[Schistosoma haematobium bilharziosis and urinary infections. Study of their relationship in 2 villages of Niger].
In order to assess the relation between urinary schistosomiasis and urinary tract infections (U.T.T.), a study of two villages in the surroundings of Niamey (Rep. of Niger) was undertaken. In the first village located near a rice plantation irrigation scheme, the global prevalence of S. haematobium infection was 77%. Boys between 5 to 14 years of age were all infected and their mean egg output was 500 eggs/10 ml of urine. In the second village, where water is supplied from wells, schistosomiasis was almost absent. Urinary tract infections were diagnosed upon the cytologic count of the urinary sediment and the urine culture. Comparison between S. haematobium infected and non-infected villages showed that the prevalence of U.T.I. was 3.8 times higher among the females of the infected village. This was also noticed for old men and especially for boys aged 5 to 14 (5.2% U.T.I.) for whom urinary infection is usually uncommon. However the mean blood pressure and the creatininemia showed no difference between the two populations. If schistosomiasis increases the risk of chronic pyelonephritis, that increase could not be accounted for with the measures of these two variables.
