目的：探讨青岛地区慢性荨麻疹患者与食物不耐受的相关性。方法：选取慢性荨麻疹患者496 名，采用酶联免疫吸附试验检测血清中14 种食物特异性IgG。结果：385 例患者食物不耐受阳性，以鸡蛋、牛奶、螃蟹、鳕鱼、大豆为主，分别占55.0%、28.6%、 26.8%、19.5%、15.1%；不同年龄组中不耐受的食物所占的比例不同；其中，儿童组：以鸡蛋（84.0%）、牛奶(59.0%)、螃蟹、大豆（16.0%）、鳕鱼（15.3%）为主；青年组：以鸡蛋（55.1%）、牛奶(29.1%)、螃蟹（27.6%）、鳕鱼（22.8%）为主；中年组：以鸡蛋（39.9%）、螃蟹（32.5%）、鳕鱼（18.4%）、大豆(12.9%)为主；老年组：以螃蟹（35.5%）、鸡蛋（27.4%）、大豆(19.4%)、鳕鱼（17.7%）为主。结论：通过检测分析患者血清中特异性IgG，发现青岛及其周边地区慢性荨麻疹患者不耐受的食物以海产品为主，且随年龄增长其敏感性逐渐增加。

英文摘要:

Objective: To investigate the relationship between food intolerance and patients with chronic urticaria in Qingdao. Methods: 14 kinds of food-specific IgG in serum of 496 patients with chronic urticaria were detected by using ELISA assay. Results: There were 385 patients positive for food intolerance, especially eggs, cow's milk, crabs, codfish, soybean which accounted for 55.0℅, 28.6℅,26.8℅,19.5℅,15.1℅, respectively. The proportion varies with age. The kids: with egg (84.0℅), cow's milk (59.0℅), crab and soybean(16.0℅), codfish(15.3℅); The young: with egg(55.1℅), cow's milk(29.1℅), crab(27.6℅), codfish(22.8℅). The middle-aged: with egg(39.9℅), crab(32.5℅), codfish(18.4℅), soybean(12.9℅); The old: with crab(35.5℅), egg(27.4℅), soybean(19.4℅), codfish (17.7℅). Conclusion: Most patients with chronic urticaria in Qingdao could not tolerate marine product, and the sensitivity increased with age.
