title: [Recombinant human erythropoietin (KRN5702) therapy for autologous blood transfusion in patients with rheumatoid arthritis undergoing joint replacement surgery--a multicenter phase II clinical trial].
abstract: In order to evaluate the effect of recombinant human erythropoietin (rHuEPO) on autologous blood transfusion in patients with rheumatoid arthritis (RA), we performed a phase II clinical trial in 65 RA patients undergoing elective surgery. rHuEPO was administered subcutaneously once a week and after observing erythropoiesis, autologous blood was collected. Fifty-seven of the 58 patients who completed treatment responded to rHuEPO and could donate more than 400 ml of autologous blood. Among them, 23 out of 28 patients undergoing total hip arthroplasty, 27 out of 28 undergoing total knee arthroplasty and 1 out of 1 undergoing spinal surgery did not need homologous blood transfusion perioperatively. During rHuEPO treatment, no significant changes of clinical parameters of RA activity were observed. Two patients discontinued the treatment because of mild and transient side effects. These results indicate that subcutaneous rHuEPO is safe and effective in eliminate the need for homologous blood transfusion, even in anemic RA patients undergoing elective orthopedic surgery.
