Although H. pylori infection can cause gastrointestinal metaplasia, its eradication does not reverse the process. [1] Bile reflux is an additional pathogenic factor in gastrointestinal metaplasia that can continuously irritate the gastric mucosa. Bile acids in refluxed fluid are widely reported to be associated with gastrointesinal metaplasia ...
It can be caused by persistent infection with Helicobacter pylori, or can be autoimmune in origin. Those with autoimmune atrophic gastritis ( Type A gastritis ) are statistically more likely to develop gastric carcinoma (a form of stomach cancer ), Hashimoto's thyroiditis , and achlorhydria .
Intestinal metaplasia typically begins in response to chronic mucosal injury in the antrum and may extend to the body. Gastric mucosa cells change to resemble intestinal mucosa and may even assume absorptive characteristics. Intestinal metaplasia is classified histologically as complete or incomplete. With complete metaplasia, gastric mucosa is ...
This includes patients diagnosed with gastric adenocarcinoma (especially those with early-stage disease), patients found to have atrophic gastritis or intestinal metaplasia, as well as first-degree relatives of patients with gastric adenocarcinoma since the relatives themselves are at increased risk of gastric cancer partly due to the ...
Micrograph showing apocrine metaplasia of the breast with typical features [3] H&E stain. Barrett's esophagus is an abnormal change in the cells of the lower esophagus, thought to be caused by damage from chronic stomach acid exposure. The following table lists some common tissues susceptible to metaplasia, and the stimuli that can cause the ...
The most common example of metaplasia is Barrett's esophagus, when the non-keratinizing squamous epithelium of the esophagus undergoes metaplasia to become mucinous columnar cells, ultimately protecting the esophagus from acid reflux originating in the stomach. If stress persists, metaplasia can progress to dysplasia and eventually carcinoma ...
[1] [2] [3] Rothia bacteria can cause disease in humans and immunosuppressed humans. [4] [5] Rothia is prevalent in human saliva and it produces enterobactin. Rothia is also prevalent in the human gut and can cause the emergence of gastric atrophy and intestinal metaplasia. [6] [7]
Owing to the causal relationship between H. pylori infection and gastric MALT lymphoma, identification of the infection is imperative. Histological examination of GI biopsies yields a sensitivity of 95% with five biopsies, [7] but these should be from sites uninvolved by lymphoma and the identification of the organism may be compromised by areas of extensive intestinal metaplasia.
