Efficacy and safety of fecal microbiota transplant for recurrent Clostridium difficile infection in inflammatory bowel disease: a systematic review and meta-analysis

Objectives: the objective of this systematic review and meta-analysis was to evaluate the outcomes of fecal micro -biota transplantation (FMT) therapy for recurrent Clostridium difficile infection (CDI) in inflammatory bowel disease (IBD) patients.Methods: electronic databases were searched for studies reporting on the efficacy and/or safety of FMT therapy for recurrent CDI in IBD. The meta-prop command of the meta package in R was used to assess efficacy and safety. Sub-group analyses were performed to explore heterogeneity regarding all outcomes.Results: eleven trials were included in the study. A pooled analysis showed that the initial cure rate of recurrent CDI among IBD patients was 80 % (95 % CI, 0.76, 0.84), and the overall cure rate after two or more FMT procedures was 90 % (95 % CI, 0.84, 0.94). The recurrence rate post-FMT therapy was 25 % (95 % CI: 0.20, 0.32). Sub-analyses suggested that the initial cure rate of CDI in ulcerative coli-tis (UC) patients was higher than in Crohn's disease (CD) patients (85 % vs. 79 %), with no statistically significant dif-ferences (p > 0.05). No serious adverse events were noted in any of the patients post-FMT.Conclusions: FMT is an effective and safe treatment for recurrent CDI in patients with IBD. FMT should be consid-ered early in cases of recurrent or refractory CDI. Multiple FMT procedures can improve the cure rate of CDI.
