Pregnancy induced hemolytic anemia: An unexplained entity

We present the case of a young primigravida who developed severe life threatening hemolytic anemia in the last trimester of three successive pregnancies with spontaneous recovery after each delivery and remained normal during the entire nongravid state. Corticosteroid and high-dose intravenous immunoglobulin therapy, although reported as useful, was ineffective in our case. She was managed only with the support with top-up blood transfusions. Extensive investigations were carried out to determine the cause of hemolysis, but these proved unfruitful. Fewer than two scores of such cases have been described in the literature. The paucity of such cases merits its presentation. It is suggested that this anemia should be referred to as "pregnancy-induced hemolytic anemia".
