Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1]
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]
D. latum causes B12 deficiency in humans [10] leading to megaloblastic or pernicious anemia. [ 11 ] [ 12 ] The worm absorbs around 80% of dietary B12 and prolonged infection can also cause abdominal pain, mechanical obstruction, and symptoms of iron deficiency anemia. [ 13 ]
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.
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.
A long-term deficiency in vitamin B 12 can lead to megaloblastic anemia, characterized by large fragile red blood cells. Pernicious anaemia results from autoimmune destruction of gastric parietal cells, precluding the synthesis of intrinsic factor and, by extension, absorption of vitamin B 12. Pernicious anemia also leads to megaloblastic anemia.
[1] [8] Endoscopy, a type of X-ray known as an upper gastrointestinal series, blood tests, and stool tests may help with diagnosis. [1] Other conditions with similar symptoms include inflammation of the pancreas, gallbladder problems, and peptic ulcer disease. [2] Prevention is by avoiding things that cause the disease.
Praziquantel has few side effects, many of which are similar to the symptoms of diphyllobothriasis. [6] Niclosamide. An alternative treatment is niclosamide, 2 g orally once for adults or 50 mg/kg (max 2 g) for children. [16] [17] [18] Niclosamide is not available for human or even animal use in the United States.
