title: Medical management of nephropathy in type I diabetes mellitus: current recommendations.
abstract: Diabetic nephropathy is the single most common cause of end-stage renal disease in the United States. Recently, several major therapeutic interventions have been developed and demonstrated to slow or halt the progression of renal failure in patients with diabetes and diabetic kidney disease. The Diabetes Control and Complications Trial demonstrated that microalbuminuria developed in fewer patients in the intensive blood sugar control group than in the conventional therapy group. Similarly, the risk of developing proteinuria was reduced by intensive blood sugar control. Multiple studies have demonstrated that in patients with insulin-dependent diabetes and proteinuria, lowering the systemic blood pressure slows the rate of decline in renal function and improves patients' survival. In the recently completed trial of ACE inhibition in diabetic nephropathy, ACE inhibitors were specifically shown to decrease dramatically the risk of doubling of serum creatinine or reaching a combined outcome of end-stage renal disease or death. In studies in small numbers of patients with insulin-dependent diabetes and established diabetic nephropathy, dietary protein restriction has also been demonstrated to slow the rate of decline of renal function. New potential interventions currently undergoing study include the use of aldose reductase inhibitors, the use of drugs that prevent the formation of advanced glycosylation end-products, and the use of angiotensin II receptor antagonists. Thus, several established benefits have recently been demonstrated to help prevent the development of or slow the progression of diabetic nephropathy, including blood pressure control, blood sugar control, and treatment with ACE inhibitors. Dietary protein restriction may also be of benefit. Multiple new interventions are undergoing clinical trials currently.
