Abstract:
OBJECTIVE To explore the expressions of eosinophilic chemotactic factor 11(CCL11),leukotriene B4(LTB4),percentage of neutrophils(NEUT％)and C-reactive protein(CRP)in peripheral blood of the children with Mycoplasma pneumoniae(MP)infection complicated with plastic bronchitis and analyze the clinical signifi-cance.METHODS A total of 80 children with MP pneumonia complicated with plastic bronchitis who were trea-ted in the Second Hospital of Longyan City,Fujian Province from Jan.2020 to Dec.2023 were assigned as the study group,and 115 patients with MP pneumonia were chosen as the control group.The clinical data,manifesta-tions and Pediatric Risk of Mortality Ⅲ(PRISM Ⅲ)score were statistically analyzed.The levels of peripheral blood CCL11,LTB4,NEUT％and CRP were observed and compared between the two groups.Pearson analysis was performed for the associations of the levels of CCL11,LTB4,NEUT％and CRP with the PRISM Ⅲscore.The value of the joint detection of CCL11,LTB4,NEUT％and CRP in diagnosis of the MP pneumoni-a-induced plastic bronchitis was analyzed.RESULTS There were significant differences in reduction of bronchial breathing sound,pleural effusion and PRISM Ⅲ score between the two groups(P＜0.05).There were significant differences in the levels of peripheral blood CCL11,LTB4,NEUT％and CRP between the study group and the control group(P＜0.05);the CRP level of the study group was(29.42±8.14)mg/L,higher than that of the control group(t=10.138,P＜0.001).The levels of CCL11,LTB4,NEUT％and CRP were positively correlated with the PRISM Ⅲ score(r=0.723,0.710,0.771,0.754,respectively,all P＜0.001).The area under the curve(AUC)of the single detection of CCL11,LTB4,NEUT％and CRP was remarkably higher in diagnosis of MP pneumonia-induced plastic bronchitis than that of the joint detection of the four markers(P＜0.05).CONCLUSIONS The children with MP pneumonia complicated with plastic bronchitis show increased expressions of CCL11,LTB4,NEUT％and CRP.The four markers are positively correlated with the PRISM Ⅲ score.The four markers have high values in diagnosis of the MP pneumonia complicated with plastic bronchitis.
