	eMedicine - Gastritis, Atrophic : Article by Antonia R Sepulveda, MD, PhD
		H pylori–associated atrophic gastritis usually is a multifocal process that involves both the antrum and oxyntic mucosa of the gastric corpus and fundus, while autoimmune gastritis essentially is restricted to the gastric corpus and fundus.
		Atrophic gastritis is detected late in life because it results from the effects of long-standing damage to the gastric mucosa.
		Autoimmune atrophic gastritis is a type of chronic atrophic gastritis limited to corpus-fundus mucosa and characterized by marked diffuse atrophy of parietal and chief cells.

	Autoimmune Gastritis
		The aim of this study was to investigate the prevalence and role of H. pylori in a prospectively investigated population of patients with corpus-predominant atrophic gastritis.
		The present controls differed from the atrophic gastritis series in that the topography of gastritis was different and in that the incidence of metaplasia, atypia, gastric antibodies and high serum gastrin levels was markedly lower.
		Morphology and pathogenesis of endocrine hyperplasias, precarcinoid lesions, and carcinoids arising in chronic atrophic gastritis.

	eMedicine - Gastritis, Chronic : Article by Antonia R Sepulveda, MD, PhD
		Multifocal atrophic gastritis is characterized by involvement of the corpus and gastric antrum with progressive development of gastric atrophy (loss of the gastric glands) and partial replacement of gastric glands by an intestinal-type epithelium (intestinal metaplasia).
		This is a type of chronic gastritis with dense infiltration of the surface and foveolar epithelium by T lymphocytes and associated chronic infiltrates in the lamina propria.
		Atrophic gastritis may be assessed by measuring serum levels of the pepsinogen I–to–pepsinogen II ratio.

	Chapter 28 (page 133)
		Strickland and Mackay (l973) reviewed the nature of chronic atrophic gastritis in relation to the structure and function of the pyloric antrum, where "antrum" was equated with the pyloric mucosal zone.
		Benign gastric ulceration of the corpus was found to be associated with Type B atrophic gastritis; the more proximally the ulcer was located in the stomach, the more extensive the gastritis and the more severe the impairment of acid secretion proved to be.
		In atrophic gastritis the essential feature was not the increase in inflammatory cells in the lamina propria, but the reduction or atrophy of the deep glands, accompanied by intestinal metaplasia in the "antrum".

		Gastritis may be caused by infections with bacteria, viruses, or fungi.
		Postgastrectomy gastritis is thought to result when surgery impairs blood flow to the stomach lining or exposes the stomach lining to an excessive amount of bile (the greenish yellow digestive fluid produced by the liver).
		Atrophic gastritis occurs when antibodies (see Biology of the Immune System: Antibodies) attack the stomach lining, causing it to become very thin and to lose many or all of the cells that produce acid and enzymes.

	Gastritis
		Gastritis isn't one disease but a group of conditions, all of which are characterized by inflammation of the lining of your stomach.
		Gastritis that occurs suddenly (acute gastritis) usually results in the classic combination of nausea and burning pain or discomfort in your upper abdomen, whereas chronic gastritis, which develops gradually, is more likely to cause a dull pain and a feeling of fullness or loss of appetite after a few bites of food.
		Gastritis and stomach ulcers share some of the same causes — especially H. pylori infection — and the one may be a precursor to the other.

		Atrophic gastritis was present in one patient initially; this number did not change at follow-up.
		Because of the small numbers, we cannot conclude that H. pylori infection is not associated with atrophic gastritis in the absence of acid-suppression.

	European Helicobacter Study Group
		Among 63 papers accepted (27 on pathology, gastritis, atrophic gastritis and 36 on neo-plastic diseases), seven papers were selected as oral presentations.
		The conclusion of the study was that low serum B12 and high serum homocysteine, associated with atrophic corpus gastritis, are common (prevalence 2.5%) in an elderly general population.
		Ptc was markedly reduced in atrophy and only weakly positive in IM and gastric cancer.They concluded that the decreased expression of the Shh pathway in atrophic gastritis and gastric cancer might reflect altered differentiation processes within the gastric unit and contributes to the development of gastric atrophy.

		However, this is masked by the astonishingly high prevalence of atrophic gastritis, and Helicobacter pylori infections, both of which have been found to be associated with secondary hypochlorhydria in older individuals (Goldschmiedt et al., 1991; Greenwald and Brandt, 2003).

		Chronic atrophic gastritis can be categorized as mild, moderate, or severe by estimating the thickness of the glandular portion in relation to the whole mucosal thickness.
		The Type B form restricted to the antrum is known as hypersecretory gastritis and is associated with hyperchlorhydria and duodenal peptic ulceration.
		Hemorrhagic gastritis, a life-threatening illness characterized by multiple hemorrhages throughout the mucosa, usually occurs on a background of chronic gastritis, and can be precipitated by alcoholism, anti-inflammatory agents and stress.

		Gastritis commonly refers to inflammation of the lining of the stomach, but the term is often used to cover a variety of symptoms resulting from stomach lining inflammation and symptoms of burning or discomfort.
		Gastritis should not be confused with common symptoms of upper abdominal discomfort.
		This form of nonerosive gastritis is the result of infection with Helicobacter pylori bacterium, a microorganism whose outer layer is resistant to the normal effects of stomach acid in breaking down bacteria.

		Chronic gastritis and chronic atrophic gastritis in particular are risk factors for gastric cancer.

	atrophic gastritis
		Chronic atrophic gastritis is a disorder of the stomach where gland loss and intestinal metaplasia (change in the lining of the stomach-the lining appears more like the intestine).
		Another type of chronic atrophic gastritis is called multifocal atrophic gastritis and is the predominant type in most populations at high risk of gastric cancer.
		The routine surveillance for patients with chronic atrophic gastritis in the United States is not currently recommended, since the number of diagnosed cases of gastric cancer would be very small.However, if dysplasia (glandular distortion) is encountered on tissue biopsy of the stomach close follow-up is recommended.I hope you find this information helpful.
