作者给变异型哮喘患者(74例)和经典型哮喘(115例,哮喘严重程度不等)检测7种常见气传性变应原的特异性IgE。咳嗽变异型哮喘定义为咳嗽,无喘鸣或呼吸困难,乙酰甲胆碱激发试验证实有气道高反应性,支气管扩张剂治疗后症状改善。与咳嗽变异型哮喘组相比,经典型哮喘组患者总IgE水平较高(P<0.0001);对更多的变应原敏感(P=0.03);狗皮屑变态反应率较高(分别为24%和3%,P<0.0001);室内尘螨变态反
The authors tested specific IgE for seven common air-borne allergens in patients with variant asthma (n = 74) and classic asthma (n = 115 with varying degrees of asthma severity). Cough variant asthma is defined as cough, no wheezing, or dyspnea, methacholine provocation test has confirmed airway hyperresponsiveness, and bronchodilator symptoms improved after treatment. Patients with classical asthma had a higher total IgE level (P <0.0001), more allergens (P = 0.03), and a higher rate of dandruff allergy (24 % And 3%, P <0.0001); house dust mite allergy
