The investigators hypothesize that perturbations in the intestinal microbiota following allogeneic hematopoietic stem cell transplantation (HSCT) are essential for the development and propagation of acute graft-versus-host disease. Therefore, modification of HSCT recipients' gut microbiota using fecal transplantation from a healthy donor could be used to treat gut acute GVHD. The study evaluates safety and feasibility of fecal microbiota transplantation with frozen capsules from healthy donors for the treatment of steroid resistant or steroid dependent acute graft-versus-host disease of the gut.

RECRUITINGSerious adverse events
Participants will be evaluated for serious adverse events (SAEs) relating to FMT occurring within 28 days following transplantation. SAEs are defined as any adverse experience occurring during or after FMT that results in any of the following outcomes: death, life-threatening experience, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity or an important medical event events
Time frame: 28 days following FMT.
Non-serious adverse events
Participants will be evaluated for non-serious adverse events relating to FMT within 28 days following transplantation. Non-serious adverse events are defined as diarrhea, nausea and vomiting, fatigue and malaise, headache, and distension/bloating/abdominal discomfort/pain
Time frame: 28 days following FMT.
Gut acute Graft-versus-Host Disease (aGvHD) response.
Participants will be evaluated on days 7 and 28 following transplantation for response to therapy. Response criteria for steroid-resistant patients is as follows: * Complete response: resolution of all gastrointestinal signs and symptoms * Partial response: decrease in severity of gut GVHD by at least one stage * Progression: Progressive worsening of gut GVHD * No change: No significant change in gut GVHD Response criteria for steroid-dependent patients is as follows: * Complete response: reduction of the steroid dose to 5 mg or less of prednisone (or a steroid equivalent) per day. * Partial response: a reduction of ≥40% in the dose of steroid * Progression: an increase of \>=10% in the steroid dose * No change: any other option
Time frame: up to 28 days following FMT.
aGvHD severity
Participants will be evaluated on days 7 and 28 following transplantation for severity of aGvHD. aGVHD severity is graded by the International Bone Marrow Transplant Registry Severity Index grading system
Time frame: up to 28 days following FMT.
Reduction in the dose of steroids.
The dose of methylprednisolone, or an equivalent GCS, will be evaluated on day 7, and 28. The change in the dose at day 28, adjusted to the type of GCS used.
Time frame: up to 28 days following FMT.
