Oral zinc or ursodeoxycholic acid with phototherapy for newborn jaundice

Efficacy and Safety of Oral Zinc Sulphate and Ursodeoxycholic Acid as Adjuvants to Phototherapy in Management of Neonatal Non-Hemolytic Unconjugated Hyperbilirubinemia

Phase 4 Interventional Future University in Egypt · NCT06517862

This will test whether adding oral zinc sulfate or ursodeoxycholic acid to phototherapy helps newborns (≥32 weeks) with non‑hemolytic jaundice lower their bilirubin faster and safely.

What this trial studies

This phase 4 interventional trial gives newborns with unconjugated non‑hemolytic hyperbilirubinemia standard phototherapy plus an oral adjuvant (either zinc sulfate or ursodeoxycholic acid) while tracking outcomes. Eligible neonates are ≥32 weeks gestation, tolerating enteral feeds, and requiring phototherapy; key exclusions include hemolytic jaundice, recent exchange transfusion, seizures, hydrops, hypoxic‑ischemic encephalopathy, major anomalies, or drug hypersensitivity. Investigators will monitor total serum bilirubin, duration of phototherapy, need for exchange transfusion, and adverse events to determine safety and whether bilirubin declines more quickly. The trial is carried out at the Neonatal Intensive Care Unit of Ain Shams University Hospitals in Cairo.

Who should consider this trial

Good fit: Newborns born at ≥32 weeks with unconjugated non‑hemolytic jaundice who require phototherapy and can tolerate enteral feeding are the intended participants.

Not a fit: Infants with hemolytic causes of jaundice, major neonatal complications (seizures, hydrops fetalis, hypoxic‑ischemic encephalopathy), prior exchange transfusion within 24 hours, known allergy to the study drugs, or gestational age under 32 weeks are excluded and unlikely to benefit.

Why it matters

Potential benefit: If successful, adding these oral drugs could shorten phototherapy time, speed bilirubin reduction, and lower the need for exchange transfusion or extended hospital stays.

How similar studies have performed: Some small clinical studies and biological rationale suggest zinc or ursodeoxycholic acid might reduce enterohepatic bilirubin recycling or speed bilirubin decline, but overall clinical evidence is limited and mixed.
