    Oral riboflavin enhances phototherapy for neonatal jaundice. This treatment, combined with blue light, significantly increases bilirubin reduction in infants compared to phototherapy alone.

    Area of Science:

    • Neonatal Medicine
    • Biochemistry
    • Photobiology

    Background:

    • Neonatal jaundice, a common condition, requires effective treatment to prevent complications.
    • Phototherapy using blue light is a standard treatment for hyperbilirubinemia.
    • Riboflavin (vitamin B2) is being investigated as an adjunct to phototherapy.

    Purpose of the Study:

    • To evaluate the efficacy of oral riboflavin in enhancing phototherapy for neonatal jaundice.
    • To determine the effect of riboflavin on bilirubin levels during blue light treatment.
    • To explore the relationship between blue light energy, riboflavin, and bilirubin reduction.

    Main Methods:

    • A randomized study of 24 jaundiced neonates, divided into treatment (riboflavin) and control groups.
    • Phototherapy administered with blue light (420-470 nm) at varying energy levels (6-10 μW/cm²).

  • Comparison of 24-hour bilirubin decrease in riboflavin-treated infants versus controls, considering light energy dose.

    • Main Results:

    • Riboflavin-treated infants receiving lower blue light energy showed bilirubin decrease similar to controls.
    • Infants receiving riboflavin with blue light energy equivalent to controls demonstrated a significantly greater bilirubin decline (5.2 mg/100 ml/24 hr).
    • The study indicates a synergistic effect between riboflavin and phototherapy.

    Conclusions:

    • Oral riboflavin can enhance the effectiveness of phototherapy in reducing neonatal bilirubin levels.
    • Further in vivo research is necessary to fully understand the implications of riboflavin as a photosensitizer, particularly concerning potential DNA effects.
    • Riboflavin shows promise as an adjunctive therapy for neonatal hyperbilirubinemia.
