Medical procedure using stool transplants for treating Ulcerative Colitis: Interview with a Specialist
Fecal microbiota transplantation (FMT) is a promising, yet not yet definitive, treatment for ulcerative colitis (UC), a chronic inflammatory bowel disease. The process involves transplanting stool specimens from healthy donors into a patient's gut to recreate a diverse microbiota environment.
While the initial results are encouraging, the current state of research shows that FMT is not a standard treatment for UC. Several small clinical trials and meta-analyses suggest that FMT can approximately double the remission rates compared to controls, particularly in mild-to-moderate UC cases. However, the results vary widely due to differences in trial design, dosing, and delivery methods.
In terms of effectiveness, multiple trials report that about 37% of UC patients receiving FMT achieved remission at 8 weeks compared to about 18% in control groups. However, the evidence supports induction of remission more than maintenance of remission. The optimal patient subsets who benefit most, precise dosing regimens, and long-term treatment strategies remain unclear.
Regarding safety, FMT is generally considered safe, especially when rigorous donor screening is implemented. However, some concerns remain about the rate of serious adverse events, although no conclusive evidence yet shows high risk. Regulatory-approved live biotherapeutic products, like Rebyota, are emerging to standardize safety and quality.
For long-term implications, the potential exists for microbiota-based therapies to become personalized, once biomarkers predicting response and patient subgroups are better identified. The long-term effects and durability of remission after FMT in UC are still largely unknown due to limited follow-up data.
In summary, FMT for UC currently appears safe and moderately effective in inducing remission in some patients. However, more large-scale, standardized, and longer-term studies are required to optimize treatment protocols, confirm long-term safety, and identify which patients benefit the most. Regulatory-approved microbiome therapeutics are advancing the field toward more consistent clinical use.
It is important to note that most people who undergo a fecal transplant for UC do so as part of a research study. The future of fecal transplants as a treatment for UC may involve supplementing other treatment strategies, as researchers continue to have an active interest in studying and regulating the gut microbiota in people with UC.
While the short-term side effects of fecal transplant can include nausea, vomiting, abdominal pain, diarrhea, constipation, flatulence, fever, borborygmus (intestinal rumbling or gurgling), serious side effects are rare but can include severe infection, toxic megacolon, and colon perforation. Fecal transplant can be considered as a treatment option for recurrent Clostridium difficile infection (CDI) that does not respond to first- and second-line therapies.
