[Efficacy and Safety of Fecal Microbiota Transplantation and Prospect of Microbe-based Therapies for Inflammatory Bowel Disease].

The use of 5-ASA, immunomodulators, biologics, and small molecule drugs are the main treatment for inflammatory bowel disease (IBD), however, fecal microbiota transplantation (FMT) is also drawing attention as a treatment to improve intestinal dysbiosis by transplantaing normal human stool into patients with IBD. FMT demonstrates relatively good effects in inducing clinical remission in IBD, but unlike Clostridium difficile infection, multiple FMT can enhance the clinical effect. There are no reports of the long-term effectiveness and safety of FMT conducted in IBD yet, therefore, well-designed, prospective studies will be needed. Gut microbiota can affect inflammatory response, intestinal barrier function, and host metabolism, so microbe-based therapies are likely to be a new treatment option for IBD. The deeper the understanding of microbe products or effectors, the more likely it is to provide personalized therapy in IBD.
