[摘要] 目的 探讨过敏性紫癜患儿血清过敏原特异性IgE检测的临床意义。方法 采用德国敏筛过敏原定量检测系统,检测150例过敏性紫癜患儿的血清过敏原特异性IgE和总IgE水平。结果 150例患儿的血清总IgE阳性率为92%,其中食物性过敏原特异性IgE阳性率明显高于吸入性过敏原特异性IgE阳性率。吸入性过敏原中尘粉螨阳性率最高,食物性过敏原中虾蟹阳性率最高。结论 过敏性紫癜的发生与多种过敏原有一定的相关性,并且以食物性过敏原触发为主,血清过敏原特异性IgE检测对过敏性紫癜的病因诊断和预防有参考意义。

[Abstract] Objective To study the clinical significance of allergen-specific IgE detection of anaphylactoid purpura in children. Methods The German sensitive quantitative detection of allergen screening system to detect 150 cases of anaphylactoid purpura in children with serum allergen-specific IgE and total IgE levels. Results One hundred fifty patients with serum total IgE in children with positive rate was 92%,of which food allergen-specific IgE-positive rate than inhaled allergen-specific IgE-positive rate was significantly higher ......
