Fecal Microbiota Transplantation for Steroid-Refractory Acute GI GVHD

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective treatment for various hematologic diseases. However, one of the major challenges of allo-HSCT is the occurrence of graft-versus-host disease (GvHD), particularly acute gastrointestinal GvHD (GI-GvHD). GvHD occurs when donor T cells recognize the recipient's tissue as foreign and mount an immune attack against it. Acute GI-GvHD is a common complication following allo-HSCT and a significant cause of mortality. If the initial steroid treatment for acute GvHD fails, mortality rates can reach as high as 81%. Recent studies have shown a strong association between reduced gut microbiota diversity and high mortality in patients with acute GI-GvHD, highlighting the critical role of the gut microbiome in regulating immune responses and maintaining intestinal homeostasis. Consequently, fecal microbiota transplantation (FMT) has emerged as a potential therapeutic strategy aimed at restoring a healthy gut microbiome and improving clinical outcomes in patients with acute GI-GvHD. This study aims to evaluate the efficacy and safety of FMT in patients with steroid-refractory or steroid-resistant acute GI-GvHD. The findings of this research will contribute to establishing FMT as a potential and effective treatment option for managing severe acute GI-GvHD, thereby improving patient outcomes and reducing transplant-related mortality.
