Emerging research ch underscores thate relationship between dyslipidemia and diabetic complicicats extends beyond atherosclerosis. Lipid deposition with ith kidney, specilarly in glomerular cells and tubulaar epibhelial cells, initiates a cascade of cellular stres responses that directly contribute to proteinuria and declining renal function.

Proteinuria as a Sentinel Marker of Perl Injury

Proteinuria, definiuje as urinary albumin exceediing 30 mg per day, is the arliest clinically decognitable sign of diabetic nefropathy. The transition from normoalbuminuria to microalbuminuria and eventually to macroalbuminuria correlates with progressive structural damage to the glomerular filtration congreer.
