Using Fecal Microbiota Transplantation and Fiber to Treat Graft-versus-host Disease After Stem Cell Transplants

Fecal Microbiota Transplantation and Fiber for the Treatment of Graft-versus-host Disease After Hematopoietic Cell Transplantation

NIH-funded research Fred Hutchinson Cancer Center · NIH-11137074

What this research studies

After a stem cell transplant, many patients experience graft-versus-host disease (GvHD), a serious complication where the new immune cells attack the patient's body. We know that changes in gut bacteria are linked to GvHD, and earlier observations suggest that replacing gut bacteria through fecal microbiota transplantation (FMT) could be helpful. This project aims to understand how different ways of delivering FMT, like oral capsules, affect the gut bacteria and whether adding dietary fiber can help maintain a healthy gut environment. We also want to learn more about how these changes in gut bacteria might improve patient outcomes.

Who could benefit from this research

Good fit: Ideal candidates for this type of research would be patients who have undergone an allogeneic hematopoietic cell transplantation and are experiencing graft-versus-host disease.

Not a fit: Patients who have not received an allogeneic hematopoietic cell transplantation or are not experiencing graft-versus-host disease would not directly benefit from this specific treatment approach.

Why it matters

Potential benefit: If successful, this approach could offer a new and effective way to treat graft-versus-host disease, improving recovery and quality of life for patients after stem cell transplantation.

How similar studies have performed: Observational studies have shown promising results for fecal microbiota transplantation in repopulating gut bacteria in stem cell transplant recipients with GvHD, suggesting this is a promising, though still developing, area.
