Abstract
AbstractBackgroundBronchopulmonary dysplasia (BPD) remains a significant challenge in neonatal care. Prenatal inflammation and neonatal sepsis contribute to the multifactorial nature of BPD. A potential association between empirical antibiotic therapy and BPD risk has been proposed due to microbiota dysbiosis in very low birth weight premature infants.MethodsA single centered retrospective cohort study of preterm infants (24–32 weeks gestation) from 2014 to 2021. The study compared groups that received empirical antibiotics in the first days of life and those that did not receive any antibiotic in the first days of life. The primary outcomes studied were BPD, death, and the combined outcome of BPD/death. Statistical analysis employed t‐tests, Mann‐Whitney U, Chi‐square, and logistic regression.ResultsOf 454 preterm infants, 61.5% received antibiotics. This group had lower gestational age, birth weight, and Apgar scores. Antibiotic use was associated with higher incidence of BPD (35.5% vs. 10.3%), death (21.5% vs. 8.6%), and combined outcomes (54.5% vs. 18.3%). In multivariate analysis, antibiotic use independently associated with BPD (OR 2.58, p < 0.001) and combined outcome BPD/death (OR 2.06, p < 0.02). Antenatal corticosteroids provided protection against BPD, but not mortality.ConclusionThis study suggests an association between early empirical antibiotic use and BPD in preterm infants, emphasizing the need for judicious antibiotic practices in neonatal care.
