A case report on non-D HDFN: Highlighting the role of antibody screening in RhD positive antenatal women

Bharat Singh, Rajendra Chaudhary, Preeti Elhence, Jyoti Kala Bharati, Anubha SrivastavaAsian Journal of Transfusion Science 2022 16(1):121-123 The widespread use of anti-D immunoglobulin has resulted in a relative increase in the importance of non-D alloimmunization as a cause of hemolytic disease of the fetus and newborn (HDFN). Non-D alloantibodies that are capable of causing severe HDFN include anti-K, anti-E, and anti-c. Anti-c is clinically the most important Rh system antibody after anti-D. Here, we report three cases of neonates presenting with anemia and hyperbilirubinemia with strongly positive direct antiglobulin test who required phototherapy and neonatal exchange transfusion due to non-D antibody in RhD positive antenatal women. Anti-c was common in all the three cases while two cases have one additional non-D antibody. Due to faulty practices, antenatal antibody screening was not done for any case considering the mother's RhD positive status. Hence, antenatal antibody screening should be performed routinely, in all RhD positive pregnant women to reduce the delay in diagnosis and the management of HDFN occurring due to non-D antibodies.
