Preventive Azithromycin Treatment Reduces Noninfectious Lung Injury and Acute Graft-versus-Host Disease in a Murine Model of Allogeneic Hematopoietic Cell Transplantation

Noninfectious lung injury and acute graft-versus-host disease (GVHD) after allogeneic hematopoietic cell transplantation (allo-HCT) are associated with significant morbidity and mortality. Azithromycin is widely used in allogeneic HCT recipients for pulmonary chronic GVHD, although current data appear controversial. We induced GVHD and noninfectious lung injury in lethally irradiated B6D2F1 mice by transplanting bone marrow and splenic T cells...
