[摘要] 目的 探讨成都地区特应性皮炎患儿常见过敏原血清特异性IgE情况及随年龄增长的变化。 方法 方便选取该院儿童皮肤科门诊2013年9月—2016年8月就诊的AD患儿424例，采用免疫印迹法体外半定量检查特应性皮炎患儿血清IgE的抗体。 结果 424例特应性皮炎患儿中，阳性患儿268例。阳性率为63.81%。6月～1岁组阳性率为66.96%。1～3岁组阳性率为66.02%，3～12岁组阳性率为51.54% 。424例特应性IgE抗体阳性率及积分由高到低(前5位)为鸡蛋白、牛奶、屋尘、屋尘螨/粉尘螨、虾。6个月～1岁组与3～12岁组最常见过敏原是鸡蛋白及牛奶，3～12岁组最常见过敏原是屋尘、屋尘螨/粉尘螨。 结论 12岁以下特应性皮炎的常见过敏原为鸡蛋白、牛奶、屋尘、屋尘螨/粉尘螨，但不同年龄组最常见过敏原不尽相同。
