Diabetic nephropathy: Recent insights into the pathophysiology and the progression of diabetic nephropathy

Diabetic nephropathy: Recent insights into the pathophysiology and the progression of diabetic nephropathy. Diabetes has become the single most frequent comorbid condition in patients admitted for renal replacement therapy. This is the result of a greater prevalence of type 2 diabetes and better survival of diabetic patients. Progress has been made in pinpointing the predisposition to diabetes on metabolic abnormalities of muscle mitochondrial metabolism, but the long sought genes predisposing to diabetes and to diabetic nephropathy have not yet been identified. Of great concern are experimental studies documenting that maternal hyperglycemia causes nephron underdosing in the offspring.Relevant to pathogenesis and treatment of diabetic nephropathy are, among others, recent insights that hyperglycemia sensitizes target organs to blood pressure–induced damage, and that local renin-angiotensin systems play an important role in genesis and progression of diabetic nephropathy
