摘　　要：目的了解重庆地区儿童支气管哮喘急性发作的病原分布特点。方法回顾性分析重庆医科大学附属儿童医院2007年11月至2009年10月收治的203例5岁及以上支气管哮喘急性发作住院患儿临床资料。结果哮喘急性发作患儿肺炎衣原体(CP)检出率为29.6%、肺炎支原体(MP)检出率为22.9%;7种呼吸道病毒检出阳性率为10.2%,其中RSV占4.5%,居病毒检出率首位。哮喘患儿呼吸道感染诱导哮喘的发作窗为(4.2±3.1)d。结论重庆地区5岁及以上儿童哮喘急性发作与呼吸道病毒、MP、CP感染密切相关,且常见的7种呼吸道病毒检出率低。Objective To investigate the distribution of etiological agents in children with asthma exacerbation in Chongqing.Methods Two hundred and three cases of hospitalized children（age ≥ 5 years）with asthma exacerbation from November 2007 to October 2008 in Children＇s Hospital of Chongqing Medical University were retrospectively analyzed.Results Among children with asthma attack,the positive rate of Chlamydia pneumoniae（CP）and Mycoplasma pneumoniae（MP）,was respectively 29.6% and 22.9%;The percentage of 7 common respiratory viruses（including respiratory syncytial virus（RSV）,Adenovirus,Influenza virus A,B,Parainfluenza virus 1,2,3）in children with asthma attack was 10.2%.RSV accounted for 4.5% among patients.The window time of respiratory tract infection-induced asthma attack was primarily determined in 4.2 ± 3.1 days.Conclusions Asthma exacerbation in children is closely related to MP,CP or respiratory viruses infection,but the positive rates of 7 common respiratory tract viruses are low.
