Abstract

Patients with Crigler-Najjar Type 1 (CN-1) disorder have an unconjugated hyperbilirubinaemia due to the complete absence in activity of uridinediphosphate glucuronosyltransferase, a bilirubin-conjugating enzyme. In pregnant women with CN-1, the foetus is at high risk of being adversely affected by the bilirubin, as unconjugated bilirubin can cross the placenta and is potentially neurotoxic. We report the long-term outcomes of two infants born to women with CN-1. These infants had exchange transfusions soon after birth and have normal neurodevelopmental outcomes at 18 months and four years of age, respectively. We propose that this intervention might have improved the neurological outcome of these infants.
