支气管哮喘患儿过敏原检测的结果分析

摘要

目的 分析和探讨支气管哮喘患儿的过敏原分布情况及防护措施.方法 采用免疫印迹法检测348例支气管哮喘患儿特异性IgE和总IgE.结果 吸入性过敏原以屋尘螨/粉尘螨阳性率最高,树花粉次之,食入性过敏原以鸡蛋白/蛋黄阳性率最高,牛奶次之;两组总IgE阳性率无差异性(P>0.05);总吸入性IgE阳性率高于总食入性阳性率(P<0.05);婴儿组吸入性IgE阳性率低于儿童组(P<0.05);婴儿组食入性IgE 阳性率高于儿童组(P<0.05).结论 过敏原是支气管哮喘的诱发因素之一,避免接触过敏原或环境干预降低过敏原的浓度,将减少或避免支气管哮喘的发作次数和减轻症状.%Objective To analyze and explore the distribution of allergen in children with bronchial asthma and its protection measures. Methods The specific IgE and total IgE in 348 cases of children with bronchial asthma were detected by western blotting. Re sults The positive rate of dermatophagoides pteronyssinus was the highest in inhalant allergens, followed by tree and flower pollen. For ingested allergen the highest positive rate was egg white/egg yolk, followed by milk. There was no difference between the total IgE-positive rates of the two groups ( P > 0. 05 ). The total inhalation IgE-positive rate was higher than that of the total ingested positive rate ( P < 0. 05 ). The inhaled IgE-positive rate in the infant group was lower than that of the children group ( P < 0. 05 ), but the infants ingested IgE-positive rate in the infant group was higher than that of the children group ( P < 0. 05 ). Conclusion The allergen is one fart or of bronchial asthma, so it can reduce the paroxysm number of bronchial asthma and alleviate the symptoms by avoiding the contact with aller gens or environmental interventions to reduce allergen concentration.
