Étude des aspects lésionnels de l’échinococcose hydatique chez l’Homme en Mauritanie: fertilité, histologie des kystes hydatiques et viabilité des protoscolex

Abstract

A lesional study on human hydatidosis (localization, fertility of cysts, protoscolex viability, and histological structure) focused on 63 human hydatid cysts from patients operated at CHN of Nouakchott was conducted during the period 1997-2007. The authors report the following results: the annual surgical incidence rate was in the order of 1.2% per 100,000 inhabitants. The lung was the primary localization of cyst (52%) followed by the liver (33%), spleen (4%), brain (3%), heart (2%), breasts (2%), kidney (2%), diaphragm (1%), and peritoneum (1%). The pulmonary cysts were larger and more fertile (76%) with protoscoleces also more viable (70%) compared with liver cysts (67-62%). The histology of hydatid cysts revealed in most cases a histological structure consistent with that described in the literature: thick cuticle, membrane proligeous, and capsules visible.

Viability predictive factors of the daughter vesicles in hepatic cystic echinococcosis

“…There is a little work on the viability of protoscoleces. The results vary from one series to another due to the non-standardization of the methodologies applied to the study of parameters [ 1 , 2 , 4 , 10 – 14 ]. These works are only interested in the study of echinococcal fluid from cysts in humans and animals.…”

“…Proper management of CE requires knowledge of certain aspects related to the survival of the parasitic agent, particularly protoscolex. In the literature, the study of the fertility of cysts and the viability of protoscoleces has always been performed on echinococcal fluid (EF) [ 1 , 2 ]. However, no study concerning the lesional aspects of daughter vesicles (DV) is available at present.…”
