  Purpose

Recombinant human erythropoietin (r-HuEpo) has been used to treat renal anemia and improve morbidity and mortality in chronic kidney disease. Subcutaneous use of r-HuEpo causes immunogenicity and develops anti-r-HuEpo associated pure red cell aplasia (PRCA). The treatment of anti-r-HuEpo associated pure red cell aplasia is controversial. The investigators aim to evaluate the treatment for anti-r-HuEpo associated pure red cell aplasia in this study.

Primary Outcome Measures:
  • anti-r-HuEpo antibody [ Time Frame: Day 0 and month 6 ] [ Designated as safety issue: No ]
    The anti-r-HuEpo antibody titer at day 0 (before treatment) and month 6 (6th month after treatment) of each arm will be compared


Secondary Outcome Measures:
  • Absolute reticulocyte count [ Time Frame: Day 0 and month 6 ] [ Designated as safety issue: No ]
    The Absolute reticulocyte count at day 0 (before treatment) and month 6 (6th month after treatment) of each arm will be compared

Detailed Description:

Recombinant human erythropoietin was the first biotherapeutic medicinal product derived from recombinant DNA technology for the treatment of anemia in patients with chronic kidney disease (CKD). Although r-HuEpo raises hemoglobin levels in CKD and improves morbidity associated with anemia in CKD patients, the adverse immunological effect of r-HuEpo administered subcutaneously can result in anti-r-HuEpo associated PRCA. We aim to evaluate the effectiveness of two treatment protocol, cyclosporine combined with mycophenolate mofetil and cyclophosphamide combined with prednisolone for treatment of anti-r-HuEpo associated PRCA.
