ABSTRACT Helicobacter pylori has a centeral role in the pathogensis of chronic Active gastritis. Infection usually occures during childhood and last for a lifetime. Infectious is a worldwide phenomen but its prevalence is varied. Chronic (Atrophic) gastritis and intestinal metaplasia was accepted as a precursor of intestinal type gastric Carcinoma. Now more searches in the world doing ab...
To determine whether there is a relationship between the presence of H pylori and the various subtypes of intestinal metaplasia in the gastric antrum, 2274 antral gastroscopic biopsies from 533 patients were examined. H pylori was found in 289 patients. Intestinal metaplasia in general was found in 135 patients. Type I intestinal metaplasia was found in 133 patients (98.5%), type II in 106 pati...
Gastric intestinal metaplasia, an intermediate lesion in the development of intestinal-type gastric cancer, is observed in the milieu of long standing non-atrophic gastritis and atrophic gastritis. Most patients with intestinal metaplasia remain asymptomatic unless cobalamin deficiency occurs secondary to loss of glands (that produce intrinsic factor and acid). Genetic events that predispose to...
Adenocarcinoma of the distal esophagus and gastroesophageal junction are believed to arise in Barrett's esophagus with intestinal metaplasia. Whether adenocarcinoma can arise in columnar lined esophagus without intestinal metaplasia is in doubt. Whether adenocarcinoma of the gastric cardia arises in intestinal metaplasia of the gastric cardia is also in doubt. We aim to evaluate the relationshi...
BACKGROUND & AIMS Over the past few decades, the incidence of adenocarcinomas of the gastroesophageal junction has rapidly increased. Barrett's esophagus is a risk factor for esophageal adenocarcinoma, but the role of intestinal metaplasia of the gastric cardia as a precursor in cardia-related cancer is controversial. The aims of the present study were to examine the prevalence of intestinal me...
CONTEXT Intestinal metaplasia of the stomach is a lesion in which metaplasia of gastric epithelial cells occurs for an intestinal phenotype. Gastric intestinal metaplasia is a lesion associated with an increase in the risk of gastric carcinoma development. Epidemiologic studies indicate a relation between dietary habits and stomach cancer development, some habits increasing the risk for it, and...
Background—It has been suggested that the subtyping of intestinal metaplasia in the stomach is useful in stratifying patients with regard to risk of developing gastric cancer. Aim—To determine whether subtyping intestinal metaplasia provided useful information regarding the natural history of intestinal metaplasia. Methods—The study used large cup gastric biopsy specimens from predetermined loc...
aim : this study used the olga system to characterize the histology pattern of gastritis in dyspeptic outpatients with a mean age of 45 years from regions with different gastric cancer risks. background : several classification systems have been purposed for understanding the status of the gastric mucosa. currently, the sydney system is the most widely employed. nevertheless, the applicabili...
To study the relationship between intestinal metaplasia and Helicobacter pylori infection, 2274 gastroscopic antral biopsies taken from 533 patients were examined. Overall, intestinal metaplasia was found in 135 patients (25.3%) and H pylori in 289 patients (54.2%). The prevalence of intestinal metaplasia and H pylori was age related, being more common in patients greater than or equal to 50 ye...
Intestinal metaplasia is a well-established premalignant condition of the stomach that is characterized by mucin carbohydrate modifications defined by histochemical methods. The purpose of the present study was to see whether the expression of mucin core proteins was modified in the different types of intestinal metaplasia and to evaluate the putative usefulness of mucins as "molecular markers"...
