[Diagnostic value of determining neutral alpha-glucosidase and N-acetyl-beta-D-hexosaminidase activity in the urine in kidney pathology].

: As shown in studies of 123 patients with various nephropathies, activities of alpha-glucosidase and N-acetyl-beta-D-hexosaminidase in urine of the patients correlated with severity and stages of these diseases; at the same time, simultaneous estimation of both enzymatic activities in urine was shown to be more informative in diagnostic of kidney impairments. Low values of correlation coefficient (r = 0.35 +/- 0.09) between daily excretion of protein and the activity of neutral alpha-glucosidase in urine showed that the enzyme activity did not depend on proteinuria and was independent test for kidney impairment. Estimation of alpha-glucosidase activity could be used for control of the therapy; the enzymatic activity in urine correlated distinctly with the clinico-laboratory patterns of the patients studied.
