Brief summary
The purpose of this study is to ask whether treating non-diabetic chronic kidney disease (CKD) patients with GFR 8-20mL/min/1.73m2 by darbepoetin Alfa targeting Hb between 11.0 and 13.0g/dL preserves renal function better than targeting Hb between 9.0 and11.0g/dL. The investigators also ask whether the higher Hb targeting 11 to 13g/dL will not cause higher adverse events regarding cardiovascular diseases compared with lower Hb targeting 9 to 11g/dL.
Detailed description
Anemia is common among patients with chronic kidney disease (CKD) and is associated with an increased risk of cardiovascular and renal events. Although erythropoiesis stimulating agent (ESA) has been used to correct anemia, use of ESA (hemoglobin level at approximately 13 g/dL) did not reduce cardiovascular or renal events in diabetic CKD patients. Subgroup analysis of a recent randomized study suggested that use of darbepoetin alfa targeting Hb between 11 and 13 g/dL may preserve renal function better than targeting Hb between 9 and 11g/dL in non-diabetic CKD patients.
Interventions
Darbepoetin alfa is used for targeting Hb level of 11-13g/dL in high Hb group, and 9-11g/dL in low Hb group.
