These included two cases of sepsis secondary to bacteremia caused by Veillonella Parvula and Escherichia Coli (3 and 10 days after FMT respectively); one case of endocarditis due to Staphylococcus aureus meticilino-sensible (5 days after FMT) in a patient with aortic prosthesis, a reactivation of Cytomegalovirus detected in a seropositive patient (day 30 of FMT) and one case of pneumonia (7 days after FMT) (Figure 1). To preserve the new intestinal flora, large spectrum antibiotics were only used when vital prognosis was engaged. Otherwise, none of the patients developed fungal infection during the follow up. As late gastro-intestinal complications, we noted the occurrence of a fatal occlusive syndrome and hematochezia in two patients on day 38 and 45 respectively. Cardio-vascular complications were also present, including pulmonary embolism causing death in the patient with aortic prothesis.

Actually, the patient alive has normal stool frequency and consistency with reduction of abdominal cramps, corticosteroids and immunosuppressive medication were discontinued after a progressive tapering and close supervision. Summary/Conclusion: Fecal microbiota transplantation is becoming a growing therapy in SR GI-GvHD, the evolution of patients appears favorable and largely free of severe adverse events. However, recipients should be well aware of its potential risks. HemaSphere | 2023;7(S3) EHA2023 Hybrid Congress Copyright Information: (Online) ISSN: 2572-9241 © 2023 the Author(s).
