Effect of medical therapy on progressive nephropathy: influence of pregnancy, diabetes and hypertension.

Nephropathy is a complication of diabetes mellitus that can affect women in their reproductive years. This article reviews the effects on treatment on the main factors associated with short- and long-term complications in pregnant women with diabetic nephropathy. Tight glycemic control, adequate treatment of elevated blood pressure, and renal function in early pregnancy are the most significant predictors of maternal and perinatal outcomes. Contemporary methods of perinatal care and adequate treatment of blood pressure allow fetal survival rates of 95%. Furthermore, pregnancy per se does not appear to worsen the natural progression to end-stage renal disease for most women with renal insufficiency. However, patients with moderate to severe renal impairment may experience acceleration of renal disease.
