Start date July 2011
End date June 2013
Trial size 60 participants
Trial identifier NCT01516398, BPD22044


A lung condition called bronchopulmonary dysplasia (BPD) is a major cause of poor outcomes and death for premature infants. Infants with BPD are also at high risk for pulmonary hypertension (PH)—an important contributor to their condition. Previous research has suggested that a protein in the blood, endothelin-1 (ET-1), is associated with pulmonary disease.

This study aims to investigate the incidence of PH and levels of ET-1 among premature babies with BPD. It will also potentially allow us to focus further research efforts and treatment towards these infants, some of our sickest patients at LPCH.

Official title Endothelin-1 (ET-1) Levels as Predictors of Pulmonary Hypertension Risk in Premature Infants With Bronchopulmonary Dysplasia (BPD)
Principal investigator Christine Johnson, MD
Description This study aims to 1) investigate the incidence of PH among premature infants with BPD versus those without BPD and 2) investigate ET-1 levels in infants with BPD-associated PH versus those without BPD-associated PH. This study will allow us to help define a high-risk population at LPCH—namely, premature infants with BPD-associated PH. It will also potentially allow us to focus further research efforts and treatment targets towards these infants who encompass some of our sickest patients at LPCH. In 2009 the Division of Lung Diseases of the National Heart, Lung and Blood Institute (NHLBI) published seven priority areas for research in pediatric pulmonary diseases, one of which was pulmonary vascular disease. An emphasis was made on finding 'clinical strategies that anticipate the development of PH [which] may allow earlier recognition and more aggressive therapy, thereby slowing the development of PH in many chronic lung parenchymal and vascular diseases'. This study attempts to address this goal. Specifically we aim to evaluate ET-1 levels in premature infants diagnosed with BPD and with BPD-associated PH. If ET-1 levels are found to correlate with disease state the possibility of prediction and possible early treatment for PH in these infants is raised and merits investigation.
