Abstract
Aim
To see the efficacy of intravenous immunoglobulin (IVIg) in reducing the need for exchange transfusion (ET) in neonates with isoimmune hemolytic disease with serum bilirubin at or above exchange level.
Methods
Retrospective cohort study conducted in neonatal intensive care unit of a tertiary care center from March 2015 to February 2020 included neonates with gestational age ≥35 weeks with positive Direct Coombs Test with serum bilirubin at or above exchange level according to American Academy of Pediatrics charts with no bilirubin encephalopathy at presentation. Study subjects were followed till discharge.
Results
ET was prevented in 8/41 (19.5%) cases who received IVIg initially vs. 2/51 cases (3.92%) who didn’t (P = .02, relative risk: 1.98 with 95% confidence interval [1.32-2.98] with number needed to treat: 2.51). Total duration of phototherapy was significantly lesser in those receiving IVIg (P < .0001).
Conclusion
Targeted use of IVIg in isoimmune hemolytic disease of newborn with serum bilirubin rising despite intensive phototherapy or within 2 to 3 mg/dL of the exchange level is more likely to benefit than harm and remain prudent.
