Unusual presentation of mesangial proliferative glomerulonephritis in HELLP syndrome associated with acute renal failure

Acute renal failure in pregnancy is not common in industrialized countries. HELLP syndrome (hemolysis, elevated liver enzyme, and low platelets) was one of the causes of acute renal failure in pregnancy, but renal pathological findings in case of acute renal failure had rarely been reported. We reported an unusual case of HELLP syndrome with acute renal failure requiring renal replacement therapy and which histopathologic findings of kidney biopsy showed mesangial proliferative glomerulonephritis and her renal function completely recovered after immediate artificial abortion, supportive management, transfusion of blood products, and hemodialysis.
