Cyclosporin A is associated with faster engraftment and less mucositis than methotrexate after allogeneic bone marrow transplantation

Abstract
Summary. Thirty‐eight patients with severe aplastic anaemia or acute leukaemia received HLA‐identical sibling marrow transplants. Seventeen were treated with methotrexate and 21 with cyclosporin A (CyA) to minimize graft‐versus‐host disease post transplant. Marrow engraftment was more rapid and oropharyngeal mucositis less severe in those receiving CyA. This resulted in a shorter period of neutropenia and thrombocytopenia, fewer platelet and granulocyte transfusions and less fever. These benefits have to be weighed against the increased nephrotoxicity of CyA.
