Fasting gastrin levels in serum were measured in 49 patients with different types of chronic gastritis and in matched controls. In 15 patients with established pernicious anaemia the mean (+/- S.E. of mean) level of gastrin was greatly raised (699 +/- 99 pg/ml). In 17 patients with chronic atrophic gastritis, seropositive for parietal cell antibody but with adequate vitamin-B(12) absorption, th...

BACKGROUND AND OBJECTIVE Previous small studies suggest that chronic atrophic gastritis is common in dermatitis herpetiformis (DH). We here examined the frequency and topography of chronic gastritis in 93 untreated DH subjects and in 186 controls with dyspepsia. METHODS Specimens were drawn from the gastric corpus and antrum and examined for atrophy, intestinal metaplasia, and Helicobacter py...

Atrophic gastritis is considered to be an antecedent to intestinal metaplasia and gastric cancer. A previous study identified that Helicobacter pylori was absent at the severe atrophic gastritis stage, and alterations in the gastric microbial composition resembled those in gastric cancer. To explore the role of the bacteria absence of H. pylori in gastric carcinogenesis, in the current study, w...

OBJECTIVE To study free- and protein-bound cobalamin absorption and the correlation with atrophic gastritis in healthy middle-aged and older subjects. DESIGN A cross-sectional study. PARTICIPANTS Fifty-two healthy subjects, aged 26 to 87 years, apparently free from conditions known to influence the cobalamin status. Middle-aged subjects were defined as those younger than 65 years of age (me...

This study aims to detect the mRNA of p53β and Δ133p53 isoforms in three gastric carcinoma cell lines and tissues of superficial gastritis, atrophic gastritis, gastric carcinoma, or paracancerous area. Nested reverse transcription PCR was used to detect the mRNA of p53β and Δ133p53 isoforms in tissues of superficial gastritis, chronic atrophic gastritis, gastric cancer cell lines (SGC-7901, MKN...

Gastric carcinoma was detected nine, 10, 18, and 21 years after the biopsy diagnosis of atrophic gastritis in four patients of a group of 40. The gastritis was presumed to be of the simple type. Tests of vitamin B,2 absorption in three patients gave normal results, no gastric autoantibodies were detected in the two patients tested, in all patients histological examination of the gastrectomy spe...

BACKGROUND Reflux esophagitis is inversely associated with the presence of atrophic gastritis, and endoscopic grading of atrophic gastritis correlates with histological evaluation. The aim of this study was to investigate the association of the endoscopic grade of atrophic gastritis with gastroesophageal and gastropharyngeal reflux. METHODS A total of 627 patients, who underwent endoscopy and...

BACKGROUND Atrophic body gastritis is considered the first important step in the histogenesis of gastric carcinoma, a multistep process starting from chronic gastritis and progressing through chronic atrophic gastritis, intestinal metaplasia, and dysplasia. Helicobacter pylori is involved in the induction of atrophic body gastritis, but documentation of H. pylori infection is difficult because ...

Atrophic gastritis is understood as a progressive inflammatory process of the gastric mucosa, characterized by loss glands. Helicobacter pylori infection (HP) and autoimmune are recognized most common etiological factors causing atrophic gastritis. The results retrospective analysis prevalence chronic associated with H. in patients non-cardiac cancer Bukhara city were described. In addition, an...

An immunological classification of chronic gastritis based on the detection of Helicobacter pylori (H. pylori) antibody, parietal cell antibody, intrinsic factor antibody, is reported. H. pylori chronic gastritis, slowly progresses to atrophic gastritis, in the majority of patients; in a few patients, with genetic susceptibility to form intrinsic factor antibody, it progresses to pernicious ana...
