Signs of folate deficiency anemia most of the time are subtle. [4] Anemia (macrocytic, megaloblastic anemia) can be a sign of advanced folate deficiency in adults. [1] Folate deficiency anemia may result in feeling tired, weakness, changes to the color of the skin or hair, open sores on the mouth, shortness of breath, palpitations, lightheadedness, cold hands and feet, headaches, easy bleeding ...
In absence of vitamin B 12, levels of methylmalonyl CoA increase, and this is in fact a great way to distinguish folate deficiency macrocytic anemia, from vitamin B 12 deficiency anemia. The following is the reaction in which Ado B 12, plays a pivotal role: Propionyl CoA → Methylmalonyl CoA → Succinyl CoA [5]
Serum levels above 50 μg/L are associated with side effects. In rare cases, sulfasalazine can cause severe depression in young males. It can also cause oligospermia and temporary infertility. Immune thrombocytopenia has been reported. [12] Sulfasalazine inhibits dihydropteroate synthase, and can cause folate deficiency and megaloblastic anemia.
Pernicious anemia is the most common cause of vitamin B 12 deficiency anemia in adults, which results from malabsorption of vitamin B 12 due to a lack or loss of intrinsic factor. [ 2 ] [ 8 ] There are relatively few studies which have assessed the impact of haematological measures in response to B 12 supplementation.
Folate-deficiency anemia: D52 E53.8: 4894: 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 ...
Folate in the form of folic acid is used to treat anemia caused by folate deficiency. [3] Folic acid is also used as a supplement by women during pregnancy to reduce the risk of neural tube defects (NTDs) in the baby. [3] [10] NTDs include anencephaly and spina bifida, among other defects.
Vitamin B 12 deficiency prevents the 5-methyltetrahydrofolate (5-MTHF) form of folate from being converted into THF due to the "methyl trap". [18] This disrupts the folate pathway and leads to an increase in homocysteine which damages cells (for example, damage to endothelial cells can result in increased risk of thrombosis). [citation needed]
Macrocytic anemias have several causes but with the implementation of folic acid fortification in North America, folate deficiency has become a rare cause of megaloblastic macrocytic anemia in that part of the world. [1] In this region, Vitamin B 12 deficiency is a far more common cause of megaloblastic macrocytic anemia. [1]
