This retrospective review assesses the efficacy of darbepoetin alfa for treating anemia after renal transplantation. Patients were evaluated over a 12-week period, and efficacy was based on achieving hemoglobin >12 g/dL. Thirty-six patients were analyzed (53% male, 53% cadaveric allografts, median age 42.5 years). Baseline creatinine clearance ranged from approximately 15 to >100 mL/min. Most patients initiated darbepoetin alfa <3 months (50%) or >12 months (44%) after transplantation, 19% were previously receiving recombinant human erythropoietin (rHuEPO), and 47% were on concomitant ACE inhibitors. The majority of patients received either tacrolimus- (53%) or cyclosporine- (44%) based immunosuppression. Overall, 29 (81%) patients achieved the hemoglobin target with a mean time to response of 4.4 weeks. Neither the time to anemia onset, previous rHuEPO therapy, concomitant ACE inhibitor, allograft source, immunosuppressive regimen, nor degree of renal function affected the proportion of patients achieving the hemoglobin target, time to response or darbepoetin alfa dose requirement. Patients with anemia >12 months post-transplantation or on concomitant ACE inhibitors required a significantly longer duration of therapy. No adverse events associated with darbepoetin alfa therapy were detected. These results demonstrate that darbepoetin alfa is a safe and effective treatment for anemia in renal transplant recipients.
