Changes in hemoglobin (Hb) levels prior to and following the switch from epoetin-β to epoetin-κ in patients injected with 750 units once or twice a week. The examination was conducted by dividing the patients into three groups. Group N-N, patients with Hb levels ranging between 10 and 12 g/dl prior to and subsequent to the change to epoetin-κ; Group L, patients with Hb levels that decreased to <10 g/dl at least once prior to the change to epoetin-κ; Group H, patients with Hb levels that increased to >12 g/dl at least once prior to switching over to epoetin-κ. Month 0: switch from epoetin-β to epoetin-κ.
