Summary

We report a case of haemolytic disease of the fetus and newborn due to anti-S antibodies. Baby G was born by emergency caesarean section at 35 weeks due to reduced fetal movement. Prior to delivery, antenatal screening revealed the mother's blood group was AB rhesus positive with anti-S antibody titres. The baby was pale but non-hydropic at birth with hepatosplenomegaly. Haemoglobin at birth was 5.23 g/dl and serum bilirubin 138 µmol/l. The baby required phototherapy, γ-globulin infusion and exchange transfusion with post-transfusion complications.
