变应性疾病患儿皮肤点刺试验阳性结果的原因分析

Analysis the cause of skin prick positive with allergic disease in children

目的:了解本地区变应性疾病患儿常见变应原的特点,为预防和治疗变应性疾病提供科学依据。方法:1035例进行皮肤点刺患儿吸入变应原有粉尘螨、户尘螨、蒿属花粉、葎草花粉、猫毛、狗毛、蟑螂、酵母;食入变应原有牛奶、鸡蛋清共10种,应用生理盐水和组胺液进行阴性和阳性对照。结果:1035例进行皮肤点刺试验的患儿中吸入性过敏原中尘螨阳性率最高,其中粉尘螨占28.90%,户尘螨占22.92%。变应原阳性反应率与患儿年龄相关,年龄越大阳性反应率越高,其中吸入性过敏原在学龄前儿童表现的比较明显,学龄期后有所降低。结论:呼吸系统变应性疾病通常由过敏原诱发,粉尘螨和户尘螨是最重要的过敏源,它是诱发变应性疾病的重要因素,避免与过敏原接触,可防止变应性疾病的发生并对治疗有指导意义。

Objective：To become common in children with allergic diseases in the regionshould the original features and provide scientific basis for the pre-ventionand treatment of allergic diseases. Methods：1035 cases of skin-prick inhaled allergens in children with original dust mites,house dust mites,pollen-Artemisia,humulus pollen,cat hair,dog hair,cockroaches,yeast;ingestion of allergens original milk,egg a total of 10 species. Application of saline andhista-mine liquid negative and positive controls. Results：1035 cases were skinprick test in children with inhaled dust mite allergens in the highest positiverate, which accounted for 28. 90% of dust mites,house dust mite account for 22. 92%. Allergen positive rate of children with age-related,the higher theage,the greater the positive response rate,which inhalant allergens inpre-school children show more obvious,after school age decreased. Conclusion：Respiratory al-lergic disease is usually induced by the allergens,dust mitesand house dust mite allergy is the most important source,which is an importantfactor in inducing allergic diseases,avoid contact with allergens,allergicdiseases can be prevented The occurrence and treatment guidance.
