Analysis of urinary glycosaminoglycan excretion in kidney diseases demonstrates potential biomarkers for renal pathology.

Key Points

The study aims to evaluate glycosaminoglycan (GAG) excretion in renal pathology, focusing on patients with mesangial and membranous glomerulonephritis.
Analyzed urinary GAG excretion in 20 patients with IgAGN, 18 patients with MGN, and 18 healthy controls.
Isolated GAG from urine using ion-exchange chromatography.
Determined GAG composition by cellulose acetate electrophoresis and densitometric scanning.
Total GAG levels were significantly higher in patients with MGN compared to controls and IgAGN patients.
Low sulfated chondroitin sulfate proteoglycan was observed in all patients, but controls had higher levels.
A significant reduction in chondroitin sulfate was found in both IgAGN and MGN patients.
