✦ Synopsis

Pure red cell aplasia (PRCA) is an unusual complication of chronic lymphoproliferative disorders. A patient with T-cell chronic lymphocytic leukemia (T-CLL) had severe anemia and neutropenia. Initial in vitro studies demonstrated no evidence of T-cell suppression of erythropoiesis. Sequential bone marrow examinations demonstrated progressive red cell aplasia. In vitro studies showed that the T-cells from the patient suppressed allogeneic but not autologous BFU-E. Treatment with antithymocyte globulin (ATG) reduced circulating leukemic cells and produced a definite but transient improvement in erythropoiesis.

## BACKGROUND. T-cell lymphoid blastic phase (BP) transformation is rare in chronic myelogenous leukemia (CML). 2-amino-9-␤-D-arabinosyl-6-methoxy-9H-guanine (GW506U78), a prodrug of arabinosylguanine (ara-G), is effective in T-cell leukemias. ## METHODS. The authors present a case of a 48-year
