Azithromycin, Ureaplasma and chronic lung disease of prematurity: a case study for neonatal drug development

Abstract

Chronic lung disease of prematurity (CLD) remains a major cause of morbidity and mortality in preterm infants. Ureaplasma has received intermittent attention over the last two decades as a possible contributory factor. In addition, pulmonary inflammation is associated with the development of CLD. The macrolide azithromycin provides an attractive option to determine if it can decrease the development of CLD as it has both anti-inflammatory and anti-infective properties. In this article, the authors review the evidence for the role of Ureaplasma in the development of CLD and the obstacles faced in the development of a drug before it reaches clinical practice.
