WebDec 6, 2024 · Lastly, because iron functions in concert with erythropoietin to promote erythroid precursor survival, proliferation, and differentiation, iron deficiency anemia is a consequence not only of decreased hemoglobin synthesis in each cell but also, a decrease in erythropoietin responsiveness in the bone marrow. WebIron is an essential component in hematopoiesis and, as such, should supplement ESA treatment. In 1989, the introduction of ESAs led to a renewed interest in parenteral iron therapy. After initiation of ESA therapy, functional iron deficiency occurred in almost every patient as the result of the non-physiologic administration of ESA. 1
