Third-party fecal microbiota transplantation following allo-HCT reconstitutes microbiome diversity

Abstract: We hypothesized that third-party fecal microbiota transplantation (FMT) may restore intestinal microbiome diversity after allogeneic hematopoietic cell transplantation (allo-HCT). In this open-label single-group pilot study, 18 subjects were enrolled before allo-HCT and planned to receive third-party FMT capsules. FMT capsules were administered no later than 4 weeks after neutrophil engraftment, and antibiotics were not allowed within 48 hours before FMT. Five patients did not receive FMT because of the develo… Show more

“…Two cases of adult intestinal toxemia botulism in allogeneic hematopoietic cell transplant recipients have been reported [45,47]. Alteration of the intestinal flora may occur as a result of antibiotics before and during hematopoietic cell transplant, administration of chemotherapy and/or radiation, and altered nutritional patterns [50]. One case has been recorded where the immunosuppressant cyclosporine was administered in the 53 days prior to symptom onset [47].…”

“…(p5) The specific make‐up of the gut microbiota is influenced by numerous factors, including host genotype, age, diet, localized inflammation, antimicrobial use, and direct invasion of pathogenic organisms . In animals and humans, alterations in the gut microbiota have been linked to several important diseases and conditions, including obesity, Crohn's disease, diabetes mellitus, ulcerative colitis, and some forms of neoplasia, making it an important area of current research …”

“…This increase in O 2 may provide a potential mechanistic explanation for changes in microbiome associated with GVHD and IBD. The change in O 2 levels might lead to dysbiosis with loss of microbial diversity, decrease in commensals such as obligate anaerobes and shift towards to aerobes and pathobionts in the microbiome of patients with GVHD and IBD 43 44 45 46 47 48 49 50 51 52 53 54 55 .…”
