  Background: It is not known if the reduced risk of graft-versus-host disease (GVHD) among patients receiving reduced intensity conditioning (RIC) as opposed to myeloablative conditioning (MAC) is due to differences in mixed donor-recipients chimerism, or to the intensity of the regimen. Methods: We compared patients with acute myeloid leukemia (AML) selected for RIC (n=47) to 46 patients selected for MAC before allogeneic hematopoietic stem cell transplantation (HSCT). Results: Time to neutrophils >0.5 x 109/L was median 15 days in the MAC group, which was faster than 17 days in the RIC group (p=0.001). MAC patients required more erythrocytes (p=0.001) and platelet transfusions (p=0.003). At four weeks, mixed donor-recipient T-cell chimerism was seen in 29% of the MAC patients and 46% of the RIC patients.. Read More»
