Portage parasitaire digestif d'enfants adoptés

Abstract

Introduction: Patients et méthodes: Résultats: Discussion: Introduction: Intestinal parasitoses are very common infections in tropical areas. By contrast, they are rarely diagnosed in developed countries, and are mostly seen in specific populations. Patients and methods: This analytical observational study was longitudinally performed in a French university hospital (2007-2011). It dealt with the study of gastrointestinal carriage of parasites in internationally adopted children. A standard stool examination was therefore systematically undertaken for every new immigrant. Association with risk factors was made by uni- and multivariate analysis. Results: Overall, 69 stool samples were analyzed. The proportion of positive samples was 78 %. Protozoans, mainly Giardia duodenalis, were more prevalent than helminths. In univariate analysis, a subject's low weight and height were significantly associated with intestinal parasite carriage. Amoebae were more frequent in older children and in children from Haiti, as confirmed by the trend observed in the multivariate analysis. Flagellates were seen more often in African children. Infections with multiple parasite species were observed in half of the study population, and were inversely correlated to increasing age. Discussion: According to the results of this study, gastrointestinal parasites are still very frequent in stool samples from immigrant children. Since they are easy to transmit, the majority of infections were protozoan. The best antiparasitic strategy lies in: (a) the routine screening of stool from any immigrant child coming from endemic areas and (b) the use of antiparasitic treatment.
