Erythropoiesis-stimulating agent, commonly abbreviated ESA, an agent similar to the cytokine (erythropoietin) that stimulates red blood cell production (erythropoeisis). ESAs, structurally and biologically, are similar to naturally occurring protein erythropoietin.
- Erythropoietin (Epo)
- Epoetin alfa (Procrit/Epogen)
- Epoetin beta (NeoRecormon)
- Darbepoetin alfa (Aranesp)
- Methoxy polyethylene glycol-epoetin beta (Mircera)
ESAs are used to maintain hemoglobin at the lowest level that both minimizes transfusions and best meets a person's needs. Medical speciality professional organizations do not recommend the use of ESAs in people with chronic kidney disease (CKD) who have hemoglobin levels greater than 10 g/dL and do not have anemia symptoms.
There is no evidence that one agent is better than another in the setting of CKD.
Causes of ineffectiveness
- Iron status
- Occult blood loss
- Vitamin B12 or folate deficiency
- Infection and inflammation
- Inadequate dialysis
- Aluminum toxicity
- Patient adherence
- Primary disease activity
- Transplant rejection
- Pure red cell aplasia
