OBJECTIVE: Animal studies suggest that hyperlipidemia may play a direct role in glomerular damage. In patients with non-insulin-dependent diabetes mellitus (NIDDM), dyslipidemia occurs early in the course of nephropathy and may be involved in the progression of renal disease. CASES: We report on two young NIDDM patients with marked hyperlipidemia and proteinuria, in whom renal biopsy demonstrated nondiabetic glomerulopathy. In both cases, the decrease in blood lipid levels was associated with a major decrease in proteinuria. Episodes of hyperlipidemia were associated with a resumption of heavy proteinuria in one patient with serum triglyceride levels and proteinuria being closely correlated. CONCLUSIONS: These two cases suggest that hyperlipidemia has an important role in the pathogenesis of glomerular disease.
