Diabetic nephropathy: early detection, prevention and management.
Diabetic nephropathy typically presents more than a decade after diagnosis of diabetes and correlates with the duration of poorly controlled disease. Diabetic nephropathy begins as glomerular hypertension and hyperfiltration, followed by microalbuminuria and the development of hypertension, overt proteinuria, nephrotic syndrome, and a progressive decline in the glomerular filtration rate. Increasing expansion of the glomerular mesangium correlates with loss of function, resulting in uremia. This process eventually leads to the need for dialysis or renal transplantation in 30 percent of patients with insulin-dependent diabetes. By lowering intraglomerular pressure through enhanced glycemic control, inhibition of angiotensin and limitation of protein intake, severe nephropathy may be prevented, delayed or even partially reversed. Treatment must stress control of hypertension.
