Recovery of erythropoiesis following allogeneic bone marrow transplantation for chronic lymphocytic leukaemia-associated pure red cell aplasia

Pure red cell aplasia is a rare condition, that can be either idiopathic or associated with a lymphoproliferative disorder. The latter is considered to result from T cell-mediated suppression of haematopoiesis, and usually responds well to treatment with immunosuppressive medication. We describe a patient with B-CLL-associated pure red cell aplasia who did not respond to several courses of immunosuppressive treatment. Erythropoiesis was finally restored after allogeneic bone marrow transplantation.
