on primary rhesus frontal cortex (FC) and dorsal root ganglion (DRG) explants. Five FC and three DRG tissue fragments from rhesus macaques were exposed to sonicated B. burgdorferi and analyzed for 26 inflammatory mediators. Live bacteria and medium alone served as positive and negative control, respectively. Tissues were also analyzed for cell types mediating inflammation and overall apoptotic changes. Non-viable B. burgdorferi induced significant levels of several inflammatory mediators in both FC and DRG, similar to live bacteria. However, the levels induced by non-viable B. burgdorferi was often (several fold) higher than those induced by live ones, especially for IL-6, CXCL8 and CCL2. This effect was also more profound in the FC than in the DRG. Although the levels often differed, both live and dead fragments induced the same mediators, with significant overlap between FC and DRG. In the FC, immunohistochemical staining for several inflammatory mediators showed the presence of multiple mediators in astrocytes, followed by microglia and oligodendrocytes, in response to bacterial remnants. Staining was also seen in endothelial cells. In the DRG, chemokine/cytokine staining was predominantly seen in S100 positive (glial) cells. B. burgdorferi remnants also induced significant levels of apoptosis in both the FC and DRG. Apoptosis was confined to S100\u2009+\u2009cells in the DRG while distinct neuronal apoptosis was also detected in most FC tissues in response to sonicated bacteria. Non-viable B. burgdorferi can continue to be neuropathogenic to both CNS and PNS tissues with effects likely more profound in the former. Persistence of remnant-induced neuroinflammatory processes can lead to long term health consequences."

Current medical consensus, based on existing clinical trials and guidelines, indicates that there is no validated \"cure\" for this syndrome. Antibiotic re-treatment has consistently failed to demonstrate clinical efficacy and carries significant risk. Treatment approaches are currently limited to symptom management, multidisciplinary rehabilitation, and emerging investigation into immunomodulatory, neuromodulatory, and lifestyle interventions.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a complex, multifactorial, and controversial clinical entity. Research confirms that standard antibiotic regimens for the initial Lyme infection are effective; however, a subset of patients subsequently develops persistent, debilitating symptoms. Rigorous clinical investigations have demonstrated that prolonged or repeated antibiotic therapy provides no benefit for PTLDS patients and is associated with adverse events. The pathophysiology is currently the subject of extensive study, with hypotheses ranging from persistent inflammation and immune dysregulation to neuroinflammation, though no singular, quantifiable biomarker has yet been established to confirm the diagnosis or guide a curative therapy. Consequently, management is currently focused on mitigating symptoms rather than achieving a definitive cure.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Long-term antibiotic therapy for PTLDS is not recommended due to consistent failures in randomized controlled trials and the potential for serious adverse effects.\n*   Recent PET imaging studies suggest that PTLDS patients may exhibit cerebral glial activation, indicating a potential persistent neuroinflammatory process.\n*   Approximately 20% of patients with disseminated or late Lyme disease may develop PTLDS.\n*   There is a recognized disconnect between patient-reported (subjective) dysautonomia and objective clinical autonomic testing.\n*   A significant percentage of patients referred to specialty clinics for suspected Lyme disease are ultimately diagnosed with alternative conditions, highlighting the risks of misdiagnosis.\n*   Immunologic factors, such as the presence of myositis autoantibodies, have been identified in a subset of PTLDS patients.\n*   Online yoga and other mindfulness-based interventions have shown preliminary success in improving pain and cognitive performance in PTLDS cohorts.\n*   The economic burden of PTLDS is significant, with patients experiencing high healthcare utilization rates and notable impacts on employment status.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions.\n\nID: 42148664\nTitle: Designing studies for post-treatment Lyme disease and other infection-associated chronic illnesses.\nAbstract: Infection-associated chronic illnesses (IACIs) encompass a spectrum of poorly understood syndromes often marked by significant neurologic and multisystem symptoms following an infectious event. This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs.\n\nID: 41826406\nTitle: Evaluation of immunoreactive epitopes in the sera and cerebrospinal fluid of patients with post-treatment Lyme disease syndrome.\nAbstract: While most patients fully recover after treatment for Lyme disease with recommended antibiotic regimens, some report non-specific symptoms after treatment. When these symptoms are unexplained by other conditions and persist for \u2265\u20096 months, this condition is called post-treatment Lyme disease symptoms or syndrome (PTLDS). The pathogenesis of PTLDS is unknown and no specific diagnostic biomarkers have been identified. In this study, we used a high-density peptide array to examine antibody responses to >\u200960 primary antigens of B. burgdorferi from a cohort of patients diagnosed with PTLDS and recovered patients with similar Lyme disease manifestations. Using matched serum and cerebrospinal fluid (CSF), we mapped the primary reactive B. burgdorferi epitopes associated with PTLDS. We found that VlsE had a greater antibody response within the PTLDS cohort than recovered patients. The reactivity to OspC-specific epitopes revealed a predominance of antibodies to OspC type K and A in the PTLDS cohort. However, the major immunodominant epitopes were similar in PTLDS and recovered patients, and we were unable to identify specific diagnostic targets for PTLDS. We found a more robust reactivity in the serum over CSF and did not identify antigenic regions that were specifically associated with the infection of the central nervous system.\n\nID: 41796643\nTitle: Feasibility and preliminary efficacy of an online yoga program for managing symptoms of post-treatment lyme disease syndrome.\nAbstract: We evaluated the feasibility and efficacy of a 12-week synchronous online yoga program for managing post-treatment Lyme disease syndrome (PTLDS) symptoms, focusing on pain, physical functioning, and cognitive performance. Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms.\n\nID: 41570190\nTitle: Nonspecific Symptoms Attributable to Lyme Disease in High-Incidence Areas, United States, 2017-2021.\nAbstract: For some patients who have Lyme disease (LD), nonspecific symptoms can persist after treatment and impair quality of life. Estimating the frequency and duration of such symptoms is challenging. Using commercial insurance claims data from 2017-2021 for enrollees residing in states where LD is common, we identified 24,503 case-patients with LD and matched them (1:5) with 122,095 control-patients with other diagnoses by demographics, medical service date, and inpatient/outpatient setting. We compared relative frequencies of diagnosis codes for pain, fatigue, and cognitive difficulties between case-patients and control-patients in the year after diagnosis. Those symptom codes occurred 5.0% more frequently among case-patients than among control-patients and comprised \u00bb11.0% of the total symptom codes among case-patients. Symptom code frequency among case-patients declined significantly in the 6-12 months after LD diagnosis and reached levels similar to control-patients by the end of the year, with the exception of fatigue.\n\nID: 41314472\nTitle: Guidelines for Lyme borreliosis: post-treatment Lyme disease syndrome (PTLDS).\nAbstract: Persistent symptoms following appropriate treatment of confirmed Lyme borreliosis (LB) require a systematic clinical reassessment. The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences.\n\nID: 41195425\nTitle: Guidelines for diagnosis and treatment in neurology - Lyme neuroborreliosis.\nAbstract: Lyme disease is the most common tick-borne infectious disease in Europe. Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor. Im Rahmen eines systematischen Reviews zur Therapie des sogenannten Post-Treatment Lyme Disease Syndrome (PTLDS) zeigte sich, dass die untersuchten Parameter Lebensqualit\u00e4t, Fatigue, Depression und Kognition nicht auf eine antibiotische Therapie ansprechen. F\u00fcr die Wirksamkeit anderer Therapieverfahren fanden sich keine aussagekr\u00e4ftigen Studien.\n\nID: 40985958\nTitle: Evidence-Based Clinical Effectiveness of Kundalini Yoga: Systematic Review of RCTs Across Multiple Health Conditions.\nAbstract: Kundalini Yoga (KY) integrates breathwork, meditation, dynamic movement, and chanting, and has gained recognition as a therapeutic intervention. Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes. KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions. However, larger, standardized RCTs with active comparators, biomarkers, and longer follow-up are needed.

There is currently no specific treatment for this condition. The subjects were divided into two groups: one group received 150 mg/day of Pycnogenol\u00ae alongside standard management, while the control group received only standard management. The observation period lasted for six months. Forty subjects with history of Lyme Disease and persistent symptoms completed the study: 20 in the Pycnogenol\u00ae group, 20 in the control group. No side effects from the supplementation were observed. The tolerability was optimal as no supplemented subject had to stop management and compliance was optimal with 97% of the Pycnogenol\u00ae capsules correctly used. The two groups were comparable for sex, age distribution and for their main clinical findings and signs/symptoms at inclusion. During the study, corticosteroids at low dose were used on demand in 10% of subjects using Pycnogenol\u00ae and significantly more, in 45% of the control patients (P<0.05). After 6 months, the number of patients experiencing symptoms was significantly lower in the Pycnogenol\u00ae group compared to the control group across all symptoms (P<0.05). After 6 months, the intensity of all symptoms in the Pycnogenol\u00ae group, was significantly lower, according to the scores in comparison with the control group (P<0.05). Plasma oxidative stress was significantly reduced in subjects of the Pycnogenol\u00ae group (P<0.05) in comparison with controls. The improvement in plasma oxidative stress was seen in all subjects using Pycnogenol\u00ae. Knee effusion on ultrasound was seen in 12 subjects of the supplement group at inclusion and in 3 Pycnogenol\u00ae subjects at the end of the study in comparison with 12/20 subjects in the control group at inclusion and 8/20 at the end of the study. (P<0.05). Finally, ESR (Erythrocyte sedimentation rate, a global marker of inflammation) was significantly more reduced in the Pycnogenol\u00ae group by the end of the study compared to controls (P<0.05). In conclusion, the present registry study showed that Pycnogenol\u00ae intake for 6 months in patients with persistent symptoms of Lyme disease can help relieve the main symptoms by reducing inflammation and oxidative stress. Pycnogenol's anti-inflammatory and antioxidant double activity may help safely and effectively controlling the chronic inflammatory process.\n\nID: 39345262\nTitle: Current and emerging approaches for eliminating Borrelia burgdorferi and alleviating persistent Lyme disease symptoms.\nAbstract: Lyme disease is the most prevalent tick-borne infection caused by Borrelia burgdorferi bacteria in North America. Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated \u223c10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection.\n\nID: 39199993\nTitle: Biomarker-Based Analysis of Pain in Patients with Tick-Borne Infections before and after Antibiotic Treatment.\nAbstract: Tick-borne illnesses (TBIs), especially those caused by Borrelia, are increasingly prevalent worldwide. These diseases progress through stages of initial localization, early spread, and late dissemination. The final stage often leads to post-treatment Lyme disease syndrome (PTLDS) or chronic Lyme disease (CLD), characterized by persistent and non-specific multisystem symptoms affecting multiple systems, lasting over six months after antibiotic therapy. PTLDS significantly reduces functional ability, with 82-96% of patients experiencing pain, including arthritis, arthralgia, and myalgia. Inflammatory markers like CRP and TNF-alpha indicate ongoing inflammation, but the link between chronic pain and other biomarkers is underexplored. This study examined the relationship between pain and biomarkers in TBI patients from an Irish hospital and their response to antibiotic treatment. Pain ratings significantly decreased after antibiotic treatment, with median pain scores dropping from 7 to 5 (U = 27215.50, p < 0.001). This suggests a persistent infection responsive to antibiotics. Age and gender did not influence pain ratings before and after treatment. The study found correlations between pain ratings and biomarkers such as transferrin, CD4%, platelets, and neutrophils. However, variations in these biomarkers did not significantly predict pain changes when considering biomarkers outside the study. These findings imply that included biomarkers do not directly predict pain changes, possibly indicating allostatic load in symptom variability among long-term TBI patients. The study emphasizes the need for appropriate antibiotic treatment for TBIs, highlighting human rights issues related to withholding pain relief.\n\nID: 39161484\nTitle: What Makes It Tick: Exploring the Mechanisms of Post-treatment Lyme Disease Syndrome.\nAbstract: Post-treatment Lyme disease syndrome (PTLDS), which may also be referred to incorrectly as \"chronic Lyme disease,\" is defined by the Infectious Diseases Society of America (IDSA) as the presence of fatigue, pain, and/or cognitive complaints with the functional impact that persists for more than six months after completing treatment for Lyme disease (LD). These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues.\n\nID: 38752040\nTitle: Neuropsychiatric Manifestations and Cognitive Decline in Patients With Long-Standing Lyme Disease: A Scoping Review.\nAbstract: Lyme disease (LD), or Lyme borreliosis, is a vector-borne disease that is caused by the transmission of the bacterium Borrelia burgdorferi through a tick bite. The symptoms of LD can persist in individuals chronically, even after the treatment and resolution of the initial infection. These symptoms include various neuropsychiatric manifestations and cognitive decline. The purpose of this review was to report the neuropsychiatric manifestations, cognitive decline, and effects of a delayed diagnosis on symptom severity in patients with long-standing LD (LSLD). A scoping review was conducted utilizing the electronic databases Embase, Ovid Medical Literature Analysis and Retrieval System Online (MEDLINE), and Web of Science. A total of 744 articles were retrieved and considered for inclusion. After a rigorous screening process, 10 articles that met the inclusion criteria for this review were included (i.e., reported neuropsychiatric manifestations and cognitive decline in patients with LSLD and the effects of a delayed diagnosis). Neuropsychiatric manifestations in the patients consisted of suicidal ideation, homicidal tendencies, extreme anger, depressive symptoms, aggression, and anxiety. Cognitive symptoms included dysfunctions in working memory, verbal learning/memory, non-verbal learning/memory, alertness, visuoconstructive, and frontal executive functioning. A delayed LD diagnosis increased symptom severity in most patients. The findings of this review indicate that neuropsychiatric and cognitive symptoms tend to present for a chronic period, even after disease recovery. Although researchers have established a link between a delayed LD diagnosis and increased symptom severity, LSLD is often an overlooked diagnosis in patients with neuropsychiatric symptoms and cognitive decline. More research is needed to compare the time to diagnosis and symptom severity in patients with LSLD.\n\nID: 38613155\nTitle: A prospective study of patients with post treatment Lyme disease syndrome treated with modified VFEM energy.\nAbstract: We previously demonstrated a possible therapeutic benefit of VFEM (variable frequency electromagnetic energy) technology for the treatment of Post Treatment Lyme Disease Syndrome (PTLDS) or Chronic Lyme Disease (CLD). As a result, we prospectively enrolled 10 patients, all having significant debility, to determine to what extent we could improve their quality of life. Eight patients completed the 10 treatments. All eight patients had a significant improvement in quality of life within a 4-month time frame. VFEM is a stand-alone modality that appears to demonstrate a significant improvement in quality of life in PTLDS or CLD with little or no risk or side effects of treatment.\n\nID: 38606630\nTitle: Treatment of post-treatment Lyme disease symptoms-a systematic review.\nAbstract: Residual symptoms after treatment of Lyme disease, sometimes called post-treatment Lyme disease symptoms (PTLDs), are a matter of ongoing controversy. To guide treatment recommendations, a systematic review was performed of the available literature on specific treatment for PTLDs. A systematic literature search of MEDLINE and CENTRAL was performed. No restrictions on case definitions, study types or specific interventions were applied to enable a comprehensive overview of the available literature. Risk of bias was assessed using the Cochrane risk of bias tools for randomized controlled trials. Certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach. Outcomes of interest were quality of life, fatigue, depression and cognition as well as adverse events. After screening 1274 records, eight eligible randomized controlled trials were included. Heterogeneity was observed regarding inclusion criteria, intervention, length of treatment and outcome measures. For efficacy outcomes, results are presented narratively due to heterogeneity. Eligible studies show no statistically significant difference between antibiotics and placebo regarding quality of life, cognition and depression. Results for fatigue were inconsistent whilst studies with low risk of bias showed no statistically significant difference between antibiotics and placebo. Meta-analysis of safety outcomes showed statistically significantly more adverse events for antibiotics compared to placebo. Available literature on treatment of PTLDs is heterogeneous, but overall shows evidence of no effect of antibiotics regarding quality of life, depression, cognition and fatigue whilst showing more adverse events. Patients with suspected PTLDs should not be treated with antibiotics.\n\nID: 37692614\nTitle: Lyme Disease and Post-treatment Lyme Disease Syndrome: Current and Developing Treatment Options.\nAbstract: Lyme disease and its treatment implications have become an ever-increasing area of concern within the United States\u00a0related to the markedly increased prevalence of infection within the last two decades. The presentation, pathophysiology, and epidemiology of Lyme disease have been well studied, and thus treatments for this disease are widely available. While the treatment of its early and late stages is relatively simple with 10-14 day and four-week courses of doxycycline, respectively, the main problem rests in the understanding of the etiology and pathology of post-treatment Lyme disease syndrome (PTLDS). With the time of symptoms onsetting approximately six months after treatment and potentially lasting indefinitely, this syndrome's effect on patients' quality of life could be devastating. Searching on PubMed, Google Scholar, MEDLINE, and ScienceDirect\u00a0using keywords including Lyme disease, PTLDS, doxycycline, erythema migrans, azlocillin, and treatment, the authors have tried to make clear the different aspects. The authors have reviewed and discussed clinical studies of Lyme disease and its treatments/potential therapeutics as well as PTLDS and its sparse treatments/potential therapeutics.\n\nID: 37293310\nTitle: Lyme disease and the pursuit of a clinical cure.\nAbstract: Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most common vector-borne illness in the United States. Many aspects of the disease are still topics of controversy within the scientific and medical communities. One particular point of debate is the etiology behind antibiotic treatment failure of a significant portion (10-30%) of Lyme disease patients. The condition in which patients with Lyme disease continue to experience a variety of symptoms months to years after the recommended antibiotic treatment is most recently referred to in the literature as post treatment Lyme disease syndrome (PTLDS) or just simply post treatment Lyme disease (PTLD). The most commonly proposed mechanisms behind treatment failure include host autoimmune responses, long-term sequelae from the initial Borrelia infection, and persistence of the spirochete. The aims of this review will focus on the in vitro, in vivo, and clinical evidence that either validates or challenges these mechanisms, particularly with regard to the role of the immune response in disease and resolution of the infection. Next generation treatments and research into identifying biomarkers to predict treatment responses and outcomes for Lyme disease patients are also discussed. It is essential that definitions and guidelines for Lyme disease evolve with the research to translate diagnostic and therapeutic advances to patient care.\n\nID: 36972275\nTitle: Cost of illness in patients with post-treatment Lyme disease syndrome in Belgium.\nAbstract: A proportion of patients with Lyme borreliosis (LB) report long-term persisting signs and symptoms, even after recommended antibiotic treatment, which is termed post-treatment Lyme disease syndrome (PTLDS). Consensus on guidance regarding diagnosis and treatment is currently lacking. Consequently, patients suffer and are left searching for answers, negatively impacting their quality of life and healthcare expenditure. Yet, health economic data on PTLDS remain scarce. The aim of this article is therefore to assess the cost-of-illness related to PTLDS, including the patient perspective. PTLDS patients (N\u2009=\u2009187) with confirmed diagnosis of LB were recruited by a patient organization. Patients completed a self-reported questionnaire on LB-related healthcare utilization, absence from work and unemployment. Unit costs (reference year 2018) were obtained from national databases and published literature. Mean costs and uncertainty intervals were calculated via bootstrapping. Data were extrapolated to the Belgian population. Generalized linear models were used to determine associated covariates with total direct costs and out-of-pocket expenditures. Mean annual direct costs amounted to \u20ac4618 (95% CI \u20ac4070-5152), of which 49.5% were out-of-pocket expenditures. Mean annual indirect costs amounted to \u20ac36\u00a0081 (\u20ac31\u00a0312-40\u00a0923). Direct and indirect costs at the population level were estimated at \u20ac19.4 and 151.5 million, respectively. A sickness or disability benefit as source of income was associated with higher direct and out-of-pocket costs. The economic burden associated with PTLDS on patients and society is substantial, with patients consuming large amounts of non-reimbursed healthcare resources. Guidance on adequate diagnosis and treatment of PTLDS is needed.\n\nID: 36380166\nTitle: Assessment of cognitive function, structural brain changes and fatigue 6\u00a0months after treatment of neuroborreliosis.\nAbstract: Complete recovery after adequately treated neuroborreliosis is common, but studies report that some patients experience persistent symptoms like self-reported cognitive problems and fatigue. Persisting symptoms are often termed post-Lyme disease syndrome, of which etiology is not clearly understood. The aim of this study was to investigate cognitive function, possible structural changes in brain regions and level of fatigue. We have not found previous studies on neuroborreliosis that use standardized neuropsychological tests and MRI with advanced image processing to investigate if there are subtle regional changes in cortical thickness and brain volumes after treatment. We examined 68 patients treated for neuroborreliosis 6\u00a0months earlier and 66 healthy controls, with a comprehensive neuropsychological test protocol, quantitative structural MRI analysis of the brain and Fatigue Severity Scale. We found no differences between the groups in either cognitive function, cortical thickness or brain volumes. The patients had higher score on Fatigue Severity Scale 3.8 vs. 2.9 (p\u2009=\u20090.001), and more patients (25.4%) than controls (5%) had severe fatigue (p\u2009=\u20090.002), but neither mean score nor proportion of patients with severe fatigue differed from findings in the general Norwegian population. The prognosis regarding cognitive function, brain MRI findings and fatigue after adequately treated neuroborreliosis is favorable.\n\nID: 36327322\nTitle: Protein biomarker profiles in serum and CSF in 158 patients with PTLDS or persistent symptoms after presumed tick-bite exposure compared to those in patients with confirmed acute neuroborreliosis.\nAbstract: Current diagnostics for patients with lingering symptoms categorized as post-treatment Lyme disease syndrome (PTLDS) have their limitations and may be difficult to interpret. The aim of this exploratory study was to evaluate the feasibility of protein biomarker profiling as a diagnostic platform for this category of patients and to compare these results with similarly obtained results from a group of patients with acute neuroborreliosis. Two groups of patient cohorts (Cohort 1 and 2) were analyzed for biomarkers in serum and cerebrospinal fluid (CSF); the results were used for group-level comparison. Cohort 1 comprised 158 adult patients selected from 224 previously diagnosed patients, who between October 2015 and December 2018, after referral, were enrolled and structurally investigated based on defined inclusion criteria. They displayed similar lingering symptoms, with a duration of at least 6 months, after presumed previous tick-borne infection (TBI) and are fully described in a previously published study originating from the Center for Vector-borne Infections (CVI), Uppsala University Hospital, Sweden. Cohort 2, comprised 30 patients diagnosed at Uppsala University Hospital between 2016 and 2019 with laboratory-confirmed acute neuroborreliosis. Their proteomic results, based on serum and CSF analyses, were compared with the 158 patients in Cohort 1. The expression and the concentration of potential biomarkers in each patient's serum and CSF samples were measured based on two multiplex protein panels enabling simultaneous analysis of 92 inflammatory and neurology biomarkers. The PTLDS patient subgroup showed no nominally significant proteins compared to the other CVI patients in Cohort 1. However, CVI patients with signs of inflammation, which were evenly distributed in Cohort 1, showed 16 significantly (p <0.05) different proteins in both CSF and serum, but no association was seen with laboratory-confirmed exposure to Borrelia spp or other TBIs. When comparing the two cohorts, different protein profiles were observed, with 125/148 significantly different proteins in CSF and 93/174 in serum, in patients with laboratory confirmed acute neuroborreliosis, of which 6 in CSF and 6 in serum were significant at the p <0.001 level. In this first comprehensive inflammatory and neurological biomarker profile study no differences in biomarker profiles were detected between patients with PTLDS and patients with similar persisting symptoms but who did not meet the PTLDS criteria, regardless of whether laboratory verified previous exposure to Borrelia or other TBI's were present. However, the expressed markers differed from those found in patients with confirmed acute neuroborreliosis, which does not support the view that PTLDS reflects an ongoing Borrelia infection. Further studies are needed to understand and assess the usefulness of biosignatures of patients with PTLDS before they can be applied in a clinical setting.\n\nID: 35066160\nTitle: Risk of post-treatment Lyme disease in patients with ideally-treated early Lyme disease: A prospective cohort study.\nAbstract: Post-treatment Lyme disease (PTLD) is characterized by patient-reported symptoms after treatment for Borrelia burgdorferi infection. The primary aim of this study was to assess whether participants with a history of Lyme disease (LD) would be more likely to meet criteria for PTLD than those without a history of LD. We conducted a longitudinal, prospective study among 234 participants with and 49 participants without prior LD. All completed survey metrics for fatigue, pain, sleep, depression, and quality of life. An operationalized PTLD definition was applied to both cohorts, and the distributions of clinical outcomes and symptoms were examined. In total, 13\u00b77% of participants with a history of prior LD met criteria for PTLD compared with 4\u00b71% of those without a history of prior LD. Participants with prior LD were approximately 5\u00b728 times as likely to meet PTLD criteria compared with those without prior LD (p\u00a0=\u00a00\u00b7042) and had 8-15 times as high odds of reporting moderate or severe fatigue and muscle pain (p\u00a0=\u00a00\u00b7002, 0\u00b7047, respectively). Risk of meeting PTLD criteria was also independently increased among females and those with higher exposure to previous traumatic life events. Participants ideally diagnosed and treated for prior LD reported more symptoms on standardized surveys and were more likely to meet criteria for PTLD than those without prior LD.\n\nID: 34785530\nTitle: Estimating the population health burden of Lyme disease in Ontario, Canada: a microsimulation modelling approach.\nAbstract: If untreated, Lyme disease can lead to long-term sequelae and post-treatment Lyme disease syndrome (PTLDS), resulting in reduced health-related quality of life. The objective of this study was to develop a microsimulation model to estimate the population-level health burden of Lyme disease in Ontario, Canada. We developed a Lyme disease history model using microsimulation, simulating 100 000 people (mean age 37.6 yr, 51% female) from 2017 in Ontario over a lifetime risk of infection and time horizon. We extracted the sensitivity and specificity of the 2-tier testing recommended by the Canadian Public Health Laboratory Network, probabilities and health state utility values from the published literature and health administrative data. Our reported outcomes from our stochastic analysis include diagnosed cases of Lyme disease (stratified by stage), undiagnosed infections, sequelae, individuals with PTLDS and quality-adjusted life-years (QALYs) lost. Our model estimated 333 (95% confidence interval [CI] 329-337) infections over the lifetime of 100 000 simulated people (mean age 37.6 yr, 51% female), with 92% (95% CI 91%-93%) of infections diagnosed. Of those 308 people with Lyme Disease diagnoses, 67 (95% CI 65-69) developed sequelae (e.g., arthritic, cardiac, neurologic sequelae), and 34 (95% CI 33-35) developed PTLDS. Lyme disease resulted in a loss of 84.5 QALYs (95% CI 82.9-86.2) over the lifetime of the simulated cohort. Sensitivity and scenario analysis showed that increasing incidence rates of Lyme disease, potential underreporting, duration of PTLDS and quality of life (health state utility) associated with PTLDS had the greatest impact on health burden. Lyme disease contributes considerable health burden in terms of QALYs lost. Our analysis provides evidence to understand the disease burden and lays the foundation to assess the cost-effectiveness of pharmaceutical and nonpharmaceutical interventions.\n\nID: 34659931\nTitle: Post-Treatment Lyme Disease Syndrome: Need for Diagnosis and Treatment.\nAbstract: With the continued surge in Lyme disease cases, post-treatment Lyme disease syndrome (PTLDS) is becoming a more pressing health concern. The aim of this review is to identify comprehensive treatment strategies for PTLDS patients. Unfortunately, universal guidelines for diagnosing and treating PTLDS do not currently exist. Consequently, physicians cannot adequately address concerns of possible PTLDS patients. Patients are left suffering and searching for answers, and their activities of daily living and quality of life are adversely impacted. This review highlights that PTLDS clinical trials have focused mainly on treatment with antibiotics, yielding challenging results that lack consistency in inclusion criteria across trials. It will remain exceedingly difficult to extrapolate the outcomes of such studies if a standard for PTLDS diagnosis is not well-established. By focusing on treatment trials rather than establishing diagnostic criteria, research in this field ignores a critical step in investigating PTLDS. The first significant step is to create comprehensive guidelines for the diagnosis of PTLDS, which can generate uniformity and validate PTLDS treatment trials.\n\nID: 34582513\nTitle: Characterizing Post-treatment Lyme Disease Syndrome: A Mixed Methods Study of Patients at a Lyme Disease Clinic in Rhode Island.\nAbstract: Mixed quantitative and qualitative research methods may be useful for characterizing the experiences of patients with post-treatment Lyme disease syndrome. 15 participants completed demographic and screening questions, surveys assessing quality of life, fatigue, pain, cognitive functioning, and other patient- reported outcomes, a semi-structured in-depth interview, and consented to a Lyme-related medical chart review. Participants reported mild to moderate symptoms and functional impairments on patient-reported outcome surveys and in-depth interviews. Participants reported on a number of management strategies that they found more or less effective in managing their symptoms. Participants endorsed the need for better clinical assessment of symptom patterns over time, greater Lyme-related education for providers, more holistic approaches to diagnosis and care, and the desire to participate in Lyme-focused support groups. Overall, participants desired a more holistic approach to diagnosis, symptom assessment, and symptom management. Recommendations for future research and clinical considerations are discussed.\n\nID: 33735220\nTitle: A comprehensive clinical and laboratory evaluation of 224 patients with persistent symptoms attributed to presumed tick-bite exposure.\nAbstract: Persistent symptoms attributed to presumed tick-bite exposure constitute an unresolved medical controversy. We evaluated whether Swedish adults who met the criteria for post-treatment Lyme disease syndrome (PTLDS) exhibited characteristics distinguishable from adults who did not, but who displayed similar symptoms and disease course after suspected previous tick-bite infection (TBI). During 2015-2018, 255 patients-referred to the Centre for Vector-borne Infections, Uppsala University Hospital, Sweden with symptoms lasting longer than six months-were recruited. Of this group, 224 completed the study. Each patient was examined by an infectious disease specialist and, besides a full medical history, underwent a panel of blood and cerebrospinal fluid laboratory tests including hematological, biochemical, microbiological and immunological analyses, and the RAND-36 scale to measure quality of life. For analysis purposes, patients were divided into five subgroups, of which one represented PTLDS. According to serological results indicating TBI and documented/ reported objective signs of Lyme disease, 85 (38%) patients fulfilled the criteria for PTLDS and were compared with the other 139 (62%) serologically classified patients. In the PTLDS group, erythema chronicum migrans (ECM) was documented/reported in 86% of patients, previous neuroborreliosis in 15%, and acrodermatitis chronica atroficans (ACA) in 3.5%. However, there were no significant differences regarding symptoms, laboratory results or disease course between patients with PTLDS and those without laboratory evidence of Borrelia exposition. Most reported symptoms were fatigue-related (70%), musculoskeletal (79%), neurological (82%) and neurocognitive (57%). Tick bites were recalled by 74%. The RAND-36 score was significantly below that of the general Swedish population. Signs of immunological/inflammatory reactivity with myositis antibodies were detected in 20% of patients, fibrinogen levels were moderately increased in 21% and elevated rheumatoid factor in 6%. The PTLDS group did not differ exclusively in any respect from the other subgroups, which either lacked previously documented/reported evidence of borreliosis or even lacked detectable serological signs of exposure to Lyme disease. The results suggest that symptoms often categorized as Chronic-Lyme-Disease (CLD) in the general debate, cannot be uniquely linked to Lyme disease. However, approximately 20% of the total group of patients showed signs of autoimmunity. Further studies are needed to elucidate the underlying causes and mechanisms of PTLDS and there is reason to consider a multifactorial approach.\n\nID: 33168903\nTitle: Evaluation of pathogen specific urinary peptides in tick-borne illnesses.\nAbstract: Mass spectrometry enhanced by nanotechnology can achieve previously unattainable sensitivity for characterizing urinary pathogen-derived peptides. We utilized mass spectrometry enhanced by affinity hydrogel particles (analytical sensitivity\u2009=\u20092.5\u00a0pg/mL) to study tick pathogen-specific proteins shed in the urine of patients with (1) erythema migrans rash and acute symptoms, (2) post treatment Lyme disease syndrome (PTLDS), and (3) clinical suspicion of tick-borne illnesses (TBI). Targeted pathogens were Borrelia, Babesia, Anaplasma, Rickettsia, Ehrlichia, Bartonella, Francisella, Powassan virus, tick-borne encephalitis virus, and Colorado tick fever virus. Specificity was defined by 100% amino acid sequence identity with tick-borne pathogen proteins, evolutionary taxonomic verification for related pathogens, and no identity with human or other organisms. Using a cut off of two pathogen peptides, 9/10 acute Lyme Borreliosis patients resulted positive, while we identified zero false positive in 250 controls. Two or more pathogen peptides were identified in 40% of samples from PTLDS and TBI patients (categories 2 and 3 above, n\u2009=\u200959/148). Collectively, 279 distinct unique tick-borne pathogen derived peptides were identified. The number of pathogen specific peptides was directly correlated with presence or absence of symptoms reported by patients (ordinal regression pseudo-R2\u2009=\u20090.392, p\u2009=\u20090.010). Enhanced mass spectrometry is a new tool for studying tick-borne pathogen infections.\n\nID: 33105645\nTitle: Efficacy of Double-Dose Dapsone Combination Therapy in the Treatment of Chronic Lyme Disease/Post-Treatment Lyme Disease Syndrome (PTLDS) and Associated Co-infections: A Report of Three Cases and Retrospective Chart Review.\nAbstract: Three patients with multi-year histories of relapsing and remitting Lyme disease and associated co-infections despite extended antibiotic therapy were each given double-dose dapsone combination therapy (DDD CT) for a total of 7-8 weeks. At the completion of therapy, all three patients' major Lyme symptoms remained in remission for a period of 25-30 months. A retrospective chart review of 37 additional patients undergoing DDD CT therapy (40 patients in total) was also performed, which demonstrated tick-borne symptom improvements in 98% of patients, with 45% remaining in remission for 1 year or longer. In conclusion, double-dose dapsone therapy could represent a novel and effective anti-infective strategy in chronic Lyme disease/ post-treatment Lyme disease syndrome (PTLDS), especially in those individuals who have failed regular dose dapsone combination therapy (DDS CT) or standard antibiotic protocols. A randomized, blinded, placebo-controlled trial is warranted to evaluate the efficacy of DDD CT in those individuals with chronic Lyme disease/PTLDS.\n\nID: 31867334\nTitle: The General Symptom Questionnaire-30 (GSQ-30): A Brief Measure of Multi-System Symptom Burden in Lyme Disease.\nAbstract: Introduction: The multi-system symptoms accompanying acute and post-treatment Lyme disease syndrome pose a challenge for time-limited assessment. The General Symptom Questionnaire (GSQ-30) was developed to fill the need for a brief patient-reported measure of multi-system symptom burden. In this study we assess the psychometric properties and sensitivity to change of the GSQ-30. Materials and Methods: 342 adult participants comprised 4 diagnostic groups: Lyme disease (post-treatment Lyme disease syndrome, n = 124; erythema migrans, n = 94); depression, n = 36; traumatic brain injury, n = 51; healthy, n = 37. Participants were recruited from clinical research facilities in Massachusetts, Maryland, and New York. Validation measures for the GSQ-30 included the Patient Health Questionnaire-4 for depression and anxiety, visual analog scales for fatigue and pain, the Sheehan Disability Scale for functional impairment, and one global health question. To assess sensitivity to change, 53 patients with erythema migrans completed the GSQ-30 before treatment and 6 months after 3 weeks of treatment with doxycycline. Results: The GSQ-30 demonstrated excellent internal consistency (Cronbach \u03b1 = 0.95). The factor structure reflects four core domains: pain/fatigue, neuropsychiatric, neurologic, and viral-like symptoms. Symptom burden was significantly associated with depression (r s = 0.60), anxiety (r s = 0.55), pain (r s = 0.75), fatigue (r s = 0.77), functional impairment (r s = 0.79), and general health (r s = -0.58). The GSQ-30 detected significant change in symptom burden before and after antibiotic therapy; this change correlated with change in functional impairment. The GSQ-30 total score significantly differed for erythema migrans vs. three other groups (post-treatment Lyme disease syndrome, depression, healthy controls). The GSQ-30 total scores for traumatic brain injury and depression were not significantly different from post-treatment Lyme disease syndrome. Conclusions and Relevance: The GSQ-30 is a valid and reliable instrument to assess symptom burden among patients with acute and post-treatment Lyme disease syndrome and is sensitive in the detection of change after treatment among patients with erythema migrans. The GSQ-30 should prove useful in clinical and research settings to assess multi-system symptom burden and to monitor change over time. The GSQ-30 may also prove useful in future precision medicine studies as a clinical measure to correlate with disease-relevant biomarkers.\n\nID: 30765287\nTitle: Management of patients presenting with generalized musculoskeletal pain and a suspicion of Lyme disease.\nAbstract: Lyme disease is caused by bacteria of the B.\u00a0burgdorferi sensu lato complex, and can give polymorphic clinical manifestations that can affect several organs such as the skin, the central nervous system, or the joints. In recent years, patients' associations and physicians have been supporting the hypothesis that this infection would manifest as chronic generalized musculoskeletal pain symptoms, named \"chronic Lyme disease\". Fibromyalgia is a clinical presentation characterized by chronic generalized musculoskeletal pain with a major impact on quality of life and social and psychological functioning. We analyzed existing literature data on pain syndromes associated with Lyme disease (post-treatment Lyme disease syndrome) or tick bites (polymorphic symptoms after a tick bite). We also analyzed existing data on the diagnosis, pathophysiology, and treatment of fibromyalgia. Our review shows that post-treatment Lyme disease syndrome has characteristics very close to post-infectious fibromyalgia. On the other hand, patients presenting for Lyme disease screening because of chronic generalized musculoskeletal pain symptoms after a tick bite should also be screened for fibromyalgia to allow appropriate management. Antibiotics are not recommended here.\n\nID: 30736992\nTitle: Functional neuroimaging in patients presenting with somatoform disorders: A model for investigating persisting symptoms after tick bites and post-treatment Lyme disease syndrome?\nAbstract: Approximately 10% of patients presenting with Lyme disease experience fatigue, musculoskeletal pain, concentration disorders, or short-term memory deficits in the six months following treatment. This entity has been defined as post-Lyme disease syndrome or post-treatment Lyme disease syndrome. The pathophysiology of this syndrome is unknown, but neither persistence of the bacterium nor effectiveness of antibiotics are currently reported in the literature. The French High Council for Public Health (French acronym HCSP) has recently defined a new entity called \"persistent polymorphic symptoms after a tick bite\" allowing for designing studies to better understand these subjective presentations, for which objective biomarkers are currently lacking. This entity encompasses patients experiencing fatigue and generalized pain in the months following a tick bite and can be associated with several subjective symptoms with major impact on the quality of life. In the field of somatoform disorders, this article reviews functional neuroimaging studies in patients presenting with subjective complaints and discusses potential clinical implications for persisting symptoms after tick bites and post-treatment Lyme disease syndrome.\n\nID: 41972549\nTitle: In Silico-Identified Peptides of Five Borrelia burgdorferi Proteins Binding with High Affinity to Human Leukocyte Antigen (HLA) Class II Alleles.\nAbstract: To date, Lyme vaccine development has largely overlooked the vaccinee's human leukocyte antigen (HLA) genetic makeup on which antibody production critically depends. Here, we evaluated in silico the predicted binding affinities of 192 HLA-II alleles with all 15-mer peptide sequences of five Borrelia burgdorferi proteins to identify peptides with strong binding affinity, as they would be the best candidates for antibody production in response to vaccination. We found the following: (a) 226 of the 1067 peptides tested (21.2%) were found to bind strongly to HLA-II molecules; (b) decorin-binding protein A had the greatest number of strongly binding peptides; and (c) 69 HLA-II alleles (primarily of the DRB1 gene) bound with strong affinity to peptides from Borrelia burgdorferi proteins. Finally, we tested for possible susceptibility to autoimmunity by any one of the 226 peptides above by searching for their occurrence in ~84,000 proteins of the human proteome and found overlap with only two 8-mer peptide sequences (embedded within the 226 15-mer peptides), neither of which was characterized by strong binding to HLA-I, suggesting a reduced likelihood of autoimmunity. These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety. The results of this computational study provide novel directions for future development of Lyme vaccines.\n\nID: 41653328\nTitle: Sex and menopause-based differences in presentation of early Lyme disease: A prospective cohort study.\nAbstract: Although prior research has established sex and menopausal status-based differences in immune response, susceptibility, and severity to a variety of pathogens, their relevance in early Lyme disease is understudied. We examined the clinical and serologic presentation of patients with early Lyme disease, stratified first by sex then by menopausal status. We also explored the hypothesis that males would present with more severe early Lyme disease. In this prospective cohort study from the Mid-Atlantic US, 243 adult, antibiotic-na\u00efve patients were enrolled with a diagnostic erythema migrans rash present. Demographic, physical exam, symptom, laboratory, and two-tier serology data were collected at a baseline, and a post-treatment visit 3 weeks later. Lyme disease severity was operationalized through six indicators: rash size, number of acute symptoms, dermatologic dissemination, positive serology, liver function elevation, and elevated neutrophil-lymphocyte ratio. Unadjusted group comparisons and multivariate regression adjusting for potential confounders were used to assess difference. In logistic models adjusted for age, Lyme disease duration, systemic steroid use, and co-morbid thyroid disease, males had higher odds of testing two-tier positive (OR\u2009=\u20091.77 [1.03, 3.04], p\u2009=\u20090.039). This difference was more pronounced between males and pre-menopausal females (OR\u2009=\u20092.93 [1.26-6.79], p\u2009=\u20090.012) and no significant difference was found comparing males to post-menopausal females. In ordinal logistic models with Lyme disease severity as the outcome adjusted for age and Lyme disease duration, males had higher odds of being in a higher disease severity score category (OR\u2009=\u20091.94 [1.20,3.15], p\u2009=\u20090.028); again, particularly in comparison to pre-menopausal females (OR\u2009=\u20092.26 [1.13,4.58], p\u2009=\u20090.044). Heart palpitations (p\u2009=\u20090.023), vomiting (p\u2009=\u20090.007), and photophobia (p\u2009=\u20090.057) trended towards higher reporting among females, while sleep difficulty (p\u2009=\u20090.010) was higher among males. No differences were found on non-dermatologic components of the physical exam.\u00a0We found sex and menopausal status to be relevant in accounting for variability in two-tier serologic status and severity of early Lyme disease in a well-characterized group of patients. Lower rates of seroreactivity among females is unexpected but may be consistent with lower acute severity of disease. Our clinical findings underscore the need for additional research to understand possible contributing biologic and/or social behavioral factors, as well as their impact on timely diagnosis and post-treatment conditions. Lyme disease is a bacterial infection obtained through a tick bite. The goal of this study was to look at whether male and female patients with early Lyme disease show up to the doctor with different signs of their disease in terms of the symptoms they report, their physical exams, and the results of their laboratory tests. We also examined whether females who had gone through menopause would be different on these factors compared to those who had not. We studied data from 243 adults (118 females and 125 males) with early Lyme disease before and after treatment. We found that at diagnosis, males were more likely to have a positive test and more obvious findings of severe disease, yet there were no differences in how long males and females had been sick. For both of these findings, the male group was more similar to females who had undergone menopause and was more different than females who had not. We found a small number of Lyme disease symptoms that were reported more frequently among females (heart palpitations, vomiting, eyes sensitive to light, neck pain, nausea) and two symptoms (sleep difficulty and irritability) reported more frequently among males. These findings suggest that sex and menopause status are important to consider in understanding early Lyme disease. More research is needed to determine the cause of these differences and their impact on time to diagnosis and risk of later conditions after treatment.\n\nID: 41421419\nTitle: Methemoglobinemia induced by dapsone, hydroxychloroquine, and rifampin combination for post-treatment Lyme disease syndrome: A case report.\nAbstract: A patient presented to the emergency department with drug-induced methemoglobinemia due to a combination of medications prescribed for post-treatment Lyme disease syndrome (PTLDS). This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination.\n\nID: 41136524\nTitle: HLA and pathogens in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and other post-infection conditions.\nAbstract: Viral infections have been widely implicated in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) pathogenesis. Recent evidence has also identified certain Human Leukocyte Antigen (HLA) alleles that are significantly associated with ME/CFS risk/protection. Here we tested the hypothesis that ME/CFS risk or protection conferred from those HLA alleles is associated with binding affinity to antigens of HHV viruses, a critical step in initiating the adaptive immune system response to foreign antigens. Specifically, we determined in silico the predicted binding affinity of two susceptibility alleles (C*07:04, DQB1*03:03) and two protective alleles (B*08:01, DPB1*02:01) to >\u200910,000 antigens of the 9 Human Herpes Viruses (HHV1, HHV2, HHV3, HHV4, HHV5, HHV6A, HHV6B, HHV7, HHV8) which have been implicated in the etiology of ME/CFS. We found that the binding affinity of all HHV antigens to the susceptibility alleles was significantly weaker than the binding affinity to the protective alleles (P\u2009<\u20090.001). In fact, none of the HHV antigens showed strong binding to the susceptibility alleles, in contrast to the strong bindings showed by the protective alleles. These findings are in keeping with the hypothesis that the effect of a putative HHV insult in contributing to ME/CFS is modulated by the host's HLA immunogenetic makeup. We speculate that strong HLA-antigen binding likely protects against ME/CFS via elimination of virus antigens; conversely, weak HLA-antigen binding may permit persistence of foreign antigens, contributing to ME/CFS and other chronic conditions. Finally, with respect to the latter, we determined the binding affinities to the 4 HLA alleles above to pathogens causing two chronic diseases with very similar symptomatology to ME/CFS, namely Long COVID and post-treatment Lyme disease syndrome (PTLDS). We found that the 2 ME/CFS susceptibility HLA alleles above had very weak binding with SARS-CoV-2 virus glycoprotein (involved in Long COVID) and 5 proteins of Borrelia burgdorferi (involved in PTLDS), in contrast to the ME/CFS protective alleles that showed strong bindings. These findings support the hypothesis that ME/CFS, long COVID and PTLDS are caused by persistent pathogenic antigens that could not be eliminated due to inadequate protection by the patient's HLA makeup.\n\nID: 40703523\nTitle: Aberrant T-cell phenotypes in a cohort of patients with post-treatment Lyme disease.\nAbstract: Post-treatment Lyme Disease (PTLD) is a poorly understood complication of Borrelia burgdorferi infection with significant patient morbidity. Characterized by fatigue, generalized myalgias, and cognitive impairment, PTLD symptomatology closely resembles long COVID and other post-acute infection syndromes. While prior studies suggest immune dysregulation as a factor in PTLD pathogenesis, the mechanisms underlying its heterogeneous presentation and severity remain unclear. To associate symptom burden with discrete immune phenotypes, we applied factor analysis to self-reported symptom data from 272 PTLD patients to generate patient subgroups. We then immunophenotyped peripheral blood cells of these individuals and 28 healthy controls through 19-parameter flow cytometry and cytokine profiling to associate PTLD status and the newly defined subgroups with specific immune states. Our PTLD cohort had fewer circulating CXCR5+ CD4+ na\u00efve T cells relative to healthy controls (5.2% vs. 8.3%, Padj < 0.001). These cells were positively associated with musculoskeletal pain in PTLD participants, but not healthy controls. This and additional immunophenotypic alterations, including an increased prevalence of CXCR3+ CCR4- CCR6- CD8 T cells (43.1% vs. 25.7%, Padj < 0.01), permitted the creation of an elastic net classifier which identified PTLD with moderate efficacy (AUC 0.83). Measurement of cytokines did not reveal associations with PTLD and did not improve the performance of the model. While we could not identify immune features which distinguished all patient subgroups, we did observe a female-specific increase in central memory CD8 T cells restricted to one high-fatigue patient subgroup. Additionally, factor analysis revealed multiple associations between immune cell frequency and the severity of specific symptoms. Collectively, our findings add to growing evidence of immune dysfunction as a prominent feature of PTLD.\n\nID: 40662763\nTitle: Class and isotype of VlsE-specific antibody differentiates Lyme disease stage.\nAbstract: Establishment of immunoglobulin diversity is contingent on recombination that occurs both at the Fab and at the Fc regions of the immunoglobulin, and this process is time dependent. Based on this principle, we questioned whether Lyme disease stage can be distinguished by quantification of immunoglobulin class and IgG isotype specific to VlsE in serum from clinically characterized patients. We used an enzyme immunoassay to categorize serologic antibodies to VlsE antigen as well as machine-learning techniques to train and integrate multiple predictors to identify likely disease stage. We found that IgM/IgG3/IgG1/IgA1 was enriched in serum obtained in the earliest stages, whereas IgG3/IgG1/IgG4 was enriched in Lyme arthritis. IgG2 detection was unremarkable across all disease stages. Post-Treatment Lyme Disease Syndrome (PTLDS) serum was enriched in IgG3/IgG1/IgA1 but lacked IgM. The multivariable models showed better predictive accuracy than any single immunoglobulin model, with more than half of panels perfectly identified by random forest under cross validation (56%) vs a maximum of 38% for a model using IgG1 alone. The findings suggest a characteristic succession of VlsE-specific antibody switching between immunoglobulin class and IgG isotype as Lyme disease progresses from early to late stages. The data also suggest that immunoglobulin class and IgG isotyping are likely more helpful to distinguish early Lyme disease cases. Comprehensive evaluation of immunoglobulin class (M, G, A) and IgG isotypes (1/2/3/4) provides time-dependent pathogen-induced host response information to current Lyme disease antibody detection and may be useful for differentiation of disease stage. The order of switching between the immunoglobulin heavy chain (Fc) is time dependent, progressing from IgM/D to IgG3/IgG1/IgA1/IgG2/IgG4 and later to IgE/IgA2. In this study, we show that B. burgdorferi-VlsE-specific antibody switching proceeds in a predictable sequence between class (Ig M/G/A) and IgG isotype (IgG 1/2/3/4) as Lyme disease progresses from early to late stage and that antibody class and isotype may be more helpful to distinguish the early stages of Lyme disease. This study advances our understanding of the tempo and structure of the humoral immune response to B. burgdorferi and is applicable to the development of new diagnostic assays for Lyme disease.\n\nID: 39994562\nTitle: A comparison of genome-wide association analyses of persistent symptoms after Lyme disease, fibromyalgia, and myalgic encephalomyelitis - chronic fatigue syndrome.\nAbstract: Up to 20% of Lyme disease cases experience post-treatment Lyme disease syndrome (PTLDS). The biological basis for PTLDS is poorly understood and no evidence-based treatment has been identified. Genetic studies have the potential to elucidate PTLDS pathophysiology and identify treatment targets. We used electronic health record data (EHR) and genetic data from a linked biorepository to conduct a genome-wide association study (GWAS) for PTLDS among patients from a Pennsylvania health system. We evaluated the validity of the GWAS results in two separate conditions that have hypothesized overlapping pathophysiology, fibromyalgia and myalgic encephalomyelitis - chronic fatigue syndrome (ME/CFS). GWAS analyses were performed using logistic regression in SUGEN, assuming an additive genetic model, and adjusting for age, sex, array, and the first 10 principal components calculated from whole genome genotyping to adjust for ancestry, and accounting for relatedness including all 1st degree relationships. The functional mapping and annotation analysis (FUMA) tool was used to explore top findings from our GWAS. Among the 161,875 eligible MyCode participants with genotyping, there were 3,585 who met the criteria for treated Lyme disease. A subset of 695 (19.4%) of these patients met the criteria for PTLDS and the remaining 2890 were classified as controls. We identified two PTLDS loci that reached the suggestive significance threshold (P\u2009<\u20095\u2009\u00d7\u200910-\u20097), with lead variants rs77857587, near IRX1, and rs10833979, near GAS2. Our top index single nucleotide polymorphism (SNP), rs77857587, is in high linkage disequilibrium with a long-range protein quantitative locus SNP, rs111774530, for the MARC2 (Mitochondrial Amidoxime Reducing Component 2) protein. We identified 5,041 cases of fibromyalgia (150,599 controls) and 2,268 cases of ME/CFS (151,594 controls) among the MyCode participants. Neither of the two suggestively significant loci were associated with fibromyalgia or ME/CFS. We identified two PTLDS loci that reached a suggestive significance threshold. Our top index SNP is associated with the MARC2 protein, a protein that has been linked to multiple immune checkpoints. Further study is needed in a larger population to evaluate whether there is genetic evidence of the role of immune response in the occurrence of PTLDS.\n\nID: 39770289\nTitle: Examining Infant and Child Neurodevelopmental Outcomes After Lyme Disease During Pregnancy.\nAbstract: Lyme disease is the most common vector-borne disease in the United States. Recent environmental and socioecological changes have led to an increased incidence of Lyme and other tick-borne diseases, which enhances the urgency of identifying and mitigating adverse outcomes of Lyme disease exposure. Lyme disease during pregnancy, especially when untreated, may lead to adverse pregnancy and neonatal outcomes; however, long-term child outcomes following utero exposure to Lyme disease have not yet been systematically assessed. This concise review describes the current state of knowledge of Lyme disease as a congenital infection and the potential effects of in utero exposure to Lyme disease infection on the neurodevelopment of infants and children. We highlight the importance of distinguishing between acute Lyme disease and a chronic condition termed Post-Treatment Lyme Disease Syndrome, as the impacts of both conditions on the developing fetus and subsequent child development may differ. The importance of placental pathology for patients with acute or chronic symptoms of Lyme disease in pregnancy is explored. Future research aiming to understand and protect neurodevelopment after antenatal Lyme disease must carefully collect potentially confounding variables such as symptomatology and treatment, use clear and standard case definitions, and follow children into school-age and beyond.\n\nID: 38965869\nTitle: Retrograde and semantic amnesia in a case of post-treatment Lyme disease syndrome: did something lead to a psychogenic memory loss? A single-case study.\nAbstract: To describe a case of Post-Treatment Lyme Disease Syndrome (PTLDS) with an atypical cognitive profile. A 41-year-old PTLDS patient underwent comprehensive neuropsychological testing and psychological assessment. The patient exhibited impaired intensive attention but preserved selective attention. Executive functions were normal. Short-term and anterograde memory were intact, while retrograde and semantic memory were significantly impaired. The patient also experienced identity loss, specific phobias, dissociative symptoms, and depressed mood. Severe episodic-autobiographical and retrograde semantic amnesia was consistent with some reports of dissociative amnesia. Loss of identity and phobias were also highly suggestive of a psychogenic mechanism underlying amnesia.\n\nID: 38792737\nTitle: Combining Double-Dose and High-Dose Pulsed Dapsone Combination Therapy for Chronic Lyme Disease/Post-Treatment Lyme Disease Syndrome and Co-Infections, Including Bartonella: A Report of 3 Cases and a Literature Review.\nAbstract: Three patients with relapsing and remitting borreliosis, babesiosis, and bartonellosis, despite extended anti-infective therapy, were prescribed double-dose dapsone combination therapy (DDDCT) for 8 weeks, followed by one or several two-week courses of pulsed high-dose dapsone combination therapy (HDDCT). We discuss these patients' cases to illustrate three important variables required for long-term remission. First, diagnosing and treating active co-infections, including Babesia and Bartonella were important. Babesia required rotations of multiple anti-malarial drug combinations and herbal therapies, and Bartonella required one or several 6-day HDDCT pulses to achieve clinical remission. Second, all prior oral, intramuscular (IM), and/or intravenous (IV) antibiotics used for chronic Lyme disease (CLD)/post-treatment Lyme disease syndrome (PTLDS), irrespective of the length of administration, were inferior in efficacy to short-term pulsed biofilm/persister drug combination therapy i.e., dapsone, rifampin, methylene blue, and pyrazinamide, which improved resistant fatigue, pain, headaches, insomnia, and neuropsychiatric symptoms. Lastly, addressing multiple factors on the 16-point multiple systemic infectious disease syndrome (MSIDS) model was important in achieving remission. In conclusion, DDDCT with one or several 6-7-day pulses of HDDCT, while addressing abnormalities on the 16-point MSIDS map, could represent a novel effective clinical and anti-infective strategy in CLD/PTLDS and associated co-infections including Bartonella.\n\nID: 38390594\nTitle: Dysautonomia following Lyme disease: a key component of post-treatment Lyme disease syndrome?\nAbstract: Dysautonomia, or dysfunction of the autonomic nervous system (ANS), may occur following an infectious insult and can result in a variety of debilitating, widespread, and often poorly recognized symptoms. Dysautonomia is now widely accepted as a complication of COVID-19 and is an important component of Post-Acute Sequelae of COVID-19 (PASC or long COVID). PASC shares many overlapping clinical features with other infection-associated chronic illnesses including Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Post-Treatment Lyme Disease Syndrome (PTLDS), suggesting that they may share common underlying mechanisms including autonomic dysfunction. Despite the recognition of this complication of Lyme disease in the care of patients with PTLD, there has been a scarcity of research in this field and dysautonomia has not yet been established as a complication of Lyme disease in the medical literature. In this review, we discuss the evidence implicating Borrelia burgdorferi as a cause of dysautonomia and the related symptoms, propose potential pathogenic mechanisms given our knowledge of Lyme disease and mechanisms of PASC and ME/CFS, and discuss the diagnostic evaluation and treatments of dysautonomia. We also outline gaps in the literature and priorities for future research.\n\nID: 38291116\nTitle: Mismatch between subjective and objective dysautonomia.\nAbstract: Autonomic symptom questionnaires are frequently used to assess dysautonomia. It is unknown whether subjective dysautonomia obtained from autonomic questionnaires correlates with objective dysautonomia measured by quantitative autonomic testing. The objective of our study was to determine correlations between subjective and objective measures of dysautonomia. This was a retrospective cross-sectional study conducted at Brigham and Women's Faulkner Hospital Autonomic Laboratory between 2017 and 2023 evaluating the patients who completed autonomic testing. Analyses included validated autonomic questionnaires [Survey of Autonomic Symptoms (SAS), Composite Autonomic Symptom Score 31 (Compass-31)] and standardized autonomic tests (Valsalva maneuver, deep breathing, sudomotor, and tilt test). The autonomic testing results were graded by a Quantitative scale for grading of cardiovascular reflexes, sudomotor tests and skin biopsies (QASAT), and Composite Autonomic Severity Score (CASS). Autonomic testing, QASAT, CASS, and SAS were obtained in 2627 patients, and Compass-31 in 564 patients. The correlation was strong between subjective instruments (SAS vs. Compass-31, r\u2009=\u20090.74, p\u2009<\u20090.001) and between objective instruments (QASAT vs. CASS, r\u2009=\u20090.81, p\u2009<\u20090.001). There were no correlations between SAS and QASAT nor between Compass-31 and CASS. There continued to be no correlations between subjective and objective instruments for selected diagnoses (post-acute sequelae of COVID-19, n\u2009=\u200961; postural tachycardia syndrome, 211; peripheral autonomic neuropathy, 463; myalgic encephalomyelitis/chronic fatigue syndrome, 95; preload failure, 120; post-treatment Lyme disease syndrome, 163; hypermobile Ehlers-Danlos syndrome, 213; neurogenic orthostatic hypotension, 86; diabetes type II, 71, mast cell activation syndrome, 172; hereditary alpha tryptasemia, 45). The lack of correlation between subjective and objective instruments highlights the limitations of the commonly used questionnaires with some patients overestimating and some underestimating true autonomic deficit. The diagnosis-independent subjective-objective mismatch further signifies the unmet need for reliable screening surveys. Patients who overestimate the symptom burden may represent a population with idiosyncratic autonomic-like symptomatology, which needs further study. At this time, the use of autonomic questionnaires as a replacement of autonomic testing cannot be recommended.\n\nID: 37784031\nTitle: Diagnosis and treatment of \"chronic Lyme\": primum non nocere.\nAbstract: Approximately 10% of patients experience prolonged symptoms after Lyme disease. PTLDS (post treatment Lyme disease syndrome) is a controversial topic. It has been described as a source of overdiagnosis and off-label treatment. This review aims to describe the diagnostic errors and adverse events associated with the diagnosis and treatment of PTLDS. systematic review of the literature in the Medline and Cochrane Library databases, according to PRISMA criteria, including randomized clinical trials (RCT), observational studies, and case reports addressing diagnostic errors and adverse events published between January 2010 and November 2020 in English or French. Selection used a quadruple reading process on the basis of the titles and abstracts of the different articles, followed by a full reading. 17 studies were included: 1 RCT, 6 observational studies and 10 case reports. In the 6 observational studies, overdiagnosis rates were very high, ranging from 80 to 100%. The new diagnoses were often psychiatric, rheumatological and neurological. Disorders with somatic symptoms were often cited. Diagnostic delays were identified for cancers and frontoparietal dementia. In the RCT and observational studies, prolonged anti-infective treatments were also responsible for adverse events, with emergency room visits and/or hospitalization. The most common adverse events were diarrhea, sometimes with Clostridium difficile colitis, electrolyte abnormalities, sepsis, bacterial and fungal infections, and anaphylactic reactions. This review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS. It emphasizes the ethical imperative of the \"primum non nocere\" principle, which underscores the importance of not causing harm to patients. Physicians should exercise caution in diagnosing PTLDS and consider the potential risks associated with off-label treatments.\n\nID: 37764145\nTitle: Comparison of the Efficacy of Longer versus Shorter Pulsed High Dose Dapsone Combination Therapy in the Treatment of Chronic Lyme Disease/Post Treatment Lyme Disease Syndrome with Bartonellosis and Associated Coinfections.\nAbstract: Twenty-five patients with relapsing and remitting Borreliosis, Babesiosis, and bartonellosis despite extended anti-infective therapy were prescribed double-dose dapsone combination therapy (DDDCT), followed by one or several courses of High Dose Dapsone Combination Therapy (HDDCT). A retrospective chart review of these 25 patients undergoing DDDCT therapy and HDDCT demonstrated that 100% improved their tick-borne symptoms, and patients completing 6-7 day pulses of HDDCT had superior levels of improvement versus 4-day pulses if Bartonella was present. At the completion of treatment, 7/23 (30.5%) who completed 8 weeks of DDDCT followed by a 5-7 day pulse of HDDCT remained in remission for 3-9 months, and 3/23 patients (13%) who recently finished treatment were 1 \u00bd months in full remission. In conclusion, DDDCT followed by 6-7 day pulses of HDDCT could represent a novel, effective anti-infective strategy in chronic Lyme disease/Post Treatment Lyme Disease Syndrome (PTLDS) and associated co-infections, including Bartonella, especially in individuals who have failed standard antibiotic protocols.\n\nID: 37760644\nTitle: Neuropsychiatric Lyme Disease and Vagus Nerve Stimulation.\nAbstract: Lyme disease, the most common tick-borne disease in the United States, is caused by infection with the spirochete Borrelia burgdorferi. While most patients with acute Lyme disease recover completely if treated with antibiotics shortly after the onset of infection, approximately 10-30% experience post-treatment symptoms and 5-10% have residual symptoms with functional impairment (post-treatment Lyme disease syndrome or PTLDS). These patients typically experience pain, cognitive problems, and/or fatigue. This narrative review provides a broad overview of Lyme disease, focusing on neuropsychiatric manifestations and persistent symptoms. While the etiology of persistent symptoms remains incompletely understood, potential explanations include persistent infection, altered neural activation, and immune dysregulation. Widely recognized is that new treatment options are needed for people who have symptoms that persist despite prior antibiotic therapy. After a brief discussion of treatment approaches, the article focuses on vagus nerve stimulation (VNS), a neuromodulation approach that is FDA-approved for depression, epilepsy, and headache syndromes and has been reported to be helpful for other diseases characterized by inflammation and neural dysregulation. Transcutaneous VNS stimulates the external branch of the vagus nerve, is minimally invasive, and is well-tolerated in other conditions with few side effects. If well-controlled double-blinded studies demonstrate that transcutaneous auricular VNS helps patients with chronic syndromes such as persistent symptoms after Lyme disease, taVNS will be a welcome addition to the treatment options for these patients.\n\nID: 37653608\nTitle: Developing a Blood Cell-Based Diagnostic Test for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Using Peripheral Blood Mononuclear Cells.\nAbstract: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by debilitating fatigue that profoundly impacts patients' lives. Diagnosis of ME/CFS remains challenging, with most patients relying on self-report, questionnaires, and subjective measures to receive a diagnosis, and many never receiving a clear diagnosis at all. In this study, a single-cell Raman platform and artificial intelligence are utilized to analyze blood cells from 98 human subjects, including 61 ME/CFS patients of varying disease severity and 37 healthy and disease controls. These results demonstrate that Raman profiles of blood cells can distinguish between healthy individuals, disease controls, and ME/CFS patients with high accuracy (91%), and can further differentiate between mild, moderate, and severe ME/CFS patients (84%). Additionally, specific Raman peaks that correlate with ME/CFS phenotypes and have the potential to provide insights into biological changes and support the development of new therapeutics are identified. This study presents a promising approach for aiding in the diagnosis and management of ME/CFS and can be extended to other unexplained chronic diseases such as long COVID and post-treatment Lyme disease syndrome, which share many of the same symptoms as ME/CFS.\n\nID: 37109429\nTitle: Neuroborreliosis and Post-Treatment Lyme Disease Syndrome: Focus on Children.\nAbstract: Neuroborreliosis is a form of Lyme Borreliosis (LB) that affects various structures of the central and peripheral nervous system. Although most cases of LB can be cured with a course of antibiotics, some children can present prolonged symptoms, which may constitute post-treatment Lyme disease syndrome (PTLDS). The aim of our analysis was the long-term observation of children with NB and the determination of their risk of PTLDS. The clinical observation was supplemented by a laboratory study based on the assessment of the dynamics of anti-VlsE (variable major protein-like sequence, expressed) IgG antibodies in children with NB after antibiotic therapy. The prospective survey based on 40 children presented 1-2 forms of NB. The control group consisted of 36 patients with analogical symptoms for whom LB was excluded. Our long-term observation showed a low risk of developing long-term complications in children who received antibiotic therapy in accordance with the recommendations. The concentration of anti-VlsE IgG demonstrates a statistical significance for differences between the control and the study groups for each measurement period. Higher values of anti-VlsE IgG were observed in the study group, and the concentration decreased from the first measurement period to the next. The article emphasizes the importance of the long-term follow-up of children with neuroborreliosis.\n\nID: 36958992\nTitle: Systematic comparisons between Lyme disease and post-treatment Lyme disease syndrome in the U.S. with administrative claims data.\nAbstract: Post-treatment Lyme disease syndrome (PTLDS) is used to describe Lyme disease patients who have the infection cleared by antibiotic but then experienced persisting symptoms of pain, fatigue, or cognitive impairment. Currently, little is known about the cause or epidemiology of PTLDS. We conducted a data-driven study with a large nationwide administrative dataset, which consists of more than 98 billion billing and 1.4 billion prescription records between 2008 and 2016, to identify unique aspects of PTLDS that could have diagnostic and etiologic values. We defined PTLDS based on its symptomatology and compared the demographic, longitudinal changes of comorbidity, and antibiotic prescriptions between patients who have Lyme with absence of prolonged symptoms (APS) and PTLDS. The age and temporal distributions were similar between Lyme APS and PTLDS. The PTLDS-to-Lyme APS case ratio was 3.42%. The co-occurrence of 3 out of 19 chronic conditions were significantly higher in PTLDS versus Lyme APS-odds ratio and 95% CI for anemia, hyperlipidemia, and osteoarthrosis were 1.46 (1.11-1.92), 1.39 (1.15-1.68), and 1.62 (1.23-2.12) respectively. We did not find significant differences between PTLDS and Lyme APS for the number of types of antibiotics prescribed (incidence rate ratio\u00a0=\u00a01.009, p\u00a0=\u00a00.90) and for the prescription of each of the five antibiotics (FDR adjusted p values 0.72-0.95). PTLDS cases have more codes corresponding to anemia, hyperlipidemia, and osteoarthrosis compared to Lyme APS. Our finding of hyperlipidemia is consistent with a dysregulation of fat metabolism reported by other researchers, and further investigation should be conducted to understand the potential biological relationship between the two.

In some patients, however, problems persist for a long time despite appropriate therapy. The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome.\n\nID: 42359130\nTitle: Patient roadmap and economic burden of chronic tick-borne illness and post-treatment Lyme disease syndrome in Ireland, and public health issues arising.\nAbstract: Lyme borreliosis (LB), commonly referred to as Lyme disease (LD), is a prominent global health issue, exhibiting a seroprevalence rate of 14.5%. Heightened incidence levels of LD have been recorded in parts of Europe, Poland, Eastern Europe, and the Baltic States. The research aimed to inform the cost of LD and post-treatment Lyme disease syndrome (PTLDS) in Ireland through results from a patient questionnaire, disease modelling, the construction of a patient roadmap, and attempts to arrive at prevalence calculation estimates based on local data. Patient data encompassed sociodemographic particulars, disease attributes, healthcare resource utilization, and the influence on their employment status. Of 301 patients, 210 were diagnosed with LD and/or a tick-borne infection (TBI), the cohort's average age was 40.07 (SD 13.5) (N\u202f=\u202f210; Female:Male 60:40). The mean duration of symptoms in PTLDS patients was 7.15\u202fyears. The average number of visits to other healthcare professionals was 16.8 per patient. Regarding current employment status, the data indicates that 50.2% of respondents were currently working, 10.1% were unemployed, 8.7% were retired, 5.3% had caring responsibilities, 11.1% were on sick leave, and 14.5% fell into the \"Other\" category. Additionally, when asked if symptoms had affected their employment status, 69% of respondents said yes, 26% said no, and 5% did not respond. Modeling efforts show that the roadmap to care for PTLDS is challenging, leading to wandering from specialty to specialty and high healthcare utilization. Utilizing a novel method of indirect reverse estimation, our lifetime risk or cumulative incidence of PTLDS estimation is at 0.003%. Lack of data collection from Irish health authorities is leaving the issue of the cost of LD and PTLDS hard to address, despite efforts from our single-site study.\n\nID: 40692686\nTitle: Genomic characterization and antibiotic susceptibility of biofilm-forming Borrelia afzelii and Borrelia garinii from patients with erythema migrans.\nAbstract: Borrelia afzelii and Borrelia garinii are the leading causes of Lyme borreliosis (LB) in Europe. Persistent LB forms may involve biofilms, potentially contributing to antibiotic tolerance. Whole genome sequencing (WGS) was conducted on 7 B. afzelii and 5 B. garinii isolates from erythema migrans skin biopsies. Biofilms were analyzed for extracellular DNA (eDNA) content and biomass. A phenol red metabolic assay assessed the minimum inhibitory concentration (MIC) and minimum biofilm inhibitory concentration (MBIC) of amoxicillin, azithromycin, ceftriaxone, and doxycycline. Phylogenetic analysis revealed B. afzelii and B. garinii formed distinct clades, while B. burgdorferi B31 clustered separately. Core genome analysis showed 38.9% of genes were shared between B. afzelii and B. garinii, decreasing to 26.1% with B. burgdorferi. The cloud genome expanded from 34.4% to 53.4% with the addition of B. burgdorferi. No antimicrobial resistance genes were detected. Surface adhesion gene profiles exhibited significant variation across species, suggesting potential functional differences in host adaptation. B. afzelii and B. garinii species exhibited biofilms, with biomass correlating significantly with eDNA production. MIC values were 0.25 \u03bcg/mL (amoxicillin, ceftriaxone), 0.125 \u03bcg/mL (azithromycin), and 0.5 \u03bcg/mL (doxycycline), with no significant interspecies differences. However, MBIC values were considerably higher: 2 \u03bcg/mL (amoxicillin, azithromycin), 16 \u03bcg/mL (ceftriaxone), and 32 \u03bcg/mL (doxycycline). Biofilms in B. afzelii and B. garinii significantly reduce antibiotic efficacy, particularly ceftriaxone and doxycycline. These in vitro findings highlight the need for targeted therapeutic strategies and suggest biofilms may impact treatment outcomes in LB.\n\nID: 40265182\nTitle: A pilot study of disulfiram for individuals with persistent symptoms despite prior antibiotic treatment for Lyme disease.\nAbstract: In vitro studies report that disulfiram is effective in killing Borrelia burgdorferi. Case series suggest disulfiram may help to reduce the symptoms of patients with persistent symptoms despite prior antibiotic treatment for Lyme disease. This pilot study assessed safety, tolerability, and signs of clinical response. Participants with a history of previously treated Lyme disease and persistent fatigue were randomly assigned in a double-blinded fashion to either Group A (disulfiram for 4 weeks and placebo for 4 weeks) or Group B (disulfiram for 8 weeks). Primary outcome endpoint was at 10 weeks with a follow-up at 14 weeks. The primary aim was to assess safety and tolerability. A clinical aim assessed signs of clinical improvement using well-validated measures, focusing on improvement in fatigue and quality of life. Target enrollment was 24 participants. 940 individuals were screened, 11 were enrolled and nine participated in the trial. Dosing started low and increased based on response and tolerance to a maximum of 500 mg daily. Safety. Two participants discontinued medication due to clinical worsening, one of whom was briefly hospitalized. Three additional participants were withdrawn from treatment due to lab test abnormalities. Tolerability. Only three of nine participants completed the full course of treatment (two in Group A and one in Group B). Lower doses were better tolerated than the highest dose. Clinical response. Of nine participants, clinically meaningful improvement was noted in fatigue for six and in quality of life for four. Among the six fatigue responders, improvement was also noted on a multiple domain symptom index (six of six), overall symptom burden (five of six), and functional impairment (four of six). The study was terminated early due to end of project funding, higher than expected adverse events, and recognition that sufficient information was gathered to inform future studies. This study reveals the risks associated with disulfiram, especially at higher doses, while suggesting potential clinical benefits among some participants. Efficacy could not be assessed given the small sample size and the lack of a placebo-control group. https://clinicaltrials.gov/study/NCT03891667?cond=Lyme%20Disease&intr=disulfiram&rank=1, NCT03891667.\n\nID: 39581806\nTitle: Neuroborreliosis at the region of Asturias, Spain (2009-2022): Analysis of 38 cases.\nAbstract: Diagnosis of neurological involvement in Lyme disease is based on two-step serological testing and cerebrospinal fluid pleocytosis. In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients. The most frequent neurological syndromes were radiculoneuritis (36.84%), bilateral facial palsy (13.56%), radiculoneuritis and bilateral facial palsy (10.52%) and multiple cranial mononeuropathy (10.52%), among others. 78.9% achieved a complete recovery, and 15.79% developed post-treatment Lyme disease syndrome. Despite the high incidence of Lyme disease in Asturias, the cases based on hospital admission that can be classified as active disease are lower than those published based on hospital coding. The main source of diagnostic error is positive serological results, without other clinical context, especially in patients studied for cognitive impairment or encephalopathy.\n\nID: 37672279\nTitle: As Lyme Disease Expands Its Reach, New Research Offers Hope.\nAbstract: This Medical News article discusses Lyme disease epidemiology, post-treatment Lyme disease syndrome, and innovative research to prevent the tickborne infection.\n\nID: 37351009\nTitle: Does Biological Sex Matter in Lyme Disease? The Need for Sex-Disaggregated Data in Persistent Illness.\nAbstract: Biological sex should be included as an important variable in clinical research studies to identify outcome differences between men and women. Very few Lyme disease studies were designed to consider sex-based differences or gender bias as an important component of the research design. To assess sex-based differences in Lyme disease patients who were clinically diagnosed and reported remaining ill for six or more months after receiving antibiotic treatment, we analyzed self-reported clinical data from 2170 patients in the MyLymeData patient registry. We also reviewed previous Lyme disease studies for distribution of patients by biological sex according to stage of illness, data source, and definition of disease used as enrollment criteria. In MyLymeData, women reported more tick-borne coinfections, worse symptoms, longer diagnostic delays, more misdiagnoses, and worse functional impairment than men. No differences were reported in antibiotic treatment response or side effects. In our review, of clinical research trials and data sources, we identified a smaller percentage of women in studies of acute Lyme disease and a larger percentage of women in studies of persistent illness. Samples and data sources that were more reflective of patients seen in clinical practice had a higher percentage of women than randomized controlled trials and post-treatment Lyme disease studies. Our results indicate that biological sex should be integrated into Lyme disease research as a distinct variable. Future Lyme disease studies should include sex-based disaggregated data to illuminate differences that may exist between men and women with persistent illness.\n\nID: 36443755\nTitle: Lyme borreliosis in Belgium: a cost-of-illness analysis.\nAbstract: Lyme borreliosis (LB) is the most common tick-borne disease in Europe and North America, yet its economic burden remains largely unknown. This study aimed to estimate the economic cost associated with the different clinical manifestations of LB in Belgium. An incidence approach and societal perspective were used to estimate the total cost-of-illness for LB in Belgium. Costs were calculated for patients with erythema migrans (EM) or disseminated/late LB, including patients who developed post-treatment Lyme disease syndrome (PTLDS). Direct medical, direct non-medical (transportation & paid help) and indirect non-medical costs (productivity losses) were included in the analysis. Ambulatory cost data were collected through a prospective cohort study from June 2016 to March 2020, in which patients with LB were followed up 6 to 12\u00a0months after diagnosis. Hospitalization costs were retrieved from the Minimal Clinical Data registry, a mandatory registry for all Belgian hospitals, linked to the Minimal Financial Data registry. Costs were expressed in 2019 euros. The total annual cost associated with clinical manifestations of LB in Belgium was estimated at \u20ac5.59 million (95% UI 3.82-7.98). Of these, \u20ac3.44 million (95% UI 2.05-5.48) or 62% was related to disseminated/late LB diagnoses and \u20ac2.15 million (95% UI 1.30-3.26) to EM. In general, direct medical costs and productivity losses accounted for 49.8% and 46.4% of the total costs, respectively, while direct non-medical costs accounted for only 3.8%. The estimated mean costs were \u20ac193 per EM patient and \u20ac5,148 per disseminated/late LB patient. While patients with PTLDS seemed to have somewhat higher costs compared to patients without PTLDS, the number of patients was too small to have representative estimates. We estimate the total annual direct medical costs, direct non-medical and indirect non-medical costs associated with LB to exceed \u20ac5.5 million per year, almost evenly distributed between EM (40%) and disseminated/late LB (60%). EM costs 26 times less per patient but occurs also 16 times more frequently than disseminated/late LB. The cost burden remains limited by comparison to other infectious diseases due to the relative lower incidence.\n\nID: 36171561\nTitle: Non-specific symptoms and post-treatment Lyme disease syndrome in patients with Lyme borreliosis: a prospective cohort study in Belgium (2016-2020).\nAbstract: Patients with Lyme borreliosis (LB) may report persisting non-specific symptoms such as fatigue, widespread musculoskeletal pain or cognitive difficulties. When present for more than 6\u00a0months and causing a reduction in daily activities, this is often referred to as post-treatment Lyme disease syndrome (PTLDS). This study aimed to compare the occurrence of symptoms between LB patients and controls, to estimate the proportion of LB patients developing PTLDS and to identify risk factors. A prospective cohort study was set up including three subpopulations: patients with an erythema migrans (EM) (i) or disseminated/late LB (ii) and a non-LB control group (iii). At 6- and 12-months follow-up, the occurrence of several symptoms, including six symptoms used to define PTLDS, i.e. muscle pain, joint pain, fatigue, memory problems, difficulties concentrating and problems finding words, and impact on daily activities, was compared between LB patients and controls. Finally, the proportion of LB patients developing PTLDS as defined by the Infectious Disease Society of America was estimated, including a time frame for symptoms to be present. Although the risk of presenting PTLDS-related symptoms was significantly higher in EM patients (n\u2009=\u2009120) compared to controls (n\u2009=\u2009128) at 6\u00a0months follow-up, the risk of presenting at least one of these symptoms combined with impact on daily activities was not significantly higher in EM patients, at either 6- or 12-months follow-up. A significant association was found between disseminated/late LB (n\u2009=\u200915) and the occurrence of any PTLDS-symptom with an impact on daily activities at both time points. The proportion of patients with PTLDS was estimated at 5.9% (95% CI 2.7-12.9) in EM patients and 20.9% (95% CI 6.8-64.4) in patients with disseminated/late LB (RR\u2009=\u20093.53, 95% CI 0.98-12.68, p\u2009=\u20090.053). No significant risk factors were identified, which may be explained by small sample sizes. In our study, PTLDS was present in both LB cohorts, yet with a higher percentage in disseminated/late LB patients. Additional research is needed into risk factors for and causes of this syndrome. In addition, development and validation of standardized methods to assess the PTLDS case definition, easily applicable in practice, is of great importance.\n\nID: 35884166\nTitle: Efficacy of Short-Term High Dose Pulsed Dapsone Combination Therapy in the Treatment of Chronic Lyme Disease/Post-Treatment Lyme Disease Syndrome (PTLDS) and Associated Co-Infections: A Report of Three Cases and Literature Review.\nAbstract: Lyme disease and associated co-infections are increasing worldwide and approximately 20% of individuals develop chronic Lyme disease (CLD)/Post-Treatment Lyme Disease Syndrome (PTLDS) despite early antibiotics. A seven- to eight-week protocol of double dose dapsone combination therapy (DDDCT) for CLD/PTLDS results in symptom remission in approximately 50% of patients for one year or longer, with published culture studies indicating higher doses of dapsone demonstrate efficacy against resistant biofilm forms of Borrelia burgdorferi. The purpose of this study was, therefore, to evaluate higher doses of dapsone in the treatment of resistant CLD/PTLDS and associated co-infections. A total of 25 patients with a history of Lyme and associated co-infections, most of whom had ongoing symptoms despite several courses of DDDCT, took one or more courses of high dose pulsed dapsone combination therapy (200 mg dapsone \u00d7 3-4 days and/or 200 mg BID \u00d7 4 days), depending on persistent symptoms. The majority of patients noticed sustained improvement in eight major Lyme symptoms, including fatigue, pain, headaches, neuropathy, insomnia, cognition, and sweating, where dapsone dosage, not just the treatment length, positively affected outcomes. High dose pulsed dapsone combination therapy may represent a novel therapeutic approach for the treatment of resistant CLD/PTLDS, and should be confirmed in randomized, controlled clinical trials.\n\nID: 35764331\nTitle: Management and clinical outcomes of Lyme disease in acute care facilities in 2 endemic regions of Quebec, Canada: a multicentre retrospective cohort study.\nAbstract: Despite increases in cases of Lyme disease, little is known about the management and clinical course of the disease in Canada. We aimed to describe the management and clinical course of Lyme disease in patients treated in acute care facilities in Quebec and to assess adherence to the 2006 Infectious Diseases Society of America (IDSA) guideline. This retrospective multicentre cohort study included pediatric and adult patients with serologically confirmed Lyme disease treated in acute care facilities (12 community hospitals and 2 tertiary care centres) of 2 endemic regions of Quebec (Estrie and Mont\u00e9r\u00e9gie), from 2004 to 2017. We considered drug choice, prescribed dose and treatment duration in assessing adherence of prescriptions to the 2006 IDSA guideline. The main outcome was complete resolution of symptoms at 3 months after the initiation of treatment. We included 272 patients from 14 institutions (age range 3-87 yr). Early disseminated Lyme disease (140 patients [51%]) was predominant. Adherence to the IDSA guideline was observed in 235 (90%) of the 261 cases with complete information, and adherence was stable over time (2004-2013: 57/64 [89%]; 2014-2015: 64/71 [90%]; 2016-2017: 114/126 [90%]; p = 0.8). Non-adherence to the guideline (n = 26) was predominantly due to longer-than-recommended treatment duration (16/26 [62%]). Resolution of objective signs at 3 months after treatment initiation occurred in 265 (99%) of 267 patients, whereas post-treatment Lyme disease syndrome was observed in 27 patients (10%) with increasing incidence over time (2004-2013: 3/65 [5%]; 2014-2015: 4/73 [5%]; 2016-2017: 20/129 [16%]; p = 0.02). We observed clinical resolution of Lyme disease in 99% of the patients, and most treatments (90%) complied with the 2006 IDSA guideline. The incidence of post-treatment Lyme disease syndrome increased over the study period, warranting further prospective studies.\n\nID: 35336182\nTitle: Multidisciplinary Management of Suspected Lyme Borreliosis: Clinical Features of 569 Patients, and Factors Associated with Recovery at 3 and 12 Months, a Prospective Cohort Study.\nAbstract: Introduction. Because patients with a suspicion of Lyme borreliosis (LB) may have experienced difficult care paths, the Tick-Borne Diseases Reference Center (TBD-RC) was started in 2017. The aim of our study was to compare the clinical features of patients according to their final diagnoses, and to determine the factors associated with recovery in the context of multidisciplinary management for suspected LB. Methods. We included all adult patients who were seen at the TBD-RC (2017-2020). Four groups were defined: (i) confirmed LB, (ii) possible LB, (iii) Post-Treatment Lyme Disease Syndrome (PTLDS) or sequelae, and (iv) other diagnoses. Their clinical evolution at 3, 6, and 9-12 months after care was compared. Factors associated with recovery at 3 and at 9-12 months were identified using logistic regression models. Results. Among the 569 patients who consulted, 72 (12.6%) had confirmed LB, 43 (7.6%) possible LB, 58 (10.2%) PTLDS/sequelae, and 396 (69.2%) another diagnosis. A favorable evolution was observed in 389/569 (68.4%) at three months and in 459/569 (80.7%) at 12 months, independent of the final diagnosis. A longer delay between the first symptoms and the first consultation at the TBD-RC (p = 0.001), the multiplicity of the diagnoses (p = 0.004), and the inappropriate prescription of long-term antibiotic therapy (p = 0.023) were negatively associated with recovery, reflecting serial misdiagnoses. Conclusions. A multidisciplinary team dedicated to suspicion of LB may achieve a more precise diagnosis and better patient-centered medical support in the adapted clinical sector with a shorter delay, enabling clinical improvement and avoiding inappropriate antimicrobial prescription.\n\nID: 40511782\nTitle: Cycles of (Dis)engagement: A Qualitative Meta-Synthesis of the (Health)Care-Seeking Experiences of Patients with Chronic Symptoms Following Lyme Disease.\nAbstract: (Chronic) Lyme disease/post-treatment Lyme disease syndrome ([C]LD/PTLDS) is a post-infection illness that remains contested, resulting in a divergent epistemological landscape (i.e., biomedicine versus alternative medicine). Consequently, (C)LD/PTLDS patients exhaust their (health)care options in their search for symptom relief, falling into cycles of starting and stopping (health)care-seeking. This meta-synthesis reviewed 13 qualitative interview studies representing the (health)care-seeking experiences of 216 (C)LD/PTLDS patients across five countries (i.e., United States, Canada, Netherlands, Australia, France) to examine how communication catalyzes patients' (health)care-seeking behaviors. This study proposes a model of (health)care (dis)engagement, identifying communication as a motor moving patients through (health)care-seeking both within and outside of biomedical models of care. This model extends our understanding of communicative (dis)enfranchisement processes and understandings of why patients disengage and reengage in healthcare-seeking behaviors. Theoretical and practical implications and future directions are discussed.\n\nID: 35885840\nTitle: Kundalini Yoga for Post-Treatment Lyme Disease: A Preliminary Randomized Study.\nAbstract: This study examined the adherence to and the potential benefit of Kundalini yoga (KY) for post-treatment Lyme disease syndrome (PTLDS). Participants were randomly assigned to 8 weeks of a KY small-group intervention or a waitlist control (WLC). Adherence was measured as attendance at KY group sessions. Primary outcomes assessed pain, pain interference, fatigue, and global health. Secondary outcomes assessed multisystem symptom burden, mood, sleep, physical and social functioning, cognition, and mindfulness. Linear mixed models were used to test changes in outcomes over time as a function of group assignment; intercepts for participants were modeled as random effects. Although the target sample size was 40 participants, the study concluded with 29 participants due to recruitment challenges. No KY participants dropped out of the study, and participants attended 75% of group sessions on average, but WLC retention was poor (57%). Regarding primary outcomes, there was no significant interaction between group and time. Regarding secondary outcomes, there was a significant interaction between group and time for multisystem symptom burden (p < 0.05) and cognition (p < 0.01); KY participants reported improved multisystem symptom burden and cognition over the course of the study compared to WLC participants. To enhance recruitment and retention, future trials may consider expanding geographic access and including supportive procedures for WLC participants. This preliminary study supports the need for a larger study to determine if KY reduces multisystem symptom burden and enhances cognition among people with PTLDS.\n\nID: 35027599\nTitle: Neuropathogenicity of non-viable Borrelia burgdorferi ex vivo.\nAbstract: Even after appropriate treatment, a proportion of Lyme disease patients suffer from a constellation of symptoms, collectively called Post-Treatment Lyme Disease Syndrome (PTLDS). Brain PET scan of patients with PTLDS have demonstrated likely glial activation indicating persistent neuroinflammatory processes. It is possible that unresolved bacterial remnants can continue to cause neuroinflammation. In previous studies, we have shown that non-viable Borrelia burgdorferi can induce neuroinflammation and apoptosis in an oligodendrocyte cell line. In this follow-up study, we analyze the effect of sonicated remnants of B. burgdorferi on primary rhesus frontal cortex (FC) and dorsal root ganglion (DRG) explants. Five FC and three DRG tissue fragments from rhesus macaques were exposed to sonicated B. burgdorferi and analyzed for 26 inflammatory mediators. Live bacteria and medium alone served as positive and negative control, respectively. Tissues were also analyzed for cell types mediating inflammation and overall apoptotic changes. Non-viable B. burgdorferi induced significant levels of several inflammatory mediators in both FC and DRG, similar to live bacteria. However, the levels induced by non-viable B. burgdorferi was often (several fold) higher than those induced by live ones, especially for IL-6, CXCL8 and CCL2. This effect was also more profound in the FC than in the DRG. Although the levels often differed, both live and dead fragments induced the same mediators, with significant overlap between FC and DRG. In the FC, immunohistochemical staining for several inflammatory mediators showed the presence of multiple mediators in astrocytes, followed by microglia and oligodendrocytes, in response to bacterial remnants. Staining was also seen in endothelial cells. In the DRG, chemokine/cytokine staining was predominantly seen in S100 positive (glial) cells. B. burgdorferi remnants also induced significant levels of apoptosis in both the FC and DRG. Apoptosis was confined to S100\u2009+\u2009cells in the DRG while distinct neuronal apoptosis was also detected in most FC tissues in response to sonicated bacteria. Non-viable B. burgdorferi can continue to be neuropathogenic to both CNS and PNS tissues with effects likely more profound in the former. Persistence of remnant-induced neuroinflammatory processes can lead to long term health consequences.\n\nID: 33126203\nTitle: Classification of patients referred under suspicion of tick-borne diseases, Copenhagen, Denmark.\nAbstract: To provide better care for patients suspected of having a tick-transmitted infection, the Clinic for Tick-borne Diseases at Rigshospitalet, Copenhagen, Denmark was established. The aim of this prospective cohort study was to evaluate diagnostic outcome and to characterize demographics and clinical presentations of patients referred between the 1st of September 2017 to 31st of August 2019. A diagnosis of Lyme borreliosis was based on medical history, symptoms, serology and cerebrospinal fluid analysis. The patients were classified as definite Lyme borreliosis, possible Lyme borreliosis or post-treatment Lyme disease syndrome. Antibiotic treatment of Lyme borreliosis manifestations was initiated in accordance with the national guidelines. Patients not fulfilling the criteria of Lyme borreliosis were further investigated and discussed with an interdisciplinary team consisting of specialists from relevant specialties, according to individual clinical presentation and symptoms. Clinical information and demographics were registered and managed in a database. A total of 215 patients were included in the study period. Median age was 51 years (range 17-83 years), and 56 % were female. Definite Lyme borreliosis was diagnosed in 45 patients, of which 20 patients had erythema migrans, 14 patients had definite Lyme neuroborreliosis, six had acrodermatitis chronica atrophicans, four had multiple erythema migrans and one had Lyme carditis. Furthermore, 12 patients were classified as possible Lyme borreliosis and 12 patients as post-treatment Lyme disease syndrome. A total of 146 patients (68 %) did not fulfil the diagnostic criteria of Lyme borreliosis. Half of these patients (73 patients, 34 %) were diagnosed with an alternative diagnosis including inflammatory diseases, cancer diseases and two patients with a tick-associated disease other than Lyme borreliosis. A total of 73 patients (34 %) were discharged without sign of somatic disease. Lyme borreliosis patients had a shorter duration of symptoms prior to the first hospital encounter compared to patients discharged without a specific diagnosis (p<0.001). When comparing symptoms at presentation, patients discharged without a specific diagnosis suffered more often from general fatigue and cognitive dysfunction. In conclusion, 66 % of all referred patients were given a specific diagnosis after ended outpatient course. A total of 32 % was diagnosed with either definite Lyme borreliosis, possible Lyme borreliosis or post-treatment Lyme disease syndrome; 34 % was diagnosed with a non-tick-associated diagnosis. Our findings underscore the complexity in diagnosing Lyme borreliosis and the importance of ruling out other diseases through careful examination.\n\nID: 32457042\nTitle: Lyme borreliosis: diagnosis and management.\nAbstract: Lyme borreliosis is the most common vectorborne disease in the northern hemisphere. It usually begins with erythema migrans; early disseminated infection particularly causes multiple erythema migrans or neurologic disease, and late manifestations predominantly include arthritis in North America, and acrodermatitis chronica atrophicans (ACA) in Europe. Diagnosis of Lyme borreliosis is based on characteristic clinical signs and symptoms, complemented by serological confirmation of infection once an antibody response has been mounted. Manifestations usually respond to appropriate antibiotic regimens, but the disease can be followed by sequelae, such as immune arthritis or residual damage to affected tissues. A subset of individuals reports persistent symptoms, including fatigue, pain, arthralgia, and neurocognitive symptoms, which in some people are severe enough to fulfil the criteria for post-treatment Lyme disease syndrome. The reported prevalence of such persistent symptoms following antimicrobial treatment varies considerably, and its pathophysiology is unclear. Persistent active infection in humans has not been identified as a cause of this syndrome, and randomized treatment trials have invariably failed to show any benefit of prolonged antibiotic treatment. For prevention of Lyme borreliosis, post-exposure prophylaxis may be indicated in specific cases, and novel vaccine strategies are under development.\n\nID: 30747990\nTitle: [Guideline for the diagnosis and treatment of Lyme borreliosis].\nAbstract: The national guideline aims to highlight the latest knowledge about clinical manifestations of the infection, to summarize the diagnostic algorithm and to recommend the appropriate antibiotic therapy with respect to evidence-based medicine. The recommendations are consistent with most European guidelines as well as those published by the IDSA. The guideline provides the most recent information on the epidemiology, etiology and pathogenesis of Lyme borreliosis, dermatological, neurological and musculoskeletal involvement, the appropriate diagnostic procedure and prevention. Some information is also provided about post-treatment Lyme disease syndrome. Recommended oral and intravenous antimicrobials are listed in a table showing the doses and duration of therapy. The guideline also mentions diagnostic methods to be avoided or whose results should be interpreted with caution. Although the guideline cannot account for all individual variations among patients, it may provide instructions to physicians in typical and frequent clinical situations.\n\nID: 30567544\nTitle: Imaging glial activation in patients with post-treatment Lyme disease symptoms: a pilot study using [11C]DPA-713 PET.\nAbstract: The pathophysiology of post-treatment Lyme disease syndrome (PTLDS) may be linked to overactive immunity including aberrant activity of the brain's resident immune cells, microglia. Here we used [11C]DPA-713 and positron emission tomography to quantify the 18\u2009kDa translocator protein, a marker of activated microglia or reactive astrocytes, in the brains of patients with post-treatment Lyme disease symptoms of any duration compared to healthy controls. Genotyping for the TSPO rs6971 polymorphism was completed, and individuals with the rare, low affinity binding genotype were excluded. Data from eight brain regions demonstrated higher [11C]DPA-713 binding in 12 patients relative to 19 controls. [11C]DPA-713 PET is a promising tool to study cerebral glial activation in PTLDS and its link to cognitive symptoms.\n\nID: 27922168\nTitle: Update of the Swiss guidelines on post-treatment Lyme disease syndrome.\nAbstract: Lyme borreliosis is caused by Borrelia burgdorferi sensu lato infection, which responds well to antibiotic therapy in the overwhelming majority of cases. However, despite adequate antibiotic treatment some patients report persisting symptoms which are commonly summarised as post-treatment Lyme disease syndrome (PTLDS). In 2005, the Swiss Society of Infectious Diseases published a case definition for PTLDS. We aimed to review the scientific literature with a special emphasis on the last 10 years, questioning whether the definitions from 2005 are still valid in the light of current knowledge. Furthermore, we describe the clinical history of infection with Borrelia burgdorferi sensu lato, the estimated prevalence of PTLDS, the possible pathogenesis of PTLDS, and treatment options with an emphasis on clinical studies. In summary, we were unable to find a scientific reason for modification of the PTLDS definitions published in 2005. Thus, the diagnostic criteria remain unchanged, namely documented clinical and laboratory evidence of previous infection with B. burgdorferi, a completed course of appropriate antibiotic therapy, symptoms including fatigue, arthralgia, myalgia, cognitive dysfunction or radicular pain persisting for >6 months, a plausible timely association between documented B. burgdorferi infection and onset of symptoms (i.e., persistent or recurrent symptoms that began within 6 months of completion of a recommended antibiotic therapy for early or late Lyme borreliosis), and exclusion of other somatic or psychiatric causes of symptoms. The main therapeutic options remain cognitive behavioural therapy and low-impact aerobic exercise programmes. Growing and unequivocal evidence confirms that prolonged or repeated antibiotic therapy for PTLDS is not beneficial, but potentially harmful and therefore contraindicated. The Guidelines of the Swiss Society of Infectious Diseases offer an evidence based, diagnostic and therapeutic framework for physicians caring for patients suffering from presumptive PTLDS in Switzerland.\n\nID: 25650808\nTitle: Health care costs, utilization and patterns of care following Lyme disease.\nAbstract: Lyme disease is the most frequently reported vector borne infection in the United States. The Centers for Disease Control have estimated that approximately 10% to 20% of individuals may experience Post-Treatment Lyme Disease Syndrome - a set of symptoms including fatigue, musculoskeletal pain, and neurocognitive complaints that persist after initial antibiotic treatment of Lyme disease. Little is known about the impact of Lyme disease or post-treatment Lyme disease symptoms (PTLDS) on health care costs and utilization in the United States. 1) to examine the impact of Lyme disease on health care costs and utilization, 2) to understand the relationship between Lyme disease and the probability of developing PTLDS, 3) to understand how PTLDS may impact health care costs and utilization. This study utilizes retrospective data on medical claims and member enrollment for persons aged 0-64 years who were enrolled in commercial health insurance plans in the United States between 2006-2010. 52,795 individuals treated for Lyme disease were compared to 263,975 matched controls with no evidence of Lyme disease exposure. Lyme disease is associated with $2,968 higher total health care costs (95% CI: 2,807-3,128, p<.001) and 87% more outpatient visits (95% CI: 86%-89%, p<.001) over a 12-month period, and is associated with 4.77 times greater odds of having any PTLDS-related diagnosis, as compared to controls (95% CI: 4.67-4.87, p<.001). Among those with Lyme disease, having one or more PTLDS-related diagnosis is associated with $3,798 higher total health care costs (95% CI: 3,542-4,055, p<.001) and 66% more outpatient visits (95% CI: 64%-69%, p<.001) over a 12-month period, relative to those with no PTLDS-related diagnoses. Lyme disease is associated with increased costs above what would be expected for an easy to treat infection. The presence of PTLDS-related diagnoses after treatment is associated with significant health care costs and utilization.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The aim of this exploratory study was to evaluate the feasibility of protein biomarker profiling as a diagnostic platform for this category of patients and to compare these results with similarly obtained results from a group of patients with acute neuroborreliosis. Two groups of patient cohorts (Cohort 1 and 2) were analyzed for biomarkers in serum and cerebrospinal fluid (CSF); the results were used for group-level comparison. Cohort 1 comprised 158 adult patients selected from 224 previously diagnosed patients, who between October 2015 and December 2018, after referral, were enrolled and structurally investigated based on defined inclusion criteria. They displayed similar lingering symptoms, with a duration of at least 6 months, after presumed previous tick-borne infection (TBI) and are fully described in a previously published study originating from the Center for Vector-borne Infections (CVI), Uppsala University Hospital, Sweden. Cohort 2, comprised 30 patients diagnosed at Uppsala University Hospital between 2016 and 2019 with laboratory-confirmed acute neuroborreliosis. Their proteomic results, based on serum and CSF analyses, were compared with the 158 patients in Cohort 1. The expression and the concentration of potential biomarkers in each patient's serum and CSF samples were measured based on two multiplex protein panels enabling simultaneous analysis of 92 inflammatory and neurology biomarkers. The PTLDS patient subgroup showed no nominally significant proteins compared to the other CVI patients in Cohort 1. However, CVI patients with signs of inflammation, which were evenly distributed in Cohort 1, showed 16 significantly (p <0.05) different proteins in both CSF and serum, but no association was seen with laboratory-confirmed exposure to Borrelia spp or other TBIs. When comparing the two cohorts, different protein profiles were observed, with 125/148 significantly different proteins in CSF and 93/174 in serum, in patients with laboratory confirmed acute neuroborreliosis, of which 6 in CSF and 6 in serum were significant at the p <0.001 level. In this first comprehensive inflammatory and neurological biomarker profile study no differences in biomarker profiles were detected between patients with PTLDS and patients with similar persisting symptoms but who did not meet the PTLDS criteria, regardless of whether laboratory verified previous exposure to Borrelia or other TBI's were present. However, the expressed markers differed from those found in patients with confirmed acute neuroborreliosis, which does not support the view that PTLDS reflects an ongoing Borrelia infection. Further studies are needed to understand and assess the usefulness of biosignatures of patients with PTLDS before they can be applied in a clinical setting.\n  --- END ACTUAL ABSTRACT FOR 36327322 ---\n\n- ERROR: You cited ID: 35027599 for the quote: \"Non-viable Borrelia burgdorferi can induce neuroinflammation and apoptosis in an oligodendrocyte cell line.\"\n  FACT: Strict Misquote Detected!

Brain PET scan of patients with PTLDS have demonstrated likely glial activation indicating persistent neuroinflammatory processes. It is possible that unresolved bacterial remnants can continue to cause neuroinflammation. In previous studies, we have shown that non-viable Borrelia burgdorferi can induce neuroinflammation and apoptosis in an oligodendrocyte cell line. In this follow-up study, we analyze the effect of sonicated remnants of B. burgdorferi on primary rhesus frontal cortex (FC) and dorsal root ganglion (DRG) explants. Five FC and three DRG tissue fragments from rhesus macaques were exposed to sonicated B. burgdorferi and analyzed for 26 inflammatory mediators. Live bacteria and medium alone served as positive and negative control, respectively. Tissues were also analyzed for cell types mediating inflammation and overall apoptotic changes. Non-viable B. burgdorferi induced significant levels of several inflammatory mediators in both FC and DRG, similar to live bacteria. However, the levels induced by non-viable B. burgdorferi was often (several fold) higher than those induced by live ones, especially for IL-6, CXCL8 and CCL2. This effect was also more profound in the FC than in the DRG. Although the levels often differed, both live and dead fragments induced the same mediators, with significant overlap between FC and DRG. In the FC, immunohistochemical staining for several inflammatory mediators showed the presence of multiple mediators in astrocytes, followed by microglia and oligodendrocytes, in response to bacterial remnants. Staining was also seen in endothelial cells. In the DRG, chemokine/cytokine staining was predominantly seen in S100 positive (glial) cells. B. burgdorferi remnants also induced significant levels of apoptosis in both the FC and DRG. Apoptosis was confined to S100\u2009+\u2009cells in the DRG while distinct neuronal apoptosis was also detected in most FC tissues in response to sonicated bacteria. Non-viable B. burgdorferi can continue to be neuropathogenic to both CNS and PNS tissues with effects likely more profound in the former. Persistence of remnant-induced neuroinflammatory processes can lead to long term health consequences.\n  --- END ACTUAL ABSTRACT FOR 35027599 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects.\" (Source: 41314472)\n- \"Im Rahmen eines systematischen Reviews zur Therapie des sogenannten Post-Treatment Lyme Disease Syndrome (PTLDS) zeigte sich, dass die untersuchten Parameter Lebensqualit\u00e4t, Fatigue, Depression und Kognition nicht auf eine antibiotische Therapie ansprechen.\" (Source: 41195425)\n- \"We found no differences between the groups in either cognitive function, cortical thickness or brain volumes.\" (Source: 36380166)\n- \"This review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS.\" (Source: 37784031)\n- \"Eligible studies show no statistically significant difference between antibiotics and placebo regarding quality of life, cognition and depression.\" (Source: 38606630)\n- \"At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024.\" (Source: 39161484)\n- \"After 6 months, the number of patients experiencing symptoms was significantly lower in the Pycnogenol\u00ae group compared to the control group across all symptoms (P<0.05).\" (Source: 40371616)\n- \"These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety.\" (Source: 41972549)\n- \"There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use.\" (Source: 41421419)\n- \"Data from eight brain regions demonstrated higher [11C]DPA-713 binding in 12 patients relative to 19 controls.\" (Source: 30567544)\n- \"The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history.\" (Source: 36836887)\n- \"Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification.\" (Source: 42391726)\n- \"Loss of identity and phobias were also highly suggestive of a psychogenic mechanism underlying amnesia.\" (Source: 38965869)\n- \"The lack of correlation between subjective and objective instruments highlights the limitations of the commonly used questionnaires with some patients overestimating and some underestimating true autonomic deficit.\" (Source: 38291116)\n- \"The results suggest that symptoms often categorized as Chronic-Lyme-Disease (CLD) in the general debate, cannot be uniquely linked to Lyme disease.\" (Source: 33735220)\n- \"The main source of diagnostic error is positive serological results, without other clinical context, especially in patients studied for cognitive impairment or encephalopathy.\" (Source: 39581806)\n- \"This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings.\" (Source: 42148664)\n- \"Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS.\" (Source: 41796643)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Current medical consensus, based on existing clinical trials and guidelines, indicates that there is no validated \"cure\" for this syndrome. Antibiotic re-treatment has consistently failed to demonstrate clinical efficacy and carries significant risk. Treatment approaches are currently limited to symptom management, multidisciplinary rehabilitation, and emerging investigation into immunomodulatory, neuromodulatory, and lifestyle interventions.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a complex, multifactorial, and controversial clinical entity. Research confirms that standard antibiotic regimens for the initial Lyme infection are effective; however, a subset of patients subsequently develops persistent, debilitating symptoms. Rigorous clinical investigations have demonstrated that prolonged or repeated antibiotic therapy provides no benefit for PTLDS patients and is associated with adverse events. The pathophysiology is currently the subject of extensive study, with hypotheses ranging from persistent inflammation and immune dysregulation to neuroinflammation, though no singular, quantifiable biomarker has yet been established to confirm the diagnosis or guide a curative therapy. Consequently, management is currently focused on mitigating symptoms rather than achieving a definitive cure.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Long-term antibiotic therapy for PTLDS is not recommended due to consistent failures in randomized controlled trials and the potential for serious adverse effects.\n*   Recent PET imaging studies suggest that PTLDS patients may exhibit cerebral glial activation, indicating a potential persistent neuroinflammatory process.\n*   Approximately 20% of patients with disseminated or late Lyme disease may develop PTLDS.\n*   There is a recognized disconnect between patient-reported (subjective) dysautonomia and objective clinical autonomic testing.\n*   A significant percentage of patients referred to specialty clinics for suspected Lyme disease are ultimately diagnosed with alternative conditions, highlighting the risks of misdiagnosis.\n*   Immunologic factors, such as the presence of myositis autoantibodies, have been identified in a subset of PTLDS patients.\n*   Online yoga and other mindfulness-based interventions have shown preliminary success in improving pain and cognitive performance in PTLDS cohorts.\n*   The economic burden of PTLDS is significant, with patients experiencing high healthcare utilization rates and notable impacts on employment status.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences."

Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor. Im Rahmen eines systematischen Reviews zur Therapie des sogenannten Post-Treatment Lyme Disease Syndrome (PTLDS) zeigte sich, dass die untersuchten Parameter Lebensqualit\u00e4t, Fatigue, Depression und Kognition nicht auf eine antibiotische Therapie ansprechen. F\u00fcr die Wirksamkeit anderer Therapieverfahren fanden sich keine aussagekr\u00e4ftigen Studien."

When these symptoms are unexplained by other conditions and persist for \u2265\u20096 months, this condition is called post-treatment Lyme disease symptoms or syndrome (PTLDS). The pathogenesis of PTLDS is unknown and no specific diagnostic biomarkers have been identified. In this study, we used a high-density peptide array to examine antibody responses to >\u200960 primary antigens of B. burgdorferi from a cohort of patients diagnosed with PTLDS and recovered patients with similar Lyme disease manifestations. Using matched serum and cerebrospinal fluid (CSF), we mapped the primary reactive B. burgdorferi epitopes associated with PTLDS. We found that VlsE had a greater antibody response within the PTLDS cohort than recovered patients. The reactivity to OspC-specific epitopes revealed a predominance of antibodies to OspC type K and A in the PTLDS cohort. However, the major immunodominant epitopes were similar in PTLDS and recovered patients, and we were unable to identify specific diagnostic targets for PTLDS. We found a more robust reactivity in the serum over CSF and did not identify antigenic regions that were specifically associated with the infection of the central nervous system."

It is a zoonosis caused by several species of Borrelia burgdorferi sensu lato and transmitted by the bite of infected ticks of the Ixodes ricinus complex. Lyme borreliosis in North America and Europe differs in certain respects, likely reflecting the different Borrelia species that cause human disease in these locations. The earliest manifestation of Lyme borreliosis is the skin lesion erythema migrans, which develops at the tick\u00a0bite site, typically 7-14 days after the bite. Some untreated patients will then (within the first few weeks or months after onset of the infection) develop additional erythema migrans skin lesions or other clinical manifestations such as borrelial lymphocytoma, nervous system involvement or carditis. Several months or even years after infection onset, Lyme arthritis or acrodermatitis chronica atrophicans may develop. The diagnosis of typical erythema migrans is clinical, whereas for all other manifestations\u00a0the diagnosis is supported via serological testing. Treatment with an appropriate antibiotic will result in resolution of clinical symptoms in most patients; however, some patients experience prolonged subjective symptoms, which usually improve over time. Repeated courses of antimicrobials are not beneficial except in rare cases when there is objective evidence of treatment failure."

This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination."

Existing standardized and modified two-tier tests (STT/MTT) suffer from poor detection rates in the first weeks of infection, where the antibody response, the basis of diagnosis, is developing but is not robust enough for detection. During this early window, false negative results are common, which leads to delayed treatment and increases the likelihood of developing severe symptoms. The InBios Lyme Detect Multiplex ELISA is a microarray-based assay designed to capture a set of commonly used diagnostic antibodies specific to Borrelia burgdorferi from human serum. The multiplex array captures common diagnostic antibodies, including those to C6, VlsE, and OspC, and has in-line controls. Diagnostic index scores are calculated from the relative abundance of controls and antibodies using a proprietary machine learning algorithm. The assay was evaluated here for reproducibility, accuracy, and performance. It was found to be reproducible using a group of 30 samples run in triplicate. The assay performed well in a blinded panel, correctly identifying all standard two-tier test-positive samples and controls while also detecting 21 of 79 samples that were clinically diagnosed but undetectable by standard Lyme serologic tests. There was one false positive from 66 look-alike disease samples and 146 healthy controls. The InBios assay has the potential to improve diagnostic sensitivity within the early weeks of infection while matching the specificity of current diagnostic tests. During initial Lyme disease infection, existing diagnostic tests have poor sensitivity, resulting in a high number of false-negative tests. This is due to the lag between infection and a robust immune response capable of being detected by such tests. With a multiplexed array of nine unique antibody targets specific for Borrelia burgdorferi, interpreted by a proprietary machine learning algorithm, the InBios Lyme Detect Multiplex ELISA has the potential to increase diagnostic sensitivity within the first few weeks of infection, reducing the number of false-negative tests.

Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated \u223c10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection."

Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS.

This review summarizes current knowledge on the pathogen-host interactions and immune responses. Early infection can be influenced by tick saliva, which suppresses local host defense and promotes spirochete survival, and by pattern recognition receptors activating proinflammatory cascades. Bbsl employs a variety of immune evasion strategies, notably impairing antigen presentation-through disruption of MHC II and IFN-\u03b3 pathways-and continuously varying surface antigens to hinder long-lasting antibody formation. Autophagy plays a central role in modulating inflammation and T helper 17 adaptive immune responses, representing an underappreciated mechanism potentially influencing disease outcome. Adaptive immunity in LB is characterized by robust but often dysregulated humoral and cellular responses, with transient germinal centers and enduring IgM production contributing to incomplete pathogen clearance. Persistent immune defects include impaired long-term B cell memory, suppressed T cell activation, and ongoing immunosuppression after pathogen clearance. Similar patterns are observed in other postinfectious fatigue syndromes. Despite advances, gaps remain in understanding mechanisms of Bbsl persistence and the immunopathology underlying chronic disease, challenging diagnosis and therapy. Emerging molecular and cellular approaches offer new avenues to address immunity, diagnostics, and prevention. A multidisciplinary effort will be needed to improve long-term patient outcomes in the evolving epidemiology of LB."

Heightened incidence levels of LD have been recorded in parts of Europe, Poland, Eastern Europe, and the Baltic States. The research aimed to inform the cost of LD and post-treatment Lyme disease syndrome (PTLDS) in Ireland through results from a patient questionnaire, disease modelling, the construction of a patient roadmap, and attempts to arrive at prevalence calculation estimates based on local data. Patient data encompassed sociodemographic particulars, disease attributes, healthcare resource utilization, and the influence on their employment status. Of 301 patients, 210 were diagnosed with LD and/or a tick-borne infection (TBI), the cohort's average age was 40.07 (SD 13.5) (N\u202f=\u202f210; Female:Male 60:40). The mean duration of symptoms in PTLDS patients was 7.15\u202fyears. The average number of visits to other healthcare professionals was 16.8 per patient. Regarding current employment status, the data indicates that 50.2% of respondents were currently working, 10.1% were unemployed, 8.7% were retired, 5.3% had caring responsibilities, 11.1% were on sick leave, and 14.5% fell into the \"Other\" category. Additionally, when asked if symptoms had affected their employment status, 69% of respondents said yes, 26% said no, and 5% did not respond. Modeling efforts show that the roadmap to care for PTLDS is challenging, leading to wandering from specialty to specialty and high healthcare utilization. Utilizing a novel method of indirect reverse estimation, our lifetime risk or cumulative incidence of PTLDS estimation is at 0.003%. Lack of data collection from Irish health authorities is leaving the issue of the cost of LD and PTLDS hard to address, despite efforts from our single-site study."

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions."

Disulfiram (DIS), a drug for alcoholism, is under investigation as a potential adjunctive treatment, but its low bioavailability, rapid metabolism, and safety concerns urge the development of improved formulations for clinical translation. Methods: Screening dissolution and permeation studies were investigated for vehicle and excipient selection, following the pharmacopeia perspectives to develop and optimize the low-dose DIS rectal suppository intended for application in post-treatment Lyme disease syndrome (PTLDS). Further characterizations were carried out by differential scanning calorimetry, X-ray diffraction, and infrared spectroscopy. Results: Cyclodextrin (CD) encapsulation was investigated to improve the aqueous solubility of the hydrophobic drug. The dissolution of DIS from fatty base suppository was very slow; it was remarkably improved by the molecular encapsulation of the drug with CDs. The dissolution of DIS from a water-soluble base was more favorable, but incomplete. In the polyethylene glycol (PEG) based suppositories, the addition of CDs already in a physical mixture ensured the dissolution of the drug. The presented drug delivery system relates to a novel preparation for rectal administration comprising a low-dose disulfiram with improved solubility and permeability by the PEG and hydroxypropyl-\u03b2-cyclodextrin (HPBCD) synergistic matrix. Conclusions: The rectal dosage form containing the drug and CD in the physical mixture is advantageous, avoiding the hepatic first-pass effect, minimizing dose-limiting toxicity, simplifying production, and fasting the availability of the repositioned drug."

Persons aged 18 years or older with persistent symptoms lasting six months or more attributed to tick bites or tick-borne diseases, were recruited into a nationwide cross-sectional study. Demographic data were recorded. Medical records were collected (February 2020 - April 2022) and reviewed for tick bites, tick-borne infections, antibiotic treatment, and clinical findings. Outcome measures included somatic symptoms (PHQ-15), fatigue (Fatigue Severity Scale), physical health (RAND-36), and affective symptoms (HAD Scale). Laboratory assessments included polymerase chain reaction (PCR) analysis of blood samples for Borrelia burgdorferi (Bb) and other known tick-borne pathogens, along with IgG antibody detection. The highest prevalence of persistent symptoms attributed to tick bites or tick-borne diseases was found in southwestern Norway (0.152-0.155%); the lowest was in the north (0.033%), which also had significantly lower Bb-IgG seroprevalence (15.4% compared to the national average 37.5%). Symptom persistence was not associated with confirmed tick exposure or tick-borne infection. Somatic symptoms were associated with low physical activity and comorbidity. Fatigue and poor physical health were strongly associated with underemployment. Fatigue was also associated with depressive symptoms, low activity, sick leave, and comorbidities. Persistent symptoms were most prevalent in tick-endemic regions but were not associated with prior tick exposure or tick-borne infections.

Characterized by fatigue, generalized myalgias, and cognitive impairment, PTLD symptomatology closely resembles long COVID and other post-acute infection syndromes. While prior studies suggest immune dysregulation as a factor in PTLD pathogenesis, the mechanisms underlying its heterogeneous presentation and severity remain unclear. To associate symptom burden with discrete immune phenotypes, we applied factor analysis to self-reported symptom data from 272 PTLD patients to generate patient subgroups. We then immunophenotyped peripheral blood cells of these individuals and 28 healthy controls through 19-parameter flow cytometry and cytokine profiling to associate PTLD status and the newly defined subgroups with specific immune states. Our PTLD cohort had fewer circulating CXCR5+ CD4+ na\u00efve T cells relative to healthy controls (5.2% vs. 8.3%, Padj < 0.001). These cells were positively associated with musculoskeletal pain in PTLD participants, but not healthy controls. This and additional immunophenotypic alterations, including an increased prevalence of CXCR3+ CCR4- CCR6- CD8 T cells (43.1% vs. 25.7%, Padj < 0.01), permitted the creation of an elastic net classifier which identified PTLD with moderate efficacy (AUC 0.83). Measurement of cytokines did not reveal associations with PTLD and did not improve the performance of the model. While we could not identify immune features which distinguished all patient subgroups, we did observe a female-specific increase in central memory CD8 T cells restricted to one high-fatigue patient subgroup. Additionally, factor analysis revealed multiple associations between immune cell frequency and the severity of specific symptoms.

In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients.

Post-Acute Sequelae of SARS-CoV-2 Infection (also known as Post-Acute Sequelae of COVID-19 (PASC) or more commonly, Long COVID) occurs in the aftermath of COVID-19 and is poorly understood despite its widespread effects. Methods: We created a machine-learning model that distinguishes PASC from PASC-similar diseases. The model was trained to recognize PASC-dysregulated metabolites (p \u2264 0.05) using molecular descriptors. Results: Our multi-layer perceptron model accurately recognizes PASC-dysregulated metabolites in the independent testing set, with an AUC-ROC of 0.8991, and differentiates PASC from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, postural orthostatic tachycardia syndrome (POTS), and irritable bowel syndrome (IBS). However, it was unable to differentiate fibromyalgia (FM) from PASC. Conclusions: By creating and testing models pairwise on each of these diseases, we elucidated the unique strength of the similarity between FM and PASC relative to other PASC-similar diseases. Our approach is unique to PASC diagnosis, and our use of molecular descriptors enables our model to work with any metabolite where molecular descriptors can be identified, as these descriptors can be generated and compared for any metabolite. Our study presents a novel approach to PASC diagnosis that partially circumvents the lengthy process of exclusion, potentially facilitating faster interventions and improved patient outcomes."

This article explores the historical and contemporary issues in diagnosing such conditions, emphasizing the fragmentation of medical and psychiatric knowledge, biases in clinical guidelines, and the mismanagement of complex illnesses. Diagnostic errors often arise from insufficient integration between general medicine and psychiatry, compounded by the reliance on population-based guidelines that neglect individual patient needs. Misclassification of conditions like myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, and fibromyalgia as psychosomatic or psychogenic has led to stigmatization and delayed care. While these conditions are referenced as emblematic examples of misclassified and poorly understood disorders, the five clinical cases discussed in this article do not directly illustrate these diseases. Instead, they exemplify shared diagnostic and ethical dilemmas at the medicine-psychiatry interface, including uncertainty, fragmentation, and the risk of epistemic injustice. The article critically examines terms like medically unexplained symptoms and functional disorders, highlighting their limitations and potential for misuse. Case examples underscore the consequences of diagnostic inaccuracies and the urgent need for improved approaches. Ethical considerations are also explored, emphasizing respecting patient experiences, promoting individualized care, and acknowledging the inherent uncertainties in medical diagnosis. Advances in technologies such as brain imaging and molecular diagnostics offer hope for bridging the gap between psychiatry and medicine, enabling more accurate assessments and better patient outcomes. The article concludes by advocating comprehensive training at the medicine-psychiatry interface and a patient-centered approach that integrates clinical observation, research insights, and a nuanced understanding of mind-body dynamics."

However, diagnosis can be particularly challenging in resource-limited settings where advanced tests are not readily available. Misclassification may result in non-selective chemotherapy exposure and increased toxicity. Reporting such cases is important to highlight diagnostic challenges in resource-limited countries. A 51-year-old male presented with abdominal discomfort, weight loss, and fatigue. Examination revealed splenomegaly. Initial evaluation suggested lymphoplasmacytic lymphoma, and the patient received multi-agent chemotherapy (R-CHOP), which was complicated by severe cytopenias. Splenectomy was performed, yielding a spleen weighing 2216\u00a0g. Histopathology and immunophenotyping confirmed hairy cell leukemia. Molecular testing for BRAF V600E (the gold standard for diagnosis) was unavailable due to financial and infrastructural restrictions. Treatment was switched to single-agent cladribine, resulting in marked clinical improvement and a significant reduction in chemotherapy adverse effects. Follow-up imaging and blood work revealed that the patient was in complete remission. In our case, we emphasize the diagnostic challenges of HCL in low-resource environments and clarify how the empirical administration of R-CHOP chemotherapy led to unnecessary toxicity and suboptimal outcomes. Splenectomy played a crucial diagnostic role when bone marrow tests were directional but not conclusive. We provide an extensive review of differential diagnoses, immunophenotypic hallmarks, what lies beyond the BRAF V600E mutation, and therapeutic approaches. Early recognition of HCL is crucial to avoid delayed optimal therapy and to enhance patient outcomes. This case emphasizes the critical role of morphology and immunophenotyping in confirming HCL, especially in resource-limited countries."

Treatment is predominantly management-focused rather than curative.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nWhile antibiotic therapy is highly effective for initial *Borrelia burgdorferi* infection, a subset of patients (10-20%) develop persistent symptoms (PTLDS). Evidence-based medicine currently lacks a curative regimen for PTLDS, with major clinical guidelines advising against long-term antibiotic or immunomodulatory therapy due to lack of demonstrated efficacy and risk of adverse effects. Management emphasizes a multidisciplinary, symptom-focused approach.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe management of Post-Treatment Lyme Disease Syndrome (PTLDS) remains one of the most significant challenges in modern infectious disease medicine. While clinical guidelines confirm that antibiotics are essential for the primary treatment of Lyme borreliosis, they do not resolve the post-infectious manifestations observed in a significant minority of patients. As stated in the provided literature, \"Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects.\" The persistence of symptoms such as fatigue, cognitive impairment, and diffuse pain, often lasting beyond six months, suggests a complex pathology that is not simply a residual infection. Consequently, clinical strategies have shifted toward symptom management, including physical rehabilitation and psychological support.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Current diagnostic markers are non-existent; PTLDS is currently diagnosed clinically based on symptoms following treated infection.\n*   \"Chronic Lyme disease\" is often used in popular media, but professional bodies like the IDSA prefer the term PTLDS to describe this specific post-treatment sequela.\n*   Persistent symptoms are not consistently linked to current/ongoing spirochete presence, leading to hypotheses regarding autoimmune responses or tissue damage.\n*   Symptoms of PTLDS share high phenotypic similarity with other infection-associated chronic conditions (IACCI) such as Long COVID and ME/CFS.\n*   There is a significant psychological and economic burden, with patients often \"wandering from specialty to specialty\" in search of diagnosis and relief.\n*   Therapeutic trials, including those for TPE (therapeutic plasma exchange), have largely failed in unselected populations, suggesting the future of treatment lies in biomarker-guided patient stratification.\n*   Recent research has begun to investigate mind-body interventions, such as online yoga, which have shown feasibility and benefits for symptom burden management.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions.\n\nID: 42359130\nTitle: Patient roadmap and economic burden of chronic tick-borne illness and post-treatment Lyme disease syndrome in Ireland, and public health issues arising.\nAbstract: Lyme borreliosis (LB), commonly referred to as Lyme disease (LD), is a prominent global health issue, exhibiting a seroprevalence rate of 14.5%. Heightened incidence levels of LD have been recorded in parts of Europe, Poland, Eastern Europe, and the Baltic States. The research aimed to inform the cost of LD and post-treatment Lyme disease syndrome (PTLDS) in Ireland through results from a patient questionnaire, disease modelling, the construction of a patient roadmap, and attempts to arrive at prevalence calculation estimates based on local data. Patient data encompassed sociodemographic particulars, disease attributes, healthcare resource utilization, and the influence on their employment status. Of 301 patients, 210 were diagnosed with LD and/or a tick-borne infection (TBI), the cohort's average age was 40.07 (SD 13.5) (N\u202f=\u202f210; Female:Male 60:40). The mean duration of symptoms in PTLDS patients was 7.15\u202fyears. The average number of visits to other healthcare professionals was 16.8 per patient. Regarding current employment status, the data indicates that 50.2% of respondents were currently working, 10.1% were unemployed, 8.7% were retired, 5.3% had caring responsibilities, 11.1% were on sick leave, and 14.5% fell into the \"Other\" category. Additionally, when asked if symptoms had affected their employment status, 69% of respondents said yes, 26% said no, and 5% did not respond. Modeling efforts show that the roadmap to care for PTLDS is challenging, leading to wandering from specialty to specialty and high healthcare utilization. Utilizing a novel method of indirect reverse estimation, our lifetime risk or cumulative incidence of PTLDS estimation is at 0.003%. Lack of data collection from Irish health authorities is leaving the issue of the cost of LD and PTLDS hard to address, despite efforts from our single-site study.\n\nID: 42148664\nTitle: Designing studies for post-treatment Lyme disease and other infection-associated chronic illnesses.\nAbstract: Infection-associated chronic illnesses (IACIs) encompass a spectrum of poorly understood syndromes often marked by significant neurologic and multisystem symptoms following an infectious event. This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs.\n\nID: 42083310\nTitle: Borrelia burgdorferi sensu lato Employs Several Escape Mechanisms to Bypass the Human Defense System.\nAbstract: Lyme borreliosis (LB), caused by Borrelia burgdorferi sensu lato (Bbsl) through Ixodes tick bites, presents diverse clinical manifestations and may lead to persistent symptoms. This review summarizes current knowledge on the pathogen-host interactions and immune responses. Early infection can be influenced by tick saliva, which suppresses local host defense and promotes spirochete survival, and by pattern recognition receptors activating proinflammatory cascades. Bbsl employs a variety of immune evasion strategies, notably impairing antigen presentation-through disruption of MHC II and IFN-\u03b3 pathways-and continuously varying surface antigens to hinder long-lasting antibody formation. Autophagy plays a central role in modulating inflammation and T helper 17 adaptive immune responses, representing an underappreciated mechanism potentially influencing disease outcome. Adaptive immunity in LB is characterized by robust but often dysregulated humoral and cellular responses, with transient germinal centers and enduring IgM production contributing to incomplete pathogen clearance. Persistent immune defects include impaired long-term B cell memory, suppressed T cell activation, and ongoing immunosuppression after pathogen clearance. Similar patterns are observed in other postinfectious fatigue syndromes. Despite advances, gaps remain in understanding mechanisms of Bbsl persistence and the immunopathology underlying chronic disease, challenging diagnosis and therapy. Emerging molecular and cellular approaches offer new avenues to address immunity, diagnostics, and prevention. A multidisciplinary effort will be needed to improve long-term patient outcomes in the evolving epidemiology of LB.\n\nID: 41988178\nTitle: From forest floor to doctor's office: the immunological journey of Borrelia burgdorferi through vertebrate hosts.\nAbstract: Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most prevalent vector-borne infection in the Northern Hemisphere and continues to expand geographically. Although B. burgdorferi has a streamlined genome and minimal virulence repertoire, it establishes persistent infection through coordinated modulation of mammalian host immune responses. Here, we synthesize recent advances in the immunobiology of B. burgdorferi using a stage-structured framework that traces a tick-mediated vertebrate infection through systemic dissemination, tissue colonization, and chronic immune engagement. Emphasis is placed on post-2020 insights enabled by intravital imaging, single-cell transcriptomics, spatial profiling, and systems immunology, which have refined our understanding of endothelial transmigration, tissue-specific immune conditioning, disruption of germinal center responses, and failure of sterilizing immunity. We highlight how antigenic variation at the vls locus, complement evasion, and coordinated adhesin networks support dissemination and long-term tissue residency, while adaptive immune responses are redirected toward extrafollicular, non-sterilizing trajectories. These immune strategies differentially shape infection outcomes across host species, supporting asymptomatic persistence in reservoir hosts while driving inflammatory disease in humans. The review further examines antigen persistence, immune stalemate, and post-treatment inflammatory sequelae, integrating translational advances in diagnostics and prevention. By integrating an ecological context with mechanistic immunology and clinical insight, this review presents a contemporary framework for understanding how immune modulation by B. burgdorferi across spatial and temporal scales shapes host-pathogen coevolution and informs improved diagnostic strategies, vaccine development, and therapeutic intervention.\n\nID: 41972549\nTitle: In Silico-Identified Peptides of Five Borrelia burgdorferi Proteins Binding with High Affinity to Human Leukocyte Antigen (HLA) Class II Alleles.\nAbstract: To date, Lyme vaccine development has largely overlooked the vaccinee's human leukocyte antigen (HLA) genetic makeup on which antibody production critically depends. Here, we evaluated in silico the predicted binding affinities of 192 HLA-II alleles with all 15-mer peptide sequences of five Borrelia burgdorferi proteins to identify peptides with strong binding affinity, as they would be the best candidates for antibody production in response to vaccination. We found the following: (a) 226 of the 1067 peptides tested (21.2%) were found to bind strongly to HLA-II molecules; (b) decorin-binding protein A had the greatest number of strongly binding peptides; and (c) 69 HLA-II alleles (primarily of the DRB1 gene) bound with strong affinity to peptides from Borrelia burgdorferi proteins. Finally, we tested for possible susceptibility to autoimmunity by any one of the 226 peptides above by searching for their occurrence in ~84,000 proteins of the human proteome and found overlap with only two 8-mer peptide sequences (embedded within the 226 15-mer peptides), neither of which was characterized by strong binding to HLA-I, suggesting a reduced likelihood of autoimmunity. These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety. The results of this computational study provide novel directions for future development of Lyme vaccines.\n\nID: 41845441\nTitle: Efficacy of Revolution\u00ae Plus (selamectin plus sarolaner) for the prevention of transmission of Borrelia burgdorferi from infected Ixodes scapularis to cats.\nAbstract: Borrelia burgdorferi and Anaplasma phagocytophilum are transmitted by Ixodes spp., with antibodies having been detected in cats in endemic areas. The combination of selamectin plus sarolaner (Revolution\u00ae Plus/Stronghold\u00ae Plus; Zoetis; RP) is effective against Ixodes spp. for 1 month. The objective of this study was to determine whether RP protects cats against transmission of B. burgdorferi from Ixodes scapularis by killing the ticks before transmission occurs. Transmission of A. phagocytophilum was also monitored. Ten cats per group were treated once topically either with placebo solution (0.1\u00a0ml/kg) or with the minimum label dose of RP (6.0\u00a0mg/kg selamectin plus 1.0\u00a0mg/kg sarolaner). Thirty days post-treatment, cats were infested with 50 wild-caught adult I. scapularis. Ticks were counted, categorized, and removed on day 35. Blood collections for serology occurred on days -6, 30 (prior to infestation), 49, 63, 77, 91, and 104. Serum antibody assay results (B. burgdorferi and A. phagocytophilum) and polymerase chain reaction (PCR) of skin biopsies (B. burgdorferi) were used to define infection rates in the cats. Treatment with RP resulted in a 100% reduction of I. scapularis ticks compared with placebo-treated cats. In placebo-treated cats, antibodies against B. burgdorferi, A. phagocytophilum, both agents, and B. burgdorferi DNA in skin (five, nine, six, and three cats, respectively) were detected by day 104. In contrast, none of the RP-treated cats developed B. burgdorferi antibodies or DNA in skin biopsies, and A. phagocytophilum antibodies were detected in only two cats, significantly lower than in placebo-treated cats. Results suggest that a single application of RP at the minimum label dose reduces the risk of infection by both B. burgdorferi and A. phagocytophilum, when infected at the end of the dosing interval.\n\nID: 41826406\nTitle: Evaluation of immunoreactive epitopes in the sera and cerebrospinal fluid of patients with post-treatment Lyme disease syndrome.\nAbstract: While most patients fully recover after treatment for Lyme disease with recommended antibiotic regimens, some report non-specific symptoms after treatment. When these symptoms are unexplained by other conditions and persist for \u2265\u20096 months, this condition is called post-treatment Lyme disease symptoms or syndrome (PTLDS). The pathogenesis of PTLDS is unknown and no specific diagnostic biomarkers have been identified. In this study, we used a high-density peptide array to examine antibody responses to >\u200960 primary antigens of B. burgdorferi from a cohort of patients diagnosed with PTLDS and recovered patients with similar Lyme disease manifestations. Using matched serum and cerebrospinal fluid (CSF), we mapped the primary reactive B. burgdorferi epitopes associated with PTLDS. We found that VlsE had a greater antibody response within the PTLDS cohort than recovered patients. The reactivity to OspC-specific epitopes revealed a predominance of antibodies to OspC type K and A in the PTLDS cohort. However, the major immunodominant epitopes were similar in PTLDS and recovered patients, and we were unable to identify specific diagnostic targets for PTLDS. We found a more robust reactivity in the serum over CSF and did not identify antigenic regions that were specifically associated with the infection of the central nervous system.\n\nID: 41808193\nTitle: Efficacy of Simparica and Simparica TRIO for the prevention of Borrelia burgdorferi by Ixodes scapularis.\nAbstract: Both Simparica\u00ae and Simparica TRIO\u00ae chewable tablets are efficacious within 12\u00a0h against existing Ixodes scapularis infestations and within 24\u00a0h against re-infestations for 1 month. It is therefore expected that treatment with either product prevents Lyme infections due to their efficacy against I. scapularis ticks before the anticipated transmission of Borrelia burgdorferi by infected ticks. In total, four laboratory studies were conducted in which dogs were randomly allocated to two treatment groups of 10 dogs each. On day 0, dogs were either administered a placebo treatment (Pet-Tabs\u00ae Palatable Vitamin-Mineral Supplement for Dogs), Simparica TRIO tablets at the minimum dose of 1.2\u00a0mg/kg sarolaner, 24\u00a0\u03bcg/kg moxidectin and 5\u00a0mg/kg pyrantel (study 1 and 2) or Simparica at the minimum dose of 2\u00a0mg/kg sarolaner (study 3 and 4). On post-treatment day 28, each dog was infested with approximately 50 unfed, wild-caught adult I. scapularis ticks with a high B. burgdorferi infection rate. Blood samples were collected from each prior dog to treatment and on post-treatment days 27, 49, 63, 77, 91 and 104, and qualitatively tested for B. burgdorferi antibodies using the SNAP\u00ae 4Dx Plus and Lyme Quant C6\u00ae antibody tests. Four skin biopsies from each dog were collected on day 104 from the most common areas of tick attachment and tested by PCR for the quantitative presence of B. burgdorferi. In all studies, at least nine out of 10 placebo-treated dogs were infected with B. burgdorferi before the end of the study. In study 1, one Simparica Trio-treated dog tested positive, whereas in the other studies none of the dogs treated with sarolaner tested positive at any time point during the study. Both Simparica and Simparica Trio at the minimum label dose prevent the transmission of B. burgdorferi infections as a direct result of killing the I. scapularis vector ticks.\n\nID: 41796643\nTitle: Feasibility and preliminary efficacy of an online yoga program for managing symptoms of post-treatment lyme disease syndrome.\nAbstract: We evaluated the feasibility and efficacy of a 12-week synchronous online yoga program for managing post-treatment Lyme disease syndrome (PTLDS) symptoms, focusing on pain, physical functioning, and cognitive performance. Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms.\n\nID: 41653328\nTitle: Sex and menopause-based differences in presentation of early Lyme disease: A prospective cohort study.\nAbstract: Although prior research has established sex and menopausal status-based differences in immune response, susceptibility, and severity to a variety of pathogens, their relevance in early Lyme disease is understudied. We examined the clinical and serologic presentation of patients with early Lyme disease, stratified first by sex then by menopausal status. We also explored the hypothesis that males would present with more severe early Lyme disease. In this prospective cohort study from the Mid-Atlantic US, 243 adult, antibiotic-na\u00efve patients were enrolled with a diagnostic erythema migrans rash present. Demographic, physical exam, symptom, laboratory, and two-tier serology data were collected at a baseline, and a post-treatment visit 3 weeks later. Lyme disease severity was operationalized through six indicators: rash size, number of acute symptoms, dermatologic dissemination, positive serology, liver function elevation, and elevated neutrophil-lymphocyte ratio. Unadjusted group comparisons and multivariate regression adjusting for potential confounders were used to assess difference. In logistic models adjusted for age, Lyme disease duration, systemic steroid use, and co-morbid thyroid disease, males had higher odds of testing two-tier positive (OR\u2009=\u20091.77 [1.03, 3.04], p\u2009=\u20090.039). This difference was more pronounced between males and pre-menopausal females (OR\u2009=\u20092.93 [1.26-6.79], p\u2009=\u20090.012) and no significant difference was found comparing males to post-menopausal females. In ordinal logistic models with Lyme disease severity as the outcome adjusted for age and Lyme disease duration, males had higher odds of being in a higher disease severity score category (OR\u2009=\u20091.94 [1.20,3.15], p\u2009=\u20090.028); again, particularly in comparison to pre-menopausal females (OR\u2009=\u20092.26 [1.13,4.58], p\u2009=\u20090.044). Heart palpitations (p\u2009=\u20090.023), vomiting (p\u2009=\u20090.007), and photophobia (p\u2009=\u20090.057) trended towards higher reporting among females, while sleep difficulty (p\u2009=\u20090.010) was higher among males. No differences were found on non-dermatologic components of the physical exam.\u00a0We found sex and menopausal status to be relevant in accounting for variability in two-tier serologic status and severity of early Lyme disease in a well-characterized group of patients. Lower rates of seroreactivity among females is unexpected but may be consistent with lower acute severity of disease. Our clinical findings underscore the need for additional research to understand possible contributing biologic and/or social behavioral factors, as well as their impact on timely diagnosis and post-treatment conditions. Lyme disease is a bacterial infection obtained through a tick bite. The goal of this study was to look at whether male and female patients with early Lyme disease show up to the doctor with different signs of their disease in terms of the symptoms they report, their physical exams, and the results of their laboratory tests. We also examined whether females who had gone through menopause would be different on these factors compared to those who had not. We studied data from 243 adults (118 females and 125 males) with early Lyme disease before and after treatment. We found that at diagnosis, males were more likely to have a positive test and more obvious findings of severe disease, yet there were no differences in how long males and females had been sick. For both of these findings, the male group was more similar to females who had undergone menopause and was more different than females who had not. We found a small number of Lyme disease symptoms that were reported more frequently among females (heart palpitations, vomiting, eyes sensitive to light, neck pain, nausea) and two symptoms (sleep difficulty and irritability) reported more frequently among males. These findings suggest that sex and menopause status are important to consider in understanding early Lyme disease. More research is needed to determine the cause of these differences and their impact on time to diagnosis and risk of later conditions after treatment.\n\nID: 41570190\nTitle: Nonspecific Symptoms Attributable to Lyme Disease in High-Incidence Areas, United States, 2017-2021.\nAbstract: For some patients who have Lyme disease (LD), nonspecific symptoms can persist after treatment and impair quality of life. Estimating the frequency and duration of such symptoms is challenging. Using commercial insurance claims data from 2017-2021 for enrollees residing in states where LD is common, we identified 24,503 case-patients with LD and matched them (1:5) with 122,095 control-patients with other diagnoses by demographics, medical service date, and inpatient/outpatient setting. We compared relative frequencies of diagnosis codes for pain, fatigue, and cognitive difficulties between case-patients and control-patients in the year after diagnosis. Those symptom codes occurred 5.0% more frequently among case-patients than among control-patients and comprised \u00bb11.0% of the total symptom codes among case-patients. Symptom code frequency among case-patients declined significantly in the 6-12 months after LD diagnosis and reached levels similar to control-patients by the end of the year, with the exception of fatigue.\n\nID: 41421419\nTitle: Methemoglobinemia induced by dapsone, hydroxychloroquine, and rifampin combination for post-treatment Lyme disease syndrome: A case report.\nAbstract: A patient presented to the emergency department with drug-induced methemoglobinemia due to a combination of medications prescribed for post-treatment Lyme disease syndrome (PTLDS). This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination.\n\nID: 41314472\nTitle: Guidelines for Lyme borreliosis: post-treatment Lyme disease syndrome (PTLDS).\nAbstract: Persistent symptoms following appropriate treatment of confirmed Lyme borreliosis (LB) require a systematic clinical reassessment. The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences.\n\nID: 41310474\nTitle: Prevalence and clinical characteristics of Norwegians who report persistent health complaints attributed to tick bites or tick-borne diseases.\nAbstract: Persistent symptoms attributed to tick bites or tick-borne diseases are poorly understood. We estimate regionally adjusted prevalence of persistent symptoms, investigate seroprevalence (IgG) and ongoing infections, and examine associated demographic and clinical factors. Persons aged 18 years or older with persistent symptoms lasting six months or more attributed to tick bites or tick-borne diseases, were recruited into a nationwide cross-sectional study. Demographic data were recorded. Medical records were collected (February 2020 - April 2022) and reviewed for tick bites, tick-borne infections, antibiotic treatment, and clinical findings. Outcome measures included somatic symptoms (PHQ-15), fatigue (Fatigue Severity Scale), physical health (RAND-36), and affective symptoms (HAD Scale). Laboratory assessments included polymerase chain reaction (PCR) analysis of blood samples for Borrelia burgdorferi (Bb) and other known tick-borne pathogens, along with IgG antibody detection. The highest prevalence of persistent symptoms attributed to tick bites or tick-borne diseases was found in southwestern Norway (0.152-0.155%); the lowest was in the north (0.033%), which also had significantly lower Bb-IgG seroprevalence (15.4% compared to the national average 37.5%). Symptom persistence was not associated with confirmed tick exposure or tick-borne infection. Somatic symptoms were associated with low physical activity and comorbidity. Fatigue and poor physical health were strongly associated with underemployment. Fatigue was also associated with depressive symptoms, low activity, sick leave, and comorbidities. Persistent symptoms were most prevalent in tick-endemic regions but were not associated with prior tick exposure or tick-borne infections. Symptom burden was primarily associated with comorbidities, especially physical inactivity and underemployment. Not applicable.\n\nID: 41195425\nTitle: Guidelines for diagnosis and treatment in neurology - Lyme neuroborreliosis.\nAbstract: Lyme disease is the most common tick-borne infectious disease in Europe. Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor. Im Rahmen eines systematischen Reviews zur Therapie des sogenannten Post-Treatment Lyme Disease Syndrome (PTLDS) zeigte sich, dass die untersuchten Parameter Lebensqualit\u00e4t, Fatigue, Depression und Kognition nicht auf eine antibiotische Therapie ansprechen. F\u00fcr die Wirksamkeit anderer Therapieverfahren fanden sich keine aussagekr\u00e4ftigen Studien.\n\nID: 41168716\nTitle: Understanding the complexity of cutaneous leishmaniasis patient journey in endemic rural Sri Lanka: a qualitative study.\nAbstract: The experiences of patients and healthcare providers are fundamental in understanding the patient journey, particularly in the context of neglected diseases affecting rural populations. These insights are crucially important for advancing people-centred, high-quality healthcare and achieving improved health outcomes. Cutaneous leishmaniasis (CL) causes chronic, disfiguring skin lesions leading to a significant burden on the affected communities and the health systems. Our study aims to examine the experiences of people with CL after entering the biomedical healthcare system. We also integrate these findings with our previous work to map the entire CL patient journey in a disease-endemic district in Sri Lanka. We conducted a qualitative study in three rural communities with high disease prevalence in the Anuradhapura district, Sri Lanka. We collected data through (1) a participant experience reflection journal (PERJ), (2) post-PERJ interviews and (3) an interview study with healthcare professionals. We analysed data through thematic analysis. Thirty PERJs were completed by individuals with CL, with 25 participating in post-PERJ interviews and 16 healthcare professionals participated in the key informant interviews. Upon entering a biomedical healthcare facility, a person with CL navigated through the stages of clinical suspicion and laboratory diagnosis, receiving treatment and achieving a cure (as clinically confirmed by the treating dermatologist). Although many physicians accurately suspected cases upon initial presentation, some failed to clinically diagnose CL promptly. Some patients experienced prolonged waiting times for their initial consultations with the dermatologist and to receive diagnostic test results. Accessibility issues, travel and meal costs, and competing responsibilities like household work, education, and employment further added to the burden of attending frequent clinic visits for CL. Despite the long and painful nature of the treatment, compliance among people with CL remained satisfactory, with rare reports of treatment failure. For some people, the CL patient journey extends beyond the clinically defined cure, as they continue to live with constant fears, perceived physical impacts associated with the disease, and effects of treatment. We found that, despite certain positive aspects, the CL patient journey is complex, with substantial and pervasive delays and barriers along with psychosocial impacts that persist beyond clinical cure. Our study findings can inform evidence-based, context-specific interventions to reduce the public health burden of CL in resource-limited settings.\n\nID: 41136524\nTitle: HLA and pathogens in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and other post-infection conditions.\nAbstract: Viral infections have been widely implicated in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) pathogenesis. Recent evidence has also identified certain Human Leukocyte Antigen (HLA) alleles that are significantly associated with ME/CFS risk/protection. Here we tested the hypothesis that ME/CFS risk or protection conferred from those HLA alleles is associated with binding affinity to antigens of HHV viruses, a critical step in initiating the adaptive immune system response to foreign antigens. Specifically, we determined in silico the predicted binding affinity of two susceptibility alleles (C*07:04, DQB1*03:03) and two protective alleles (B*08:01, DPB1*02:01) to >\u200910,000 antigens of the 9 Human Herpes Viruses (HHV1, HHV2, HHV3, HHV4, HHV5, HHV6A, HHV6B, HHV7, HHV8) which have been implicated in the etiology of ME/CFS. We found that the binding affinity of all HHV antigens to the susceptibility alleles was significantly weaker than the binding affinity to the protective alleles (P\u2009<\u20090.001). In fact, none of the HHV antigens showed strong binding to the susceptibility alleles, in contrast to the strong bindings showed by the protective alleles. These findings are in keeping with the hypothesis that the effect of a putative HHV insult in contributing to ME/CFS is modulated by the host's HLA immunogenetic makeup. We speculate that strong HLA-antigen binding likely protects against ME/CFS via elimination of virus antigens; conversely, weak HLA-antigen binding may permit persistence of foreign antigens, contributing to ME/CFS and other chronic conditions. Finally, with respect to the latter, we determined the binding affinities to the 4 HLA alleles above to pathogens causing two chronic diseases with very similar symptomatology to ME/CFS, namely Long COVID and post-treatment Lyme disease syndrome (PTLDS). We found that the 2 ME/CFS susceptibility HLA alleles above had very weak binding with SARS-CoV-2 virus glycoprotein (involved in Long COVID) and 5 proteins of Borrelia burgdorferi (involved in PTLDS), in contrast to the ME/CFS protective alleles that showed strong bindings. These findings support the hypothesis that ME/CFS, long COVID and PTLDS are caused by persistent pathogenic antigens that could not be eliminated due to inadequate protection by the patient's HLA makeup.\n\nID: 41065377\nTitle: The multiplexed single-tier InBios Lyme Detect Multiplex ELISA is more sensitive than standard two-tier tests in the early stages of Lyme disease.\nAbstract: There are nearly 500,000 cases of Lyme disease each year in the United States; 10%-20% of them result in the development of a debilitating chronic disease known as post-treatment Lyme disease. Existing standardized and modified two-tier tests (STT/MTT) suffer from poor detection rates in the first weeks of infection, where the antibody response, the basis of diagnosis, is developing but is not robust enough for detection. During this early window, false negative results are common, which leads to delayed treatment and increases the likelihood of developing severe symptoms. The InBios Lyme Detect Multiplex ELISA is a microarray-based assay designed to capture a set of commonly used diagnostic antibodies specific to Borrelia burgdorferi from human serum. The multiplex array captures common diagnostic antibodies, including those to C6, VlsE, and OspC, and has in-line controls. Diagnostic index scores are calculated from the relative abundance of controls and antibodies using a proprietary machine learning algorithm. The assay was evaluated here for reproducibility, accuracy, and performance. It was found to be reproducible using a group of 30 samples run in triplicate. The assay performed well in a blinded panel, correctly identifying all standard two-tier test-positive samples and controls while also detecting 21 of 79 samples that were clinically diagnosed but undetectable by standard Lyme serologic tests. There was one false positive from 66 look-alike disease samples and 146 healthy controls. The InBios assay has the potential to improve diagnostic sensitivity within the early weeks of infection while matching the specificity of current diagnostic tests. During initial Lyme disease infection, existing diagnostic tests have poor sensitivity, resulting in a high number of false-negative tests. This is due to the lag between infection and a robust immune response capable of being detected by such tests. With a multiplexed array of nine unique antibody targets specific for Borrelia burgdorferi, interpreted by a proprietary machine learning algorithm, the InBios Lyme Detect Multiplex ELISA has the potential to increase diagnostic sensitivity within the first few weeks of infection, reducing the number of false-negative tests. Improving diagnostic sensitivity during early infection would reduce the risk of developing severe symptoms, including post-treatment Lyme disease.\n\nID: 41024925\nTitle: Reassessing Chronic Lyme Disease and Post-Treatment Lyme Disease Syndrome as Focal Infections.\nAbstract: The complete clinical spectrum of Lyme borreliosis has been recognized for nearly 50 years, yet its diagnosis remains challenging due to the heterogeneity of symptoms. While many symptoms are likely nonspecific, a recurring cluster, including severe fatigue, brain fog, cognitive decline, memory impairment, joint and muscle pain, limb numbness, headaches, and low-grade fever, is often labeled in the scientific literature as post-treatment Lyme disease syndrome (PTLDS), and in the popular media as \"chronic Lyme disease.\" Based on clinical experience and retrospective case analysis, this study hypothesizes that in many such cases, these persistent symptoms are not sequelae of Lyme borreliosis but manifestations of an undiagnosed focal infection, most commonly chronic tonsillitis or periodontal disease. The hypothesis is supported by the observation that the symptom profile of PTLDS is remarkably similar to that seen in focal infections, and by documented patient outcomes following treatment of these localized infections. This study compiles and analyzes clinical data to support the reinterpretation of PTLDS and \"chronic Lyme disease\" as misattributed focal infections in a subset of patients.\n\nID: 40985958\nTitle: Evidence-Based Clinical Effectiveness of Kundalini Yoga: Systematic Review of RCTs Across Multiple Health Conditions.\nAbstract: Kundalini Yoga (KY) integrates breathwork, meditation, dynamic movement, and chanting, and has gained recognition as a therapeutic intervention. Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes. KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions. However, larger, standardized RCTs with active comparators, biomarkers, and longer follow-up are needed.

Disulfiram (DIS), a drug for alcoholism, is under investigation as a potential adjunctive treatment, but its low bioavailability, rapid metabolism, and safety concerns urge the development of improved formulations for clinical translation. Methods: Screening dissolution and permeation studies were investigated for vehicle and excipient selection, following the pharmacopeia perspectives to develop and optimize the low-dose DIS rectal suppository intended for application in post-treatment Lyme disease syndrome (PTLDS). Further characterizations were carried out by differential scanning calorimetry, X-ray diffraction, and infrared spectroscopy. Results: Cyclodextrin (CD) encapsulation was investigated to improve the aqueous solubility of the hydrophobic drug. The dissolution of DIS from fatty base suppository was very slow; it was remarkably improved by the molecular encapsulation of the drug with CDs. The dissolution of DIS from a water-soluble base was more favorable, but incomplete. In the polyethylene glycol (PEG) based suppositories, the addition of CDs already in a physical mixture ensured the dissolution of the drug. The presented drug delivery system relates to a novel preparation for rectal administration comprising a low-dose disulfiram with improved solubility and permeability by the PEG and hydroxypropyl-\u03b2-cyclodextrin (HPBCD) synergistic matrix. Conclusions: The rectal dosage form containing the drug and CD in the physical mixture is advantageous, avoiding the hepatic first-pass effect, minimizing dose-limiting toxicity, simplifying production, and fasting the availability of the repositioned drug.\n\nID: 40703523\nTitle: Aberrant T-cell phenotypes in a cohort of patients with post-treatment Lyme disease.\nAbstract: Post-treatment Lyme Disease (PTLD) is a poorly understood complication of Borrelia burgdorferi infection with significant patient morbidity. Characterized by fatigue, generalized myalgias, and cognitive impairment, PTLD symptomatology closely resembles long COVID and other post-acute infection syndromes. While prior studies suggest immune dysregulation as a factor in PTLD pathogenesis, the mechanisms underlying its heterogeneous presentation and severity remain unclear. To associate symptom burden with discrete immune phenotypes, we applied factor analysis to self-reported symptom data from 272 PTLD patients to generate patient subgroups. We then immunophenotyped peripheral blood cells of these individuals and 28 healthy controls through 19-parameter flow cytometry and cytokine profiling to associate PTLD status and the newly defined subgroups with specific immune states. Our PTLD cohort had fewer circulating CXCR5+ CD4+ na\u00efve T cells relative to healthy controls (5.2% vs. 8.3%, Padj < 0.001). These cells were positively associated with musculoskeletal pain in PTLD participants, but not healthy controls. This and additional immunophenotypic alterations, including an increased prevalence of CXCR3+ CCR4- CCR6- CD8 T cells (43.1% vs. 25.7%, Padj < 0.01), permitted the creation of an elastic net classifier which identified PTLD with moderate efficacy (AUC 0.83). Measurement of cytokines did not reveal associations with PTLD and did not improve the performance of the model. While we could not identify immune features which distinguished all patient subgroups, we did observe a female-specific increase in central memory CD8 T cells restricted to one high-fatigue patient subgroup. Additionally, factor analysis revealed multiple associations between immune cell frequency and the severity of specific symptoms. Collectively, our findings add to growing evidence of immune dysfunction as a prominent feature of PTLD.\n\nID: 40662763\nTitle: Class and isotype of VlsE-specific antibody differentiates Lyme disease stage.\nAbstract: Establishment of immunoglobulin diversity is contingent on recombination that occurs both at the Fab and at the Fc regions of the immunoglobulin, and this process is time dependent. Based on this principle, we questioned whether Lyme disease stage can be distinguished by quantification of immunoglobulin class and IgG isotype specific to VlsE in serum from clinically characterized patients. We used an enzyme immunoassay to categorize serologic antibodies to VlsE antigen as well as machine-learning techniques to train and integrate multiple predictors to identify likely disease stage. We found that IgM/IgG3/IgG1/IgA1 was enriched in serum obtained in the earliest stages, whereas IgG3/IgG1/IgG4 was enriched in Lyme arthritis. IgG2 detection was unremarkable across all disease stages. Post-Treatment Lyme Disease Syndrome (PTLDS) serum was enriched in IgG3/IgG1/IgA1 but lacked IgM. The multivariable models showed better predictive accuracy than any single immunoglobulin model, with more than half of panels perfectly identified by random forest under cross validation (56%) vs a maximum of 38% for a model using IgG1 alone. The findings suggest a characteristic succession of VlsE-specific antibody switching between immunoglobulin class and IgG isotype as Lyme disease progresses from early to late stages. The data also suggest that immunoglobulin class and IgG isotyping are likely more helpful to distinguish early Lyme disease cases. Comprehensive evaluation of immunoglobulin class (M, G, A) and IgG isotypes (1/2/3/4) provides time-dependent pathogen-induced host response information to current Lyme disease antibody detection and may be useful for differentiation of disease stage. The order of switching between the immunoglobulin heavy chain (Fc) is time dependent, progressing from IgM/D to IgG3/IgG1/IgA1/IgG2/IgG4 and later to IgE/IgA2. In this study, we show that B. burgdorferi-VlsE-specific antibody switching proceeds in a predictable sequence between class (Ig M/G/A) and IgG isotype (IgG 1/2/3/4) as Lyme disease progresses from early to late stage and that antibody class and isotype may be more helpful to distinguish the early stages of Lyme disease. This study advances our understanding of the tempo and structure of the humoral immune response to B. burgdorferi and is applicable to the development of new diagnostic assays for Lyme disease.\n\nID: 40511782\nTitle: Cycles of (Dis)engagement: A Qualitative Meta-Synthesis of the (Health)Care-Seeking Experiences of Patients with Chronic Symptoms Following Lyme Disease.\nAbstract: (Chronic) Lyme disease/post-treatment Lyme disease syndrome ([C]LD/PTLDS) is a post-infection illness that remains contested, resulting in a divergent epistemological landscape (i.e., biomedicine versus alternative medicine). Consequently, (C)LD/PTLDS patients exhaust their (health)care options in their search for symptom relief, falling into cycles of starting and stopping (health)care-seeking. This meta-synthesis reviewed 13 qualitative interview studies representing the (health)care-seeking experiences of 216 (C)LD/PTLDS patients across five countries (i.e., United States, Canada, Netherlands, Australia, France) to examine how communication catalyzes patients' (health)care-seeking behaviors. This study proposes a model of (health)care (dis)engagement, identifying communication as a motor moving patients through (health)care-seeking both within and outside of biomedical models of care. This model extends our understanding of communicative (dis)enfranchisement processes and understandings of why patients disengage and reengage in healthcare-seeking behaviors. Theoretical and practical implications and future directions are discussed.\n\nID: 40385877\nTitle: Prevalence of Rheumatoid Factor and Anti-citrullinated Protein Antibodies in Patients With Post-treatment Lyme Disease.\nAbstract: Post-treatment Lyme disease (PTLD) occurs in a portion of patients\u00a0after initial antibiotic treatment of Lyme disease (LD) and is often characterized by arthralgia without synovitis. Rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) are often used to assess joint pain in this setting; however, their clinical utility remains unknown. Our objective was to define the frequency of these autoantibodies in a large cohort of carefully characterized patients with PTLD meeting a research case definition and to determine the clinical implications of these tests.\u00a0RF and ACPA were tested as indicated clinically and abstracted by chart review. The prevalence of antibodies and their relationship to symptoms were examined. Of the 167 patients included in the analysis, RF status was documented at least once for 78.4% (131 of 167), and ACPA status was available at least once for 88.0% (147 of 167). RF was positive in 3.8% (five of 131), and ACPA was positive in 4.8% (seven of 147)\u00a0at least at one time point.\u00a0A total of 7.2% (12 of 167)\u00a0patients were found to have a positive RF or ACPA test at least at one time point.\u00a0There was no difference in the proportion of patients with RF and/or ACPA based on the initial presenting manifestations of their LD, nor the symptoms of PTLD at later evaluation; however, the small sample size may limit our ability to detect these clinical differences. We found a low prevalence of RF and ACPA in this study, similar to the known rates in the general population. This reflects the lack of inflammatory arthritis in this population with clinically defined PTLD and arthralgia only.\n\nID: 40354663\nTitle: Lyme Disease.\nAbstract: Lyme disease, caused by Borrelia burgdorferi, is the most common vector-borne disease in the United States, and the range of its tick vector continues to expand. Most Lyme disease cases are diagnosed with the onset of the erythema migrans rashes, which can be single or multiple and vary from a homogeneous erythema to bull's-eye patterns. Serologic antibody testing is of low sensitivity at onset but becomes highly sensitive after a few weeks. Early dissemination may lead to neurologic and cardiac complications. Mono- or oligoarticular arthritis may develop in untreated patients. Antibiotic treatment is highly effective, but approximately 10% of treated patients experience persistent symptoms.\n\nID: 42324826\nTitle: The current landscape and future directions of Lyme disease vaccines.\nAbstract: Lyme disease (LD) represents a significant public health challenge in North America and Eurasia. The persistent increase in its incidence may create an opportunity for vaccines to gain broader acceptance. Recent years have seen notable advances in vaccine development. However, achieving a balance between broad-spectrum protection and durable immunity remains a critical bottleneck. This article is presented as a narrative review that systematically summarizes recent progress in Lyme disease vaccine research worldwide, with particular emphasis on the strengths and limitations of approved and investigational candidates. Unlike existing reviews, this study integrates recent clinical investigations of multivalent vaccine candidates with breakthrough advances across diverse vaccine platforms, yielding a comprehensive and current synthesis. We identify critical challenges in contemporary vaccine development and propose actionable solutions. Our forward-looking perspective centers on a triangular strategy that integrates antigen multivalency, platform personalization, and geographical customization, providing a conceptual framework to guide future LD immunoprophylaxis research.\n\nID: 42308248\nTitle: Machine learning-driven identification of virulence determinants in Borrelia burgdorferi associated with human dissemination.\nAbstract: Lyme disease, the most common tick-borne infectious disease in the United States, presents with highly variable clinical outcomes, ranging from localized erythema migrans to severe disseminated complications affecting the heart, joints, and nervous system. The bacterial determinants underlying this phenotypic variation remain largely unknown, limiting our ability to predict disease progression and optimize treatment strategies. Here, we applied machine learning (ML) approaches to identify specific amino acid residues within surface-exposed virulence factors that predict human dissemination phenotypes. Utilizing the published whole genome sequences from 299 clinical Borrelia burgdorferi isolates collected from the United States and Slovenia over a 30-year period (1992-2021), we extracted and characterized translated amino acid sequences (variants) of seven known virulence factors (BB_0406, BBK32, DbpA, OspA, OspC, P66, and RevA). Protein variants were classified based on their association with disseminated versus localized infections using clinical metadata. Cram\u00e9r's V analysis revealed possible strong associations between dissemination phenotypes and five adhesins: BBK32, DbpA, OspC, P66, and RevA. We developed ML models using five algorithms with multiple feature selection strategies, achieving robust predictive performance for DbpA, OspC, and RevA variants (all performance metrics\u2009>\u20090.7). Feature importance analysis identified 57, 29, and 42 key predictive residues for DbpA, OspC, and RevA, respectively. Notably, B-cell epitope prediction revealed significant enrichment of ML-identified residues within predicted epitope regions for OspC (11 overlapping residues, OR = 3.57, p\u2009=\u20090.006) and RevA (12 overlapping residues, OR = 2.37, p\u2009=\u20090.048), suggesting these residues may influence immune recognition and bacterial persistence. This study establishes the first computational framework linking Borrelia protein sequence variants to clinical dissemination phenotypes, providing molecular insights into Lyme disease pathogenesis that may inform the development of improved diagnostics and therapeutic targets.\n\nID: 42007715\nTitle: Coinfection ecology and pathogen emergence in a Borrelia-endemic landscape: 5 years of Borrelia burgdorferi, Anaplasma phagocytophilum, and Babesia microti surveillance in Maryland.\nAbstract: The emergence of tick-borne pathogens depends on ecological opportunity and barriers to persistence within vectors and hosts. Borrelia burgdorferi is well established in the mid-Atlantic, whereas Babesia microti and Anaplasma phagocytophilum remain patchily distributed. Five years of integrated surveillance (2020-2024) at three Maryland sites allowed us to track B. microti and A. phagocytophilum establishment by screening questing Ixodes scapularis nymphs, Peromyscus leucopus-fed nymphs, and P. leucopus samples by qPCR, contextualized with county-level human case data. B. burgdorferi was consistently detected in all sites and sample types, with prevalence generally 5%-20% in questing nymphs and exceeding 30% in hosts, confirming long-term enzootic maintenance. By contrast, B. microti and A. phagocytophilum were initially sporadic but increased in rodents and P. leucopus-fed ticks. Over time, A. phagocytophilum prevalence significantly increased to above 20% in some P. leucopus-fed nymphal collections despite much lower prevalence in questing ticks, highlighting the early-warning value of blood meal-associated surveillance. Notably, B. microti reached very high prevalence in P. leucopus hosts at a specific site (up to ~80%) while remaining rare or absent in questing and engorged nymphs, highlighting a pronounced decoupling between host infection and vector prevalence. Coinfections were rare, though enrichment of B. burgdorferi + A. phagocytophilum in P. leucopus-fed ticks suggests possible facilitation during early establishment. These results indicate that B. microti and A. phagocytophilum are actively emerging in Maryland, following their establishment in the Northeast and Upper Midwest. Combining surveillance from questing nymphs, P. leucopus-fed nymphs, and reservoir hosts provides a framework for detecting enzootic cycles before they appear in questing ticks or human case counts, offering early-warning capacity for public health preparedness.IMPORTANCEUnderstanding why some tick-borne pathogens become ecologically established while others remain sporadic is central to predicting human disease emergence. By combining surveillance of questing nymphal Ixodes scapularis ticks, Peromyscus leucopus-fed nymphal ticks, and Peromyscus leucopus reservoir hosts across 5 years in Maryland, we show that Babesia microti and Anaplasma phagocytophilum remain in the early stages of enzootic establishment, whereas Borrelia burgdorferi is deeply established. This integrated approach demonstrates how pathogen biology within the tick shapes field prevalence and highlights P. leucopus-fed ticks as a powerful xenodiagnostic early-warning tool for detecting emerging pathogens before they are reflected in questing populations or human case data.\n\nID: 42003617\nTitle: Innate immune responses to Borrelia burgdorferi during tick-feeding: mechanistic insights relevant to Lyme disease.\nAbstract: Immune responses to tick-transmitted Borrelia burgdorferi (Bb) have not been characterized in vivo. We analyzed the reservoir host's local and systemic immune responses to Bb during tick feeding. C3H/HeN mice were challenged via infected or uninfected nymphal Ixodes scapularis ticks or by subcutaneous injection of cultured multi-strain Bb. Skin and spleen tissues were evaluated by flow cytometry, serum was evaluated by cytokine proteome array, and all data were analyzed by comparison between each of the three challenged groups against the subcutaneously inoculated PBS control. Flow cytometry profiling shows that neutrophils, Langerhans cells, macrophages, B cells, and Natural Killer cells were mobilized in the three challenged groups in the skin and spleen, dendritic cells were increased in tick-transmitted groups, and T cells were engaged in Bb-challenged groups. Regarding soluble chemotaxis mediators in blood, all chemokines and cytokines induced by subcutaneously delivered Bb and uninfected tick were also induced by tick-transmitted Bb. However, tick-transmitted Bb induced unique factors absent in the other groups, which included chemokines involved in recruitment of phagocytic cells and T cell engagement, and cytokines associated with broader T cell activation. Regarding anti-inflammatory mediators, although IL-1ra was increased in the three challenged groups, IL-10 was only increased in tick-challenged groups with or without Bb. The data suggest that tick-transmitted Bb induced much more dynamic but regulated immune responses during tick-feeding, compared to subcutaneously delivered Bb, which may explain Bb persistence in the reservoir host.IMPORTANCECurrent knowledge on immune cell interactions with Borrelia burgdorferi (Bb) derives mostly from studies done in vitro and ex vivo, which cannot assess host immunity to natural tick-delivered Bb within the complex architecture of host tissues. We report the first in vivo study on local and systemic immune responses to Bb during tick feeding on a surrogate reservoir host, in comparison with uninfected-tick and subcutaneously delivered Bb. We show that uninfected-tick and tick-transmitted Bb engaged mixed type-1/type-2/type-17 immune responses in the presence of anti-inflammatory IL-10, in contrast to a type-1 response induced by subcutaneously delivered Bb. Analyses of immune responses to tick-transmitted Bb in a reservoir host can enlighten immunity mechanisms that mediate persistence of Bb.\n\nID: 41939499\nTitle: The Role of Borrelia Burgdorferi in the Etiology of Chronic Urticaria.\nAbstract: Lyme borreliosis/European borreliosis (LB/EB) is a multisystemic infection caused by the bacterium Borrelia burgdorferi, which is transmitted to humans by the bite of ticks and other hematophagous insects. Transmitted borrelia can occupy any organ where it causes a silent inflammation, which in sensitive persons is intermittently repeated chronically. The aim of this paper was to determine how much Borrelia burgdorferii participates in the occurrence of chronic urticaria in children and adults. In the 13-year period from January 1, 2013 to December 31, 2025, a study of all manifestations of Lyme borreliosis was conducted on a sample of 1,059 patients, treated and monitored in the Private practice of an infectious disease specialist. The research was retrospective-prospective, descriptive, clinical and analytical. It was carried out in three phases: the first retrospective phase and the second two prospective phases. The diagnosis of LB was established on the basis of anamnestic-epidemiological data, clinical picture, clinical findings of new borreliosis markers and performed examinations. Serological confirmation of borreliosis was done using ELISA, WB and Immunoblot methods, as well as the ex-yuvantibus method, and in the last six months of 2025, additionally, the finding of bacteria Borreliosis in a dark field with a light microscope. The results showed that 92.1% of the patients in the study group had intermittent migratory redness with itching. In the majority of patients, redness was without exudation or with little or no exudation. In 4.8% of patients, typical urticarial changes were found that occurred occasionally or daily. In all subjects, we serologically confirmed the presence of Borrelia burgdorferi. All patients had intermittent itching of the skin, which lasted for years. Based on the results, it can be concluded that Borrelia burgdorfrii is one of the most important factors in the development of chronic urticaria in monitored patients with 96.9%. Due to its persistence in the macroorganism, it causes reduced tolerance to food. Only 3.1% of cases of urticaria are caused by some other factors. In all cases of chronic urticaria, new clinical markers should be sought on the patients' skin. Serologically look for antibodies to Borrelia protein sequences in an immunoblot. In the active phase, look for Borrelia with a light microscope in the dark field. Administer antibiotic therapy together with antihistamines. Exclude food to which the intolerance test confirmed hypersensitivity greater than \"2\".\n\nID: 41859106\nTitle: Treponema pallidum TprD and TprK are adhesins and their surface expression promotes spirochetal opsonophagocytosis.\nAbstract: Treponema pallidum subspecies pallidum causes systemic syphilis, exclusively infects humans in nature and can persist for decades in the absence of treatment despite generating robust adaptive immune responses. The T. pallidum repeat (Tpr) family of outer membrane proteins are immunogenic and are implicated in immune evasion, indicating them to be virulence factors displayed on the spirochete surface. Long-term survival of T. pallidum is largely attributed to sparse surface-exposed outer membrane proteins and antigenic variation in the major surface protein TprK through phase variation. This mechanism has been studied for decades; however, the functions of Tprs of this extracellular pathogen are not yet experimentally determined. In this study, the localization and functional roles of TprD and TprK were investigated using a heterologous spirochete expression system and a gain-of-function approach by employing a non-infectious, non-adherent Borrelia burgdorferi B314 strain. Opsonophagocytosis of engineered B. burgdorferi as well as of T. pallidum Nichols and SS14 strains was evaluated using J774A.1 macrophages and mouse antibodies raised against predicted surface-exposed loops of TprD and TprK using IncuCyte system. Both TprD and TprK were found to be surface exposed in engineered B. burgdorferi and infectious T. pallidum strains. Expression of these proteins conferred adherence to several mammalian cell lines in vitro. In addition, antibodies we generated recognized TprD and TprK on the surface of spirochetes and significantly enhanced macrophage-mediated opsonophagocytosis. Our findings here demonstrate that TprD and TprK function as T. pallidum adhesins that are also targets of opsonic antibodies. These Tprs likely facilitate tissue colonization during infection, while also rendering the pathogen susceptible to immune clearance. Our findings support inclusion of TprD and TprK as components of a multivalent vaccine against syphilis.\n\nID: 41790564\nTitle: Association between spirochaetal infection and neurodegenerative diseases: a systematic review and quantitative synthesis of observational studies.\nAbstract: Introduction. Neurodegenerative diseases, including Alzheimer's and Parkinson's, are a growing global health concern. While age remains the primary risk factor, infectious agents have been proposed as potential contributors to disease onset or progression.Gap statement. Spirochaetal bacteria, such as Treponema pallidum, Borrelia burgdorferi and Leptospira spp., can invade the central nervous system, yet the extent to which these infections influence neurodegenerative outcomes remains unclear.Aim. This systematic review aimed to evaluate observational evidence on the association between spirochaetal infections and neurodegenerative diseases and to identify gaps in the literature to inform future research.Methodology. A systematic search of SCOPUS, EMBASE, PubMed/MEDLINE, Web of Science and CINAHL was conducted for studies published between January 2000 and May 2025. Eligible studies were observational, involved adult human populations and reported both spirochaetal infection and cognitive or neurodegenerative outcomes using standardized methods. Data were extracted using a standardized form. Owing to heterogeneity in study design, diagnostic approaches, outcome measures and reporting formats, an overall pooled meta-analysis was not feasible; however, a quantitative synthesis using meta-analytic methods was conducted for studies reporting mini-mental state examination data. Risk of bias was assessed using the Newcastle-Ottawa Scale.Results. Twenty-seven studies met the inclusion criteria: 13 on T. pallidum, 13 on B. burgdorferi and one on Leptospira spp. No eligible studies were found for Brachyspira spp., and studies involving Treponema denticola were excluded due to confounding by periodontitis. Studies investigating syphilis and leptospirosis consistently reported cognitive impairment and increased dementia risk. In contrast, findings for Lyme disease were heterogeneous, with some studies reporting persistent symptoms or increased Alzheimer's risk, while others found no long-term cognitive effects.Conclusion. This review highlights a potential link between spirochaetal infections and neurodegenerative outcomes, particularly for syphilis and leptospirosis. Evidence for Lyme disease remains inconclusive. Future research should prioritize longitudinal studies with standardized diagnostic criteria, integration of neuroimaging and biomarker data and improved diagnostic accuracy for spirochaetal infections.\n\nID: 41770041\nTitle: The lp17 regulatory elements in Borrelia burgdorferi: a novel small RNA impacts gene expression and mammalian infection.\nAbstract: The segmented genome of Borrelia burgdorferi, the tick-borne agent of Lyme disease, encodes numerous chromosomal and plasmid-borne proteins and small RNAs (sRNAs) of unknown function that are critical for infectivity. Two recent examples are the linear plasmid (lp)17-encoded protein BBD18 and sRNA SR0736 (also termed as ittA), which promote spirochete survival in ticks and mammals, respectively. Using targeted mutagenesis of the bbd18 locus, complementation, and phenotypic analysis of isogenic mutants, we herein confirm and extend the regulatory roles of BBD18 and SR0736 (ittA). A mutant lacking BBD18 and SR0736 (ittA) persisted in ticks, yet failed to infect immunocompetent or immunodeficient mice. Although bbd18 complementation selectively restored bbd18 expression, it did not rescue murine infectivity, supporting an essential role for SR0736 (ittA) during mammalian infection. Transcriptomic and proteomic analyses revealed widespread alterations in expression profiles that were only partially rescued by bbd18 complementation, suggesting distinct regulatory functions for BBD18 and SR0736 (ittA). Because an additional sRNA (SR0735) lies immediately downstream relative to bbd18, we generated an isogenic SR0735 inactivation mutant, which was likewise largely noninfectious in mice and exhibited dysregulation of multiple gene products, including the induction of several lp17 genes, such as bbd18, and the downregulation of multiple proteins, such as OspC, BamA, and DbpA. Together, these data indicate that the bbd18 locus is surrounded by two essential sRNA elements, SR0735 and SR0736 (ittA), all three of which independently regulate genes, including ones impacting mammalian infectivity. Further characterization of such atypical regulatory elements in B. burgdorferi may inform new control strategies. Borrelia burgdorferi, the tick-borne agent of Lyme disease, is the causative agent of one of the most prevalent vector-borne infections in many regions worldwide. Despite extensive study, the biological functions of many of its protein and small RNA (sRNA) products remain poorly defined. Here, we confirm and extend the regulatory roles of the linear plasmid (lp)17-encoded protein BBD18 and the sRNA SR0736 (ittA) in spirochete infectivity. Importantly, we identify a previously unrecognized regulatory function for an adjacent sRNA, SR0735, underscoring lp17 as a key regulatory region in B. burgdorferi. Together, our findings highlight the bbd18 locus and its surrounding sRNA elements as an independent, multilayered regulatory module that controls gene products, including those required for mammalian infection. Defining how these three regulators shape gene expression and virulence will reveal new mechanisms underlying Lyme disease pathogenesis and may inform the development of new strategies to prevent this widespread illness.\n\nID: 41707949\nTitle: Probable Lyme carditis in pacemaker candidates with atrioventricular block: Preliminary results from northern Serbia.\nAbstract: This study aimed to estimate the proportion of patients with newly diagnosed cardiac conduction disorders requiring pacemaker implantation who have serological findings consistent with probable Lyme carditis in endemic northern Serbia. Adults presenting with new conduction disorders and scheduled for permanent pacing were enrolled and provided serum at baseline and 4-week follow-up. Anti-Borrelia immunoglobulin (Ig)G was assessed using a two-tier algorithm (enzyme-linked immunosorbent assay screening, immunoblot confirmation). Probable Lyme carditis was defined as IgG seroconversion or stable/rising titers; no Lyme carditis was defined as persistent seronegativity or declining titers. Of 80 enrolled patients, 74 completed follow-up (92.5%; mean age 71.6 years; 68.9% male). Third-degree atrioventricular block was most frequent (56.8%). Probable Lyme carditis was identified in eight of 74 (10.8%) patients. Of 14 patients who were enzyme-linked immunosorbent assay-reactive/borderline, six (42.9%) were immunoblot-negative. Seropositive patients were older (age 76.3 vs 71.1 years); titers were higher in men at 4 weeks. IgG positivity was associated with suspected Lyme carditis (relative risk 6.8 at baseline; 16.2 at 4 weeks). No participant reported a recent tick bite or erythema migrans. Approximately one in 10 pacemaker candidates showed serological patterns compatible with probable Lyme carditis. Incorporating two-tier paired serology into evaluation of high-grade conduction disorders in endemic settings may improve etiologic diagnosis and inform management.\n\nID: 41700859\nTitle: Strain-specific immune response patterns to Borrelia burgdorferi infection: a comparative transcriptomic analysis in C3H and C57BL/6 mice.\nAbstract: Borrelia burgdorferi (Bb), transmitted through tick vectors, induces Lyme arthritis (LA), with disease progression intimately correlated with host genetic characteristics. Laboratory investigations have demonstrated marked disparities in infection responses among distinct mouse strains: C57BL/6 mice have mild arthritis and rapid tissue repair, whereas C3H mice exhibit severe arthritic manifestations. Comparing these strains has helped identify genetic and immune factors important for arthritis development. In this study, female C57BL/6 and C3H mice were inoculated with Bb via bilateral footpad injection. Disease progression was evaluated through multidimensional parameters, including joint swelling measurements, radiographic examinations, and histopathological analyses at acute (14 days) and chronic (56 days) phases. RNA-seq of joint tissue, combined with single-sample gene set enrichment analysis, immune deconvolution, and multi-omics enrichment revealed strain-divergent signatures. The experimental data unveiled strain-specific immune response patterns: C3H mice exhibited persistent inflammatory responses characterized by heightened complement system activation, sustained inflammatory mediator expression, and prolonged inflammasome activity. C57BL/6 mice maintained relatively stable inflammatory mediator levels and immune homeostasis. Transcriptomic analysis revealed 2,183 (C3H) and 439 (C57BL/6) differentially expressed genes on day 14 post-infection, encompassing processes related to immune cell recruitment, cytokine networks, and complement activation. These findings illuminate the regulatory role of host genetic background in temporal characteristics of immune responses, providing novel molecular insights into differential susceptibility to LA.\n\nID: 41563653\nTitle: Borrelia burgdorferi-Induced Neuroinflammation in Lyme Disease: A Potential Driver of Alzheimer's Disease Pathology?\nAbstract: Emerging evidence suggests that chronic infections may contribute to neurodegenerative diseases such as Alzheimer's disease (AD). One such infection is caused by Borrelia burgdorferi sensu lato (Bbsl), the spirochete complex responsible for Lyme disease, which can invade the central nervous system (CNS) and trigger Lyme neuroborreliosis (LNB). Bbsl infection is associated with persistent neuroinflammatory responses and immune evasion mechanisms, which may contribute to long-term neurological sequelae in a subset of patients. Neuroinflammation is increasingly recognized as a contributing factor in AD pathogenesis. This review examines proposed mechanistic overlaps between LNB and AD, focusing on the role of Bbsl-induced neuroinflammation driving amyloid-beta (A\u03b2) accumulation and tau pathology. We summarize evidence from in vitro, in vivo, and postmortem studies reporting assay-dependent co-localization of Borrelia with hallmark AD pathology in selected cases, alongside epidemiological studies that yield mixed results. While some studies suggest an association between Bbsl exposure and neurodegenerative risk, others report no clear correlation. Overall, current evidence indicates only an association, and a causal relationship between Bbsl infection and AD has not been established. Understanding this potential link may inform future mechanistic studies, biomarker development, and preventive strategies targeting chronic infection-driven neuroinflammation to address the hypothesis.\n\nID: 41481600\nTitle: Targeting of interaction between BB0323-BB0238 informs new paradigms in Lyme disease therapeutics.\nAbstract: Borrelia burgdorferi, one of the most prevalent tick-borne pathogens, can cause a complex and multisystem illness called Lyme disease, where there has been an unmet need for novel therapeutic or preventive strategies. We previously identified an essential protein-protein interaction (PPI) event in B. burgdorferi involving two unique proteins, BB0323 and BB0238; herein, we show that this PPI is indispensable for long-term borrelial survival in mammals and explore its potential as a novel target for small molecule therapeutics. Using X-ray crystallography, we solved the structure of the BB0238-BB0323 complex and identified the hotspot residues that form the biomolecular PPI interface area of ~1000 square \u00c5ngstroms. We then performed quantitative high-throughput drug screens of 62,740 diverse small molecules utilizing an amplified luminescent proximity homogeneous assay linked immunosorbent assay (AlphaLISA). Following a comprehensive pipeline to confirm small molecule hits, we short-listed three distinct PPI inhibitors of BB0238-BB0323. One of these inhibitors, called lomibuvir (VX-222, VCH-222), displayed robust PPI inhibition inside B. burgdorferi cells and was shown to affect pathogen persistence in a tick-borne murine model of Lyme disease. Our study highlights targeted PPI disruption as a new therapeutic strategy against B. burgdorferi and may foster future antimicrobial discovery efforts to resolve clinical complications associated with Lyme disease.\n\nID: 41480807\nTitle: The BosR Is Back!\nAbstract: BosR is a novel nucleic acid-binding protein in the ferric uptake regulator (FUR) family that regulates gene expression in the Lyme disease spirochete Borrelia (Borreliella) burgdorferi. This issue of Molecular Microbiology contains a comprehensive transcriptomic study that keenly defines the regulatory swath of BosR in the vertebrate host of B. burgdorferi. Despite homology to Fur-like and PurR-like orthologs, BosR has traditionally been linked to regulation of RpoS, the alternative sigma factor that controls the regulon required for establishing a vertebrate infection. However, BosR regulates other genes through an RpoS-independent mechanism, which is elegantly elaborated in Grassmann et\u00a0al., along with clearly demonstrating that BosR does not participate in the defense against oxidative and nitrosative stress in the vertebrate. However, the recently recognized role of BosR as an RNA-binding protein with RNA chaperone activity that regulates gene expression in a post-transcriptional fashion is not wholly appreciated, which clouds the results on determining the DNA-binding site in\u00a0vivo. Regardless, this seminal study enshrines BosR as a major regulator of gene expression in B. burgdorferi and delineates a multitude of BosR-regulated cellular functions in the spirochete related to its ability to navigate between its tick vector and vertebrate host in nature as well as to persist in these two disparate environments.\n\nID: 41333458\nTitle: Toll-like receptor 1 polymorphism is associated with impaired immune tolerance, dysregulated inflammatory responses to Borrelia burgdorferi, and heightened risk of post-infectious Lyme arthritis.\nAbstract: Clinical presentation of Lyme disease is largely due to host immune response to infection. Previously, we identified a variant (1805GG) in the TLR1 gene, a key immune sensor for Borrelia burgdorferi, which was associated with excessive inflammation and severe disease. Herein we examined the mechanism by which this variant leads to dysregulated immunity. We found that patients with post-infectious Lyme arthritis, a condition characterized by marked persistent synovitis in joints, have a higher frequency of TLR1-1805GG compared to those whose arthritis resolves with antibiotics. To explore the possibility that this genotype-phenotype association was due to excessive inflammation, we then tested the functional impact of TLR1-1805GG on inflammatory responses and immune tolerance in PBMCs with or without this SNP and in THP-1 cell lines lacking TLR1. In response to B. burgdorferi stimulation, PBMCs with TLR1-1805GG had greater transcriptional upregulation of ~1200 immune-related genes and significantly higher cytokine levels in supernatants compared to cells without this variant. Moreover, repeat B. burgdorferi stimulation, which mimics tolerogenic conditions during the infection, failed to induce innate immune tolerance in PBMCs with TLR1-1805GG, or in THP-1 cells lacking TLR1, resulting in seemingly unabated immune activation consistent with marked inflammation in Lyme arthritis joints. These results suggest that excessive inflammation in patients with TLR1-1805GG variant appears to be due to immune dysregulation and inability to induce immune tolerance. The findings help explain how early events during the infection may contribute to sustained immune activation after antibiotics and point to the role of TLR1 signaling in immune regulation.\n\nID: 41319868\nTitle: Guidelines for Lyme borreliosis: clinical manifestations.\nAbstract: Lyme borreliosis (LB) is a tick-borne zoonosis caused by spirochetes belonging to the Borrelia burgdorferi sensu lato (Bb sl) complex. In Europe, multiple pathogenic species-including B. afzelii, B. garinii, and B. burgdorferi sensu stricto-are responsible for a wide diversity of clinical manifestations. The disease may present in various stages-localized, early disseminated, or late disseminated-depending on the time elapsed since the tick bite and the organs involved, such as the skin, joints, or nervous system. Erythema migrans (EM) is the most frequent clinical presentation, accounting for approximately 80\u00a0% of LB cases in France. It is an early localized form, characterized by a painless, centrifugally expanding erythematous lesion centered on the tick-bite site, typically appearing 3 to 30\u00a0days post-exposure and resolving within 15\u00a0days under antibiotic therapy. Neuroborreliosis (NBL), most commonly associated with B. garinii, occurs in approximately 6-15\u00a0% of French cases. It represents a disseminated form, often presenting as meningoradiculitis or peripheral facial palsy, with generally favorable outcomes under antibiotic treatment, although persistent post-infectious symptoms may occur. These guidelines address the full clinical spectrum of LB, from common manifestations such as EM to rare complications involving cardiac or ophthalmological systems. They also encompass atypical presentations not specifically linked to LB and provide specific recommendations for special populations, including pregnant women and immunocompromised patients. The current section summarizes the principal clinical features of LB and supports the rationale underlying recent diagnostic and therapeutic recommendations.\n\nID: 41213278\nTitle: Immunogenicity and safety of an 18-month booster dose of the VLA15 Lyme borreliosis vaccine candidate after primary immunisation in children, adolescents, and adults in the USA: a randomised, observer-blind, placebo-controlled, phase 2 trial.\nAbstract: Lyme borreliosis is the most common tick-borne disease in temperate climates of the northern hemisphere. Although in some cases Lyme borreliosis progresses to serious outcomes, no human vaccines are available for its prevention. A previous report showed positive immunogenicity and safety of VLA15, an investigational Lyme borreliosis vaccine based on Borrelia burgdorferi outer surface protein A (OspA), when administered as a 0-2-6-month or 0-6-month primary series to children, adolescents, and adults. Here, we report data from the same trial after receipt of an initial booster dose at month 18. This ongoing, randomised, observer-blind, placebo-controlled, phase 2 trial is taking place at 14 clinical study centres in Lyme borreliosis-endemic areas in the USA. Healthy, eligible participants aged 5-65 years were enrolled. Participants were randomly assigned within each age cohort (18-65 years, 12-17 years, and 5-11 years) in a 1:1:1 ratio to receive intramuscular injections of VLA15 at months 0, 2, and 6; VLA15 at months 0 and 6 and placebo at month 2; or placebo at months 0, 2, and 6. In this phase of the trial, a month 18 VLA15 booster vaccination was administered to participants in both VLA15 groups (termed VLA15 M0-2-6-18 and VLA15 M0-6-18, respectively); the placebo group received placebo at month 18. Data up to month 12, including the primary endpoints, have been reported previously; this report includes data up to month 19. Secondary endpoints related to the month 18 booster vaccination included OspA serotype-specific IgG geometric mean titres (GMTs; evaluated in the per-protocol analysis set) and solicited and unsolicited adverse events (evaluated in the safety analysis set [ie, all participants who received one or more vaccinations]) from month 18 to month 19. This trial is registered at ClinicalTrials.gov, NCT04801420, and is closed for recruitment. Between March 15, 2021, and Feb, 24, 2022, 625 participants were randomly assigned and received the first vaccination. 532 (85%) of 625 participants were White, 68 (11%) were Black or African American, 13 (2%) were Asian, one (<1%) was an American Indian or Alaska Native, and 11 (2%) had their race recorded as other. 321 (51%) of 625 participants were female and 304 (49%) were male. The month 18 booster vaccination was administered to 449 participants at 13 of the trial sites (148 participants in the VLA15 M0-2-6-18 group; 143 participants in the VLA15 M0-6-18 group; 12 other VLA15 recipients; and 146 participants in the placebo group) between Sept 21, 2022, and Jan 24, 2023. The 12 other VLA15 booster recipients, of whom 11 received VLA15 and one received placebo for the month 18 booster, received at least one primary or booster VLA15 dose but could not be evaluated within a designated VLA15 group for safety because of missed or incorrect vaccinations, and were excluded from post-booster immunogenicity analyses. Of the 513 participants included in the per-protocol analysis set, 398 received the booster and 394 completed the month 19 visit. OspA-specific IgG GMTs in both VLA15 groups declined after the primary series up to month 18. At 1 month after the month 18 booster vaccination, GMTs in both VLA15 groups rose to levels that exceeded those after the primary series, ranging in the overall population from 1057\u00b70 U/mL (95% CI 843\u00b71-1325\u00b71; serotype 1) to 1807\u00b79 U/mL (1486\u00b72-2199\u00b73; serotype 2) in the M0-2-6-18 group and from 830\u00b70 U/mL (621\u00b73-1108\u00b79; serotype 1) to 1603\u00b71 U/mL (1239\u00b77-2073\u00b70; serotype 2) in the M0-6-18 group. GMTs at month 19 were higher in the paediatric cohorts compared with adults, consistent with observations after the primary vaccination series. The tolerability profile of the month 18 booster was similar to that of the primary doses and generally similar across age cohorts. Related unsolicited adverse events were reported by four (1%) of 302 VLA15 booster vaccination recipients and three (2%) of 147 placebo booster recipients within 1 month after the month 18 booster; all of these events resolved without sequelae. Unsolicited adverse events leading to trial withdrawal, unsolicited serious adverse events, and adverse events of special interest that were reported up to month 19 were all considered unrelated to trial vaccination and occurred before the month 18 booster. No deaths were reported up to month 19 of the trial. The safety and robust anamnestic immune responses associated with VLA15 boosting support its use as a strategy to increase anti-OspA antibody levels before tick season among children, adolescents, and adults. Forthcoming data after administration of subsequent annual boosters will provide further information about VLA15 antibody persistence and boostability.

The spirochete acquires cholesterol from the host to form cholesterol glycolipids, which are then incorporated into the spirochete's membrane. This study aimed to determine whether higher levels of serum cholesterol could facilitate the infection and contribute to the pathogenesis of Lyme disease. We investigated the effect of acute and chronic hypercholesterolemia on spirochetal infection in C3H/HeJ mice fed a high-fat diet (HF) compared to mice fed a control diet. The course of infection in mice was followed for 3 weeks (short-term effects) and 16 weeks post-infection (long-term effects) by measuring spirochete bioluminescence in vivo. At the endpoint, bacterial burden was measured in tissues by real-time PCR, and histology was performed to assess differences in the inflammatory response. Between days 10 and 14 post-infection, live imaging showed that mice on a HF diet presented a significantly higher spirochetal burden and greater dissemination than the controls. These differences were transient and restricted to the first two weeks of infection, without long-term effect observed. Histology showed no significant differences in inflammation between HF and control mice. However, qPCR showed that mice fed with HF diet had a higher B. burgdorferi burden in tissues, including heart, visceral, and subcutaneous fat. These findings revealed that high cholesterol levels resulting from a HF diet led to increases in spirochetal burden and dissemination early in the infection, suggesting that cholesterol may contribute to spirochete persistence and associated Lyme disease symptoms.\n\nID: 42321833\nTitle: Gastrointestinal symptoms correlate with core clinical features and systemic inflammation in myalgic encephalomyelitis/chronic fatigue syndrome.\nAbstract: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating multisystem illness marked by fatigue, cognitive impairment, and post-exertional malaise. Gastrointestinal (GI) symptoms are frequently reported, yet their relationship to central features of the illness and biological correlates remains poorly understood. We aimed to characterize GI symptom burden in ME/CFS and evaluate its associations with core clinical features and specific immune and inflammatory markers, with attention to potential gut-related contributions to disease expression. GI symptoms and 49 additional symptoms across nine domains were assessed in 116 ME/CFS patients and 80 matched controls. Plasma C-reactive protein (CRP) and antibodies against dietary and microbial antigens were measured as indicators of systemic inflammation and putative gut-derived antigen exposure. ME/CFS patients reported significantly elevated GI symptom frequency and severity compared with controls, with 53% of ME/CFS patients versus 8% of controls reporting a prior diagnosis of irritable bowel syndrome. GI symptom burden correlated with fatigue, cognitive difficulties, flu-like symptoms, pain, sleep disturbances, neurological complaints, and sensory sensitivities, independent of illness duration. CRP levels were higher in patients with greater GI symptoms and correlated with GI, fatigue, musculoskeletal pain, and flu-like symptom burden. Patients with greater flu-like symptom expression exhibited higher IgM responses to dietary gliadin and bacterial lipopolysaccharide. These associations were not detected in controls. GI symptoms are a prominent, clinically relevant dimension of ME/CFS, associated with broader symptom burden and inflammatory heterogeneity. These findings highlight the relevance of gut-related and immune processes in ME/CFS and underscore the value of incorporating GI symptom assessment in translational studies to help refine mechanistic understanding and improve therapeutic stratification.\n\nID: 41967005\nTitle: Making Invisible Illnesses Visible: Recognizing and Responding to Infection Associated Chronic Conditions.\nAbstract: The emergence of post-COVID conditions (PCC) has renewed attention to infection-associated chronic conditions and illnesses (IACCI), including myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and Lyme disease-associated chronic symptoms. Millions of Americans are affected by these debilitating, misunderstood conditions, which share symptom profiles and pathophysiologic abnormalities. IACCI have received insufficient clinical attention and research investment. We outline elements of a patient-centered approach to care, emphasizing validation of patients' experiences, multidisciplinary management, and symptom-focused treatment. Opportunities to strengthen clinical practice include a new CMS code for chronic condition management, extended visits, and creation of welcoming care environments. Advances in PCC and ME/CFS research provide a foundation for exploring shared mechanisms and developing targeted therapies. Improved surveillance, harmonized research, and inclusive trial designs are needed to define disease burden and accelerate therapeutic progress. Coordinated action by clinicians, researchers, and policymakers can help address longstanding gaps and improve outcomes for all individuals with IACCI.\n\nID: 41888159\nTitle: Lyme borreliosis.\nAbstract: Lyme borreliosis is the most common tick-borne disease in the northern hemisphere. It is a zoonosis caused by several species of Borrelia burgdorferi sensu lato and transmitted by the bite of infected ticks of the Ixodes ricinus complex. Lyme borreliosis in North America and Europe differs in certain respects, likely reflecting the different Borrelia species that cause human disease in these locations. The earliest manifestation of Lyme borreliosis is the skin lesion erythema migrans, which develops at the tick\u00a0bite site, typically 7-14 days after the bite. Some untreated patients will then (within the first few weeks or months after onset of the infection) develop additional erythema migrans skin lesions or other clinical manifestations such as borrelial lymphocytoma, nervous system involvement or carditis. Several months or even years after infection onset, Lyme arthritis or acrodermatitis chronica atrophicans may develop. The diagnosis of typical erythema migrans is clinical, whereas for all other manifestations\u00a0the diagnosis is supported via serological testing. Treatment with an appropriate antibiotic will result in resolution of clinical symptoms in most patients; however, some patients experience prolonged subjective symptoms, which usually improve over time. Repeated courses of antimicrobials are not beneficial except in rare cases when there is objective evidence of treatment failure.\n\nID: 41441042\nTitle: Metabolomics-Based Machine Learning Diagnostics of Post-Acute Sequelae of SARS-CoV-2 Infection.\nAbstract: Background: COVID-19 has taken millions of lives and continues to affect people worldwide. Post-Acute Sequelae of SARS-CoV-2 Infection (also known as Post-Acute Sequelae of COVID-19 (PASC) or more commonly, Long COVID) occurs in the aftermath of COVID-19 and is poorly understood despite its widespread effects. Methods: We created a machine-learning model that distinguishes PASC from PASC-similar diseases. The model was trained to recognize PASC-dysregulated metabolites (p \u2264 0.05) using molecular descriptors. Results: Our multi-layer perceptron model accurately recognizes PASC-dysregulated metabolites in the independent testing set, with an AUC-ROC of 0.8991, and differentiates PASC from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, postural orthostatic tachycardia syndrome (POTS), and irritable bowel syndrome (IBS). However, it was unable to differentiate fibromyalgia (FM) from PASC. Conclusions: By creating and testing models pairwise on each of these diseases, we elucidated the unique strength of the similarity between FM and PASC relative to other PASC-similar diseases. Our approach is unique to PASC diagnosis, and our use of molecular descriptors enables our model to work with any metabolite where molecular descriptors can be identified, as these descriptors can be generated and compared for any metabolite. Our study presents a novel approach to PASC diagnosis that partially circumvents the lengthy process of exclusion, potentially facilitating faster interventions and improved patient outcomes.\n\nID: 41350176\nTitle: The lingering shadow of epidemics: post-acute sequelae across history.\nAbstract: The SARS-CoV-2 pandemic has drawn global attention to post-acute infection syndromes (PAIS), with millions affected by post-acute sequelae of COVID-19 (PASC, or Long COVID). While Long COVID is newly defined, PAIS have been described for over a century following epidemic infections. Multiple pathogens - including influenza, Epstein-Barr virus, and Borrelia burgdorferi, among others - can precipitate persistent, poorly understood symptoms. Chronic illnesses such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) have long been linked to infectious triggers. This recurring association highlights critical knowledge gaps and underscores the need for systematic investigation. Unlike prior pandemics, the current era offers advanced technologies and analytic tools to address these gaps. Defining the biology of Long COVID may yield broader insights into host-pathogen interactions and mechanisms of chronic illness.\n\n\n\nID: 40485158\nTitle: Long COVID as an Infection-Associated Chronic Condition: Implications.\nAbstract: A link between infection and chronic illness has been recognized, along with the complexities of interactions between pathogen, environment, host genetics, route of exposure, and timing of outcomes. The COVID-19 pandemic has brought this issue to the forefront and Long COVID is recognized to be an infection associated chronic condition. However, given the wide range of Long COVID presentations, the singular expression gives a false sense of simplicity. Long COVID is best considered as a group of infection associated conditions requiring developing research studies and treatment trials that address the inherent heterogeneity.\n\nID: 40330647\nTitle: Case Report: The intersection of psychiatry and medicine: diagnostic and ethical insights from case studies.\nAbstract: The intersection of psychiatry and medicine presents unique diagnostic and ethical challenges, particularly for conditions involving significant brain-body interactions, such as psychosomatic, somatopsychic, and complex systemic disorders. This article explores the historical and contemporary issues in diagnosing such conditions, emphasizing the fragmentation of medical and psychiatric knowledge, biases in clinical guidelines, and the mismanagement of complex illnesses. Diagnostic errors often arise from insufficient integration between general medicine and psychiatry, compounded by the reliance on population-based guidelines that neglect individual patient needs. Misclassification of conditions like myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, and fibromyalgia as psychosomatic or psychogenic has led to stigmatization and delayed care. While these conditions are referenced as emblematic examples of misclassified and poorly understood disorders, the five clinical cases discussed in this article do not directly illustrate these diseases. Instead, they exemplify shared diagnostic and ethical dilemmas at the medicine-psychiatry interface, including uncertainty, fragmentation, and the risk of epistemic injustice. The article critically examines terms like medically unexplained symptoms and functional disorders, highlighting their limitations and potential for misuse. Case examples underscore the consequences of diagnostic inaccuracies and the urgent need for improved approaches. Ethical considerations are also explored, emphasizing respecting patient experiences, promoting individualized care, and acknowledging the inherent uncertainties in medical diagnosis. Advances in technologies such as brain imaging and molecular diagnostics offer hope for bridging the gap between psychiatry and medicine, enabling more accurate assessments and better patient outcomes. The article concludes by advocating comprehensive training at the medicine-psychiatry interface and a patient-centered approach that integrates clinical observation, research insights, and a nuanced understanding of mind-body dynamics.\n\nID: 39994562\nTitle: A comparison of genome-wide association analyses of persistent symptoms after Lyme disease, fibromyalgia, and myalgic encephalomyelitis - chronic fatigue syndrome.\nAbstract: Up to 20% of Lyme disease cases experience post-treatment Lyme disease syndrome (PTLDS). The biological basis for PTLDS is poorly understood and no evidence-based treatment has been identified. Genetic studies have the potential to elucidate PTLDS pathophysiology and identify treatment targets. We used electronic health record data (EHR) and genetic data from a linked biorepository to conduct a genome-wide association study (GWAS) for PTLDS among patients from a Pennsylvania health system. We evaluated the validity of the GWAS results in two separate conditions that have hypothesized overlapping pathophysiology, fibromyalgia and myalgic encephalomyelitis - chronic fatigue syndrome (ME/CFS). GWAS analyses were performed using logistic regression in SUGEN, assuming an additive genetic model, and adjusting for age, sex, array, and the first 10 principal components calculated from whole genome genotyping to adjust for ancestry, and accounting for relatedness including all 1st degree relationships. The functional mapping and annotation analysis (FUMA) tool was used to explore top findings from our GWAS. Among the 161,875 eligible MyCode participants with genotyping, there were 3,585 who met the criteria for treated Lyme disease. A subset of 695 (19.4%) of these patients met the criteria for PTLDS and the remaining 2890 were classified as controls. We identified two PTLDS loci that reached the suggestive significance threshold (P\u2009<\u20095\u2009\u00d7\u200910-\u20097), with lead variants rs77857587, near IRX1, and rs10833979, near GAS2. Our top index single nucleotide polymorphism (SNP), rs77857587, is in high linkage disequilibrium with a long-range protein quantitative locus SNP, rs111774530, for the MARC2 (Mitochondrial Amidoxime Reducing Component 2) protein. We identified 5,041 cases of fibromyalgia (150,599 controls) and 2,268 cases of ME/CFS (151,594 controls) among the MyCode participants. Neither of the two suggestively significant loci were associated with fibromyalgia or ME/CFS. We identified two PTLDS loci that reached a suggestive significance threshold. Our top index SNP is associated with the MARC2 protein, a protein that has been linked to multiple immune checkpoints. Further study is needed in a larger population to evaluate whether there is genetic evidence of the role of immune response in the occurrence of PTLDS.\n\nID: 39770289\nTitle: Examining Infant and Child Neurodevelopmental Outcomes After Lyme Disease During Pregnancy.\nAbstract: Lyme disease is the most common vector-borne disease in the United States. Recent environmental and socioecological changes have led to an increased incidence of Lyme and other tick-borne diseases, which enhances the urgency of identifying and mitigating adverse outcomes of Lyme disease exposure. Lyme disease during pregnancy, especially when untreated, may lead to adverse pregnancy and neonatal outcomes; however, long-term child outcomes following utero exposure to Lyme disease have not yet been systematically assessed. This concise review describes the current state of knowledge of Lyme disease as a congenital infection and the potential effects of in utero exposure to Lyme disease infection on the neurodevelopment of infants and children. We highlight the importance of distinguishing between acute Lyme disease and a chronic condition termed Post-Treatment Lyme Disease Syndrome, as the impacts of both conditions on the developing fetus and subsequent child development may differ. The importance of placental pathology for patients with acute or chronic symptoms of Lyme disease in pregnancy is explored. Future research aiming to understand and protect neurodevelopment after antenatal Lyme disease must carefully collect potentially confounding variables such as symptomatology and treatment, use clear and standard case definitions, and follow children into school-age and beyond.\n\nID: 39635815\nTitle: [Long COVID - neurological or somatoform disease?].\nAbstract: Post-COVID condition (also known as long COVID) is a syndrome characterized by persistent symptoms following a suspected or confirmed SARS-CoV-2 infection, lasting for at least two months and are not attributable to other conditions. The most common symptoms include fatigue, diffuse pain, post-exertional malaise and \u201cbrain fog\u201d (impairment of memory and concentration). The pathomechanism of long COVID is the subject of ongoing, intensive research. Our purpose was to review the literature on the pathomechanism of long COVID. We reviewed original and review articles in Hungarian and English on the pathomechanism of long COVID, published between January 2019 and June 2024, in the PubMed and Google Scholar databases. Potential underlying causes of the symptoms are outlined in three main theories. 1) The concept of \u201clong COVID as a distinct neurological disease\u201d suggests that direct viral neuroinvasion, apoptosis, and demyelination processes are responsible for the symptoms. 2) The theory of \u201clong COVID as a systemic disease with neurological symptoms\u201d is based on the virus induced, prolonged cytokine and chemokine release, as well as the reactivation of latent viral infections. 3) According to the concept of \u201clong COVID as a somatoform disorder\u201d, the disease results from abnormal activation of the proinflammatory cytokine network leading to central nervous system sensitization, a well-known psychoneuroimmunological mechanism. Our study highlighted significant overlaps between long COVID and conditions such as chronic fatigue syndrome/myalgic encephalomyelitis, a group of symptoms not defined as a distinct mental disorder in DSM-5, but commonly referred to as Gulf War syndrome, chronic Lyme disease and somatic symptom disorder. The pathomechanism of long COVID, which presents with a wide range of nonspecific symptoms, remains unknown, and no reproducible disease-specific biomarker has been identified to date. Clarifying the etiology of the disease is crucial for determining adequate and effective therapeutic methods.

In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients. The most frequent neurological syndromes were radiculoneuritis (36.84%), bilateral facial palsy (13.56%), radiculoneuritis and bilateral facial palsy (10.52%) and multiple cranial mononeuropathy (10.52%), among others. 78.9% achieved a complete recovery, and 15.79% developed post-treatment Lyme disease syndrome. Despite the high incidence of Lyme disease in Asturias, the cases based on hospital admission that can be classified as active disease are lower than those published based on hospital coding. The main source of diagnostic error is positive serological results, without other clinical context, especially in patients studied for cognitive impairment or encephalopathy.\n\nID: 39529800\nTitle: A sex-based analysis of complete blood count features during acute, untreated Lyme disease.\nAbstract: Although lymphopenia has been described in acute Lyme disease (LD), the complete blood count (CBC) has not been comprehensively examined, nor have sex-based analyses been conducted. We analyzed CBC values and identified sex-based trends among patients with early LD by comparing both to controls without a history of LD and to patients' pre-morbid values. We enrolled participants from the Mid-Atlantic US with diagnostic erythema migrans and controls with no history of LD. CBC results were obtained, and patient information was recorded using standardized instruments. We also calculated a neutrophil-to-lymphocyte ratio (NLR). We used linear regression to test that CBC results would differ (a) between antibiotic-naive patients with early LD and controls and (b) by measures of acute disease severity. We also performed stratified analyses to assess sex-based differences. In total, 236 antibiotic-naive patients with early LD had significantly lower lymphocytes (\u03b2\u2009=\u2009-0.34, p\u2009<\u20090.001) and significantly higher monocytes (\u03b2\u2009=\u20090.09, p\u2009=\u20090.002) and NLRs (\u03b2\u2009=\u20090.99, p\u2009<\u20090.001) than 61 controls in adjusted analyses. Lymphocytes, monocytes, and NLRs also changed significantly from pre-morbid to acute LD (p\u2009<\u20090.001 for all). Only the NLR was consistently significantly associated with disease severity. A higher proportion of male patients with early LD had acute lymphopenia than female patients with early LD (31.93% vs. 19.66%, p\u2009=\u20090.03); this difference was not present among controls. The presence of lymphopenia and the absence of an elevated total white blood cell count make LD an important diagnostic consideration in patients presenting with undiagnosed infectious syndromes in endemic regions. This may be especially true for male patients.\n\nID: 39345262\nTitle: Current and emerging approaches for eliminating Borrelia burgdorferi and alleviating persistent Lyme disease symptoms.\nAbstract: Lyme disease is the most prevalent tick-borne infection caused by Borrelia burgdorferi bacteria in North America. Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated \u223c10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection.\n\nID: 39338918\nTitle: PCR Detection of Bartonella spp. and Borreliella spp. DNA in Dry Blood Spot Samples from Human Patients.\nAbstract: Lyme disease is the most commonly reported vector-borne disease in the United States. Bartonella constitute an additional zoonotic pathogen whose public health impact and diversity continue to emerge. Rapid, sensitive, and specific detection of these and other vector-borne pathogens remains challenging, especially for patients with persistent infections. This report describes an approach for DNA extraction and PCR testing for the detection of Bartonella spp. and Borreliella spp. from dry blood spot (DBS) specimens from human patients. The present study included extraction of DNA and PCR testing of DBS samples from 105 patients with poorly defined, chronic symptoms labeled as Lyme-Like Syndromic Illness (LLSI). Bartonella spp. DNA was detected in 20/105 (19%) and Borreliella spp. DNA was detected in 41/105 (39%) patients with LLSI. Neither group of organisms was detected in DBS samples from 42 healthy control subjects. Bartonella spp. 16S-23S rRNA internal transcribed spacer sequences were highly similar to ones previously identified in yellow flies, lone star ticks, a human patient from Florida, mosquitoes in Europe, or B. apihabitans and choladocola strains from honeybees. These human strains may represent new genetic strains or groups of human pathogenic species of Bartonella. The 41 Borreliella spp. flaB gene sequences obtained from human patients suggested the presence of four different species, including B. burgdorferi, B. americana, B. andersonii, and B. bissettiae/carolinensis-like strains. These results suggest that specific aspects of the DBS DNA extraction and PCR approach enabled the detection of Bartonella spp. and Borreliella spp. DNA from very small amounts of human whole blood from some patients, including specimens stored on filter paper for 17 years.\n\nID: 39199993\nTitle: Biomarker-Based Analysis of Pain in Patients with Tick-Borne Infections before and after Antibiotic Treatment.\nAbstract: Tick-borne illnesses (TBIs), especially those caused by Borrelia, are increasingly prevalent worldwide. These diseases progress through stages of initial localization, early spread, and late dissemination. The final stage often leads to post-treatment Lyme disease syndrome (PTLDS) or chronic Lyme disease (CLD), characterized by persistent and non-specific multisystem symptoms affecting multiple systems, lasting over six months after antibiotic therapy. PTLDS significantly reduces functional ability, with 82-96% of patients experiencing pain, including arthritis, arthralgia, and myalgia. Inflammatory markers like CRP and TNF-alpha indicate ongoing inflammation, but the link between chronic pain and other biomarkers is underexplored. This study examined the relationship between pain and biomarkers in TBI patients from an Irish hospital and their response to antibiotic treatment. Pain ratings significantly decreased after antibiotic treatment, with median pain scores dropping from 7 to 5 (U = 27215.50, p < 0.001). This suggests a persistent infection responsive to antibiotics. Age and gender did not influence pain ratings before and after treatment. The study found correlations between pain ratings and biomarkers such as transferrin, CD4%, platelets, and neutrophils. However, variations in these biomarkers did not significantly predict pain changes when considering biomarkers outside the study. These findings imply that included biomarkers do not directly predict pain changes, possibly indicating allostatic load in symptom variability among long-term TBI patients. The study emphasizes the need for appropriate antibiotic treatment for TBIs, highlighting human rights issues related to withholding pain relief.\n\nID: 39187577\nTitle: Long COVID diagnostic with differentiation from chronic lyme disease using machine learning and cytokine hubs.\nAbstract: The absence of a long COVID (LC) or post-acute sequelae of COVID-19 (PASC) diagnostic has profound implications for research and potential therapeutics given the lack of specificity with symptom-based identification of LC and the overlap of symptoms with other chronic inflammatory conditions. Here, we report a machine-learning approach to LC/PASC diagnosis on 347 individuals using cytokine hubs that are also capable of differentiating LC from chronic lyme disease (CLD). We derived decision tree, random forest, and gradient-boosting machine (GBM) classifiers and compared their diagnostic capabilities on a dataset partitioned into training (178 individuals) and evaluation (45 individuals) sets. The GBM model generated 89% sensitivity and 96% specificity for LC with no evidence of overfitting. We tested the GBM on an additional random dataset (106 LC/PASC and 18 Lyme), resulting in high sensitivity (97%) and specificity (90%) for LC. We constructed a Lyme Index confirmatory algorithm to discriminate LC and CLD.\n\nID: 39161484\nTitle: What Makes It Tick: Exploring the Mechanisms of Post-treatment Lyme Disease Syndrome.\nAbstract: Post-treatment Lyme disease syndrome (PTLDS), which may also be referred to incorrectly as \"chronic Lyme disease,\" is defined by the Infectious Diseases Society of America (IDSA) as the presence of fatigue, pain, and/or cognitive complaints with the functional impact that persists for more than six months after completing treatment for Lyme disease (LD). These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues.\n\nID: 39058143\nTitle: Widespread Myalgia and Chronic Fatigue: Phagocytes from Macrophagic Myofasciitis Patients Exposed to Aluminum Oxyhydroxide-Adjuvanted Vaccine Exhibit Specific Inflammatory, Autophagic, and Mitochondrial Responses.\nAbstract: (1) Background: Macrophagic myofasciitis (MMF) is an inflammatory histopathological lesion demonstrating long-term biopersistence of vaccine-derived aluminum adjuvants within muscular phagocytic cells. Affected patients suffer from widespread myalgia and severe fatigue consistent with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a poorly understood disorder suspected to result from chronic immune stimulation by infectious and inorganic particles. (2) Methods: In this study we determined the immuno-metabolic properties of MMF phagocytic cells compared to controls, at rest and upon exposure to aluminum oxyhydroxide adjuvant, with or without adsorbed antigens, using protein quantification and an oxygen consumption assay. (3) Results: MMF and control cells similarly internalized the adjuvant and vaccine but MMF cells specifically expressed Rubicon and Nox2, two molecules unique to the LC3-associated phagocytosis (LAP) machinery, a non-canonical autophagic pathway able to downregulate canonical autophagy. MMF cells exhibited an altered inflammatory secretome, producing more pain-inducing CXC chemokines and less TNF-\u03b1 than controls, consistent with chronic myalgia and exhaustion of the immune system previously documented in ME/CFS. MMF cells exhibited mitochondrial metabolism dysfunction, with exacerbated reaction to adjuvanted vaccine, contrasting with limited spare respiratory capacity and marked proton leak weakening energy production. (4) Conclusions: MMF phagocytes seemingly use LAP to handle aluminum oxyhydroxide vaccine particles, secrete pain-inducing molecules, and exhibit exacerbated metabolic reaction to the vaccine with limited capacity to respond to ongoing energetic requests.\n\nID: 42418108\nTitle: Low work ability and high disability burden in Cushing's syndrome: a multicenter cohort study.\nAbstract: The socio-occupational burden of Cushing's syndrome (CS) remains underrecognised. In clinical practice, surgically treated patients are often considered recovered, potentially overlooking persistent impairment. To evaluate work ability, social and employment status in newly diagnosed and remitted CS. National observational study with two arms: a monocentric prospective study of patients evaluated for suspected endogenous glucocorticoid excess (cohort 1), and a multicenter cross-sectional study of patients in remission from CS, comparing those with recovered versus persistent adrenal insufficiency (cohort 2). All participants underwent standardised assessments and completed validated questionnaires on socioeconomic status, work ability, and fatigue. In cohort 1, individuals with active CS (n\u2009=\u200928) and excluded CS (n\u2009=\u200956) had comparable comorbidities, education, and employment. However, work ability scores were lower in active CS (median 22.5 vs. 28.5, p\u2009=\u20090.008) and correlated inversely with biochemical cortisol excess. In multivariable analyses, active CS and depression were independently associated with lower work ability, whereas older age and depression were independently associated with fatigue severity. In cohort 2 (n\u2009=\u200989, 39 with recovered, 50 with persistent adrenal insufficiency), overall employment was 69%. Poor work ability was common (42% with recovered vs. 58% with persistent adrenal insufficiency) and weekly working hours were lower in those with persistent insufficiency (33\u00a0h vs. 39\u00a0h, p\u2009=\u20090.051). Overall, illness-related absences occurred in 76% during the preceding year, disability was recognised in 47%, and 15% received reduced earning capacity pensions. Fatigue correlated negatively with work ability (r = - 0.73, p\u2009<\u20090.0001). There is an unmet need for structured rehabilitation and reintegration in CS.\n\nID: 42418093\nTitle: Comparative analysis of fatigue and mental health in sexual and gender minority cancer survivors.\nAbstract: This study aims to compare self-reported fatigue and mental health in sexual and gender minority (SGM) cancer survivors and cisgender-heterosexual cancer survivors. Using data from the National Institutes of Health's All of Us Research Program, survey responses from 36,684 respondents with a history of cancer were analyzed. Information collected from respondents included sexual orientation, gender, race, ethnicity, age at first cancer, history of anxiety or depression, and history of fatigue-related diagnoses. Outcomes included surveys assessing fatigue and mental health. SGM individuals were compared with majority groups using multivariable logistic regression. SGM survivors represented 6.6% of the sample. SGM survivors had increased odds of high fatigue than cisgender-heterosexual survivors (OR\u2009=\u20091.33, 95% CI[1.17, 1.51], p\u2009<\u2009.001). SGM survivors also experienced higher odds of self-reported poor mental health when compared with cisgender-heterosexual survivors (OR\u2009=\u20091.85, 95% CI [1.64, 2.03], p\u2009<\u2009.001). After controlling for anxiety, depression, and fatigue, SGM cancer survivors had higher odds of self-rated poor or fair mental health compared to cisgender-heterosexual cancer survivors. Fatigue and mental health are worse among SGM cancer survivors compared to cisgender-heterosexual survivors. Future interventional studies are needed to mitigate the unique fatigue and mental health needs of this population. Given the higher burden of fatigue among SGM cancer survivors, cancer care providers should screen for and address fatigue and mental health needs of SGM individuals impacted by cancer before, during, and after treatment to minimize the impact on their daily life. Outcomes for SGM survivors could be improved by routine sexual orientation and gender identity data collection in oncology settings and cancer databases, by education for SGM-serving primary care clinicians outside of cancer care settings on the care needs of survivors, and by piloting SGM-tailored interventions to address fatigue.\n\nID: 42417827\nTitle: Ergonomic impact of a passive upper-limb exoskeleton on surgeon workload during laparoscopic tasks: a crossover experimental study.\nAbstract: Minimally invasive surgery, particularly laparoscopic surgery, places considerable musculoskeletal strain on surgeons and is associated with high rates of pain, fatigue, numbness, and stiffness. Wearable assistive devices such as exoskeletons have been proposed as ergonomic solutions; however, evidence supporting their effectiveness in laparoscopic surgery remains limited. This study evaluated the feasibility and ergonomic impact of a passive upper-limb exoskeleton during laparoscopic procedures. This prospective crossover study used 28\u00a0porcine models. Twenty surgeons with varying laparoscopic experience each performed two laparoscopic intracorporeal gastrointestinal anastomoses, with and without a passive upper-limb exoskeleton. Surgeons were randomly assigned to begin either with the exoskeleton or without it. The primary outcome was total workload assessed using the NASA Task Load Index\u00a0(NASA-TLX), calculated as the mean of the six domains. Secondary outcomes included individual NASA-TLX domain scores and anastomosis time. Subgroup analyses were also performed according to laparoscopic experience (beginner, intermediate, expert) and anastomosis type (stapled vs. handsewn). No significant difference was observed between the exoskeleton and non-exoskeleton conditions for the primary outcome, the mean total NASA-TLX score. Among the secondary outcomes, the NASA-TLX domains Physical Demand and Effort were significantly lower with the exoskeleton than without it (72.5 [48.8-81.3] vs. 45.0 [25.0-67.5], p\u2009=\u20090.026; 65.0 [40.0-76.3] vs. 37.5 [30.0-70.0], p\u2009=\u20090.025). No significant differences were observed in the other NASA-TLX domains or in anastomosis time. In subgroup analyses, workload was significantly lower with the exoskeleton among expert surgeons (p\u2009=\u20090.036) and during hand-sewn anastomosis (p\u2009=\u20090.009). The exoskeleton did not significantly reduce overall workload. However, it decreased the NASA-TLX domains Physical Demand and Effort during laparoscopic procedures without compromising procedural performance. The reduction in workload appeared more pronounced among expert surgeons and during hand-sewn anastomosis.\n\nID: 42417226\nTitle: Multimodal health monitoring and theranostics based on functionalized hydrogels and artificial intelligence.\nAbstract: Functionalized hydrogels are ideal flexible interfaces for multimodal health monitoring and integrated diagnosis-therapy systems, owing to their tissue-like mechanical properties, programmable biochemical functions, and hierarchical pores. However, practical applications are often limited by several material bottlenecks: mechanical fatigue and conductivity loss under cyclic stress, the mismatch between degradation rate and functional lifespan, and the trade-off between sensitivity and biocompatibility. To address these challenges, artificial intelligence (AI) has been applied to accelerate structural optimization and property prediction through molecular network engineering and inverse design. Meanwhile, during the collection of coupled mechanical and biochemical signals, these interfaces usually suffer from high background noise, data variability, and baseline drift. Machine learning and deep learning can process these complex datasets through noise filtering, automated feature extraction, and pattern recognition, enabling continuous monitoring and adaptive health management. This review summarizes the recent material design strategies of functionalized hydrogels, AI-driven data analysis methods, and their progress and challenges in integrated diagnosis and therapy.\n\nID: 42416941\nTitle: Lost in Translation: Barriers in Psychiatric Care for Patients With Communication Impairments.\nAbstract: Effective communication is central to psychiatric evaluation and treatment. Patients with acquired communication impairments, such as post-stroke aphasia, are at increased risk for misdiagnosis, delayed care, and suboptimal treatment. We aim to better understand the unique needs of psychiatric patients with communication difficulties, common pitfalls in their care, and ways to improve clinical assessment, diagnosis, and treatment of their mental health conditions. We present the case of a 49-year-old woman with a history of major depressive disorder, generalized anxiety disorder, post-traumatic stress disorder, functional neurological symptom disorder, and a left middle cerebral artery ischemic stroke resulting in non-fluent aphasia. She was admitted to an inpatient psychiatric unit for suicidal ideation in the context of significant post-stroke functional decline. Her hospitalization was complicated by limited verbal communication and reliance on nonverbal modalities, cognitive fatigue related to communicating, persistent depression symptoms, as well as fluctuating reports of perceptual disturbances. Communication barriers significantly impacted assessment of mood, suicidality, and perceptual symptoms, contributing to diagnostic uncertainty and complex medical decision-making. This case highlights how expressive aphasia can obscure psychiatric assessment, increase reliance on interpretation by clinicians and caregivers, and contribute to potential misunderstanding of symptoms. It also underscores the importance of multimodal communication strategies and interdisciplinary collaboration. Psychiatric patients with communication impairments require tailored assessment approaches to reduce diagnostic error, gain greater understanding of the patient's clinical presentation, and improve overall patient care. Increased awareness and structured communication strategies may mitigate disparities in this vulnerable population.\n\nID: 42416910\nTitle: Patient perceptions of barriers and facilitators for self-care in surgical fast-track programmes related to capability, opportunity and motivation: a theory-based qualitative study in Sweden.\nAbstract: Surgical care increasingly shifts pre- and postoperative care responsibility to patient self-care at home. By using the capability, opportunity, motivation-behaviour (COM-B) framework, patient determinants influencing self-care can be explained. The aim was to describe patients' experienced facilitators of and barriers to self-care in surgical fast-track programmes related to capability, opportunity and motivation. A qualitative design study with semi-structured interviews was conducted among 27 general and orthopaedic surgery patients at three Swedish hospitals. Data were analysed deductively using the COM-B framework. The patients' self-care experiences were explained by capability, opportunity and motivation and the dynamic interaction between these factors. A key analytical finding was the pivotal role of family and friends, whose emotional and practical support strengthened patients' capability and motivation. Facilitators for behaviour change included prior surgical experience, clear information, physical ability, social and professional support, optimism and realistic goals. Barriers included cognitive and physical limitations, pain, fatigue and emotional distress. Findings highlight family involvement as an underused resource and support policy development of person centred pre- and postoperative self-care strategies. This study advances nursing theory by applying the COM-B model to illuminate interdependent behavioural processes in surgical self-care; themes could occasionally overlap.\n\nID: 42416558\nTitle: Confidence-driven adaptive time window for real-time driver fatigue detection in Level 2-3 autonomous vehicles: a multi-dataset validation study.\nAbstract: Driver fatigue constitutes a critical safety hazard in Level 2-3 (L2-3) conditionally automated vehicles, where the paradoxical demand for sustained supervisory vigilance despite minimal active engagement accelerates cognitive underload and impairs timely takeover readiness. Existing vision-based driver monitoring systems are constrained by fixed temporal analysis windows and binary classifiers that neither quantify prediction uncertainty nor adapt to the heterogeneity of real-world fatigue dynamics, resulting in elevated false alarm rates and poor cross-domain generalization. This study introduces a confidence-driven adaptive time window (CDATW) framework: a closed-loop neuro-computational pipeline that couples a lightweight MobileNetV3-CBAM-BiLSTM spatial-temporal encoder with a Monte Carlo Dropout uncertainty estimator to produce simultaneous fatigue probability and epistemic confidence outputs at each inference step. The confidence signal governs a window controller that contracts observation periods to 5-10\u202fs under high certainty (confidence >0.85) for rapid warning, and extends them to 20-30\u202fs under low certainty (confidence <0.60) to suppress spurious alarms-instantiating the feedback-driven adaptive sensing principle central to neurorobotic perception. The framework was validated on four heterogeneous public datasets (NTHU-DDD, YawDD, UTA-RLDD, and DROZY) under single-dataset, cross-dataset transfer, and mixed-dataset training protocols. Single-dataset accuracy ranged from 88.6 to 91.8% with AUC of 0.92-0.95, while the adaptive mechanism reduced false alarm rates by 35.2% relative to fixed 15-s baselines. The architecture sustains 38-45 FPS on an NVIDIA Jetson Xavier NX automotive embedded platform, and confidence calibration achieves an Expected Calibration Error of 0.078, with high-confidence predictions (>0.9) attaining 95.6% accuracy. These results demonstrate that uncertainty-aware adaptive temporal reasoning embedded in a deployable neurorobotic architecture constitutes a computationally efficient and practically viable strategy for driver state monitoring in L2-3 autonomous vehicles, with broader implications for closed-loop perception in safety-critical human-machine systems.\n\nID: 42416515\nTitle: Advances and Future Expectations in Oncolytic Virus Therapy for Glioblastoma: A Systematic Review of Clinical Trials.\nAbstract: Glioblastoma (GB), or grade IV astrocytoma, is the most prevalent primary tumor of the central nervous system (CNS). This systematic review aimed to investigate the efficacy and tolerability of virotherapy treatment for recurrent and progressive glioblastoma patients. We also examined recent progress in preclinical and clinical trials, and future perspectives. We developed a search strategy using Medical Subject Headings (MeSH) terms and keywords. Inclusion criteria were English language published and ongoing clinical trials that involved patients undergoing virotherapy for glioblastoma. We searched through PubMed, Embase, Ovid, Scopus, Cochrane databases and https://Clinicaltrials.gov from inception until May 9th, 2025. Two independent reviewers screened records, extracted data, and assessed risk of bias (ROB2). No meta-analysis was performed due to heterogeneity. PROSPERO CRD420250636791. Of 975 records screened, 43 studies (24 published, 19 ongoing) enrolled 462 virotherapy patients. Most common adverse events: headache (n=145), fatigue (n=83) and fever (n=78). Risk of bias was moderate to serious in most studies. We encountered several limitations, including high heterogeneity, reporting inconsistencies, and small sample sizes. Most patients experienced disease stabilization. However, objective response and complete remission occurred infrequently. A small proportion of patients achieved long-term survival, suggesting that virotherapy could be effective in specific subgroups. While oncolytic virus therapy is generally tolerated, neurotoxicity remains the most significant risk. Adverse effects were mostly Grade 1-2. Some trials (notably with HSV-1 or NDV) had severe events. Symptoms were often transient and manageable but need closely monitoring. However, the observed heterogeneity, limited data standardisation, and lack of randomized controlled trials, besides tumor heterogeneity, antiviral immunity and immunosuppressive microenvironment, necessitate further research to identify predictive biomarkers and optimize therapeutic protocols. We also suggest further trials on novel delivery methods, such as the nanoparticles, to enhance blood-brain barrier (BBB) penetration.\n\nID: 42416417\nTitle: Hairy cell leukemia in a 51-year-old Syrian male: a case report.\nAbstract: Hairy cell leukemia (HCL), a rare B-cell lymphoproliferative disorder, originates from the splenic marginal zone B cell. However, diagnosis can be particularly challenging in resource-limited settings where advanced tests are not readily available. Misclassification may result in non-selective chemotherapy exposure and increased toxicity. Reporting such cases is important to highlight diagnostic challenges in resource-limited countries. A 51-year-old male presented with abdominal discomfort, weight loss, and fatigue. Examination revealed splenomegaly. Initial evaluation suggested lymphoplasmacytic lymphoma, and the patient received multi-agent chemotherapy (R-CHOP), which was complicated by severe cytopenias. Splenectomy was performed, yielding a spleen weighing 2216\u00a0g. Histopathology and immunophenotyping confirmed hairy cell leukemia. Molecular testing for BRAF V600E (the gold standard for diagnosis) was unavailable due to financial and infrastructural restrictions. Treatment was switched to single-agent cladribine, resulting in marked clinical improvement and a significant reduction in chemotherapy adverse effects. Follow-up imaging and blood work revealed that the patient was in complete remission. In our case, we emphasize the diagnostic challenges of HCL in low-resource environments and clarify how the empirical administration of R-CHOP chemotherapy led to unnecessary toxicity and suboptimal outcomes. Splenectomy played a crucial diagnostic role when bone marrow tests were directional but not conclusive. We provide an extensive review of differential diagnoses, immunophenotypic hallmarks, what lies beyond the BRAF V600E mutation, and therapeutic approaches. Early recognition of HCL is crucial to avoid delayed optimal therapy and to enhance patient outcomes. This case emphasizes the critical role of morphology and immunophenotyping in confirming HCL, especially in resource-limited countries.\n\nID: 42416339\nTitle: Effects of pole position and grip height on upper-body kinetics and throwing performance in paralympic seated shot put.\nAbstract: This study investigated the effects of pole position (horizontal distance from the seat) and pole grip height on kinetic parameters and throwing performance in Paralympic seated shot put. Four F33-34 athletes (1 national and 3 international levels) each performed 27 maximum-effort throws across nine pole configurations (3 pole positions\u2009\u00d7\u20093 grip heights) in a fully crossed within-subject design. Upper-body joint powers and pole forces were calculated using three-dimensional inverse dynamics and an instrumented throwing pole. Linear mixed models with random intercepts for athlete were used to assess the effects of pole position and grip height on 13 kinetic variables, with Benjamini-Hochberg false discovery rate correction. Within-athlete performance associations were tested for variables with significant pole configuration effects. A post-protocol fatigue check (three additional throws at each athlete's normal configuration) confirmed no significant performance decrement (d\u2009=\u20090.24). Pole position significantly affected seven of thirteen kinetic variables (all q\u2009<\u20090.05), including trunk axial rotation power (d\u2009=\u20091.15), throwing-arm shoulder power, and pole forces (posterior pole force d\u2009=\u20092.67). No grip height main effects or interactions survived correction. Despite these substantial kinetic changes, throw distance was not significantly affected by any pole configuration (marginal R2\u2009=\u20090.005). Of the seven significant variables, only mean lateral pole force was associated with within-athlete throw distance (\u03b2\u2009=\u2009-0.043\u2005m/N, q\u2009=\u20090.005), with a more laterally directed force linked to greater distance. Pole position is the primary equipment variable influencing kinetic strategy in seated shot put, while athletes maintain comparable throw distances through compensatory movement strategies. Mean lateral pole force is the sole kinetic variable that is both sensitive to pole position and predictive of performance, providing preliminary evidence that lateral pole force may be a useful candidate variable for individualised pole position selection, although the practical magnitude (within-athlete \u0394R2\u2009=\u20090.012) is modest. Pole configuration can be leveraged as a targeted training tool to modulate joint loading without compromising competitive performance.\n\nID: 42416308\nTitle: The influence of bruxism on post orthodontic direct anterior restorations integrity: a retrospective evaluation.\nAbstract: The aim of this study was to evaluate the influence of bruxism on post orthodontic direct anterior restorations integrity. In this retrospective study, adult subjects who received additive composite restorations in maxillary anterior teeth after an orthodontic treatment were recruited. Study group consisted of patients who reported fracture of the additive composite restorations, whereas controls were recruited among the patients who reported success, according to the modified United States Public Health Service (USPHS) criteria. A bruxism evaluation was performed according to the Standardized Tool for the Assessment of Bruxism (STAB). A Scanning Electron Microscopy evaluation was conducted to obtain a fractographic analysis. A total of 40 restorations from 20 patients (8 males and 12 females, mean aged 25.67\u2009\u00b1\u20094.77 years) were evaluated. The following electromyographic variables resulted to be significantly different between groups: PC (p-value\u2009=\u20090.003), TC (p-value\u2009=\u20090.003), MC (p-value\u2009=\u20090.002), and TMC (p-value\u2009=\u20090.000). The fractographic analysis revealed that the fractures originated at the site of traumatic contact with the antagonist tooth. At follow-up, patients with fractured anterior restorations showed significantly higher masseter muscle activity, evaluated in terms of phasic contractions, tonic contractions, mixed contractions, and total masseter contractions using a portable sEMG portable device. The fractographic analysis findings may be considered compatible with repetitive mechanical fatigue. The small sample size did not allow to draw robust conclusions. Future studies are needed on larger samples trying to identify the possible relationship between bruxism and anterior restorations fracture.\n\nID: 42416197\nTitle: Diagnostic Differentiation Between Unipolar and Bipolar Depression: A Machine Learning Analysis of Demographic and Clinical Features.\nAbstract: Differentiating between bipolar depression (BD) and unipolar depression (UD) presents a significant clinical challenge. Identifying the potential clinical features that distinguish between these two disorders is essential for optimizing personalized management strategies for individuals with depression. In this study, we employed machine learning to develop a classification model to distinguish between BD and UD based on demographic and clinical features. Patients with either BD or UD were included in this study. Three machine learning classifiers, including logistic regression (LR), random forest (RF), and support vector machine (SVM) were developed and compared using a dual evaluation strategy: (i) nested stratified cross-validation (5-fold outer, 3-fold inner) for unbiased model comparison; and (ii) an independent stratified hold-out split for final validation. In the latter phase, hyperparameters were optimized on the training set via grid search, with performance reported on the test set using bootstrapped 95% confidence intervals. Shapley Additive Explanations (SHAP) analysis was applied to the optimal model to elucidate feature importance. A total of 449 patients (239 UD and 210 BD) were included. All three models achieved a consistent area under the receiver operating characteristic curve (ROC-AUC) of approximately 0.78, indicating moderate discriminative capacity, with the RF model demonstrating a more balanced error distribution. The top six predictive features were: family history, age, sleep disturbance (Patient Health Questionnaire-9 [PHQ9] item 3), fatigue (PHQ9 item 4), use of sleep medication (Pittsburgh Sleep Quality Index [PSQI] item 6), and suicidal ideation (PHQ9 item 9). The SHAP analysis suggested that younger age, \"uncertain/unknown\" family history, and the use of sleep medication tended to push predictions toward BD, whereas suicidal ideation, sleep disturbance, and fatigue tended to push predictions toward UD. Our machine learning approach identified key predictors-including age, family history, and sleep-related symptoms-to differentiate UD from BD in adolescent and young adult patients. Although achieving moderate accuracy, the model may serve as a supportive screening tool to enhance clinical decision-making.\n\nID: 42416120\nTitle: Telehealth-Based Ketogenic Metabolic Therapy With Lifestyle Interventions for Post-viral Illness: A Research Brief of Patients' Experiences.\nAbstract: Infection-associated chronic illnesses are associated with substantial functional impairment that limits participation in traditional in-person research. A fully remote, multicomponent intervention that combines ketogenic metabolic therapy (KMT) with behavioral interventions targets several proposed biological mechanisms underlying these conditions. This study aimed to characterize patient-reported experiences with a fully remote intervention that integrated KMT and thiamine supplementation with behavioral strategies, including circadian entrainment and mindfulness-based resilience coaching. In this cross-sectional study, quantitative data were collected via online REDCap surveys. Feasibility and acceptability benchmarks included perceived treatment suitability, relevance, safety, and reported treatment adherence. Optimization items evaluated preferred program duration, dosing, and structure, as well as components that respondents identified as most important for future refinement. Among an international sample (n=41), all feasibility and acceptability benchmarks were met: 96% reported the intervention was helpful, 96% recommended it, and 75% felt \"a lot better\" after completion. Respondents provided patient-centered perspectives to optimize the intervention. Incorporating patient perspectives is essential for guiding the development of safe, acceptable, and effective treatment strategies for infection-associated chronic illness, including Long COVID. Strong indicators of feasibility, acceptability, and perceived benefits support the rationale for larger controlled trials to investigate clinical efficacy and the underlying mechanistic pathways of multicomponent metabolic interventions.\n\nID: 42416018\nTitle: Kefir-fermented soymilk reduces exercise-induced fatigue in mice by influencing the gut microbiota and short-chain fatty acid metabolism.\nAbstract: Fermented foods have obtained increasing attention because of their potential health advantages, particularly in modulating gut microbiota and metabolic functions. However, the impacts of fermented soymilk on exercise-induced fatigue and its basic mechanisms remain unclear. Here, mice were gavaged fermented soymilk (FM), unfermented soymilk (BM), or normal saline (Control) for 30 days, followed by an exhaustive swimming test. Fatigue-related biochemical parameters, antioxidant indices, gut microbiota composition, fecal short-chain fatty acids (SCFAs), and KEGG functional pathways were analyzed. FM significantly extended exhaustive swimming time compared with the Control and BM groups. It reduced serum LDH and BUN levels, increased glycogen storage, and improved antioxidant capacity, as indicated by elevated CAT activity and reduced MDA levels. FM markedly reshaped the gut microbiota by enriching SCFA-producing genera, including Blautia, Faecalibacterium, Dysosmobacter, Roseburia, and Lachnoclostridium, while reducing opportunistic pathogens. It enhanced carbohydrate and amino acid metabolism, as well as microbial interaction pathways, thereby promoting the synthesis of acetate and butyrate. These findings suggest that FM improves exercise performance and alleviates fatigue by enhancing energy metabolism, reducing oxidative stress, and modulating gut microbiota and its metabolic functions.\n\nID: 42415969\nTitle: Fatigue and Depression in Epilepsy Patients May Not be Solely Related to the Epilepsy Itself.\nAbstract: \n\nID: 42415774\nTitle: Prevalence of secondary traumatic stress in nurses: a meta-analysis of observational studies.\nAbstract: The reported prevalence of secondary traumatic stress (STS) among nurses varies considerably across studies, ranging from 22. 1 to 84.4%. This meta-analysis aimed to estimate the pooled prevalence of STS and identify potential moderating factors among nurses. From the inception of each target database to April 2026, a comprehensive search was performed across PubMed, Web of Science, Scopus, Embase, Cochrane Library, CINAHL, and PsycINFO. We calculated the pooled prevalence of STS using a random-effects model and assessed heterogeneity using the I2 statistic. Subgroup analyses and meta-regression were conducted to explore potential sources of heterogeneity. A total of 28 studies comprising 7,090 nurses were included. The pooled prevalence of STS in nurses was 57.3% (95% CI: 49.7-64.9%). STS prevalence was significantly associated with mean age (\u03b2 = -0.064, p = 0.023), work experience (\u03b2 = -0.080, p = 0.040), publication year (during COVID-19: \u03b2 = 0.979, p = 0.024; after COVID-19: \u03b2 = 0.848, p = 0.030), and geographic region (North America: \u03b2 = -0.881, p = 0.019; Europe: \u03b2 = -1.031, p = 0.005). Our findings indicated that STS was very prevalent in nurses, and the prevalence is moderated by mean age, work experience, publication year, and geographic region. Regular STS assessments and multi-level support systems, such as early warning, peer support, and mental health training, are recommended to reduce STS risk and enhance the wellbeing of nurses.\n\nID: 42415712\nTitle: Characteristics of Affected Limb Pain and Associated Factors in Young Adult Survivors of Lower Limb Osteosarcoma in Japan.\nAbstract: This study aimed to characterize affected-limb pain and its associated factors among adolescent and young adult (AYA) survivors of lower extremity osteosarcoma in Japan. We hypothesized that both physical and psychosocial factors would be associated with pain, with an interaction between pain intensity and pain interference. A cross-sectional study was conducted among osteosarcoma survivors aged 18-39 years who had completed treatment at least 2 years earlier. Self-administered questionnaires assessed pain intensity and interference, physical function, fatigue, sleep disturbance, anxiety, depression, and perceived social support. Multiple regression analyses were performed to identify factors associated with pain outcomes. Semistructured interviews were also conducted to provide supplementary insights into pain characteristics and contextualize the quantitative findings. Among 64 participants, 65.6% reported pain or pain interference during the preceding 7 days. Pain intensity was significantly associated with poorer physical function, older age at diagnosis, and lower perceived social support, whereas pain interference was primarily associated with greater fatigue severity. Pain intensity and pain interference were strongly correlated. Qualitative analysis identified four pain characteristics prosthesis-related pain, phantom limb pain, secondary pain, and weather-related pain. Interviews further illustrated how physical limitations, fatigue, and social support shaped pain experiences. Pain among long-term osteosarcoma survivors is influenced by multiple biopsychosocial factors. Although average pain severity was relatively mild, substantial interindividual variability was observed. Comprehensive survivorship care should address physical function, fatigue management, and social support to optimize long-term pain management and self-care among AYA osteosarcoma survivors.\n\nID: 42415537\nTitle: Factors associated with self-reported musculoskeletal symptoms among preschool teachers in Turkey.\nAbstract: BackgroundSelf-reported musculoskeletal symptoms (SRMSs) are common occupational health problems, particularly among preschool teachers due to physical and psychosocial demands. However, data on their prevalence and associated factors in Turkey are limited to a few studies.ObjectiveTo investigate the prevalence of SRMSs and associated psychosocial factors among Turkish preschool teachers.MethodsThis cross-sectional study included 304 preschool teachers in Turkey. The Expanded Nordic Musculoskeletal Questionnaire was used to determine the prevalence of SRMSs in the previous 4 weeks (SRMSs-4w) and the previous 12 months (SRMSs-12m). Depression levels were assessed using the Beck Depression Inventory (BDI), quality of life was assessed using the Short Form-36 scale (SF-36), physical activity was assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).ResultsThe prevalence of SRMSs-12m and SRMSs-4w among Turkish preschool teachers was 57.2% and 54.9%, respectively. SRMSs-12m and SRMSs-4w were most commonly reported in the neck (35.5% and 34.9%), lower back (34.9% and 32.2%), shoulders (30.3% and 26.6%), and upper back (25.7% and 20.7%). BDI, SF-36 (energy/fatigue, pain, general health), PSQI, and IPAQ-SF were independently associated with 4-week SRMSs, while BDI, SF-36 (pain, general health), and PSQI were independently associated with 12-month SRMSs (p\u2009<\u20090.05).ConclusionsThe results showed a high prevalence of SRMSs among Turkish preschool teachers. SRMS prevalence was highest in the neck, lower back and shoulder regions. Furthermore, this study demonstrated associations between depression levels, quality of life, sleep quality, physical activity level, and SRMSs in preschool teachers.\n\nID: 42415533\nTitle: Intraoperative OR-Stretch Microbreaks: A pre-implementation study on two break scheduling strategies.\nAbstract: BackgroundSurgeons face elevated risks of musculoskeletal disorders due to prolonged operating times, awkward postures, and repetitive tasks, which can impair performance and well-being. Microbreaks have emerged as a potential ergonomic intervention to reduce discomfort and fatigue during surgery.ObjectiveThe main goal of this study was to investigate and compare the intraoperative usability and effectiveness of two break scheduling strategies using the OR-StretchTM Web-App. Furthermore, surgeons' feedback on the primary barriers to implementation of the OR-Stretch Web-App was recorded.MethodsThis study used a randomized, within-subjects crossover design. Fourteen surgeons (eight females) performed three surgical procedures with the following microbreak schedules; (1) microbreaks every 30\u2005min with an optional ten-minute snooze (Break-30), (2) microbreaks every 60\u2005min with an optional ten-minute snooze (Break-60), or (3) no microbreaks (Baseline). Outcomes were measured using self-reported subjective surveys (e.g., discomfort, fatigue, workload, and usability).ResultsSurgeons found both Break-30 and Break-60 conditions aided physical performance, mental focus, body pain/discomfort, and level of fatigue (self-reported improvement between 28.6% and 78.6%). No significant differences were observed in surgeons' subjective evaluations of the Break-30 and Break-60 conditions; however, the data suggest that Break-60 is preferable to the Break-30 condition.ConclusionsThis study provides evidence supporting the OR-Stretch Web-App as a potential surgical ergonomic intervention. However, enhancing the Web-App's user-friendliness and developing strategies to synchronize microbreaks with appropriate times during surgeries, to avoid disrupting the surgical workflow, are critical areas for future studies.\n\nID: 42415310\nTitle: Development of the inventory of clinician attitudes about suicide prevention.\nAbstract: Mental health providers (MHPs) hold varying attitudes about suicide prevention, and these beliefs can impact personal and client well-being. To date, suicide prevention attitude measures are limited by appropriate population use, poor psychometrics and a lack of theoretical foundation. The present study rectified a measurement gap in the literature by articulating initial development of the Inventory of Clinician Attitudes about Suicide Prevention (ICASP). MHPs (N\u2009=\u2009410) across three countries (United States, Canada and Australia) took part in a cross-sectional online survey about suicide prevention competencies. A community-engaged convenience sampling approach was used followed by splitting the sample to perform parallel exploratory factor analysis and item response theory analyses. Analyses yield a four-factor ICASP with 22 items: (1) Clinician's Approach (\u03c9\u2009=\u20090.79); (2) Clinician Avoidance (\u03c9\u2009=\u20090.76); (3) Moral Rights (\u03c9\u2009=\u20090.84); and (4) Clinician Comfort (\u03c9\u2009=\u20090.72). Exploratory findings suggest convergent validity via significant, yet modestly sized, correlations with attitudes glorifying suicide and three elements of compassion fatigue (i.e. compassion satisfaction, burnout and secondary traumatic stress). The ICASP represents a promising tool for measurement of MHP suicide prevention attitudes in clinical supervision, self-reflective practice and training evaluation. Findings support portions of the Dynamic Balance Model of MHP suicide prevention attitudes. Future psychometric research directions are discussed.\n\nID: 42415135\nTitle: Association of functional and social factors with domain-specific quality of life profiles in children with cerebral palsy: findings from a low- and middle-income country.\nAbstract: To evaluate domain-specific quality of life and its associations with functional severity, selected comorbidities, and social factors among children with cerebral palsy attending a tertiary referral centre in Sri Lanka. Among 223 children, 61.9% were male and the mean age was 6.99 years. Quality-of-life scores varied markedly across domains. Daily activities, school activities, movement and balance, eating activities, and speech and communication showed wide score dispersion, whereas pain and fatigue showed ceiling effects. Scores declined progressively with increasing Gross Motor Function Classification System level across analysed domains, with strong monotonic trends observed (Kendall's \u03c4\u2009-\u20090.57 to -\u20090.72; all p\u2009<\u20090.001). Epilepsy, cognitive impairment, cortico-visual impairment, hearing impairment, and gastro-oesophageal reflux disease were associated with lower overall or domain-specific scores in unadjusted analyses. In adjusted models focused on measured social factors, age, sex, living arrangement, and parental education were not independently associated with the analysed domain scores. Domain-level assessment may provide clinically informative quality-of-life profiles that are not captured by overall scores alone.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

While many symptoms are likely nonspecific, a recurring cluster, including severe fatigue, brain fog, cognitive decline, memory impairment, joint and muscle pain, limb numbness, headaches, and low-grade fever, is often labeled in the scientific literature as post-treatment Lyme disease syndrome (PTLDS), and in the popular media as \"chronic Lyme disease.\" Based on clinical experience and retrospective case analysis, this study hypothesizes that in many such cases, these persistent symptoms are not sequelae of Lyme borreliosis but manifestations of an undiagnosed focal infection, most commonly chronic tonsillitis or periodontal disease. The hypothesis is supported by the observation that the symptom profile of PTLDS is remarkably similar to that seen in focal infections, and by documented patient outcomes following treatment of these localized infections. This study compiles and analyzes clinical data to support the reinterpretation of PTLDS and \"chronic Lyme disease\" as misattributed focal infections in a subset of patients.\n  --- END ACTUAL ABSTRACT FOR 41024925 ---\n\n- ERROR: You cited ID: 40985958 for the quote: \"No serious adverse events were reported... findings suggest that KY significantly improves memory, executive functioning... and modestly improves fatigue.\"\n  FACT: Ellipses (...) are strictly forbidden.

Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Can post-lyme disease syndrome be cured?\"\nThe current scientific consensus, as reflected in the provided literature, indicates that PTLDS is a poorly understood syndrome for which no evidence-based \"cure\" currently exists. Treatment is predominantly management-focused rather than curative.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nWhile antibiotic therapy is highly effective for initial *Borrelia burgdorferi* infection, a subset of patients (10-20%) develop persistent symptoms (PTLDS). Evidence-based medicine currently lacks a curative regimen for PTLDS, with major clinical guidelines advising against long-term antibiotic or immunomodulatory therapy due to lack of demonstrated efficacy and risk of adverse effects. Management emphasizes a multidisciplinary, symptom-focused approach.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe management of Post-Treatment Lyme Disease Syndrome (PTLDS) remains one of the most significant challenges in modern infectious disease medicine. While clinical guidelines confirm that antibiotics are essential for the primary treatment of Lyme borreliosis, they do not resolve the post-infectious manifestations observed in a significant minority of patients. As stated in the provided literature, \"Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects.\" The persistence of symptoms such as fatigue, cognitive impairment, and diffuse pain, often lasting beyond six months, suggests a complex pathology that is not simply a residual infection. Consequently, clinical strategies have shifted toward symptom management, including physical rehabilitation and psychological support.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Current diagnostic markers are non-existent; PTLDS is currently diagnosed clinically based on symptoms following treated infection.\n*   \"Chronic Lyme disease\" is often used in popular media, but professional bodies like the IDSA prefer the term PTLDS to describe this specific post-treatment sequela.\n*   Persistent symptoms are not consistently linked to current/ongoing spirochete presence, leading to hypotheses regarding autoimmune responses or tissue damage.\n*   Symptoms of PTLDS share high phenotypic similarity with other infection-associated chronic conditions (IACCI) such as Long COVID and ME/CFS.\n*   There is a significant psychological and economic burden, with patients often \"wandering from specialty to specialty\" in search of diagnosis and relief.\n*   Therapeutic trials, including those for TPE (therapeutic plasma exchange), have largely failed in unselected populations, suggesting the future of treatment lies in biomarker-guided patient stratification.\n*   Recent research has begun to investigate mind-body interventions, such as online yoga, which have shown feasibility and benefits for symptom burden management.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences."

The pathogenesis, ecology, and epidemiology of Lyme disease have been well described, and antimicrobial treatment is very effective. There has been controversy about whether infection can persist and cause chronic symptoms despite treatment with antimicrobials. This review summarizes recent studies that have addressed this issue. The pathogenesis of persistent nonspecific symptoms in patients who were treated for Lyme disease is poorly understood, and the validity of results of attempts to demonstrate persistent infection with B. burgdorferi has not been established. One study attempted to use xenodiagnosis to detect B. burgdorferi in patients who have been treated for Lyme disease. Another study assessed whether repeated episodes of erythema migrans were due to the same or different strains of B. burgdorferi. A possible cause of persistent arthritis in some treated patients is slow clearance of nonviable organisms that may lead to prolonged inflammation. The results of all of these studies continue to provide evidence that viable B. burgdorferi do not persist in patients who receive conventional antimicrobial treatment for Lyme disease. Patients with persistent symptoms possibly associated with Lyme disease often provide a challenge for clinicians. Recent studies have provided additional evidence that viable B. burgdorferi do not persist after conventional treatment with antimicrobials, indicating that ongoing symptoms in patients who received conventional treatment for Lyme disease should not be attributed to persistent active infection."

This condition is called post-Lyme disease syndrome (PLDS) or post-treatment Lyme disease syndrome. These two terms are used interchangeably. The pathogenesis of PLDS has been controversial. The hypothesis that patients with PLDS may harbor hidden reservoirs of Borrelia burgdorferi after their initial antibiotic treatment is difficult to accept. The prospective, double-blind studies contradict this point of view. Also, recently published research applying xenodiagnosis to PLDS supports the opinion that PLDS most likely has an autoimmune background. Lengthy courses of antibiotics are not justified in patients with PLDS because of the lack of benefit, and they are fraught with hazards. Most patients with PLDS recover from persistent symptoms with time. However, it can take months before they feel completely well."

This is exacerbated by the lack of a clinical or microbiologic definition, and the commonality of chronic symptoms in the general population. An accumulating body of evidence suggests that Lyme disease is the appropriate diagnosis for only a minority of patients in whom it is suspected. In prospective studies of Lyme disease, very few patients go on to have a chronic syndrome dominated by subjective complaints. There is no systematic evidence that Borrelia burgdorferi, the etiology of Lyme disease, can be identified in patients with chronic symptoms following treated Lyme disease. Multiple prospective trials have revealed that prolonged courses of antibiotics neither prevent nor alleviate such post-Lyme syndromes. Extended courses of intravenous antibiotics have resulted in severe adverse events, which in light of their lack of efficacy, make them contraindicated."

These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues."

Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed."

Transmission occurs primarily through the bite of an infected deer tick (Ixodes scapularis). Identification of an erythema migrans rash following a tick bite is the only clinical manifestation sufficient to make the diagnosis of Lyme disease in the absence of laboratory confirmation. The Centers for Disease Control and Prevention recommends a two-tier serologic testing protocol using an enzyme-linked immunosorbent assay initially, followed by the more specific Western blot to confirm the diagnosis when the assay samples are positive or equivocal. The treatment of Lyme disease is determined mainly by the clinical manifestations of the disease. Doxycycline is often the preferred agent for oral treatment because of its activity against other tick-borne illnesses. Preventive measures include avoiding areas with high tick burdens, wearing protective clothing, using tick repellants (e.g., diethyltoluamide [DEET]), performing frequent body checks and bathing following outdoor activities, and instituting environmental landscape modifications (e.g., grass mowing, deer exclusion fencing) to reduce the tick burden. Although there is controversy regarding treatment of post-Lyme disease syndrome and chronic Lyme disease, there is no biologic or clinical trial evidence indicating that prolonged antibiotic therapy is of benefit."

The following three criteria should be fulfilled for definite LNB, and two of them for possible LNB: (i) neurological symptoms; (ii) cerebrospinal fluid (CSF) pleocytosis; (iii) Bb-specific antibodies produced intrathecally. PCR and CSF culture may be corroborative if symptom duration is <6 weeks, when Bb antibodies may be absent. PCR is otherwise not recommended. There is also not enough evidence to recommend the following tests for diagnostic purposes: microscope-based assays, chemokine CXCL13, antigen detection, immune complexes, lymphocyte transformation test, cyst formation, lymphocyte markers. Adult patients with definite or possible acute LNB (symptom duration <6 months) should be offered a single 14-day course of antibiotic treatment. Oral doxycycline (200 mg daily) and intravenous (IV) ceftriaxone (2 g daily) are equally effective in patients with symptoms confined to the peripheral nervous system, including meningitis (level A). Patients with CNS manifestations should be treated with IV ceftriaxone (2 g daily) for 14 days and late LNB (symptom duration >6 months) for 3 weeks (good practice points). Children should be treated as adults, except that doxycycline is contraindicated under 8 years of age (nine in some countries). If symptoms persist for more than 6 months after standard treatment, the condition is often termed post-Lyme disease syndrome (PLDS). Antibiotic therapy has no impact on PLDS (level A)."

It is a common illness in temperate countries, especially the United States, but the incidence is increasing across continents due to increasing reforestation, travel and adventure tourism, increased intrusion in the vector habitat, and changing habitat of the vector. Transmission primarily occurs via bite of an infected tick (Ixodes spp.). The appearance of an erythema migrans rash following a tick bite is diagnostic of early Lyme disease even without laboratory evidence. Borrelia lymphocytoma and acrodermatitis chronica atrophicans along with multisystem involvement occur in late disseminated and chronic stages. A two-step serologic testing protocol using an enzyme-linked immunosorbent assay (ELISA) followed by confirmation of positive and equivocal results by Western immunoblot is recommended for the diagnosis. Transplacental transmission to infant occurs in the first trimester with possible congenital Lyme disease making treatment imperative during antenatal period. The treatment is most effective in the early stages of the disease, whereas rheumatological, neurological, or other late manifestations remain difficult to treat with antibiotics alone. Treatment with oral doxycycline is preferred for its additional activity against other tick-borne illnesses which may occur concurrently in 10%-15% of cases. New-generation cephalosporins and azithromycin are alternative options in patients with doxycycline contraindications. No vaccine is available and one episode of the disease will not confer life-long immunity; thus, preventive measures remain a priority. The concept of post-Lyme disease syndrome versus chronic Lyme disease remains contested for want of robust evidence favoring benefits of prolonged antibiotic therapy."

While most patients successfully recover with antibiotics, some patients experience persistent symptoms for months to years. Patients who attribute chronic symptoms to Lyme disease commonly use herbal supplements. The complexity, variability in dose and formulation, and lack of data for these herbal compounds make it difficult to assess their efficacy and safety. This review examines the evidence for the antimicrobial activity, safety, and drug-drug interactions of 18 herbal supplements that patients commonly use for treatment of persistent symptoms attributed to Lyme disease. The research team performed a narrative review by searching the PubMed, Embase, Scopus, Natural Medicines databases, and NCCIH website. The search used the keywords for 18 herbal compounds: (1) andrographis (Andrographis paniculate), (2) astragalus (Astragalus propinquus), (3) berberine, (4) cat's claw bark (Uncaria tomentosa), (5) cordyceps (Cordyceps sinensis), (6) cryptolepis (Cryptolepis sanguinolenta), (7) Chinese skullcap (Scutellaria baicalensis), (8) garlic (Allium sativum), (9) Japanese knotwood (Polygonum cuspidatum), (10) reishi mushrooms (Ganoderma lucidum), (11) sarsaparilla (Smilax medica), (12) Siberian ginseng (Eleutherococcus senticosus), (13) sweet wormwood (Artemisia annua), (14) teasle root (Dipsacus fullonum), (15) lemon balm (Melissa officinalis), (16) oil of oregano (Origanum vulgare), (17) peppermint (Mentha x piperita), and (18) thyme (Thymus vulgaris). The team also searched for terms related to protocols, including Dr. Rawls' protocol and the Buhner protocol. University of Maryland Medical Center, Baltimore MD. Seven of the 18 herbs reviewed had evidence for in-vitro activity against B. burgdorferi. These compounds included: (1) cat's claw (2) cryptolepis, (3) Chinese skullcap, (4) Japanese knotweed, (5) sweet wormwood, (6) thyme, and (7) oil of oregano. With the exception of oil of oregano these compounds also have anti-inflammatory activity. In vivo data and clinical trials are lacking. Clinicians should be cautious as many of the identified compounds have drug interactions and additive effects that could lead to increased risks for bleeding, hypotension, and hypoglycemia. Many of the herbs that alternative and integrative practitioners use to treat Lyme disease have anti-inflammatory effects that may contribute to patients' perceptions of symptomatic improvement. Some herbs have limited demonstrated anti-borrelial activity in vitro, but in-vivo data and clinical trial data is lacking. Further research is required to determine the efficacy, safety and appropriate use of these herbs for this patient population."

Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms."

Assessments were made at 90 and 180 days after treatment. Symptom severity was measured from the cognitive functioning, pain, and role functioning scales of the Medical Outcomes Study (MOS). Memory, attention, and executive functioning were assessed using objective tests. Mood was assessed using the Beck Depression Inventory and Minnesota Multiphasic Personality Inventory. There were no significant baseline differences between seropositive and seronegative groups. Both groups reported a high frequency of MOS symptoms, depression, and somatic complaints but had normal baseline neuropsychological test scores. The combined groups showed significant decreases in MOS symptoms, higher objective test scores, and improved mood between baseline and 90 days. However, there were no significant differences between those receiving antibiotics and placebo.

In some patients, however, problems persist for a long time despite appropriate therapy. The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome."

PROMIS 29 scores showed the greatest improvement in fatigue at -7.91 (95% CI\u2009=\u2009-12.34 to -3.48; p\u2009<\u20090.001), pain interference -5.08 (95% CI\u2009=\u2009-9.20 to -0.96; p\u2009=\u20090.016), and ability to participate in social roles and activities 7.48 (95% CI\u2009=\u20093.21-11.75; p\u2009=\u20090.001) and least with depression -1.82 (95% CI\u2009=\u2009-4.74 to 1.10; p\u2009=\u20090.223). Employment status had significant effects on almost all outcome scores. Postinfectious state was associated with improvement in anxiety and PSS scores. Conclusions: A multimodal Ayurvedic and breath-coordinated mind-body therapeutic intervention is feasible and a potential nonpharmacologic therapeutic option for persons presenting with pain, stress, fatigue, physical dysfunction, and sleep disturbance attributed to a postinfectious syndrome. Further research is needed to determine efficacy in this population and in other groups with similar symptom complexes due to postinfectious syndromes."

Based on the provided literature, there is no clinical evidence to support the existence of a \"cure\" for this syndrome. Controlled trials consistently indicate that prolonged antibiotic therapy provides no sustained benefit and carries significant risks of adverse events. Current management strategies emphasize symptom relief and multidisciplinary, non-pharmacological support.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a medically contested entity due to the absence of well-defined diagnostic biomarkers and the lack of evidence for persistent active infection. Multiple systematic reviews and randomized controlled trials (RCTs) have demonstrated that prolonged courses of antibiotics, often used for \"chronic Lyme disease,\" are ineffective for PTLDS and frequently result in serious adverse outcomes, such as infections and hospitalizations. \n\nThe literature underscores that the pathophysiology of PTLDS is poorly understood, with hypotheses ranging from autoimmune responses, permanent tissue damage, or allostatic load to the existence of nonviable antigenic debris. Given the lack of a causative agent or a consistent pathomechanism, no definitive \"cure\" exists in current clinical practice. Instead, research has shifted toward feasibility studies for non-pharmacological interventions, such as online yoga and Ayurveda-based mind-body practices, which may assist in managing symptom burden and improving quality of life, rather than eliminating the syndrome itself.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Evidence suggests that prolonged antibiotic therapy does not address the core symptoms of PTLDS and can introduce significant morbidity.\n*   Diagnosis of PTLDS is purely clinical, as no quantifiable laboratory methods exist to verify the syndrome's presence or resolution.\n*   Some patients diagnosed with \"chronic Lyme disease\" may actually be suffering from other, distinct conditions such as fibromyalgia, chronic fatigue syndrome, or depression.\n*   The prevalence of PTLDS is estimated to occur in approximately 10\u201320% of adequately treated Lyme patients.\n*   Emerging research into MSA/MAA autoantibodies in PTLDS patients points toward potential immune dysregulation as a pathogenetic factor rather than persistent infection.\n*   Yoga and mind-body interventions have demonstrated feasibility and potential in reducing pain and cognitive impairment in PTLDS cohorts.\n*   Misattribution of focal infections (like tonsillitis) as \"chronic Lyme disease\" is a documented source of diagnostic error.\n*   The medical literature explicitly cautions against the use of central venous catheters for long-term antibiotic administration due to risks of serious infections, such as *Mycobacterium goodii*.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions.\n\nID: 42359130\nTitle: Patient roadmap and economic burden of chronic tick-borne illness and post-treatment Lyme disease syndrome in Ireland, and public health issues arising.\nAbstract: Lyme borreliosis (LB), commonly referred to as Lyme disease (LD), is a prominent global health issue, exhibiting a seroprevalence rate of 14.5%. Heightened incidence levels of LD have been recorded in parts of Europe, Poland, Eastern Europe, and the Baltic States. The research aimed to inform the cost of LD and post-treatment Lyme disease syndrome (PTLDS) in Ireland through results from a patient questionnaire, disease modelling, the construction of a patient roadmap, and attempts to arrive at prevalence calculation estimates based on local data. Patient data encompassed sociodemographic particulars, disease attributes, healthcare resource utilization, and the influence on their employment status. Of 301 patients, 210 were diagnosed with LD and/or a tick-borne infection (TBI), the cohort's average age was 40.07 (SD 13.5) (N\u202f=\u202f210; Female:Male 60:40). The mean duration of symptoms in PTLDS patients was 7.15\u202fyears. The average number of visits to other healthcare professionals was 16.8 per patient. Regarding current employment status, the data indicates that 50.2% of respondents were currently working, 10.1% were unemployed, 8.7% were retired, 5.3% had caring responsibilities, 11.1% were on sick leave, and 14.5% fell into the \"Other\" category. Additionally, when asked if symptoms had affected their employment status, 69% of respondents said yes, 26% said no, and 5% did not respond. Modeling efforts show that the roadmap to care for PTLDS is challenging, leading to wandering from specialty to specialty and high healthcare utilization. Utilizing a novel method of indirect reverse estimation, our lifetime risk or cumulative incidence of PTLDS estimation is at 0.003%. Lack of data collection from Irish health authorities is leaving the issue of the cost of LD and PTLDS hard to address, despite efforts from our single-site study.\n\nID: 42148664\nTitle: Designing studies for post-treatment Lyme disease and other infection-associated chronic illnesses.\nAbstract: Infection-associated chronic illnesses (IACIs) encompass a spectrum of poorly understood syndromes often marked by significant neurologic and multisystem symptoms following an infectious event. This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs.\n\nID: 41972549\nTitle: In Silico-Identified Peptides of Five Borrelia burgdorferi Proteins Binding with High Affinity to Human Leukocyte Antigen (HLA) Class II Alleles.\nAbstract: To date, Lyme vaccine development has largely overlooked the vaccinee's human leukocyte antigen (HLA) genetic makeup on which antibody production critically depends. Here, we evaluated in silico the predicted binding affinities of 192 HLA-II alleles with all 15-mer peptide sequences of five Borrelia burgdorferi proteins to identify peptides with strong binding affinity, as they would be the best candidates for antibody production in response to vaccination. We found the following: (a) 226 of the 1067 peptides tested (21.2%) were found to bind strongly to HLA-II molecules; (b) decorin-binding protein A had the greatest number of strongly binding peptides; and (c) 69 HLA-II alleles (primarily of the DRB1 gene) bound with strong affinity to peptides from Borrelia burgdorferi proteins. Finally, we tested for possible susceptibility to autoimmunity by any one of the 226 peptides above by searching for their occurrence in ~84,000 proteins of the human proteome and found overlap with only two 8-mer peptide sequences (embedded within the 226 15-mer peptides), neither of which was characterized by strong binding to HLA-I, suggesting a reduced likelihood of autoimmunity. These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety. The results of this computational study provide novel directions for future development of Lyme vaccines.\n\nID: 41826406\nTitle: Evaluation of immunoreactive epitopes in the sera and cerebrospinal fluid of patients with post-treatment Lyme disease syndrome.\nAbstract: While most patients fully recover after treatment for Lyme disease with recommended antibiotic regimens, some report non-specific symptoms after treatment. When these symptoms are unexplained by other conditions and persist for \u2265\u20096 months, this condition is called post-treatment Lyme disease symptoms or syndrome (PTLDS). The pathogenesis of PTLDS is unknown and no specific diagnostic biomarkers have been identified. In this study, we used a high-density peptide array to examine antibody responses to >\u200960 primary antigens of B. burgdorferi from a cohort of patients diagnosed with PTLDS and recovered patients with similar Lyme disease manifestations. Using matched serum and cerebrospinal fluid (CSF), we mapped the primary reactive B. burgdorferi epitopes associated with PTLDS. We found that VlsE had a greater antibody response within the PTLDS cohort than recovered patients. The reactivity to OspC-specific epitopes revealed a predominance of antibodies to OspC type K and A in the PTLDS cohort. However, the major immunodominant epitopes were similar in PTLDS and recovered patients, and we were unable to identify specific diagnostic targets for PTLDS. We found a more robust reactivity in the serum over CSF and did not identify antigenic regions that were specifically associated with the infection of the central nervous system.\n\nID: 41796643\nTitle: Feasibility and preliminary efficacy of an online yoga program for managing symptoms of post-treatment lyme disease syndrome.\nAbstract: We evaluated the feasibility and efficacy of a 12-week synchronous online yoga program for managing post-treatment Lyme disease syndrome (PTLDS) symptoms, focusing on pain, physical functioning, and cognitive performance. Thirteen participants with PTLDS (aged 21-60 years; 92% female) participated in 75-minute weekly sessions led by certified yoga instructors, with 15-20\u202fmin of daily homework on five non-treatment days. Outcome measures included the Health-Related Quality of Life - Short Form (SF-36), Brief Pain Inventory (BPI), and the Cambridge Neuropsychological Test Automated Battery (CANTAB). The primary feasibility goals were met with a retention rate of 92.50%, treatment adherence of 82.70%, and a treatment satisfaction score of 3.4/4. The missing data rate was low at 3.90%. Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms.\n\nID: 41570190\nTitle: Nonspecific Symptoms Attributable to Lyme Disease in High-Incidence Areas, United States, 2017-2021.\nAbstract: For some patients who have Lyme disease (LD), nonspecific symptoms can persist after treatment and impair quality of life. Estimating the frequency and duration of such symptoms is challenging. Using commercial insurance claims data from 2017-2021 for enrollees residing in states where LD is common, we identified 24,503 case-patients with LD and matched them (1:5) with 122,095 control-patients with other diagnoses by demographics, medical service date, and inpatient/outpatient setting. We compared relative frequencies of diagnosis codes for pain, fatigue, and cognitive difficulties between case-patients and control-patients in the year after diagnosis. Those symptom codes occurred 5.0% more frequently among case-patients than among control-patients and comprised \u00bb11.0% of the total symptom codes among case-patients. Symptom code frequency among case-patients declined significantly in the 6-12 months after LD diagnosis and reached levels similar to control-patients by the end of the year, with the exception of fatigue.\n\nID: 41421419\nTitle: Methemoglobinemia induced by dapsone, hydroxychloroquine, and rifampin combination for post-treatment Lyme disease syndrome: A case report.\nAbstract: A patient presented to the emergency department with drug-induced methemoglobinemia due to a combination of medications prescribed for post-treatment Lyme disease syndrome (PTLDS). This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination.\n\nID: 41314472\nTitle: Guidelines for Lyme borreliosis: post-treatment Lyme disease syndrome (PTLDS).\nAbstract: Persistent symptoms following appropriate treatment of confirmed Lyme borreliosis (LB) require a systematic clinical reassessment. The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences.\n\nID: 41195425\nTitle: Guidelines for diagnosis and treatment in neurology - Lyme neuroborreliosis.\nAbstract: Lyme disease is the most common tick-borne infectious disease in Europe. Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy. Die Lyme-Borreliose ist die h\u00e4ufigste durch Zecken \u00fcbertragene Infektionskrankheit in Europa. Eine neurologische Manifestation kommt bei 3\u201315% der Infektionen vor und kann sich als Polyradikulitis, Meningitis sowie selten als Enzephalomyelitis manifestieren. Die Erkrankung ist durch Antibiotika behandelbar. Die bisher g\u00fcltige S3-Leitlinie \u201eNeuroborreliose\u201c wurde entsprechend den methodischen Vorgaben der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V. (AWMF-Registernr. 030/071) aktualisiert. An der Aktualisierung waren 18 AWMF-Mitgliedsgesellschaften, das Robert Koch-Institut, die Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie, die Schweizerische Neurologische Gesellschaft, die \u00d6sterreichische Gesellschaft f\u00fcr Neurologie, die Deutsche Borreliose-Gesellschaft und 2 Patientenorganisationen beteiligt. Die Leitlinie richtet sich an \u00c4rzte in Praxis und Klinik, die mit der Behandlung der Neuroborreliose bei Kindern und Erwachsenen befasst sind. Erstmals liegt jetzt eine Klasse-Ia-Evidenz vor, dass eine 14-t\u00e4gige Dauer der Antibiotikagabe bei fr\u00fcher Neuroborreliose therapeutisch ausreichend ist. Neu ist au\u00dferdem, dass eine Steroidgabe zus\u00e4tzlich zur Antibiotikatherapie bei Fazialisparese im Rahmen einer entsprechend den Diagnosekriterien wahrscheinlichen oder gesicherten Neuroborreliose nicht empfohlen wird und dass die Altersbegrenzung f\u00fcr Doxycyclin bei Kindern unter 8 Jahren zur Therapie der Neuroborreliose entf\u00e4llt. \u00dcber die Wirksamkeit von Antibiotika-Kombinationsbehandlungen liegen weiterhin keine validen Studiendaten vor. Im Rahmen eines systematischen Reviews zur Therapie des sogenannten Post-Treatment Lyme Disease Syndrome (PTLDS) zeigte sich, dass die untersuchten Parameter Lebensqualit\u00e4t, Fatigue, Depression und Kognition nicht auf eine antibiotische Therapie ansprechen. F\u00fcr die Wirksamkeit anderer Therapieverfahren fanden sich keine aussagekr\u00e4ftigen Studien.\n\nID: 41136524\nTitle: HLA and pathogens in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and other post-infection conditions.\nAbstract: Viral infections have been widely implicated in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) pathogenesis. Recent evidence has also identified certain Human Leukocyte Antigen (HLA) alleles that are significantly associated with ME/CFS risk/protection. Here we tested the hypothesis that ME/CFS risk or protection conferred from those HLA alleles is associated with binding affinity to antigens of HHV viruses, a critical step in initiating the adaptive immune system response to foreign antigens. Specifically, we determined in silico the predicted binding affinity of two susceptibility alleles (C*07:04, DQB1*03:03) and two protective alleles (B*08:01, DPB1*02:01) to >\u200910,000 antigens of the 9 Human Herpes Viruses (HHV1, HHV2, HHV3, HHV4, HHV5, HHV6A, HHV6B, HHV7, HHV8) which have been implicated in the etiology of ME/CFS. We found that the binding affinity of all HHV antigens to the susceptibility alleles was significantly weaker than the binding affinity to the protective alleles (P\u2009<\u20090.001). In fact, none of the HHV antigens showed strong binding to the susceptibility alleles, in contrast to the strong bindings showed by the protective alleles. These findings are in keeping with the hypothesis that the effect of a putative HHV insult in contributing to ME/CFS is modulated by the host's HLA immunogenetic makeup. We speculate that strong HLA-antigen binding likely protects against ME/CFS via elimination of virus antigens; conversely, weak HLA-antigen binding may permit persistence of foreign antigens, contributing to ME/CFS and other chronic conditions. Finally, with respect to the latter, we determined the binding affinities to the 4 HLA alleles above to pathogens causing two chronic diseases with very similar symptomatology to ME/CFS, namely Long COVID and post-treatment Lyme disease syndrome (PTLDS). We found that the 2 ME/CFS susceptibility HLA alleles above had very weak binding with SARS-CoV-2 virus glycoprotein (involved in Long COVID) and 5 proteins of Borrelia burgdorferi (involved in PTLDS), in contrast to the ME/CFS protective alleles that showed strong bindings. These findings support the hypothesis that ME/CFS, long COVID and PTLDS are caused by persistent pathogenic antigens that could not be eliminated due to inadequate protection by the patient's HLA makeup.\n\nID: 41024925\nTitle: Reassessing Chronic Lyme Disease and Post-Treatment Lyme Disease Syndrome as Focal Infections.\nAbstract: The complete clinical spectrum of Lyme borreliosis has been recognized for nearly 50 years, yet its diagnosis remains challenging due to the heterogeneity of symptoms. While many symptoms are likely nonspecific, a recurring cluster, including severe fatigue, brain fog, cognitive decline, memory impairment, joint and muscle pain, limb numbness, headaches, and low-grade fever, is often labeled in the scientific literature as post-treatment Lyme disease syndrome (PTLDS), and in the popular media as \"chronic Lyme disease.\" Based on clinical experience and retrospective case analysis, this study hypothesizes that in many such cases, these persistent symptoms are not sequelae of Lyme borreliosis but manifestations of an undiagnosed focal infection, most commonly chronic tonsillitis or periodontal disease. The hypothesis is supported by the observation that the symptom profile of PTLDS is remarkably similar to that seen in focal infections, and by documented patient outcomes following treatment of these localized infections. This study compiles and analyzes clinical data to support the reinterpretation of PTLDS and \"chronic Lyme disease\" as misattributed focal infections in a subset of patients.\n\nID: 40985958\nTitle: Evidence-Based Clinical Effectiveness of Kundalini Yoga: Systematic Review of RCTs Across Multiple Health Conditions.\nAbstract: Kundalini Yoga (KY) integrates breathwork, meditation, dynamic movement, and chanting, and has gained recognition as a therapeutic intervention. Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes. KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions. However, larger, standardized RCTs with active comparators, biomarkers, and longer follow-up are needed.

Disulfiram (DIS), a drug for alcoholism, is under investigation as a potential adjunctive treatment, but its low bioavailability, rapid metabolism, and safety concerns urge the development of improved formulations for clinical translation. Methods: Screening dissolution and permeation studies were investigated for vehicle and excipient selection, following the pharmacopeia perspectives to develop and optimize the low-dose DIS rectal suppository intended for application in post-treatment Lyme disease syndrome (PTLDS). Further characterizations were carried out by differential scanning calorimetry, X-ray diffraction, and infrared spectroscopy. Results: Cyclodextrin (CD) encapsulation was investigated to improve the aqueous solubility of the hydrophobic drug. The dissolution of DIS from fatty base suppository was very slow; it was remarkably improved by the molecular encapsulation of the drug with CDs. The dissolution of DIS from a water-soluble base was more favorable, but incomplete. In the polyethylene glycol (PEG) based suppositories, the addition of CDs already in a physical mixture ensured the dissolution of the drug. The presented drug delivery system relates to a novel preparation for rectal administration comprising a low-dose disulfiram with improved solubility and permeability by the PEG and hydroxypropyl-\u03b2-cyclodextrin (HPBCD) synergistic matrix. Conclusions: The rectal dosage form containing the drug and CD in the physical mixture is advantageous, avoiding the hepatic first-pass effect, minimizing dose-limiting toxicity, simplifying production, and fasting the availability of the repositioned drug.\n\nID: 40662763\nTitle: Class and isotype of VlsE-specific antibody differentiates Lyme disease stage.\nAbstract: Establishment of immunoglobulin diversity is contingent on recombination that occurs both at the Fab and at the Fc regions of the immunoglobulin, and this process is time dependent. Based on this principle, we questioned whether Lyme disease stage can be distinguished by quantification of immunoglobulin class and IgG isotype specific to VlsE in serum from clinically characterized patients. We used an enzyme immunoassay to categorize serologic antibodies to VlsE antigen as well as machine-learning techniques to train and integrate multiple predictors to identify likely disease stage. We found that IgM/IgG3/IgG1/IgA1 was enriched in serum obtained in the earliest stages, whereas IgG3/IgG1/IgG4 was enriched in Lyme arthritis. IgG2 detection was unremarkable across all disease stages. Post-Treatment Lyme Disease Syndrome (PTLDS) serum was enriched in IgG3/IgG1/IgA1 but lacked IgM. The multivariable models showed better predictive accuracy than any single immunoglobulin model, with more than half of panels perfectly identified by random forest under cross validation (56%) vs a maximum of 38% for a model using IgG1 alone. The findings suggest a characteristic succession of VlsE-specific antibody switching between immunoglobulin class and IgG isotype as Lyme disease progresses from early to late stages. The data also suggest that immunoglobulin class and IgG isotyping are likely more helpful to distinguish early Lyme disease cases. Comprehensive evaluation of immunoglobulin class (M, G, A) and IgG isotypes (1/2/3/4) provides time-dependent pathogen-induced host response information to current Lyme disease antibody detection and may be useful for differentiation of disease stage. The order of switching between the immunoglobulin heavy chain (Fc) is time dependent, progressing from IgM/D to IgG3/IgG1/IgA1/IgG2/IgG4 and later to IgE/IgA2. In this study, we show that B. burgdorferi-VlsE-specific antibody switching proceeds in a predictable sequence between class (Ig M/G/A) and IgG isotype (IgG 1/2/3/4) as Lyme disease progresses from early to late stage and that antibody class and isotype may be more helpful to distinguish the early stages of Lyme disease. This study advances our understanding of the tempo and structure of the humoral immune response to B. burgdorferi and is applicable to the development of new diagnostic assays for Lyme disease.\n\nID: 40511782\nTitle: Cycles of (Dis)engagement: A Qualitative Meta-Synthesis of the (Health)Care-Seeking Experiences of Patients with Chronic Symptoms Following Lyme Disease.\nAbstract: (Chronic) Lyme disease/post-treatment Lyme disease syndrome ([C]LD/PTLDS) is a post-infection illness that remains contested, resulting in a divergent epistemological landscape (i.e., biomedicine versus alternative medicine). Consequently, (C)LD/PTLDS patients exhaust their (health)care options in their search for symptom relief, falling into cycles of starting and stopping (health)care-seeking. This meta-synthesis reviewed 13 qualitative interview studies representing the (health)care-seeking experiences of 216 (C)LD/PTLDS patients across five countries (i.e., United States, Canada, Netherlands, Australia, France) to examine how communication catalyzes patients' (health)care-seeking behaviors. This study proposes a model of (health)care (dis)engagement, identifying communication as a motor moving patients through (health)care-seeking both within and outside of biomedical models of care. This model extends our understanding of communicative (dis)enfranchisement processes and understandings of why patients disengage and reengage in healthcare-seeking behaviors. Theoretical and practical implications and future directions are discussed.\n\nID: 40385877\nTitle: Prevalence of Rheumatoid Factor and Anti-citrullinated Protein Antibodies in Patients With Post-treatment Lyme Disease.\nAbstract: Post-treatment Lyme disease (PTLD) occurs in a portion of patients\u00a0after initial antibiotic treatment of Lyme disease (LD) and is often characterized by arthralgia without synovitis. Rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) are often used to assess joint pain in this setting; however, their clinical utility remains unknown. Our objective was to define the frequency of these autoantibodies in a large cohort of carefully characterized patients with PTLD meeting a research case definition and to determine the clinical implications of these tests.\u00a0RF and ACPA were tested as indicated clinically and abstracted by chart review. The prevalence of antibodies and their relationship to symptoms were examined. Of the 167 patients included in the analysis, RF status was documented at least once for 78.4% (131 of 167), and ACPA status was available at least once for 88.0% (147 of 167). RF was positive in 3.8% (five of 131), and ACPA was positive in 4.8% (seven of 147)\u00a0at least at one time point.\u00a0A total of 7.2% (12 of 167)\u00a0patients were found to have a positive RF or ACPA test at least at one time point.\u00a0There was no difference in the proportion of patients with RF and/or ACPA based on the initial presenting manifestations of their LD, nor the symptoms of PTLD at later evaluation; however, the small sample size may limit our ability to detect these clinical differences. We found a low prevalence of RF and ACPA in this study, similar to the known rates in the general population. This reflects the lack of inflammatory arthritis in this population with clinically defined PTLD and arthralgia only.\n\nID: 39994562\nTitle: A comparison of genome-wide association analyses of persistent symptoms after Lyme disease, fibromyalgia, and myalgic encephalomyelitis - chronic fatigue syndrome.\nAbstract: Up to 20% of Lyme disease cases experience post-treatment Lyme disease syndrome (PTLDS). The biological basis for PTLDS is poorly understood and no evidence-based treatment has been identified. Genetic studies have the potential to elucidate PTLDS pathophysiology and identify treatment targets. We used electronic health record data (EHR) and genetic data from a linked biorepository to conduct a genome-wide association study (GWAS) for PTLDS among patients from a Pennsylvania health system. We evaluated the validity of the GWAS results in two separate conditions that have hypothesized overlapping pathophysiology, fibromyalgia and myalgic encephalomyelitis - chronic fatigue syndrome (ME/CFS). GWAS analyses were performed using logistic regression in SUGEN, assuming an additive genetic model, and adjusting for age, sex, array, and the first 10 principal components calculated from whole genome genotyping to adjust for ancestry, and accounting for relatedness including all 1st degree relationships. The functional mapping and annotation analysis (FUMA) tool was used to explore top findings from our GWAS. Among the 161,875 eligible MyCode participants with genotyping, there were 3,585 who met the criteria for treated Lyme disease. A subset of 695 (19.4%) of these patients met the criteria for PTLDS and the remaining 2890 were classified as controls. We identified two PTLDS loci that reached the suggestive significance threshold (P\u2009<\u20095\u2009\u00d7\u200910-\u20097), with lead variants rs77857587, near IRX1, and rs10833979, near GAS2. Our top index single nucleotide polymorphism (SNP), rs77857587, is in high linkage disequilibrium with a long-range protein quantitative locus SNP, rs111774530, for the MARC2 (Mitochondrial Amidoxime Reducing Component 2) protein. We identified 5,041 cases of fibromyalgia (150,599 controls) and 2,268 cases of ME/CFS (151,594 controls) among the MyCode participants. Neither of the two suggestively significant loci were associated with fibromyalgia or ME/CFS. We identified two PTLDS loci that reached a suggestive significance threshold. Our top index SNP is associated with the MARC2 protein, a protein that has been linked to multiple immune checkpoints. Further study is needed in a larger population to evaluate whether there is genetic evidence of the role of immune response in the occurrence of PTLDS.\n\nID: 39770289\nTitle: Examining Infant and Child Neurodevelopmental Outcomes After Lyme Disease During Pregnancy.\nAbstract: Lyme disease is the most common vector-borne disease in the United States. Recent environmental and socioecological changes have led to an increased incidence of Lyme and other tick-borne diseases, which enhances the urgency of identifying and mitigating adverse outcomes of Lyme disease exposure. Lyme disease during pregnancy, especially when untreated, may lead to adverse pregnancy and neonatal outcomes; however, long-term child outcomes following utero exposure to Lyme disease have not yet been systematically assessed. This concise review describes the current state of knowledge of Lyme disease as a congenital infection and the potential effects of in utero exposure to Lyme disease infection on the neurodevelopment of infants and children. We highlight the importance of distinguishing between acute Lyme disease and a chronic condition termed Post-Treatment Lyme Disease Syndrome, as the impacts of both conditions on the developing fetus and subsequent child development may differ. The importance of placental pathology for patients with acute or chronic symptoms of Lyme disease in pregnancy is explored. Future research aiming to understand and protect neurodevelopment after antenatal Lyme disease must carefully collect potentially confounding variables such as symptomatology and treatment, use clear and standard case definitions, and follow children into school-age and beyond.\n\nID: 39581806\nTitle: Neuroborreliosis at the region of Asturias, Spain (2009-2022): Analysis of 38 cases.\nAbstract: Diagnosis of neurological involvement in Lyme disease is based on two-step serological testing and cerebrospinal fluid pleocytosis. In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients. The most frequent neurological syndromes were radiculoneuritis (36.84%), bilateral facial palsy (13.56%), radiculoneuritis and bilateral facial palsy (10.52%) and multiple cranial mononeuropathy (10.52%), among others. 78.9% achieved a complete recovery, and 15.79% developed post-treatment Lyme disease syndrome. Despite the high incidence of Lyme disease in Asturias, the cases based on hospital admission that can be classified as active disease are lower than those published based on hospital coding. The main source of diagnostic error is positive serological results, without other clinical context, especially in patients studied for cognitive impairment or encephalopathy.\n\nID: 39345262\nTitle: Current and emerging approaches for eliminating Borrelia burgdorferi and alleviating persistent Lyme disease symptoms.\nAbstract: Lyme disease is the most prevalent tick-borne infection caused by Borrelia burgdorferi bacteria in North America. Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated \u223c10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection.\n\nID: 39199993\nTitle: Biomarker-Based Analysis of Pain in Patients with Tick-Borne Infections before and after Antibiotic Treatment.\nAbstract: Tick-borne illnesses (TBIs), especially those caused by Borrelia, are increasingly prevalent worldwide. These diseases progress through stages of initial localization, early spread, and late dissemination. The final stage often leads to post-treatment Lyme disease syndrome (PTLDS) or chronic Lyme disease (CLD), characterized by persistent and non-specific multisystem symptoms affecting multiple systems, lasting over six months after antibiotic therapy. PTLDS significantly reduces functional ability, with 82-96% of patients experiencing pain, including arthritis, arthralgia, and myalgia. Inflammatory markers like CRP and TNF-alpha indicate ongoing inflammation, but the link between chronic pain and other biomarkers is underexplored. This study examined the relationship between pain and biomarkers in TBI patients from an Irish hospital and their response to antibiotic treatment. Pain ratings significantly decreased after antibiotic treatment, with median pain scores dropping from 7 to 5 (U = 27215.50, p < 0.001). This suggests a persistent infection responsive to antibiotics. Age and gender did not influence pain ratings before and after treatment. The study found correlations between pain ratings and biomarkers such as transferrin, CD4%, platelets, and neutrophils. However, variations in these biomarkers did not significantly predict pain changes when considering biomarkers outside the study. These findings imply that included biomarkers do not directly predict pain changes, possibly indicating allostatic load in symptom variability among long-term TBI patients. The study emphasizes the need for appropriate antibiotic treatment for TBIs, highlighting human rights issues related to withholding pain relief.\n\nID: 39161484\nTitle: What Makes It Tick: Exploring the Mechanisms of Post-treatment Lyme Disease Syndrome.\nAbstract: Post-treatment Lyme disease syndrome (PTLDS), which may also be referred to incorrectly as \"chronic Lyme disease,\" is defined by the Infectious Diseases Society of America (IDSA) as the presence of fatigue, pain, and/or cognitive complaints with the functional impact that persists for more than six months after completing treatment for Lyme disease (LD). These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues.\n\nID: 38965869\nTitle: Retrograde and semantic amnesia in a case of post-treatment Lyme disease syndrome: did something lead to a psychogenic memory loss? A single-case study.\nAbstract: To describe a case of Post-Treatment Lyme Disease Syndrome (PTLDS) with an atypical cognitive profile. A 41-year-old PTLDS patient underwent comprehensive neuropsychological testing and psychological assessment. The patient exhibited impaired intensive attention but preserved selective attention. Executive functions were normal. Short-term and anterograde memory were intact, while retrograde and semantic memory were significantly impaired. The patient also experienced identity loss, specific phobias, dissociative symptoms, and depressed mood. Severe episodic-autobiographical and retrograde semantic amnesia was consistent with some reports of dissociative amnesia. Loss of identity and phobias were also highly suggestive of a psychogenic mechanism underlying amnesia.\n\nID: 38792737\nTitle: Combining Double-Dose and High-Dose Pulsed Dapsone Combination Therapy for Chronic Lyme Disease/Post-Treatment Lyme Disease Syndrome and Co-Infections, Including Bartonella: A Report of 3 Cases and a Literature Review.\nAbstract: Three patients with relapsing and remitting borreliosis, babesiosis, and bartonellosis, despite extended anti-infective therapy, were prescribed double-dose dapsone combination therapy (DDDCT) for 8 weeks, followed by one or several two-week courses of pulsed high-dose dapsone combination therapy (HDDCT). We discuss these patients' cases to illustrate three important variables required for long-term remission. First, diagnosing and treating active co-infections, including Babesia and Bartonella were important. Babesia required rotations of multiple anti-malarial drug combinations and herbal therapies, and Bartonella required one or several 6-day HDDCT pulses to achieve clinical remission. Second, all prior oral, intramuscular (IM), and/or intravenous (IV) antibiotics used for chronic Lyme disease (CLD)/post-treatment Lyme disease syndrome (PTLDS), irrespective of the length of administration, were inferior in efficacy to short-term pulsed biofilm/persister drug combination therapy i.e., dapsone, rifampin, methylene blue, and pyrazinamide, which improved resistant fatigue, pain, headaches, insomnia, and neuropsychiatric symptoms. Lastly, addressing multiple factors on the 16-point multiple systemic infectious disease syndrome (MSIDS) model was important in achieving remission. In conclusion, DDDCT with one or several 6-7-day pulses of HDDCT, while addressing abnormalities on the 16-point MSIDS map, could represent a novel effective clinical and anti-infective strategy in CLD/PTLDS and associated co-infections including Bartonella.\n\nID: 38752040\nTitle: Neuropsychiatric Manifestations and Cognitive Decline in Patients With Long-Standing Lyme Disease: A Scoping Review.\nAbstract: Lyme disease (LD), or Lyme borreliosis, is a vector-borne disease that is caused by the transmission of the bacterium Borrelia burgdorferi through a tick bite. The symptoms of LD can persist in individuals chronically, even after the treatment and resolution of the initial infection. These symptoms include various neuropsychiatric manifestations and cognitive decline. The purpose of this review was to report the neuropsychiatric manifestations, cognitive decline, and effects of a delayed diagnosis on symptom severity in patients with long-standing LD (LSLD). A scoping review was conducted utilizing the electronic databases Embase, Ovid Medical Literature Analysis and Retrieval System Online (MEDLINE), and Web of Science. A total of 744 articles were retrieved and considered for inclusion. After a rigorous screening process, 10 articles that met the inclusion criteria for this review were included (i.e., reported neuropsychiatric manifestations and cognitive decline in patients with LSLD and the effects of a delayed diagnosis). Neuropsychiatric manifestations in the patients consisted of suicidal ideation, homicidal tendencies, extreme anger, depressive symptoms, aggression, and anxiety. Cognitive symptoms included dysfunctions in working memory, verbal learning/memory, non-verbal learning/memory, alertness, visuoconstructive, and frontal executive functioning. A delayed LD diagnosis increased symptom severity in most patients. The findings of this review indicate that neuropsychiatric and cognitive symptoms tend to present for a chronic period, even after disease recovery. Although researchers have established a link between a delayed LD diagnosis and increased symptom severity, LSLD is often an overlooked diagnosis in patients with neuropsychiatric symptoms and cognitive decline. More research is needed to compare the time to diagnosis and symptom severity in patients with LSLD.\n\nID: 38613155\nTitle: A prospective study of patients with post treatment Lyme disease syndrome treated with modified VFEM energy.\nAbstract: We previously demonstrated a possible therapeutic benefit of VFEM (variable frequency electromagnetic energy) technology for the treatment of Post Treatment Lyme Disease Syndrome (PTLDS) or Chronic Lyme Disease (CLD). As a result, we prospectively enrolled 10 patients, all having significant debility, to determine to what extent we could improve their quality of life. Eight patients completed the 10 treatments. All eight patients had a significant improvement in quality of life within a 4-month time frame. VFEM is a stand-alone modality that appears to demonstrate a significant improvement in quality of life in PTLDS or CLD with little or no risk or side effects of treatment.\n\nID: 40265182\nTitle: A pilot study of disulfiram for individuals with persistent symptoms despite prior antibiotic treatment for Lyme disease.\nAbstract: In vitro studies report that disulfiram is effective in killing Borrelia burgdorferi. Case series suggest disulfiram may help to reduce the symptoms of patients with persistent symptoms despite prior antibiotic treatment for Lyme disease. This pilot study assessed safety, tolerability, and signs of clinical response. Participants with a history of previously treated Lyme disease and persistent fatigue were randomly assigned in a double-blinded fashion to either Group A (disulfiram for 4 weeks and placebo for 4 weeks) or Group B (disulfiram for 8 weeks). Primary outcome endpoint was at 10 weeks with a follow-up at 14 weeks. The primary aim was to assess safety and tolerability. A clinical aim assessed signs of clinical improvement using well-validated measures, focusing on improvement in fatigue and quality of life. Target enrollment was 24 participants. 940 individuals were screened, 11 were enrolled and nine participated in the trial. Dosing started low and increased based on response and tolerance to a maximum of 500 mg daily. Safety. Two participants discontinued medication due to clinical worsening, one of whom was briefly hospitalized. Three additional participants were withdrawn from treatment due to lab test abnormalities. Tolerability. Only three of nine participants completed the full course of treatment (two in Group A and one in Group B). Lower doses were better tolerated than the highest dose. Clinical response. Of nine participants, clinically meaningful improvement was noted in fatigue for six and in quality of life for four. Among the six fatigue responders, improvement was also noted on a multiple domain symptom index (six of six), overall symptom burden (five of six), and functional impairment (four of six). The study was terminated early due to end of project funding, higher than expected adverse events, and recognition that sufficient information was gathered to inform future studies. This study reveals the risks associated with disulfiram, especially at higher doses, while suggesting potential clinical benefits among some participants. Efficacy could not be assessed given the small sample size and the lack of a placebo-control group. https://clinicaltrials.gov/study/NCT03891667?cond=Lyme%20Disease&intr=disulfiram&rank=1, NCT03891667.\n\nID: 37784031\nTitle: Diagnosis and treatment of \"chronic Lyme\": primum non nocere.\nAbstract: Approximately 10% of patients experience prolonged symptoms after Lyme disease. PTLDS (post treatment Lyme disease syndrome) is a controversial topic. It has been described as a source of overdiagnosis and off-label treatment. This review aims to describe the diagnostic errors and adverse events associated with the diagnosis and treatment of PTLDS. systematic review of the literature in the Medline and Cochrane Library databases, according to PRISMA criteria, including randomized clinical trials (RCT), observational studies, and case reports addressing diagnostic errors and adverse events published between January 2010 and November 2020 in English or French. Selection used a quadruple reading process on the basis of the titles and abstracts of the different articles, followed by a full reading. 17 studies were included: 1 RCT, 6 observational studies and 10 case reports. In the 6 observational studies, overdiagnosis rates were very high, ranging from 80 to 100%. The new diagnoses were often psychiatric, rheumatological and neurological. Disorders with somatic symptoms were often cited. Diagnostic delays were identified for cancers and frontoparietal dementia. In the RCT and observational studies, prolonged anti-infective treatments were also responsible for adverse events, with emergency room visits and/or hospitalization. The most common adverse events were diarrhea, sometimes with Clostridium difficile colitis, electrolyte abnormalities, sepsis, bacterial and fungal infections, and anaphylactic reactions. This review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS. It emphasizes the ethical imperative of the \"primum non nocere\" principle, which underscores the importance of not causing harm to patients. Physicians should exercise caution in diagnosing PTLDS and consider the potential risks associated with off-label treatments.\n\nID: 36836887\nTitle: Myositis Autoantibodies in Patients with Suspected Post-Treatment Lyme Disease Syndrome.\nAbstract: Most patients suffering from Lyme disease are effectively treated with antibiotics. In some patients, however, problems persist for a long time despite appropriate therapy. The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients. The study detected raised MSA/MAA autoantibodies formation in the group of PTLDS patients raising the question about their involvement in the pathogenesis of this syndrome.\n\nID: 34835343\nTitle: Seroprevalence of Antibodies against Tick-Borne Pathogens in Czech Patients with Suspected Post-Treatment Lyme Disease Syndrome.\nAbstract: The hypothesized importance of coinfections in the pathogenesis of post-treatment Lyme disease syndrome (PTLDS) leads to the use of combined, ongoing antimicrobial treatment in many cases despite the absence of symptoms typical of the presence of infection with specific pathogens. Serum samples from 103 patients with suspected post-treatment Lyme disease syndrome were tested for the presence of antibodies to the major tick-borne pathogens Anaplasma phagocytophilum, Bartonella henselae/Bartonella quinatana, and Babesia microti. Although the presence of anti-Anaplasma antibodies was detected in 12.6% of the samples and anti-Bartonella antibodies in 9.7% of the samples, the presence of antibodies against both pathogens in the same samples or anti-Babesia antibodies in the selected group of patients could not be confirmed. However, we were able to detect autoantibodies, mostly antinuclear, in 11.6% of the patients studied. Our results are in good agreement with previously published studies showing the presence of a wide spectrum of autoantibodies in some patients with complicated forms of Lyme disease and post-treatment Lyme disease syndrome, but they do not reveal a significant influence of co-infections on the development of PTLDS in the studied group of patients.\n\nID: 31888310\nTitle: Chronic Lyme Disease: An Evidence-Based Definition by the ILADS Working Group.\nAbstract: Objective: Chronic Lyme disease has been a poorly defined term and often dismissed as a fictitious entity. In this paper, the International Lyme and Associated Diseases Society (ILADS) provides its evidence-based definition of chronic Lyme disease. Definition: ILADS defines chronic Lyme disease (CLD) as a multisystem illness with a wide range of symptoms and/or signs that are either continuously or intermittently present for a minimum of six months. The illness is the result of an active and ongoing infection by any of several pathogenic members of the Borrelia burgdorferi sensu lato complex (Bbsl). The infection has variable latency periods and signs and symptoms may wax, wane and migrate. CLD has two subcategories, CLD, untreated (CLD-U) and CLD, previously treated (CLD-PT). The latter requires that CLD manifestations persist or recur following treatment and are present continuously or in a relapsing/remitting pattern for a duration of six months or more. Methods: Systematic review of over 250 peer reviewed papers in the international literature to characterize the clinical spectrum of CLD-U and CLD-PT. Conclusion: This evidence-based definition of chronic Lyme disease clarifies the term's meaning and the literature review validates that chronic and ongoing Bbsl infections can result in chronic disease. Use of this CLD definition will promote a better understanding of the infection and facilitate future research of this infection.\n\nID: 30946803\nTitle: Stationary phase persister/biofilm microcolony of Borrelia burgdorferi causes more severe disease in a mouse model of Lyme arthritis: implications for understanding persistence, Post-treatment Lyme Disease Syndrome (PTLDS), and treatment failure.\nAbstract: Although most patients with Lyme disease can be cured with a 2-4 week antibiotic therapy, about 10-20% of patients continue to suffer prolonged persistent symptoms, a condition called post-treatment Lyme disease syndrome (PTLDS). The cause for PTLDS is unclear and hotly debated. Borrelia burgdorferi develops morphological variants under stress conditions but their significance is not clear. Here we isolated the biofilm-like microcolony (MC) and planktonic (spirochetal form and round body) (SP) variant forms from the stationary phase culture of B. burgdorferi and showed that the MC and SP variant forms were not only more tolerant to the current Lyme antibiotics but also caused more severe arthritis in mice than the log phase spirochete form (LOG). We propose to divide the persistent Lyme disease into two categories: (1) early development of persistent disease from inoculation with persister/biofilm at the beginning of infection introduced by tick bites, or Type I persistent disease (i.e., PTLDS); and (2) late development of persistent disease due to initial infection not being diagnosed or treated in time such that the infection develops into late persistent disease, or Type II persistent disease. Importantly, we show that the murine infection caused by LOG could be eradicated by ceftriaxone whereas the persistent infection established with MC could not be eradicated by doxycycline (Doxy), ceftriaxone (CefT), or vancomycin (Van), or Doxy+CefT or Van+CefT, but could only be eradicated by the persister drug combination daptomycin+doxycycline+ceftriaxone. We conclude that varying levels of persistence and pathologies of Borrelia infection and the corresponding different treatment responses are mostly dictated by the heterogeneous B. burgdorferi variant forms inoculated at the time of tick bites. These findings may have broad implications for understanding pathogenesis and treatment of not only persistent Lyme disease but also other persistent infections in general and call for studies to evaluate if treatment of persistent infections with persister drug combination regimens is more effective than the current mostly single-antibiotic monotherapy.\n\nID: 30736992\nTitle: Functional neuroimaging in patients presenting with somatoform disorders: A model for investigating persisting symptoms after tick bites and post-treatment Lyme disease syndrome?\nAbstract: Approximately 10% of patients presenting with Lyme disease experience fatigue, musculoskeletal pain, concentration disorders, or short-term memory deficits in the six months following treatment. This entity has been defined as post-Lyme disease syndrome or post-treatment Lyme disease syndrome. The pathophysiology of this syndrome is unknown, but neither persistence of the bacterium nor effectiveness of antibiotics are currently reported in the literature. The French High Council for Public Health (French acronym HCSP) has recently defined a new entity called \"persistent polymorphic symptoms after a tick bite\" allowing for designing studies to better understand these subjective presentations, for which objective biomarkers are currently lacking. This entity encompasses patients experiencing fatigue and generalized pain in the months following a tick bite and can be associated with several subjective symptoms with major impact on the quality of life. In the field of somatoform disorders, this article reviews functional neuroimaging studies in patients presenting with subjective complaints and discusses potential clinical implications for persisting symptoms after tick bites and post-treatment Lyme disease syndrome.\n\nID: 27000820\nTitle: [Post-Lyme disease syndrome].\nAbstract: Lyme disease is a chronic infectious disease caused by the bacteria, spirochete of the Borrelia type. Skin, nervous system, musculoskeletal system and heart may be involved in the course of the disease. The prognosis for properly treated Lyme disease is usually good. However, in about 5% of patients so called Post-Lyme disease syndrome (PLSD) develops. It is defined as a syndrome of subjective symptoms persisting despite proper treatment of Borrelia burgdorferi infection. The most common symptoms include: fatigue, muscle and joint pain, and problems with memory and concentration. Pathogenesis of PLDS remains unknown. The differential diagnosis should include neurological, rheumatic and mental diseases. Till now there is no causative treatment of PLDS. In relieving symptom rehabilitation, painkillers, anti-inflammatory and antidepressants medicines are recommended. Emotional and psychological supports are also necessary. Non-specific symptoms reported by patients with post- Lyme disease syndrome raise the suspicion of other pathologies. This can lead to misdiagnosis and implementation of unnecessary, potentially harmful to the patient's therapy. An increase in tick-borne diseases needs to increase physicians awareness of these issues.\n\nID: 25806811\nTitle: Drug combinations against Borrelia burgdorferi persisters in vitro: eradication achieved by using daptomycin, cefoperazone and doxycycline.\nAbstract: Although most Lyme disease patients can be cured with antibiotics doxycycline or amoxicillin using 2-4 week treatment durations, some patients suffer from persistent arthritis or post-treatment Lyme disease syndrome. Why these phenomena occur is unclear, but possibilities include host responses, antigenic debris, or B. burgdorferi organisms remaining despite antibiotic therapy. In vitro, B. burgdorferi developed increasing antibiotic tolerance as morphology changed from typical spirochetal form in log phase growth to variant round body and microcolony forms in stationary phase. B. burgdorferi appeared to have higher persister frequencies than E. coli as a control as measured by SYBR Green I/propidium iodide (PI) viability stain and microscope counting. To more effectively eradicate the different persister forms tolerant to doxycycline or amoxicillin, drug combinations were studied using previously identified drugs from an FDA-approved drug library with high activity against such persisters. Using a SYBR Green/PI viability assay, daptomycin-containing drug combinations were the most effective. Of studied drugs, daptomycin was the common element in the most active regimens when combined with doxycycline plus either beta-lactams (cefoperazone or carbenicillin) or an energy inhibitor (clofazimine). Daptomycin plus doxycycline and cefoperazone eradicated the most resistant microcolony form of B. burgdorferi persisters and did not yield viable spirochetes upon subculturing, suggesting durable killing that was not achieved by any other two or three drug combinations. These findings may have implications for improved treatment of Lyme disease, if persistent organisms or detritus are responsible for symptoms that do not resolve with conventional therapy. Further studies are needed to validate whether such combination antimicrobial approaches are useful in animal models and human infection.\n\nID: 25506429\nTitle: Relevance of chronic lyme disease to family medicine as a complex multidimensional chronic disease construct: a systematic review.\nAbstract: Lyme disease has become a global public health problem and a prototype of an emerging infection. Both treatment-refractory infection and symptoms that are related to Borrelia burgdorferi infection remain subject to controversy. Because of the absence of solid evidence on prevalence, causes, diagnostic criteria, tools and treatment options, the role of autoimmunity to residual or persisting antigens, and the role of a toxin or other bacterial-associated products that are responsible for the symptoms and signs, chronic Lyme disease (CLD) remains a relatively poorly understood chronic disease construct. The role and performance of family medicine in the detection, integrative treatment, and follow-up of CLD are not well studied either. The purpose of this paper is to describe insights into the complexity of CLD as a multidimensional chronic disease construct and its relevance to family medicine by means of a systematic literature review.\n\nID: 25318999\nTitle: Persistent Lyme Empiric Antibiotic Study Europe (PLEASE)--design of a randomized controlled trial of prolonged antibiotic treatment in patients with persistent symptoms attributed to Lyme borreliosis.\nAbstract: Lyme borreliosis, a potentially severe tick-borne infection caused by Borrelia burgdorferi, can cause multi-system inflammatory disease. The incidence has been increasing, as has the number of patients with persistent symptoms attributed to Borrelia. These symptoms, also referred to as post-Lyme disease syndrome, may follow an erythema migrans or other Lyme manifestations, and include pain, fatigue, and cognitive disturbances. The optimal duration of treatment for these symptoms is a subject of controversy. The PLEASE study is designed to determine whether prolonged antibiotic treatment leads to better patient outcome than standard treatment. The PLEASE study is a double-blind, randomized, placebo-controlled trial. Based on power analysis and compensating for possible loss to follow-up, a minimum of 255 patients with borreliosis-attributed persistent symptoms are included. These symptoms are either (a) temporally related to an erythema migrans or otherwise proven symptomatic borreliosis, or (b) accompanied by a positive B. burgdorferi IgG or IgM immunoblot. All patients receive open-label ceftriaxone for two weeks. Patients are then randomized (ratio 1:1:1) to blinded oral follow-up treatment for 12 weeks with (I) doxycycline, (II) clarithromycin combined with hydroxychloroquine, or (III) placebo. The primary outcome is the physical component summary score (PCS) of the RAND-36 Health Status Inventory (RAND SF-36) at week 14. Secondary outcomes include physical and mental aspects of health-related quality of life (assessed by the subscales of the RAND SF-36), fatigue, neuropsychological evaluation, physical activity, and cost-effectiveness. This article describes the background and design issues of the PLEASE study protocol. The results of this study may provide evidence for prescribing or withholding prolonged antibiotic treatment.

Many such patients also are treated for chronic coinfections with Babesia, Anaplasma, or Bartonella in the absence of typical presentations, objective clinical findings, or laboratory confirmation of active infection. We have undertaken a systematic review of the literature to evaluate several aspects of this practice. Five systematic literature searches were performed using Boolean operators and the PubMed search engine. The literature searches did not demonstrate convincing evidence of: 1) chronic anaplasmosis infection; 2) treatment-responsive symptomatic chronic babesiosis in immunocompetent persons in the absence of fever, laboratory abnormalities, and detectable parasitemia; 3) either geographically widespread or treatment-responsive symptomatic chronic infection with Babesia duncani in the absence of fever, laboratory abnormalities, and detectable parasitemia; 4) tick-borne transmission of Bartonella species; or 5) simultaneous Lyme disease and Bartonella infection. The medical literature does not support the diagnosis of chronic, atypical tick-borne coinfections in patients with chronic, nonspecific illnesses.\n\nID: 24336823\nTitle: A systematic review of Borrelia burgdorferi morphologic variants does not support a role in chronic Lyme disease.\nAbstract: \u2003Much of the controversy that surrounds Lyme disease pertains to whether it produces prolonged, treatment-refractory infection, usually referred to as chronic Lyme disease. Some have proposed that round morphologic variants of Borrelia burgdorferi, known variably as \"cyst forms\" and \"L-forms,\" are responsible for the pathogenesis of chronic Lyme disease. We have undertaken a systematic review of the literature to determine if there is a documented role of these variants in Lyme disease pathogenesis or in syndromes compatible with chronic Lyme disease. \u2003Two systematic literature searches were performed to identify studies in which round morphologic variants of B. burgdorferi have been described in situ in human specimens. \u2003Our primary literature search identified 6 studies that reported round morphologic variants of B. burgdorferi in specimens obtained from 32 total patients. No study described these forms in patients who had purely subjective symptom complexes (eg, fatigue or pain). No study investigated a causal relationship between morphologic variants and clinical disease or evaluated treatment of morphologic variants in vivo. Of 29 additional studies that described the morphology of B. burgdorferi from patients with Lyme disease, the organism was invariably described as having spirochetal morphology. \u2003In the context of the broader medical literature, it is not currently possible to ascribe a pathogenic role to morphologic variants of B. burgdorferi in either typical manifestations of Lyme disease or in other chronic disease states that are often labeled chronic Lyme disease. There is no clinical literature to justify specific treatment of B. burgdorferi morphologic variants.\n\nID: 23764268\nTitle: Treatment trials for post-Lyme disease symptoms revisited.\nAbstract: The authors of 4 National Institutes of Health-sponsored antibiotic treatment trials of patients with persistent unexplained symptoms despite previous antibiotic treatment of Lyme disease determined that retreatment provides little if any benefit and carries significant risk. Two groups recently provided an independent reassessment of these trials and concluded that prolonged courses of antibiotics are likely to be helpful. We have carefully considered the points raised by these groups, along with our own critical review of the treatment trials. On the basis of this analysis, the conclusion that there is a meaningful clinical benefit to be gained from retreatment of such patients with parenteral antibiotic therapy cannot be justified.\n\nID: 22962880\nTitle: Diagnosis and management of Lyme disease.\nAbstract: Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common tick-borne illness in the United States. Transmission occurs primarily through the bite of an infected deer tick (Ixodes scapularis). Identification of an erythema migrans rash following a tick bite is the only clinical manifestation sufficient to make the diagnosis of Lyme disease in the absence of laboratory confirmation. The Centers for Disease Control and Prevention recommends a two-tier serologic testing protocol using an enzyme-linked immunosorbent assay initially, followed by the more specific Western blot to confirm the diagnosis when the assay samples are positive or equivocal. The treatment of Lyme disease is determined mainly by the clinical manifestations of the disease. Doxycycline is often the preferred agent for oral treatment because of its activity against other tick-borne illnesses. Preventive measures include avoiding areas with high tick burdens, wearing protective clothing, using tick repellants (e.g., diethyltoluamide [DEET]), performing frequent body checks and bathing following outdoor activities, and instituting environmental landscape modifications (e.g., grass mowing, deer exclusion fencing) to reduce the tick burden. Although there is controversy regarding treatment of post-Lyme disease syndrome and chronic Lyme disease, there is no biologic or clinical trial evidence indicating that prolonged antibiotic therapy is of benefit.\n\nID: 22416947\nTitle: The phenomenon of 'chronic Lyme'; an observational study.\nAbstract: To chart clinical, laboratory, and psychometric profiles in patients who attribute their complaints to chronic Lyme disease. We assessed the patients by clinical examination, laboratory tests, and questionnaires measuring fatigue, depression, anxiety, health-related quality of life, hypochondriasis, and illness perceptions. We found no evidence of ongoing Borrelia burgdorferi (Bb) infection in any of the 29 included patients using current diagnostic guidelines and an extended array of tests. Eight (28%) had other well-defined illnesses. Twenty-one (72%) had symptoms of unknown cause, of those six met the suggested criteria for post-Lyme disease syndrome. Fourteen (48%) had presence of anti-Bb antibodies. The patients had more fatigue and poorer health-related quality of life as compared to normative data, but were not more depressed, anxious, or hypochondriacal. Their beliefs about the illness were characterized by negative expectations. Our patients, who all attributed their symptoms to chronic Lyme disease, were heterogeneous. None had evidences of persistent Bb infection, but whether current diagnostic criteria are functional in patients with longstanding complaints is controversial. Other well-defined illnesses or sequelae from earlier Lyme disease were probable as main explanatory factor in some cases. The patients were not more depressed, anxious, or hypochondriacal than the normal population, but they had poorer health-related quality of life, more fatigue, and negative expectations about their illness.\n\nID: 21810051\nTitle: Chronic Lyme disease: the controversies and the science.\nAbstract: The diagnosis of chronic Lyme disease has been embroiled in controversy for many years. This is exacerbated by the lack of a clinical or microbiologic definition, and the commonality of chronic symptoms in the general population. An accumulating body of evidence suggests that Lyme disease is the appropriate diagnosis for only a minority of patients in whom it is suspected. In prospective studies of Lyme disease, very few patients go on to have a chronic syndrome dominated by subjective complaints. There is no systematic evidence that Borrelia burgdorferi, the etiology of Lyme disease, can be identified in patients with chronic symptoms following treated Lyme disease. Multiple prospective trials have revealed that prolonged courses of antibiotics neither prevent nor alleviate such post-Lyme syndromes. Extended courses of intravenous antibiotics have resulted in severe adverse events, which in light of their lack of efficacy, make them contraindicated.\n\nID: 19910896\nTitle: Obstacles to trials of chronic Lyme disease in actual practice.\nAbstract: \n\nID: 19597005\nTitle: Antibiotic treatment of animals infected with Borrelia burgdorferi.\nAbstract: Despite resolution of the objective manifestations of Lyme disease after antibiotic treatment, a minority of patients have fatigue, musculoskeletal pain, and/or difficulties with concentration or short-term memory of uncertain etiology; these are called post-Lyme disease symptoms or, in more severe cases, post-Lyme disease syndrome or \"chronic Lyme disease.\" Several recent studies in which Borrelia burgdorferi-infected animals were treated with antibiotic therapy have demonstrated the presence of PCR positivity for B. burgdorferi DNA in the absence of culture positivity. In mice that were treated with antibiotic therapy, residual spirochetes could be taken up by ticks during a blood meal and could be transmitted to SCID mice. These spirochetes are attenuated; their presence is not associated with either inflammation or disease. In this review the methodology and findings of these studies are critically analyzed, and the significance of the results with regard to human Lyme disease is evaluated, with special emphasis on whether these studies provide useful insights into post-Lyme disease syndrome. A serious methodological concern is the failure to consider the pharmacokinetic-pharmacodynamic properties of the antibiotic in choosing the dosage regimen used. We conclude that there is no scientific evidence to support the hypothesis that such spirochetes, should they exist in humans, are the cause of post-Lyme disease syndrome.\n\nID: 19514824\nTitle: Implications of gender in chronic Lyme disease.\nAbstract: \"Post-Lyme disease syndrome\" refers to prolonged subjective symptoms after antibiotic treatment and resolution of an objective manifestation of Borrelia burgdorferi infection (Lyme disease). \"Chronic Lyme disease\" is a vaguely defined term that has been applied to patients with unexplained prolonged subjective symptoms, whether or not there was or is evidence of B. burgdorferi infection. To determine if the population of patients with chronic Lyme disease differs from the populations of patients with either Lyme disease or post-Lyme disease syndrome by examining the gender of patients with these diagnoses. Data on gender were compiled in this cross-sectional study based on a systematic review of published studies of antibiotic treatment in United States patients with post-Lyme disease syndrome (n = 184) or chronic Lyme disease (n = 490), and on cases of adults with Lyme disease reported to the Centers for Disease Control and Prevention from 2003 to 2005 (n = 43,282). Patients with chronic Lyme disease were significantly more likely to be female than were patients diagnosed with either Lyme disease (odds ratio [OR] 2.42, 95% confidence interval [CI] 1.98-2.94, p < 0.0001) or with post-Lyme disease syndrome (OR 2.32, 95% CI 1.62-3.34, p < 0.0001). Patients with chronic Lyme disease differ with regard to gender from those with either B. burgdorferi infection or post-Lyme disease syndrome. This finding suggests that illnesses with a female preponderance, such as fibromyalgia, chronic fatigue syndrome, or depression, may be misdiagnosed as chronic Lyme disease.\n\nID: 19268485\nTitle: Insufficient evidence to deny antibiotic treatment to chronic Lyme disease patients.\nAbstract: The severity, length of illness, and cost of chronic Lyme disease (CLD) have been well described. A number of oral, intravenous, and intramuscular antibiotics have been prescribed for CLD. Surprisingly few antibiotic schedules prescribed for the treatment of CLD have been evaluated in randomized double-blind placebo-controlled clinical trials (RCTs). Physicians have increasingly turned to clinical treatment guideline (CPG) panels to judge the mixed results of the evidence. Two CPG panels have looked at the evidence only to reach opposite conclusions: (1) antibiotic therapy for CLD is not effective and (2) antibiotic therapy for CLD is effective. Physicians have been advised by guideline developers to use clinical discretion in diagnosing and treating CLD. Nevertheless, many health insurers - relying exclusively upon only one CPG - have a policy of automatically denying antibiotics to CLD patients regardless of the specifics of each case or the recommendations of the patient's physician. This paper examined the eight limitations of the evidence used to conclude that antibiotics therapy for CLD is not effective in forming the following hypothesis: insufficient evidence to deny antibiotic treatment to CLD patients. There are eight limitations that support the hypothesis: (1) the power of the evidence is inadequate to draw definite conclusions, (2) the evidence is too heterogeneous to make strong recommendations, (3) the risk to an individual of facing a long-term debilitating illness has not been considered, (4) the risk to society of a growing chronically ill population has not been considered, (5) treatment delay has not been considered as a confounder, (6) co-infections have not been considered as a confounder, (7) the design of RCTs did not address the range of treatment options in an actual practice, and (8) the findings cannot be generalized to actual practice. This hypothesis suggests that physicians should consider the limitations of the evidence before denying antibiotic treatment for CLD. Physicians who deny antibiotic treatment to CLD patients might inform their patients that there are some clinicians who disagree with that position, and then offer to refer them for a second opinion to a doctor who could potentially present a different point of view. The hypothesis also suggests that health care insurers should consider the limitations of the evidence before adopting policies that routinely deny antibiotic treatment for CLD patients and should expand coverage of CLD to include clinical discretion for specific clinical situations.\n\nID: 18589049\nTitle: Perspectives on \"chronic Lyme disease\".\nAbstract: There is much controversy about the treatment of Lyme disease with respect to 2 poorly defined entities: \"chronic Lyme disease\" and \"posttreatment Lyme disease syndrome.\" In the absence of direct evidence that these conditions are the result of a persistent infection, some mistakenly advocate extended antibiotic therapy (>/=6 months), which can do great harm and has resulted in at least 1 death. The purpose of this brief report is to review what is known from clinical research about these conditions to assist both practicing physicians and lawmakers in making sound and safe decisions with respect to treatment.\n\nID: 18452806\nTitle: Chronic Lyme disease: a review.\nAbstract: Studies have shown that most patients diagnosed with chronic Lyme disease either have no objective evidence of previous or current infection with Borrelia burgdorferi or are patients who should be classified as having post-Lyme disease syndrome, which is defined as continuing or relapsing nonspecific symptoms (such as fatigue, musculoskeletal pain, and cognitive complaints) in a patient previously treated for Lyme disease. Despite extensive study, there is currently no clear evidence that post-Lyme disease syndrome is caused by persistent infection with B burgdorferi. Four randomized placebo-controlled studies have shown that antibiotic therapy offers no sustained benefit to patients who have post-Lyme disease syndrome. These studies also showed a substantial placebo effect and a significant risk of treatment-related adverse events. Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed.\n\nID: 17914043\nTitle: A critical appraisal of \"chronic Lyme disease\".\nAbstract: \n\nID: 12821733\nTitle: Cognitive function in post-treatment Lyme disease: do additional antibiotics help?\nAbstract: It is controversial whether additional antibiotic treatment will improve cognitive function in patients with post-treatment chronic Lyme disease (PTCLD). To determine whether antibiotic therapy improves cognitive function in two randomized double-blind placebo-controlled studies of patients with PTCLD. A total of 129 patients with a physician-documented history of Lyme disease from three study sites in the northeast United States were studied. Seventy-eight were seropositive for IgG antibodies against Borrelia burgdorferi, and 51 were seronegative. Patients in each group were randomly assigned to receive IV ceftriaxone 2 g daily for 30 days followed by oral doxycycline 200 mg daily for 60 days or matching IV and oral placebos. Assessments were made at 90 and 180 days after treatment. Symptom severity was measured from the cognitive functioning, pain, and role functioning scales of the Medical Outcomes Study (MOS). Memory, attention, and executive functioning were assessed using objective tests. Mood was assessed using the Beck Depression Inventory and Minnesota Multiphasic Personality Inventory. There were no significant baseline differences between seropositive and seronegative groups. Both groups reported a high frequency of MOS symptoms, depression, and somatic complaints but had normal baseline neuropsychological test scores. The combined groups showed significant decreases in MOS symptoms, higher objective test scores, and improved mood between baseline and 90 days. However, there were no significant differences between those receiving antibiotics and placebo. Patients with post-treatment chronic Lyme disease who have symptoms but show no evidence of persisting Borrelia infection do not show objective evidence of cognitive impairment. Additional antibiotic therapy was not more beneficial than administering placebo.\n\nID: 12804167\nTitle: Controlled trials of antibiotic treatment in patients with post-treatment chronic Lyme disease.\nAbstract: Some patients have persistence of profound fatigue, myalgias, arthralgias without arthritis, dysesthesia/paresthesia, and mood and memory disturbances after standard courses of antibiotic treatment for Lyme disease. This constellation of symptoms has been variously referred to as \"chronic Lyme disease,\" \"post-Lyme disease syndrome,\" and \"post-treatment chronic Lyme disease.\" Persistent symptoms have been reported in patients who are seropositive for IgG antibodies against Borrelia burgdorferi as well as in patients who are seronegative. The cause or causes of persistent symptoms in these patients have not been clearly defined and are controversial. Because of the temporal association of these symptoms with infection with B. burgdorferi, some patients have been treated with prolonged courses of antibiotics. Case reports and uncontrolled trials have reported the efficacy of prolonged antibiotic therapy, often with relapse of the symptoms after discontinuation of therapy. To date, only one randomized, placebo-controlled, double-blind trial of antibiotic therapy for these patients has been published. An abstract of a second placebo-controlled trial of antibiotic therapy in a smaller cohort has also been presented. This paper will describe this patient population in detail and will review the clinical, microbiological, and selected biochemical and immunologic parameters and their responses to antibiotic treatment in the setting of a controlled trial.\n\nID: 12428915\nTitle: Neuropsychological functioning in chronic Lyme disease.\nAbstract: Lyme disease is currently the most common vector-borne illness in the United States. The disease is multisystemic, and chronic disease, in particular, may be associated with neuropsychological deficits. However, to date, only a few empirical studies exist, which examine the neuropsychological sequelae associated with chronic Lyme disease. A review of the literature shows that the deficits observed in adults with chronic Lyme disease are generally consistent with the deficits that can be seen in processes with primarily frontal systems involvement. These observations are generally consistent with neuroradiologic findings. The clinical presentation in chronic Lyme disease and the nature of the neuropsychological deficits are discussed, as are several central issues in understanding neuropsychological functioning in chronic Lyme disease, such as the impact of chronic illness, response to treatment, and the relationship between neuropsychological performance and depression, fatigue, and neurological indicators of disease.\n\nID: 38075920\nTitle: Superior efficacy of combination antibiotic therapy versus monotherapy in a mouse model of Lyme disease.\nAbstract: Lyme disease (LD) results from the most prevalent tick-borne infection in North America, with over 476,000 estimated cases annually. The disease is caused by Borrelia burgdorferi (Bb) sensu lato which transmits through the bite of Ixodid ticks. Most cases treated soon after infection are resolved by a short course of oral antibiotics. However, 10-20% of patients experience chronic symptoms because of delayed or incomplete treatment, a condition called Post-Treatment Lyme Disease (PTLD). Some Bb persists in PTLD patients after the initial course of antibiotics and an effective treatment to eradicate the persistent Bb is needed. Other organisms that cause persistent infections, such as M. tuberculosis, are cleared using a combination of therapies rather than monotherapy. A group of Food and Drug Administration (FDA)-approved drugs previously shown to be efficacious against Bb in vitro were used in monotherapy or in combination in mice infected with Bb. Different methods of detection were used to assess the efficacy of the treatments in the infected mice including culture, xenodiagnosis, and molecular techniques. None of the monotherapies eradicated persistent Bb. However, 4 dual combinations (doxycycline + ceftriaxone, dapsone + rifampicin, dapsone + clofazimine, doxycycline + cefotaxime) and 3 triple combinations (doxycycline + ceftriaxone+ carbomycin, doxycycline + cefotaxime+ loratadine, dapsone+ rifampicin+ clofazimine) eradicated persistent Bb infections. These results suggest that combination therapy should be investigated in preclinical studies for treating human Lyme disease.\n\nID: 37844086\nTitle: A Multimodal Ayurveda and Mind-Body Therapeutic Intervention for Chronic Symptoms Attributed to a Postinfectious Syndrome: A Pilot Study.\nAbstract: Objective: Evaluate feasibility and impact of a multimodal integrative therapeutic intervention in patients presenting with chronic symptoms attributed to a postinfectious syndrome. Design: This was a prospective longitudinal single-center pilot study conducted from January 2019 to December 2020. Setting/Location: University of Maryland Lyme Program, Baltimore Maryland. Subjects: Persons presenting for Lyme evaluation for symptoms attributed to Lyme disease. Interventions: Participants attended two 1-h individual instructional sessions consisting of Ayurveda-based dietary intervention and breath-coordinated mind-body practice to be used for home practice. Outcome measures: Standard measures of impact were obtained at baseline, 1, 3, 6, and 12 months using the following validated survey instruments: Perceived Stress Scale (PSS), PROMIS Global Health v1.2 (GH), and PROMIS 29 v2.0 survey. Results: From 216 patients presenting for Lyme evaluation, 19 participants enrolled with 84% completing the study (N\u2009=\u200916). Baseline PROMIS GH scores consisting of general Physical Health (GPH) and general Mental Health (GMH) scores were lower in the study population than in the general U.S. population. PROMIS 29 scores were higher for fatigue, anxiety, and pain than those in the general U.S. population. Over 12-month period, improvement in both the GPH and GMH was 6.09 (confidence interval [95% CI]\u2009=\u20092.71-9.46; p\u2009<\u20090.001) and 4.65 (95% CI\u2009=\u20091.50-7.80; p\u2009=\u20090.004), respectively. PROMIS 29 scores showed the greatest improvement in fatigue at -7.91 (95% CI\u2009=\u2009-12.34 to -3.48; p\u2009<\u20090.001), pain interference -5.08 (95% CI\u2009=\u2009-9.20 to -0.96; p\u2009=\u20090.016), and ability to participate in social roles and activities 7.48 (95% CI\u2009=\u20093.21-11.75; p\u2009=\u20090.001) and least with depression -1.82 (95% CI\u2009=\u2009-4.74 to 1.10; p\u2009=\u20090.223). Employment status had significant effects on almost all outcome scores. Postinfectious state was associated with improvement in anxiety and PSS scores. Conclusions: A multimodal Ayurvedic and breath-coordinated mind-body therapeutic intervention is feasible and a potential nonpharmacologic therapeutic option for persons presenting with pain, stress, fatigue, physical dysfunction, and sleep disturbance attributed to a postinfectious syndrome. Further research is needed to determine efficacy in this population and in other groups with similar symptom complexes due to postinfectious syndromes.\n\nID: 37727539\nTitle: Lyme Disease: An Overview.\nAbstract: Lyme disease, a tick-borne multisystem disease, is caused by spirochete Borrelia burgdorferi (sensu lato). It is a common illness in temperate countries, especially the United States, but the incidence is increasing across continents due to increasing reforestation, travel and adventure tourism, increased intrusion in the vector habitat, and changing habitat of the vector. Transmission primarily occurs via bite of an infected tick (Ixodes spp.). The appearance of an erythema migrans rash following a tick bite is diagnostic of early Lyme disease even without laboratory evidence. Borrelia lymphocytoma and acrodermatitis chronica atrophicans along with multisystem involvement occur in late disseminated and chronic stages. A two-step serologic testing protocol using an enzyme-linked immunosorbent assay (ELISA) followed by confirmation of positive and equivocal results by Western immunoblot is recommended for the diagnosis. Transplacental transmission to infant occurs in the first trimester with possible congenital Lyme disease making treatment imperative during antenatal period. The treatment is most effective in the early stages of the disease, whereas rheumatological, neurological, or other late manifestations remain difficult to treat with antibiotics alone. Treatment with oral doxycycline is preferred for its additional activity against other tick-borne illnesses which may occur concurrently in 10%-15% of cases. New-generation cephalosporins and azithromycin are alternative options in patients with doxycycline contraindications. No vaccine is available and one episode of the disease will not confer life-long immunity; thus, preventive measures remain a priority. The concept of post-Lyme disease syndrome versus chronic Lyme disease remains contested for want of robust evidence favoring benefits of prolonged antibiotic therapy.\n\nID: 37101730\nTitle: A Comprehensive Review of Herbal Supplements Used for Persistent Symptoms Attributed to Lyme Disease.\nAbstract: Lyme disease is the most common, tick-borne disease in the USA. While most patients successfully recover with antibiotics, some patients experience persistent symptoms for months to years. Patients who attribute chronic symptoms to Lyme disease commonly use herbal supplements. The complexity, variability in dose and formulation, and lack of data for these herbal compounds make it difficult to assess their efficacy and safety. This review examines the evidence for the antimicrobial activity, safety, and drug-drug interactions of 18 herbal supplements that patients commonly use for treatment of persistent symptoms attributed to Lyme disease. The research team performed a narrative review by searching the PubMed, Embase, Scopus, Natural Medicines databases, and NCCIH website. The search used the keywords for 18 herbal compounds: (1) andrographis (Andrographis paniculate), (2) astragalus (Astragalus propinquus), (3) berberine, (4) cat's claw bark (Uncaria tomentosa), (5) cordyceps (Cordyceps sinensis), (6) cryptolepis (Cryptolepis sanguinolenta), (7) Chinese skullcap (Scutellaria baicalensis), (8) garlic (Allium sativum), (9) Japanese knotwood (Polygonum cuspidatum), (10) reishi mushrooms (Ganoderma lucidum), (11) sarsaparilla (Smilax medica), (12) Siberian ginseng (Eleutherococcus senticosus), (13) sweet wormwood (Artemisia annua), (14) teasle root (Dipsacus fullonum), (15) lemon balm (Melissa officinalis), (16) oil of oregano (Origanum vulgare), (17) peppermint (Mentha x piperita), and (18) thyme (Thymus vulgaris). The team also searched for terms related to protocols, including Dr. Rawls' protocol and the Buhner protocol. University of Maryland Medical Center, Baltimore MD. Seven of the 18 herbs reviewed had evidence for in-vitro activity against B. burgdorferi. These compounds included: (1) cat's claw (2) cryptolepis, (3) Chinese skullcap, (4) Japanese knotweed, (5) sweet wormwood, (6) thyme, and (7) oil of oregano. With the exception of oil of oregano these compounds also have anti-inflammatory activity. In vivo data and clinical trials are lacking. Clinicians should be cautious as many of the identified compounds have drug interactions and additive effects that could lead to increased risks for bleeding, hypotension, and hypoglycemia. Many of the herbs that alternative and integrative practitioners use to treat Lyme disease have anti-inflammatory effects that may contribute to patients' perceptions of symptomatic improvement. Some herbs have limited demonstrated anti-borrelial activity in vitro, but in-vivo data and clinical trial data is lacking. Further research is required to determine the efficacy, safety and appropriate use of these herbs for this patient population.\n\nID: 36380166\nTitle: Assessment of cognitive function, structural brain changes and fatigue 6\u00a0months after treatment of neuroborreliosis.\nAbstract: Complete recovery after adequately treated neuroborreliosis is common, but studies report that some patients experience persistent symptoms like self-reported cognitive problems and fatigue. Persisting symptoms are often termed post-Lyme disease syndrome, of which etiology is not clearly understood. The aim of this study was to investigate cognitive function, possible structural changes in brain regions and level of fatigue. We have not found previous studies on neuroborreliosis that use standardized neuropsychological tests and MRI with advanced image processing to investigate if there are subtle regional changes in cortical thickness and brain volumes after treatment. We examined 68 patients treated for neuroborreliosis 6\u00a0months earlier and 66 healthy controls, with a comprehensive neuropsychological test protocol, quantitative structural MRI analysis of the brain and Fatigue Severity Scale. We found no differences between the groups in either cognitive function, cortical thickness or brain volumes. The patients had higher score on Fatigue Severity Scale 3.8 vs. 2.9 (p\u2009=\u20090.001), and more patients (25.4%) than controls (5%) had severe fatigue (p\u2009=\u20090.002), but neither mean score nor proportion of patients with severe fatigue differed from findings in the general Norwegian population. The prognosis regarding cognitive function, brain MRI findings and fatigue after adequately treated neuroborreliosis is favorable.\n\nID: 35782673\nTitle: Disulfiram: A Repurposed Drug in Preclinical and Clinical Development for the Treatment of Infectious Diseases.\nAbstract: This article reviews preclinical and clinical studies on the repurposed use of disulfiram (Antabuse) as an antimicrobial agent. Preclinical research covered on the alcohol sobriety aid includes uses as an anti-MRSA agent, a carbapenamase inhibitor, antifungal drug for candidiasis, and treatment for parasitic diseases due to protozoa (e.g., giardiasis, leishmaniasis, malaria) and helminthes (e.g., schistosomiasis, trichuriasis). Past, current, and pending clinical studies on disulfiram as a post-Lyme disease syndrome (PTLDS) therapy, an HIV latency reversal agent, and intervention for COVID-19 infections are also reviewed..\n\nID: 31579470\nTitle: A case of Mycobacterium goodii infection related to an indwelling catheter placed for the treatment of chronic symptoms attributed to Lyme disease.\nAbstract: Mycobacterium goodii has only rarely been reported to cause invasive disease in humans. Previously reported cases of M. goodii infection have included prosthetic joint infections, pacemaker pocket infections, and pneumonia. We present a case of M. goodii bacteremia with concomitant pulmonary septic emboli that developed in a 32-year-old woman with an indwelling central venous catheter (CVC). The CVC had been placed one year previously for intermittent treatment with intravenous, broadspectrum antibiotics, administered by an outside physician for the treatment of symptoms attributed to chronic Lyme disease. Despite our recommendations, the patient declined follow-up in our Infectious Diseases clinic, opting to continue care under her chronic Lyme disease physician. This case clearly demonstrates the potential for serious medical complications that can arise from the inappropriate use of longterm intravenous antibiotics using a CVC to treat non-specific symptoms attributed to Lyme disease and patients should be counseled regarding these risks.\n\nID: 31488744\nTitle: The prevalence of Lyme disease and associated co-infections in people with a chronic post-concussive syndrome.\nAbstract: There is increasing awareness that Lyme borreliosis (LB) and traumatic brain injury (TBI) may cause mental health symptoms. TBI and Lyme disease compromise the health and activities of millions of patients per year. The chronic symptoms and disability of TBI and Lyme disease share a similar clinical presentation. We have identified an alarming number of individuals suffering from post-concussion syndrome (PCS) that are refractory to care and that have serologically tested positive for Lyme disease. A single-center retrospective review of patient charts that were symptomatic a minimum of one year after a TBI that were tested for Lyme disease to ascertain if there was a relationship. 217 PCS patient records (93 females with a mean age of 34 years, 120 males with a mean age of 40 years and 4 individuals with unknown gender) were included in the review. 38% had a positive Western Blot Igenex IgM. There was a statistically significant relationship of a positive Western Blot Igenex IGM predicting chronic PCS Pearson \u03c72(1)=6.8866, P=0.009, Fisher's exact score p=0.015 and \u03c6=0.2813 representing a moderate effect size. Long term PCS over one year's duration is associated with undiagnosed Lyme disease. There was statistical and substantive significance between individuals with chronic PCS having a positive Western Blot Igenex IgM. Males were more likely to have a positive Western Blot Igenex IgM than females.\n\nID: 29672671\nTitle: Adverse Events Associated With Antibiotics and Intravenous Therapies for Post-Lyme Disease Syndrome in a Commercially Insured Sample.\nAbstract: Non-guideline-endorsed posttreatment courses of antibiotics for post-Lyme disease syndrome (PLDS) have been linked to adverse patient outcomes, but these findings have yet to be validated in large systematic evaluations. A retrospective cohort analysis of medical and pharmacy claims derived from the Truven Health Market Scan Commercial Claims and Encounters Database assessed 90-day incidence rates of adverse events (AEs) associated with PLDS treatment (PLDS-Tx). Patients were diagnosed with PLDS \u22656 months after initial diagnosis and standard antibiotic treatment for Lyme disease. Comparison cohorts included intravenous (IV) PLDS-Tx with or without oral antibiotics; oral antibiotic-only PLDS-Tx; or neither. Composite AE incidence rates were higher for patients treated with IV or oral PLDS-Tx than for patients not receiving either treatment (18.7%, 16.8%, and 13.4%, respectively; P = .019). Significant between-group differences in AE incidence rates were noted for electrolyte imbalance (4.0%, 1.5%, and 0.7%, respectively; P = .001) and infection (14.0%, 12.7%, and 9.3%; P = .006). Infection prevalence increased by 22.0% in the IV treatment group and 17.7% in the oral group. Incidence rates for all-cause and AE-related hospital stays and emergency department visits were higher for treated than nontreated patients, particularly when treatment was IV (all P < .01). Of IV-treated patients, 7.3% experienced an incident all-cause inpatient stay and 11.3% an incident all-cause emergency department visit, compared with, respectively, 2.2% and 3.4% of those treated with oral antibiotics and 0.9% and 1.9% of nontreated patients. Use of IV therapies or oral antibiotics for PLDS was associated with increased patient morbidity within 90 days.\n\nID: 29157500\nTitle: Unraveling Diagnostic Uncertainty Surrounding Lyme Disease in Children with Neuropsychiatric Illness.\nAbstract: Lyme disease is endemic in parts of the United States, including New England, the Atlantic seaboard, and Great Lakes region. The presentation has various manifestations, many of which can mimic psychiatric diseases in children. Distinguishing manifestations of Lyme disease from those of psychiatric illnesses is complicated by inexact diagnostic tests and misuse of these tests when they are not clinically indicated. This article aims to describe manifestations of Lyme disease in children with an emphasis on Lyme neuroborreliosis. Clinical scenarios will be presented and discussed. Finally, recommendations for clinical psychiatrists who encounter children with possible Lyme disease are presented.\n\nID: 29075628\nTitle: Selective Essential Oils from Spice or Culinary Herbs Have High Activity against Stationary Phase and Biofilm Borrelia burgdorferi.\nAbstract: Although the majority of patients with acute Lyme disease can be cured with the standard 2-4\u2009week antibiotic treatment, about 10-20% of patients continue suffering from chronic symptoms described as posttreatment Lyme disease syndrome. While the cause for this is debated, one possibility is that persister bacteria are not killed by the current Lyme antibiotics and remain active in the system. It has been reported that essential oils have antimicrobial activities and some have been used by patients with persisting Lyme disease symptoms. However, the activity of essential oils against the causative agent Borrelia burgdorferi (B. burgdorferi) has not been well studied. Here, we evaluated the activity of 34 essential oils against B. burgdorferi stationary phase culture as a model for persister bacteria. We found that not all essential oils had activity against the B. burgdorferi stationary phase culture, with top five essential oils (oregano, cinnamon bark, clove bud, citronella, and wintergreen) at a low concentration of 0.25% showing high anti-persister activity that is more active than the known persister drug daptomycin. Interestingly, some highly active essential oils were found to have excellent anti-biofilm ability as shown by their ability to dissolve the aggregated biofilm-like structures. The top three hits, oregano, cinnamon bark, and clove bud completely eradicated all viable cells without any regrowth in subculture in fresh medium, whereas but not citronella and wintergreen did not have this effect. Carvacrol was found to be the most active ingredient of oregano oil showing excellent activity against B. burgdorferi stationary phase cells, while other ingredients of oregano oil p-cymene and \u03b1-terpinene had no apparent activity. Future studies are needed to characterize and optimize the active essential oils in drug combination studies in vitro and in vivo and to address their safety and pharmacokinetic properties before they can be considered as a novel treatment of persistent Lyme disease.\n\nID: 26631681\nTitle: Living in Limbo: Contested Narratives of Patients With Chronic Symptoms Following Lyme Disease.\nAbstract: Persistent, subjective symptoms of unknown etiology following treatment for Lyme disease have been termed post- treatment Lyme disease syndrome or chronic Lyme disease (PTLDS/CLD). The objective of this study was to give primacy to the patient experience of this medically contested condition by eliciting patient illness narratives and identifying emergent issues through semistructured interviews conducted among 29 participants. We used thematic narrative analysis to identify three predominant themes: (a) Physical and social limitations lead to a \"new normal\" characterized by fundamental shifts of ways of being in the world, (b) disease-specific factors contribute to symptom and illness invisibility that affects social support in nuanced ways, and (c) pervasive medical uncertainty regarding PTLDS/CLD promotes an increased sense of personal responsibility for care. Similar to other contested or medically unexplained syndromes, our findings suggest that the social sequelae of PTLDS/CLD can be equally protracted as the physical effects of this illness.\n\nID: 26593256\nTitle: Clinical Manifestations and Treatment of Lyme Disease.\nAbstract: Lyme disease is the most common tick-borne illness in the United States and is also seen in areas of Europe and Asia. The growing deer and Ixodes species tick populations in many areas underscore the importance of clinicians to properly recognize and treat the different stages of Lyme disease. Controversy regarding the cause and management of persistent symptoms following treatment of Lyme disease persists and is highlighted in this review.\n\nID: 27407225\nTitle: Post-Lyme disease syndrome.\nAbstract: About 10% of patients with Lyme disease continue to experience musculoskeletal pain and cognitive dysfunction after recommended antibiotic treatment. This condition is called post-Lyme disease syndrome (PLDS) or post-treatment Lyme disease syndrome. These two terms are used interchangeably. The pathogenesis of PLDS has been controversial. The hypothesis that patients with PLDS may harbor hidden reservoirs of Borrelia burgdorferi after their initial antibiotic treatment is difficult to accept. The prospective, double-blind studies contradict this point of view. Also, recently published research applying xenodiagnosis to PLDS supports the opinion that PLDS most likely has an autoimmune background. Lengthy courses of antibiotics are not justified in patients with PLDS because of the lack of benefit, and they are fraught with hazards. Most patients with PLDS recover from persistent symptoms with time. However, it can take months before they feel completely well.\n\nID: 25490690\nTitle: Update on persistent symptoms associated with Lyme disease.\nAbstract: Lyme disease, caused by Borrelia burgdorferi, is the most common vector-borne illness in the United States. The pathogenesis, ecology, and epidemiology of Lyme disease have been well described, and antimicrobial treatment is very effective. There has been controversy about whether infection can persist and cause chronic symptoms despite treatment with antimicrobials. This review summarizes recent studies that have addressed this issue. The pathogenesis of persistent nonspecific symptoms in patients who were treated for Lyme disease is poorly understood, and the validity of results of attempts to demonstrate persistent infection with B. burgdorferi has not been established. One study attempted to use xenodiagnosis to detect B. burgdorferi in patients who have been treated for Lyme disease. Another study assessed whether repeated episodes of erythema migrans were due to the same or different strains of B. burgdorferi. A possible cause of persistent arthritis in some treated patients is slow clearance of nonviable organisms that may lead to prolonged inflammation. The results of all of these studies continue to provide evidence that viable B. burgdorferi do not persist in patients who receive conventional antimicrobial treatment for Lyme disease. Patients with persistent symptoms possibly associated with Lyme disease often provide a challenge for clinicians. Recent studies have provided additional evidence that viable B. burgdorferi do not persist after conventional treatment with antimicrobials, indicating that ongoing symptoms in patients who received conventional treatment for Lyme disease should not be attributed to persistent active infection.\n\nID: 24830783\nTitle: A tale of two syndromes: Lyme disease preceding postural orthostatic tachycardia syndrome.\nAbstract: The pathogenesis of postural orthostatic tachycardia syndrome (POTS) is poorly understood. However, it has been suggested that altered immune activity or denervation of the autonomic system following illness may be an important trigger. Patients infected with Lyme disease have a small incidence of post-Lyme disease syndrome that share similar characteristics to POTS. We report a short series of two women who present with persistent symptoms of orthostatic intolerance consistent with POTS after treated Lyme disease.\n\nID: 24198341\nTitle: Lyme disease in the United Kingdom.\nAbstract: Lyme disease, while still an uncommon disease in the UK, is on the increase. Case numbers have increased by 3.6-fold since 2001, with over 950 cases reported by the Health Protection Agency (HPA) in 2011, compared with less than 500 cases annually pre-2004. HPA indications of the true incidence are suggested to be closer to 3000 cases/year, of which around 82% of cases are indigenously acquired. Three genospecies, Borrelia burgdorferi sensu stricto, Borrelia afzelli and Borrelia garinii, represent the predominant pathogenic variants in the UK. Erythema migrans is the commonest manifestation, occurring in 60%-91% of cases. In the UK, neuroborelliosis is the most common complication, while myocarditis is unusual, and death from either conduction disease or carditis is extremely rare. The role of Borrelia infection in chronic dilated cardiomyopathy in the UK remains unproven. Controversy over the existence of either 'chronic Lyme disease' and/or 'post-Lyme disease syndrome' continues unabated. National medical societies, patient advocacy groups, insurance companies, lawyers, doctors, the private health medical sector and scientific journals have all become embroiled in this bitter controversy. New developments include diagnostic tests able to detect Lyme disease at an earlier stage, shorter durations of antibiotic therapy and potential advances in vaccines against Borrelia.\n\nID: 23190290\nTitle: Chronic Lyme; diagnostic and therapeutic challenges.\nAbstract: In this review, we aim to discuss the definition, clinical and laboratory features, diagnostics, and management of chronic Lyme. Chronic Lyme is a rare condition caused by long-lasting and ongoing infection with the spirochete Borrelia burgdorferi (Bb). The most common manifestations are progressive encephalitis, myelitis, acrodermatitis chronica atrophicans with or without neuropathy, and arthritis. Chronic Lyme is not considered to present with isolated subjective symptoms. Direct detection of Bb has low yield in most manifestations of chronic Lyme, while almost 100% of the cases are seropositive, that is, have detectable Bb IgG antibodies in serum. Detection of Bb antibodies only with Western blot technique and not with ELISA and detection of Bb IgM antibodies without simultaneous detection of Bb IgG antibodies should be considered as seronegativity in patients with long-lasting symptoms. Patients with chronic Lyme in the nervous system (neuroborreliosis) have, with few exceptions, pleocytosis and production of Bb antibodies in their cerebrospinal fluid. Strict guidelines should be applied in diagnostics of chronic Lyme, and several differential diagnoses, including neurological disease, rheumatologic disease, post-Lyme disease syndrome, chronic fatigue syndrome, and psychiatric disease, should be considered in the diagnostic workup. Antibiotic treatment with administration route and dosages according to current guidelines are recommended. Combination antimicrobial therapy or antibiotic courses longer than 4 weeks are not recommended. Patients who attribute their symptoms to chronic Lyme on doubtful basis should be offered a thorough and systematic diagnostic approach, and an open and respectful dialogue.\n\nID: 21778118\nTitle: Epitope mapping of antibodies to VlsE protein of Borrelia burgdorferi in post-Lyme disease syndrome.\nAbstract: The VlsE lipoprotein of Borrelia burgdorferi elicits a strong immune response during the course of Lyme disease. The present study was aimed at characterization of the epitopes of VlsE targeted by the antibody response in patients with post-Lyme disease syndrome, a condition characterized by persisting symptoms of pain, fatigue, and/or neurocognitive impairment despite antibiotic treatment of B. burgdorferi infection. Epitope mapping was carried out using microarrays that contained synthesized overlapping peptides covering the full sequence of VlsE from B. burgdorferi B31. In addition to the previously characterized IR6 region in the variable domain, specific sequences in the N- and C-terminal invariable domains of VlsE were found to be major B cell epitopes in affected patients. The crystal structure of VlsE indicated that the newly described epitopes form a contiguous region in the surface-exposed membrane-proximal part of the monomeric form of the protein.\n\nID: 21411605\nTitle: Anti-Borrelia burgdorferi antibody profile in post-Lyme disease syndrome.\nAbstract: Patients with post-Lyme disease syndrome (PLDS) report persistent symptoms of pain, fatigue, and/or concentration and memory disturbances despite antibiotic treatment for Lyme borreliosis. The etiopathogenesis of these symptoms remains unknown and no effective therapies have been identified. We sought to examine the antiborrelia antibody profile in affected patients with the aim of finding clues to the mechanism of the syndrome and its relationship to the original spirochetal infection. Serum specimens from 54 borrelia-seropositive PLDS patients were examined for antibodies to Borrelia burgdorferi proteins p18, p25, p28, p30, p31, p34, p39, p41, p45, p58, p66, p93, and VlsE by automated immunoblotting and software-assisted band analysis. The presence of serum antibodies to the 31-kDa band was further investigated by examination of reactivity against purified recombinant OspA protein. Control specimens included sera from 14 borrelia-seropositive individuals with a history of early localized or disseminated Lyme disease who were symptom free (post-Lyme healthy group), as well as 20 healthy individuals without serologic evidence or history of Lyme disease. In comparison to the post-Lyme healthy group, higher frequencies of antibodies to p28 (P < 0.05), p30 (P < 0.05), p31 (P < 0.0001), and p34 (P < 0.05) proteins were found in the PLDS group. Assessment of antibody reactivity to recombinant OspA confirmed the presence of elevated levels in PLDS patients (P < 0.005). The described antiborrelia antibody profile in PLDS offers clues about the course of the antecedent infection in affected patients, which may be useful for understanding the pathogenic mechanism of the disease.\n\nID: 20227484\nTitle: Anti-neural antibody reactivity in patients with a history of Lyme borreliosis and persistent symptoms.\nAbstract: Some Lyme disease patients report debilitating chronic symptoms of pain, fatigue, and cognitive deficits despite recommended courses of antibiotic treatment. The mechanisms responsible for these symptoms, collectively referred to as post-Lyme disease syndrome (PLS) or chronic Lyme disease, remain unclear. We investigated the presence of immune system abnormalities in PLS by assessing the levels of antibodies to neural proteins in patients and controls. Serum samples from PLS patients, post-Lyme disease healthy individuals, patients with systemic lupus erythematosus, and normal healthy individuals were analyzed for anti-neural antibodies by immunoblotting and immunohistochemistry. Anti-neural antibody reactivity was found to be significantly higher in the PLS group than in the post-Lyme healthy (p<0.01) and normal healthy (p<0.01) groups. The observed heightened antibody reactivity in PLS patients could not be attributed solely to the presence of cross-reactive anti-borrelia antibodies, as the borrelial seronegative patients also exhibited elevated anti-neural antibody levels. Immunohistochemical analysis of PLS serum antibody activity demonstrated binding to cells in the central and peripheral nervous systems. The results provide evidence for the existence of a differential immune system response in PLS, offering new clues about the etiopathogenesis of the disease that may prove useful in devising more effective treatment strategies.\n\nID: 19930447\nTitle: EFNS guidelines on the diagnosis and management of European Lyme neuroborreliosis.\nAbstract: Lyme neuroborreliosis (LNB) is a nervous system infection caused by Borrelia burgdorferi sensu lato (Bb). To present evidence-based recommendations for diagnosis and treatment. Data were analysed according to levels of evidence as suggested by EFNS. The following three criteria should be fulfilled for definite LNB, and two of them for possible LNB: (i) neurological symptoms; (ii) cerebrospinal fluid (CSF) pleocytosis; (iii) Bb-specific antibodies produced intrathecally. PCR and CSF culture may be corroborative if symptom duration is <6 weeks, when Bb antibodies may be absent. PCR is otherwise not recommended. There is also not enough evidence to recommend the following tests for diagnostic purposes: microscope-based assays, chemokine CXCL13, antigen detection, immune complexes, lymphocyte transformation test, cyst formation, lymphocyte markers. Adult patients with definite or possible acute LNB (symptom duration <6 months) should be offered a single 14-day course of antibiotic treatment. Oral doxycycline (200 mg daily) and intravenous (IV) ceftriaxone (2 g daily) are equally effective in patients with symptoms confined to the peripheral nervous system, including meningitis (level A). Patients with CNS manifestations should be treated with IV ceftriaxone (2 g daily) for 14 days and late LNB (symptom duration >6 months) for 3 weeks (good practice points). Children should be treated as adults, except that doxycycline is contraindicated under 8 years of age (nine in some countries). If symptoms persist for more than 6 months after standard treatment, the condition is often termed post-Lyme disease syndrome (PLDS). Antibiotic therapy has no impact on PLDS (level A).\n\nID: 32546581\nTitle: Supporting patients with long-term problems after Lyme disease.\nAbstract: \n\nID: 19108522\nTitle: [Failures of antibiotic treatment in Lyme arthritis].\nAbstract: Antibiotic treatment has been proven to be effective in about 90% of patients with Lyme arthritis in controlled studies. Overt arthritis persisting in spite of antibiotic therapy is rare and most likely has an autoimmune background. More frequently, patients with history of Lyme borreliosis present with non-specific articular and musculosceletal symptoms, which seem to be permanent sequelae of arthritis or constitute part of so called post-Lyme disease syndrome, of unclear pathogenesis. As persistence of active infection after proper antibiotic therapy is unlikely, repeated treatment seems of no benefit in most of the patients. No more than 2-3 attempts of antibiotic therapy should be undertaken; if symptoms persist, symptomatic and anti-inflammatory treatment should be introduced. Lack of response to antibiotics should also point to co-existing musculoskeletal morbidity or to improper diagnosis of Lyme borreliosis, which is frequent due to common occurrence of false-positive serologic tests results.\n\nID: 18452802\nTitle: Lyme arthritis: pathogenesis, clinical presentation, and management.\nAbstract: Arthritis is one of the most prominent features of Lyme disease, the tick-borne illness caused by Borrelia burgdorferi. Although the pathogenesis of Lyme arthritis is complex and still under study, the clinical presentation and natural history have been established by long-term observation of untreated and treated patients. This review addresses the clinical presentation of Lyme arthritis as a mono- or oligoarticular relapsing/remitting arthritis primarily affecting the large joints and describes presentations in which arthralgias rather than arthritis are seen. Strategies for diagnosis and treatment are discussed, and methods are reviewed for addressing treatment-refractory Lyme arthritis and arthralgias that may occur after treatment of Lyme disease (sometimes as a component of what is known as the post-Lyme disease syndrome).\n\nID: 17605053\nTitle: Differential diagnoses of suspected Lyme borreliosis or post-Lyme-disease syndrome.\nAbstract: The symptoms of Lyme borreliosis are similar to those of a variety of autoimmune musculoskeletal diseases. Persistence of complaints is frequently interpreted as unsuccessful antibiotic treatment of Borrelia-associated infections. However, such refractory cases are rare, and re-evaluation of differential diagnoses helps to avoid the substantial risk of long-term antibiotic therapy. In this study, we analyzed patients who presented to our rheumatology unit with previous suspected or diagnosed Lyme borreliosis. Eighty-six patients from a 3.5-year period were evaluated. The mean age of patients was 49.2 +/- 17.2 years; 60% (n = 52) reported a tick bite and 33% (n = 28) an erythema. Forty-seven percent (n = 39) had positive enzyme-linked immunoassay results and Western blots (Mikrogen, Martinsried, Germany). All but 12 patients had already received antibiotic treatment previously. Nine percent (n = 8) had ongoing or recent Lyme borreliosis. Twenty-nine percent (n = 25) showed clinical symptoms and radiographic changes compatible with degenerative disorders of the cervical and/or lumbar spine. These patients were significantly older when compared to the other patients (59.3 +/- 13.7 years vs 46.1 +/- 17.2 years, p = 0.001). Seventeen percent (n = 16) had arthropathies related to psoriasis or rheumatoid arthritis. Twelve percent (n = 10) were positive for the HLA B27 antigen. Other diseases were less frequent. Six patients (7%) could not be diagnosed conclusively, and four of these patients had negative Borrelia immunoassay results. In conclusion, Borrelia-associated diseases were rare in this study. Differential diagnoses helped to initiate a successful disease-specific therapeutic strategy.\n\nID: 17578771\nTitle: Point: antibiotic therapy is not the answer for patients with persisting symptoms attributable to lyme disease.\nAbstract: It is not well understood why some patients develop a subjective syndrome that includes considerable fatigue, musculoskeletal aches, and neurocognitive dysfunction after receiving standard antibiotic courses for the treatment of Lyme disease. Some practitioners use the term \"chronic Lyme disease\" and order prolonged courses of oral and parenteral antibiotics, believing that persistent infection with Borrelia burgdorferi is responsible. However, well-performed prospective studies have found neither evidence of chronic infection nor a benefit worthy of long-term antibiotic therapy for these patients. Such extended antibiotic therapy poses hazards and cannot be viewed as acceptable. The term \"chronic Lyme disease\" should be discarded as misleading; rather, the term \"post-Lyme disease syndrome\" better reflects the postinfectious nature of this condition. Further research is necessary to understand possible mechanisms of these chronic symptoms following Lyme disease as well as to find effective therapies.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes. KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions. However, larger, standardized RCTs with active comparators, biomarkers, and longer follow-up are needed.

Based on the provided literature, there is no clinical evidence to support the existence of a \"cure\" for this syndrome. Controlled trials consistently indicate that prolonged antibiotic therapy provides no sustained benefit and carries significant risks of adverse events. Current management strategies emphasize symptom relief and multidisciplinary, non-pharmacological support.\n\n### [INTRODUCTION & JUSTIFICATION]\nPTLDS remains a medically contested entity due to the absence of well-defined diagnostic biomarkers and the lack of evidence for persistent active infection. Multiple systematic reviews and randomized controlled trials (RCTs) have demonstrated that prolonged courses of antibiotics, often used for \"chronic Lyme disease,\" are ineffective for PTLDS and frequently result in serious adverse outcomes, such as infections and hospitalizations. \n\nThe literature underscores that the pathophysiology of PTLDS is poorly understood, with hypotheses ranging from autoimmune responses, permanent tissue damage, or allostatic load to the existence of nonviable antigenic debris. Given the lack of a causative agent or a consistent pathomechanism, no definitive \"cure\" exists in current clinical practice. Instead, research has shifted toward feasibility studies for non-pharmacological interventions, such as online yoga and Ayurveda-based mind-body practices, which may assist in managing symptom burden and improving quality of life, rather than eliminating the syndrome itself.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Evidence suggests that prolonged antibiotic therapy does not address the core symptoms of PTLDS and can introduce significant morbidity.\n*   Diagnosis of PTLDS is purely clinical, as no quantifiable laboratory methods exist to verify the syndrome's presence or resolution.\n*   Some patients diagnosed with \"chronic Lyme disease\" may actually be suffering from other, distinct conditions such as fibromyalgia, chronic fatigue syndrome, or depression.\n*   The prevalence of PTLDS is estimated to occur in approximately 10\u201320% of adequately treated Lyme patients.\n*   Emerging research into MSA/MAA autoantibodies in PTLDS patients points toward potential immune dysregulation as a pathogenetic factor rather than persistent infection.\n*   Yoga and mind-body interventions have demonstrated feasibility and potential in reducing pain and cognitive impairment in PTLDS cohorts.\n*   Misattribution of focal infections (like tonsillitis) as \"chronic Lyme disease\" is a documented source of diagnostic error.\n*   The medical literature explicitly cautions against the use of central venous catheters for long-term antibiotic administration due to risks of serious infections, such as *Mycobacterium goodii*.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The disease is multisystemic, and chronic disease, in particular, may be associated with neuropsychological deficits. However, to date, only a few empirical studies exist, which examine the neuropsychological sequelae associated with chronic Lyme disease. A review of the literature shows that the deficits observed in adults with chronic Lyme disease are generally consistent with the deficits that can be seen in processes with primarily frontal systems involvement. These observations are generally consistent with neuroradiologic findings. The clinical presentation in chronic Lyme disease and the nature of the neuropsychological deficits are discussed, as are several central issues in understanding neuropsychological functioning in chronic Lyme disease, such as the impact of chronic illness, response to treatment, and the relationship between neuropsychological performance and depression, fatigue, and neurological indicators of disease.",

This constellation of symptoms has been variously referred to as \"chronic Lyme disease,\" \"post-Lyme disease syndrome,\" and \"post-treatment chronic Lyme disease.\" Persistent symptoms have been reported in patients who are seropositive for IgG antibodies against Borrelia burgdorferi as well as in patients who are seronegative. The cause or causes of persistent symptoms in these patients have not been clearly defined and are controversial. Because of the temporal association of these symptoms with infection with B. burgdorferi, some patients have been treated with prolonged courses of antibiotics. Case reports and uncontrolled trials have reported the efficacy of prolonged antibiotic therapy, often with relapse of the symptoms after discontinuation of therapy. To date, only one randomized, placebo-controlled, double-blind trial of antibiotic therapy for these patients has been published. An abstract of a second placebo-controlled trial of antibiotic therapy in a smaller cohort has also been presented. This paper will describe this patient population in detail and will review the clinical, microbiological, and selected biochemical and immunologic parameters and their responses to antibiotic treatment in the setting of a controlled trial.",

To determine whether antibiotic therapy improves cognitive function in two randomized double-blind placebo-controlled studies of patients with PTCLD. A total of 129 patients with a physician-documented history of Lyme disease from three study sites in the northeast United States were studied. Seventy-eight were seropositive for IgG antibodies against Borrelia burgdorferi, and 51 were seronegative. Patients in each group were randomly assigned to receive IV ceftriaxone 2 g daily for 30 days followed by oral doxycycline 200 mg daily for 60 days or matching IV and oral placebos. Assessments were made at 90 and 180 days after treatment. Symptom severity was measured from the cognitive functioning, pain, and role functioning scales of the Medical Outcomes Study (MOS). Memory, attention, and executive functioning were assessed using objective tests. Mood was assessed using the Beck Depression Inventory and Minnesota Multiphasic Personality Inventory. There were no significant baseline differences between seropositive and seronegative groups. Both groups reported a high frequency of MOS symptoms, depression, and somatic complaints but had normal baseline neuropsychological test scores. The combined groups showed significant decreases in MOS symptoms, higher objective test scores, and improved mood between baseline and 90 days. However, there were no significant differences between those receiving antibiotics and placebo. Patients with post-treatment chronic Lyme disease who have symptoms but show no evidence of persisting Borrelia infection do not show objective evidence of cognitive impairment. Additional antibiotic therapy was not more beneficial than administering placebo.",
        "17578771": "ID: 17578771\nTitle: Point: antibiotic therapy is not the answer for patients with persisting symptoms attributable to lyme disease.\nAbstract: It is not well understood why some patients develop a subjective syndrome that includes considerable fatigue, musculoskeletal aches, and neurocognitive dysfunction after receiving standard antibiotic courses for the treatment of Lyme disease. Some practitioners use the term \"chronic Lyme disease\" and order prolonged courses of oral and parenteral antibiotics, believing that persistent infection with Borrelia burgdorferi is responsible. However, well-performed prospective studies have found neither evidence of chronic infection nor a benefit worthy of long-term antibiotic therapy for these patients. Such extended antibiotic therapy poses hazards and cannot be viewed as acceptable. The term \"chronic Lyme disease\" should be discarded as misleading; rather, the term \"post-Lyme disease syndrome\" better reflects the postinfectious nature of this condition. Further research is necessary to understand possible mechanisms of these chronic symptoms following Lyme disease as well as to find effective therapies.",
        "17605053": "ID: 17605053\nTitle: Differential diagnoses of suspected Lyme borreliosis or post-Lyme-disease syndrome.\nAbstract: The symptoms of Lyme borreliosis are similar to those of a variety of autoimmune musculoskeletal diseases. Persistence of complaints is frequently interpreted as unsuccessful antibiotic treatment of Borrelia-associated infections. However, such refractory cases are rare, and re-evaluation of differential diagnoses helps to avoid the substantial risk of long-term antibiotic therapy. In this study, we analyzed patients who presented to our rheumatology unit with previous suspected or diagnosed Lyme borreliosis. Eighty-six patients from a 3.5-year period were evaluated. The mean age of patients was 49.2 +/- 17.2 years; 60% (n = 52) reported a tick bite and 33% (n = 28) an erythema. Forty-seven percent (n = 39) had positive enzyme-linked immunoassay results and Western blots (Mikrogen, Martinsried, Germany). All but 12 patients had already received antibiotic treatment previously. Nine percent (n = 8) had ongoing or recent Lyme borreliosis. Twenty-nine percent (n = 25) showed clinical symptoms and radiographic changes compatible with degenerative disorders of the cervical and/or lumbar spine. These patients were significantly older when compared to the other patients (59.3 +/- 13.7 years vs 46.1 +/- 17.2 years, p = 0.001). Seventeen percent (n = 16) had arthropathies related to psoriasis or rheumatoid arthritis. Twelve percent (n = 10) were positive for the HLA B27 antigen. Other diseases were less frequent. Six patients (7%) could not be diagnosed conclusively, and four of these patients had negative Borrelia immunoassay results. In conclusion, Borrelia-associated diseases were rare in this study. Differential diagnoses helped to initiate a successful disease-specific therapeutic strategy.",

Although the pathogenesis of Lyme arthritis is complex and still under study, the clinical presentation and natural history have been established by long-term observation of untreated and treated patients. This review addresses the clinical presentation of Lyme arthritis as a mono- or oligoarticular relapsing/remitting arthritis primarily affecting the large joints and describes presentations in which arthralgias rather than arthritis are seen. Strategies for diagnosis and treatment are discussed, and methods are reviewed for addressing treatment-refractory Lyme arthritis and arthralgias that may occur after treatment of Lyme disease (sometimes as a component of what is known as the post-Lyme disease syndrome).",
        "18452806": "ID: 18452806\nTitle: Chronic Lyme disease: a review.\nAbstract: Studies have shown that most patients diagnosed with chronic Lyme disease either have no objective evidence of previous or current infection with Borrelia burgdorferi or are patients who should be classified as having post-Lyme disease syndrome, which is defined as continuing or relapsing nonspecific symptoms (such as fatigue, musculoskeletal pain, and cognitive complaints) in a patient previously treated for Lyme disease. Despite extensive study, there is currently no clear evidence that post-Lyme disease syndrome is caused by persistent infection with B burgdorferi. Four randomized placebo-controlled studies have shown that antibiotic therapy offers no sustained benefit to patients who have post-Lyme disease syndrome. These studies also showed a substantial placebo effect and a significant risk of treatment-related adverse events. Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed.",

The purpose of this brief report is to review what is known from clinical research about these conditions to assist both practicing physicians and lawmakers in making sound and safe decisions with respect to treatment.",
        "19108522": "ID: 19108522\nTitle: [Failures of antibiotic treatment in Lyme arthritis].\nAbstract: Antibiotic treatment has been proven to be effective in about 90% of patients with Lyme arthritis in controlled studies. Overt arthritis persisting in spite of antibiotic therapy is rare and most likely has an autoimmune background. More frequently, patients with history of Lyme borreliosis present with non-specific articular and musculosceletal symptoms, which seem to be permanent sequelae of arthritis or constitute part of so called post-Lyme disease syndrome, of unclear pathogenesis. As persistence of active infection after proper antibiotic therapy is unlikely, repeated treatment seems of no benefit in most of the patients. No more than 2-3 attempts of antibiotic therapy should be undertaken; if symptoms persist, symptomatic and anti-inflammatory treatment should be introduced. Lack of response to antibiotics should also point to co-existing musculoskeletal morbidity or to improper diagnosis of Lyme borreliosis, which is frequent due to common occurrence of false-positive serologic tests results.",
        "19268485": "ID: 19268485\nTitle: Insufficient evidence to deny antibiotic treatment to chronic Lyme disease patients.\nAbstract: The severity, length of illness, and cost of chronic Lyme disease (CLD) have been well described. A number of oral, intravenous, and intramuscular antibiotics have been prescribed for CLD. Surprisingly few antibiotic schedules prescribed for the treatment of CLD have been evaluated in randomized double-blind placebo-controlled clinical trials (RCTs). Physicians have increasingly turned to clinical treatment guideline (CPG) panels to judge the mixed results of the evidence. Two CPG panels have looked at the evidence only to reach opposite conclusions: (1) antibiotic therapy for CLD is not effective and (2) antibiotic therapy for CLD is effective. Physicians have been advised by guideline developers to use clinical discretion in diagnosing and treating CLD. Nevertheless, many health insurers - relying exclusively upon only one CPG - have a policy of automatically denying antibiotics to CLD patients regardless of the specifics of each case or the recommendations of the patient's physician. This paper examined the eight limitations of the evidence used to conclude that antibiotics therapy for CLD is not effective in forming the following hypothesis: insufficient evidence to deny antibiotic treatment to CLD patients. There are eight limitations that support the hypothesis: (1) the power of the evidence is inadequate to draw definite conclusions, (2) the evidence is too heterogeneous to make strong recommendations, (3) the risk to an individual of facing a long-term debilitating illness has not been considered, (4) the risk to society of a growing chronically ill population has not been considered, (5) treatment delay has not been considered as a confounder, (6) co-infections have not been considered as a confounder, (7) the design of RCTs did not address the range of treatment options in an actual practice, and (8) the findings cannot be generalized to actual practice. This hypothesis suggests that physicians should consider the limitations of the evidence before denying antibiotic treatment for CLD. Physicians who deny antibiotic treatment to CLD patients might inform their patients that there are some clinicians who disagree with that position, and then offer to refer them for a second opinion to a doctor who could potentially present a different point of view. The hypothesis also suggests that health care insurers should consider the limitations of the evidence before adopting policies that routinely deny antibiotic treatment for CLD patients and should expand coverage of CLD to include clinical discretion for specific clinical situations.",

To determine if the population of patients with chronic Lyme disease differs from the populations of patients with either Lyme disease or post-Lyme disease syndrome by examining the gender of patients with these diagnoses. Data on gender were compiled in this cross-sectional study based on a systematic review of published studies of antibiotic treatment in United States patients with post-Lyme disease syndrome (n = 184) or chronic Lyme disease (n = 490), and on cases of adults with Lyme disease reported to the Centers for Disease Control and Prevention from 2003 to 2005 (n = 43,282). Patients with chronic Lyme disease were significantly more likely to be female than were patients diagnosed with either Lyme disease (odds ratio [OR] 2.42, 95% confidence interval [CI] 1.98-2.94, p < 0.0001) or with post-Lyme disease syndrome (OR 2.32, 95% CI 1.62-3.34, p < 0.0001). Patients with chronic Lyme disease differ with regard to gender from those with either B. burgdorferi infection or post-Lyme disease syndrome. This finding suggests that illnesses with a female preponderance, such as fibromyalgia, chronic fatigue syndrome, or depression, may be misdiagnosed as chronic Lyme disease.",

In mice that were treated with antibiotic therapy, residual spirochetes could be taken up by ticks during a blood meal and could be transmitted to SCID mice. These spirochetes are attenuated; their presence is not associated with either inflammation or disease. In this review the methodology and findings of these studies are critically analyzed, and the significance of the results with regard to human Lyme disease is evaluated, with special emphasis on whether these studies provide useful insights into post-Lyme disease syndrome. A serious methodological concern is the failure to consider the pharmacokinetic-pharmacodynamic properties of the antibiotic in choosing the dosage regimen used. We conclude that there is no scientific evidence to support the hypothesis that such spirochetes, should they exist in humans, are the cause of post-Lyme disease syndrome.",

To present evidence-based recommendations for diagnosis and treatment. Data were analysed according to levels of evidence as suggested by EFNS. The following three criteria should be fulfilled for definite LNB, and two of them for possible LNB: (i) neurological symptoms; (ii) cerebrospinal fluid (CSF) pleocytosis; (iii) Bb-specific antibodies produced intrathecally. PCR and CSF culture may be corroborative if symptom duration is <6 weeks, when Bb antibodies may be absent. PCR is otherwise not recommended. There is also not enough evidence to recommend the following tests for diagnostic purposes: microscope-based assays, chemokine CXCL13, antigen detection, immune complexes, lymphocyte transformation test, cyst formation, lymphocyte markers. Adult patients with definite or possible acute LNB (symptom duration <6 months) should be offered a single 14-day course of antibiotic treatment. Oral doxycycline (200 mg daily) and intravenous (IV) ceftriaxone (2 g daily) are equally effective in patients with symptoms confined to the peripheral nervous system, including meningitis (level A). Patients with CNS manifestations should be treated with IV ceftriaxone (2 g daily) for 14 days and late LNB (symptom duration >6 months) for 3 weeks (good practice points). Children should be treated as adults, except that doxycycline is contraindicated under 8 years of age (nine in some countries). If symptoms persist for more than 6 months after standard treatment, the condition is often termed post-Lyme disease syndrome (PLDS). Antibiotic therapy has no impact on PLDS (level A).",

The mechanisms responsible for these symptoms, collectively referred to as post-Lyme disease syndrome (PLS) or chronic Lyme disease, remain unclear. We investigated the presence of immune system abnormalities in PLS by assessing the levels of antibodies to neural proteins in patients and controls. Serum samples from PLS patients, post-Lyme disease healthy individuals, patients with systemic lupus erythematosus, and normal healthy individuals were analyzed for anti-neural antibodies by immunoblotting and immunohistochemistry. Anti-neural antibody reactivity was found to be significantly higher in the PLS group than in the post-Lyme healthy (p<0.01) and normal healthy (p<0.01) groups. The observed heightened antibody reactivity in PLS patients could not be attributed solely to the presence of cross-reactive anti-borrelia antibodies, as the borrelial seronegative patients also exhibited elevated anti-neural antibody levels. Immunohistochemical analysis of PLS serum antibody activity demonstrated binding to cells in the central and peripheral nervous systems. The results provide evidence for the existence of a differential immune system response in PLS, offering new clues about the etiopathogenesis of the disease that may prove useful in devising more effective treatment strategies.",

The etiopathogenesis of these symptoms remains unknown and no effective therapies have been identified. We sought to examine the antiborrelia antibody profile in affected patients with the aim of finding clues to the mechanism of the syndrome and its relationship to the original spirochetal infection. Serum specimens from 54 borrelia-seropositive PLDS patients were examined for antibodies to Borrelia burgdorferi proteins p18, p25, p28, p30, p31, p34, p39, p41, p45, p58, p66, p93, and VlsE by automated immunoblotting and software-assisted band analysis. The presence of serum antibodies to the 31-kDa band was further investigated by examination of reactivity against purified recombinant OspA protein. Control specimens included sera from 14 borrelia-seropositive individuals with a history of early localized or disseminated Lyme disease who were symptom free (post-Lyme healthy group), as well as 20 healthy individuals without serologic evidence or history of Lyme disease. In comparison to the post-Lyme healthy group, higher frequencies of antibodies to p28 (P < 0.05), p30 (P < 0.05), p31 (P < 0.0001), and p34 (P < 0.05) proteins were found in the PLDS group. Assessment of antibody reactivity to recombinant OspA confirmed the presence of elevated levels in PLDS patients (P < 0.005). The described antiborrelia antibody profile in PLDS offers clues about the course of the antecedent infection in affected patients, which may be useful for understanding the pathogenic mechanism of the disease.",

This is exacerbated by the lack of a clinical or microbiologic definition, and the commonality of chronic symptoms in the general population. An accumulating body of evidence suggests that Lyme disease is the appropriate diagnosis for only a minority of patients in whom it is suspected. In prospective studies of Lyme disease, very few patients go on to have a chronic syndrome dominated by subjective complaints. There is no systematic evidence that Borrelia burgdorferi, the etiology of Lyme disease, can be identified in patients with chronic symptoms following treated Lyme disease. Multiple prospective trials have revealed that prolonged courses of antibiotics neither prevent nor alleviate such post-Lyme syndromes.

Transmission occurs primarily through the bite of an infected deer tick (Ixodes scapularis). Identification of an erythema migrans rash following a tick bite is the only clinical manifestation sufficient to make the diagnosis of Lyme disease in the absence of laboratory confirmation. The Centers for Disease Control and Prevention recommends a two-tier serologic testing protocol using an enzyme-linked immunosorbent assay initially, followed by the more specific Western blot to confirm the diagnosis when the assay samples are positive or equivocal. The treatment of Lyme disease is determined mainly by the clinical manifestations of the disease. Doxycycline is often the preferred agent for oral treatment because of its activity against other tick-borne illnesses. Preventive measures include avoiding areas with high tick burdens, wearing protective clothing, using tick repellants (e.g., diethyltoluamide [DEET]), performing frequent body checks and bathing following outdoor activities, and instituting environmental landscape modifications (e.g., grass mowing, deer exclusion fencing) to reduce the tick burden.

Chronic Lyme is a rare condition caused by long-lasting and ongoing infection with the spirochete Borrelia burgdorferi (Bb). The most common manifestations are progressive encephalitis, myelitis, acrodermatitis chronica atrophicans with or without neuropathy, and arthritis. Chronic Lyme is not considered to present with isolated subjective symptoms. Direct detection of Bb has low yield in most manifestations of chronic Lyme, while almost 100% of the cases are seropositive, that is, have detectable Bb IgG antibodies in serum. Detection of Bb antibodies only with Western blot technique and not with ELISA and detection of Bb IgM antibodies without simultaneous detection of Bb IgG antibodies should be considered as seronegativity in patients with long-lasting symptoms. Patients with chronic Lyme in the nervous system (neuroborreliosis) have, with few exceptions, pleocytosis and production of Bb antibodies in their cerebrospinal fluid. Strict guidelines should be applied in diagnostics of chronic Lyme, and several differential diagnoses, including neurological disease, rheumatologic disease, post-Lyme disease syndrome, chronic fatigue syndrome, and psychiatric disease, should be considered in the diagnostic workup. Antibiotic treatment with administration route and dosages according to current guidelines are recommended. Combination antimicrobial therapy or antibiotic courses longer than 4 weeks are not recommended. Patients who attribute their symptoms to chronic Lyme on doubtful basis should be offered a thorough and systematic diagnostic approach, and an open and respectful dialogue.",

The incidence has been increasing, as has the number of patients with persistent symptoms attributed to Borrelia. These symptoms, also referred to as post-Lyme disease syndrome, may follow an erythema migrans or other Lyme manifestations, and include pain, fatigue, and cognitive disturbances.

The PLEASE study is a double-blind, randomized, placebo-controlled trial. Based on power analysis and compensating for possible loss to follow-up, a minimum of 255 patients with borreliosis-attributed persistent symptoms are included. These symptoms are either (a) temporally related to an erythema migrans or otherwise proven symptomatic borreliosis, or (b) accompanied by a positive B. burgdorferi IgG or IgM immunoblot. All patients receive open-label ceftriaxone for two weeks. Patients are then randomized (ratio 1:1:1) to blinded oral follow-up treatment for 12 weeks with (I) doxycycline, (II) clarithromycin combined with hydroxychloroquine, or (III) placebo.

The pathogenesis, ecology, and epidemiology of Lyme disease have been well described, and antimicrobial treatment is very effective. There has been controversy about whether infection can persist and cause chronic symptoms despite treatment with antimicrobials. This review summarizes recent studies that have addressed this issue. The pathogenesis of persistent nonspecific symptoms in patients who were treated for Lyme disease is poorly understood, and the validity of results of attempts to demonstrate persistent infection with B. burgdorferi has not been established. One study attempted to use xenodiagnosis to detect B. burgdorferi in patients who have been treated for Lyme disease. Another study assessed whether repeated episodes of erythema migrans were due to the same or different strains of B. burgdorferi. A possible cause of persistent arthritis in some treated patients is slow clearance of nonviable organisms that may lead to prolonged inflammation. The results of all of these studies continue to provide evidence that viable B. burgdorferi do not persist in patients who receive conventional antimicrobial treatment for Lyme disease. Patients with persistent symptoms possibly associated with Lyme disease often provide a challenge for clinicians. Recent studies have provided additional evidence that viable B. burgdorferi do not persist after conventional treatment with antimicrobials, indicating that ongoing symptoms in patients who received conventional treatment for Lyme disease should not be attributed to persistent active infection.",

Why these phenomena occur is unclear, but possibilities include host responses, antigenic debris, or B. burgdorferi organisms remaining despite antibiotic therapy. In vitro, B. burgdorferi developed increasing antibiotic tolerance as morphology changed from typical spirochetal form in log phase growth to variant round body and microcolony forms in stationary phase. B. burgdorferi appeared to have higher persister frequencies than E. coli as a control as measured by SYBR Green I/propidium iodide (PI) viability stain and microscope counting. To more effectively eradicate the different persister forms tolerant to doxycycline or amoxicillin, drug combinations were studied using previously identified drugs from an FDA-approved drug library with high activity against such persisters. Using a SYBR Green/PI viability assay, daptomycin-containing drug combinations were the most effective. Of studied drugs, daptomycin was the common element in the most active regimens when combined with doxycycline plus either beta-lactams (cefoperazone or carbenicillin) or an energy inhibitor (clofazimine). Daptomycin plus doxycycline and cefoperazone eradicated the most resistant microcolony form of B. burgdorferi persisters and did not yield viable spirochetes upon subculturing, suggesting durable killing that was not achieved by any other two or three drug combinations. These findings may have implications for improved treatment of Lyme disease, if persistent organisms or detritus are responsible for symptoms that do not resolve with conventional therapy.

The differential diagnosis should include neurological, rheumatic and mental diseases. Till now there is no causative treatment of PLDS. In relieving symptom rehabilitation, painkillers, anti-inflammatory and antidepressants medicines are recommended. Emotional and psychological supports are also necessary. Non-specific symptoms reported by patients with post- Lyme disease syndrome raise the suspicion of other pathologies.

This condition is called post-Lyme disease syndrome (PLDS) or post-treatment Lyme disease syndrome. These two terms are used interchangeably. The pathogenesis of PLDS has been controversial. The hypothesis that patients with PLDS may harbor hidden reservoirs of Borrelia burgdorferi after their initial antibiotic treatment is difficult to accept. The prospective, double-blind studies contradict this point of view. Also, recently published research applying xenodiagnosis to PLDS supports the opinion that PLDS most likely has an autoimmune background. Lengthy courses of antibiotics are not justified in patients with PLDS because of the lack of benefit, and they are fraught with hazards. Most patients with PLDS recover from persistent symptoms with time. However, it can take months before they feel completely well.",

However, despite adequate antibiotic treatment some patients report persisting symptoms which are commonly summarised as post-treatment Lyme disease syndrome (PTLDS). In 2005, the Swiss Society of Infectious Diseases published a case definition for PTLDS. We aimed to review the scientific literature with a special emphasis on the last 10 years, questioning whether the definitions from 2005 are still valid in the light of current knowledge. Furthermore, we describe the clinical history of infection with Borrelia burgdorferi sensu lato, the estimated prevalence of PTLDS, the possible pathogenesis of PTLDS, and treatment options with an emphasis on clinical studies. In summary, we were unable to find a scientific reason for modification of the PTLDS definitions published in 2005. Thus, the diagnostic criteria remain unchanged, namely documented clinical and laboratory evidence of previous infection with B. burgdorferi, a completed course of appropriate antibiotic therapy, symptoms including fatigue, arthralgia, myalgia, cognitive dysfunction or radicular pain persisting for >6 months, a plausible timely association between documented B. burgdorferi infection and onset of symptoms (i.e., persistent or recurrent symptoms that began within 6 months of completion of a recommended antibiotic therapy for early or late Lyme borreliosis), and exclusion of other somatic or psychiatric causes of symptoms. The main therapeutic options remain cognitive behavioural therapy and low-impact aerobic exercise programmes. Growing and unequivocal evidence confirms that prolonged or repeated antibiotic therapy for PTLDS is not beneficial, but potentially harmful and therefore contraindicated. The Guidelines of the Swiss Society of Infectious Diseases offer an evidence based, diagnostic and therapeutic framework for physicians caring for patients suffering from presumptive PTLDS in Switzerland.",

While the cause for this is debated, one possibility is that persister bacteria are not killed by the current Lyme antibiotics and remain active in the system. It has been reported that essential oils have antimicrobial activities and some have been used by patients with persisting Lyme disease symptoms. However, the activity of essential oils against the causative agent Borrelia burgdorferi (B. burgdorferi) has not been well studied. Here, we evaluated the activity of 34 essential oils against B. burgdorferi stationary phase culture as a model for persister bacteria. We found that not all essential oils had activity against the B. burgdorferi stationary phase culture, with top five essential oils (oregano, cinnamon bark, clove bud, citronella, and wintergreen) at a low concentration of 0.25% showing high anti-persister activity that is more active than the known persister drug daptomycin. Interestingly, some highly active essential oils were found to have excellent anti-biofilm ability as shown by their ability to dissolve the aggregated biofilm-like structures. The top three hits, oregano, cinnamon bark, and clove bud completely eradicated all viable cells without any regrowth in subculture in fresh medium, whereas but not citronella and wintergreen did not have this effect. Carvacrol was found to be the most active ingredient of oregano oil showing excellent activity against B. burgdorferi stationary phase cells, while other ingredients of oregano oil p-cymene and \u03b1-terpinene had no apparent activity. Future studies are needed to characterize and optimize the active essential oils in drug combination studies in vitro and in vivo and to address their safety and pharmacokinetic properties before they can be considered as a novel treatment of persistent Lyme disease.",

A retrospective cohort analysis of medical and pharmacy claims derived from the Truven Health Market Scan Commercial Claims and Encounters Database assessed 90-day incidence rates of adverse events (AEs) associated with PLDS treatment (PLDS-Tx). Patients were diagnosed with PLDS \u22656 months after initial diagnosis and standard antibiotic treatment for Lyme disease. Comparison cohorts included intravenous (IV) PLDS-Tx with or without oral antibiotics; oral antibiotic-only PLDS-Tx; or neither. Composite AE incidence rates were higher for patients treated with IV or oral PLDS-Tx than for patients not receiving either treatment (18.7%, 16.8%, and 13.4%, respectively; P = .019). Significant between-group differences in AE incidence rates were noted for electrolyte imbalance (4.0%, 1.5%, and 0.7%, respectively; P = .001) and infection (14.0%, 12.7%, and 9.3%; P = .006). Infection prevalence increased by 22.0% in the IV treatment group and 17.7% in the oral group. Incidence rates for all-cause and AE-related hospital stays and emergency department visits were higher for treated than nontreated patients, particularly when treatment was IV (all P < .01). Of IV-treated patients, 7.3% experienced an incident all-cause inpatient stay and 11.3% an incident all-cause emergency department visit, compared with, respectively, 2.2% and 3.4% of those treated with oral antibiotics and 0.9% and 1.9% of nontreated patients.

This entity has been defined as post-Lyme disease syndrome or post-treatment Lyme disease syndrome. The pathophysiology of this syndrome is unknown, but neither persistence of the bacterium nor effectiveness of antibiotics are currently reported in the literature. The French High Council for Public Health (French acronym HCSP) has recently defined a new entity called \"persistent polymorphic symptoms after a tick bite\" allowing for designing studies to better understand these subjective presentations, for which objective biomarkers are currently lacking. This entity encompasses patients experiencing fatigue and generalized pain in the months following a tick bite and can be associated with several subjective symptoms with major impact on the quality of life.

In recent years, patients' associations and physicians have been supporting the hypothesis that this infection would manifest as chronic generalized musculoskeletal pain symptoms, named \"chronic Lyme disease\". Fibromyalgia is a clinical presentation characterized by chronic generalized musculoskeletal pain with a major impact on quality of life and social and psychological functioning. We analyzed existing literature data on pain syndromes associated with Lyme disease (post-treatment Lyme disease syndrome) or tick bites (polymorphic symptoms after a tick bite). We also analyzed existing data on the diagnosis, pathophysiology, and treatment of fibromyalgia. Our review shows that post-treatment Lyme disease syndrome has characteristics very close to post-infectious fibromyalgia. On the other hand, patients presenting for Lyme disease screening because of chronic generalized musculoskeletal pain symptoms after a tick bite should also be screened for fibromyalgia to allow appropriate management. Antibiotics are not recommended here.",

The cause for PTLDS is unclear and hotly debated. Borrelia burgdorferi develops morphological variants under stress conditions but their significance is not clear. Here we isolated the biofilm-like microcolony (MC) and planktonic (spirochetal form and round body) (SP) variant forms from the stationary phase culture of B. burgdorferi and showed that the MC and SP variant forms were not only more tolerant to the current Lyme antibiotics but also caused more severe arthritis in mice than the log phase spirochete form (LOG). We propose to divide the persistent Lyme disease into two categories: (1) early development of persistent disease from inoculation with persister/biofilm at the beginning of infection introduced by tick bites, or Type I persistent disease (i.e., PTLDS); and (2) late development of persistent disease due to initial infection not being diagnosed or treated in time such that the infection develops into late persistent disease, or Type II persistent disease. Importantly, we show that the murine infection caused by LOG could be eradicated by ceftriaxone whereas the persistent infection established with MC could not be eradicated by doxycycline (Doxy), ceftriaxone (CefT), or vancomycin (Van), or Doxy+CefT or Van+CefT, but could only be eradicated by the persister drug combination daptomycin+doxycycline+ceftriaxone. We conclude that varying levels of persistence and pathologies of Borrelia infection and the corresponding different treatment responses are mostly dictated by the heterogeneous B. burgdorferi variant forms inoculated at the time of tick bites. These findings may have broad implications for understanding pathogenesis and treatment of not only persistent Lyme disease but also other persistent infections in general and call for studies to evaluate if treatment of persistent infections with persister drug combination regimens is more effective than the current mostly single-antibiotic monotherapy.",

We present a case of M. goodii bacteremia with concomitant pulmonary septic emboli that developed in a 32-year-old woman with an indwelling central venous catheter (CVC). The CVC had been placed one year previously for intermittent treatment with intravenous, broadspectrum antibiotics, administered by an outside physician for the treatment of symptoms attributed to chronic Lyme disease. Despite our recommendations, the patient declined follow-up in our Infectious Diseases clinic, opting to continue care under her chronic Lyme disease physician. This case clearly demonstrates the potential for serious medical complications that can arise from the inappropriate use of longterm intravenous antibiotics using a CVC to treat non-specific symptoms attributed to Lyme disease and patients should be counseled regarding these risks.",

The General Symptom Questionnaire (GSQ-30) was developed to fill the need for a brief patient-reported measure of multi-system symptom burden. In this study we assess the psychometric properties and sensitivity to change of the GSQ-30. Materials and Methods: 342 adult participants comprised 4 diagnostic groups: Lyme disease (post-treatment Lyme disease syndrome, n = 124; erythema migrans, n = 94); depression, n = 36; traumatic brain injury, n = 51; healthy, n = 37. Participants were recruited from clinical research facilities in Massachusetts, Maryland, and New York. Validation measures for the GSQ-30 included the Patient Health Questionnaire-4 for depression and anxiety, visual analog scales for fatigue and pain, the Sheehan Disability Scale for functional impairment, and one global health question. To assess sensitivity to change, 53 patients with erythema migrans completed the GSQ-30 before treatment and 6 months after 3 weeks of treatment with doxycycline. Results: The GSQ-30 demonstrated excellent internal consistency (Cronbach \u03b1 = 0.95). The factor structure reflects four core domains: pain/fatigue, neuropsychiatric, neurologic, and viral-like symptoms. Symptom burden was significantly associated with depression (r s = 0.60), anxiety (r s = 0.55), pain (r s = 0.75), fatigue (r s = 0.77), functional impairment (r s = 0.79), and general health (r s = -0.58). The GSQ-30 detected significant change in symptom burden before and after antibiotic therapy; this change correlated with change in functional impairment. The GSQ-30 total score significantly differed for erythema migrans vs. three other groups (post-treatment Lyme disease syndrome, depression, healthy controls). The GSQ-30 total scores for traumatic brain injury and depression were not significantly different from post-treatment Lyme disease syndrome. Conclusions and Relevance: The GSQ-30 is a valid and reliable instrument to assess symptom burden among patients with acute and post-treatment Lyme disease syndrome and is sensitive in the detection of change after treatment among patients with erythema migrans. The GSQ-30 should prove useful in clinical and research settings to assess multi-system symptom burden and to monitor change over time. The GSQ-30 may also prove useful in future precision medicine studies as a clinical measure to correlate with disease-relevant biomarkers.",
        "31888310": "ID: 31888310\nTitle: Chronic Lyme Disease: An Evidence-Based Definition by the ILADS Working Group.\nAbstract: Objective: Chronic Lyme disease has been a poorly defined term and often dismissed as a fictitious entity. In this paper, the International Lyme and Associated Diseases Society (ILADS) provides its evidence-based definition of chronic Lyme disease. Definition: ILADS defines chronic Lyme disease (CLD) as a multisystem illness with a wide range of symptoms and/or signs that are either continuously or intermittently present for a minimum of six months. The illness is the result of an active and ongoing infection by any of several pathogenic members of the Borrelia burgdorferi sensu lato complex (Bbsl). The infection has variable latency periods and signs and symptoms may wax, wane and migrate. CLD has two subcategories, CLD, untreated (CLD-U) and CLD, previously treated (CLD-PT). The latter requires that CLD manifestations persist or recur following treatment and are present continuously or in a relapsing/remitting pattern for a duration of six months or more. Methods: Systematic review of over 250 peer reviewed papers in the international literature to characterize the clinical spectrum of CLD-U and CLD-PT. Conclusion: This evidence-based definition of chronic Lyme disease clarifies the term's meaning and the literature review validates that chronic and ongoing Bbsl infections can result in chronic disease. Use of this CLD definition will promote a better understanding of the infection and facilitate future research of this infection.",

It usually begins with erythema migrans; early disseminated infection particularly causes multiple erythema migrans or neurologic disease, and late manifestations predominantly include arthritis in North America, and acrodermatitis chronica atrophicans (ACA) in Europe. Diagnosis of Lyme borreliosis is based on characteristic clinical signs and symptoms, complemented by serological confirmation of infection once an antibody response has been mounted. Manifestations usually respond to appropriate antibiotic regimens, but the disease can be followed by sequelae, such as immune arthritis or residual damage to affected tissues. A subset of individuals reports persistent symptoms, including fatigue, pain, arthralgia, and neurocognitive symptoms, which in some people are severe enough to fulfil the criteria for post-treatment Lyme disease syndrome. The reported prevalence of such persistent symptoms following antimicrobial treatment varies considerably, and its pathophysiology is unclear. Persistent active infection in humans has not been identified as a cause of this syndrome, and randomized treatment trials have invariably failed to show any benefit of prolonged antibiotic treatment. For prevention of Lyme borreliosis, post-exposure prophylaxis may be indicated in specific cases, and novel vaccine strategies are under development.",

At the completion of therapy, all three patients' major Lyme symptoms remained in remission for a period of 25-30 months. A retrospective chart review of 37 additional patients undergoing DDD CT therapy (40 patients in total) was also performed, which demonstrated tick-borne symptom improvements in 98% of patients, with 45% remaining in remission for 1 year or longer. In conclusion, double-dose dapsone therapy could represent a novel and effective anti-infective strategy in chronic Lyme disease/ post-treatment Lyme disease syndrome (PTLDS), especially in those individuals who have failed regular dose dapsone combination therapy (DDS CT) or standard antibiotic protocols.

The aim of this prospective cohort study was to evaluate diagnostic outcome and to characterize demographics and clinical presentations of patients referred between the 1st of September 2017 to 31st of August 2019. A diagnosis of Lyme borreliosis was based on medical history, symptoms, serology and cerebrospinal fluid analysis. The patients were classified as definite Lyme borreliosis, possible Lyme borreliosis or post-treatment Lyme disease syndrome. Antibiotic treatment of Lyme borreliosis manifestations was initiated in accordance with the national guidelines. Patients not fulfilling the criteria of Lyme borreliosis were further investigated and discussed with an interdisciplinary team consisting of specialists from relevant specialties, according to individual clinical presentation and symptoms. Clinical information and demographics were registered and managed in a database. A total of 215 patients were included in the study period. Median age was 51 years (range 17-83 years), and 56 % were female. Definite Lyme borreliosis was diagnosed in 45 patients, of which 20 patients had erythema migrans, 14 patients had definite Lyme neuroborreliosis, six had acrodermatitis chronica atrophicans, four had multiple erythema migrans and one had Lyme carditis. Furthermore, 12 patients were classified as possible Lyme borreliosis and 12 patients as post-treatment Lyme disease syndrome. A total of 146 patients (68 %) did not fulfil the diagnostic criteria of Lyme borreliosis. Half of these patients (73 patients, 34 %) were diagnosed with an alternative diagnosis including inflammatory diseases, cancer diseases and two patients with a tick-associated disease other than Lyme borreliosis. A total of 73 patients (34 %) were discharged without sign of somatic disease. Lyme borreliosis patients had a shorter duration of symptoms prior to the first hospital encounter compared to patients discharged without a specific diagnosis (p<0.001). When comparing symptoms at presentation, patients discharged without a specific diagnosis suffered more often from general fatigue and cognitive dysfunction. In conclusion, 66 % of all referred patients were given a specific diagnosis after ended outpatient course. A total of 32 % was diagnosed with either definite Lyme borreliosis, possible Lyme borreliosis or post-treatment Lyme disease syndrome; 34 % was diagnosed with a non-tick-associated diagnosis.

Targeted pathogens were Borrelia, Babesia, Anaplasma, Rickettsia, Ehrlichia, Bartonella, Francisella, Powassan virus, tick-borne encephalitis virus, and Colorado tick fever virus. Specificity was defined by 100% amino acid sequence identity with tick-borne pathogen proteins, evolutionary taxonomic verification for related pathogens, and no identity with human or other organisms. Using a cut off of two pathogen peptides, 9/10 acute Lyme Borreliosis patients resulted positive, while we identified zero false positive in 250 controls.

We evaluated whether Swedish adults who met the criteria for post-treatment Lyme disease syndrome (PTLDS) exhibited characteristics distinguishable from adults who did not, but who displayed similar symptoms and disease course after suspected previous tick-bite infection (TBI). During 2015-2018, 255 patients-referred to the Centre for Vector-borne Infections, Uppsala University Hospital, Sweden with symptoms lasting longer than six months-were recruited. Of this group, 224 completed the study. Each patient was examined by an infectious disease specialist and, besides a full medical history, underwent a panel of blood and cerebrospinal fluid laboratory tests including hematological, biochemical, microbiological and immunological analyses, and the RAND-36 scale to measure quality of life. For analysis purposes, patients were divided into five subgroups, of which one represented PTLDS. According to serological results indicating TBI and documented/ reported objective signs of Lyme disease, 85 (38%) patients fulfilled the criteria for PTLDS and were compared with the other 139 (62%) serologically classified patients. In the PTLDS group, erythema chronicum migrans (ECM) was documented/reported in 86% of patients, previous neuroborreliosis in 15%, and acrodermatitis chronica atroficans (ACA) in 3.5%. However, there were no significant differences regarding symptoms, laboratory results or disease course between patients with PTLDS and those without laboratory evidence of Borrelia exposition. Most reported symptoms were fatigue-related (70%), musculoskeletal (79%), neurological (82%) and neurocognitive (57%). Tick bites were recalled by 74%. The RAND-36 score was significantly below that of the general Swedish population. Signs of immunological/inflammatory reactivity with myositis antibodies were detected in 20% of patients, fibrinogen levels were moderately increased in 21% and elevated rheumatoid factor in 6%. The PTLDS group did not differ exclusively in any respect from the other subgroups, which either lacked previously documented/reported evidence of borreliosis or even lacked detectable serological signs of exposure to Lyme disease. The results suggest that symptoms often categorized as Chronic-Lyme-Disease (CLD) in the general debate, cannot be uniquely linked to Lyme disease. However, approximately 20% of the total group of patients showed signs of autoimmunity. Further studies are needed to elucidate the underlying causes and mechanisms of PTLDS and there is reason to consider a multifactorial approach.",

The aim of this review is to identify comprehensive treatment strategies for PTLDS patients. Unfortunately, universal guidelines for diagnosing and treating PTLDS do not currently exist. Consequently, physicians cannot adequately address concerns of possible PTLDS patients. Patients are left suffering and searching for answers, and their activities of daily living and quality of life are adversely impacted. This review highlights that PTLDS clinical trials have focused mainly on treatment with antibiotics, yielding challenging results that lack consistency in inclusion criteria across trials. It will remain exceedingly difficult to extrapolate the outcomes of such studies if a standard for PTLDS diagnosis is not well-established. By focusing on treatment trials rather than establishing diagnostic criteria, research in this field ignores a critical step in investigating PTLDS.

The objective of this study was to develop a microsimulation model to estimate the population-level health burden of Lyme disease in Ontario, Canada. We developed a Lyme disease history model using microsimulation, simulating 100 000 people (mean age 37.6 yr, 51% female) from 2017 in Ontario over a lifetime risk of infection and time horizon. We extracted the sensitivity and specificity of the 2-tier testing recommended by the Canadian Public Health Laboratory Network, probabilities and health state utility values from the published literature and health administrative data. Our reported outcomes from our stochastic analysis include diagnosed cases of Lyme disease (stratified by stage), undiagnosed infections, sequelae, individuals with PTLDS and quality-adjusted life-years (QALYs) lost. Our model estimated 333 (95% confidence interval [CI] 329-337) infections over the lifetime of 100 000 simulated people (mean age 37.6 yr, 51% female), with 92% (95% CI 91%-93%) of infections diagnosed. Of those 308 people with Lyme Disease diagnoses, 67 (95% CI 65-69) developed sequelae (e.g., arthritic, cardiac, neurologic sequelae), and 34 (95% CI 33-35) developed PTLDS. Lyme disease resulted in a loss of 84.5 QALYs (95% CI 82.9-86.2) over the lifetime of the simulated cohort. Sensitivity and scenario analysis showed that increasing incidence rates of Lyme disease, potential underreporting, duration of PTLDS and quality of life (health state utility) associated with PTLDS had the greatest impact on health burden. Lyme disease contributes considerable health burden in terms of QALYs lost. Our analysis provides evidence to understand the disease burden and lays the foundation to assess the cost-effectiveness of pharmaceutical and nonpharmaceutical interventions.",

Serum samples from 103 patients with suspected post-treatment Lyme disease syndrome were tested for the presence of antibodies to the major tick-borne pathogens Anaplasma phagocytophilum, Bartonella henselae/Bartonella quinatana, and Babesia microti. Although the presence of anti-Anaplasma antibodies was detected in 12.6% of the samples and anti-Bartonella antibodies in 9.7% of the samples, the presence of antibodies against both pathogens in the same samples or anti-Babesia antibodies in the selected group of patients could not be confirmed. However, we were able to detect autoantibodies, mostly antinuclear, in 11.6% of the patients studied. Our results are in good agreement with previously published studies showing the presence of a wide spectrum of autoantibodies in some patients with complicated forms of Lyme disease and post-treatment Lyme disease syndrome, but they do not reveal a significant influence of co-infections on the development of PTLDS in the studied group of patients.",

Brain PET scan of patients with PTLDS have demonstrated likely glial activation indicating persistent neuroinflammatory processes. It is possible that unresolved bacterial remnants can continue to cause neuroinflammation. In previous studies, we have shown that non-viable Borrelia burgdorferi can induce neuroinflammation and apoptosis in an oligodendrocyte cell line. In this follow-up study, we analyze the effect of sonicated remnants of B. burgdorferi on primary rhesus frontal cortex (FC) and dorsal root ganglion (DRG) explants. Five FC and three DRG tissue fragments from rhesus macaques were exposed to sonicated B. burgdorferi and analyzed for 26 inflammatory mediators. Live bacteria and medium alone served as positive and negative control, respectively. Tissues were also analyzed for cell types mediating inflammation and overall apoptotic changes. Non-viable B. burgdorferi induced significant levels of several inflammatory mediators in both FC and DRG, similar to live bacteria. However, the levels induced by non-viable B. burgdorferi was often (several fold) higher than those induced by live ones, especially for IL-6, CXCL8 and CCL2. This effect was also more profound in the FC than in the DRG. Although the levels often differed, both live and dead fragments induced the same mediators, with significant overlap between FC and DRG. In the FC, immunohistochemical staining for several inflammatory mediators showed the presence of multiple mediators in astrocytes, followed by microglia and oligodendrocytes, in response to bacterial remnants. Staining was also seen in endothelial cells. In the DRG, chemokine/cytokine staining was predominantly seen in S100 positive (glial) cells. B. burgdorferi remnants also induced significant levels of apoptosis in both the FC and DRG. Apoptosis was confined to S100\u2009+\u2009cells in the DRG while distinct neuronal apoptosis was also detected in most FC tissues in response to sonicated bacteria. Non-viable B. burgdorferi can continue to be neuropathogenic to both CNS and PNS tissues with effects likely more profound in the former. Persistence of remnant-induced neuroinflammatory processes can lead to long term health consequences.",

The primary aim of this study was to assess whether participants with a history of Lyme disease (LD) would be more likely to meet criteria for PTLD than those without a history of LD. We conducted a longitudinal, prospective study among 234 participants with and 49 participants without prior LD. All completed survey metrics for fatigue, pain, sleep, depression, and quality of life. An operationalized PTLD definition was applied to both cohorts, and the distributions of clinical outcomes and symptoms were examined. In total, 13\u00b77% of participants with a history of prior LD met criteria for PTLD compared with 4\u00b71% of those without a history of prior LD. Participants with prior LD were approximately 5\u00b728 times as likely to meet PTLD criteria compared with those without prior LD (p\u00a0=\u00a00\u00b7042) and had 8-15 times as high odds of reporting moderate or severe fatigue and muscle pain (p\u00a0=\u00a00\u00b7002, 0\u00b7047, respectively).

Because patients with a suspicion of Lyme borreliosis (LB) may have experienced difficult care paths, the Tick-Borne Diseases Reference Center (TBD-RC) was started in 2017. The aim of our study was to compare the clinical features of patients according to their final diagnoses, and to determine the factors associated with recovery in the context of multidisciplinary management for suspected LB. Methods. We included all adult patients who were seen at the TBD-RC (2017-2020). Four groups were defined: (i) confirmed LB, (ii) possible LB, (iii) Post-Treatment Lyme Disease Syndrome (PTLDS) or sequelae, and (iv) other diagnoses. Their clinical evolution at 3, 6, and 9-12 months after care was compared. Factors associated with recovery at 3 and at 9-12 months were identified using logistic regression models. Results. Among the 569 patients who consulted, 72 (12.6%) had confirmed LB, 43 (7.6%) possible LB, 58 (10.2%) PTLDS/sequelae, and 396 (69.2%) another diagnosis. A favorable evolution was observed in 389/569 (68.4%) at three months and in 459/569 (80.7%) at 12 months, independent of the final diagnosis. A longer delay between the first symptoms and the first consultation at the TBD-RC (p = 0.001), the multiplicity of the diagnoses (p = 0.004), and the inappropriate prescription of long-term antibiotic therapy (p = 0.023) were negatively associated with recovery, reflecting serial misdiagnoses. Conclusions. A multidisciplinary team dedicated to suspicion of LB may achieve a more precise diagnosis and better patient-centered medical support in the adapted clinical sector with a shorter delay, enabling clinical improvement and avoiding inappropriate antimicrobial prescription.",

We aimed to describe the management and clinical course of Lyme disease in patients treated in acute care facilities in Quebec and to assess adherence to the 2006 Infectious Diseases Society of America (IDSA) guideline. This retrospective multicentre cohort study included pediatric and adult patients with serologically confirmed Lyme disease treated in acute care facilities (12 community hospitals and 2 tertiary care centres) of 2 endemic regions of Quebec (Estrie and Mont\u00e9r\u00e9gie), from 2004 to 2017. We considered drug choice, prescribed dose and treatment duration in assessing adherence of prescriptions to the 2006 IDSA guideline. The main outcome was complete resolution of symptoms at 3 months after the initiation of treatment. We included 272 patients from 14 institutions (age range 3-87 yr). Early disseminated Lyme disease (140 patients [51%]) was predominant. Adherence to the IDSA guideline was observed in 235 (90%) of the 261 cases with complete information, and adherence was stable over time (2004-2013: 57/64 [89%]; 2014-2015: 64/71 [90%]; 2016-2017: 114/126 [90%]; p = 0.8). Non-adherence to the guideline (n = 26) was predominantly due to longer-than-recommended treatment duration (16/26 [62%]). Resolution of objective signs at 3 months after treatment initiation occurred in 265 (99%) of 267 patients, whereas post-treatment Lyme disease syndrome was observed in 27 patients (10%) with increasing incidence over time (2004-2013: 3/65 [5%]; 2014-2015: 4/73 [5%]; 2016-2017: 20/129 [16%]; p = 0.02). We observed clinical resolution of Lyme disease in 99% of the patients, and most treatments (90%) complied with the 2006 IDSA guideline.

A seven- to eight-week protocol of double dose dapsone combination therapy (DDDCT) for CLD/PTLDS results in symptom remission in approximately 50% of patients for one year or longer, with published culture studies indicating higher doses of dapsone demonstrate efficacy against resistant biofilm forms of Borrelia burgdorferi. The purpose of this study was, therefore, to evaluate higher doses of dapsone in the treatment of resistant CLD/PTLDS and associated co-infections. A total of 25 patients with a history of Lyme and associated co-infections, most of whom had ongoing symptoms despite several courses of DDDCT, took one or more courses of high dose pulsed dapsone combination therapy (200 mg dapsone \u00d7 3-4 days and/or 200 mg BID \u00d7 4 days), depending on persistent symptoms. The majority of patients noticed sustained improvement in eight major Lyme symptoms, including fatigue, pain, headaches, neuropathy, insomnia, cognition, and sweating, where dapsone dosage, not just the treatment length, positively affected outcomes. High dose pulsed dapsone combination therapy may represent a novel therapeutic approach for the treatment of resistant CLD/PTLDS, and should be confirmed in randomized, controlled clinical trials.",

Participants were randomly assigned to 8 weeks of a KY small-group intervention or a waitlist control (WLC). Adherence was measured as attendance at KY group sessions. Primary outcomes assessed pain, pain interference, fatigue, and global health. Secondary outcomes assessed multisystem symptom burden, mood, sleep, physical and social functioning, cognition, and mindfulness. Linear mixed models were used to test changes in outcomes over time as a function of group assignment; intercepts for participants were modeled as random effects. Although the target sample size was 40 participants, the study concluded with 29 participants due to recruitment challenges. No KY participants dropped out of the study, and participants attended 75% of group sessions on average, but WLC retention was poor (57%). Regarding primary outcomes, there was no significant interaction between group and time. Regarding secondary outcomes, there was a significant interaction between group and time for multisystem symptom burden (p < 0.05) and cognition (p < 0.01); KY participants reported improved multisystem symptom burden and cognition over the course of the study compared to WLC participants. To enhance recruitment and retention, future trials may consider expanding geographic access and including supportive procedures for WLC participants. This preliminary study supports the need for a larger study to determine if KY reduces multisystem symptom burden and enhances cognition among people with PTLDS.",

When present for more than 6\u00a0months and causing a reduction in daily activities, this is often referred to as post-treatment Lyme disease syndrome (PTLDS). This study aimed to compare the occurrence of symptoms between LB patients and controls, to estimate the proportion of LB patients developing PTLDS and to identify risk factors. A prospective cohort study was set up including three subpopulations: patients with an erythema migrans (EM) (i) or disseminated/late LB (ii) and a non-LB control group (iii). At 6- and 12-months follow-up, the occurrence of several symptoms, including six symptoms used to define PTLDS, i.e. muscle pain, joint pain, fatigue, memory problems, difficulties concentrating and problems finding words, and impact on daily activities, was compared between LB patients and controls. Finally, the proportion of LB patients developing PTLDS as defined by the Infectious Disease Society of America was estimated, including a time frame for symptoms to be present. Although the risk of presenting PTLDS-related symptoms was significantly higher in EM patients (n\u2009=\u2009120) compared to controls (n\u2009=\u2009128) at 6\u00a0months follow-up, the risk of presenting at least one of these symptoms combined with impact on daily activities was not significantly higher in EM patients, at either 6- or 12-months follow-up. A significant association was found between disseminated/late LB (n\u2009=\u200915) and the occurrence of any PTLDS-symptom with an impact on daily activities at both time points. The proportion of patients with PTLDS was estimated at 5.9% (95% CI 2.7-12.9) in EM patients and 20.9% (95% CI 6.8-64.4) in patients with disseminated/late LB (RR\u2009=\u20093.53, 95% CI 0.98-12.68, p\u2009=\u20090.053). No significant risk factors were identified, which may be explained by small sample sizes. In our study, PTLDS was present in both LB cohorts, yet with a higher percentage in disseminated/late LB patients. Additional research is needed into risk factors for and causes of this syndrome. In addition, development and validation of standardized methods to assess the PTLDS case definition, easily applicable in practice, is of great importance.",

The aim of this exploratory study was to evaluate the feasibility of protein biomarker profiling as a diagnostic platform for this category of patients and to compare these results with similarly obtained results from a group of patients with acute neuroborreliosis. Two groups of patient cohorts (Cohort 1 and 2) were analyzed for biomarkers in serum and cerebrospinal fluid (CSF); the results were used for group-level comparison. Cohort 1 comprised 158 adult patients selected from 224 previously diagnosed patients, who between October 2015 and December 2018, after referral, were enrolled and structurally investigated based on defined inclusion criteria. They displayed similar lingering symptoms, with a duration of at least 6 months, after presumed previous tick-borne infection (TBI) and are fully described in a previously published study originating from the Center for Vector-borne Infections (CVI), Uppsala University Hospital, Sweden. Cohort 2, comprised 30 patients diagnosed at Uppsala University Hospital between 2016 and 2019 with laboratory-confirmed acute neuroborreliosis. Their proteomic results, based on serum and CSF analyses, were compared with the 158 patients in Cohort 1. The expression and the concentration of potential biomarkers in each patient's serum and CSF samples were measured based on two multiplex protein panels enabling simultaneous analysis of 92 inflammatory and neurology biomarkers. The PTLDS patient subgroup showed no nominally significant proteins compared to the other CVI patients in Cohort 1. However, CVI patients with signs of inflammation, which were evenly distributed in Cohort 1, showed 16 significantly (p <0.05) different proteins in both CSF and serum, but no association was seen with laboratory-confirmed exposure to Borrelia spp or other TBIs. When comparing the two cohorts, different protein profiles were observed, with 125/148 significantly different proteins in CSF and 93/174 in serum, in patients with laboratory confirmed acute neuroborreliosis, of which 6 in CSF and 6 in serum were significant at the p <0.001 level. In this first comprehensive inflammatory and neurological biomarker profile study no differences in biomarker profiles were detected between patients with PTLDS and patients with similar persisting symptoms but who did not meet the PTLDS criteria, regardless of whether laboratory verified previous exposure to Borrelia or other TBI's were present. However, the expressed markers differed from those found in patients with confirmed acute neuroborreliosis, which does not support the view that PTLDS reflects an ongoing Borrelia infection. Further studies are needed to understand and assess the usefulness of biosignatures of patients with PTLDS before they can be applied in a clinical setting.",

Persisting symptoms are often termed post-Lyme disease syndrome, of which etiology is not clearly understood. The aim of this study was to investigate cognitive function, possible structural changes in brain regions and level of fatigue. We have not found previous studies on neuroborreliosis that use standardized neuropsychological tests and MRI with advanced image processing to investigate if there are subtle regional changes in cortical thickness and brain volumes after treatment. We examined 68 patients treated for neuroborreliosis 6\u00a0months earlier and 66 healthy controls, with a comprehensive neuropsychological test protocol, quantitative structural MRI analysis of the brain and Fatigue Severity Scale. We found no differences between the groups in either cognitive function, cortical thickness or brain volumes. The patients had higher score on Fatigue Severity Scale 3.8 vs. 2.9 (p\u2009=\u20090.001), and more patients (25.4%) than controls (5%) had severe fatigue (p\u2009=\u20090.002), but neither mean score nor proportion of patients with severe fatigue differed from findings in the general Norwegian population.

This study aimed to estimate the economic cost associated with the different clinical manifestations of LB in Belgium. An incidence approach and societal perspective were used to estimate the total cost-of-illness for LB in Belgium. Costs were calculated for patients with erythema migrans (EM) or disseminated/late LB, including patients who developed post-treatment Lyme disease syndrome (PTLDS). Direct medical, direct non-medical (transportation & paid help) and indirect non-medical costs (productivity losses) were included in the analysis. Ambulatory cost data were collected through a prospective cohort study from June 2016 to March 2020, in which patients with LB were followed up 6 to 12\u00a0months after diagnosis. Hospitalization costs were retrieved from the Minimal Clinical Data registry, a mandatory registry for all Belgian hospitals, linked to the Minimal Financial Data registry. Costs were expressed in 2019 euros. The total annual cost associated with clinical manifestations of LB in Belgium was estimated at \u20ac5.59 million (95% UI 3.82-7.98). Of these, \u20ac3.44 million (95% UI 2.05-5.48) or 62% was related to disseminated/late LB diagnoses and \u20ac2.15 million (95% UI 1.30-3.26) to EM. In general, direct medical costs and productivity losses accounted for 49.8% and 46.4% of the total costs, respectively, while direct non-medical costs accounted for only 3.8%. The estimated mean costs were \u20ac193 per EM patient and \u20ac5,148 per disseminated/late LB patient. While patients with PTLDS seemed to have somewhat higher costs compared to patients without PTLDS, the number of patients was too small to have representative estimates. We estimate the total annual direct medical costs, direct non-medical and indirect non-medical costs associated with LB to exceed \u20ac5.5 million per year, almost evenly distributed between EM (40%) and disseminated/late LB (60%). EM costs 26 times less per patient but occurs also 16 times more frequently than disseminated/late LB. The cost burden remains limited by comparison to other infectious diseases due to the relative lower incidence.",

The term post-treatment Lyme disease syndrome (PTLDS) is currently used for this condition in scientific literature. The pathogenesis is still not precisely known, but the involvement of immunopathological mechanisms is assumed. In our study, we analyzed the presence of autoantibodies including myositis-specific (MSA) and myositis-associated autoantibodies (MAA) in patients with laboratory proven history of Lyme disease and with clinical symptoms of PTLDS. A total of 59 patients meeting the criteria for PTLDS were enrolled in this study. The control group consisted of 40 patients undergoing differential diagnosis of neurological disorders without clinical and/or laboratory-proven history of Lyme disease. The presence of autoantibodies was determined by immunoblot methods and positive samples were further tested for serum creatine kinase (CK) and myoglobin levels. The presence of myositis autoantibodies was detected in 18 subjects with suspected PTLDS (30.5%), but only in 5% of control subjects exhibiting no evidence of Lyme disease history. The difference was statistically significant (p = 0.002). The subsequent biochemical analysis of muscle-damage markers in positive subjects found a mild elevation in six MSA/MAA-positive PTLDS patients.

Currently, little is known about the cause or epidemiology of PTLDS. We conducted a data-driven study with a large nationwide administrative dataset, which consists of more than 98 billion billing and 1.4 billion prescription records between 2008 and 2016, to identify unique aspects of PTLDS that could have diagnostic and etiologic values. We defined PTLDS based on its symptomatology and compared the demographic, longitudinal changes of comorbidity, and antibiotic prescriptions between patients who have Lyme with absence of prolonged symptoms (APS) and PTLDS. The age and temporal distributions were similar between Lyme APS and PTLDS. The PTLDS-to-Lyme APS case ratio was 3.42%. The co-occurrence of 3 out of 19 chronic conditions were significantly higher in PTLDS versus Lyme APS-odds ratio and 95% CI for anemia, hyperlipidemia, and osteoarthrosis were 1.46 (1.11-1.92), 1.39 (1.15-1.68), and 1.62 (1.23-2.12) respectively.

PTLDS cases have more codes corresponding to anemia, hyperlipidemia, and osteoarthrosis compared to Lyme APS.

Consensus on guidance regarding diagnosis and treatment is currently lacking. Consequently, patients suffer and are left searching for answers, negatively impacting their quality of life and healthcare expenditure. Yet, health economic data on PTLDS remain scarce. The aim of this article is therefore to assess the cost-of-illness related to PTLDS, including the patient perspective. PTLDS patients (N\u2009=\u2009187) with confirmed diagnosis of LB were recruited by a patient organization. Patients completed a self-reported questionnaire on LB-related healthcare utilization, absence from work and unemployment. Unit costs (reference year 2018) were obtained from national databases and published literature. Mean costs and uncertainty intervals were calculated via bootstrapping. Data were extrapolated to the Belgian population. Generalized linear models were used to determine associated covariates with total direct costs and out-of-pocket expenditures. Mean annual direct costs amounted to \u20ac4618 (95% CI \u20ac4070-5152), of which 49.5% were out-of-pocket expenditures.

Patients who attribute chronic symptoms to Lyme disease commonly use herbal supplements. The complexity, variability in dose and formulation, and lack of data for these herbal compounds make it difficult to assess their efficacy and safety. This review examines the evidence for the antimicrobial activity, safety, and drug-drug interactions of 18 herbal supplements that patients commonly use for treatment of persistent symptoms attributed to Lyme disease.

The search used the keywords for 18 herbal compounds: (1) andrographis (Andrographis paniculate), (2) astragalus (Astragalus propinquus), (3) berberine, (4) cat's claw bark (Uncaria tomentosa), (5) cordyceps (Cordyceps sinensis), (6) cryptolepis (Cryptolepis sanguinolenta), (7) Chinese skullcap (Scutellaria baicalensis), (8) garlic (Allium sativum), (9) Japanese knotwood (Polygonum cuspidatum), (10) reishi mushrooms (Ganoderma lucidum), (11) sarsaparilla (Smilax medica), (12) Siberian ginseng (Eleutherococcus senticosus), (13) sweet wormwood (Artemisia annua), (14) teasle root (Dipsacus fullonum), (15) lemon balm (Melissa officinalis), (16) oil of oregano (Origanum vulgare), (17) peppermint (Mentha x piperita), and (18) thyme (Thymus vulgaris). The team also searched for terms related to protocols, including Dr. Rawls' protocol and the Buhner protocol. University of Maryland Medical Center, Baltimore MD. Seven of the 18 herbs reviewed had evidence for in-vitro activity against B. burgdorferi. These compounds included: (1) cat's claw (2) cryptolepis, (3) Chinese skullcap, (4) Japanese knotweed, (5) sweet wormwood, (6) thyme, and (7) oil of oregano. With the exception of oil of oregano these compounds also have anti-inflammatory activity. In vivo data and clinical trials are lacking. Clinicians should be cautious as many of the identified compounds have drug interactions and additive effects that could lead to increased risks for bleeding, hypotension, and hypoglycemia. Many of the herbs that alternative and integrative practitioners use to treat Lyme disease have anti-inflammatory effects that may contribute to patients' perceptions of symptomatic improvement. Some herbs have limited demonstrated anti-borrelial activity in vitro, but in-vivo data and clinical trial data is lacking. Further research is required to determine the efficacy, safety and appropriate use of these herbs for this patient population.",

Although most cases of LB can be cured with a course of antibiotics, some children can present prolonged symptoms, which may constitute post-treatment Lyme disease syndrome (PTLDS). The aim of our analysis was the long-term observation of children with NB and the determination of their risk of PTLDS. The clinical observation was supplemented by a laboratory study based on the assessment of the dynamics of anti-VlsE (variable major protein-like sequence, expressed) IgG antibodies in children with NB after antibiotic therapy. The prospective survey based on 40 children presented 1-2 forms of NB. The control group consisted of 36 patients with analogical symptoms for whom LB was excluded. Our long-term observation showed a low risk of developing long-term complications in children who received antibiotic therapy in accordance with the recommendations. The concentration of anti-VlsE IgG demonstrates a statistical significance for differences between the control and the study groups for each measurement period. Higher values of anti-VlsE IgG were observed in the study group, and the concentration decreased from the first measurement period to the next. The article emphasizes the importance of the long-term follow-up of children with neuroborreliosis.",

Many aspects of the disease are still topics of controversy within the scientific and medical communities. One particular point of debate is the etiology behind antibiotic treatment failure of a significant portion (10-30%) of Lyme disease patients. The condition in which patients with Lyme disease continue to experience a variety of symptoms months to years after the recommended antibiotic treatment is most recently referred to in the literature as post treatment Lyme disease syndrome (PTLDS) or just simply post treatment Lyme disease (PTLD). The most commonly proposed mechanisms behind treatment failure include host autoimmune responses, long-term sequelae from the initial Borrelia infection, and persistence of the spirochete. The aims of this review will focus on the in vitro, in vivo, and clinical evidence that either validates or challenges these mechanisms, particularly with regard to the role of the immune response in disease and resolution of the infection. Next generation treatments and research into identifying biomarkers to predict treatment responses and outcomes for Lyme disease patients are also discussed. It is essential that definitions and guidelines for Lyme disease evolve with the research to translate diagnostic and therapeutic advances to patient care.",

The Need for Sex-Disaggregated Data in Persistent Illness.\nAbstract: Biological sex should be included as an important variable in clinical research studies to identify outcome differences between men and women. Very few Lyme disease studies were designed to consider sex-based differences or gender bias as an important component of the research design. To assess sex-based differences in Lyme disease patients who were clinically diagnosed and reported remaining ill for six or more months after receiving antibiotic treatment, we analyzed self-reported clinical data from 2170 patients in the MyLymeData patient registry. We also reviewed previous Lyme disease studies for distribution of patients by biological sex according to stage of illness, data source, and definition of disease used as enrollment criteria. In MyLymeData, women reported more tick-borne coinfections, worse symptoms, longer diagnostic delays, more misdiagnoses, and worse functional impairment than men. No differences were reported in antibiotic treatment response or side effects. In our review, of clinical research trials and data sources, we identified a smaller percentage of women in studies of acute Lyme disease and a larger percentage of women in studies of persistent illness. Samples and data sources that were more reflective of patients seen in clinical practice had a higher percentage of women than randomized controlled trials and post-treatment Lyme disease studies. Our results indicate that biological sex should be integrated into Lyme disease research as a distinct variable. Future Lyme disease studies should include sex-based disaggregated data to illuminate differences that may exist between men and women with persistent illness.",

Diagnosis of ME/CFS remains challenging, with most patients relying on self-report, questionnaires, and subjective measures to receive a diagnosis, and many never receiving a clear diagnosis at all. In this study, a single-cell Raman platform and artificial intelligence are utilized to analyze blood cells from 98 human subjects, including 61 ME/CFS patients of varying disease severity and 37 healthy and disease controls. These results demonstrate that Raman profiles of blood cells can distinguish between healthy individuals, disease controls, and ME/CFS patients with high accuracy (91%), and can further differentiate between mild, moderate, and severe ME/CFS patients (84%). Additionally, specific Raman peaks that correlate with ME/CFS phenotypes and have the potential to provide insights into biological changes and support the development of new therapeutics are identified. This study presents a promising approach for aiding in the diagnosis and management of ME/CFS and can be extended to other unexplained chronic diseases such as long COVID and post-treatment Lyme disease syndrome, which share many of the same symptoms as ME/CFS.",

The presentation, pathophysiology, and epidemiology of Lyme disease have been well studied, and thus treatments for this disease are widely available. While the treatment of its early and late stages is relatively simple with 10-14 day and four-week courses of doxycycline, respectively, the main problem rests in the understanding of the etiology and pathology of post-treatment Lyme disease syndrome (PTLDS). With the time of symptoms onsetting approximately six months after treatment and potentially lasting indefinitely, this syndrome's effect on patients' quality of life could be devastating.

        "37727539": "ID: 37727539\nTitle: Lyme Disease: An Overview.\nAbstract: Lyme disease, a tick-borne multisystem disease, is caused by spirochete Borrelia burgdorferi (sensu lato). It is a common illness in temperate countries, especially the United States, but the incidence is increasing across continents due to increasing reforestation, travel and adventure tourism, increased intrusion in the vector habitat, and changing habitat of the vector. Transmission primarily occurs via bite of an infected tick (Ixodes spp.). The appearance of an erythema migrans rash following a tick bite is diagnostic of early Lyme disease even without laboratory evidence. Borrelia lymphocytoma and acrodermatitis chronica atrophicans along with multisystem involvement occur in late disseminated and chronic stages. A two-step serologic testing protocol using an enzyme-linked immunosorbent assay (ELISA) followed by confirmation of positive and equivocal results by Western immunoblot is recommended for the diagnosis. Transplacental transmission to infant occurs in the first trimester with possible congenital Lyme disease making treatment imperative during antenatal period. The treatment is most effective in the early stages of the disease, whereas rheumatological, neurological, or other late manifestations remain difficult to treat with antibiotics alone. Treatment with oral doxycycline is preferred for its additional activity against other tick-borne illnesses which may occur concurrently in 10%-15% of cases. New-generation cephalosporins and azithromycin are alternative options in patients with doxycycline contraindications. No vaccine is available and one episode of the disease will not confer life-long immunity; thus, preventive measures remain a priority. The concept of post-Lyme disease syndrome versus chronic Lyme disease remains contested for want of robust evidence favoring benefits of prolonged antibiotic therapy.",

While most patients with acute Lyme disease recover completely if treated with antibiotics shortly after the onset of infection, approximately 10-30% experience post-treatment symptoms and 5-10% have residual symptoms with functional impairment (post-treatment Lyme disease syndrome or PTLDS). These patients typically experience pain, cognitive problems, and/or fatigue. This narrative review provides a broad overview of Lyme disease, focusing on neuropsychiatric manifestations and persistent symptoms. While the etiology of persistent symptoms remains incompletely understood, potential explanations include persistent infection, altered neural activation, and immune dysregulation. Widely recognized is that new treatment options are needed for people who have symptoms that persist despite prior antibiotic therapy. After a brief discussion of treatment approaches, the article focuses on vagus nerve stimulation (VNS), a neuromodulation approach that is FDA-approved for depression, epilepsy, and headache syndromes and has been reported to be helpful for other diseases characterized by inflammation and neural dysregulation. Transcutaneous VNS stimulates the external branch of the vagus nerve, is minimally invasive, and is well-tolerated in other conditions with few side effects. If well-controlled double-blinded studies demonstrate that transcutaneous auricular VNS helps patients with chronic syndromes such as persistent symptoms after Lyme disease, taVNS will be a welcome addition to the treatment options for these patients.",

A retrospective chart review of these 25 patients undergoing DDDCT therapy and HDDCT demonstrated that 100% improved their tick-borne symptoms, and patients completing 6-7 day pulses of HDDCT had superior levels of improvement versus 4-day pulses if Bartonella was present. At the completion of treatment, 7/23 (30.5%) who completed 8 weeks of DDDCT followed by a 5-7 day pulse of HDDCT remained in remission for 3-9 months, and 3/23 patients (13%) who recently finished treatment were 1 \u00bd months in full remission.

PTLDS (post treatment Lyme disease syndrome) is a controversial topic. It has been described as a source of overdiagnosis and off-label treatment. This review aims to describe the diagnostic errors and adverse events associated with the diagnosis and treatment of PTLDS. systematic review of the literature in the Medline and Cochrane Library databases, according to PRISMA criteria, including randomized clinical trials (RCT), observational studies, and case reports addressing diagnostic errors and adverse events published between January 2010 and November 2020 in English or French. Selection used a quadruple reading process on the basis of the titles and abstracts of the different articles, followed by a full reading. 17 studies were included: 1 RCT, 6 observational studies and 10 case reports. In the 6 observational studies, overdiagnosis rates were very high, ranging from 80 to 100%. The new diagnoses were often psychiatric, rheumatological and neurological. Disorders with somatic symptoms were often cited. Diagnostic delays were identified for cancers and frontoparietal dementia. In the RCT and observational studies, prolonged anti-infective treatments were also responsible for adverse events, with emergency room visits and/or hospitalization. The most common adverse events were diarrhea, sometimes with Clostridium difficile colitis, electrolyte abnormalities, sepsis, bacterial and fungal infections, and anaphylactic reactions. This review highlights the risks of prolonged anti-infective treatments that have not been proven to be beneficial in PTLDS. It emphasizes the ethical imperative of the \"primum non nocere\" principle, which underscores the importance of not causing harm to patients. Physicians should exercise caution in diagnosing PTLDS and consider the potential risks associated with off-label treatments.",

Design: This was a prospective longitudinal single-center pilot study conducted from January 2019 to December 2020. Setting/Location: University of Maryland Lyme Program, Baltimore Maryland. Subjects: Persons presenting for Lyme evaluation for symptoms attributed to Lyme disease. Interventions: Participants attended two 1-h individual instructional sessions consisting of Ayurveda-based dietary intervention and breath-coordinated mind-body practice to be used for home practice. Outcome measures: Standard measures of impact were obtained at baseline, 1, 3, 6, and 12 months using the following validated survey instruments: Perceived Stress Scale (PSS), PROMIS Global Health v1.2 (GH), and PROMIS 29 v2.0 survey. Results: From 216 patients presenting for Lyme evaluation, 19 participants enrolled with 84% completing the study (N\u2009=\u200916). Baseline PROMIS GH scores consisting of general Physical Health (GPH) and general Mental Health (GMH) scores were lower in the study population than in the general U.S. population. PROMIS 29 scores were higher for fatigue, anxiety, and pain than those in the general U.S. population. Over 12-month period, improvement in both the GPH and GMH was 6.09 (confidence interval [95% CI]\u2009=\u20092.71-9.46; p\u2009<\u20090.001) and 4.65 (95% CI\u2009=\u20091.50-7.80; p\u2009=\u20090.004), respectively. PROMIS 29 scores showed the greatest improvement in fatigue at -7.91 (95% CI\u2009=\u2009-12.34 to -3.48; p\u2009<\u20090.001), pain interference -5.08 (95% CI\u2009=\u2009-9.20 to -0.96; p\u2009=\u20090.016), and ability to participate in social roles and activities 7.48 (95% CI\u2009=\u20093.21-11.75; p\u2009=\u20090.001) and least with depression -1.82 (95% CI\u2009=\u2009-4.74 to 1.10; p\u2009=\u20090.223). Employment status had significant effects on almost all outcome scores. Postinfectious state was associated with improvement in anxiety and PSS scores. Conclusions: A multimodal Ayurvedic and breath-coordinated mind-body therapeutic intervention is feasible and a potential nonpharmacologic therapeutic option for persons presenting with pain, stress, fatigue, physical dysfunction, and sleep disturbance attributed to a postinfectious syndrome. Further research is needed to determine efficacy in this population and in other groups with similar symptom complexes due to postinfectious syndromes.",

The disease is caused by Borrelia burgdorferi (Bb) sensu lato which transmits through the bite of Ixodid ticks. Most cases treated soon after infection are resolved by a short course of oral antibiotics. However, 10-20% of patients experience chronic symptoms because of delayed or incomplete treatment, a condition called Post-Treatment Lyme Disease (PTLD). Some Bb persists in PTLD patients after the initial course of antibiotics and an effective treatment to eradicate the persistent Bb is needed. Other organisms that cause persistent infections, such as M. tuberculosis, are cleared using a combination of therapies rather than monotherapy. A group of Food and Drug Administration (FDA)-approved drugs previously shown to be efficacious against Bb in vitro were used in monotherapy or in combination in mice infected with Bb. Different methods of detection were used to assess the efficacy of the treatments in the infected mice including culture, xenodiagnosis, and molecular techniques. None of the monotherapies eradicated persistent Bb. However, 4 dual combinations (doxycycline + ceftriaxone, dapsone + rifampicin, dapsone + clofazimine, doxycycline + cefotaxime) and 3 triple combinations (doxycycline + ceftriaxone+ carbomycin, doxycycline + cefotaxime+ loratadine, dapsone+ rifampicin+ clofazimine) eradicated persistent Bb infections. These results suggest that combination therapy should be investigated in preclinical studies for treating human Lyme disease.",

It is unknown whether subjective dysautonomia obtained from autonomic questionnaires correlates with objective dysautonomia measured by quantitative autonomic testing. The objective of our study was to determine correlations between subjective and objective measures of dysautonomia. This was a retrospective cross-sectional study conducted at Brigham and Women's Faulkner Hospital Autonomic Laboratory between 2017 and 2023 evaluating the patients who completed autonomic testing. Analyses included validated autonomic questionnaires [Survey of Autonomic Symptoms (SAS), Composite Autonomic Symptom Score 31 (Compass-31)] and standardized autonomic tests (Valsalva maneuver, deep breathing, sudomotor, and tilt test). The autonomic testing results were graded by a Quantitative scale for grading of cardiovascular reflexes, sudomotor tests and skin biopsies (QASAT), and Composite Autonomic Severity Score (CASS). Autonomic testing, QASAT, CASS, and SAS were obtained in 2627 patients, and Compass-31 in 564 patients. The correlation was strong between subjective instruments (SAS vs. Compass-31, r\u2009=\u20090.74, p\u2009<\u20090.001) and between objective instruments (QASAT vs. CASS, r\u2009=\u20090.81, p\u2009<\u20090.001). There were no correlations between SAS and QASAT nor between Compass-31 and CASS. There continued to be no correlations between subjective and objective instruments for selected diagnoses (post-acute sequelae of COVID-19, n\u2009=\u200961; postural tachycardia syndrome, 211; peripheral autonomic neuropathy, 463; myalgic encephalomyelitis/chronic fatigue syndrome, 95; preload failure, 120; post-treatment Lyme disease syndrome, 163; hypermobile Ehlers-Danlos syndrome, 213; neurogenic orthostatic hypotension, 86; diabetes type II, 71, mast cell activation syndrome, 172; hereditary alpha tryptasemia, 45). The lack of correlation between subjective and objective instruments highlights the limitations of the commonly used questionnaires with some patients overestimating and some underestimating true autonomic deficit. The diagnosis-independent subjective-objective mismatch further signifies the unmet need for reliable screening surveys. Patients who overestimate the symptom burden may represent a population with idiosyncratic autonomic-like symptomatology, which needs further study. At this time, the use of autonomic questionnaires as a replacement of autonomic testing cannot be recommended.",

Dysautonomia is now widely accepted as a complication of COVID-19 and is an important component of Post-Acute Sequelae of COVID-19 (PASC or long COVID). PASC shares many overlapping clinical features with other infection-associated chronic illnesses including Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Post-Treatment Lyme Disease Syndrome (PTLDS), suggesting that they may share common underlying mechanisms including autonomic dysfunction. Despite the recognition of this complication of Lyme disease in the care of patients with PTLD, there has been a scarcity of research in this field and dysautonomia has not yet been established as a complication of Lyme disease in the medical literature. In this review, we discuss the evidence implicating Borrelia burgdorferi as a cause of dysautonomia and the related symptoms, propose potential pathogenic mechanisms given our knowledge of Lyme disease and mechanisms of PASC and ME/CFS, and discuss the diagnostic evaluation and treatments of dysautonomia. We also outline gaps in the literature and priorities for future research.",

No restrictions on case definitions, study types or specific interventions were applied to enable a comprehensive overview of the available literature. Risk of bias was assessed using the Cochrane risk of bias tools for randomized controlled trials. Certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach.

Heterogeneity was observed regarding inclusion criteria, intervention, length of treatment and outcome measures. For efficacy outcomes, results are presented narratively due to heterogeneity. Eligible studies show no statistically significant difference between antibiotics and placebo regarding quality of life, cognition and depression. Results for fatigue were inconsistent whilst studies with low risk of bias showed no statistically significant difference between antibiotics and placebo. Meta-analysis of safety outcomes showed statistically significantly more adverse events for antibiotics compared to placebo.

The symptoms of LD can persist in individuals chronically, even after the treatment and resolution of the initial infection. These symptoms include various neuropsychiatric manifestations and cognitive decline. The purpose of this review was to report the neuropsychiatric manifestations, cognitive decline, and effects of a delayed diagnosis on symptom severity in patients with long-standing LD (LSLD). A scoping review was conducted utilizing the electronic databases Embase, Ovid Medical Literature Analysis and Retrieval System Online (MEDLINE), and Web of Science. A total of 744 articles were retrieved and considered for inclusion. After a rigorous screening process, 10 articles that met the inclusion criteria for this review were included (i.e., reported neuropsychiatric manifestations and cognitive decline in patients with LSLD and the effects of a delayed diagnosis). Neuropsychiatric manifestations in the patients consisted of suicidal ideation, homicidal tendencies, extreme anger, depressive symptoms, aggression, and anxiety. Cognitive symptoms included dysfunctions in working memory, verbal learning/memory, non-verbal learning/memory, alertness, visuoconstructive, and frontal executive functioning. A delayed LD diagnosis increased symptom severity in most patients. The findings of this review indicate that neuropsychiatric and cognitive symptoms tend to present for a chronic period, even after disease recovery. Although researchers have established a link between a delayed LD diagnosis and increased symptom severity, LSLD is often an overlooked diagnosis in patients with neuropsychiatric symptoms and cognitive decline. More research is needed to compare the time to diagnosis and symptom severity in patients with LSLD.",

We discuss these patients' cases to illustrate three important variables required for long-term remission. First, diagnosing and treating active co-infections, including Babesia and Bartonella were important. Babesia required rotations of multiple anti-malarial drug combinations and herbal therapies, and Bartonella required one or several 6-day HDDCT pulses to achieve clinical remission. Second, all prior oral, intramuscular (IM), and/or intravenous (IV) antibiotics used for chronic Lyme disease (CLD)/post-treatment Lyme disease syndrome (PTLDS), irrespective of the length of administration, were inferior in efficacy to short-term pulsed biofilm/persister drug combination therapy i.e., dapsone, rifampin, methylene blue, and pyrazinamide, which improved resistant fatigue, pain, headaches, insomnia, and neuropsychiatric symptoms. Lastly, addressing multiple factors on the 16-point multiple systemic infectious disease syndrome (MSIDS) model was important in achieving remission. In conclusion, DDDCT with one or several 6-7-day pulses of HDDCT, while addressing abnormalities on the 16-point MSIDS map, could represent a novel effective clinical and anti-infective strategy in CLD/PTLDS and associated co-infections including Bartonella.",

Affected patients suffer from widespread myalgia and severe fatigue consistent with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a poorly understood disorder suspected to result from chronic immune stimulation by infectious and inorganic particles. (2) Methods: In this study we determined the immuno-metabolic properties of MMF phagocytic cells compared to controls, at rest and upon exposure to aluminum oxyhydroxide adjuvant, with or without adsorbed antigens, using protein quantification and an oxygen consumption assay. (3) Results: MMF and control cells similarly internalized the adjuvant and vaccine but MMF cells specifically expressed Rubicon and Nox2, two molecules unique to the LC3-associated phagocytosis (LAP) machinery, a non-canonical autophagic pathway able to downregulate canonical autophagy. MMF cells exhibited an altered inflammatory secretome, producing more pain-inducing CXC chemokines and less TNF-\u03b1 than controls, consistent with chronic myalgia and exhaustion of the immune system previously documented in ME/CFS. MMF cells exhibited mitochondrial metabolism dysfunction, with exacerbated reaction to adjuvanted vaccine, contrasting with limited spare respiratory capacity and marked proton leak weakening energy production. (4) Conclusions: MMF phagocytes seemingly use LAP to handle aluminum oxyhydroxide vaccine particles, secrete pain-inducing molecules, and exhibit exacerbated metabolic reaction to the vaccine with limited capacity to respond to ongoing energetic requests.",
        "39161484": "ID: 39161484\nTitle: What Makes It Tick: Exploring the Mechanisms of Post-treatment Lyme Disease Syndrome.\nAbstract: Post-treatment Lyme disease syndrome (PTLDS), which may also be referred to incorrectly as \"chronic Lyme disease,\" is defined by the Infectious Diseases Society of America (IDSA) as the presence of fatigue, pain, and/or cognitive complaints with the functional impact that persists for more than six months after completing treatment for Lyme disease (LD). These symptoms occur in 10%-20% of patients previously diagnosed with LD caused by the bacteria Borrelia burgdorferi and appropriately treated with a course of antibiotics. The symptoms of PTLDS can be easily overlooked or misdiagnosed as a psychiatric manifestation in geographic locations that rarely see LD. In contrast, geographic locations with a higher prevalence of LD may be more aware of PTLDS symptoms and have higher clinical suspicion leading to this diagnosis. The pathophysiology behind the persistent symptoms some people experience from a primary infection is still largely unknown. Some mechanisms that have been proposed include permanent tissue damage and inflammation, immune system dysfunction, autoimmune response, co-infection, and even persistent infection refractory to treatment. We propose that ongoing PTLDS symptoms seem to be related to an autoimmune response to the tissue damage and inflammation caused by the viable or nonviable spirochete pathogen. At this point, PTLDS is diagnosed clinically as no quantifiable methods are available from laboratory or tissue diagnostics as of 2024. Similar pathophysiological features of PTLDS are seen in diseases such as COVID-19 or chronic fatigue syndrome (CFS). More effective diagnostic approaches might include further studies looking at a possible connection in the genomes of individuals developing PTLDS, quantifiable biomarkers, common inflammatory markers/pathways, and careful histopathological studies of human tissues.",

Here, we report a machine-learning approach to LC/PASC diagnosis on 347 individuals using cytokine hubs that are also capable of differentiating LC from chronic lyme disease (CLD). We derived decision tree, random forest, and gradient-boosting machine (GBM) classifiers and compared their diagnostic capabilities on a dataset partitioned into training (178 individuals) and evaluation (45 individuals) sets. The GBM model generated 89% sensitivity and 96% specificity for LC with no evidence of overfitting. We tested the GBM on an additional random dataset (106 LC/PASC and 18 Lyme), resulting in high sensitivity (97%) and specificity (90%) for LC. We constructed a Lyme Index confirmatory algorithm to discriminate LC and CLD.",
        "39199993": "ID: 39199993\nTitle: Biomarker-Based Analysis of Pain in Patients with Tick-Borne Infections before and after Antibiotic Treatment.\nAbstract: Tick-borne illnesses (TBIs), especially those caused by Borrelia, are increasingly prevalent worldwide. These diseases progress through stages of initial localization, early spread, and late dissemination. The final stage often leads to post-treatment Lyme disease syndrome (PTLDS) or chronic Lyme disease (CLD), characterized by persistent and non-specific multisystem symptoms affecting multiple systems, lasting over six months after antibiotic therapy. PTLDS significantly reduces functional ability, with 82-96% of patients experiencing pain, including arthritis, arthralgia, and myalgia. Inflammatory markers like CRP and TNF-alpha indicate ongoing inflammation, but the link between chronic pain and other biomarkers is underexplored. This study examined the relationship between pain and biomarkers in TBI patients from an Irish hospital and their response to antibiotic treatment. Pain ratings significantly decreased after antibiotic treatment, with median pain scores dropping from 7 to 5 (U = 27215.50, p < 0.001). This suggests a persistent infection responsive to antibiotics. Age and gender did not influence pain ratings before and after treatment. The study found correlations between pain ratings and biomarkers such as transferrin, CD4%, platelets, and neutrophils. However, variations in these biomarkers did not significantly predict pain changes when considering biomarkers outside the study. These findings imply that included biomarkers do not directly predict pain changes, possibly indicating allostatic load in symptom variability among long-term TBI patients. The study emphasizes the need for appropriate antibiotic treatment for TBIs, highlighting human rights issues related to withholding pain relief.",
        "39338918": "ID: 39338918\nTitle: PCR Detection of Bartonella spp. and Borreliella spp. DNA in Dry Blood Spot Samples from Human Patients.\nAbstract: Lyme disease is the most commonly reported vector-borne disease in the United States. Bartonella constitute an additional zoonotic pathogen whose public health impact and diversity continue to emerge. Rapid, sensitive, and specific detection of these and other vector-borne pathogens remains challenging, especially for patients with persistent infections. This report describes an approach for DNA extraction and PCR testing for the detection of Bartonella spp. and Borreliella spp. from dry blood spot (DBS) specimens from human patients. The present study included extraction of DNA and PCR testing of DBS samples from 105 patients with poorly defined, chronic symptoms labeled as Lyme-Like Syndromic Illness (LLSI). Bartonella spp. DNA was detected in 20/105 (19%) and Borreliella spp. DNA was detected in 41/105 (39%) patients with LLSI. Neither group of organisms was detected in DBS samples from 42 healthy control subjects. Bartonella spp. 16S-23S rRNA internal transcribed spacer sequences were highly similar to ones previously identified in yellow flies, lone star ticks, a human patient from Florida, mosquitoes in Europe, or B. apihabitans and choladocola strains from honeybees. These human strains may represent new genetic strains or groups of human pathogenic species of Bartonella. The 41 Borreliella spp. flaB gene sequences obtained from human patients suggested the presence of four different species, including B. burgdorferi, B. americana, B. andersonii, and B. bissettiae/carolinensis-like strains. These results suggest that specific aspects of the DBS DNA extraction and PCR approach enabled the detection of Bartonella spp. and Borreliella spp. DNA from very small amounts of human whole blood from some patients, including specimens stored on filter paper for 17 years.",
        "39345262": "ID: 39345262\nTitle: Current and emerging approaches for eliminating Borrelia burgdorferi and alleviating persistent Lyme disease symptoms.\nAbstract: Lyme disease is the most prevalent tick-borne infection caused by Borrelia burgdorferi bacteria in North America. Other Borrelia species are predominately the cause of this disease in Eurasia with some distinct and various overlapping manifestations. Consequently, caution must be exercised when comparing the disease and its manifestations and treatment regimens in North America and Europe. Diagnosis of the early Lyme disease remains difficult using the currently FDA approved serological tests in the absence of a reported tick bite or of erythema migrans in many individuals, non-specific initial symptoms, and the absence of detectable anti-Borrelia antibodies in the prepatent period of infection. Furthermore, it is difficult to distinguish persistence of infection and disease versus reinfection in the endemic regions of Lyme disease by serological assays. If early infection remains untreated, spirochetes can disseminate and could affect various organs in the body with a variety of disease manifestations including arthralgias and musculoskeletal pain, neurologic symptoms and anomalies, and acrodermatitis chronicum atrophicans (ACA) in Europe. Although most patients recover after antibiotic treatment, an estimated \u223c10-20% patients in the United States show persistence of symptoms known as post-treatment Lyme disease syndrome (PTLDS). The causes and biomarkers of PTLDS are not well-defined; however, several contributing factors with inconsistent degree of supporting evidence have been suggested. These include antigenic debris, dysregulation of immunological response, bacterial persisters, or combination of these features. This review highlights currently employed treatment approaches describing different antimicrobials used, and vaccine candidates tried to prevent B. burgdorferi infection.",
        "39529800": "ID: 39529800\nTitle: A sex-based analysis of complete blood count features during acute, untreated Lyme disease.\nAbstract: Although lymphopenia has been described in acute Lyme disease (LD), the complete blood count (CBC) has not been comprehensively examined, nor have sex-based analyses been conducted. We analyzed CBC values and identified sex-based trends among patients with early LD by comparing both to controls without a history of LD and to patients' pre-morbid values. We enrolled participants from the Mid-Atlantic US with diagnostic erythema migrans and controls with no history of LD. CBC results were obtained, and patient information was recorded using standardized instruments. We also calculated a neutrophil-to-lymphocyte ratio (NLR). We used linear regression to test that CBC results would differ (a) between antibiotic-naive patients with early LD and controls and (b) by measures of acute disease severity. We also performed stratified analyses to assess sex-based differences. In total, 236 antibiotic-naive patients with early LD had significantly lower lymphocytes (\u03b2\u2009=\u2009-0.34, p\u2009<\u20090.001) and significantly higher monocytes (\u03b2\u2009=\u20090.09, p\u2009=\u20090.002) and NLRs (\u03b2\u2009=\u20090.99, p\u2009<\u20090.001) than 61 controls in adjusted analyses. Lymphocytes, monocytes, and NLRs also changed significantly from pre-morbid to acute LD (p\u2009<\u20090.001 for all). Only the NLR was consistently significantly associated with disease severity. A higher proportion of male patients with early LD had acute lymphopenia than female patients with early LD (31.93% vs. 19.66%, p\u2009=\u20090.03); this difference was not present among controls. The presence of lymphopenia and the absence of an elevated total white blood cell count make LD an important diagnostic consideration in patients presenting with undiagnosed infectious syndromes in endemic regions. This may be especially true for male patients.",

In Spain its incidence is much lower than in other European countries, being Asturias the region with the highest incidence. We tried to analyse the clinical and epidemiological aspects in the main hospital in Asturias. Retrospective observational study of patients admitted for Lyme disease in our center over 14years (2009-2022). Clinical, analytical and evolutionary variables were analyzed after one year. Active neuroborreliosis was diagnosed after registering pleocytosis and positive serologies at the cerebrospinal fluid. 108 episodes were analyzed, corresponding to 100 patients coded at discharge as Lyme disease. 58 episodes are discarded due to diagnostic or coding error. 51 episodes were considered active disease, being 38 diagnosed of neuroborreliosis. Tick bite recall and erythema were reported in 55.3% and 31.6% of patients. The most frequent neurological syndromes were radiculoneuritis (36.84%), bilateral facial palsy (13.56%), radiculoneuritis and bilateral facial palsy (10.52%) and multiple cranial mononeuropathy (10.52%), among others. 78.9% achieved a complete recovery, and 15.79% developed post-treatment Lyme disease syndrome. Despite the high incidence of Lyme disease in Asturias, the cases based on hospital admission that can be classified as active disease are lower than those published based on hospital coding. The main source of diagnostic error is positive serological results, without other clinical context, especially in patients studied for cognitive impairment or encephalopathy.",
        "39635815": "ID: 39635815\nTitle: [Long COVID - neurological or somatoform disease?].\nAbstract: Post-COVID condition (also known as long COVID) is a syndrome characterized by persistent symptoms following a suspected or confirmed SARS-CoV-2 infection, lasting for at least two months and are not attributable to other conditions. The most common symptoms include fatigue, diffuse pain, post-exertional malaise and \u201cbrain fog\u201d (impairment of memory and concentration). The pathomechanism of long COVID is the subject of ongoing, intensive research. Our purpose was to review the literature on the pathomechanism of long COVID. We reviewed original and review articles in Hungarian and English on the pathomechanism of long COVID, published between January 2019 and June 2024, in the PubMed and Google Scholar databases. Potential underlying causes of the symptoms are outlined in three main theories. 1) The concept of \u201clong COVID as a distinct neurological disease\u201d suggests that direct viral neuroinvasion, apoptosis, and demyelination processes are responsible for the symptoms. 2) The theory of \u201clong COVID as a systemic disease with neurological symptoms\u201d is based on the virus induced, prolonged cytokine and chemokine release, as well as the reactivation of latent viral infections. 3) According to the concept of \u201clong COVID as a somatoform disorder\u201d, the disease results from abnormal activation of the proinflammatory cytokine network leading to central nervous system sensitization, a well-known psychoneuroimmunological mechanism. Our study highlighted significant overlaps between long COVID and conditions such as chronic fatigue syndrome/myalgic encephalomyelitis, a group of symptoms not defined as a distinct mental disorder in DSM-5, but commonly referred to as Gulf War syndrome, chronic Lyme disease and somatic symptom disorder. The pathomechanism of long COVID, which presents with a wide range of nonspecific symptoms, remains unknown, and no reproducible disease-specific biomarker has been identified to date. Clarifying the etiology of the disease is crucial for determining adequate and effective therapeutic methods.

Recent environmental and socioecological changes have led to an increased incidence of Lyme and other tick-borne diseases, which enhances the urgency of identifying and mitigating adverse outcomes of Lyme disease exposure. Lyme disease during pregnancy, especially when untreated, may lead to adverse pregnancy and neonatal outcomes; however, long-term child outcomes following utero exposure to Lyme disease have not yet been systematically assessed. This concise review describes the current state of knowledge of Lyme disease as a congenital infection and the potential effects of in utero exposure to Lyme disease infection on the neurodevelopment of infants and children. We highlight the importance of distinguishing between acute Lyme disease and a chronic condition termed Post-Treatment Lyme Disease Syndrome, as the impacts of both conditions on the developing fetus and subsequent child development may differ. The importance of placental pathology for patients with acute or chronic symptoms of Lyme disease in pregnancy is explored. Future research aiming to understand and protect neurodevelopment after antenatal Lyme disease must carefully collect potentially confounding variables such as symptomatology and treatment, use clear and standard case definitions, and follow children into school-age and beyond.",

The biological basis for PTLDS is poorly understood and no evidence-based treatment has been identified. Genetic studies have the potential to elucidate PTLDS pathophysiology and identify treatment targets. We used electronic health record data (EHR) and genetic data from a linked biorepository to conduct a genome-wide association study (GWAS) for PTLDS among patients from a Pennsylvania health system. We evaluated the validity of the GWAS results in two separate conditions that have hypothesized overlapping pathophysiology, fibromyalgia and myalgic encephalomyelitis - chronic fatigue syndrome (ME/CFS). GWAS analyses were performed using logistic regression in SUGEN, assuming an additive genetic model, and adjusting for age, sex, array, and the first 10 principal components calculated from whole genome genotyping to adjust for ancestry, and accounting for relatedness including all 1st degree relationships. The functional mapping and annotation analysis (FUMA) tool was used to explore top findings from our GWAS. Among the 161,875 eligible MyCode participants with genotyping, there were 3,585 who met the criteria for treated Lyme disease. A subset of 695 (19.4%) of these patients met the criteria for PTLDS and the remaining 2890 were classified as controls. We identified two PTLDS loci that reached the suggestive significance threshold (P\u2009<\u20095\u2009\u00d7\u200910-\u20097), with lead variants rs77857587, near IRX1, and rs10833979, near GAS2. Our top index single nucleotide polymorphism (SNP), rs77857587, is in high linkage disequilibrium with a long-range protein quantitative locus SNP, rs111774530, for the MARC2 (Mitochondrial Amidoxime Reducing Component 2) protein. We identified 5,041 cases of fibromyalgia (150,599 controls) and 2,268 cases of ME/CFS (151,594 controls) among the MyCode participants. Neither of the two suggestively significant loci were associated with fibromyalgia or ME/CFS. We identified two PTLDS loci that reached a suggestive significance threshold. Our top index SNP is associated with the MARC2 protein, a protein that has been linked to multiple immune checkpoints. Further study is needed in a larger population to evaluate whether there is genetic evidence of the role of immune response in the occurrence of PTLDS.",

Case series suggest disulfiram may help to reduce the symptoms of patients with persistent symptoms despite prior antibiotic treatment for Lyme disease. This pilot study assessed safety, tolerability, and signs of clinical response. Participants with a history of previously treated Lyme disease and persistent fatigue were randomly assigned in a double-blinded fashion to either Group A (disulfiram for 4 weeks and placebo for 4 weeks) or Group B (disulfiram for 8 weeks). Primary outcome endpoint was at 10 weeks with a follow-up at 14 weeks. The primary aim was to assess safety and tolerability. A clinical aim assessed signs of clinical improvement using well-validated measures, focusing on improvement in fatigue and quality of life. Target enrollment was 24 participants. 940 individuals were screened, 11 were enrolled and nine participated in the trial. Dosing started low and increased based on response and tolerance to a maximum of 500 mg daily. Safety. Two participants discontinued medication due to clinical worsening, one of whom was briefly hospitalized. Three additional participants were withdrawn from treatment due to lab test abnormalities. Tolerability. Only three of nine participants completed the full course of treatment (two in Group A and one in Group B). Lower doses were better tolerated than the highest dose. Clinical response. Of nine participants, clinically meaningful improvement was noted in fatigue for six and in quality of life for four. Among the six fatigue responders, improvement was also noted on a multiple domain symptom index (six of six), overall symptom burden (five of six), and functional impairment (four of six). The study was terminated early due to end of project funding, higher than expected adverse events, and recognition that sufficient information was gathered to inform future studies. This study reveals the risks associated with disulfiram, especially at higher doses, while suggesting potential clinical benefits among some participants.

        "40330647": "ID: 40330647\nTitle: Case Report: The intersection of psychiatry and medicine: diagnostic and ethical insights from case studies.\nAbstract: The intersection of psychiatry and medicine presents unique diagnostic and ethical challenges, particularly for conditions involving significant brain-body interactions, such as psychosomatic, somatopsychic, and complex systemic disorders. This article explores the historical and contemporary issues in diagnosing such conditions, emphasizing the fragmentation of medical and psychiatric knowledge, biases in clinical guidelines, and the mismanagement of complex illnesses. Diagnostic errors often arise from insufficient integration between general medicine and psychiatry, compounded by the reliance on population-based guidelines that neglect individual patient needs. Misclassification of conditions like myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, and fibromyalgia as psychosomatic or psychogenic has led to stigmatization and delayed care. While these conditions are referenced as emblematic examples of misclassified and poorly understood disorders, the five clinical cases discussed in this article do not directly illustrate these diseases. Instead, they exemplify shared diagnostic and ethical dilemmas at the medicine-psychiatry interface, including uncertainty, fragmentation, and the risk of epistemic injustice. The article critically examines terms like medically unexplained symptoms and functional disorders, highlighting their limitations and potential for misuse. Case examples underscore the consequences of diagnostic inaccuracies and the urgent need for improved approaches. Ethical considerations are also explored, emphasizing respecting patient experiences, promoting individualized care, and acknowledging the inherent uncertainties in medical diagnosis. Advances in technologies such as brain imaging and molecular diagnostics offer hope for bridging the gap between psychiatry and medicine, enabling more accurate assessments and better patient outcomes. The article concludes by advocating comprehensive training at the medicine-psychiatry interface and a patient-centered approach that integrates clinical observation, research insights, and a nuanced understanding of mind-body dynamics.",

There is currently no specific treatment for this condition. The subjects were divided into two groups: one group received 150 mg/day of Pycnogenol\u00ae alongside standard management, while the control group received only standard management. The observation period lasted for six months. Forty subjects with history of Lyme Disease and persistent symptoms completed the study: 20 in the Pycnogenol\u00ae group, 20 in the control group. No side effects from the supplementation were observed. The tolerability was optimal as no supplemented subject had to stop management and compliance was optimal with 97% of the Pycnogenol\u00ae capsules correctly used. The two groups were comparable for sex, age distribution and for their main clinical findings and signs/symptoms at inclusion. During the study, corticosteroids at low dose were used on demand in 10% of subjects using Pycnogenol\u00ae and significantly more, in 45% of the control patients (P<0.05). After 6 months, the number of patients experiencing symptoms was significantly lower in the Pycnogenol\u00ae group compared to the control group across all symptoms (P<0.05). After 6 months, the intensity of all symptoms in the Pycnogenol\u00ae group, was significantly lower, according to the scores in comparison with the control group (P<0.05). Plasma oxidative stress was significantly reduced in subjects of the Pycnogenol\u00ae group (P<0.05) in comparison with controls. The improvement in plasma oxidative stress was seen in all subjects using Pycnogenol\u00ae. Knee effusion on ultrasound was seen in 12 subjects of the supplement group at inclusion and in 3 Pycnogenol\u00ae subjects at the end of the study in comparison with 12/20 subjects in the control group at inclusion and 8/20 at the end of the study. (P<0.05). Finally, ESR (Erythrocyte sedimentation rate, a global marker of inflammation) was significantly more reduced in the Pycnogenol\u00ae group by the end of the study compared to controls (P<0.05). In conclusion, the present registry study showed that Pycnogenol\u00ae intake for 6 months in patients with persistent symptoms of Lyme disease can help relieve the main symptoms by reducing inflammation and oxidative stress. Pycnogenol's anti-inflammatory and antioxidant double activity may help safely and effectively controlling the chronic inflammatory process.",

Rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) are often used to assess joint pain in this setting; however, their clinical utility remains unknown. Our objective was to define the frequency of these autoantibodies in a large cohort of carefully characterized patients with PTLD meeting a research case definition and to determine the clinical implications of these tests.\u00a0RF and ACPA were tested as indicated clinically and abstracted by chart review. The prevalence of antibodies and their relationship to symptoms were examined. Of the 167 patients included in the analysis, RF status was documented at least once for 78.4% (131 of 167), and ACPA status was available at least once for 88.0% (147 of 167). RF was positive in 3.8% (five of 131), and ACPA was positive in 4.8% (seven of 147)\u00a0at least at one time point.\u00a0A total of 7.2% (12 of 167)\u00a0patients were found to have a positive RF or ACPA test at least at one time point.\u00a0There was no difference in the proportion of patients with RF and/or ACPA based on the initial presenting manifestations of their LD, nor the symptoms of PTLD at later evaluation; however, the small sample size may limit our ability to detect these clinical differences. We found a low prevalence of RF and ACPA in this study, similar to the known rates in the general population. This reflects the lack of inflammatory arthritis in this population with clinically defined PTLD and arthralgia only.",

The COVID-19 pandemic has brought this issue to the forefront and Long COVID is recognized to be an infection associated chronic condition. However, given the wide range of Long COVID presentations, the singular expression gives a false sense of simplicity.

Consequently, (C)LD/PTLDS patients exhaust their (health)care options in their search for symptom relief, falling into cycles of starting and stopping (health)care-seeking. This meta-synthesis reviewed 13 qualitative interview studies representing the (health)care-seeking experiences of 216 (C)LD/PTLDS patients across five countries (i.e., United States, Canada, Netherlands, Australia, France) to examine how communication catalyzes patients' (health)care-seeking behaviors. This study proposes a model of (health)care (dis)engagement, identifying communication as a motor moving patients through (health)care-seeking both within and outside of biomedical models of care. This model extends our understanding of communicative (dis)enfranchisement processes and understandings of why patients disengage and reengage in healthcare-seeking behaviors. Theoretical and practical implications and future directions are discussed.",
        "40662763": "ID: 40662763\nTitle: Class and isotype of VlsE-specific antibody differentiates Lyme disease stage.\nAbstract: Establishment of immunoglobulin diversity is contingent on recombination that occurs both at the Fab and at the Fc regions of the immunoglobulin, and this process is time dependent. Based on this principle, we questioned whether Lyme disease stage can be distinguished by quantification of immunoglobulin class and IgG isotype specific to VlsE in serum from clinically characterized patients. We used an enzyme immunoassay to categorize serologic antibodies to VlsE antigen as well as machine-learning techniques to train and integrate multiple predictors to identify likely disease stage. We found that IgM/IgG3/IgG1/IgA1 was enriched in serum obtained in the earliest stages, whereas IgG3/IgG1/IgG4 was enriched in Lyme arthritis. IgG2 detection was unremarkable across all disease stages. Post-Treatment Lyme Disease Syndrome (PTLDS) serum was enriched in IgG3/IgG1/IgA1 but lacked IgM. The multivariable models showed better predictive accuracy than any single immunoglobulin model, with more than half of panels perfectly identified by random forest under cross validation (56%) vs a maximum of 38% for a model using IgG1 alone. The findings suggest a characteristic succession of VlsE-specific antibody switching between immunoglobulin class and IgG isotype as Lyme disease progresses from early to late stages. The data also suggest that immunoglobulin class and IgG isotyping are likely more helpful to distinguish early Lyme disease cases. Comprehensive evaluation of immunoglobulin class (M, G, A) and IgG isotypes (1/2/3/4) provides time-dependent pathogen-induced host response information to current Lyme disease antibody detection and may be useful for differentiation of disease stage. The order of switching between the immunoglobulin heavy chain (Fc) is time dependent, progressing from IgM/D to IgG3/IgG1/IgA1/IgG2/IgG4 and later to IgE/IgA2. In this study, we show that B. burgdorferi-VlsE-specific antibody switching proceeds in a predictable sequence between class (Ig M/G/A) and IgG isotype (IgG 1/2/3/4) as Lyme disease progresses from early to late stage and that antibody class and isotype may be more helpful to distinguish the early stages of Lyme disease. This study advances our understanding of the tempo and structure of the humoral immune response to B. burgdorferi and is applicable to the development of new diagnostic assays for Lyme disease.",

Persistent LB forms may involve biofilms, potentially contributing to antibiotic tolerance. Whole genome sequencing (WGS) was conducted on 7 B. afzelii and 5 B. garinii isolates from erythema migrans skin biopsies. Biofilms were analyzed for extracellular DNA (eDNA) content and biomass. A phenol red metabolic assay assessed the minimum inhibitory concentration (MIC) and minimum biofilm inhibitory concentration (MBIC) of amoxicillin, azithromycin, ceftriaxone, and doxycycline. Phylogenetic analysis revealed B. afzelii and B. garinii formed distinct clades, while B. burgdorferi B31 clustered separately. Core genome analysis showed 38.9% of genes were shared between B. afzelii and B. garinii, decreasing to 26.1% with B. burgdorferi. The cloud genome expanded from 34.4% to 53.4% with the addition of B. burgdorferi. No antimicrobial resistance genes were detected. Surface adhesion gene profiles exhibited significant variation across species, suggesting potential functional differences in host adaptation. B. afzelii and B. garinii species exhibited biofilms, with biomass correlating significantly with eDNA production. MIC values were 0.25 \u03bcg/mL (amoxicillin, ceftriaxone), 0.125 \u03bcg/mL (azithromycin), and 0.5 \u03bcg/mL (doxycycline), with no significant interspecies differences. However, MBIC values were considerably higher: 2 \u03bcg/mL (amoxicillin, azithromycin), 16 \u03bcg/mL (ceftriaxone), and 32 \u03bcg/mL (doxycycline). Biofilms in B. afzelii and B. garinii significantly reduce antibiotic efficacy, particularly ceftriaxone and doxycycline. These in vitro findings highlight the need for targeted therapeutic strategies and suggest biofilms may impact treatment outcomes in LB.",

Characterized by fatigue, generalized myalgias, and cognitive impairment, PTLD symptomatology closely resembles long COVID and other post-acute infection syndromes. While prior studies suggest immune dysregulation as a factor in PTLD pathogenesis, the mechanisms underlying its heterogeneous presentation and severity remain unclear. To associate symptom burden with discrete immune phenotypes, we applied factor analysis to self-reported symptom data from 272 PTLD patients to generate patient subgroups. We then immunophenotyped peripheral blood cells of these individuals and 28 healthy controls through 19-parameter flow cytometry and cytokine profiling to associate PTLD status and the newly defined subgroups with specific immune states. Our PTLD cohort had fewer circulating CXCR5+ CD4+ na\u00efve T cells relative to healthy controls (5.2% vs. 8.3%, Padj < 0.001). These cells were positively associated with musculoskeletal pain in PTLD participants, but not healthy controls. This and additional immunophenotypic alterations, including an increased prevalence of CXCR3+ CCR4- CCR6- CD8 T cells (43.1% vs. 25.7%, Padj < 0.01), permitted the creation of an elastic net classifier which identified PTLD with moderate efficacy (AUC 0.83). Measurement of cytokines did not reveal associations with PTLD and did not improve the performance of the model. While we could not identify immune features which distinguished all patient subgroups, we did observe a female-specific increase in central memory CD8 T cells restricted to one high-fatigue patient subgroup. Additionally, factor analysis revealed multiple associations between immune cell frequency and the severity of specific symptoms. Collectively, our findings add to growing evidence of immune dysfunction as a prominent feature of PTLD.",

Disulfiram (DIS), a drug for alcoholism, is under investigation as a potential adjunctive treatment, but its low bioavailability, rapid metabolism, and safety concerns urge the development of improved formulations for clinical translation. Methods: Screening dissolution and permeation studies were investigated for vehicle and excipient selection, following the pharmacopeia perspectives to develop and optimize the low-dose DIS rectal suppository intended for application in post-treatment Lyme disease syndrome (PTLDS). Further characterizations were carried out by differential scanning calorimetry, X-ray diffraction, and infrared spectroscopy. Results: Cyclodextrin (CD) encapsulation was investigated to improve the aqueous solubility of the hydrophobic drug. The dissolution of DIS from fatty base suppository was very slow; it was remarkably improved by the molecular encapsulation of the drug with CDs. The dissolution of DIS from a water-soluble base was more favorable, but incomplete. In the polyethylene glycol (PEG) based suppositories, the addition of CDs already in a physical mixture ensured the dissolution of the drug. The presented drug delivery system relates to a novel preparation for rectal administration comprising a low-dose disulfiram with improved solubility and permeability by the PEG and hydroxypropyl-\u03b2-cyclodextrin (HPBCD) synergistic matrix. Conclusions: The rectal dosage form containing the drug and CD in the physical mixture is advantageous, avoiding the hepatic first-pass effect, minimizing dose-limiting toxicity, simplifying production, and fasting the availability of the repositioned drug.",

Despite promising results from individual randomized controlled trials (RCTs), to our knowledge, no systematic review has exclusively synthesized RCT evidence on KY across health domains. To critically assess the clinical effectiveness and safety of KY interventions across diverse cognitive, psychological, emotional, sleep-related, and physical health outcomes. PRISMA-guided systematic review of RCTs evaluating KY was conducted from January 2015 to December 2024. Databases included MEDLINE (PubMed), Scopus, CENTRAL (Cochrane Library), Embase, PsycINFO, and CINAHL. Risk of bias was independently assessed using the Joanna Briggs Institute Critical Appraisal Checklist. Studies were conducted worldwide, across multiple sites. Approximately 1370 participants ranging from healthy adults to those diagnosed with conditions such as Mild Cognitive Impairment (MCI), Generalized Anxiety Disorder (GAD), Obsessive-Compulsive Disorder (OCD), Post-Traumatic Stress Disorder (PTSD), insomnia, chronic pain, and post-treatment Lyme disease syndrome. No serious adverse events were reported. KY protocols (pranayama, asana/kriya, meditation, chanting) delivered in person, online, or hybrid formats; duration 6 weeks-12 months (most 8-12 weeks) with practice from once weekly to daily. Pre-specified validated measures assessed cognitive function, psychological symptoms (e.g., anxiety, depression), sleep quality, emotional regulation, and physical health outcomes (e.g., hippocampal metrics, absenteeism, blood pressure). This systematic review included 15 studies, among which 13 demonstrated a low risk of bias. The findings suggest that KY significantly improves memory, executive functioning, and hippocampal structure, reduces symptoms of anxiety, PTSD, OCD, and depression, enhances sleep quality and emotional regulation, and modestly improves fatigue, blood pressure, and functional outcomes. KY appears safe and shows benefits for a wide range of cognitive, psychological, and physical health conditions.

        "41024925": "ID: 41024925\nTitle: Reassessing Chronic Lyme Disease and Post-Treatment Lyme Disease Syndrome as Focal Infections.\nAbstract: The complete clinical spectrum of Lyme borreliosis has been recognized for nearly 50 years, yet its diagnosis remains challenging due to the heterogeneity of symptoms. While many symptoms are likely nonspecific, a recurring cluster, including severe fatigue, brain fog, cognitive decline, memory impairment, joint and muscle pain, limb numbness, headaches, and low-grade fever, is often labeled in the scientific literature as post-treatment Lyme disease syndrome (PTLDS), and in the popular media as \"chronic Lyme disease.\" Based on clinical experience and retrospective case analysis, this study hypothesizes that in many such cases, these persistent symptoms are not sequelae of Lyme borreliosis but manifestations of an undiagnosed focal infection, most commonly chronic tonsillitis or periodontal disease. The hypothesis is supported by the observation that the symptom profile of PTLDS is remarkably similar to that seen in focal infections, and by documented patient outcomes following treatment of these localized infections. This study compiles and analyzes clinical data to support the reinterpretation of PTLDS and \"chronic Lyme disease\" as misattributed focal infections in a subset of patients.",
        "41046949": "ID: 41046949\nTitle: Hypercholesterolemia enhances early dissemination and Borrelia burgdorferi burden in a mouse model.\nAbstract: The Lyme disease spirochete, Borrelia burgdorferi, requires cholesterol to grow. The spirochete acquires cholesterol from the host to form cholesterol glycolipids, which are then incorporated into the spirochete's membrane. This study aimed to determine whether higher levels of serum cholesterol could facilitate the infection and contribute to the pathogenesis of Lyme disease. We investigated the effect of acute and chronic hypercholesterolemia on spirochetal infection in C3H/HeJ mice fed a high-fat diet (HF) compared to mice fed a control diet. The course of infection in mice was followed for 3 weeks (short-term effects) and 16 weeks post-infection (long-term effects) by measuring spirochete bioluminescence in vivo. At the endpoint, bacterial burden was measured in tissues by real-time PCR, and histology was performed to assess differences in the inflammatory response. Between days 10 and 14 post-infection, live imaging showed that mice on a HF diet presented a significantly higher spirochetal burden and greater dissemination than the controls. These differences were transient and restricted to the first two weeks of infection, without long-term effect observed. Histology showed no significant differences in inflammation between HF and control mice. However, qPCR showed that mice fed with HF diet had a higher B. burgdorferi burden in tissues, including heart, visceral, and subcutaneous fat. These findings revealed that high cholesterol levels resulting from a HF diet led to increases in spirochetal burden and dissemination early in the infection, suggesting that cholesterol may contribute to spirochete persistence and associated Lyme disease symptoms.",
        "41065377": "ID: 41065377\nTitle: The multiplexed single-tier InBios Lyme Detect Multiplex ELISA is more sensitive than standard two-tier tests in the early stages of Lyme disease.\nAbstract: There are nearly 500,000 cases of Lyme disease each year in the United States; 10%-20% of them result in the development of a debilitating chronic disease known as post-treatment Lyme disease. Existing standardized and modified two-tier tests (STT/MTT) suffer from poor detection rates in the first weeks of infection, where the antibody response, the basis of diagnosis, is developing but is not robust enough for detection. During this early window, false negative results are common, which leads to delayed treatment and increases the likelihood of developing severe symptoms. The InBios Lyme Detect Multiplex ELISA is a microarray-based assay designed to capture a set of commonly used diagnostic antibodies specific to Borrelia burgdorferi from human serum. The multiplex array captures common diagnostic antibodies, including those to C6, VlsE, and OspC, and has in-line controls. Diagnostic index scores are calculated from the relative abundance of controls and antibodies using a proprietary machine learning algorithm. The assay was evaluated here for reproducibility, accuracy, and performance. It was found to be reproducible using a group of 30 samples run in triplicate. The assay performed well in a blinded panel, correctly identifying all standard two-tier test-positive samples and controls while also detecting 21 of 79 samples that were clinically diagnosed but undetectable by standard Lyme serologic tests. There was one false positive from 66 look-alike disease samples and 146 healthy controls. The InBios assay has the potential to improve diagnostic sensitivity within the early weeks of infection while matching the specificity of current diagnostic tests. During initial Lyme disease infection, existing diagnostic tests have poor sensitivity, resulting in a high number of false-negative tests. This is due to the lag between infection and a robust immune response capable of being detected by such tests. With a multiplexed array of nine unique antibody targets specific for Borrelia burgdorferi, interpreted by a proprietary machine learning algorithm, the InBios Lyme Detect Multiplex ELISA has the potential to increase diagnostic sensitivity within the first few weeks of infection, reducing the number of false-negative tests. Improving diagnostic sensitivity during early infection would reduce the risk of developing severe symptoms, including post-treatment Lyme disease.",

Recent evidence has also identified certain Human Leukocyte Antigen (HLA) alleles that are significantly associated with ME/CFS risk/protection. Here we tested the hypothesis that ME/CFS risk or protection conferred from those HLA alleles is associated with binding affinity to antigens of HHV viruses, a critical step in initiating the adaptive immune system response to foreign antigens. Specifically, we determined in silico the predicted binding affinity of two susceptibility alleles (C*07:04, DQB1*03:03) and two protective alleles (B*08:01, DPB1*02:01) to >\u200910,000 antigens of the 9 Human Herpes Viruses (HHV1, HHV2, HHV3, HHV4, HHV5, HHV6A, HHV6B, HHV7, HHV8) which have been implicated in the etiology of ME/CFS. We found that the binding affinity of all HHV antigens to the susceptibility alleles was significantly weaker than the binding affinity to the protective alleles (P\u2009<\u20090.001). In fact, none of the HHV antigens showed strong binding to the susceptibility alleles, in contrast to the strong bindings showed by the protective alleles. These findings are in keeping with the hypothesis that the effect of a putative HHV insult in contributing to ME/CFS is modulated by the host's HLA immunogenetic makeup. We speculate that strong HLA-antigen binding likely protects against ME/CFS via elimination of virus antigens; conversely, weak HLA-antigen binding may permit persistence of foreign antigens, contributing to ME/CFS and other chronic conditions. Finally, with respect to the latter, we determined the binding affinities to the 4 HLA alleles above to pathogens causing two chronic diseases with very similar symptomatology to ME/CFS, namely Long COVID and post-treatment Lyme disease syndrome (PTLDS). We found that the 2 ME/CFS susceptibility HLA alleles above had very weak binding with SARS-CoV-2 virus glycoprotein (involved in Long COVID) and 5 proteins of Borrelia burgdorferi (involved in PTLDS), in contrast to the ME/CFS protective alleles that showed strong bindings. These findings support the hypothesis that ME/CFS, long COVID and PTLDS are caused by persistent pathogenic antigens that could not be eliminated due to inadequate protection by the patient's HLA makeup.",

These insights are crucially important for advancing people-centred, high-quality healthcare and achieving improved health outcomes. Cutaneous leishmaniasis (CL) causes chronic, disfiguring skin lesions leading to a significant burden on the affected communities and the health systems. Our study aims to examine the experiences of people with CL after entering the biomedical healthcare system. We also integrate these findings with our previous work to map the entire CL patient journey in a disease-endemic district in Sri Lanka. We conducted a qualitative study in three rural communities with high disease prevalence in the Anuradhapura district, Sri Lanka. We collected data through (1) a participant experience reflection journal (PERJ), (2) post-PERJ interviews and (3) an interview study with healthcare professionals. We analysed data through thematic analysis. Thirty PERJs were completed by individuals with CL, with 25 participating in post-PERJ interviews and 16 healthcare professionals participated in the key informant interviews. Upon entering a biomedical healthcare facility, a person with CL navigated through the stages of clinical suspicion and laboratory diagnosis, receiving treatment and achieving a cure (as clinically confirmed by the treating dermatologist). Although many physicians accurately suspected cases upon initial presentation, some failed to clinically diagnose CL promptly. Some patients experienced prolonged waiting times for their initial consultations with the dermatologist and to receive diagnostic test results. Accessibility issues, travel and meal costs, and competing responsibilities like household work, education, and employment further added to the burden of attending frequent clinic visits for CL. Despite the long and painful nature of the treatment, compliance among people with CL remained satisfactory, with rare reports of treatment failure. For some people, the CL patient journey extends beyond the clinically defined cure, as they continue to live with constant fears, perceived physical impacts associated with the disease, and effects of treatment. We found that, despite certain positive aspects, the CL patient journey is complex, with substantial and pervasive delays and barriers along with psychosocial impacts that persist beyond clinical cure. Our study findings can inform evidence-based, context-specific interventions to reduce the public health burden of CL in resource-limited settings.",

Neurological manifestations occur in 3-15% of infections and can present as polyradiculitis, meningitis, and rarely as encephalomyelitis. The disease is treatable with antibiotics. The S3 guideline \"Neuroborreliosis\" has been updated in accordance with the methodological standards of the \"Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e. V.\" (AWMF register number 030/071). Eighteen AWMF member societies, the Robert Koch Institute, the \"Paul-Ehrlich-Gesellschaft f\u00fcr Infektionstherapie\", the \"Schweizerische Neurologische Gesellschaft\", the \"\u00d6sterreichische Gesellschaft f\u00fcr Neurologie\", the \"Deutsche Borreliose-Gesellschaft\" and two patient organizations were involved in the update. The guideline aimed at physicians in practice and hospital settings who are involved in the treatment of neuroborreliosis in children and adults. For the first time, there is Class Ia evidence that a 14-day course of antibiotics is therapeutically sufficient in early neuroborreliosis. Additionally, it is now recommended that the administration of steroids alongside antibiotic therapy is not advised in cases of facial palsy within the context of a neuroborreliosis that is probable or confirmed according to diagnostic criteria. The age limit for doxycycline in the treatment of neuroborreliosis in children under 8 years has been removed. There are still no valid study data on the effectiveness of combination antibiotic treatments. A systematic review on the therapy of so-called Post-Treatment Lyme Disease Syndrome (PTLDS) showed that parameters such as quality of life, fatigue, depression, and cognition do not respond to antibiotic therapy.

Although in some cases Lyme borreliosis progresses to serious outcomes, no human vaccines are available for its prevention. A previous report showed positive immunogenicity and safety of VLA15, an investigational Lyme borreliosis vaccine based on Borrelia burgdorferi outer surface protein A (OspA), when administered as a 0-2-6-month or 0-6-month primary series to children, adolescents, and adults. Here, we report data from the same trial after receipt of an initial booster dose at month 18. This ongoing, randomised, observer-blind, placebo-controlled, phase 2 trial is taking place at 14 clinical study centres in Lyme borreliosis-endemic areas in the USA. Healthy, eligible participants aged 5-65 years were enrolled. Participants were randomly assigned within each age cohort (18-65 years, 12-17 years, and 5-11 years) in a 1:1:1 ratio to receive intramuscular injections of VLA15 at months 0, 2, and 6; VLA15 at months 0 and 6 and placebo at month 2; or placebo at months 0, 2, and 6. In this phase of the trial, a month 18 VLA15 booster vaccination was administered to participants in both VLA15 groups (termed VLA15 M0-2-6-18 and VLA15 M0-6-18, respectively); the placebo group received placebo at month 18. Data up to month 12, including the primary endpoints, have been reported previously; this report includes data up to month 19. Secondary endpoints related to the month 18 booster vaccination included OspA serotype-specific IgG geometric mean titres (GMTs; evaluated in the per-protocol analysis set) and solicited and unsolicited adverse events (evaluated in the safety analysis set [ie, all participants who received one or more vaccinations]) from month 18 to month 19. This trial is registered at ClinicalTrials.gov, NCT04801420, and is closed for recruitment. Between March 15, 2021, and Feb, 24, 2022, 625 participants were randomly assigned and received the first vaccination. 532 (85%) of 625 participants were White, 68 (11%) were Black or African American, 13 (2%) were Asian, one (<1%) was an American Indian or Alaska Native, and 11 (2%) had their race recorded as other. 321 (51%) of 625 participants were female and 304 (49%) were male. The month 18 booster vaccination was administered to 449 participants at 13 of the trial sites (148 participants in the VLA15 M0-2-6-18 group; 143 participants in the VLA15 M0-6-18 group; 12 other VLA15 recipients; and 146 participants in the placebo group) between Sept 21, 2022, and Jan 24, 2023. The 12 other VLA15 booster recipients, of whom 11 received VLA15 and one received placebo for the month 18 booster, received at least one primary or booster VLA15 dose but could not be evaluated within a designated VLA15 group for safety because of missed or incorrect vaccinations, and were excluded from post-booster immunogenicity analyses. Of the 513 participants included in the per-protocol analysis set, 398 received the booster and 394 completed the month 19 visit. OspA-specific IgG GMTs in both VLA15 groups declined after the primary series up to month 18. At 1 month after the month 18 booster vaccination, GMTs in both VLA15 groups rose to levels that exceeded those after the primary series, ranging in the overall population from 1057\u00b70 U/mL (95% CI 843\u00b71-1325\u00b71; serotype 1) to 1807\u00b79 U/mL (1486\u00b72-2199\u00b73; serotype 2) in the M0-2-6-18 group and from 830\u00b70 U/mL (621\u00b73-1108\u00b79; serotype 1) to 1603\u00b71 U/mL (1239\u00b77-2073\u00b70; serotype 2) in the M0-6-18 group. GMTs at month 19 were higher in the paediatric cohorts compared with adults, consistent with observations after the primary vaccination series. The tolerability profile of the month 18 booster was similar to that of the primary doses and generally similar across age cohorts. Related unsolicited adverse events were reported by four (1%) of 302 VLA15 booster vaccination recipients and three (2%) of 147 placebo booster recipients within 1 month after the month 18 booster; all of these events resolved without sequelae. Unsolicited adverse events leading to trial withdrawal, unsolicited serious adverse events, and adverse events of special interest that were reported up to month 19 were all considered unrelated to trial vaccination and occurred before the month 18 booster. No deaths were reported up to month 19 of the trial. The safety and robust anamnestic immune responses associated with VLA15 boosting support its use as a strategy to increase anti-OspA antibody levels before tick season among children, adolescents, and adults. Forthcoming data after administration of subsequent annual boosters will provide further information about VLA15 antibody persistence and boostability. Valneva and Pfizer.",

We estimate regionally adjusted prevalence of persistent symptoms, investigate seroprevalence (IgG) and ongoing infections, and examine associated demographic and clinical factors. Persons aged 18 years or older with persistent symptoms lasting six months or more attributed to tick bites or tick-borne diseases, were recruited into a nationwide cross-sectional study. Demographic data were recorded. Medical records were collected (February 2020 - April 2022) and reviewed for tick bites, tick-borne infections, antibiotic treatment, and clinical findings. Outcome measures included somatic symptoms (PHQ-15), fatigue (Fatigue Severity Scale), physical health (RAND-36), and affective symptoms (HAD Scale). Laboratory assessments included polymerase chain reaction (PCR) analysis of blood samples for Borrelia burgdorferi (Bb) and other known tick-borne pathogens, along with IgG antibody detection. The highest prevalence of persistent symptoms attributed to tick bites or tick-borne diseases was found in southwestern Norway (0.152-0.155%); the lowest was in the north (0.033%), which also had significantly lower Bb-IgG seroprevalence (15.4% compared to the national average 37.5%). Symptom persistence was not associated with confirmed tick exposure or tick-borne infection. Somatic symptoms were associated with low physical activity and comorbidity. Fatigue and poor physical health were strongly associated with underemployment. Fatigue was also associated with depressive symptoms, low activity, sick leave, and comorbidities. Persistent symptoms were most prevalent in tick-endemic regions but were not associated with prior tick exposure or tick-borne infections. Symptom burden was primarily associated with comorbidities, especially physical inactivity and underemployment. Not applicable.",

The diagnostic approach should verify the accuracy of the initial diagnosis, adherence to and adequacy of antibiotic therapy, and consider potential sequelae or differential diagnoses such as new-onset diseases or comorbidities. When no alternative explanation is found, symptoms may correspond to Post-Treatment Lyme Disease Syndrome (PTLDS), as defined by the French National Authority for Health (HAS). PTLDS is characterized by fatigue, diffuse pain, and cognitive dysfunction lasting more than six months after a documented and adequately treated LB episode. The syndrome significantly impairs daily functioning and quality of life and is not attributable to persistent infection or other identifiable causes. Management relies on long-term, multidisciplinary, and personalized care coordinated between reference centers and primary physicians, focusing on physical rehabilitation and psychological support. Additional antibiotic or immunomodulatory therapies are not recommended due to lack of efficacy and potential adverse effects. Future research should prioritize high-quality clinical studies to clarify therapeutic indications, integrate social science perspectives to better understand the illness and its controversies, and actively involve patients to ensure that research and care strategies align with their lived experiences.",

In Europe, multiple pathogenic species-including B. afzelii, B. garinii, and B. burgdorferi sensu stricto-are responsible for a wide diversity of clinical manifestations. The disease may present in various stages-localized, early disseminated, or late disseminated-depending on the time elapsed since the tick bite and the organs involved, such as the skin, joints, or nervous system. Erythema migrans (EM) is the most frequent clinical presentation, accounting for approximately 80\u00a0% of LB cases in France. It is an early localized form, characterized by a painless, centrifugally expanding erythematous lesion centered on the tick-bite site, typically appearing 3 to 30\u00a0days post-exposure and resolving within 15\u00a0days under antibiotic therapy. Neuroborreliosis (NBL), most commonly associated with B. garinii, occurs in approximately 6-15\u00a0% of French cases. It represents a disseminated form, often presenting as meningoradiculitis or peripheral facial palsy, with generally favorable outcomes under antibiotic treatment, although persistent post-infectious symptoms may occur. These guidelines address the full clinical spectrum of LB, from common manifestations such as EM to rare complications involving cardiac or ophthalmological systems. They also encompass atypical presentations not specifically linked to LB and provide specific recommendations for special populations, including pregnant women and immunocompromised patients. The current section summarizes the principal clinical features of LB and supports the rationale underlying recent diagnostic and therapeutic recommendations.",
        "41333458": "ID: 41333458\nTitle: Toll-like receptor 1 polymorphism is associated with impaired immune tolerance, dysregulated inflammatory responses to Borrelia burgdorferi, and heightened risk of post-infectious Lyme arthritis.\nAbstract: Clinical presentation of Lyme disease is largely due to host immune response to infection. Previously, we identified a variant (1805GG) in the TLR1 gene, a key immune sensor for Borrelia burgdorferi, which was associated with excessive inflammation and severe disease. Herein we examined the mechanism by which this variant leads to dysregulated immunity. We found that patients with post-infectious Lyme arthritis, a condition characterized by marked persistent synovitis in joints, have a higher frequency of TLR1-1805GG compared to those whose arthritis resolves with antibiotics. To explore the possibility that this genotype-phenotype association was due to excessive inflammation, we then tested the functional impact of TLR1-1805GG on inflammatory responses and immune tolerance in PBMCs with or without this SNP and in THP-1 cell lines lacking TLR1. In response to B. burgdorferi stimulation, PBMCs with TLR1-1805GG had greater transcriptional upregulation of ~1200 immune-related genes and significantly higher cytokine levels in supernatants compared to cells without this variant. Moreover, repeat B. burgdorferi stimulation, which mimics tolerogenic conditions during the infection, failed to induce innate immune tolerance in PBMCs with TLR1-1805GG, or in THP-1 cells lacking TLR1, resulting in seemingly unabated immune activation consistent with marked inflammation in Lyme arthritis joints. These results suggest that excessive inflammation in patients with TLR1-1805GG variant appears to be due to immune dysregulation and inability to induce immune tolerance. The findings help explain how early events during the infection may contribute to sustained immune activation after antibiotics and point to the role of TLR1 signaling in immune regulation.",

While Long COVID is newly defined, PAIS have been described for over a century following epidemic infections. Multiple pathogens - including influenza, Epstein-Barr virus, and Borrelia burgdorferi, among others - can precipitate persistent, poorly understood symptoms. Chronic illnesses such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) have long been linked to infectious triggers.

This case highlights the potential risks of dapsone, hydroxychloroquine (HCQ), and rifampin for the management of PTLDS. A 62-year-old female presented to the hospital with shortness of breath and low oxygen saturation. Past medical history included a diagnosis of PTLDS, for which she was prescribed a combination of dapsone, HCQ, doxycycline, rifampin, and ivermectin at home. The patient had an oxygen saturation of 88% on room air but was otherwise clinically stable. Arterial blood gas was obtained and demonstrated an elevated methemoglobin level (11.2%). Analysis of peripheral blood smear revealed oxidative hemolysis, indicating medication-induced methemoglobinemia. Glucose-6-phosphate-dehydrogenase (G6PD) testing was ordered to assess for G6PD deficiency, as this is a known risk factor for methemoglobinemia and had not previously been evaluated for this patient. Testing did not demonstrate a G6PD deficiency for this patient. A negative Lyme total antibody test confirmed no active infection. Both dapsone and HCQ are known to induce methemoglobinemia and the addition of rifampin may enhance this effect. Patient improved on supplemental oxygen, ascorbic acid, and discontinuation of dapsone, HCQ, ivermectin, doxycycline, and rifampin therapy. There is no strong evidence for any anti-infectives used for the treatment of PTLDS, with either short- or long-term use. Dapsone and HCQ can each cause methemoglobinemia. That effect may be increased when used together, especially in combination with rifampin. Appropriate risk assessment and monitoring should be considered when utilizing this combination.",

Post-Acute Sequelae of SARS-CoV-2 Infection (also known as Post-Acute Sequelae of COVID-19 (PASC) or more commonly, Long COVID) occurs in the aftermath of COVID-19 and is poorly understood despite its widespread effects. Methods: We created a machine-learning model that distinguishes PASC from PASC-similar diseases. The model was trained to recognize PASC-dysregulated metabolites (p \u2264 0.05) using molecular descriptors. Results: Our multi-layer perceptron model accurately recognizes PASC-dysregulated metabolites in the independent testing set, with an AUC-ROC of 0.8991, and differentiates PASC from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Lyme disease, postural orthostatic tachycardia syndrome (POTS), and irritable bowel syndrome (IBS). However, it was unable to differentiate fibromyalgia (FM) from PASC. Conclusions: By creating and testing models pairwise on each of these diseases, we elucidated the unique strength of the similarity between FM and PASC relative to other PASC-similar diseases. Our approach is unique to PASC diagnosis, and our use of molecular descriptors enables our model to work with any metabolite where molecular descriptors can be identified, as these descriptors can be generated and compared for any metabolite. Our study presents a novel approach to PASC diagnosis that partially circumvents the lengthy process of exclusion, potentially facilitating faster interventions and improved patient outcomes.",

This issue of Molecular Microbiology contains a comprehensive transcriptomic study that keenly defines the regulatory swath of BosR in the vertebrate host of B. burgdorferi. Despite homology to Fur-like and PurR-like orthologs, BosR has traditionally been linked to regulation of RpoS, the alternative sigma factor that controls the regulon required for establishing a vertebrate infection. However, BosR regulates other genes through an RpoS-independent mechanism, which is elegantly elaborated in Grassmann et\u00a0al., along with clearly demonstrating that BosR does not participate in the defense against oxidative and nitrosative stress in the vertebrate. However, the recently recognized role of BosR as an RNA-binding protein with RNA chaperone activity that regulates gene expression in a post-transcriptional fashion is not wholly appreciated, which clouds the results on determining the DNA-binding site in\u00a0vivo. Regardless, this seminal study enshrines BosR as a major regulator of gene expression in B. burgdorferi and delineates a multitude of BosR-regulated cellular functions in the spirochete related to its ability to navigate between its tick vector and vertebrate host in nature as well as to persist in these two disparate environments.",

We previously identified an essential protein-protein interaction (PPI) event in B. burgdorferi involving two unique proteins, BB0323 and BB0238; herein, we show that this PPI is indispensable for long-term borrelial survival in mammals and explore its potential as a novel target for small molecule therapeutics. Using X-ray crystallography, we solved the structure of the BB0238-BB0323 complex and identified the hotspot residues that form the biomolecular PPI interface area of ~1000 square \u00c5ngstroms. We then performed quantitative high-throughput drug screens of 62,740 diverse small molecules utilizing an amplified luminescent proximity homogeneous assay linked immunosorbent assay (AlphaLISA). Following a comprehensive pipeline to confirm small molecule hits, we short-listed three distinct PPI inhibitors of BB0238-BB0323. One of these inhibitors, called lomibuvir (VX-222, VCH-222), displayed robust PPI inhibition inside B. burgdorferi cells and was shown to affect pathogen persistence in a tick-borne murine model of Lyme disease. Our study highlights targeted PPI disruption as a new therapeutic strategy against B. burgdorferi and may foster future antimicrobial discovery efforts to resolve clinical complications associated with Lyme disease.",

One such infection is caused by Borrelia burgdorferi sensu lato (Bbsl), the spirochete complex responsible for Lyme disease, which can invade the central nervous system (CNS) and trigger Lyme neuroborreliosis (LNB). Bbsl infection is associated with persistent neuroinflammatory responses and immune evasion mechanisms, which may contribute to long-term neurological sequelae in a subset of patients. Neuroinflammation is increasingly recognized as a contributing factor in AD pathogenesis. This review examines proposed mechanistic overlaps between LNB and AD, focusing on the role of Bbsl-induced neuroinflammation driving amyloid-beta (A\u03b2) accumulation and tau pathology. We summarize evidence from in vitro, in vivo, and postmortem studies reporting assay-dependent co-localization of Borrelia with hallmark AD pathology in selected cases, alongside epidemiological studies that yield mixed results. While some studies suggest an association between Bbsl exposure and neurodegenerative risk, others report no clear correlation. Overall, current evidence indicates only an association, and a causal relationship between Bbsl infection and AD has not been established. Understanding this potential link may inform future mechanistic studies, biomarker development, and preventive strategies targeting chronic infection-driven neuroinflammation to address the hypothesis.",

        "41653328": "ID: 41653328\nTitle: Sex and menopause-based differences in presentation of early Lyme disease: A prospective cohort study.\nAbstract: Although prior research has established sex and menopausal status-based differences in immune response, susceptibility, and severity to a variety of pathogens, their relevance in early Lyme disease is understudied. We examined the clinical and serologic presentation of patients with early Lyme disease, stratified first by sex then by menopausal status. We also explored the hypothesis that males would present with more severe early Lyme disease. In this prospective cohort study from the Mid-Atlantic US, 243 adult, antibiotic-na\u00efve patients were enrolled with a diagnostic erythema migrans rash present. Demographic, physical exam, symptom, laboratory, and two-tier serology data were collected at a baseline, and a post-treatment visit 3 weeks later. Lyme disease severity was operationalized through six indicators: rash size, number of acute symptoms, dermatologic dissemination, positive serology, liver function elevation, and elevated neutrophil-lymphocyte ratio. Unadjusted group comparisons and multivariate regression adjusting for potential confounders were used to assess difference. In logistic models adjusted for age, Lyme disease duration, systemic steroid use, and co-morbid thyroid disease, males had higher odds of testing two-tier positive (OR\u2009=\u20091.77 [1.03, 3.04], p\u2009=\u20090.039). This difference was more pronounced between males and pre-menopausal females (OR\u2009=\u20092.93 [1.26-6.79], p\u2009=\u20090.012) and no significant difference was found comparing males to post-menopausal females. In ordinal logistic models with Lyme disease severity as the outcome adjusted for age and Lyme disease duration, males had higher odds of being in a higher disease severity score category (OR\u2009=\u20091.94 [1.20,3.15], p\u2009=\u20090.028); again, particularly in comparison to pre-menopausal females (OR\u2009=\u20092.26 [1.13,4.58], p\u2009=\u20090.044). Heart palpitations (p\u2009=\u20090.023), vomiting (p\u2009=\u20090.007), and photophobia (p\u2009=\u20090.057) trended towards higher reporting among females, while sleep difficulty (p\u2009=\u20090.010) was higher among males. No differences were found on non-dermatologic components of the physical exam.\u00a0We found sex and menopausal status to be relevant in accounting for variability in two-tier serologic status and severity of early Lyme disease in a well-characterized group of patients. Lower rates of seroreactivity among females is unexpected but may be consistent with lower acute severity of disease. Our clinical findings underscore the need for additional research to understand possible contributing biologic and/or social behavioral factors, as well as their impact on timely diagnosis and post-treatment conditions. Lyme disease is a bacterial infection obtained through a tick bite. The goal of this study was to look at whether male and female patients with early Lyme disease show up to the doctor with different signs of their disease in terms of the symptoms they report, their physical exams, and the results of their laboratory tests. We also examined whether females who had gone through menopause would be different on these factors compared to those who had not. We studied data from 243 adults (118 females and 125 males) with early Lyme disease before and after treatment. We found that at diagnosis, males were more likely to have a positive test and more obvious findings of severe disease, yet there were no differences in how long males and females had been sick. For both of these findings, the male group was more similar to females who had undergone menopause and was more different than females who had not. We found a small number of Lyme disease symptoms that were reported more frequently among females (heart palpitations, vomiting, eyes sensitive to light, neck pain, nausea) and two symptoms (sleep difficulty and irritability) reported more frequently among males. These findings suggest that sex and menopause status are important to consider in understanding early Lyme disease. More research is needed to determine the cause of these differences and their impact on time to diagnosis and risk of later conditions after treatment.",

Laboratory investigations have demonstrated marked disparities in infection responses among distinct mouse strains: C57BL/6 mice have mild arthritis and rapid tissue repair, whereas C3H mice exhibit severe arthritic manifestations. Comparing these strains has helped identify genetic and immune factors important for arthritis development. In this study, female C57BL/6 and C3H mice were inoculated with Bb via bilateral footpad injection. Disease progression was evaluated through multidimensional parameters, including joint swelling measurements, radiographic examinations, and histopathological analyses at acute (14 days) and chronic (56 days) phases. RNA-seq of joint tissue, combined with single-sample gene set enrichment analysis, immune deconvolution, and multi-omics enrichment revealed strain-divergent signatures. The experimental data unveiled strain-specific immune response patterns: C3H mice exhibited persistent inflammatory responses characterized by heightened complement system activation, sustained inflammatory mediator expression, and prolonged inflammasome activity. C57BL/6 mice maintained relatively stable inflammatory mediator levels and immune homeostasis. Transcriptomic analysis revealed 2,183 (C3H) and 439 (C57BL/6) differentially expressed genes on day 14 post-infection, encompassing processes related to immune cell recruitment, cytokine networks, and complement activation. These findings illuminate the regulatory role of host genetic background in temporal characteristics of immune responses, providing novel molecular insights into differential susceptibility to LA.",

Adults presenting with new conduction disorders and scheduled for permanent pacing were enrolled and provided serum at baseline and 4-week follow-up. Anti-Borrelia immunoglobulin (Ig)G was assessed using a two-tier algorithm (enzyme-linked immunosorbent assay screening, immunoblot confirmation). Probable Lyme carditis was defined as IgG seroconversion or stable/rising titers; no Lyme carditis was defined as persistent seronegativity or declining titers. Of 80 enrolled patients, 74 completed follow-up (92.5%; mean age 71.6 years; 68.9% male). Third-degree atrioventricular block was most frequent (56.8%). Probable Lyme carditis was identified in eight of 74 (10.8%) patients. Of 14 patients who were enzyme-linked immunosorbent assay-reactive/borderline, six (42.9%) were immunoblot-negative. Seropositive patients were older (age 76.3 vs 71.1 years); titers were higher in men at 4 weeks. IgG positivity was associated with suspected Lyme carditis (relative risk 6.8 at baseline; 16.2 at 4 weeks). No participant reported a recent tick bite or erythema migrans. Approximately one in 10 pacemaker candidates showed serological patterns compatible with probable Lyme carditis. Incorporating two-tier paired serology into evaluation of high-grade conduction disorders in endemic settings may improve etiologic diagnosis and inform management.",
        "41770041": "ID: 41770041\nTitle: The lp17 regulatory elements in Borrelia burgdorferi: a novel small RNA impacts gene expression and mammalian infection.\nAbstract: The segmented genome of Borrelia burgdorferi, the tick-borne agent of Lyme disease, encodes numerous chromosomal and plasmid-borne proteins and small RNAs (sRNAs) of unknown function that are critical for infectivity. Two recent examples are the linear plasmid (lp)17-encoded protein BBD18 and sRNA SR0736 (also termed as ittA), which promote spirochete survival in ticks and mammals, respectively. Using targeted mutagenesis of the bbd18 locus, complementation, and phenotypic analysis of isogenic mutants, we herein confirm and extend the regulatory roles of BBD18 and SR0736 (ittA). A mutant lacking BBD18 and SR0736 (ittA) persisted in ticks, yet failed to infect immunocompetent or immunodeficient mice. Although bbd18 complementation selectively restored bbd18 expression, it did not rescue murine infectivity, supporting an essential role for SR0736 (ittA) during mammalian infection. Transcriptomic and proteomic analyses revealed widespread alterations in expression profiles that were only partially rescued by bbd18 complementation, suggesting distinct regulatory functions for BBD18 and SR0736 (ittA). Because an additional sRNA (SR0735) lies immediately downstream relative to bbd18, we generated an isogenic SR0735 inactivation mutant, which was likewise largely noninfectious in mice and exhibited dysregulation of multiple gene products, including the induction of several lp17 genes, such as bbd18, and the downregulation of multiple proteins, such as OspC, BamA, and DbpA. Together, these data indicate that the bbd18 locus is surrounded by two essential sRNA elements, SR0735 and SR0736 (ittA), all three of which independently regulate genes, including ones impacting mammalian infectivity. Further characterization of such atypical regulatory elements in B. burgdorferi may inform new control strategies. Borrelia burgdorferi, the tick-borne agent of Lyme disease, is the causative agent of one of the most prevalent vector-borne infections in many regions worldwide. Despite extensive study, the biological functions of many of its protein and small RNA (sRNA) products remain poorly defined. Here, we confirm and extend the regulatory roles of the linear plasmid (lp)17-encoded protein BBD18 and the sRNA SR0736 (ittA) in spirochete infectivity. Importantly, we identify a previously unrecognized regulatory function for an adjacent sRNA, SR0735, underscoring lp17 as a key regulatory region in B. burgdorferi. Together, our findings highlight the bbd18 locus and its surrounding sRNA elements as an independent, multilayered regulatory module that controls gene products, including those required for mammalian infection. Defining how these three regulators shape gene expression and virulence will reveal new mechanisms underlying Lyme disease pathogenesis and may inform the development of new strategies to prevent this widespread illness.",

Neurodegenerative diseases, including Alzheimer's and Parkinson's, are a growing global health concern. While age remains the primary risk factor, infectious agents have been proposed as potential contributors to disease onset or progression.Gap statement. Spirochaetal bacteria, such as Treponema pallidum, Borrelia burgdorferi and Leptospira spp., can invade the central nervous system, yet the extent to which these infections influence neurodegenerative outcomes remains unclear.Aim. This systematic review aimed to evaluate observational evidence on the association between spirochaetal infections and neurodegenerative diseases and to identify gaps in the literature to inform future research.Methodology. A systematic search of SCOPUS, EMBASE, PubMed/MEDLINE, Web of Science and CINAHL was conducted for studies published between January 2000 and May 2025. Eligible studies were observational, involved adult human populations and reported both spirochaetal infection and cognitive or neurodegenerative outcomes using standardized methods. Data were extracted using a standardized form. Owing to heterogeneity in study design, diagnostic approaches, outcome measures and reporting formats, an overall pooled meta-analysis was not feasible; however, a quantitative synthesis using meta-analytic methods was conducted for studies reporting mini-mental state examination data. Risk of bias was assessed using the Newcastle-Ottawa Scale.Results. Twenty-seven studies met the inclusion criteria: 13 on T. pallidum, 13 on B. burgdorferi and one on Leptospira spp. No eligible studies were found for Brachyspira spp., and studies involving Treponema denticola were excluded due to confounding by periodontitis. Studies investigating syphilis and leptospirosis consistently reported cognitive impairment and increased dementia risk. In contrast, findings for Lyme disease were heterogeneous, with some studies reporting persistent symptoms or increased Alzheimer's risk, while others found no long-term cognitive effects.Conclusion. This review highlights a potential link between spirochaetal infections and neurodegenerative outcomes, particularly for syphilis and leptospirosis. Evidence for Lyme disease remains inconclusive. Future research should prioritize longitudinal studies with standardized diagnostic criteria, integration of neuroimaging and biomarker data and improved diagnostic accuracy for spirochaetal infections.",

Significant improvements were observed in pain levels, as indicated by the SF-36 pain scale (t[11] = -3.19, p\u202f=\u202f0.01, d = -0.92), and pain interference significantly decreased during daily activities, as measured by the BPI (t[11] = 2.61, p\u202f=\u202f0.02, d = 0.75). Participants also reported fewer physical limitations during personal activities (t[11] = -2.46, p\u202f=\u202f0.03, d = -0.71; SF-36). Cognitive improvement was indicated by a significant reduction in errors on the CANTAB Spatial Working Memory task (t[8] = 3.11, p\u202f=\u202f0.02, d = 1.04). Online yoga is feasible and associated with significant reductions in pain, improved physical functioning, and enhanced cognitive performance among participants with PTLDS. These findings suggest that online yoga may be a scalable, accessible, and effective intervention for managing PTLDS symptoms.",

It is therefore expected that treatment with either product prevents Lyme infections due to their efficacy against I. scapularis ticks before the anticipated transmission of Borrelia burgdorferi by infected ticks. In total, four laboratory studies were conducted in which dogs were randomly allocated to two treatment groups of 10 dogs each. On day 0, dogs were either administered a placebo treatment (Pet-Tabs\u00ae Palatable Vitamin-Mineral Supplement for Dogs), Simparica TRIO tablets at the minimum dose of 1.2\u00a0mg/kg sarolaner, 24\u00a0\u03bcg/kg moxidectin and 5\u00a0mg/kg pyrantel (study 1 and 2) or Simparica at the minimum dose of 2\u00a0mg/kg sarolaner (study 3 and 4). On post-treatment day 28, each dog was infested with approximately 50 unfed, wild-caught adult I. scapularis ticks with a high B. burgdorferi infection rate. Blood samples were collected from each prior dog to treatment and on post-treatment days 27, 49, 63, 77, 91 and 104, and qualitatively tested for B. burgdorferi antibodies using the SNAP\u00ae 4Dx Plus and Lyme Quant C6\u00ae antibody tests. Four skin biopsies from each dog were collected on day 104 from the most common areas of tick attachment and tested by PCR for the quantitative presence of B. burgdorferi. In all studies, at least nine out of 10 placebo-treated dogs were infected with B. burgdorferi before the end of the study. In study 1, one Simparica Trio-treated dog tested positive, whereas in the other studies none of the dogs treated with sarolaner tested positive at any time point during the study. Both Simparica and Simparica Trio at the minimum label dose prevent the transmission of B. burgdorferi infections as a direct result of killing the I. scapularis vector ticks.",

When these symptoms are unexplained by other conditions and persist for \u2265\u20096 months, this condition is called post-treatment Lyme disease symptoms or syndrome (PTLDS). The pathogenesis of PTLDS is unknown and no specific diagnostic biomarkers have been identified. In this study, we used a high-density peptide array to examine antibody responses to >\u200960 primary antigens of B. burgdorferi from a cohort of patients diagnosed with PTLDS and recovered patients with similar Lyme disease manifestations. Using matched serum and cerebrospinal fluid (CSF), we mapped the primary reactive B. burgdorferi epitopes associated with PTLDS. We found that VlsE had a greater antibody response within the PTLDS cohort than recovered patients. The reactivity to OspC-specific epitopes revealed a predominance of antibodies to OspC type K and A in the PTLDS cohort. However, the major immunodominant epitopes were similar in PTLDS and recovered patients, and we were unable to identify specific diagnostic targets for PTLDS. We found a more robust reactivity in the serum over CSF and did not identify antigenic regions that were specifically associated with the infection of the central nervous system.",

The combination of selamectin plus sarolaner (Revolution\u00ae Plus/Stronghold\u00ae Plus; Zoetis; RP) is effective against Ixodes spp. for 1 month. The objective of this study was to determine whether RP protects cats against transmission of B. burgdorferi from Ixodes scapularis by killing the ticks before transmission occurs. Transmission of A. phagocytophilum was also monitored. Ten cats per group were treated once topically either with placebo solution (0.1\u00a0ml/kg) or with the minimum label dose of RP (6.0\u00a0mg/kg selamectin plus 1.0\u00a0mg/kg sarolaner). Thirty days post-treatment, cats were infested with 50 wild-caught adult I. scapularis. Ticks were counted, categorized, and removed on day 35. Blood collections for serology occurred on days -6, 30 (prior to infestation), 49, 63, 77, 91, and 104. Serum antibody assay results (B. burgdorferi and A. phagocytophilum) and polymerase chain reaction (PCR) of skin biopsies (B. burgdorferi) were used to define infection rates in the cats. Treatment with RP resulted in a 100% reduction of I. scapularis ticks compared with placebo-treated cats. In placebo-treated cats, antibodies against B. burgdorferi, A. phagocytophilum, both agents, and B. burgdorferi DNA in skin (five, nine, six, and three cats, respectively) were detected by day 104. In contrast, none of the RP-treated cats developed B. burgdorferi antibodies or DNA in skin biopsies, and A. phagocytophilum antibodies were detected in only two cats, significantly lower than in placebo-treated cats. Results suggest that a single application of RP at the minimum label dose reduces the risk of infection by both B. burgdorferi and A. phagocytophilum, when infected at the end of the dosing interval.",
        "41859106": "ID: 41859106\nTitle: Treponema pallidum TprD and TprK are adhesins and their surface expression promotes spirochetal opsonophagocytosis.\nAbstract: Treponema pallidum subspecies pallidum causes systemic syphilis, exclusively infects humans in nature and can persist for decades in the absence of treatment despite generating robust adaptive immune responses. The T. pallidum repeat (Tpr) family of outer membrane proteins are immunogenic and are implicated in immune evasion, indicating them to be virulence factors displayed on the spirochete surface. Long-term survival of T. pallidum is largely attributed to sparse surface-exposed outer membrane proteins and antigenic variation in the major surface protein TprK through phase variation. This mechanism has been studied for decades; however, the functions of Tprs of this extracellular pathogen are not yet experimentally determined. In this study, the localization and functional roles of TprD and TprK were investigated using a heterologous spirochete expression system and a gain-of-function approach by employing a non-infectious, non-adherent Borrelia burgdorferi B314 strain. Opsonophagocytosis of engineered B. burgdorferi as well as of T. pallidum Nichols and SS14 strains was evaluated using J774A.1 macrophages and mouse antibodies raised against predicted surface-exposed loops of TprD and TprK using IncuCyte system. Both TprD and TprK were found to be surface exposed in engineered B. burgdorferi and infectious T. pallidum strains. Expression of these proteins conferred adherence to several mammalian cell lines in vitro. In addition, antibodies we generated recognized TprD and TprK on the surface of spirochetes and significantly enhanced macrophage-mediated opsonophagocytosis. Our findings here demonstrate that TprD and TprK function as T. pallidum adhesins that are also targets of opsonic antibodies. These Tprs likely facilitate tissue colonization during infection, while also rendering the pathogen susceptible to immune clearance. Our findings support inclusion of TprD and TprK as components of a multivalent vaccine against syphilis.",
        "41888159": "ID: 41888159\nTitle: Lyme borreliosis.\nAbstract: Lyme borreliosis is the most common tick-borne disease in the northern hemisphere. It is a zoonosis caused by several species of Borrelia burgdorferi sensu lato and transmitted by the bite of infected ticks of the Ixodes ricinus complex. Lyme borreliosis in North America and Europe differs in certain respects, likely reflecting the different Borrelia species that cause human disease in these locations. The earliest manifestation of Lyme borreliosis is the skin lesion erythema migrans, which develops at the tick\u00a0bite site, typically 7-14 days after the bite. Some untreated patients will then (within the first few weeks or months after onset of the infection) develop additional erythema migrans skin lesions or other clinical manifestations such as borrelial lymphocytoma, nervous system involvement or carditis. Several months or even years after infection onset, Lyme arthritis or acrodermatitis chronica atrophicans may develop. The diagnosis of typical erythema migrans is clinical, whereas for all other manifestations\u00a0the diagnosis is supported via serological testing. Treatment with an appropriate antibiotic will result in resolution of clinical symptoms in most patients; however, some patients experience prolonged subjective symptoms, which usually improve over time. Repeated courses of antimicrobials are not beneficial except in rare cases when there is objective evidence of treatment failure.",

Transmitted borrelia can occupy any organ where it causes a silent inflammation, which in sensitive persons is intermittently repeated chronically. The aim of this paper was to determine how much Borrelia burgdorferii participates in the occurrence of chronic urticaria in children and adults. In the 13-year period from January 1, 2013 to December 31, 2025, a study of all manifestations of Lyme borreliosis was conducted on a sample of 1,059 patients, treated and monitored in the Private practice of an infectious disease specialist. The research was retrospective-prospective, descriptive, clinical and analytical. It was carried out in three phases: the first retrospective phase and the second two prospective phases. The diagnosis of LB was established on the basis of anamnestic-epidemiological data, clinical picture, clinical findings of new borreliosis markers and performed examinations. Serological confirmation of borreliosis was done using ELISA, WB and Immunoblot methods, as well as the ex-yuvantibus method, and in the last six months of 2025, additionally, the finding of bacteria Borreliosis in a dark field with a light microscope. The results showed that 92.1% of the patients in the study group had intermittent migratory redness with itching. In the majority of patients, redness was without exudation or with little or no exudation. In 4.8% of patients, typical urticarial changes were found that occurred occasionally or daily. In all subjects, we serologically confirmed the presence of Borrelia burgdorferi. All patients had intermittent itching of the skin, which lasted for years. Based on the results, it can be concluded that Borrelia burgdorfrii is one of the most important factors in the development of chronic urticaria in monitored patients with 96.9%. Due to its persistence in the macroorganism, it causes reduced tolerance to food. Only 3.1% of cases of urticaria are caused by some other factors. In all cases of chronic urticaria, new clinical markers should be sought on the patients' skin. Serologically look for antibodies to Borrelia protein sequences in an immunoblot. In the active phase, look for Borrelia with a light microscope in the dark field. Administer antibiotic therapy together with antihistamines. Exclude food to which the intolerance test confirmed hypersensitivity greater than \"2\".",

Millions of Americans are affected by these debilitating, misunderstood conditions, which share symptom profiles and pathophysiologic abnormalities. IACCI have received insufficient clinical attention and research investment.

Here, we evaluated in silico the predicted binding affinities of 192 HLA-II alleles with all 15-mer peptide sequences of five Borrelia burgdorferi proteins to identify peptides with strong binding affinity, as they would be the best candidates for antibody production in response to vaccination. We found the following: (a) 226 of the 1067 peptides tested (21.2%) were found to bind strongly to HLA-II molecules; (b) decorin-binding protein A had the greatest number of strongly binding peptides; and (c) 69 HLA-II alleles (primarily of the DRB1 gene) bound with strong affinity to peptides from Borrelia burgdorferi proteins. Finally, we tested for possible susceptibility to autoimmunity by any one of the 226 peptides above by searching for their occurrence in ~84,000 proteins of the human proteome and found overlap with only two 8-mer peptide sequences (embedded within the 226 15-mer peptides), neither of which was characterized by strong binding to HLA-I, suggesting a reduced likelihood of autoimmunity. These findings emphasize the importance of a personalized vaccine approach based on the vaccinee's human leukocyte antigen genetic makeup and offer specific vaccine-candidate peptides that are predicted to maximize vaccine effectiveness and safety. The results of this computational study provide novel directions for future development of Lyme vaccines.",

Although B. burgdorferi has a streamlined genome and minimal virulence repertoire, it establishes persistent infection through coordinated modulation of mammalian host immune responses. Here, we synthesize recent advances in the immunobiology of B. burgdorferi using a stage-structured framework that traces a tick-mediated vertebrate infection through systemic dissemination, tissue colonization, and chronic immune engagement. Emphasis is placed on post-2020 insights enabled by intravital imaging, single-cell transcriptomics, spatial profiling, and systems immunology, which have refined our understanding of endothelial transmigration, tissue-specific immune conditioning, disruption of germinal center responses, and failure of sterilizing immunity. We highlight how antigenic variation at the vls locus, complement evasion, and coordinated adhesin networks support dissemination and long-term tissue residency, while adaptive immune responses are redirected toward extrafollicular, non-sterilizing trajectories. These immune strategies differentially shape infection outcomes across host species, supporting asymptomatic persistence in reservoir hosts while driving inflammatory disease in humans. The review further examines antigen persistence, immune stalemate, and post-treatment inflammatory sequelae, integrating translational advances in diagnostics and prevention. By integrating an ecological context with mechanistic immunology and clinical insight, this review presents a contemporary framework for understanding how immune modulation by B. burgdorferi across spatial and temporal scales shapes host-pathogen coevolution and informs improved diagnostic strategies, vaccine development, and therapeutic intervention.",

We analyzed the reservoir host's local and systemic immune responses to Bb during tick feeding. C3H/HeN mice were challenged via infected or uninfected nymphal Ixodes scapularis ticks or by subcutaneous injection of cultured multi-strain Bb. Skin and spleen tissues were evaluated by flow cytometry, serum was evaluated by cytokine proteome array, and all data were analyzed by comparison between each of the three challenged groups against the subcutaneously inoculated PBS control. Flow cytometry profiling shows that neutrophils, Langerhans cells, macrophages, B cells, and Natural Killer cells were mobilized in the three challenged groups in the skin and spleen, dendritic cells were increased in tick-transmitted groups, and T cells were engaged in Bb-challenged groups. Regarding soluble chemotaxis mediators in blood, all chemokines and cytokines induced by subcutaneously delivered Bb and uninfected tick were also induced by tick-transmitted Bb. However, tick-transmitted Bb induced unique factors absent in the other groups, which included chemokines involved in recruitment of phagocytic cells and T cell engagement, and cytokines associated with broader T cell activation. Regarding anti-inflammatory mediators, although IL-1ra was increased in the three challenged groups, IL-10 was only increased in tick-challenged groups with or without Bb. The data suggest that tick-transmitted Bb induced much more dynamic but regulated immune responses during tick-feeding, compared to subcutaneously delivered Bb, which may explain Bb persistence in the reservoir host.IMPORTANCECurrent knowledge on immune cell interactions with Borrelia burgdorferi (Bb) derives mostly from studies done in vitro and ex vivo, which cannot assess host immunity to natural tick-delivered Bb within the complex architecture of host tissues. We report the first in vivo study on local and systemic immune responses to Bb during tick feeding on a surrogate reservoir host, in comparison with uninfected-tick and subcutaneously delivered Bb. We show that uninfected-tick and tick-transmitted Bb engaged mixed type-1/type-2/type-17 immune responses in the presence of anti-inflammatory IL-10, in contrast to a type-1 response induced by subcutaneously delivered Bb. Analyses of immune responses to tick-transmitted Bb in a reservoir host can enlighten immunity mechanisms that mediate persistence of Bb.",

Borrelia burgdorferi is well established in the mid-Atlantic, whereas Babesia microti and Anaplasma phagocytophilum remain patchily distributed. Five years of integrated surveillance (2020-2024) at three Maryland sites allowed us to track B. microti and A. phagocytophilum establishment by screening questing Ixodes scapularis nymphs, Peromyscus leucopus-fed nymphs, and P. leucopus samples by qPCR, contextualized with county-level human case data. B. burgdorferi was consistently detected in all sites and sample types, with prevalence generally 5%-20% in questing nymphs and exceeding 30% in hosts, confirming long-term enzootic maintenance. By contrast, B. microti and A. phagocytophilum were initially sporadic but increased in rodents and P. leucopus-fed ticks. Over time, A. phagocytophilum prevalence significantly increased to above 20% in some P. leucopus-fed nymphal collections despite much lower prevalence in questing ticks, highlighting the early-warning value of blood meal-associated surveillance. Notably, B. microti reached very high prevalence in P. leucopus hosts at a specific site (up to ~80%) while remaining rare or absent in questing and engorged nymphs, highlighting a pronounced decoupling between host infection and vector prevalence. Coinfections were rare, though enrichment of B. burgdorferi + A. phagocytophilum in P. leucopus-fed ticks suggests possible facilitation during early establishment. These results indicate that B. microti and A. phagocytophilum are actively emerging in Maryland, following their establishment in the Northeast and Upper Midwest. Combining surveillance from questing nymphs, P. leucopus-fed nymphs, and reservoir hosts provides a framework for detecting enzootic cycles before they appear in questing ticks or human case counts, offering early-warning capacity for public health preparedness.IMPORTANCEUnderstanding why some tick-borne pathogens become ecologically established while others remain sporadic is central to predicting human disease emergence. By combining surveillance of questing nymphal Ixodes scapularis ticks, Peromyscus leucopus-fed nymphal ticks, and Peromyscus leucopus reservoir hosts across 5 years in Maryland, we show that Babesia microti and Anaplasma phagocytophilum remain in the early stages of enzootic establishment, whereas Borrelia burgdorferi is deeply established. This integrated approach demonstrates how pathogen biology within the tick shapes field prevalence and highlights P. leucopus-fed ticks as a powerful xenodiagnostic early-warning tool for detecting emerging pathogens before they are reflected in questing populations or human case data.",

This review summarizes current knowledge on the pathogen-host interactions and immune responses. Early infection can be influenced by tick saliva, which suppresses local host defense and promotes spirochete survival, and by pattern recognition receptors activating proinflammatory cascades. Bbsl employs a variety of immune evasion strategies, notably impairing antigen presentation-through disruption of MHC II and IFN-\u03b3 pathways-and continuously varying surface antigens to hinder long-lasting antibody formation. Autophagy plays a central role in modulating inflammation and T helper 17 adaptive immune responses, representing an underappreciated mechanism potentially influencing disease outcome. Adaptive immunity in LB is characterized by robust but often dysregulated humoral and cellular responses, with transient germinal centers and enduring IgM production contributing to incomplete pathogen clearance. Persistent immune defects include impaired long-term B cell memory, suppressed T cell activation, and ongoing immunosuppression after pathogen clearance. Similar patterns are observed in other postinfectious fatigue syndromes. Despite advances, gaps remain in understanding mechanisms of Bbsl persistence and the immunopathology underlying chronic disease, challenging diagnosis and therapy. Emerging molecular and cellular approaches offer new avenues to address immunity, diagnostics, and prevention. A multidisciplinary effort will be needed to improve long-term patient outcomes in the evolving epidemiology of LB.",

This review focuses on several diseases representative of the IACI spectrum. These are post-treatment Lyme disease syndrome (PTLDS), long COVID, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and multiple sclerosis (MS). Their clinical and biological complexity, combined with a lack of clear diagnostic criteria and objective available laboratory biomarkers, makes them difficult to distinguish from conditions with overlapping features. This presents challenges for research studies, as well as diagnosis and clinical management. This diagnostic ambiguity, coupled with heterogeneous patient presentations, has led to challenges in research, including misclassification of study participants and inconsistent or irreproducible findings. Some PTLDS research exemplifies these issues, which also extend to other IACIs. To advance the field, we highlight key methodological refinements and approaches for studying IACIs, including rigorous participant selection, standardized sample collection protocols, and the use of appropriate control groups, including those with microbiologic proof of the initial infection when known and technologically feasible. We also address broader influences on research quality, such as stigma, historical neglect, and the urgency to find treatments, which have contributed to the proliferation of poorly controlled studies and questionable practices. Drawing lessons from past challenges, we propose a path forward grounded in fit-for-purpose methodological rigour to improve scientific understanding and support evidence-based therapeutic development for IACIs.",

The bacterial determinants underlying this phenotypic variation remain largely unknown, limiting our ability to predict disease progression and optimize treatment strategies. Here, we applied machine learning (ML) approaches to identify specific amino acid residues within surface-exposed virulence factors that predict human dissemination phenotypes. Utilizing the published whole genome sequences from 299 clinical Borrelia burgdorferi isolates collected from the United States and Slovenia over a 30-year period (1992-2021), we extracted and characterized translated amino acid sequences (variants) of seven known virulence factors (BB_0406, BBK32, DbpA, OspA, OspC, P66, and RevA). Protein variants were classified based on their association with disseminated versus localized infections using clinical metadata. Cram\u00e9r's V analysis revealed possible strong associations between dissemination phenotypes and five adhesins: BBK32, DbpA, OspC, P66, and RevA. We developed ML models using five algorithms with multiple feature selection strategies, achieving robust predictive performance for DbpA, OspC, and RevA variants (all performance metrics\u2009>\u20090.7). Feature importance analysis identified 57, 29, and 42 key predictive residues for DbpA, OspC, and RevA, respectively. Notably, B-cell epitope prediction revealed significant enrichment of ML-identified residues within predicted epitope regions for OspC (11 overlapping residues, OR = 3.57, p\u2009=\u20090.006) and RevA (12 overlapping residues, OR = 2.37, p\u2009=\u20090.048), suggesting these residues may influence immune recognition and bacterial persistence.

Gastrointestinal (GI) symptoms are frequently reported, yet their relationship to central features of the illness and biological correlates remains poorly understood. We aimed to characterize GI symptom burden in ME/CFS and evaluate its associations with core clinical features and specific immune and inflammatory markers, with attention to potential gut-related contributions to disease expression. GI symptoms and 49 additional symptoms across nine domains were assessed in 116 ME/CFS patients and 80 matched controls. Plasma C-reactive protein (CRP) and antibodies against dietary and microbial antigens were measured as indicators of systemic inflammation and putative gut-derived antigen exposure. ME/CFS patients reported significantly elevated GI symptom frequency and severity compared with controls, with 53% of ME/CFS patients versus 8% of controls reporting a prior diagnosis of irritable bowel syndrome. GI symptom burden correlated with fatigue, cognitive difficulties, flu-like symptoms, pain, sleep disturbances, neurological complaints, and sensory sensitivities, independent of illness duration. CRP levels were higher in patients with greater GI symptoms and correlated with GI, fatigue, musculoskeletal pain, and flu-like symptom burden. Patients with greater flu-like symptom expression exhibited higher IgM responses to dietary gliadin and bacterial lipopolysaccharide. These associations were not detected in controls. GI symptoms are a prominent, clinically relevant dimension of ME/CFS, associated with broader symptom burden and inflammatory heterogeneity. These findings highlight the relevance of gut-related and immune processes in ME/CFS and underscore the value of incorporating GI symptom assessment in translational studies to help refine mechanistic understanding and improve therapeutic stratification.",

Heightened incidence levels of LD have been recorded in parts of Europe, Poland, Eastern Europe, and the Baltic States. The research aimed to inform the cost of LD and post-treatment Lyme disease syndrome (PTLDS) in Ireland through results from a patient questionnaire, disease modelling, the construction of a patient roadmap, and attempts to arrive at prevalence calculation estimates based on local data. Patient data encompassed sociodemographic particulars, disease attributes, healthcare resource utilization, and the influence on their employment status. Of 301 patients, 210 were diagnosed with LD and/or a tick-borne infection (TBI), the cohort's average age was 40.07 (SD 13.5) (N\u202f=\u202f210; Female:Male 60:40). The mean duration of symptoms in PTLDS patients was 7.15\u202fyears. The average number of visits to other healthcare professionals was 16.8 per patient. Regarding current employment status, the data indicates that 50.2% of respondents were currently working, 10.1% were unemployed, 8.7% were retired, 5.3% had caring responsibilities, 11.1% were on sick leave, and 14.5% fell into the \"Other\" category. Additionally, when asked if symptoms had affected their employment status, 69% of respondents said yes, 26% said no, and 5% did not respond. Modeling efforts show that the roadmap to care for PTLDS is challenging, leading to wandering from specialty to specialty and high healthcare utilization. Utilizing a novel method of indirect reverse estimation, our lifetime risk or cumulative incidence of PTLDS estimation is at 0.003%. Lack of data collection from Irish health authorities is leaving the issue of the cost of LD and PTLDS hard to address, despite efforts from our single-site study.",

Increasing evidence suggests that immune dysregulation-including persistent inflammation, autoantibody production, and cellular immune dysfunction-may underlie these conditions. This narrative review synthesizes peer-reviewed literature describing immune abnormalities across these syndromes and evaluates the rationale for immunomodulatory therapies, including intravenous immunoglobulin (IVIG), rituximab, and therapeutic plasma exchange (TPE). Evidence supporting immune-targeted treatment strategies is strongest in subsets of patients with identifiable immunologic abnormalities. Notably, the phase III RituxME trial in ME/CFS and a phase II trial of TPE in post-COVID condition both failed to demonstrate efficacy in unselected populations, reinforcing the importance of biomarker-guided patient stratification. TPE functions by removing circulating immune complexes, autoantibodies, and inflammatory mediators, and observational data suggest benefit in patients with demonstrable autoantibody burden. Further controlled studies incorporating immunologic phenotyping and early intervention are needed to define the therapeutic role of immune-directed interventions across these conditions.",

Among 223 children, 61.9% were male and the mean age was 6.99 years. Quality-of-life scores varied markedly across domains. Daily activities, school activities, movement and balance, eating activities, and speech and communication showed wide score dispersion, whereas pain and fatigue showed ceiling effects. Scores declined progressively with increasing Gross Motor Function Classification System level across analysed domains, with strong monotonic trends observed (Kendall's \u03c4\u2009-\u20090.57 to -\u20090.72; all p\u2009<\u20090.001). Epilepsy, cognitive impairment, cortico-visual impairment, hearing impairment, and gastro-oesophageal reflux disease were associated with lower overall or domain-specific scores in unadjusted analyses. In adjusted models focused on measured social factors, age, sex, living arrangement, and parental education were not independently associated with the analysed domain scores. Domain-level assessment may provide clinically informative quality-of-life profiles that are not captured by overall scores alone.",

To date, suicide prevention attitude measures are limited by appropriate population use, poor psychometrics and a lack of theoretical foundation. The present study rectified a measurement gap in the literature by articulating initial development of the Inventory of Clinician Attitudes about Suicide Prevention (ICASP). MHPs (N\u2009=\u2009410) across three countries (United States, Canada and Australia) took part in a cross-sectional online survey about suicide prevention competencies. A community-engaged convenience sampling approach was used followed by splitting the sample to perform parallel exploratory factor analysis and item response theory analyses. Analyses yield a four-factor ICASP with 22 items: (1) Clinician's Approach (\u03c9\u2009=\u20090.79); (2) Clinician Avoidance (\u03c9\u2009=\u20090.76); (3) Moral Rights (\u03c9\u2009=\u20090.84); and (4) Clinician Comfort (\u03c9\u2009=\u20090.72). Exploratory findings suggest convergent validity via significant, yet modestly sized, correlations with attitudes glorifying suicide and three elements of compassion fatigue (i.e. compassion satisfaction, burnout and secondary traumatic stress). The ICASP represents a promising tool for measurement of MHP suicide prevention attitudes in clinical supervision, self-reflective practice and training evaluation. Findings support portions of the Dynamic Balance Model of MHP suicide prevention attitudes. Future psychometric research directions are discussed.",

Microbreaks have emerged as a potential ergonomic intervention to reduce discomfort and fatigue during surgery.ObjectiveThe main goal of this study was to investigate and compare the intraoperative usability and effectiveness of two break scheduling strategies using the OR-StretchTM Web-App. Furthermore, surgeons' feedback on the primary barriers to implementation of the OR-Stretch Web-App was recorded.MethodsThis study used a randomized, within-subjects crossover design. Fourteen surgeons (eight females) performed three surgical procedures with the following microbreak schedules; (1) microbreaks every 30\u2005min with an optional ten-minute snooze (Break-30), (2) microbreaks every 60\u2005min with an optional ten-minute snooze (Break-60), or (3) no microbreaks (Baseline). Outcomes were measured using self-reported subjective surveys (e.g., discomfort, fatigue, workload, and usability).ResultsSurgeons found both Break-30 and Break-60 conditions aided physical performance, mental focus, body pain/discomfort, and level of fatigue (self-reported improvement between 28.6% and 78.6%). No significant differences were observed in surgeons' subjective evaluations of the Break-30 and Break-60 conditions; however, the data suggest that Break-60 is preferable to the Break-30 condition.ConclusionsThis study provides evidence supporting the OR-Stretch Web-App as a potential surgical ergonomic intervention. However, enhancing the Web-App's user-friendliness and developing strategies to synchronize microbreaks with appropriate times during surgeries, to avoid disrupting the surgical workflow, are critical areas for future studies.",

However, data on their prevalence and associated factors in Turkey are limited to a few studies.ObjectiveTo investigate the prevalence of SRMSs and associated psychosocial factors among Turkish preschool teachers.MethodsThis cross-sectional study included 304 preschool teachers in Turkey. The Expanded Nordic Musculoskeletal Questionnaire was used to determine the prevalence of SRMSs in the previous 4 weeks (SRMSs-4w) and the previous 12 months (SRMSs-12m). Depression levels were assessed using the Beck Depression Inventory (BDI), quality of life was assessed using the Short Form-36 scale (SF-36), physical activity was assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).ResultsThe prevalence of SRMSs-12m and SRMSs-4w among Turkish preschool teachers was 57.2% and 54.9%, respectively. SRMSs-12m and SRMSs-4w were most commonly reported in the neck (35.5% and 34.9%), lower back (34.9% and 32.2%), shoulders (30.3% and 26.6%), and upper back (25.7% and 20.7%). BDI, SF-36 (energy/fatigue, pain, general health), PSQI, and IPAQ-SF were independently associated with 4-week SRMSs, while BDI, SF-36 (pain, general health), and PSQI were independently associated with 12-month SRMSs (p\u2009<\u20090.05).ConclusionsThe results showed a high prevalence of SRMSs among Turkish preschool teachers. SRMS prevalence was highest in the neck, lower back and shoulder regions. Furthermore, this study demonstrated associations between depression levels, quality of life, sleep quality, physical activity level, and SRMSs in preschool teachers.",

We hypothesized that both physical and psychosocial factors would be associated with pain, with an interaction between pain intensity and pain interference. A cross-sectional study was conducted among osteosarcoma survivors aged 18-39 years who had completed treatment at least 2 years earlier. Self-administered questionnaires assessed pain intensity and interference, physical function, fatigue, sleep disturbance, anxiety, depression, and perceived social support. Multiple regression analyses were performed to identify factors associated with pain outcomes. Semistructured interviews were also conducted to provide supplementary insights into pain characteristics and contextualize the quantitative findings. Among 64 participants, 65.6% reported pain or pain interference during the preceding 7 days. Pain intensity was significantly associated with poorer physical function, older age at diagnosis, and lower perceived social support, whereas pain interference was primarily associated with greater fatigue severity. Pain intensity and pain interference were strongly correlated. Qualitative analysis identified four pain characteristics prosthesis-related pain, phantom limb pain, secondary pain, and weather-related pain. Interviews further illustrated how physical limitations, fatigue, and social support shaped pain experiences. Pain among long-term osteosarcoma survivors is influenced by multiple biopsychosocial factors. Although average pain severity was relatively mild, substantial interindividual variability was observed. Comprehensive survivorship care should address physical function, fatigue management, and social support to optimize long-term pain management and self-care among AYA osteosarcoma survivors.",

This meta-analysis aimed to estimate the pooled prevalence of STS and identify potential moderating factors among nurses. From the inception of each target database to April 2026, a comprehensive search was performed across PubMed, Web of Science, Scopus, Embase, Cochrane Library, CINAHL, and PsycINFO. We calculated the pooled prevalence of STS using a random-effects model and assessed heterogeneity using the I2 statistic. Subgroup analyses and meta-regression were conducted to explore potential sources of heterogeneity. A total of 28 studies comprising 7,090 nurses were included. The pooled prevalence of STS in nurses was 57.3% (95% CI: 49.7-64.9%). STS prevalence was significantly associated with mean age (\u03b2 = -0.064, p = 0.023), work experience (\u03b2 = -0.080, p = 0.040), publication year (during COVID-19: \u03b2 = 0.979, p = 0.024; after COVID-19: \u03b2 = 0.848, p = 0.030), and geographic region (North America: \u03b2 = -0.881, p = 0.019; Europe: \u03b2 = -1.031, p = 0.005). Our findings indicated that STS was very prevalent in nurses, and the prevalence is moderated by mean age, work experience, publication year, and geographic region. Regular STS assessments and multi-level support systems, such as early warning, peer support, and mental health training, are recommended to reduce STS risk and enhance the wellbeing of nurses.",

However, the impacts of fermented soymilk on exercise-induced fatigue and its basic mechanisms remain unclear. Here, mice were gavaged fermented soymilk (FM), unfermented soymilk (BM), or normal saline (Control) for 30 days, followed by an exhaustive swimming test. Fatigue-related biochemical parameters, antioxidant indices, gut microbiota composition, fecal short-chain fatty acids (SCFAs), and KEGG functional pathways were analyzed. FM significantly extended exhaustive swimming time compared with the Control and BM groups. It reduced serum LDH and BUN levels, increased glycogen storage, and improved antioxidant capacity, as indicated by elevated CAT activity and reduced MDA levels. FM markedly reshaped the gut microbiota by enriching SCFA-producing genera, including Blautia, Faecalibacterium, Dysosmobacter, Roseburia, and Lachnoclostridium, while reducing opportunistic pathogens. It enhanced carbohydrate and amino acid metabolism, as well as microbial interaction pathways, thereby promoting the synthesis of acetate and butyrate. These findings suggest that FM improves exercise performance and alleviates fatigue by enhancing energy metabolism, reducing oxidative stress, and modulating gut microbiota and its metabolic functions.",

A fully remote, multicomponent intervention that combines ketogenic metabolic therapy (KMT) with behavioral interventions targets several proposed biological mechanisms underlying these conditions. This study aimed to characterize patient-reported experiences with a fully remote intervention that integrated KMT and thiamine supplementation with behavioral strategies, including circadian entrainment and mindfulness-based resilience coaching. In this cross-sectional study, quantitative data were collected via online REDCap surveys. Feasibility and acceptability benchmarks included perceived treatment suitability, relevance, safety, and reported treatment adherence. Optimization items evaluated preferred program duration, dosing, and structure, as well as components that respondents identified as most important for future refinement. Among an international sample (n=41), all feasibility and acceptability benchmarks were met: 96% reported the intervention was helpful, 96% recommended it, and 75% felt \"a lot better\" after completion. Respondents provided patient-centered perspectives to optimize the intervention. Incorporating patient perspectives is essential for guiding the development of safe, acceptable, and effective treatment strategies for infection-associated chronic illness, including Long COVID. Strong indicators of feasibility, acceptability, and perceived benefits support the rationale for larger controlled trials to investigate clinical efficacy and the underlying mechanistic pathways of multicomponent metabolic interventions.",

Identifying the potential clinical features that distinguish between these two disorders is essential for optimizing personalized management strategies for individuals with depression. In this study, we employed machine learning to develop a classification model to distinguish between BD and UD based on demographic and clinical features. Patients with either BD or UD were included in this study. Three machine learning classifiers, including logistic regression (LR), random forest (RF), and support vector machine (SVM) were developed and compared using a dual evaluation strategy: (i) nested stratified cross-validation (5-fold outer, 3-fold inner) for unbiased model comparison; and (ii) an independent stratified hold-out split for final validation. In the latter phase, hyperparameters were optimized on the training set via grid search, with performance reported on the test set using bootstrapped 95% confidence intervals. Shapley Additive Explanations (SHAP) analysis was applied to the optimal model to elucidate feature importance. A total of 449 patients (239 UD and 210 BD) were included. All three models achieved a consistent area under the receiver operating characteristic curve (ROC-AUC) of approximately 0.78, indicating moderate discriminative capacity, with the RF model demonstrating a more balanced error distribution. The top six predictive features were: family history, age, sleep disturbance (Patient Health Questionnaire-9 [PHQ9] item 3), fatigue (PHQ9 item 4), use of sleep medication (Pittsburgh Sleep Quality Index [PSQI] item 6), and suicidal ideation (PHQ9 item 9). The SHAP analysis suggested that younger age, \"uncertain/unknown\" family history, and the use of sleep medication tended to push predictions toward BD, whereas suicidal ideation, sleep disturbance, and fatigue tended to push predictions toward UD. Our machine learning approach identified key predictors-including age, family history, and sleep-related symptoms-to differentiate UD from BD in adolescent and young adult patients. Although achieving moderate accuracy, the model may serve as a supportive screening tool to enhance clinical decision-making.",

In this retrospective study, adult subjects who received additive composite restorations in maxillary anterior teeth after an orthodontic treatment were recruited. Study group consisted of patients who reported fracture of the additive composite restorations, whereas controls were recruited among the patients who reported success, according to the modified United States Public Health Service (USPHS) criteria. A bruxism evaluation was performed according to the Standardized Tool for the Assessment of Bruxism (STAB). A Scanning Electron Microscopy evaluation was conducted to obtain a fractographic analysis. A total of 40 restorations from 20 patients (8 males and 12 females, mean aged 25.67\u2009\u00b1\u20094.77 years) were evaluated. The following electromyographic variables resulted to be significantly different between groups: PC (p-value\u2009=\u20090.003), TC (p-value\u2009=\u20090.003), MC (p-value\u2009=\u20090.002), and TMC (p-value\u2009=\u20090.000). The fractographic analysis revealed that the fractures originated at the site of traumatic contact with the antagonist tooth. At follow-up, patients with fractured anterior restorations showed significantly higher masseter muscle activity, evaluated in terms of phasic contractions, tonic contractions, mixed contractions, and total masseter contractions using a portable sEMG portable device. The fractographic analysis findings may be considered compatible with repetitive mechanical fatigue. The small sample size did not allow to draw robust conclusions. Future studies are needed on larger samples trying to identify the possible relationship between bruxism and anterior restorations fracture.",

Four F33-34 athletes (1 national and 3 international levels) each performed 27 maximum-effort throws across nine pole configurations (3 pole positions\u2009\u00d7\u20093 grip heights) in a fully crossed within-subject design. Upper-body joint powers and pole forces were calculated using three-dimensional inverse dynamics and an instrumented throwing pole. Linear mixed models with random intercepts for athlete were used to assess the effects of pole position and grip height on 13 kinetic variables, with Benjamini-Hochberg false discovery rate correction. Within-athlete performance associations were tested for variables with significant pole configuration effects. A post-protocol fatigue check (three additional throws at each athlete's normal configuration) confirmed no significant performance decrement (d\u2009=\u20090.24). Pole position significantly affected seven of thirteen kinetic variables (all q\u2009<\u20090.05), including trunk axial rotation power (d\u2009=\u20091.15), throwing-arm shoulder power, and pole forces (posterior pole force d\u2009=\u20092.67). No grip height main effects or interactions survived correction. Despite these substantial kinetic changes, throw distance was not significantly affected by any pole configuration (marginal R2\u2009=\u20090.005). Of the seven significant variables, only mean lateral pole force was associated with within-athlete throw distance (\u03b2\u2009=\u2009-0.043\u2005m/N, q\u2009=\u20090.005), with a more laterally directed force linked to greater distance. Pole position is the primary equipment variable influencing kinetic strategy in seated shot put, while athletes maintain comparable throw distances through compensatory movement strategies. Mean lateral pole force is the sole kinetic variable that is both sensitive to pole position and predictive of performance, providing preliminary evidence that lateral pole force may be a useful candidate variable for individualised pole position selection, although the practical magnitude (within-athlete \u0394R2\u2009=\u20090.012) is modest. Pole configuration can be leveraged as a targeted training tool to modulate joint loading without compromising competitive performance.",

However, diagnosis can be particularly challenging in resource-limited settings where advanced tests are not readily available. Misclassification may result in non-selective chemotherapy exposure and increased toxicity. Reporting such cases is important to highlight diagnostic challenges in resource-limited countries. A 51-year-old male presented with abdominal discomfort, weight loss, and fatigue. Examination revealed splenomegaly. Initial evaluation suggested lymphoplasmacytic lymphoma, and the patient received multi-agent chemotherapy (R-CHOP), which was complicated by severe cytopenias. Splenectomy was performed, yielding a spleen weighing 2216\u00a0g. Histopathology and immunophenotyping confirmed hairy cell leukemia. Molecular testing for BRAF V600E (the gold standard for diagnosis) was unavailable due to financial and infrastructural restrictions. Treatment was switched to single-agent cladribine, resulting in marked clinical improvement and a significant reduction in chemotherapy adverse effects. Follow-up imaging and blood work revealed that the patient was in complete remission. In our case, we emphasize the diagnostic challenges of HCL in low-resource environments and clarify how the empirical administration of R-CHOP chemotherapy led to unnecessary toxicity and suboptimal outcomes. Splenectomy played a crucial diagnostic role when bone marrow tests were directional but not conclusive. We provide an extensive review of differential diagnoses, immunophenotypic hallmarks, what lies beyond the BRAF V600E mutation, and therapeutic approaches. Early recognition of HCL is crucial to avoid delayed optimal therapy and to enhance patient outcomes. This case emphasizes the critical role of morphology and immunophenotyping in confirming HCL, especially in resource-limited countries.",

This systematic review aimed to investigate the efficacy and tolerability of virotherapy treatment for recurrent and progressive glioblastoma patients. We also examined recent progress in preclinical and clinical trials, and future perspectives. We developed a search strategy using Medical Subject Headings (MeSH) terms and keywords. Inclusion criteria were English language published and ongoing clinical trials that involved patients undergoing virotherapy for glioblastoma. We searched through PubMed, Embase, Ovid, Scopus, Cochrane databases and https://Clinicaltrials.gov from inception until May 9th, 2025. Two independent reviewers screened records, extracted data, and assessed risk of bias (ROB2). No meta-analysis was performed due to heterogeneity. PROSPERO CRD420250636791. Of 975 records screened, 43 studies (24 published, 19 ongoing) enrolled 462 virotherapy patients. Most common adverse events: headache (n=145), fatigue (n=83) and fever (n=78). Risk of bias was moderate to serious in most studies. We encountered several limitations, including high heterogeneity, reporting inconsistencies, and small sample sizes. Most patients experienced disease stabilization. However, objective response and complete remission occurred infrequently. A small proportion of patients achieved long-term survival, suggesting that virotherapy could be effective in specific subgroups. While oncolytic virus therapy is generally tolerated, neurotoxicity remains the most significant risk. Adverse effects were mostly Grade 1-2. Some trials (notably with HSV-1 or NDV) had severe events. Symptoms were often transient and manageable but need closely monitoring. However, the observed heterogeneity, limited data standardisation, and lack of randomized controlled trials, besides tumor heterogeneity, antiviral immunity and immunosuppressive microenvironment, necessitate further research to identify predictive biomarkers and optimize therapeutic protocols. We also suggest further trials on novel delivery methods, such as the nanoparticles, to enhance blood-brain barrier (BBB) penetration.",

Existing vision-based driver monitoring systems are constrained by fixed temporal analysis windows and binary classifiers that neither quantify prediction uncertainty nor adapt to the heterogeneity of real-world fatigue dynamics, resulting in elevated false alarm rates and poor cross-domain generalization. This study introduces a confidence-driven adaptive time window (CDATW) framework: a closed-loop neuro-computational pipeline that couples a lightweight MobileNetV3-CBAM-BiLSTM spatial-temporal encoder with a Monte Carlo Dropout uncertainty estimator to produce simultaneous fatigue probability and epistemic confidence outputs at each inference step. The confidence signal governs a window controller that contracts observation periods to 5-10\u202fs under high certainty (confidence >0.85) for rapid warning, and extends them to 20-30\u202fs under low certainty (confidence <0.60) to suppress spurious alarms-instantiating the feedback-driven adaptive sensing principle central to neurorobotic perception. The framework was validated on four heterogeneous public datasets (NTHU-DDD, YawDD, UTA-RLDD, and DROZY) under single-dataset, cross-dataset transfer, and mixed-dataset training protocols. Single-dataset accuracy ranged from 88.6 to 91.8% with AUC of 0.92-0.95, while the adaptive mechanism reduced false alarm rates by 35.2% relative to fixed 15-s baselines. The architecture sustains 38-45 FPS on an NVIDIA Jetson Xavier NX automotive embedded platform, and confidence calibration achieves an Expected Calibration Error of 0.078, with high-confidence predictions (>0.9) attaining 95.6% accuracy. These results demonstrate that uncertainty-aware adaptive temporal reasoning embedded in a deployable neurorobotic architecture constitutes a computationally efficient and practically viable strategy for driver state monitoring in L2-3 autonomous vehicles, with broader implications for closed-loop perception in safety-critical human-machine systems.",

By using the capability, opportunity, motivation-behaviour (COM-B) framework, patient determinants influencing self-care can be explained. The aim was to describe patients' experienced facilitators of and barriers to self-care in surgical fast-track programmes related to capability, opportunity and motivation. A qualitative design study with semi-structured interviews was conducted among 27 general and orthopaedic surgery patients at three Swedish hospitals. Data were analysed deductively using the COM-B framework. The patients' self-care experiences were explained by capability, opportunity and motivation and the dynamic interaction between these factors. A key analytical finding was the pivotal role of family and friends, whose emotional and practical support strengthened patients' capability and motivation. Facilitators for behaviour change included prior surgical experience, clear information, physical ability, social and professional support, optimism and realistic goals. Barriers included cognitive and physical limitations, pain, fatigue and emotional distress. Findings highlight family involvement as an underused resource and support policy development of person centred pre- and postoperative self-care strategies. This study advances nursing theory by applying the COM-B model to illuminate interdependent behavioural processes in surgical self-care; themes could occasionally overlap.",

Patients with acquired communication impairments, such as post-stroke aphasia, are at increased risk for misdiagnosis, delayed care, and suboptimal treatment. We aim to better understand the unique needs of psychiatric patients with communication difficulties, common pitfalls in their care, and ways to improve clinical assessment, diagnosis, and treatment of their mental health conditions. We present the case of a 49-year-old woman with a history of major depressive disorder, generalized anxiety disorder, post-traumatic stress disorder, functional neurological symptom disorder, and a left middle cerebral artery ischemic stroke resulting in non-fluent aphasia. She was admitted to an inpatient psychiatric unit for suicidal ideation in the context of significant post-stroke functional decline. Her hospitalization was complicated by limited verbal communication and reliance on nonverbal modalities, cognitive fatigue related to communicating, persistent depression symptoms, as well as fluctuating reports of perceptual disturbances. Communication barriers significantly impacted assessment of mood, suicidality, and perceptual symptoms, contributing to diagnostic uncertainty and complex medical decision-making. This case highlights how expressive aphasia can obscure psychiatric assessment, increase reliance on interpretation by clinicians and caregivers, and contribute to potential misunderstanding of symptoms. It also underscores the importance of multimodal communication strategies and interdisciplinary collaboration. Psychiatric patients with communication impairments require tailored assessment approaches to reduce diagnostic error, gain greater understanding of the patient's clinical presentation, and improve overall patient care. Increased awareness and structured communication strategies may mitigate disparities in this vulnerable population.",

However, practical applications are often limited by several material bottlenecks: mechanical fatigue and conductivity loss under cyclic stress, the mismatch between degradation rate and functional lifespan, and the trade-off between sensitivity and biocompatibility. To address these challenges, artificial intelligence (AI) has been applied to accelerate structural optimization and property prediction through molecular network engineering and inverse design. Meanwhile, during the collection of coupled mechanical and biochemical signals, these interfaces usually suffer from high background noise, data variability, and baseline drift. Machine learning and deep learning can process these complex datasets through noise filtering, automated feature extraction, and pattern recognition, enabling continuous monitoring and adaptive health management.

Wearable assistive devices such as exoskeletons have been proposed as ergonomic solutions; however, evidence supporting their effectiveness in laparoscopic surgery remains limited. This study evaluated the feasibility and ergonomic impact of a passive upper-limb exoskeleton during laparoscopic procedures. This prospective crossover study used 28\u00a0porcine models. Twenty surgeons with varying laparoscopic experience each performed two laparoscopic intracorporeal gastrointestinal anastomoses, with and without a passive upper-limb exoskeleton. Surgeons were randomly assigned to begin either with the exoskeleton or without it. The primary outcome was total workload assessed using the NASA Task Load Index\u00a0(NASA-TLX), calculated as the mean of the six domains. Secondary outcomes included individual NASA-TLX domain scores and anastomosis time. Subgroup analyses were also performed according to laparoscopic experience (beginner, intermediate, expert) and anastomosis type (stapled vs. handsewn). No significant difference was observed between the exoskeleton and non-exoskeleton conditions for the primary outcome, the mean total NASA-TLX score. Among the secondary outcomes, the NASA-TLX domains Physical Demand and Effort were significantly lower with the exoskeleton than without it (72.5 [48.8-81.3] vs. 45.0 [25.0-67.5], p\u2009=\u20090.026; 65.0 [40.0-76.3] vs. 37.5 [30.0-70.0], p\u2009=\u20090.025). No significant differences were observed in the other NASA-TLX domains or in anastomosis time. In subgroup analyses, workload was significantly lower with the exoskeleton among expert surgeons (p\u2009=\u20090.036) and during hand-sewn anastomosis (p\u2009=\u20090.009). The exoskeleton did not significantly reduce overall workload. However, it decreased the NASA-TLX domains Physical Demand and Effort during laparoscopic procedures without compromising procedural performance. The reduction in workload appeared more pronounced among expert surgeons and during hand-sewn anastomosis.",
        "42418093": "ID: 42418093\nTitle: Comparative analysis of fatigue and mental health in sexual and gender minority cancer survivors.\nAbstract: This study aims to compare self-reported fatigue and mental health in sexual and gender minority (SGM) cancer survivors and cisgender-heterosexual cancer survivors. Using data from the National Institutes of Health's All of Us Research Program, survey responses from 36,684 respondents with a history of cancer were analyzed. Information collected from respondents included sexual orientation, gender, race, ethnicity, age at first cancer, history of anxiety or depression, and history of fatigue-related diagnoses. Outcomes included surveys assessing fatigue and mental health. SGM individuals were compared with majority groups using multivariable logistic regression. SGM survivors represented 6.6% of the sample. SGM survivors had increased odds of high fatigue than cisgender-heterosexual survivors (OR\u2009=\u20091.33, 95% CI[1.17, 1.51], p\u2009<\u2009.001). SGM survivors also experienced higher odds of self-reported poor mental health when compared with cisgender-heterosexual survivors (OR\u2009=\u20091.85, 95% CI [1.64, 2.03], p\u2009<\u2009.001). After controlling for anxiety, depression, and fatigue, SGM cancer survivors had higher odds of self-rated poor or fair mental health compared to cisgender-heterosexual cancer survivors. Fatigue and mental health are worse among SGM cancer survivors compared to cisgender-heterosexual survivors. Future interventional studies are needed to mitigate the unique fatigue and mental health needs of this population. Given the higher burden of fatigue among SGM cancer survivors, cancer care providers should screen for and address fatigue and mental health needs of SGM individuals impacted by cancer before, during, and after treatment to minimize the impact on their daily life. Outcomes for SGM survivors could be improved by routine sexual orientation and gender identity data collection in oncology settings and cancer databases, by education for SGM-serving primary care clinicians outside of cancer care settings on the care needs of survivors, and by piloting SGM-tailored interventions to address fatigue.",
        "42418108": "ID: 42418108\nTitle: Low work ability and high disability burden in Cushing's syndrome: a multicenter cohort study.\nAbstract: The socio-occupational burden of Cushing's syndrome (CS) remains underrecognised. In clinical practice, surgically treated patients are often considered recovered, potentially overlooking persistent impairment. To evaluate work ability, social and employment status in newly diagnosed and remitted CS. National observational study with two arms: a monocentric prospective study of patients evaluated for suspected endogenous glucocorticoid excess (cohort 1), and a multicenter cross-sectional study of patients in remission from CS, comparing those with recovered versus persistent adrenal insufficiency (cohort 2). All participants underwent standardised assessments and completed validated questionnaires on socioeconomic status, work ability, and fatigue. In cohort 1, individuals with active CS (n\u2009=\u200928) and excluded CS (n\u2009=\u200956) had comparable comorbidities, education, and employment. However, work ability scores were lower in active CS (median 22.5 vs. 28.5, p\u2009=\u20090.008) and correlated inversely with biochemical cortisol excess. In multivariable analyses, active CS and depression were independently associated with lower work ability, whereas older age and depression were independently associated with fatigue severity. In cohort 2 (n\u2009=\u200989, 39 with recovered, 50 with persistent adrenal insufficiency), overall employment was 69%. Poor work ability was common (42% with recovered vs. 58% with persistent adrenal insufficiency) and weekly working hours were lower in those with persistent insufficiency (33\u00a0h vs. 39\u00a0h, p\u2009=\u20090.051). Overall, illness-related absences occurred in 76% during the preceding year, disability was recognised in 47%, and 15% received reduced earning capacity pensions. Fatigue correlated negatively with work ability (r = - 0.73, p\u2009<\u20090.0001). There is an unmet need for structured rehabilitation and reintegration in CS."
