Background and study aims
Irritable bowel syndrome (IBS) is a common condition which causes symptoms of abdominal pain, bloating and altered bowel habits. Conventional treatment is frequently unsatisfactory. The cause of IBS is unknown, but it has been suggested that many of the symptoms result from undigested carbohydrates reaching the large bowel (colon). When this happens the gut bacteria living in the large bowel can ferment undigested food, producing chemicals that cause IBS. These chemicals can be detected in both blood and urine. It has been shown that reducing the number of certain carbohydrates in the diet can improve the symptoms of IBS for some patients. The aim of this study is to find out whether giving a food supplement called enzyme rich malt extract (ERME), which contains a high concentration of enzymes that digest carbohydrates, will improve symptoms of IBS. ERME is a by-product of the malting process, in which cereal grains (like barley) are dried, commonly for making beer. It is sweet, palatable and has been used as an ingredient in baking and cookery for many years.
Who can participate?
Patients aged 18-65 with IBS
What does the study involve?
Participants are randomly allocated to take 30 ml of either ERME or an inactive malt product every day for 6 weeks. Participants are followed up by telephone at 2-week intervals until 8 weeks. At week 6 there is a follow-up clinic visit to measure IBS severity using a questionnaire.

| Scientific title | Double blind randomised controlled trial comparing the effect of enzyme rich malt extract with placebo in the treatment of irritable bowel syndrome |
| Study objectives | There will be a difference in IBS severity score at 6-weeks post randomisation between the two groups. |
| Ethics approval(s) | North of Scotland Research Ethics Service, 17/08/2017, REC ref: 17/NS/0079 |
| Health condition(s) or problem(s) studied | Irritable Bowel Disease |
| Intervention | Participants will be randomised 1:1 to either ERME (enzyme rich malt extract) or control (heat denatured malt product). Participants will be asked to consume 30 ml per day for 6 weeks. Participants will be followed up at 2-week intervals until 8 weeks. At week 6 the follow-up visit will consist of a clinic visit all others will be over the telephone. |
| Intervention type | Supplement |
| Primary outcome measure | IBS severity is measured using the IBS Severity Score Questionnaire at 6 weeks |
| Secondary outcome measures | 1. Severity of abdominal pain is measured using IBS Severity Score Questionnaire at baseline, 2,4, 6 and 8 weeks 2. Frequency of abdominal pain is measured using IBS Severity Score Questionnaire at baseline, 2,4, 6 and 8 weeks 3. Abdominal bloating measured using IBS Severity Score Questionnaire at baseline, 2,4, 6 and 8 weeks 4. Bowel habit “satisfaction” is measured using IBS QoL Questionnaire at baseline 2,4, 6 and 8 weeks 5. impact of IBS upon lifestyle is measured using IBS QoL Questionnaire at baseline, 2,4, 6 and 8 weeks 6. Bowel frequency is measured using self-report by participants at baseline and 6 weeks 7. Stool Consistency is measured using Bristol Stool Chart at baseline and 6 weeks 8. Absence from work days related to IBS is measured using IBS Severity score scales at baseline , 2,4, 6 and 8 weeks 9. IBS quality of life is measured using IBS QoL Questionnaire Score at baseline , 2,4, 6 and 8 weeks |
