Filter by:The aim of the study is to investigate the applicability and performance of 64Cu-DOTATATE PET/CT/MR for diagnosis in patients with Lyme neuroborreliosis (LNB) . In this prospective, observational cohort study with 64Cu-DOTATATE, we wish to include a total of 50 patients clinically suspected of LNB. We will investigate the diagnostic value of 64Cu-DOTATATE-PET comparing clinically suspected and CSF verified LNB patients with clinically suspected patients without CSF verification. We hypothesize that the information obtained from 64Cu-DOTATATE PET/CT/MRI can improve the diagnostics of LNB. We also hypothesize that 64Cu-DOTATATE PET/CT/MRI will be able to contribute to the follow-up of patients by adding prognostic information and the risk of persistent symptoms. The application of 64Cu-DOTATATE PET/CT/MRI in the diagnostic work-up of LNB would thus expectedly lead to a more precise diagnosis and risk assessment.
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 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.
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.
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.
A cross-sectional descriptive survey of the BOLD for individuals after having been ill with COVID-19 or have taken the COVID-19 vaccine will be compared with that of individuals who have neither been ill with COVID-19 nor taken the COVID-19 vaccine. Individuals who have both been ill and taken the COVID-19 vaccine will be compared to identify any additive risk factors.
Background: Each year, the number of cases of tick-borne diseases increases. The deer tick (Ixodes scapularis) is the vector of at least 7 pathogens that cause human diseases, including Lyme disease. Researchers want to learn more to help them develop vaccines against ticks in the future. Objective: To learn how people s bodies, particularly the skin, respond to tick bites. Eligibility: Healthy adults aged 18 years and older who have no known history of a tick-borne disease or tick bite exposure. Design: Participants will be screened with a medical history, physical exam, and blood tests. Participants will have 2 skin punch biopsies of healthy skin. For this, a sharp instrument will be used to remove a round plug of skin about the size of a pencil eraser. Participants will then have 10 clean laboratory-bred ticks placed at 2 different sites on their skin (20 ticks total). The ticks will be removed from the first site 1 day after placement and from the second site 2-4 days after placement. Participants will complete symptom diary cards. They will answer questions about itching at the tick feeding sites. They will give blood samples. Photos will be taken of the tick feeding sites. Skin punch biopsies will be collected at the sites of the tick bites. Participants will repeat the tick feeding procedures 2 times, each 2-8 weeks apart. For the 2nd and 3rd procedures, 10 clean laboratory-bred ticks will be placed at 1 site. The ticks will be removed 2-3 days after tick placement. They will have telephone follow-up visits after each procedure. After the final tick removal, participants will have follow-up visits in 4-6 weeks and again in 3 months. They will give blood samples and discuss how they are feeling. Participation will last about 5-7 months.
Non-interventional study evaluating stool and blood samples collected from individuals previously treated with Lyme disease versus healthy volunteers
Lyme borreliosis is a bacterial multisystemic infection transmitted by an Ixodes tick. It affects the skin, the joint and the brain. At the early phase, the diagnosis is clinical, relying on the presence of an erythema migrans at the site of the tick bite. The diagnosis of disseminated infections, more difficult to assess, mainly relies on indirect diagnosis test, i.e. serology. This study will evaluate a new direct diagnosis method based on proteomics, which aims to demonstrate proteins of live bacteria in the skin and the synovial or cerebrospinal fluids in a direct manner.
