Abstract:
Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.
