    Abstract:
    OBJECTIVE: To evaluate the efficacy and safety of nebulized pentoxifylline for reducing the duration of oxygen supplementation in extremely preterm neonates at high risk of bronchopulmonary dysplasia (BPD). STUDY DESIGN: Single-center, randomized, double-blind, placebo-controlled trial was conducted. Infants of 23(0) to 27(6) weeks' gestational age requiring mechanical ventilation or ≥30% supplemental oxygen on continuous positive airway pressure at 72-168 hours were randomized to receive 20 mg/kg (1 mL/kg) nebulized pentoxifylline or an equal volume of normal saline placebo every 6 hours for 10 consecutive days via a vibrating mesh nebulizer. The primary outcome was the duration of oxygen supplementation at 40 weeks' postmenstrual age. We used Cox proportional hazards regression modeling to analyze outcomes. RESULTS: All infants had adequate data for analysis of the primary outcome. Intention-to-treat analysis revealed no differences in duration of oxygen supplementation at 40 weeks' postmenstrual age between pentoxifylline (n=41) and placebo (n=40) groups (median 2262 vs 2160 hours, adjusted hazard ratio: 1.14, 95% CI 0.72-1.80, P=.63). There was no difference in mortality and further secondary outcomes. No adverse effects were noted. CONCLUSIONS: Nebulized pentoxifylline is safe but did not reduce the duration of oxygen supplementation in extremely preterm infants at high risk of BPD. Dose-ranging studies and large, well-designed clinical trials are required to determine whether the use of nebulized or systemic pentoxifylline as a prophylactic therapy offers small but relevant benefits for prevention of BPD.
