Filter by:The objective of the study is to estimate the incidence of Jarisch-Herxheimer Reactions (JHR) during antibiotic treatment of human leptospirosis cases in New Caledonia. Participants are patients managed in one of the 5 centres participating in the study, in whom a clinical doctor suspected leptospirosis. The average number of leptospirosis cases in New Caledonia is 89 per year. Given the proportion of positive diagnostic tests (approximately 10%) 900 inclusions are planned for this study. Patients are included at the time of the consultation during which leptospirosis is suspected, before the initiation of their antibiotic therapy and independently of the clinical form they presented. Data (socio-demographic and health) and blood samples will be collected at 3 points in the study: at baseline, three hours and six hours after antibiotic treatment. This study will allow better management of patients with leptospirosis.
Abstract Background Tick-Borne Relapsing Fever (TBRF) is an acute febrile illness. In Israel, TBRF is caused by Borrelia persica and is transmitted by Ornithodoros tholozani ticks. We examined the safety and efficacy of a post exposure treatment policy to prevent TBRF. Methods In a double blind, placebo controlled trial 93 healthy volunteers with suspected tick exposure (51 with bite signs and 42 contacts) were randomly assigned to receive either Doxycycline (200 mg for the first day and 100mg/d for 4 days) or placebo, approximately 2 days after contact. Blood smears were examined for Borrelia at inclusion and during fever rise. Serology for Lyme disease cross- reactivity and PCR for Borrelia GlpQ gene were also performed. Cases of TBRF were defined as subjects having fever and a positive blood smear.
