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.
