title: [Clinical significance of enzymuria in glomerulonephritis in children].
abstract: The authors presented the results of a study of enzymuria (cholinesterase, gamma-glutamine transferase, alkaline phosphatase, beta-galactosidase and lactate dehydrogenase with separate determination of N- and M-subunits) in 20 patients with a mixed form of glomerulonephritis (GN), 36 with the nephrotic form of GN and 13 patients with the hematuric form of GN. The clinical importance of the determination of enzymatic activity in the urine in GN of children lies in the recognition of the degree of damage of the glomerular filter as well as the nephrothelium. Basing on enzymuria pathophysiological syndromes found in various combinations in the above forms of GN were identified. Three degrees of damage of the permeability of the glomerular filter were defined for high molecular proteins. Differences in individual values of the activity of some enzymes gave rise to differential-diagnostic coefficients as well as differential-diagnostic tables which could be used for differential diagnosis between the GN mixed and nephrotic forms.
