哮喘及过敏素质儿童的EIA效应初探

STUDY OF EXERCISED-INDUCED ASTHMA(EIA)TEST ON ASTHMA AND AToPIC STATUS IN cHILDREN

在室温１６士２℃下，对３７例哮喘、３２例过敏素质的无哮喘儿和４５例健康儿进行了运动激发哮喘试验（Ｅｘｅｒｃｉｓｅ－ｉｎｄｕｃｅｄａｓｔｈｍａＥＩＡ），结果显示ＥＩＡ阳性率分别为４５．９％、１５．６％和８．９％，三组间差异有非常显著性意义（Ｐ＜０．０１），过敏组与健康组之间差异无显著性意义（Ｐ＞０．０５），而过敏组与哮喘组之间差异有非常显著性意义（Ｐ＜０．０１），提示过敏与气道高反应性无密切相关，在哮喘的诊断上气道高反应性的意义远比过敏重要，加强对无症状的ＥＩＡ患者的监测，对早期诊断哮喘和改善其预后可能具有重要的意义。

xercised-induced asthma(EIA)test was studied in 37 asthma,32 stopic status and 45 con-trol cases.The results showed that positive rates of EIA were 45.9%,16.1%and 8.9%respec-tively.There was significant difference among three groups(P<0.01).The atopic group did notdiffer from controls(P>0.05)but from asthmatic group(P<0.0l).These findings suggestedthat there was no close relationship between the atopic status and the airway hyperreactivity.Ondiagnosis of asthma,the significance of airway hyperreactivity was more important than that ofatopic status.To strengthen the inonitor of the asymptomatic EIA patient,it might be of impor-tant significance to diagnose asthma early and improve the prognosis.
