摘要 目的:探讨儿童常见Ⅰ型变态反应性疾病血清特异性IgE(sIgE)的分布状况,为临床防治提供科学依据。方法:采用瑞典法玛西亚公司的免疫CAP诊断系统,以荧光酶联免疫法测定血清sIgE。结果:198例患儿中可查到152例27种变应原阳性,少数患儿对多种变应原阳性反应。湿疹及特应性皮炎患儿sIgE阳性率为63.3%(38/60);变应性鼻炎患儿sIgE阳性率为48.0%(24/50);支气管哮喘患儿sIgE阳性率为77.3%(68/88)。主要食物性变应原为牛奶、鸡蛋、虾、蟹等,主要吸入性变应原为屋尘螨、粉尘螨、蟑螂、狗毛、猫毛、霉菌等。婴儿组(<1岁)以食物性变应原为主;年长儿童组(>4岁)以吸入性变应原为主。对上述10种变应原的sIgE进行组间比较,经统计学处理后发现吸入性变应原屋尘螨、粉尘螨的sIgE在组间有明显差异,年长儿童组高于婴儿组(P=0.000),食物性变应原的牛奶sIgE在组间有明显差异,年长儿童组高于婴儿组(P=0.000)。结论:上述10种变应原是儿童Ⅰ型变态反应的主要变应原,年龄较小者以食物性变应原为主,随年龄的增长逐步转变为吸入性变应原为主。
