Medical, Administrative, Financial, and Social Challenges in the Management of a Case of Hemolytic Disease of the Fetus Caused by a Rare Alloantibody in a Low-Resource Setting.

Antibodies to high-frequency antigens are rarely implicated in cases of hemolytic disease of the fetus and newborn (HDFN), yet they pose a challenge to both clinical staff and transfusion medicine, especially with the identification of the implicating antibody and the arrangement of compatible blood for intrauterine transfusion. Here we report one such interesting case of HDFN caused by an alloantibody to a high-frequency antigen belonging to the Rhesus (Rh) blood group system. The patient presented at the 19th week with Rh-isoimmunized pregnancy. She received six intrauterine transfusions (IUTs) at different intervals during the antenatal period. Arranging the blood of this rare blood group required great efforts from hospital administration, clinicians, and social workers. At 31 weeks, the fetus developed a non-reassuring non-stress test (NST). Hence, the baby was delivered by cesarean section. The baby fared well in the neonatal period. With great efforts and support from social health workers, the Japanese Red Cross society, the administration, and non-government organizations, the impossible became possible.
