Gut microbiota predict pulmonary infiltrates after allogeneic hematopoietic cell transplantation
Hematopoietic Stem Cell Transplantation
This is the first study to demonstrate prospective changes in gut microbiota associated with PCs after HCT. Postengraftment PCs and γ-proteobacteria domination were predictive of mortality. This suggests an adverse relationship between the graft and lung, which is perhaps mediated by bacterial composition in the gut. Further study is warranted.
