Abstract

BACKGROUND AND AIMS: To investigate if treatment with non-pooled multi-donor faecal microbiota transplantation (FMT) for four weeks was superior to placebo to induce clinical remission in patients with chronic pouchitis.

METHODS: The study was a randomised double-blinded placebo-controlled study with a 4-week intervention period and 12-month follow-up. Eligible patients with chronic pouchitis were recruited from five Danish hospitals. Participants were randomised to non-pooled multi-donor FMT derived from four faecal donors, or placebo. Treatment was delivered daily by enema for two weeks followed by every second day for two weeks. Disease severity was accessed at inclusion and 30-day follow-up, using the Pouchitis Disease Activity Index (PDAI); PDAI <7 was considered equivalent to clinical remission. Faecal samples from participants and donors were analysed by shotgun metagenomic sequencing.

RESULTS: Inclusion was stopped after inclusion of 30 participants who were randomised 1:1 for treatment with FMT or placebo. There was no difference in participants achieving clinical remission between the two groups at 30-day follow-up, relative risk 1.0 (95%CI(0.55;1.81)). Treatment with FMT resulted in a clinically relevant increase in adverse events compared to placebo, incidence rate ratio 1.67 (95%CI(1.10;2.52)); no serious adverse events within either group. Faecal microbiota transplantation statistically significantly increased the similarity of participant faecal microbiome to the faecal donor microbiome at 30-days follow-up (p=0.01), which was not seen after placebo.

CONCLUSIONS: Non-pooled multi-donor FMT was comparable to placebo in inducing clinical remission in patients with chronic pouchitis but showed a clinically relevant increase in adverse events compared to placebo.
