天津地区食物过敏患者sIgG检测结果分析

目的:了解天津地区过敏患者血清食物过敏原特异性IgG(sIgG)的表达情况,探讨食物不耐受与过敏性皮肤病的关系。方法:应用酶联免疫吸附试验(ELISA)对834例疑似食物变态反应性疾病患者血清中食物过敏原的sIgG抗体进行检测,分析食物过敏原种类特点。结果:834例患者中有638例有1~11种不等的食物过敏原sIgG升高,总阳性率为76.5%,其中存在1~2种食物不耐受的比例最高(58.1%)。在14种食物中,食物过敏原sIgG升高以鸡蛋(51.9%)最多见,其次分别是蟹(21.6%)、虾(19.3%)、牛奶(16.5%),猪肉sIgG阳性率(0.5%)最低。另外,≤14岁患者与>14岁患者对鸡蛋、牛奶、蟹、虾、小麦、西红柿过敏情况差异有统计学意义(均P<0.01)。241例皮肤病患者中有171例食物过敏原检测结果呈阳性,阳性反应率为71.0%。结论:鸡蛋、甲壳类(蟹、虾)、牛奶是食物变态反应性疾病的主要过敏原。食物过敏或食物不耐受的症状与皮肤过敏性疾病关系密切。

Analysis of sIgG Detection in Patients with Food Allergy in Tianjin Area

Objective:To investigate the relationship between food intolerance and allergenic dermatosis by detecting the serum level of food allergen specific IgG(sIgG) in allergic patients.Methods:Enzyme linked immunosorbent assay(ELISA) was used to detect sIgG in 834 patients suspected food hypersensitivity disease of Tianjin area.The characteristics of kinds of food allergens were analyzed.Results:There were increased food allergen sIgG(1 or more,up to 11 kinds) in 638 patients of 834,and the total positive rate wa...
