Longitudinal Analysis of Gut Bacteriome, Mycobiome, Virome and Metabolome in Allogeneic Stem Cell Transplantation Reveals Susceptibility for Acute Graft-Versus-Host Disease

The intestinal microbiome directly effects outcomes in patients undergoing allogeneic stem cell transplantation (ASCT) (Peled et al., N Engl J Med, 2020). Recent developments in microbiome research allow us to look beyond bacterial communities at the composition of the intestinal mycobiome and virome. However, only few studies have addressed these fungal (Zhang et al., Nat Commun, 2021; Legoff et al., Nat Med, 2017) and viral communities (Van Der Velden et al., Biol Blood Marrow Transplant, 2013) in the ASCT setting.
