Long term phototherapy in Crigler-Najjar syndrome

Area of Science:

• Biochemistry
• Genetics
• Pediatrics

Background:

• Crigler-Najjar syndrome type 1 is a rare genetic disorder characterized by severe unconjugated hyperbilirubinemia.
• This condition results from a deficiency in the UGT1A1 enzyme, crucial for bilirubin conjugation.
• Lifelong management is required due to the risk of severe neurological complications, including kernicterus.

Observation:

• A 10-year-old female patient with genetically confirmed Crigler-Najjar syndrome type 1.
• The patient has undergone daily phototherapy since birth.
• General physical and neurological development have been monitored and assessed as normal.

Findings:

• Consistent daily phototherapy has successfully controlled unconjugated hyperbilirubinemia in this patient.
• The treatment regimen has prevented the neurotoxic accumulation of bilirubin.
• Normal physical growth and neurological milestones were achieved and maintained throughout childhood.

Implications:

• Daily phototherapy represents a viable, long-term management strategy for Crigler-Najjar syndrome type 1.
• Early and consistent intervention can prevent severe bilirubin-induced neurological damage.
• This case underscores the importance of lifelong adherence to phototherapy for affected individuals.
