ABSTRACT
Various reduced-intensity conditioning regimens are in use for allogeneic hematopoietic cell transplant (HSCT) in patients with idiopathic severe aplastic anemia (SAA). We describe the use of fludarabine, Campath, and low-dose cyclophosphamide (FCClow) conditioning in 15 children undergoing related or unrelated donor transplants. Total body irradiation (TBI) of 2 Gy was added for unrelated donor HSCT. At a median follow-up of 2.3 years, the failure-free survival was 100%, with low rates of infection and toxicity. There was no occurrence of grade III to IV acute graft-versus-host disease (GVHD). All patients had full donor myeloid chimerism post-HSCT, even with mixed chimerism in the T cell lineage. The absence of chronic GVHD and long-term stable mixed donor T cell chimerism confirms immune tolerance following FCClow (± TBI) conditioned transplantation in children with SAA.
