[Study of anemia in giardiasis intestinalis in Tunisian preschool children]. / Etude de l'anemie au cours de la giardiase chez des enfants Tunisiens d'age prescolaire.

The present work is based upon a prospective in study done in a semi-urban area of suburbs of Tunis, from february to November 1997. A total of 302 children aged between 6 month to 5 years were enrolled in the survey. The study aimed at assessing the extention of parasitoses in preschool aged children. The relationship between the Giardiasis intestinalis and ferropenic anemia. The prevalence of anemia is 31.78% (n = 302). The parasitologic analysis has shown that 113 children out of 302 are infected; 37.41%. We observed an obvious predominance of Giardia Lamblia: 62% (n = 113) pathogenic protozoon. The rate of anemia parasited children is amounted to 19.78%. During the Giardiasis, anemia is present in 23.17% of the cases. The Polyparasitism concerns 16% of the infested children. This anemia could be caused by a global bad absorption syndrome or by a ferro-elective bad absorption. A proper sanitary education, a purification action and also a curative treatment of the beaners carriers will be the only guarantees to decrease its morbidity.
