Newborn Jaundice Clinical Trials

Neonatal jaundice, or neonatal hyperbilirubinemia, is a common medical issue in the first two weeks of life, causing prolonged hospitalization and readmissions. It results from elevated total serum bilirubin (TSB) and is manifested as yellowish discoloration of the skin, sclera, and mucous membrane. Clinical jaundice appears in about 60% of term neonates and 80% of preterm infants within the first week of life. Pathologic hyperbilirubinemia occurs when bilirubin levels increase by more than 5 mg/dL/day or 0.2 mg/dL/hour, or when jaundice lasts longer than two to three weeks in full-term infants. In preterm infants, unconjugated hyperbilirubinemia is of particular concern due to their permeable blood-brain barrier and underdeveloped brain. Phototherapy is widely used to reduce or prevent the rise of serum unconjugated bilirubin levels and reduce the need for exchange transfusions. However, phototherapy has both immediate and long-term side effects, and it can only decrease accumulated UCB but does not prevent its accumulation. There is a growing potential to explore novel adjuvant treatments to increase bilirubin clearance, decrease phototherapy duration, and decrease exchange transfusion rate.
