Abstract:
Objective To explore the expression levels of NOD-like receptor thermal protein domain-asso-ciated protein 3(NLRP3)and interleukin-6(IL-6)in children with bronchial asthma combined with pulmona-ry infection and its relationship with prognosis.Methods A sample of 150 children with bronchial asthma combined with pulmonary infection hospitalized in Nanjing University Medical College Teaching Hospital,North Jiangsu People's Hospital from January 2021 to December 2022 were prospectively enrolled as observa-tion group,All children were followed up for one year.Another 164 healthy children underwent health check-ups were concurrently selected as control group.According to the prognosis,the children in the observation group were divided into good prognosis groups(n=92)and poor prognosis groups(n=58).Serum IL-6 and NLRP3 expression levels were detected in all participants,and receiver operating characteristic(ROC)curve was plotted to evaluate the value of IL-6 and NLRP3 in predicting the poor prognosis in children with bronchi-al asthma combined with pulmonary infection.Results Serum IL-6 and NLRP3 expression levels in the obser-vation group were significantly higher than those in the control group(P<0.05).Serum IL-6 and NLRP3 ex-pression levels in the poor prognosis group were higher than those in the good prognosis group(P<0.05).The results of ROC curve analysis showed that the area under the curve of IL-6 alone for predicting the poor prognosis of children with asthma combined with pulmonary infection was 0.772,with a sensitivity of 79.3%and a specificity of 73.9%.The area under the curve(AUC)of NLRP3 alone for predicting the poor prognosis of children with asthma combined with pulmonary infection was 0.735,with a sensitivity of 55.2%and a spe-cificity of 88.0%.The AUC of the combination of IL-6 and NLRP3 for predicting poor prognosis in children with asthma combined with pulmonary infection was 0.851,which was higher than those of IL-6 and NLRP 3 alone for predicting poor prognosis in children(Z=1.563,2.003,P=0.059,0.045),and the sensitivity was 82.8%and specificity was 75.0%,with high predictive value.Conclusion The expression levels of serum IL-6 and NLRP3 is abnormally up-regulated in children with bronchial asthma combined with pulmonary infec-tion,and the two could serve as predictive indicators for poor prognosis.
