Pernicious anemia is the most common cause of clinically evident vitamin B 12 deficiency worldwide. [14] Pernicious anemia due to autoimmune problems occurs in about one per 1000 people in the US. Among those over the age of 60, about 2% have the condition. [8] It more commonly affects people of northern European descent. [2]

Autoimmune hemolytic anemia: Anti-red blood cell antibodies Confirmed 1-3 per 100,000 [89] Immune thrombocytopenia: Anti-platelet antibodies Confirmed 3.3 per 100,000 (adults), 50 per 100,000 (children) [90] Thrombotic thrombocytopenic purpura: ADAMTS13 autoantibodies Confirmed 1-2 per million [91] Antiphospholipid ...
Higher red blood cell diameter and wider variation in size are often seen in pernicious anaemia. [3] Lower diameter with normal variation in size are often seen after haemorrhage . [ 3 ] A higher variation in size is known as anisocytosis .
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.

Pernicious anemia: D51.0: 9870: Pernicious anemia (also known as macrocytic achylic anemia, congenital pernicious anemia, juvenile pernicious anemia, and Vitamin B12 deficiency) is one of many types of the larger family of megaloblastic anemias. It is caused by loss of gastric parietal cells, and subsequent inability to absorb vitamin B 12.
Anemia of kidney failure [35] due to insufficient production of the hormone erythropoietin; Anemia of endocrine disease [36] Disturbance of proliferation and maturation of erythroblasts. Pernicious anemia [35] is a form of megaloblastic anemia due to vitamin B 12 deficiency dependent on impaired absorption of vitamin B 12.
During the 1920s, George Whipple discovered that ingesting large amounts of raw liver seemed to most rapidly cure the anemia of blood loss in dogs, and hypothesized that eating liver might treat pernicious anemia. [145] Edwin Cohn prepared a liver extract that was 50 to 100 times more potent in treating pernicious anemia than the natural liver ...
