Is intestinal metaplasia of the stomach reversible?
Intestinal metaplasia (IM) of the stomach is a risk factor in developing intestinal-type gastric cancer and hence the question of reversibility is vital. There is emerging epidemiological evidence that with long term follow up, IM may be reversible although a combination of antioxidant agents and eradication of H pylori may be necessary to achieve this. The pathogenesis of IM is currently being...
متن کاملMethod to quantitate intestinal metaplasia of stomach by image analysis.
With the aid of an image quantifier, the distribution of histochemically labelled (alcian blue, pH 2.5) mucin-producing goblet cells was recorded from a gastrectomy specimen with a peptic ulcer to determine the degree of metaplasia. Of 254 measurements made, 130 were in the antrum and 124 in the fundic area. The areas occupied by cells positive for alcian blue were 7.5 (SD 9.89)% in the antral ...
متن کاملSTOMACH Pericryptal fibroblast sheath in intestinal metaplasia and gastric carcinoma
Background and aims: In the progression of chronic gastritis, gastric mucosal cells deviate from the normal pathway of gastric differentiation to an intestinal phenotype which is closely related to gastric carcinoma. However, to date, it has not been elucidated whether the intestinal metaplasia is merely a change in the epithelium or whether the underlying mesenchyme also changes from gastric t...
متن کاملIntestinal Stem Cell Markers in the Intestinal Metaplasia of Stomach and Barrett’s Esophagus
Gastric intestinal metaplasia (IM) is a highly prevalent preneoplastic lesion; however, the molecular mechanisms regulating its development remain unclear. We have previously shown that a population of cells expressing the intestinal stem cell (ISC) marker LGR5 increases remarkably in IM. In this study, we further investigated the molecular characteristics of these LGR5+ cells in IM by examinin...
متن کاملCDX2 autoregulation in human intestinal metaplasia of the stomach: impact on the stability of the phenotype
BACKGROUND AND AIMS Intestinal metaplasia (IM) is a gastric preneoplastic lesion that appears following Helicobacter pylori infection and confers an increased risk for development of cancer. It is induced by gastric expression of the intestine-specific transcription factor CDX2. The regulatory mechanisms involved in triggering and maintaining gastric CDX2 expression have not been fully elucidat...
