Urinary excretion of glycosaminoglycans (GAGS) and sialic acid (SA), as well as the activity of two renal enzymes related to glycoprotein metabolism, N-acetyl-beta-D-glucosaminidase (NAG) and beta-galactosidase (GAL), and two others unrelated to glycosaminoglycans and glycoprotein metabolism, gamma-glutamyltranspeptidase (gamma-Gt) and angiotensin-I-converting enzyme (ACE), were evaluated in 40 insulin-dependent diabetic patients with normal range albuminuria, 21 patients with mesangial glomerulonephritis, and 30 control subjects. Diabetic and glomerulonephritic patients excreted a significantly higher amount of GAGS and SA, and showed greater NAG and GAL activities; gamma-Gt and ACE levels were within normal ranges. No correlation could be demonstrated between diabetes duration and GAGS, SA, NAG and GAL findings. Moreover, no correspondence between degree of metabolic control, as reflected by glycosylated hemoglobin (HbA1a-c) and GAGS, SA, NAG and GAL emerged.

The early renal function parameters (RFP), i.e. urinary alanine aminopeptidase (AAP), beta-galactosidase (beta GAL), N-acetyl-beta-D-glucosaminidase (NAG), retinol-binding protein (RBP), albumin (ALB), total protein (TP) and the conventional RFP plasma creatinine were assessed in 8 patients before and during treatment with the nephrotoxic antitumor agent cis-platin. Plasma creatinine increased during treatment with cis-platin. In all patients, acute tubular damage was revealed by early RFP. Albumin and total protein excretion patterns suggested alterations in glomerular function. The cumulative change in RBP excretion was related to plasma creatinine concentrations following cis-platin administration. The present study demonstrates that urinary RBP is a valuable parameter for the early assessment of cis-platin-induced nephrotoxicity.
