Acute Diverticulitis
Conditions
Keywords
probiotic, lactobacillus, colonic diseases, dietary fibre
Brief summary
There is evidence to show that daily probiotic Lactobacillus casei Shirota (LcS) in the form of Yakult fermented milk supports a healthy balanced population of friendly gut bacteria. This, coupled with evidence from four European trials showing probiotic benefit for recurrent diverticulitis and an understanding of how the disease develops, indicates that LcS may also be beneficial. The investigators plan to undertake a pilot study investigating whether consumption of once daily probiotic LcS as Yakult fermented milk would help either prevent attacks of diverticulitis completely or significantly reduce frequency of attacks. Subjects will be recruited from Surrey primary care units and will be closely monitored for 12 months whilst being supplied with a daily dose of for the full 12 months to see if this improves gut health.
Detailed description
Because dietary fibre, obesity and diabetes are all confounding factors that influence the frequency and severity of attacks of diverticulitis, the research project will take account of this by: 1. Monitoring dietary fibre using a diet diary 2. Measurement of height and weight to determine BMI 3. Screening for undiagnosed diabetes and pre-diabetes As well as keeping a diet diary, subjects will be asked to keep a general health diary, and to complete gut health questionnaires at start, 6 months and 12 months.

Inclusion criteria
1. A history of two episodes of UAD treated with antibiotics in the last five years. 2. Diverticulosis confirmed by colonoscopy, barium enema, USS, CT or MRI imaging or at surgery. 3. Agreement to consume one bottle of Yakult daily for 12 months 4. Availability of space in the domestic refrigerator for storage of Yakult units 5. Able to access depot (local primary care premises or chemist) to collect regular supplies of Yakult 6. Able to cope with keeping a diary etc. 7. Willing to take Yakult supplies and a cold bag on holiday to ensure as near as possible continuous daily doses (certainly never more than one week break as Lactobacilli casei will persist in the human gut for at least one week 8.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of episodes of acute diverticulitis | 12 months period of taking daily probiotic | An episode of diverticulitis will be judged as having occured when there is left iliac pain and tenderness judged by the patient's genral practitioner to be due to acute diverticulitis and to be sufficiently severe as to require a course of antibiotics |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gut symptoms assessed by a validated questionnaire at o months, 6 months and 12 months | 12 months | The Bovenschen GIT symptom questionnaire (Bovenschen HJ, Janssen MJR, van Oijen MGH, Laheij RJF, van Rossum LGM, Jansen JBMJ (2006).Evaluation of Gastrolintestinal symptoms questionnaire. Digestive Diseases and Science;51:1509-1515.) will be used to assess this secondary endpoint |
