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]
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.
Nutritional anemia can be caused by a lack of iron, protein, vitamin B12, and other vitamins and minerals that are needed for the formation of hemoglobin. However, Iron deficiency anemia is the most common nutritional disorder. [7] Signs of anemia include cyanosis, jaundice, and easy bruising. [7]
The types of anemia treated with drugs are iron-deficiency anemia, thalassemia, aplastic anemia, hemolytic anemia, sickle cell anemia, and pernicious anemia, the most important of them being deficiency and sickle cell anemia with together 60% of market share because of highest prevalence as well as higher treatment costs compared with other ...
Anemia is prevalent in these nations, with unacceptable rates of iron deficient anemia. [2] The nutritional status of children is further indicated by its high (10%) rate of child wasting. [ 2 ] Wasting is a significant problem in Sahelian countries – Burkina Faso , Chad , Mali , Mauritania and Niger – where rates fall between 11% and 19% ...
It is mainly used to differentiate an anemia of mixed causes from an anemia of a single cause. Deficiencies of Vitamin B 12 or folate produce a macrocytic anemia (large cell anemia) in which the RDW is elevated in roughly two-thirds of all cases. However, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and ...
Symptoms of AIHA may be due to the underlying anemia; including shortness of breath or dyspnea, fatigue, headache, muscle weakness and pallor. [10] In cold agglutinin disease (cold antibody type), agglutination and impaired passage of red blood cells through capillaries in the extremities causes acrocyanosis and Raynaud phenomenon with a rare complication of gangrene [4]
William Parry Murphy Sr. (February 6, 1892 – October 9, 1987) was an American physician who shared the Nobel Prize in Physiology or Medicine in 1934 with George Richards Minot and George Hoyt Whipple for their combined work in devising and treating macrocytic anemia (specifically, pernicious anemia).
