摘要：

目的探讨食物过敏与溃疡性结肠炎的关系。方法用ELISA法检测121例溃疡性结肠炎患者及85例健康对照者的血清食物特异性抗体IgG（sIgG）水平。将血清食物特异性抗体检测阳性的溃疡性结肠炎患者（n=79）随机分为饮食控制组（n=40）和非饮食控制组（n=39）。饮食控制组患者给予常规治疗并忌食IgG阳性食物，非饮食控制组患者仅给予常规治疗，不予饮食干预。随访2个月观察其临床疗效。结果 121例溃疡性结肠炎患者中出现食物sIgG阳性者达79例，阳性率为65.29%。85名健康对照者出现食物sIgG阳性者15例，阳性率为17.65%；两组阳性率比较，差异有统计学意义（P＜0.01）。饮食控制组2个月总有效率达85.0%，非饮食控制组2个月总有效率43.6%，二组比较，差异有统计学意义（P＜0.05）。结论剔除溃疡性结肠炎患者饮食中的IgG阳性食物，有助于提高临床疗效，血清食物特异性抗体IgG水平升高与溃疡性结肠炎发病有关。

Abstract:

Objective To investigate the relationship between ulcerative colitis (UC) and food allergy. Methods The serum food allergen-specific IgG (sIgG) level was detected in 121 patients with ulcerative colitis and 85 health controls by enzymelinked immunosorbent assay (ELISA)． The UC patients who had sIgG-positivity（n=79） were divided into the diet control group（n=40）and the nondiet control group（n=39）. Patients in the diet control group were treated with 5-aminosalicylic acid and prednisone， with their daily diets eliminating the IgG-positive food. Patients in the non-diet control group were treated with 5-aminosalicylic acid and prednisone, without diet restriction. After two months of follow-up, the efficacy in the diet control group and the non-diet control group was observed and compared. Results The sIgG-positive rate in 121 UC patients was 65.29% (79/121), while in the 85 health controls was 17.65%(15/85)． and there was a great statistical significance between the two groups（P＜0.01）． The total response rate in the diet control group was 85.0% during two months of follow-up, while that in the non-diet control group was 43.6%, and there was a significant difference between the two groups (P＜0.05 )． Conclusions Eliminating the IgG-positive food from UC patients′ diet would be helpful to improve the therapeutic efficacy． High level of serum food allergen-specific IgG may be relative to incidence of UC．
