Which statement correctly identifies an indication for erythropoiesis-stimulating agents (ESAs)?

• A. Indicated for iron overload
• B. Indicated for active infection
• C. Indicated for CKD-related anemia or chemo-induced anemia
• D. Indicated for anemia due to B12 deficiency

Answer: (C)

Erythropoiesis-stimulating agents are used to treat anemia that results from insufficient erythropoietin activity or bone marrow suppression, such as in chronic kidney disease or during chemotherapy. They stimulate the bone marrow to produce more red blood cells, which helps raise hemoglobin and reduce the need for transfusions in these specific scenarios. This is why the statement indicating CKD-related anemia or chemo-induced anemia is the correct indication. They are not used for iron overload—giving an ESA won’t remove excess iron and can’t address the underlying problem. They’re also not given during active infection, since treating the infection takes precedence and ESA use isn’t indicated in that context. Anemia caused by vitamin B12 deficiency isn’t treated with ESAs either; the deficiency must be corrected with B12, after which normal RBC production can resume.
