Faecal microbiota transplantation (FMT) is beneficial in patients with active ulcerative colitis (UC), but its role in the maintenance of clinical remission and mucosal healing has not been assessed.Methods
This was a prospective, double-blind, randomised placebo-controlled trial conducted at Dayanand Medical College and Hospital, India. Twenty-eight patients with UC in clinical remission (Mayo Score=1) and histological remission (Nancy grade 0, 1) at 48 weeks.Results
Twenty-eight patients (50% males, aged 37.21±15.25 years) with UC in clinical remission were randomised to groups A and B. At the end of 48 weeks, none of the patients in either group suffered a clinical relapse (p=1). Deep remission was noted in significantly higher number of patients with FMT (n=12, 85.71%) when compared with placebo (n=4, 28.57%) (p=0.002). Histological remission was twice as high in patients treated with FMT (n=8, 57.14% vs placebo, n=4, 28.57%; p=0.13). Rate of endoscopic response was also higher with FMT (n=8, 57.14%) when compared to placebo (n=0, zero%) (p=0.001). No serious adverse events were noted.Conclusions
Maintenance with FMT can enhance achievement of deep remission and histological remission in patients with UC in clinical remission.
