Abstract
PURPOSE: The gut microbiota is conceivably a key factor in the aetiology of pouchitis. Faecal microbiota transplantation (FMT) has been suggested as a promising new treatment for chronic pouchitis, where treatment options often are few. However, little is known about the influence of the diet on the clinical effects of FMT. We assessed the diet of patients with chronic pouchitis undergoing FMT to investigate the influence of diet on the clinical outcome after FMT. METHODS: Nine patients with chronic pouchitis were allocated to treatment with FMT delivered by enema from five faecal donors for 14 consecutive days in a 6-month prospective, open-label, single-centre cohort pilot study. A dietary questionnaire was completed at baseline for all patients and donors. Patients underwent a pouchoscopy at baseline and at 30-day follow-up, and the Pouchitis Disease Activity Index (PDAI) was assessed. RESULTS: Patients' diets were generally similar, when comparing patients in remission post-FMT (PDAI < 7) with those who relapsed (PDAI ≥ 7). Consumption of grains trended to be different between the two groups (p = 0.06), where patients in relapse consumed more bread products than did patients in remission. However, consumption of yoghurt was significantly different between the two groups (p = 0.04), with patients in remission consuming more yoghurt (mean 1.1 s/d vs 0.2 s/d). CONCLUSION: Gastroenterologist performing clinical studies on FMT for chronic pouchitis should be aware of dietary habits as contributing factors for the clinical effect of FMT.
