Fecal microbiota transplantation for refractory chronic graft-versus-host disease after allogeneic hematopoietic cell transplantation: a pilot open-label, non-placebo-controlled study.

ABSTRACT:

Background

Dysbiosis of the intestinal microbiota plays a crucial role in the initiation and development of graft-versus-host disease (GVHD). Fecal microbiota transplantation (FMT) has been reported to be effective for refractory acute GVHD; however, whether FMT is effective for refractory chronic GVHD (cGVHD) remains unknown.

Methods

To investigate the efficacy and safety of FMT for refractory cGVHD and the underlying mechanism, 12 patients with refractory cGVHD received FMT via colonoscopy, and the response was evaluated at 12 weeks after FMT.

Results

Among the 12 patients who underwent FMT, 1 patient achieved a complete response, and 5 patients achieved a partial response. Patients with refractory cGVHD presented lower α diversity and higher abundance of Escherichi
