Abstract
Background: The kidney plays a fundamental role in erythropoiesis, through the endogenous production of erythropoietin, in response to hypoxia. Exogenous erythropoietin supplementation, through the use of erythropoiesis-stimulating agents, together with correction of iron deficiency, has been the standard treatment for the treatment of anemia associated with kidney disease.
Contents: The need for high doses of erythropoiesis-stimulating agents to achieve a target hemoglobin level has been related to resistance to erythropoietin, a greater number of adverse effects, and higher mortality. This review analyzes the role of new molecules in the treatment of renal anemia, focusing on the benefit that their use can have in cases of resistance to erythropoietin.
Conclusions: The development of new molecules to treat renal anemia, such as stabilizers of hypoxia-inducible factor, allow endogenous stimulation of erythropoietin and improve the bioavailability of iron, in patients with resistance to erythropoietin where they could play a prominent role with close supervision.
