Rethinking hyperbilirubinemia: Gilbert syndrome in children with cystic fibrosis, a case report.

Cystic Fibrosis leads to liver complications, including cystic fibrosis liver disease but hyperbilirubinemia in CF patients on CFTR modulators is less understood. This article describes two pediatric CF patients on Elexacaftor/Tezacaftor/Ivacaftor therapy with elevated bilirubin, ultimately diagnosed with Gilbert syndrome, highlighting the importance of fractionated bilirubin testing for early diagnosis and management.
