Filter by:The investigators propose a single center, prospective observational study in children with Lyme disease (LD), the Borrelia B-cell diagnostics (BRILLIANT) study, to assess the immune response against Borrelia burgdorferi (Bb) with the following main objectives: 1. Development of Bb-specific ASC ELISpot as a new test method for diagnosis of early LD. There is an urgent unmet clinical need for a better diagnostic tool for early LD, as the current standard two-tier testing has low sensitivity in recently infected patients and may show false positive results in recovered patients due to long-term persistence of antibodies against Bb. The measurement of Bb-specific ASC with the ELISpot assay my has the potential to overcome these issues and to improve diagnosis in early LD. 2. Extensive analysis of the immune response in LD. The immune response in LD is not well understood. Large-scale studies assessing the detailed immune cell subsets/phenotypes present in blood, CSF, or synovial fluid of LD patients with respective manifestations are lacking. 3. Isolation and characterization of causative Bb species. Existing literature suggests that Bb genospecies and/or genotypes may determine virulence and manifestations, but large-scale studies assessing Bb genospecies/genotypes in different manifestation of LD are lacking. 4. Collection of clinical data about symptoms, severity, routine laboratory and diagnostic test results, treatment, and outcome of LD. 5. Biobanking samples for analysis in the future. Project population Inclusion criteria: Children, 0-17 years of age, at University Children's Hospital Zurich: - LD differential diagnosis cohort: Patients presenting at the ED with differential diagnosis of LD according to the treating physician. - Control cohort: Previously healthy patients (HC) with routine blood investigations presenting at the ED or PID outpatient department Exclusion criteria: Primary or secondary immunodeficiency.
The purpose of this pilot study is to assess the feasibility of longitudinal neurodevelopmental evaluation of fetuses and infants exposed to Lyme disease in utero. Participants with Lyme disease or Post-Treatment Lyme Disease Syndrome (PTLDS) will be recruited during pregnancy. Pregnancies will be monitored and infant development will be assessed from birth until age 18 months.
The purpose of this study is to evaluate the safety and immunogenicity in parallel of heptavalent mRNA-1975 and monovalent mRNA-1982 against Lyme disease in healthy adult participants.
The aim of this study is to assess B. burgdorferi antibodies in children and adolescents in north-western Switzerland and neighbouring countries ("Triregio") treated at the University Children's Hospital Basel to define age-dependent B. burgdorferi seroprevalence rates.
This study is one of the first studies to investigate a non-antibiotic approach to the treatment of symptoms that persist after antibiotic treatment for Lyme disease (PTLS). Transcutaneous auricular vagus nerve stimulation (taVNS) offers the potential of being an effective and non-toxic approach to reduce the burden of multisystem symptoms in patients with PTLS. This study seeks to address an important goal: to assess the safety, feasibility, and tolerability of a new non-invasive, non-pharmacologic treatment for patients with symptoms that persist despite prior antibiotic treatment for Lyme disease.
the study is offered to adolescents aged 12 to 17 and their families suspected of or suffering from Lyme barilliosis. During inclusion, three interviews will be carried out for each family. This choice of the number of interviews per family seems the most appropriate to have a plurality of answers to the questions asked. Thus, these will have a duration of 30 min to 1 hour and will be carried out by an anthropologist. The first interview will be with the teenager. The second interview will then concern the parent(s). Finally, the last appointment will be with the teenager and his parents.
Lyme borreliosis, commonly known as Lyme disease, has been clinically described for more than a century, but has been officially recognized for 40 years, with the detection of the Borrelia bacterium by W. Burgdorfer, in ticks of the Ixodes ricinus complex, identified a few years before.
This study is to understand if the study vaccine (called VLA15) is safe in healthy children. We are looking for children who: - are healthy - are age 5 through 17 - have not been diagnosed with any form of Lyme disease in the past - have not received any vaccines for Lyme disease in the past Lyme disease happens most often in children of this age. The study vaccine may be used potentially to help prevent Lyme disease. The goal of this study is to get more information about the safety of the study vaccine in this age group. Participants will be in this study for about 2 years. During that time, they will receive VLA15 or placebo (sterile saltwater solution) by a "shot" in the arm. We will compare experience of children receiving VLA15 to those receiving the placebo. Participants will not know whether they get VLA15 or placebo. Everyone participating in this study will: - get the shots in a clinic or in a hospital office - receive a total of 4 shots - receive the first 3 shots within 6 months - receive the last shot about 1 year afterwards - need to come to the trial site for 6 planned visits; 4 of these are vaccination visits and 2 are follow-up visits. We will contact you by phone 1 time every year during the study to monitor your experience. You may have extra visits if you experience a severe reaction after a vaccine dose.
Neuroborreliosis (NBL) is diagnosed in 10-15% of patients with Lyme borreliosis. In Europe in adults, the main clinical manifestation is called "Bannwarth syndrome". This includes painful meningoradiculitis, sometimes accompanied by cranial nerve neuritis. Current European guidelines issued by the European Federation of Neurological Societies (EFNS) recommend the following triad for the diagnosis of "definite NBL": (i) Neurological symptoms suggestive of NBL without any other obvious cause; (ii) CSF pleocytosis; (iii) Intrathecal production of specific anti-Borreliella antibodies. CXCL13, C-X-C chemokine motif ligand 13, is a chemokine implicated in B cell chemotaxis. Extensive literature exists on the analysis of CXCL13i as a diagnostic marker for acute NBL. A recent meta-analysis from 2018, published by Rupprecht et al finds an overall sensitivity and specificity of 89% and 96% respectively, indicating satisfactory diagnostic value. In this study, the investigators wish to assess the place of this new marker in the diagnosis of neuroborreliosis before proposing it as a test carried out by the Borrelia CNR.
The main purpose of this clinical study is to evaluate a 6-valent OspA-based Lyme disease vaccine (VLA15) for prevention of Lyme disease within North America and Europe. Approximately 9,000 healthy participants 5 years and older will be recruited from areas with high levels of endemic Lyme disease to receive VLA15 or placebo (an inactive substance consisting of saltwater). Each participant will have about a 50% chance of receiving VLA15 and about a 50% chance of receiving placebo. A subset of participants will receive VLA15 from 3 different lots or placebo (1:1:1:3 ratio) to assess lot equivalence. Participants will receive a 3-dose primary vaccination series at about 0, 2, and 5 to 9 months and then receive a booster dose about 12 months later. Vaccination of participants will occur at a time of year such that the primary series is completed before the peak Lyme disease season followed by a booster dose just prior to the beginning of the second Lyme disease season. Comparison will be made between the Lyme disease cases of people receiving the study vaccine to those of the people who are not. This will help us determine if the study vaccine is safe and effective. If enrolled, participants will need to visit the research site at least 7 times during the study. There will also be at least 5 telephone contacts. It is expected that each participant will take part in this study for up to about 2 and a half years.
