Because pernicious anemia is due to a lack of intrinsic factor, it is not preventable. [11] Pernicious anemia can be treated with injections of vitamin B 12. [7] If the symptoms are serious, frequent injections are typically recommended initially. [7] There are not enough studies that pills are effective in improving or eliminating symptoms. [12]
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.
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.
Eponymous medical signs are those that are named after a person or persons, usually the physicians who first described them, but occasionally named after a famous patient. This list includes other eponymous entities of diagnostic significance; i.e. tests, reflexes, etc.
The most common are pernicious anemia possibly leading to vitamin B 12 deficiency; and malabsorption of iron, leading to iron deficiency anaemia. [2] It can be caused by persistent infection with Helicobacter pylori , or can be autoimmune in origin.
Pure red cell aplasia (PRCA) or erythroblastopenia refers to a type of aplastic anemia affecting the precursors to red blood cells but usually not to white blood cells. In PRCA, the bone marrow ceases to produce red blood cells. There are multiple etiologies that can cause PRCA. The condition has been first described by Paul Kaznelson in 1922. [1]
Pyruvate kinase deficiency is an inherited metabolic disorder of the enzyme pyruvate kinase which affects the survival of red blood cells. [4] [5] Both autosomal dominant and recessive inheritance have been observed with the disorder; classically, and more commonly, the inheritance is autosomal recessive.
A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia. [1] Exposure to cobalt metal dust is most common in the fabrication of tungsten carbide. [2] Another source is from wear and tear of certain metal-on-metal hip prostheses. [3]
