Abstract

By skin prick test, three kinds of mite allergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis) were tested in a group of asthma children in Jinhua area from Oct 2005 to Sep 2006. The positive rate to allergen from D. pteronyssinus and D. farinae was 80.6% and 77.8% respectively, higher than that of Blomia tropicalis (61.1%) (chi2 = 21.39, P < 0.05). Cases positive to Blomia tropicalis allergen showed 100% and 95.9% positive reaction to D. pteronyssinus and D. farinae respectively. The results demonstrated that the important allergens for children's asthma are from D. pteronyssinus and D. farinae, while the with the former two mite allergens. Blomia tropicalis allergen is supposed to have cross-reactivity

摘要

2005年10月至2006年9月，采用皮肤点刺试验对金华地区一组哮喘儿童进行了三种螨类变应原（屋尘螨、粉尘螨、热带无爪螨）检测。屋尘螨和粉尘螨变应原的阳性率分别为80.6%和77.8%，高于热带无爪螨（61.1%）（χ2 = 21.39，P < 0.05）。对热带无爪螨变应原呈阳性反应的病例对屋尘螨和粉尘螨变应原的阳性反应率分别为100%和95.9%。结果表明，儿童哮喘的重要变应原是屋尘螨和粉尘螨，而热带无爪螨变应原与前两种螨类变应原存在交叉反应。
