ABSTRACT
High neonatal bilirubin is a common phenomenon responding to phototherapy. We report a case of a newborn with a highly elevated bilirubin of 37.3 mg/dL due to ABO incompatibility between the mother (Group O) and the newborn (Group A) requiring whole blood exchange, a procedure performed rarely to treat newborn hyperbilirubinemia. The newborn (38.8 weeks of gestation) initially showed a total bilirubin of 8.4 mg/dL and was discharged after being stabilized by phototherapy. However, the baby returned to the hospital with highly elevated bilirubin and was admitted to the Neonatal Intensive Care Unit (NICU). Emergent reconstituted whole blood exchanger therapy was initiated due to refractoriness to phototherapy and IVIG. Markedly elevated anti-A titer was found in the mother's blood (1512) and cord blood (1128). The baby was stabilized and eventually discharged with a serum bilirubin of 13.8 mg/dL. This case demonstrates the possible predictive value of mother/cord blood anti-A titers in severe newborn hyperbilirubinemia, which may prevent premature discharge and trigger early initiation of lifesaving therapy.
