Brief Report


Fecal microbiota transplantation (FMT) has emerged as a potential therapy for ulcerative colitis (UC). Several randomized, placebo-controlled trials have shown promise for FMT to induce remission in active UC with lower gastrointestinal administration (colonoscopy/enema) followed by frequent enema maintenance [1]. Clinical remission rates appear higher with maintenance dosing in contrast to a single administration [2, 3]; however, FMT enemas may be burdensome for long-term therapy, and FMT delivered by capsules (cap-FMT) is preferred by patients [4]. Although single-dose administration of cap-FMT is safe for the prevention of recurrent C. difficile infection (rCDI) in those with underlying inflammatory bowel disease (IBD) [5, 6], it is unknown whether frequent maintenance dosing of cap-FMT is safe and well tolerated in UC patients. Accordingly, we aimed to investigate the safety and tolerability of cap-FMT in UC patients as a maintenance regimen following FMT via...
