Abstract:
Objective:To study the clinical value of N-terminal pro-B-type natriuretic peptide (NTproBNP) predicting the risk of bronchopulmonary dysplasia (BPD) in very/extremely low birth weight infants (VLBWI/ELBWI).Methods:From June 2017 to December 2019, VLBWI/ELBWI admitted to neonatal department in our hospital were enrolled in this non-interventional prospective study. According to the occurrence of BPD, the infants were assigned into BPD group and non-BPD group. Infants in BPD group were further assigned into mild, moderate and severe BPD groups. Plasma NTproBNP were measured on 14 d, 21 d, 28 d, 35 d, 42 d and 49 d after birth. Repeated-measures ANOVA was used to determine the differences of NTproBNP at different time points in each group.Results:A total of 190 infants were enrolled, including 36 cases in BPD group (18, 13 and 5 cases in mild, moderate and severe BPD group, respectively) and 154 cases in non-BPD group. The gestational age, birth weight and 5-min Apgar score in BPD group were lower than non-BPD group. BPD group had significantly higher incidences of retinopathy of prematurity, patent ductus arteriosus and necrotizing enterocolitis and significantly longer duration of invasive mechanical ventilation and noninvasive ventilation than non-BPD group ( P<0.05).No significant differences existed in NTproBNP levels between BPD group and non-BPD group on 42 d and 49 d ( P>0.05). At other time points, NTproBNP levels in BPD group were significantly higher than non-BPD group ( P<0.05). NTproBNP level in severe BPD group was the highest on 14 d. No significant differences existed in NTproBNP levels between mild and moderate groups on 28 d ( P>0.05). At other time points, NTproBNP in severe BPD group was higher than mild and moderate BPD groups ( P<0.001). The receiver operating characteristic curve analysis showed the best cut-off value of NTproBNP was 982 pg/ml on 14 d (AUC=0.907, 95% CI 0.831~0.983). Conclusions:VLBWI/ELBWI with BPD have higher levels of NTproBNP. And the more severe of BPD, the higher the NTproBNP level. NTproBNP has certain predictive values for BPD in VLBWI/ELBWI.
