Objective: The objective of the study was to determine the clinical utility of brain natriuretic peptide (NT-proBNP) for prediction of moderate to severe bronchopulmonary dysplasia (BPD). We hypothesized that elevated NT-proBNP levels at 4 weeks of postnatal age may predict the severity of BPD in preterm infants. Study Design: The study design was a prospective observational study. The research team enrolled and followed a cohort of 70 infants with gestational age less than or equal to 30 weeks. The plasma NT-proBNP levels were measured at the postnatal day 28th. We further followed and categorized infants into two groups. Infants with no or mild BPD (Group 1) and infants with moderate or severe BPD (Group 2). We compared plasma NT-proBNP levels at 28th day of postnatal life between Groups 1 and 2. The difference in NT-proBNP levels on day 28th between groups was used to predict the severity of BPD. Results: Plasma NT-proBNP was significantly elevated in Group 2 compared with Group 1, median (IQR) of 845 pg/mL (553, 1632) compared with 726 pg/mL (391, 923), P = 0.02. NT-proBNP had a fair predictive accuracy (C statistics of 0.68) to determine moderate to severe BPD. Conclusion: NT-proBNP may be a useful biomarker in conjunction with clinical factors as a predictor of severe BPD. For future directions, the trend of NT-proBNP in infants with BPD may have clinical significance in monitoring of the disease.
