[Kidney lesions in non-insulin dependent diabetes mellitus].

Because little is known about disordered metabolism of uric acid as a pathogenetic mechanism of renal damage in non-insulin-dependent diabetes mellitus (NIDDM) it was studied in 75 NIDDM and 48 IDDM patients. Clinical examination of the patients included evaluation of purin metabolism according to serum uric acid, diurnal urine excretion, uric acid clearance. Hyperuricemia occurred more frequently in NIDDM. Positive correlation was observed between hyperuricosuria and the severity of diabetic nephropathy which was more pronounced in IDDM.
