170例小儿常见过敏原分析

Detection and analysis on common allergens in 170 children

目的探讨食物性及吸入性过敏原在小儿常见过敏性疾病中的意义。方法采用酶免疫分析法对170例患儿进行血清特异性免疫球蛋白E检测。结果170例患者中有150例在全部14项过敏原中至少1项出现阳性反应,总阳性率为88.0%;在吸入性过敏原中以尘螨和粉螨阳性率最高(54.7%)。在食物组中,以牛肉、羊肉、鸡肉的阳性率最高(20.6%)。结论通过血清过敏原检测找出引起病症的过敏原(吸入性和食物性),指导患儿减少对变应原的暴露,对更有效地解决过敏患者的病痛有着极其重要的意义。

Objective To explore the clinical significance of food allergen and inhaled allergen in common aller gic diseases in children. Methods Enzyme immunoassay（EIA） was applied to examining serum specific IgE in 170 children patients. Results Positive judgement standard： reactive to at least 1 kind in 14 kinds of allergens. The posi tive rate was 88.0 % （150/170）. In positive inhaled allergens, dust mite and flour mite were predominant（54.7 % ） ; in positive food allergens,beef,mutton and chicken were prominent（20.6 %）. Conclusion It is vital to alleviation of indisposition in autopaths to search for positive food allergen or inhaled allergen by serum allergen detection, and reduce exposure to allergens.
