Efficacy and Safety of Rectal Ibuprofen for Patent Ductus Arteriosus Closure in Very Low Birth Weight Preterm Infants

Abstract

Background: To compare rectal ibuprofen with oral ibuprofen for the closure of hemodynamically significant patent ductus arteriosus (hsPDA) in very low birth weight (VLBW) preterm infants.Study design and subjects: In a prospective, randomized study, 72 VLBW infants who had hsPDA received either rectal or oral ibuprofen. The plasma concentration of ibuprofen and renal functions were determined in both groups by the high-performance liquid chromatography (HPLC) method and cystatin-C (cys-C), respectively.Results: The hsPDA closure rate of the group that received rectal ibuprofen was similar to oral ibuprofen (86.1% versus 83.3%) after the first course of the treatment (p=0.745). A statistically significant difference was identified between the mean plasma cys-C levels before and after treatment in both the rectal and oral ibuprofen groups (p=0.004 and p<0.001, respectively). The mean plasma ibuprofen concentration was similar in both groups after the first dose (rectal 44.0612.4; oral, 48.28 +/- 22.8) and the third dose (rectal, 45.34 +/- 24.3; oral, 48.94 +/- 24.8) (p>0.05 for all values).Conclusions: Rectal ibuprofen is as effective as oral ibuprofen for hsPDA closure in VLBW infants. The rise in the cys-C level with rectal and oral treatment shows that patients with borderline renal function should be evaluated and followed closely.
