Severe perinatal hemolytic disease due to anti-e.

Maternal antibody-mediated fetal red blood cell destruction secondary to non-D Rh system antibodies is a significant cause of hemolytic disease of the fetus and newborn. Here, we report a rare case of severe perinatal hemolytic disease associated with maternal antibody to the e antigen. In addition to severe anemia, the infant developed hyperbilirubinemia. Resolution of the infant's anemia and hyperbilirubinemia occurred after treatment with phototherapy, intravenous immunoglobulin, and transfusion.
