摘　　要：目的调查闭塞性细支气管炎(bronchiolitis obliterans,BO)患儿医院感染的相关因素及患儿血清炎性因子指标水平的变化情况。方法选取2012年12月-2016年12月医院收治的BO患儿248例为研究对象,对患儿发生闭塞性细支气管炎的医院感染情况进行统计,分析导致患儿BO医院感染的相关因素,并对感染患儿和未感染患儿的血清炎症因子和T细胞亚群指标进行观察。结果 248例BO患儿发生医院感染58例,感染率为23.39%;年龄、血沉、高热持续时间、胸腔积液、肺部哮鸣音和剧烈咳嗽是BO患儿医院感染的相关因素(P<0.05);感染患儿肿瘤坏死因子-α(TNF-α)、白细胞介素-4(IL-4)、IL-6、IL-8和IL-12分别为(24.11±7.21)ng/L、(96.22±40.11)ng/L、(253.36±50.56)ng/L、(99.23±38.66)ng/L、(134.33±43.77)ng/L血清炎症因子水平均高于未感染患儿(P<0.001);感染患儿CD3+CD4+和CD3+CD8+分别为(410.19±106.84)细胞/μl、(321.20±132.20)细胞/μl低于未感染患儿(P<0.001)。结论小儿BO医院感染应引起临床重视,感染发生与多个因素有关,感染可导致患儿免疫指标降低促炎因子和抗炎因子水平升高,针对上述指标的检测对于感染的监控具有重要的意义。OBJECTIVE To investigate the risk factors of nosocomial infections of children with obstructive bronchiolitis（BO）,and the changes of serum inflammatory factors in children.METHODS A total of 248 children with obstructive bronchiolitis in our hospital from Dec.2012 to Dec.2016 were chosen.The prevalence of nosocomial infections in children with bronchiolitis was taken for statistics.Univariate and multivariate analysis were used to analyze the risk factors of nosocomial infections in children with obstructive bronchiolitis.And the serum inflammatory factors and T cell subsets of infected and non-infected patients were observed and compared.RESULTS Totally 58 cases were of nosocomial infections in the 248 cases of children with occlusive bronchiolitis,and the incidence of nosocomial infections was 23.39%.The age,erythrocyte sedimentation rate,high fever duration,pleural effusion,lung wheeze,and severe cough were the risk factors of nosocomial infections in children with BO（P〈0.05）.The levels of tumor necrosis factor-α（TNF-α）,interleukin-4（IL-4）,interleukin-6（IL-6）,interleukin-8（IL-8）and interleukin-12（IL-12）of children with infection were（24.11±7.21）ng/L,（96.22±40.11）ng/L,（253.36±50.56）ng/L,（99.23±38.66）ng/L and（134.33±43.77）ng/L,which were significantly higher than those of children without infection（P〈0.001）.The CD3＋CD4＋and CD3＋CD8＋of children with infection were（410.19±106.84）cells/μl and（321.20±132.20）cells/μl,which were significantly lower than those of children without infection（P〈0.05）.CONCLUSIONThe nosocomial infection of children with occlusive bronchiolitis should be paid to clinical attention.The occurrence of infection is associated with multiple risk factors,and the infection can lead to a significant decrease of immune indicators and a significant increase of proinflammatory and anti-inflammatory factors of children,so the detection of those indexes has important significance for the monitoring of infection.
