Recker RR. 18. Vitamin B12 deficiency. This global disease is most common in areas of the world that have extreme poverty or are over-crowded. When a bacterial infection is the cause of atrophic gastritis, a person may notice symptoms that include: When autoimmune atrophic gastritis is the cause, a person may notice symptoms of a vitamin B-12 deficiency and pernicious anemia. Atrophic gastritis is a histopathologic entity characterized by chronic inflammation of the gastric mucosa with loss of the gastric glandular cells and replacement by intestinal-type epithelium, pyloric-type glands, and fibrous tissue. 2012;57(10):2504–2515. v FIG. Roles of vitamins B5, B8, B9, B12 and molybdenum cofactor at cellular and organismal levels. 35, NO. Freedberg DE, Kim LS, Yang YX. It should be noted there may be endoscopic findings other than gastric body mucosal atrophy such as gastric polyps or Type I gastric neuroendocrine tumors (Image 1).

Gastritis is an often painful condition characterized by inflammation of the lining of the stomach. Determinants of diagnostic delay in autoimmune atrophic gastritis. Lenti MV, Miceli E, Cococcia S, et al. Younger patients are more likely to present with features of IDA whereas those over the age of 60, tend to have megaloblastic vitamin B12 deficiency. However, early detection and treatment can improve the overall outlook and reduce the risk of complications. Atrophic gastritis occurs when a person’s stomach lining is inflamed for an extended period, often for several years. Role of autoimmune gastritis, Helicobacter pylori and celiac disease in refractory or unexplained iron deficiency anemia. Autoimmune atrophic gastritis is much less common. To do a biopsy, a doctor will insert an endoscope, which is a long tube with a light on it, through the mouth and into the stomach. The updated Sydney system. vitamin B 12, iron, folate). Gastric acid plays an important role in calcium absorption as it increases the dissolution and ionization of poorly soluble calcium.22 Recker et al. In addition, other vitamin and micronutrient deficiencies (including vitamin D, calcium and vitamin C) have been known to occur in patients with CAG, although their frequency and likely mechanism of onset is less well understood. A recent study from Italy that looked at 291 patients with CAG found that the median overall diagnostic delay was 14 months (interquartile range [IQR] 4-41), particularly amongst gastroenterologists.10 Clearly there is a need for increased education and awareness of this condition, and treating physicians need to maintain a high index of suspicion. Risk of gastric adenocarcinoma increases 3-fold. Aditi A, Graham DY. Nat Prod Rep 2007;24: 949-962. A role of CAAG in the pathogenesis of nutritional deficiencies has been reported, therefore we hypothesized a possible association between CAAG and 25-OH-Vitamin D [25(OH)D] deficiency. Symptoms include: pain in the chest Here, the immune system attacks the healthy cells in the stomach lining. A recent study from Italy evaluated the prevalence of 25-OH-vitamin D (25(OH) D) deficiency in a cohort of 87 patients with CAG. 15. 8. Stomach acid is vital to the absorption process of the vitamins and minerals found in our food. They found in the CAG group, the mean 25(OH) D levels were significantly lower than in the control group (18.8 vs. 27.0 ng/ ml, p < 0.0001). A person is most at risk of atrophic gastritis if they come into contact with H. pylori. There are many ways a person can come into contact with the H. pylori bacterium. Also, treatment for autoimmune atrophic gastritis will likely focus on ensuring a person is not iron deficient. Elevated plasma homocysteine is now recognized as an independent risk factor for cardiovascular disease and seems to play an important role in the development of dementia, diabetes mellitus and renal disease.9 Homocysteine is also elevated in folate deficiency. Helicobacter. A patient with an unexplained iron deficiency anemia should have atrophic gastritis (and concomitant H. pylori) excluded. Oral vitamin B12 versus intramuscular vitamin B12 for vitamin B12 deficiency. Clin J Gastroenterol (2014) 7:381386. 29. Older studies proposed a deficiency of vitamin C due to malabsorption, insufficient intake, increased metabolic requirement and rapid destruction in the GI tract.27 Elevated pH (from achlorhydria) and bacterial overgrowth may also be a factor.28 Alt et al. University of Michigan Medical Center Division of Geriatric Medicine Ann Arbor, … A deficiency of vitamin B12 is well described, but often diagnosed late. This live article contains regularly updated information on the experimental vaccines being developed for COVID-19. Studies on ascorbic acid deficiency in gastric diseases: Incidence, diagnosis, and treatment. Eastell R, Vieira NE,Yergey AL, et al. A lack of intrinsic factor can cause an illness called pernicious anemia. Stabler SP. 5 To the Editor-The recent paper by Krasinski et al.' Gut. The classic neurological presentation of a patient with PA is proprioceptive sensory loss with ataxic gait abnormalities, demyelinating peripheral sensory-motor polyneuropathies and paresthesias. 22. British Society of Gastroenterology guidelines on the diagnosis and management of patients at risk of gastric adenocarcinoma. The prevalence of severe atrophic gastritis, but not mild-to-moderate atrophic gastritis, was higher in mildly cobalamin-deficient subjects (25%) than in non-cobalamin-deficient subjects (3.7%) (chi2 = 4.6, P = 0.032). 28. Massironi S, Zilli A, Elvevi A, et al. In cases of autoimmune atrophic gastritis, a doctor may prescribe B-12 injections. When a person has autoimmune atrophic gastritis, their body mistakenly attacks healthy stomach cells, including a substance called intrinsic factor. Aim of the Treatments differ, depending on the cause, but diet and lifestyle can improve the outlook in both cases. with atrophic gastritis and a study reported that H. pylori was found in 56% of people with vitamin B12 deficiency. A biopsy will help the doctor to diagnose the cause of a person’s symptoms and confirm whether or not they have atrophic gastritis. Pernicious anemia accounts for 15% to 25% of vitamin B12 deficiency in elderly people. Subjects with mild vitamin B12 deficiency (vitamin … A patient with iron deficiency anemia that is unknown may have atrophic gastritis The cause of atrophic gastritis (AG) is either (i) the immune-mediated destruction by antibodies (IF and/ or parietal cell) directed against the gastric mucosa (termed chronic atrophic autoimmune gastritis (CAAG)) or (ii) Helicobacter pylori (H. pylori) infection. Find out more about these and other ways of reducing cholesterol…. Atrophic gastritis results in a low acid-pepsin secretion by the gastric mucosa, which in turn results in a reduced release of free vitamin B 12 from food proteins. 6. These include: Very often, a person may not know they have atrophic gastritis, as they may not have any noticeable symptoms. 1938; 62:330–336. Intrinsic factor is a protein released by stomach cells that helps absorb vitamin B-12. Vitamin B12 deficient patients have less osteoblastic activity and bone formation24 and greater risk of bone fracture.25 Of note, both men and women with lower vitamin B12 levels had lower average bone mineral density than controls.26 More research into the relationship between vitamin B12, vitamin D and calcium deficiency, and their potential association with reduced bone mineral density and increased fracture risk in patients with CAG, is needed. Vitamin C, gastritis, and gastric disease: a historical review and update. For this reason, a diagnosis of the condition may never happen in a person who has had it for years. 10. >400 3nr 350-1 1^1 X 300 1" 250-m i i 200-IDoz oa<-O 150-O > 100-zO0 500 La PA.Range Pre-pernicdus Anoemiaj Normal 1 _3 _-5----I.II I 10 is 20 25 ij L 30 D-Boo% I! CAAG may occur as part of the polyglandular autoimmune syndrome and may be associated with other autoimmune diseases such as type I diabetes, vitiligo, and thyroid disease; therefore, these associated conditions should be considered during the evaluation of CAG. 13. In CAAG, the presence of autoantibodies directed against IF and/or parietal cells results in pernicious anemia (PA). Annibale B, Marignani M, Monarca B, et al. Chronic autoimmune atrophic gastritis (CAAG) is an autoimmune disease characterized by hypo/achlorhydria. 2019 Sep;68(9):1545-1575. A deficiency of folate can result in a similar clinical picture. A role of CAAG in the pathogenesis of nutritional deficiencies has been reported, therefore we hypothesized a possible association between CAAG and 25-OH-Vitamin D [25(OH)D] deficiency. Around half of people with H. pylori-related gastritis will develop atrophic gastritis. A bacterial infection usually causes atrophic gastritis, but it can also be an autoimmune condition. Light headedness, shortness of breath and lethargy due to iron deficiency anemia. The other conditions causing vitamin B12 deficient megaloblastic anemia (Table 1) need to be differentiated from CAAG which causes PA from IF deficiency. Doctors mostly find inflammation in the mucous membrane of a person’s stomach lining. Autoimmune metaplastic atrophic gastritis is an inherited autoimmune disease that attacks parietal cells, resulting in hypochlorhydria and decreased production of intrinsic factor. Both vitamin B12 and folate defi… A doctor will treat atrophic gastritis by focusing on the underlying cause. 19. Atrophic gastritis is a chronic form of gastritis. This leads to various digestive problems. This parietal cell loss leads to reduced gastric acid secretion and decreased IF production. Atrophic gastritis, regardless of its cause, leads to nutritional deficiencies through parietal cell atrophy and the resulting achlorhydria. A patient with an unexplained iron deficiency anemia should have atrophic gastritis (and concomitant H. pylori) excluded. This test involves swallowing a substance that contains particular carbon molecules and then breathing into a test tube. These cookies do not store any personal information.
