Postpartum hemolytic uremic syndrome in a 17-year-old Filipina primigravid.

A 17-year-old Filipina primigravid developed acute renal failure secondary to hemolytic uremic syndrome (HUS) after undergoing emergency cesarean section for severe pre-eclampsia and abruptio placenta. She underwent hemodialysis with concurrent infusions of fresh-frozen plasma and packed red cells for 5 weeks. Renal biopsy revealed findings consistent with HUS with glomerular crescents. She received three doses of pulse methylprednisolone followed by oral prednisone. Renal function improved 5 weeks after the onset of HUS. The pathogenesis, differential diagnosis, and treatment options of postpartum HUS are discussed.
