Clinical trials conducted in various countries indicate that the use of epoetin alfa in patients with nephrogenic anemia in chronic kidney disease can increase the effectiveness of treatment, reduce the incidence of cardiovascular and infectious complications, and reduce mortality in patients with chronic kidney disease.The aim of the article was to conduct a comparative clinical and economic assessment of the treatment costs of nephrogenic anemia in adult dialysis patients with recombinant human erythropoietins: epoetin alfa, darbepoetin and long-acting methoxy polyethylene glycol – epoetin beta.Materials and methods. The study took into account direct medical costs of nephrogenic anemia pharmacotherapy on the basis of 1 year maintenance therapy according to the following scheme: epoetin alfa – 3 times per week, darbepoetin alfa – once per week, methoxy polyethylene glycol – epoetin beta – once per 2 or 4 weeks. A “costs minimization” analysis was performed for equivalent maintenance epoetins doses for intravenous and subcutaneous administrations. Epoetin alpha equivalents were calculated for an average patient weighing 75 kg by converting a weekly dose of short-acting epoetin (7500 IU) into equivalent doses using dose conversion factors.Results. In the hypothetical cohort of patients under study, epoetin alfa, darbepoetin alfa, and methoxy polyethylene glycol – epoetin beta not differ in effectiveness in achieving target Hb values and in safety. With the equal effectiveness of the investigated drugs, in the studied patients, intravenous epoetin alfa can be less expensive drug therapy relative to the equivalent doses obtained by the calculation: darbepoetin by 14–24% and methoxy polyethylene glycol – epoetin beta by 4–30%. The change-over of patients to the subcutaneous administration makes it possible to decline a weekly dose of epoetin alfa by 20–30% by reducing the frequency of taking the drug to twice a week, and to reduce the cost of drug therapy by a third.Conclusion. Intravenous and subcutaneous administrations of epoetin alfa 2500 IU may be a more economical drug therapy in comparison with the equivalent doses of darbepoetin and methoxy polyethylene glycol – epoetin beta.
