762例儿童呼吸系统变态反应性疾病皮肤点刺试验检查结果分析

目的了解成都地区呼吸系统变态反应性疾病儿童常见过敏原分布情况,为预防和治疗儿童呼吸系统变应性疾病提供科学依据。方法应用ALK公司点刺试液进行皮肤点刺试验,同时应用生理盐水和组胺液进行阴性和阳性对照。结果 762例行皮肤点刺试验,447例皮试阳性,皮试阳性率58.7%。螨（粉尘螨、屋尘螨及热带螨）过敏原皮试阳性率明显高于其他过敏原（检验,P〈0.01）。随着年龄增长,呼吸道变态反应性疾病儿童对吸入性变应原更为敏感。哮喘患儿SPT阳性率明显高于非哮喘组患儿。结论儿童呼吸系统变态反应性疾病通常由过敏原诱发,吸入性过敏原为常见过敏原,螨为首要过敏原。过敏原是哮喘发病的重要因素。
