摘要 目的探讨急性哮喘患儿体内Th细胞亚群及血清IgE的变化。方法随机选择急性哮喘发作期哮喘患儿52例,通过测定血清IFN-γ、IL-4,来了解外周血从中测定Th细胞亚群,并与20名非哮喘儿童的结果进行对比。结果哮喘发作组外周血中Th1为7.2%,Th2为4.3%,Th2/Th1比值为:16.43,IgE为859IU/L。非哮喘儿童组Th1为18.5%,Th2为1.2%,Th2/Th1比值为:12.50,IgE为:130IU/L。哮喘急性发作组与非哮喘组对比,以上数据差异均有显著性(P<0.01)。结论哮喘患儿急性发作期Th亚群存在明显失衡,Th2/Th1比值失衡提示辅助性T细胞免疫在哮喘急性发作中具有重要作用、IgE增高提示哮喘是一种由IgE介导的I型变态反应,在有条件的医院做此项检查,有利于检测哮喘的病情及免疫水平,指导临床进行病情评估。
