Abstract:
Objective To explore the relationship between amyloid A(SAA)/C-reactive protein(CRP)and airway inflammation and disease severity in children with acute exacerbation of bronchial asthma.Methods A total of 82 children with acute exacerbation of bronchial asthma admitted to Anhui Provincial Children's Hospital from July 2020 to July 2023 were selected as the study objects,and were divided into mild group(23 cases)and moderate and severe group(59 cases)according to the disease severity at admission.SAA/CRP and airway inflammation indicators[interleukin-6(IL-6),procalcitonin(PCT)]in the two groups were compared.Receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of SAA/CRP for the disease severity of children with acute exacerbation of bronchial asthma,and multivariate Logistic stepwise regression analysis was used to explore the influencing factors for the disease severity of children with acute exacerbation of bronchial asthma.Results The serum levels of IL-6 and PCT in the mild group were lower than those in the moderate and severe group(P＜0.05),and the serum SAA,CRP and SAA/CRP in the mild group were lower than those in the moderate and severe group(P＜0.05).SAA/CRP was positively correlated with IL-6 and PCT levels in children with acute exacerbation of bronchial asthma(r=0.317,0.324,P=0.010,0.001).The area under the curve of SAA,CRP and SAA/CRP for diagnosing the disease severity of children with acute exacerbation of bronchial asthma were 0.854,0.753 and 0.916,re-spectively.Family history of asthma(OR=3.622,95％CI:1.556～8.430),asthma control test score(OR=4.175,95％CI:1.652-10.550),SAA/CRP(OR=5.254,95％CI:2.108-13.097)were the risk factors for children with acute exacerbation of bronchial asthma(P＜0.05).Conclusion The SAA/CRP in children with acute exacerbation of bronchial asthma is related to airway inflammation,and has a certain value in evaluating the disease severity of children with acute exacerbation of bronchial asthma.
