[Successful treatment with deferoxamine in a case of refractory anemia].
A 60-year-old female was admitted to our hospital because of macrocytic anemia with anisopoikilocytosis and thrombocytopenia. A bone marrow aspiration revealed hypolasia with nuclear deformity of neutrophils and decrease of megakaryocytic numbers. Karyotype analysis showed 47, XX, +8. A diagnosis of refractory anemia was made. The patient was treated with metenolone acetate without clinical response. Deferoxamine (2g/day) was given intravenously by continuous infusion. Ten days after deferoxamine treatment, the levels of RBC and platelet increased and the effect lasted 100 days after discontinuance of deferoxamine. Bone marrow aspiration showed normoplasia with normal megakaryocytes numbers. However, anisopoikilocytosis, abnormality of MCH and MCHC, and karyotype abnormality similar to the first medical examination remained. These data might suggest that deferoxamine induced differentiation of abnormal hemopoietic cells in refractory anemia. Retrobulbar neuritis which developed 30 days after initiation of treatment disappeared after halting deferoxamine treatment.
