Abstract

AIM

To investigate the effect of a low-FODMAP diet on irritable bowel syndrome (IBS)-like symptoms in patients with inflammatory bowel disease (IBD).

METHODS

This was a randomised controlled open-label trial of patients with IBD in remission or with mild-to-moderate disease and coexisting IBS-like symptoms (Rome III) randomly assigned to a Low-FODMAP diet (LFD) or a normal diet (ND) for 6 wk between June 2012 and December 2013. Patients completed the IBS symptom severity system (IBS-SSS) and short IBD quality of life questionnaire (SIBDQ) at weeks 0 and 6. The primary end-point was response rates (at least 50-point reduction) in IBS-SSS at week 6 between groups; secondary end-point was the impact on quality of life.

RESULTS

Eighty-nine patients, 67 (75%) women, median age 40, range 20-70 years were randomised: 44 to LFD group and 45 to ND, from which 78 patients completed the study period and were included in the final analysis (37 LFD and 41 ND). There was a significantly larger proportion of responders in the LFD group ( = 30, 81%) than in the ND group ( = 19, 46%); (OR = 5.30; 95%CI: 1.81-15.55, < 0.01). At week 6, the LFD group showed a significantly lower median IBS-SSS (median 115; inter-quartile range [IQR] 33-169) than ND group (median 170, IQR 91-288), = 0.02. Furthermore, the LFD group had a significantly greater increase in SIBDQ (median 60, IQR 51-65) than the ND group (median 50, IQR 39-60), < 0.01.

CONCLUSION

In a prospective study, a low-FODMAP diet reduced IBS-like symptoms and increased quality of life in patients with IBD in remission.

摘要

目的

探讨低发酵性寡糖、双糖、单糖和多元醇（FODMAP）饮食对炎症性肠病（IBD）患者肠易激综合征（IBS）样症状的影响。

方法

这是一项随机对照开放标签试验，研究对象为病情缓解或轻度至中度的IBD患者且伴有IBS样症状（罗马III标准），于2012年6月至2013年12月期间随机分为低FODMAP饮食（LFD）组或正常饮食（ND）组，为期6周。患者在第0周和第6周完成IBS症状严重程度系统（IBS-SSS）和简短IBD生活质量问卷（SIBDQ）。主要终点是两组在第6周时IBS-SSS的缓解率（至少降低50分）；次要终点是对生活质量的影响。

结果

89例患者，67例（75%）为女性，中位年龄40岁，年龄范围20 - 70岁，被随机分组：44例进入LFD组，45例进入ND组，其中78例患者完成研究期并纳入最终分析（37例LFD组和41例ND组）。LFD组缓解者比例（n = 30，81%）显著高于ND组（n = 19，46%）；（优势比[OR] = 5.30；95%置信区间[CI]：1.81 - 15.55，P < 0.01）。在第6周时，LFD组的IBS-SSS中位数（中位数115；四分位间距[IQR] 33 - 169）显著低于ND组（中位数170，IQR 91 - 288），P = 0.02。此外，LFD组的SIBDQ增加幅度（中位数60，IQR 51 - 65）显著大于ND组（中位数50，IQR 39 - 60），P < 0.01。
