Urinary leucine aminopeptidase in bilharziasis.

Abstract

Leucine aminopeptidase activity and total protein concentration was estimated in the fresh early morning sample of urine of twenty five normal adult subjects, twenty four cases with active urinary bilharziasis, eleven cases with active intestinal bilharziasis, ten cases with mixed bilharzial infection (urinary and intestinal), fourteen bilharzial cases with clinical hepatosplenomegaly of bilharzial etiology, thirteen bilharzial cases with clinical hepatosplenomegaly and ascites, and twelve cases with cancer bladder of bilharzial etiology. It was found that there is a significant increase in LAP activity in the urine of all groups of patients studied. Again this increase ran parallel to the course of the disease in bilharzial cases. Urine protein concentration was found to be increased significantly in all groups of bilharzial cases studied with the highest value in urine of patients with cancer bladder of bilharzial etiology. However no direct correlation was found between urinary LAP level and protein concentration either within the individual cases or within the different groups.
