Jaundice in a neonate with congenital diaphragmatic hernia.

ABSTRACT

A six-week-old boy presented to the emergency department with worsening jaundice. His medical history included congenital diaphragmatic hernia repaired shortly after birth. Significant jaundice, unresponsive to phototherapy, was noted on the eighth day of life. His total bilirubin level decreased when he was advanced to full oral feeds. However, on the 23rd day of life, the patient's conjugated bilirubin level had tripled. This was attributed to total parenteral nutrition, and the patient was discharged home. Over the next month, his jaundice worsened. The patient was readmitted and ultimately diagnosed with cytomegalovirus (CMV) hepatitis. After treatment with ganciclovir, his hepatitis completely resolved. CMV infection is a common cause of neonatal hepatitis and congenital malformation. Prolonged neonatal jaundice that does not improve with transitioning from total parenteral nutrition to oral feeds warrants further evaluation. Simple laboratory investigation can avoid unnecessary and potentially harmful medical and surgical interventions. Early treatment of neonatal CMV infection reduces the risk of long-term neurological and hepatic complications.
