Recovery of pure red-cell aplasia secondary to antierythropoietin antibodies after cessation of recombinant human erythropoietin.

摘要

Abstract We describe a patient with end-stage renal failure (ESRF) who developed anti-erythropoietin (anti-EPO) antibodies and pure red-cell aplasia (PRCA) after using Eprex (Janssen-Cilag, Sydney). Anti-EPO antibodies were detected with an immunoprecipitation technique and were shown to inhibit erythropoiesis in vitro. Antibody levels waned upon ceasing Eprex. The patient required transfusions for 21 months then recovered after immunosuppression. (Intern Med J 2003; 33: 468-471)
