Due to a higher risk of stomach cancer, those with pernicious anemia should be checked regularly for this. [13] The first clear description was by Thomas Addison in 1849. [ 16 ] [ 17 ] The term "pernicious" means "deadly", and this term came into use because, before the availability of treatment, the disease was often fatal.
Animals, including humans, can convert cyanocobalamin to any one of the active vitamin B 12 compounds. [21] Cyanocobalamin is one of the most widely manufactured vitamers in the vitamin B 12 family (the family of chemicals that function as B 12 when put into the body), because cyanocobalamin is the most air-stable of the B 12 forms. [22]
[2] [4] Plants do not need cobalamin and carry out the reactions with enzymes that are not dependent on it. [5] Vitamin B 12 is the most chemically complex of all vitamins, [6] and for humans the only vitamin that must be sourced from animal-derived foods or supplements. [2] [7] Only some archaea and bacteria can synthesize vitamin B 12. [8]
Hydroxocobalamin, also known as vitamin B 12a and hydroxycobalamin, is a vitamin found in food and used as a dietary supplement. [1] As a supplement it is used to treat vitamin B12 deficiency including pernicious anemia. [1] [2] Other uses include treatment for cyanide poisoning, Leber's optic atrophy, and toxic amblyopia.
Sideroblastic anemias are often described as responsive or non-responsive in terms of increased hemoglobin levels to pharmacological doses of vitamin B 6. [citation needed] 1- Congenital: 80% are responsive, though the anemia does not completely resolve. 2- Acquired clonal: 40% are responsive, but the response may be minimal.
Also known as cobalamin, think of vitamin B12 as fuel for your engine—it plays essential roles in energy production within your body, says Stephanie Gray, D.N.P., M.S.,
Folate-deficiency anemia (also known as dietary folate-deficiency anemia) is a condition that develops when the body does not have the adequate supply of folic acid available that is needed for the production of new healthy blood cells. [13] Nutritional megaloblastic anemia: D51.1, D52.0, D53.1: 29507: D000749
This leads to continuing cell growth without division, which presents as macrocytosis. Megaloblastic anemia has a rather slow onset, especially when compared to that of other anemias. The defect in red cell DNA synthesis is most often due to hypovitaminosis, specifically vitamin B12 deficiency or folate deficiency. Loss of micronutrients may ...
