[Urinary excretion of extracellular matrix proteins in insulin dependent diabetes mellitus].
The purpose of the study was to assess urinary excretion of extracellular matrix proteins and proteolytic enzymes in 12 subjects with IDDM with albuminuria, 12 subjects with IDDM without microalbuminuria and 10 normal healthy subjects. Urinary excretion of FN was significantly higher in subjects with IDDM and albuminuria as compared to patients with IDDM without microalbuminuria and healthy subjects (223.6 +/- 143.2 vs. 103.2 +/- 59.7 vs. 58.3 +/- 12.0 ng/mg creatinine, p < 0.01). Urinary level of type IV collagen was significantly elevated in subjects with IDDM and albuminuria as compared to IDDM without microalbuminuria and healthy subjects of cathepsin B was significantly higher in diabetic patients with albuminuria as compared to patients without microalbuminuria and healthy subjects (0.82 +/- 0.53 vs. 0.25 +/- 0.17 vs. 0.22 +/- 0.05 mlU/mg creatinine, p < 0.01). Urinary activity of plasmin was significantly elevated in diabetic patients with albuminuria as compared to subjects without microalbuminuria and healthy control (0.477 +/- 0.37 vs. 0.194 +/- 0.09 vs. 0.21 +/- 0.02 mlU/mg creatinine, p < 0.01). Our data indicate that increase in the urinary excretion of extracellular matrix proteins may be the useful tool for monitoring glomerular injury.
