Oral fenofibrate for hyperbilirubinemia in term neonates: A single-blind randomized controlled trial.

BACKGROUND

Hyperbilirubinemia is common in the neonatal period; however, delayed diagnosis or inadequate treatment can cause irreparable damage to the neonates. We aimed to evaluate the efficacy of oral fenofibrate for hyperbilirubinemia in term neonates.

METHODS

This single-blind randomized controlled trial included 86 term neonates aged 3-7 days, with birth weight ≥2500 g, admitted to Bandar Abbas Children's Hospital, Bandar Abbas Iran, from July 23, 2019, to July 22, 2020. The fenofibrate group received 10 mg/kg oral fenofibrate and phototherapy, while controls only received phototherapy. Serum total bilirubin was measured at 24 and 48 h and at the time of discharge. Hospital length of stay was also noted.

RESULTS

The two study groups were comparable regarding age, gender, gestational age, birth weight, and baseline total serum bilirubin levels. Serum total bilirubin levels at 48 h (P < 0.001) and at discharge (P < 0.001) were significantly lower in the fenofibrate group compared to controls. Although hospital length of stay was lower in the fenofibrate group compared to controls, the difference was not statistically significant (P = 0.612). Fenofibrate was more effective on the reduction of serum bilirubin in neonates aged 3-4.5 days starting at the 24th hour. Moreover, it was more effective in female neonates compared to males starting at the 48th hour.

CONCLUSIONS

A single dose of oral fenofibrate reduced total serum bilirubin in term neonates with hyperbilirubinemia without any side effects; however, this effect was more prominent after 48 h.
