Abstract:
Objective To investigate the effect of eosinophil(EOS)/neutrophil(NER)in peripheral blood on asthma recurrence in children with bronchial asthma(BA)after treatment.Methods A prospective cohort study was conducted in the study.BA children admitted to the hospital from February 2020 to February 2022 were selected as the research objects.All children were treated regularly and their condition was under con-trol.After a follow-up of 6 months,the recurrence of the children was recorded.EOS/NER,interleukin(IL)-4 and IL-5 of children with and without relapse before treatment and at 1 week of treatment were compared.Lo-gistic regression analysis model was established to test the effect of EOS/NER on the recurrence of asthma in children with BA after treatment.The receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of EOS/NER,IL-4 and IL-5 before treatment for the recurrence risk of BA children after treatment.Results A total of 128 children with BA were included.25 cases recurred after 6 months of follow-up,with a recurrence rate of 19.53%.EOS/NER,IL-4 and IL-5 of BA children after 1 week of treatment were lower than those before treatment(P<0.05).EOS/NER,IL-4 and IL-5 of recurrent children before treat-ment and 1 week after treatment were higher than those of non-recurrent children(P<0.05).There were no statistically significant differences in EOS/NER,IL-4,IL-5 levels between children of different genders,age groups,and treatment regimens before and after 1 week of treatment(P>0.05).Increased EOS/NER,in-creased level of IL-4 and increased level of IL-5 had effect on the recurrence of BA children after treatment and may be risk factors for recurrence(OR>1,P<0.05).The ROC curve showed that area under the curve of EOS/NER before treatment for predicting the recurrence was 0.810(95%CI:0.724-0.896,P<0.001)in BA patients after 6 months of treatment,with moderate predictive value.Conclusion EOS/NER before treat-ment in BA children may be an independent risk factor for recurrence after treatment,and has moderate pre-dictive value for recurrence risk.
