OBJECTIVES: To assess the feasibility and efficacy of fecal microbiota transplantation (FMT) in adolescents (16-21 years) with refractory irritable bowel syndrome (IBS).
METHODS: Randomized controlled pilot trial. Thirty-two patients were included and randomized to receive two allogeneic or autologous FMTs. At baseline and after 6 weeks, two allogeneic or autologous FMTs were administered via a nasoduodenal tube. Feasibility outcomes included dropout rate. Clinical efficacy was evaluated by the proportion of responders (≥50 points reduction in total score of the IBS severity-scoring-system) at 12, 24, and 48 weeks follow-up. Secondary outcomes included health-related quality of life (QoL), depression and anxiety scores, and school/work absenteeism.
RESULTS: One patient (3%) withdrew after randomization, due to lack of effect after the first FMT. Response rates 12 weeks after allogeneic and autologous FMTs were 40% and 38% (p = 0.886). At 24 weeks, significantly more patients responded after allogeneic FMTs (60% vs. 25% autologous, p = 0.048), without significant differences at 48 weeks (60% vs. 50%, p = 0.576). Total QoL score was significantly better after allogeneic than autologous FMTs at 12, 24, and 48 weeks (p = 0.028, p = 0.007, p = 0.011). In the allogeneic FMTs group, school/work absenteeism was 7% at 24 weeks (vs. 41% autologous, p = 0.037).
CONCLUSIONS: Allogeneic FMTs were feasible and resulted in high response rates and better QoL compared to autologous FMTs. These results provide preliminary evidence for the use of allogeneic FMTs in adolescents with refractory IBS.
