| Abstract |
PURPOSE
Neonatal immune hemolytic jaundice due to blood group incompatibility is important to treat properly because of an early rise and a high peak of serum bilirubin level and a risk of kernicterus. The conventional therapeutic modalities for neonatal immune hemolytic jaundice due to blood group incompatibility are phototherapy and exchange transfusion. We evaluated the effect of intravenous immune globulin (IVIG) therapy on hyperbilirubinemia due to ABO incompatibility.
METHODS
This study included 6 infants with hyperbilirubinemia due to ABO incompatibility who were admitted to the nursery of Eulji Medical Center, Nowon Hospital, from January 2000 to February 2001. All 6 infants had a positive direct Coombs test. Their serum bilirubin levels were above 12 mg/dl within 24hours of age and above 20 mg/dl after 24hours of age. They were treated with intensive phototherapy and IVIG.
RESULTS
We classified the effective group when a decline in serum bilirubin level was more than 2 mg/dl in 3-4 hours after IVIG therapy, and the ineffective group when there was a decline in serum bilirubin level less than 2 mg/dl, a re-rise after the initial response to IVIG, or a decline after the combined therapy with intensive phototherapy and IVIG equal or less than that after intensive phototherapy alone. In the effective group (n=2), the average decline in serum bilirebin level was 4.1 mg/dl in 3-4 hours and 8.1 mg/dl in 12-16 hours after IVIG therapy, while in the ineffective group (n=4), the average decline was 1.9 mg/dl and 2.7 mg/dl, respectively. Five among 6 infants were treated with IVIG therapy and 1 infant was treated with exchange transfusion. No serious side effect was detected during and after IVIG therapy.
CONCLUSION
We demonstrated the effectiveness of IVIG therapy in 2 infants out of six who were treated with intensive phototherapy and IVIG for hyperbilirubinemia due to ABO incompatibility. IVIG therapy could be considered if hyperbilirubinemia due to ABO incompatibility does not respond to intensive phototherapy alone. Further prospective and randomized studies would be needed. |
