- Abstract: Objective To evaluate the predictive value of serum microRNA-19a-3p(miR-19a-3p),microRNA-146a(miR-146a)and 25-hydroxyvitamin D3[25-(OH)D3]for the prognosis of children with respiratory syncytial virus(RSV)bronchiolitis.Methods A total of 202 children with RSV bronchiolitis were enrolled as disease group,followed up for one year after discharge,and divided into good prognosis group(n=55)and poor prognosis group(n=147).Additionally,180 healthy chil-dren matched by gender and age were selected as control group.Serum levels of miR-19a-3p,miR-146a and 25-(OH)D3 were measured in both the disease and control groups.The clinical data and the levels of serum miR-19a-3p,miR-146a and25-(OH)D3 of children in the poor prognosis group and the good prognosis group were compared.The correlations of serum miR-19a-3p,miR-146a and 25-(OH)D3 with the prognosis of children and their predictive value for poor prognosis of chil-dren were analyzed.Multivariate Logistic regression analysis was used to screen the related influen-cing factors of poor prognosis in children.Results The proportion of smoking among family mem-bers,the expression levels of serum miR-19a-3p and miR-146 in the poor prognosis group were sig-nificantly higher than those in the good prognosis group,and the level of 25-(OH)D3 was signifi-cantly lower than that in the good prognosis group(P＜0.05).The expression levels of serum miR-19a-3p and miR-146a were positively correlated with the poor prognosis of the children(r=0.408,0.332,P＜0.001),and the level of serum 25-(OH)D3 was negatively correlated with the poor prognosis of the children(r=-0.386,P＜0.001).The results of receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC)of serum miR-19a-3p,miR-146a and 25-(OH)D3 for predicting poor prognosis in children was 0.726,0.817 and 0.834,re-spectively.The AUC of the combined prediction of the three was 0.938,which was higher than that of the single prediction(Z=5.515,3.879,3.860,P＜0.001),and the sensitivity and specificity were 83.64％and 90.48％,respectively.The miR-19a-3p,miR-146a,25-(OH)D3 and smoking among family members were all influencing factors for the poor prognosis of children with RSV bron-chiolitis(P＜0.05).Conclusion Serum miR-19a-3p,miR-146a and 25-(OH)D3 all have cer-tain predictive values for the prognosis of children with RSV bronchiolitis,and the combined predic-tive value of the three is higher.
