Evaluation of the Effect of Oral Clofibrate Intake on Neonatal Total Serum Bilirubin: a Randomized Clinical Trial

Background: Clofibrate is a pharmacological agent, which affects the lipid metabolism. This compound could be involved in bilirubin accumulation and excretion process. Therefore, this study aimed to evaluate the effect of oral clofibrate intake on total serum bilirubin (TSB) of neonates hospitalized at Khatam Hospital. Methods: This clinical trial was conducted on 73 neonates with hyperbilirubinemia. Samples were divided into clofibrate (n=41) and control (n=32) groups. In the Clofibrate group, samples were given a single oral dose of 100 mg/kg clofibrate, whereas the control group received distilled water in an equal amount and color as placebo. Birth weight, type of delivery, gender, age and primary TSB level were recorded prior to the intervention and TSB was measured 24, 48 and 72 hours after the intervention. Results: In this study, no significant difference was observed between the groups on the first and third day of intervention in terms of mean TSB in neonates. However, a significant reduction was found on the second day in mean TSB of neonates, who received clofibrate (P=0.04). Conclusion: According to the results of this study, application of clofibrate was associated with faster alleviation of mean TSB and shorter duration of hospital stay without major side effects. Therefore, it is recommended that clofibrate be only used for clinical management of neonatal hyperbilirubinemia.
