    Abstract:
    OBJECTIVES: Indirect hyperbilirubinemia during neonatal period is a common problem, and most preterm and more than half of the term neonates find this problem. Ursodeoxycholic acid (UDCA) protects the liver against oxidative stresses and prevents cellular apoptosis. In addition, it causes stimulation of bile flow, is well tolerated by the patient, and has limited side effects. Thus, the aim of this study was to investigate the effect of UDCA in treating neonates with unconjugated hyperbilirubinemia undergoing phototherapy. METHODS: In this randomized clinical trial, 220 neonates with unconjugated hyperbilirubinemia who referred to Amir-Kabir Hospital, Arak, Iran in 2017-2018, were randomly assigned to phototherapy group (Control group) and phototherapy plus UDCA group (Intervention group) as 10 mg/kg/day. The level of total bilirubin was measured at the baseline, and after 12, and 24 h using spectrophotometric, and the duration of receiving phototherapy was also measured in both groups. RESULTS: The mean age of included neonates in the control and intervention group was 5.3 and 4.9 days, respectively. The results revealed that after 12 h of treatment, the total bilirubin level in the control group had diminished by 2.70 mg/dL on average while, in the intervention group, the reduction was 3.7 md/dL (p = .001) and after 24 h of treatment, the total bilirubin level in the control group had diminished by 5.22 mg/dL on average and in the intervention group, the reduction was 6.54 md/dL (p = .001). It was also observed that there is no significant difference between groups in terms of the mean of the duration required for phototherapy (p = .63). CONCLUSIONS: UDCA combined with phototherapy enhances TSB decrease, but this effect is not relevant from a clinical point of view because it does not decrease phototherapy and hospital stay duration. Thus, this study does not support the UDCA use in the clinical practice. TRIAL REGISTRATION: IRCT, IRCT2017071515511N2.
