About

Patients who have a gastrointestinal acute Graft versus host disease (GVHD) received a first-line standard treatment of corticosteroids. For patients who do not respond or progress after an initial response have a high mortality. There is an interest in identifying effective second line therapy for these patients corticosteroid-resistant acute GVHD. Fecal microbiota transfer might be a beneficial treatment in this clinical situation with a poor prognosis and limited therapeutic options.
