Abstract:
Objective To analyze the relationship between serum exosomal microRNA(miR)-7-5p expression levels in children with asthma and their short-term prognosis.Methods A total of 132 asthmatic children(asthma group)and 30 healthy children(control group)from Tangshan Vocational & Technical College Affiliated Hospital between October 2021 and May 2023 were included as study subjects.These asthmatic children were categorized into a good prognosis group(n=91)and a poor prognosis group(n=41)based on their Childhood Asthma Control Test results.The levels of allergy history,forced vital capacity(FVC),fractional exhaled nitric oxide(FeNO),and miR-7-5p level among groups were compared,and logistic regression analysis was conducted to identify risk factors for the short-term prognosis of asthmatic children.The Kappa test,receiver operating characteristic(ROC)curve,and mean absolute error(MAE)value were used to evaluate indicators in predicting short-term prognosis in children with asthma.Results The level of miR-7-5p in the asthma group[0.53(0.49,0.64)]was lower than that in the control group[1.03(0.97,1.10)],with significant difference(Z=8.548,P＜0.001).The poor prognosis group exhibited a higher proportion of allergy history(68.29％)and FeNO[38(36,41)ppb]levels,and lower FVC[1.86(1.84,2.05)L]and miR-7-5p levels[0.47(0.43,0.52)]compared to the good prognosis group[46.15％,35(30,40)ppb,1.94(1.87,2.06)L,0.60(0.50,0.68)],and the differences were significant(x2/Z=2.854～6.450,all P＜0.05).Multivariate logistic regression analysis revealed that a history of allergies(OR=3.388,95％CI:1.328～8.643,P=0.011)and high FeNO levels(OR=1.161,95％CI:1.064～1.267,P=0.001)were independent risk factors,while a high level of miR-7-5p(OR=0.090,95％CI:0.033～0.248,P＜0.001)was an independent protective factor for the short-term prognosis of asthmatic children.The area under the ROC curve for miR-7-5p+allergy history+FeNO in predicting the short-term prognosis of asthmatic children was 0.851,which was higher than that for miR-7-5p alone(0.851,Z=2.097,P=0.036)and allergy history+FeNO(0.726,Z=4.239,P＜0.001).The Kappa value for miR-7-5p+allergy history+FeNO was 0.67,which was higher than miR-7-5p(0.44)and allergy history+FeNO(0.41).The MAE for miR-7-5p+allergy history+FeNO was 0.022,which was lower than miR-7-5p alone(0.067)and the combination of allergy history+FeNO(0.035).Conclusion Elevated level of miR-7-5p in the serum exosomes of asthmatic children is linked to a favorable short-term prognosis.The combination of miR-7-5p,allergy history,and FeNO may have certain value in evaluating the short-term prognosis of asthmatic children.
