ABSTRACT
Objective To analyze the levels of IgE,TNF-α and FeNO in children with acute attack of bronchial asthma and their correlation with the severity of bronchial asthma, so as to provide theoretical basis for clinical evaluation of bronchial asthma. Methods A total of 547 children with acute bronchial asthma treated in Chengdu Women and Children's Central Hospital from January 2020 to December 2020 were selected and divided into mild group (n=287), moderate group (n=186) and severe group (n=74) according to the severity of their disease. All the children's symptoms were controlled after treatment. The serum IgE, TNF-α and FeNO levels in the experimental group were compared between the acute attack stage and the clinical control stage. Spearman correlation analysis was used to analyze the correlation between the serum IgE, TNF-α and FeNO levels and the severity of the disease. ROC curve of children with bronchial asthma was drawn to analyze the differential diagnosis value of serum IgE, TNF-α and FeNO levels in children with acute bronchial asthma. Results The levels of IgE, TNF-α and FeNO in acute stage were significantly higher than those in clinical control stage (P<0.05). The levels of serum IgE, TNF-α and FeNO in severe group were higher than those in mild and moderate groups significantly (P<0.05). The levels of serum IgE, TNF-α and FeNO in moderate group were higher than those in mild group significantly (P<0.05). Spearman correlation analysis showed that serum IgE, TNF-α and FeNO water were positively correlated with the severity of bronchial asthma (r=0.419 , 0.438 , 0.502 , P<0.05). ROC curve analysis showed that the AUC, sensitivity, accuracy and specificity of serum IgE, TNF-α and FeNO levels combined in diagnosing the severity of bronchial asthma in patients with acute attack was 0.938 (95% CI: 0.912-0.982 ), 83.47%, 92.06%, 94.28%. Conclusion The level of serum IgE, TNF-α and FeNO in children with acute attack of bronchial asthma is closely related to the severity of the disease, and combined detection of the three can be used to evaluate the severity of the disease in children.
ABSTRACT
ObjectiveTo compare and evaluate the clinical efficacy of five classical prescriptions for acute attack of bronchial asthma （BA） and cough variant asthma （CVA） in children， and to further compare and assess the effect of them on cold-induced asthma or heat-induced asthma. MethodRandomized controlled trials （RCT） on the treatment of acute attack of asthma with five classical prescriptions （Sanzi Yangqintang， Maxing Shigantang， Shegan Mahuangtang， Xiao Qinglongtang， and Dingchuantang） were retrieved from China Science and Technology Journal Database （VIP）， China National Knowledge Infrastructure （CNKI）， and Wanfang Data （from establishment to August 15， 2021）. The eligible RCT were evaluated and the data were extracted for network Meta-analysis by Stata 16.0. ResultA total of eligible 47 RCT were screened out， involving 5 114 children with acute attack of asthma and 10 intervention measures. Among them， 16 RCT （1 912 children， 6 intervention measures） were about the cold-induced asthma and 10 RCT （1 054 cases， 4 intervention measures） focused on the heat-induced asthma. According to the Meta-analysis， among the 10 interventions， Maxing Shigantang + routine treatment of western medicine demonstrated the most significant effect， and the effect of the interventions was in the following order： Maxing Shigantang + routine treatment of western medicine > routine treatment of western medicine， Shegan Mahuangtang + routine treatment of western medicine> Xiao Qinglongtang + routine treatment of western medicine > Shegan Mahuangtang > Dingchuantang + routine treatment of western medicine. For the cold-induced asthma， the effect of Shegan Mahuangtang + routine treatment of western medicine was remarkable， and for the heat-induced asthma， the corresponding intervention was Dingchuantang + routine treatment of western medicine. Shegan Mahuangtang was outstanding in improving the percentage of forced expiratory volume in the first second in predicted value （FEV1%）. ConclusionThe combination of western medicine with the five prescriptions was more effective than the western medicine alone， particularly the combination with Maxing Shigantang. The combination of Shegan Mahuangtang and western medicine was outstanding in the treatment of cold-induced asthma， while the corresponding intervention for heat-induced asthma was the combination of Dingchuantang and western medicine. However， a large number of RCT with scientific design and higher quality are still needed to verify the conclusion.
