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


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… (More)
