摘要
目的:了解病毒感染与儿童哮喘急性发作之间的相关性。方法:应用直接免疫荧光法(DIF),对实验组(367例哮喘急性发作患儿)和对照组(403例哮喘缓解期患儿)鼻咽分泌物进行7种病毒抗原检测。结果:实验组239例检出至少1种病毒,总检出率65.1%。呼吸道合胞病毒(RSV)检出最多,为154例,检出率42.0%,其余,依次为副流感病毒Ⅲ(PIVⅢ)31例(8.4%),腺病毒(ADV)25例(6.8%),流感病毒A(IFA)11例(3.0%),流感病毒B(IFB)9例(2.5%),副流感病毒Ⅰ(PIVⅠ)5例(1.4%),副流感病毒Ⅱ(PIVⅡ)4例(1.1%)。6个月以下年龄组阳性率最高,为67.5%。RSV季节性较明显,主要集中在冬春季节(10月至次年4月)。对照组60例检出至少1种病毒,总检出率14.9%。呼吸道合胞病毒(RSV)检出最多,为39例,检出率9.7%,其余,依次为副流感病毒Ⅲ(PIVⅢ)11例(2.7%),腺病毒(ADV)5例(1.2%),流感病毒A(IFA)3例(0.7%),流感病毒B(IFB)1例(0.2%),副流感病毒Ⅰ(PIVⅠ)1例(0.2%),副流感病毒Ⅱ(PIVⅡ)0例(0%)。两组比较差异有显著性意义(P<0.01)。结论:病毒感染与儿童哮喘急性发作有密切相关性,RSV是引起婴幼儿哮喘急性发作的主要病毒,主要集中在冬春季节。
Objective：To explore the correlation analysis between virus infection and acute asthmatic attack in children.Methods：Totally seven-hundred seventy children with asthma were recruited,and divided into experimental group（n=367）with acute asthmatic attack and control group（n=403）with asthma in remission stage.Seven virus infections were identified by immunofluorescence testing of nasopharyngeal swabs was collected during respiratory episodes.Results：There are at least one virus was detected in experimental group（239/367,65.1%）and control group（60/403,14.9%）.Respiratory syncytial virus（RSV）was the most（154/367,42.0%in experimental group and 39/403,9.7%in control group）,and the others were parainfluenzaⅢ（31/367,8.4% and 11/403,2.7%,respectively）,adenovirus（25/367,6.8% and 5/403,1.2%,respectively）,influenza A virus（11/367,3.0% and 3/403,0.7%,respectively）,influenza B virus（9/367,2.5%and 1/403,0.2%,respectively）,parainfluenzaⅠ（5/367,1.4%and 1/403,0.2%,respectively）,parainfluenzaⅡ（4/367,1.1% and 0/403,0%,respectively）.It is significantly difference between experimental group and control group（P〈0.01）.The detection rates of virus was highest in children aged〈6month（67.5%）.RSV infection has obvious seasonal character,most illness occurs in yearly outbreak in the winter and early spring months,e.g.October to April.Conclusion：There is a close relationship between virus infection and acute asthmatic attack in children.RSV is the major causes of acute asthmatic attack in infant,and the peak of onset was in winter and spring.
