[Urine fibrinolytic activity as an indicator of kidney damage in uric acid metabolic imbalance].
OBJECTIVE
To determine functional fibrinolytic activity of the urine in patients with different forms of purine metabolism disorder.


METHODS
Uricemia, 24-h uricosuria, serum creatinine, GFR, maximal urinary specific gravity, urokinase activity in the urine, total fibrinolytic activity of the urine (TFAU), activity of plasminogen activator inhibitor (PAI) in blood were studied in 33 patients with genetically determined purine metabolism disorders.


RESULTS
Patients with purine metabolism disorders vs controls had decreased TFAU and urokinase activity. There was no significant difference between the study and control groups in the levels of PAI in blood. No statistically significant difference was found between the patients with hyperuricemia and patients with hyperuricosuria in the levels of TFAU and urokinase activity, while the group with hyperuricemia was characterized by a decreased maximal specific urinary gravity.


CONCLUSIONS
A decrease in TFAU and urokinase activity in patients with purine metabolism disorder was observed in the isolated hyperuricosuric stage of urite renal damage.
