Some urinary enzymes in bilharziasis.

Urinary alkaline phosphatase (ALP), acid phosphatase (ACP), aryl sulphatase (Ar. sulph.), beta-glucuronidase (beta-gluc.) and galactosidase were assayed in a group of Bilharzia haematobium patients and another group of healthy subjects (control group). The results for most of the determined enzymes revealed high activities as compared to the controls. The activity of acid phosphatase in male urine samples increased also, though not significantly. These elevated enzyme activities could be used to establish the diagnosis of schistosomiasis in patients whose urine contains no ova or when it is difficult to detect them. The results are discussed in the light of localization of each enzyme in the urinary tract as well as in other organs like the liver.
