A reliable method for the simultaneous identification of H pylori and gastric metaplasia in the duodenum.
While an association of Helicobacter pylori infection with duodenal mucosa gastric metaplasia has been described, the details and extent of the interaction are lacking. One of the limiting factors has been the lack of a staining technique that allows simultaneous visualisation of the bacteria and gastric metaplasia in the duodenum. This report describes a new stain that allows the simultaneous ...
متن کاملGastric metaplasia and Campylobacter pylori infection of duodenum in patients with chronic renal failure.
Duodenal biopsy specimens from 80 patients with chronic renal failure, who were undergoing haemodialysis, were examined by light microscopy for evidence of inflammation, gastric metaplasia, and Campylobacter pylori infection. Chronic duodenitis was present in 47 (59%) of patients, of whom only seven (9%) showed evidence of active inflammation. Gastric metaplasia was present in 50 (62.5%) of pat...
متن کاملCircadian gastric acidity in Helicobacter pylori positive ulcer patients with and without gastric metaplasia in the duodenum.
BACKGROUND The presence of gastric metaplasia allows helicobacter pylori to colonise the duodenum and this condition is thought to be acquired as a response to acid hypersecretion. This functional disorder, however, is present only in a subgroup of duodenal ulcer patients and, in addition, surface gastric metaplasia has been frequently found in the proximal duodenum of normal subjects and patie...
متن کاملEffect of Helicobacter pylori eradication on gastric metaplasia of the duodenum.
Helicobacter pylori associated duodenal ulcers occur in patches of gastric metaplasia. The pathogenesis of gastric metaplasia is unclear, but it has been produced in experimental animals by acute injury and has been shown to be present to a greater extent of H pylori positive subjects. This study aimed to discover if gastric metaplasia regressed with eradication of H pylori or healing of duoden...
متن کاملGastric Epithelium in the Duodenum.
It has been found that a ;gastric' type of epithelium tends to develop in the first part of the duodenum in patients with duodenal ulceration and is found in the second part of the duodenum in a patient with the Zollinger-Ellison syndrome. It is likely that ;gastric' epithelium appears when the duodenal acidity is high and it is resistant to ulceration.
