title: Iron overload and liver dysfunction after allogeneic or autologous bone marrow transplantation.
abstract: Patients who require a bone marrow transplant (BMT) for leukaemia, lymphoma or other haematological disorders receive large quantities of blood products, including red cell concentrates, during the transplant period. Many receive red cell transfusions as part of treatment prior to BMT, adding to the potential iron load. However, organ dysfunction as a consequence of the transfused iron load would be surprising given the amounts of iron transfused. We studied 76 survivors of allogeneic and autologous BMT who were at least 1 year post-transplant and found that the majority (88%) had raised ferritins. Impaired liver function was common in these patients and in half was unexplained by viral hepatitis, veno-occlusive disease or graft-versus-host disease (GVHD), suggesting that iron overload may be an important contributing factor to liver disease in the stable post-transplant setting. This view is supported by the observation of improving liver function tests in 10 patients after a trial of venesection therapy.
