Clofibrate as an Adjunct to Phototherapy for Unconjugated Hyperbilirubinemia in Term Neonates.

Abstract

To evaluate the efficacy of oral clofibrate as an adjunct to phototherapy for unconjugated hyperbilirubinemia in term neonates. This randomized controlled trial was done in the level III neonatal intensive care unit (NICU) of a tertiary care hospital. Ninety term neonates with unconjugated hyperbilirubinemia with serum bilirubin 15-25 mg/dl were randomized to either intervention group (single dose of clofibrate in a dose of 50 mg/kg prior to starting phototherapy) or standard care group (only phototherapy). Primary outcome was absolute fall in bilirubin by 48 h. Secondary outcomes were duration of phototherapy, absolutefall in bilirubin levels at 12, 24, 36, 48 h, need for exchange transfusion and incidence of side-effects. After 48 h of intervention, significantly lower bilirubin levels were noted in the intervention group compared to standard care group with a mean difference of 7 mg/dl (95% CI 6.7 mg/dl to 7.2 mg/dl). Duration of phototherapy required was less in the intervention group compared to standard care group with mean difference of 23.82 h (95% CI 30.46 h to 17.18 h). Exchange transfusion was needed for 4 neonates in the standard care group and none in the intervention group. No side-effects were noted with clofibrate. Single dose clofibrate prior to starting phototherapy in term neonates with uncomplicated unconjugated hyperbilirubinemia reduces the duration of phototherapy significantly.
