title: [Circumstances for diagnosis and treatment of intestinal parasitosis in France].
abstract: In a compatible context, hypereosinophilia is suggestive of helminthosis. When the count is higher than 1000/mm(3), a primo-invasion syndroma may be considered, especially if allergic signs are present. Below that level, the helminthosis is probably at the adult stage (chronic phase). In a chronic diarrhoea occurring after a journey abroad, "emerging" protozoa (crypto-microsporidia, Isospora, Cyclospora…) are possibly in cause. A presumptive treatment may be considered. A systematic screening for schistosomiasis (serology and stool examination) is recommended in travellers exposed to the risk (contacts with fresh water) and in immigrant from endemic areas (mainly sub-Saharan Africa) since the disease may be asymptomatic. In young children living communally, two courses at 15 days interval against giardiosis or enterobiasis are recommended for both infected and contact persons. In order to avoid disseminated strongyloidiasis, severe and possibly lethal, a systematic course of ivermectine is strongly recommended before any immunosuppressive treatment in patients having stayed in tropical areas even for a short period and even decades ago. Albendazole became the reference drug for intestinal helminthiasis with in addition a good efficacy on giardiasis. Since some intestinal parasites are not pathogenic, a treatment is not necessarily required when a parasite is found in a stool examination.
