title: [Treatment with bolus methylprednisolone for pure red cell aplasia after ABO incompatible bone marrow transplantation in a patient with chronic myelocytic leukemia].
abstract: Pure red cell aplasia (PRCA) was found in a male patient with chronic myelocytic leukemia after major ABO incompatible bone marrow transplantation (BMT). He had blood group O, and received BMT from an HLA identical sibling (blood group A). Erythrocyte-depleted marrow was transplanted. Methotrexate for short time and cyclosporine (CyA) were used for graft versus host disease (GVHD) prophylaxis. Engraftment of neutrophils and platelets were observed on day 14 and 22, respectively. The Ph1 chromosome disappeared on day 133. However engraftment of erythrocytes was not observed on day + 280. Bone marrow puncture revealed depletion of erythrocyte precursors. Anti-A isoagglutinin was persisted. There was no evidence of acute or chronic GVHD. Administration of prednisolone, discontinuance of CyA and subcutaneous infusion of recombinant human erythropoietin failed to improve PRCA. Bolus methylprednisolone (m-PSL) therapy started on day 284 resulted in rapid increase in reticulocyte counts within 6 days, which was followed by normal hemoglobin concentrations. We conclude that bolus m-PSL may be one treatment for PRCA after BMT.
