Abstract

This Spanish single-arm, multicenter, prospective clinical trial assessed the maintenance of hemoglobin concentrations (Hb) between 10-13 g/dL with unit doses of darbepoetin alfa and the safety of the treatment in dialysis patients. Eight-hundred twenty-six patients with chronic renal failure (CRF) (94% receiving haemodialysis and 6% receiving peritoneal dialysis) previously maintained on stable recombinant human erythropoietin (r-HuEPO) therapy with stable hemoglobin (Hb) concentrations (mean Hb concentration = 11.7 g/dL) were switched to darbepoetin alfa at a reduced dosing frequency for 24 weeks (a 20-week titration phase plus a 4-week treatment evaluation phase). Subjects receiving r-HuEPO two or three times weekly were switched to darbepoetin alfa once weekly, and those. who were receiving r-HuEPO once weekly were switched to darbepoetin alfa once every two weeks. The initial dose of darbepoetin alfa was determined from the r-HuEPO dose at inclusion into the study using a formula equating the peptide mass of the two molecules and rounding to the nearest available prefilled syringe dose. Overall, 86.8% of patients completed the 24-weeks of study. Changing the treatment from r-HuEPO to darbepoetin alfa and increasing the dos...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
