Predictors factor analysis of acute viral lower respiratory tract infection in children with bronchopulmonary dysplasia / 中国免疫学杂志

ABSTRACT

Objective:To discuss the predictors factor analysis of acute viral lower respiratory tract infection ( AVLRI) in children with bronchopulmonary dysplasia(BPD). Methods:Retrospective survey 60 patients with BPD complicated with AVLRI were selected from June 2015 and June 2017 in our hospital as a combined group,60 children with BPD without AVLRI were selected as control group at the same time,analysis of predictors of AVLRI in children with BPD. Results:In this survey,combined group with respiratory syncytial virus(RSV) infection was the main type of infection,and there were 35 cases(58% ),the result of single factor analysis showed,the incidence of AVLRI in children with BPD was related to factors such as season,feeding mode,family smoking,BPD condition,birth weight,basic diseases,congenital heart disease,maternal gestational diabetes mellitus,atopic diseases and so on(P＜0. 05),the result of Logistics multivariate factor analysis showed,autumn winter season,severe BPD,congenital heart disease,maternal atopic disease,and artificial feeding were predictors of AVLRI in BPD children(P＜0. 05). Conclusion:BPD complicated with AVLRI is often caused by RSV,it is caused by a variety of factors,autumn is the high incidence season,autumn and winter,children with severe BPD, congenital heart disease, maternal atopic disease and artificial feeding may be as a predictor of the occurrence, the effective measures should be taken according to the above factors.
