Intravenous iron treatment in hemodialysis patients improves response to recombinant human erythropoietin and facilitates achievement of targets for hemoglobin and hematocrit. Excessive treatment, however, could expose patients to risks related to iron overload and oxidative stress. Therefore, international treatment guidelines generally recommend that intravenous (i.v.) iron be discontinued when serum ...

Darbepoetin alfa (KRN321) is a novel molecule that stimulates erythropoiesis by the same mechanism as endogenous erythropoietin. Due to its longer half-life and greater biological activity than recombinant human erythropoietin (rHuEPO), KRN321 maintains an effective hemoglobin (Hb) level at extended dose intervals compared with rHuEPO. This multicenter, open-label, single-arm study ...
