Rational Modification of Human Gut Microbial Metabolites by Dietary Resistant Starch in Patients After Allogeneic Hematopoietic Stem Cell Transplantation: A Prospective Feasibility Study

We conducted a prospective longitudinal feasibility study in patients undergoing allo-HCT for hematological malignancies to test the hypothesis that defined and consistent administration of resistant starch will rationally modify intestinal microbiota dependent metabolites, particularly the short chain fatty acids (SCFA), such as butyrate. Ten adults undergoing human leukocyte antigen-matched, related-donor myeloablative allo-HCT were enrolled and received resistant potato starch (RPS) daily from day -7 to day 100 after allo-HCT.
