BACKGROUND/AIMS Intestinal metaplasia (IM) is a common finding at the oesophagogastric junction, but the aetiopathogenesis of the different IM subtypes-that is, incomplete IM (specialised columnar epithelium, SCE) and complete IM- and their associations with gastro-oesophageal reflux disease and Helicobacter pylori gastritis are unclear. METHODS 1058 consecutive dyspeptic patients undergoing ...
To determine the effect of varying degrees of gastritis on the distribution of immunoreactive gastrin cells 38 partial gastrectomy specimens have been studied. Routinely stained histological sections of mucosa were compared with serial and adjacent sections stained by specific immunohistochemistry using peroxidase and fluorescent techniques. While chronic superficial gastritis had no obvious ef...
Eosinophils of the gastrointestinal tract are involved in the host immune response that occurs in the presence of the pathogens in the digestive lumen, taking part in maintaining the homeostasis of the gastrointestinal epithelium. Their involvement in inflammatory processes of chronic gastritis is less known. In our study, we identified the presence of eosinophils in chorion gastric mucosa (lam...
BACKGROUND Gastric premalignant conditions, atrophic gastritis (AG) and intestinal metaplasia (IM) are characterized by an increase of proliferation and a reduction of apoptosis in epithelial cells. The epithelial cell kinetics in AG and IM in gastric mucosa adjacent to gastric cancer is still unclear. The aim of this study was to evaluate the epithelial cell turnover and expression of prolifer...
BACKGROUND A few studies have indicated inverse relationships between serum ghrelin and gastric and esophageal cancers but those associations have been restricted to specific populations, including smokers and overweight individuals. We examined the association between ghrelin and gastroesophageal cancers and atrophic gastritis in a population-based setting. METHODS In total 220 gastroesophag...
The present study aims to explore the clinical value of pepsinogen II and gastritis detection. Firstly, serum expressions in patients with Helicobacter pylori-caused gastritis, gastric ulcer atrophic were detected using enzyme-linked immunosorbent assay, followed by statistical analysis. In comparison normal group, levels increased above groups (p<0.01). Next, positive cut-off for detecting was...
Gastric cancer is one of the most common neoplastic diseases in developed Western countries, and is characterized by a poor prognosis when diagnosed at a late stage [1]. Atrophic gastritis and gastric intestinal metaplasia (GIM) are well-known risk factors for the development of gastric cancer. For this reason, endoscopy with multiple biopsies is recommended in patients with atrophic gastritis ...
Subclinical vitamin B12 and folate deficiency is common in the elderly. The clinical significance remains unresolved. There is not a universally accepted set of laboratory criteria for diagnosis, however subclinical deficiency is important to diagnose since it is easy to treat. Currently available measures of vitamin concentrations are, except in pronounced deficiency, unreliable. Plasma tHcy a...
