- Abstract: Objective To investigate serum levels of eosinophilic neurotoxin(EDN),interleukin(IL)-13 and transforming growth factor(TGF)-β1 in children with recurrent wheezing of mycoplasma pneumoniae(MP)infection and analyze risk factors of recurrent wheezing with MP infection.Methods A total of 80 children with MP infection were divided into the MP infection recurrence wheezing group(45 cases)and the MP infection non-wheezing group(35 cases)according to the previous history of MP infection with wheezing,and 35 children with acute attacks of bronchial asthma were selected as the asthma group.The levels of EDN,IL-13 and TGF-β1 were determined by enzyme-linked immunosorbent assay.Multivariate Logistic regression analysis was performed to analyze risk factors of MP infection recurrence and wheezing.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of EDN,IL-13 and TGF-β1 on MP infection recurrence and wheezing.Results Compared with the non-asthmatic group,levels of EDN,IL-13 and TGF-β1 were higher in the recurrent asthmatic group and the asthmatic group(P＜0.05).There were no significant differences in EDN,IL-13 and TGF-β1 levels between the asthma group and the recurrent asthmatic group.Univariate analysis showed that the birth weight was lower in the recurrent wheezing group than that of the non-wheezing group,and the proportion of atopic constitution,the first and second degree relatives allergy history,smoke exposure and hospital stay≥7 d were higher than those of the non-wheezing group(P＜0.05).Multivariate Logistic regression analysis showed that higher levels of EDN,IL-13,TGF-β1,atopic constitution and smoke exposure were risk factors for recurrent wheezing of MP infection(P＜0.05).ROC curve results showed that the AUC of EDN,IL-13 and TGF-β1 for predicting the recurrence of MP infection and wheeting was 0.688,0.662 and 0.689,respectively,and the AUC of the combined prediction of EDN,IL-13 and TGF-β1 was 0.765,which was the most effective than each single index.Conclusion Serum levels of EDN,IL-13 and TGF-β1 increase in children with recurrent wheezing of MP infection,and their serum levels may predict repeated wheezing in children after MP infection,providing guidance for clinical intervention.
