The lung as a target organ of graft-versus-host disease.
Despite significant advances in critical care and transplantation medicine, non-infectious lung injury remains a major problem following allogeneic hematopoietic stem cell transplantation (HSCT) both in the immediate post-transplant period and in the months to years that follow. Historically, approximately 50% of all pneumonias seen after HSCT have been secondary to infection. Although non-infectious lung injury occasionally occurs following autologous transplants, the allogeneic setting greatly exacerbates toxicity acutely and chronically. Pulmonary injury is associated with significant morbidity and mortality and responds poorly to standard therapies. Insights generated using animal models suggest that the immunologic mechanisms contributing to lung inflammation after HSCT may be similar to those responsible for graft-versus-host disease (GVHD).
