Erythropoietin 항체에 의해 유발된 진성 적혈구 무형성증 (Pure Red-cell Aplasia) 1예

Abstract

Recombinant human erythropoietin (rHuEPO) is extensively used in anemic patients on dialysis. We experienced a case of pure red-cell aplasia (PRCA) caused by anti-rHuEPO Antibody. A 48-year-old male with CRF was placed on chronic hemodialysis. He developed severe anemia (Hb 6.6 g/dL) without any apparent blood loss. A transfusion was given and the rHuEPO dose was increased to 12, 000 U/week SC. A bone marrow study was carried out. Anti-rHuEPO antibodies were positive. rHuEPO therapy was stopped. No improvement in the anemia was apparent. Although very rare, anti-rHuEPO antibodies should be evaluated in patients with severe anemia without obvious etiology.
