Brief Summary

The aim of this study is to assess the Fecal Microbiota Transplantation (FMT) efficacy in the prevention of allogeneic hematopoietic stem cell transplantation (allo-HSCT) complications and particularly Graft versus Host Disease (GvHD). The hypothesis of this study is that allogeneic FMT may improve outcomes of these patients.
