Megaloblastic anemia is a type of macrocytic anemia. An anemia is a red blood cell defect that can lead to an undersupply of oxygen. [1] Megaloblastic anemia results from inhibition of DNA synthesis during red blood cell production. [2] When DNA synthesis is impaired, the cell cycle cannot progress from the G2 growth stage to the mitosis (M ...
Anemia is defined as a condition in which there are not enough red blood cells, as the tissues and organs of the body do not get enough oxygen. Megaloblastic anemia caused by vitamin B 12 deficiency is characterized by red blood cells that are larger than normal and are unable to deliver oxygen to the body's organs.
Neutrophil hypersegmentation is one of the earliest, most sensitive and specific signs of megaloblastic anemia (mainly caused by hypovitaminosis of vitamin B12 & folic acid). Nuclear hypersegmentation of DNA in neutrophils strongly suggests megaloblastosis when associated with macro-ovalocytosis.
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]
Defined as those seen in any macrocytic, megaloblastic anemia: [1] Anemia: causing fatigue, conjuctival pallor, pale complexion, and in some cases, a mild icterus (yellowing of the eye). Glossitis ("shiny tongue"): shiny, glossy tongue. Cheilosis (stomatitis): Inflammation of the edges of the lips and the oral mucosa.
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
Symptoms of insufficient vitamin B12 can include fatigue, palpitations, pale skin, numbness, weight loss, infertility, dementia and megaloblastic anemia (when the body produces large, abnormal red ...
The main type of vitamin B12 deficiency anemia is pernicious anemia, [30] characterized by a triad of symptoms: Anemia with bone marrow promegaloblastosis ( megaloblastic anemia ). This is due to the inhibition of DNA synthesis (specifically purines and thymidine ).
