Total serum bilirubin levels during cyclooxygenase inhibitor treatment for patent ductus arteriosus in preterm infants.

AIM: To determine whether ibuprofen use in VLBW infants is associated with increased serum bilirubin levels and impaired neurodevelopmental outcome at 2 years of age compared to indomethacin.

METHODS

We retrospectively evaluated bilirubin data and outcome parameters of 178 VLBW infants treated with COX inhibitors for a haemodynamically relevant patent ductus arteriosus (PDA) between 1998 and 2003 in a single institution. In our department ibuprofen replaced indomethacin for PDA treatment in 2001, while clinical and echocardiographic criteria for the indication of PDA invention have remained unchanged.

RESULTS

Ibuprofen and indomethacin therapy groups did not differ in their baseline clinical profile. Peak serum bilirubin concentration was 10.2 mg/dL in the ibuprofen group and 8.6 mg/dL in the indomethacin group (p < 0.01), while phototherapy duration did not differ. At 2 years of age neurodevelopmental outcome was similar in both groups. In a single case analysis, four cases of adverse neurodevelopmental outcome despite inconspicuous clinical course were identified in the ibuprofen group.

CONCLUSION

In VLBW infants with PDA, ibuprofen treatment was associated with higher bilirubin levels than indomethacin.
