Managing Crigler-Najjar Syndrome Type 2 During Pregnancy
Clinical Scenario
This protocol addresses pregnancy in female patients with
Crigler-Najjar syndrome type 2 (CNS2). Pregnancy in women with CNS is rare and presents unique
challenges for bilirubin control throughout each trimester.
Treatment Approach
Management involves a sequential protocol combining phototherapy and phenobarbital, with the
specific timing and duration adjusted across the stages of pregnancy.
Complete regimen, sequencing, and monitoring criteria available in the full protocol.
Clinical Goals
- Maintain maternal bilirubin levels below 11.7 mg/dL
- Keep the bilirubin/albumin ratio below 0.5

- Pregnancy in women with CNS is rare and presents unique challenges.
- Sequential treatment with phototherapy during the first trimester and phenobarbital in subsequent trimesters has been successfully used to manage bilirubin levels in pregnant women with CNS2.
- In CNS2 patients, combining phototherapy and phenobarbital can keep bilirubin levels within safe ranges.
- Regular monitoring and adjusting phototherapy duration are recommended to maintain maternal bilirubin levels below 11.7 mg/dL, with a B/A ratio below 0.5.
