Abstract

ABO and Rh incompatibility are the leading causes of hemolytic disease of the fetus and newborn (HFDN). Due to the high antigenicity of the D antigen, hemolysis and symptoms progress rapidly. However, minor blood group incompatibility manifests varying clinical symptoms, from asymptomatic cases to neonatal jaundice and fetal hydrops. This study presents a case of HFDN in which anti-C and anti-e antibodies were identified and treated with intensive phototherapy. A full-term infant weighing 3,100 g at birth, with no complications during delivery, presented with jaundice and was admitted for intensive phototherapy. Antibody testing detected anti-C and anti-e antibodies in the neonate and the mother. The patient responded well to phototherapy, and intravenous immunoglobulin was administered. The total bilirubin levels decreased, and the infant was discharged after 5 days. At the age of 12 months, the infant exhibited normal neurodevelopment. In conclusion, neonates with HFDN, due to rare minor blood incompatibility, specifically anti-C and anti-e antibodies, can mitigate hyperbilirubinemia using phototherapy. Future research should also consider the severity of the minor blood group incompatibility.
