Study Summary

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. UC pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts.

The purpose of this study is to determine the effect of the fecal microbiota transplantation on UC.

Study Description

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease affecting approximately 90 000 patients in France, mostly at young age, and altering their quality of life.

Conventional Immunosuppressive treatment (ie azathioprine, anti-TNF (tumor necrosis factor ), vedolizumab) used in UC are expensive and associated with potentially severe complications such as infections and cancers.

UC pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts.

Fecal microbiota transplantation (FMT) is now recommended in guidelines for treating recurrent Clostridium difficile infection. Although the pathogenesis involved in UC is different, FMT is a potential therapeutic strategy as transferring a healthy microbiota in an UC patient could restore the appropriate host-microbiota crosstalk.

As the gut microbiota is dramatically altered by intestinal inflammation, transferring a massive amount of microbial organisms in an inflamed gut with epithelial barrier disruption might be a suboptimal strategy and could even have detrimental effects by allowing bacterial translocation.

Thus, it's possible that performing FMT in UC patients who achieved remission after conventional treatment might be associated with better clinical outcome than in patients with active disease.
