Diabetic nephropathy has become the single largest cause of end-stage renal disease (ESRD) worldwide. Until recently, it was thought that once a patient developed overt proteinuria, diabetic nephropathy was irreversible and inevitably progressed to ESRD. However, the reversal of lesions caused by diabetic nephropathy (e.g., glomerular basement membrane thickening and mesangial matrix increase) has been demonstrated in a series of patients who underwent a pancreas transplantation 10 years prior to the reversal. Remission of nephrotic range proteinuria has also been reported in some patients with type 1 diabetes from the Collaborative Study Group during a median follow-up of 3 years of angiotensin-converting enzyme (ACE) inhibitor administration; no deterioration of renal function was observed in these patients. Remission and regression in nephropathy of type 1 diabetes patients have also been reported when blood pressure was controlled aggressively. Recent clinical trials have demonstrated that angiotensin II receptor blocker (ARB) preserved renal function and slowed the progression of nephropathy to ESRD in patients with type 2 diabetes. Since many patients with type 2 diabetes manifest with a metabolic syndrome, multifactorial intensive treatment is necessary; such treatment includes behavior modifications, dietary intervention, exercise, and smoking cessation. In this population, pharmacological therapy targeting hyperglycemia, hypertension (including ARB/ACE inhibitor), and hyperlipidemia in cases of type 2 diabetes is also necessary.
