Erythropoietin responsible for the hormonal regulation of red blood cell production. Its formation is largely controlled by the kidneys. A number of assay methods for erythropoietin are available. Asymptomatic patients with sickle cell disease have elevated erythropoietin levels, as expected with chronic hemolysis. When complicated by chronic renal failure, erythropoietin levels do not rise appropriately. Chronic infection has not been studied, but the erythropoietin response in acute infection does not seem to conform to a pattern. Aplastic crises are characterized by very high levels of erythropoietin, suggesting bone marrow suppression, but events that trigger the crises remain obscure. In vaso-occlusive crises, there is also some suggestion of mild and transient lack of bone marrow response. Patients with sickle cell disease, with their chronic high erythropoietin anemia and susceptibility to altered states, are uniquely suited for investigating the physiology of erythropoietin, especially under the constraints of present assay methods.
