Chronic Helicobacter pylori gastritis has been put forward as a risk factor for development of gastric mucosal atrophy and gastric cancer. The purpose of our study was to investigate the long-term effects of H pylori gastritis on the gastric mucosa. We prospectively studied 49 subjects negative for H pylori and 58 positive subjects for a mean follow-up of 11.5 years (range 10-13 years). Serum s...

This paper describes the incidence of positive serological tests for autoantibodies to gastric mucosal antigen and to thyroglobulin in patients with chronic gastritis, pernicious anaemia, and postgastrectomy gastritis. The results support the recent concept (British Medical Journal, 1962) that diffuse atrophic gastritis, which is the essential lesion in most cases of pernicious anaemia, may hav...

Atrophic gastritis caused by Helicobacter pylori is the precursor lesion in the development of intestinal-type gastric adenocarcinoma. In animal models, atrophic gastritis induced by Helicobacter felis has been shown to be host dependent, developing in some mouse strains and not in others. The lipopolysaccharide (LPS) of H. pylori has been suggested to play a role in the induction of gastritis....

OBJECTIVES The objective of this study was to evaluate the prevalence of atrophic gastritis and intestinal metaplasia according to gender, age and Helicobacter pylori infection in a rural population in Korea. METHODS Between April 2003 and January 2007, 713 subjects (298 men and 415 women, age range: 18-85) among the 2,161 adults who participated in a population-based survey received gastroin...

BACKGROUND Pepsinogen C (PGC) plays an important role in sustaining the cellular differentiation during the process of gastric carcinogenesis. This study aimed to assess the role of PGC tagSNPs and their interactions with Helicobacter pylori (H. pylori) in the development of gastric cancer and its precursor, atrophic gastritis. METHODS Four PGC tagSNPs (rs6941539, rs6912200, rs3789210 and rs6...

The detection of gastric premalignant lesions, atrophic gastritis, corpus atrophic gastritis, and intestinal metaplasia, using several potential markers was examined in Costa Rica. Depending on the lesion investigated, from a total of 223 dyspeptic patients, 58 (26.0%), 31 (13.9%), or 23 (10.3%) were histologically diagnosed with atrophic gastritis, corpus atrophic gastritis, or intestinal meta...

Particular alleles of the interleukin-1B (IL-1B) gene have been correlated with increased risk of atrophic gastritis and gastric cancer in the populations of East Asia and Europe. No such data exist from Peru, a developing country with a population genotypically different from others studied and with a high prevalence of Helicobacter pylori infection and gastric cancer. We conducted a case-cont...

The sequence of events in the gastric mucosa that precede the manifestation of gastric cancer has been shown to begin decades earlier. Typically, it begins with chronic non-atrophic gastritis that progresses to chronic atrophic gastritis, which may eventually lead to intestinal metaplasia, dysplasia, and finally adenocarcinoma (Kuipers, 1999). Helicobacter pylori infection is accepted as the pr...

The clinical pathological characteristics of 3969 adult patients with chronic atrophic gastritis were retrospectively studied. The positivity of intestinal metaplasia and dysplasia in atrophic gastric specimens increased with age; however, H. pylori positivity and inflammatory activity decreased significantly with increased age. H. pylori infection was present in 21.01% of chronic atrophic gast...

BACKGROUND Gastric carcinogenesis is a multifactorial, multistep process, in which chronic inflammation plays a major role. AIMS In order to ascertain whether free radical mediated oxidative DNA damage is involved in such a process, concentrations of 8-hydroxydeoxyguanosine (8OHdG), a mutagenic/carcinogenic adduct, and thiobarbituric acid reactive substances (TBARS), as an indirect measure of...
