Erythropoietin (/ ɪ ˌ r ɪ θ r oʊ ˈ p ɔɪ. ɪ t ɪ n,-r ə-,-p ɔɪ ˈ ɛ t ɪ n,-ˈ iː t ɪ n /; [1] [2] [3] EPO), also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted mainly by the kidneys in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow.
In addition, erythropoietin is bound by circulating red blood cells; low circulating numbers lead to a relatively high level of unbound erythropoietin, which stimulates production in the bone marrow. Recent studies have also shown that the peptide hormone hepcidin may play a role in the regulation of hemoglobin production, and thus affect ...
Latent iron deficiency (LID), also called iron-deficient erythropoiesis, [1] is a medical condition in which there is evidence of iron deficiency without anemia (normal hemoglobin level). [2]
The 2020 Cochrane Anaesthesia Review Group review of erythropoietin (EPO) plus iron versus control treatment including placebo or iron for preoperative anaemic adults undergoing non‐cardiac surgery [11] demonstrated that patients were much less likely to require red cell transfusion and in those transfused, the volumes were unchanged (mean ...
Marrow defects include nutritional deficiencies (i.e. iron, folate, or B 12) or insufficient erythropoietin, the stimulus for red blood cell production. Reticulocytopenia , or "aplastic crisis", is the medical term for an abnormal decrease of reticulocytes in the body The reticulocyte production index may find new use as a more reliable ...
Preterm infants are often anemic and typically experience heavy blood losses from frequent laboratory testing in the first few weeks of life. [4] Although their anemia is multifactorial, repeated blood sampling and reduced erythropoiesis with extremely low serum levels of erythropoietin (EPO) are major causative factors.
Erythropoietin is a sialoglycoprotein hormone produced by peritubular cells of kidney. Granulocyte -macrophage colony-stimulating factor and granulocyte CSF are given to stimulate white blood cell formation in cancer patients who are receiving chemotherapy , which tends to kill their red bone marrow cells as well as the cancer cells.
Erythropoietin (EPO) is a hormone that stimulates erythropoiesis, which can also be given as a medicine to increase the hemoglobin content of the blood, but EPO is not classified as a hematinic as it is not considered a nutrient, but a hormone.
