Determination of urinary and serum beta-glucuronidase and alkaline phosphatase in various renal disease and kidney rejection transplanted patients.

Beta-glucuronidase (beta-Glu) and alkaline phosphatase (ALP) were evaluated in serum and urine in 50 subjects classified into five equal groups. Group I was control healthy subjects, while groups II, III, IV, and V were patients with nephritic syndrome, pyelonephritis, kidney rejection, and end-stage renal disease, respectively. Urinary beta-Glu was significantly elevated in all four groups; while serum enzyme showed no change. On the other hand, serum ALP showed a significant elevation in all abnormal groups. Accordingly, urinary beta-Glu and serum ALP could be used as diagnostic markers for various renal diseases.
