Résumé

BACKGROUND: Schistosomiasis is a major public health issue for migrants. This study aims to describe the clinical presentation and management of imported schistosomiasis in France. METHODS: We included all new cases of schistosomiasis in patients aged ≥18 years, defined by a positive specific Western blot and/or a positive parasitological analysis of urine, stool or biopsy, between January 1, 2016, and December 31, 2019, in 4 laboratories in Paris and Western France. RESULTS: Over the study period, 532 patients were included. Mean age was 37 years (18-91), and 461/532 (87 %) were men. Among 476/532 (89 %) patients born in an endemic area, 433 (91 %) were born in sub-Saharan Africa. Most of the patients (405/532, 76 %) had only a positive serology, and 127/532 (24 %) had ova on microscopic examination. Among 361/532 (68 %) who had at least one urine, stool or biopsy analysis, microscopic analysis was positive in 127 (35 %). Imaging showed lesions compatible with schistosomiasis in 88/164 (54 %) patients with clinical symptoms and 13/29 (45 %) patients without (p = 0.5). Patients who arrived in France less than one year before diagnosis were more likely to have clinical symptoms than those who arrived in France 1-5 years and >5 years prior to diagnosis (52 %, 41 % and 43 %, respectively, p = 0.03). Two-hundred and seventeen patients (40.8 %) were left untreated. CONCLUSION: Approximately 50 % of patients with imported chronic schistosomiasis have radiological abnormalities, whether they are symptomatic or not, and management is heterogeneous. Multidisciplinary international guidelines are requested to clarify the management of this neglected disease.
