The use of recombinant human erythropoietin (rHuEPO) is a major advance in the treatment of patients with anemia caused by chronic renal failure (CRF). The development of antierythropoietin (anti-EPO) antibodies following treatment with rHuEPO has been observed in an increasing number of patients. This causes pure red cell aplasia (PRCA) and requires the definitive withdrawal of rHuEPO. Many patients require immunosuppressive therapy before anti-EPO antibodies disappear completely. We report a case of PRCA owing to anti-EPO in a 20-year-old hemodialyzed man who was receiving immunosuppressive therapy for a liver transplantation carried out in childhood. He required repeated red cell transfusions until a kidney transplantation was performed. He received an induction therapy with antithymocyte globulins and a maintenance regimen consisting of steroids, tacrolimus and mycophenolate mofetil. This new immunosuppressive treatment led to the complete disappearance of anti-EPO antibodies within a few weeks after the kidney transplantation. Erythropoiesis and endogenous erythropoietin synthesis were restored following transplantation, without leading to an increase in the titer of anti-EPO antibodies.
