A B S T R A C T Advances in neonatal intensive care have greatly improved survival rates for children born in a very early stage of lung development (i.e. less than 26 weeks of gestation). In these premature babies, even low levels of oxygen and methods of minimally invasive ventilation may disrupt the growth of the distal airways, a condition described as “new” bronchopulmonary dysplasia (BPD). Ureaplasma infection can occur in utero or in the perinatal period in premature infants, in some of which the infection with these organisms triggers an important lung pro-inflammatory and pro-fibrotic response, and may increase the risk of developing BPD. The inflammation may be worsened by exposure to oxygen and mechanical ventilation. At present, clinical studies have not clarified the role of Ureaplasma in the pathogenesis of BPD and there is insufficient evidence to determine whether antibiotic treatment of Ureaplasma has influence on the development of BPD and its comorbidities. Future research in the context of well-designed and controlled clinical trials of adequate statistical power should focus on how to determine whether the treatment of Ureaplasma decreases lung inflammation, reduces rates of BPD, and improves long-term neurodevelopment. © 2014 Elsevier Ireland Ltd.
