Neurodevelopmental outcome after COX inhibitor treatment for patent ductus arteriosus.

AIM

To compare neurodevelopmental results in very low birth weight (VLBW) infants two years after successful or failed cyclooxygenase inhibitor treatment with either indomethacin or ibuprofen for a haemodynamically significant patent ductus arteriosus (hsPDA).

METHODS

We retrospectively evaluated closure rates and outcome parameters of VLBW infants with hsPDA 89 of whom were treated with indomethacin and 93 with ibuprofen.

RESULTS

Indomethacin and ibuprofen therapy groups did not differ in their baseline clinical profile (median gestational age 26.0 and 26.2wksd) in early (median CRIB 6 and 5, respiratory distress >2 degrees in 36 and 34 infants) and late morbidities (intraventricular hemorrhage >2 degrees in 9 and 10 infants, bronchopulmonary dysplasia in 31 and 27 infants, 80 and 85 survivors), PDA closure rates (63 and 58%) or neurodevelopmental outcome. The therapy failure group (54 infants) was characterized by lower median gestational age (25.0wksd) and higher mortality (17%). No differences were found in the neurodevelopmental outcome of the surviving infants with ligation as compared to the survivors with successful pharmacological closure of the PDA at 24months corrected age.

CONCLUSION

Use of either ibuprofen or indomethacin for closure of a hsPDA did not influence two year neurodevelopmental outcomes in VLBW infants.
