Effect of intravenous immunoglobulin on the management of Rh- and ABO-mediated hemolytic disease of the newbornBackground Regarding the close association between neonatal hyperbilirubinemia and occurrence of pathological jaundice as a cause of neurotoxicity and kernicterus, the present study aimed to evaluate the use of intravenous immunoglobulin (IVIG) in neonates with hyperbilirubinemia.
Methods A retrospective case-control study of blood group O mothers and their ABO and Rh newborns was conducted. Medical records that included total serum bilirubin levels of 79 patients with hemolytic disease of the newborn (HDN) from between 2017 and 2020 were reviewed. Neonates who were eligible to receive immunoglobulin based on the American Academy of Pediatrics (AAP) guidelines were classified as cases and the rest were included as the Control Group.
Results The mean total bilirubin in relation to hemoglobin levels in IVIG-treated neonates was significantly lower than in non-IVIG-treated neonates (13.98 ± 4.23 mg/dL versus 16.61 ± 2.68 mg/dL; p-value = 0.002). Although females had longer hospitalizations in both IVIG-treated (3.81 ± 1.28 versus 3.54 ± 1.30 days; p-value = 0.509) and non-IVIG-treated (3.43 ± 0.811 versus 3.19 ± 0.75 days; p-value = 0.361) groups compared to males, this difference was not significant between the groups. Although four neonates with ABO incompatibility required packed red blood cells, all infants were managed medically and no deaths occurred during the course of treatment. Moreover, no exchange transfusion or adverse effects of IVIG were observed.
Conclusion The results from the present study revealed that IVIG administration is a useful procedure for the management of bilirubin encephalopathy with greater opportunity to reduce exchange transfusion requirements for neonatal hyperbilirubinemia.
