RESUMO
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.

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.
