Neonatal hyperbilirubinaemia necessitating exchange transfusion due to maternal sickle cell crisis

Abstract

Abstract Background Pregnancy in women with sickle cell disease (SCD) is associated with a number of fetal complications such as intra-uterine death, intra-uterine growth restriction (IUGR), preterm birth, low birth weight and an increased perinatal mortality and morbidity. Hyperbilirubinaemia necessitating exchange transfusion in an infant of a mother with SCD, to the best of our knowledge, has not been previously described. Case presentation An infant was delivered at 33 weeks and 5 days of gestation due to a maternal sickle cell crisis. The infant had an unconjugated bilirubin level of 153 μmol/L on admission to the neonatal intensive care unit at 30 min of age. Phototherapy was immediately commenced, intravenous immunoglobulin administered and then a double-volume exchange transfusion was performed. There was, however, no evidence of haemolysis in the infant and the infant’s haemoglobin level remained stable following the exchange. No further exchange transfusions were required. The mother had a high unconjugated bilirubin level (151 μmol/L) prior to delivery. Conclusion High neonatal unconjugated bilirubin levels necessitating exchange transfusion can occur due to haemolysis in the maternal circulation, in this case due to SCD.
