BACKGROUND The prevalence of Helicobacter pylori (H. pylori) infection is high, but the incidence of gastric cancer is low in natives of Bangladesh. The gastric mucosa was observed in Bangladeshi patients to investigate the differences between Bangladeshis and Japanese. MATERIALS AND METHODS The study involved 418 Bangladeshi and 2356 Japanese patients with abdominal complaints who underwent ...

UNLABELLED Backgroud: Helicobacter pylori (Hp) rarely proliferates in patients with fundic gland polyps (FGPs). We recently found that FGPs express lysozyme, one of the natural defence substances against infection. We aimed to assess the degree of lysozyme expression in a cohort of consecutive FGPs. MATERIALS AND METHODS A total of 153 gastric biopsies were investigated: 93 with FGPs, 30 with...

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...

Emphysematous gastritis is a severe and rare form of gastritis with characteristic findings of intramural gas in the stomach. It is an acute life-threatening condition resulting from gas-producing microorganisms invading the stomach wall. Early diagnosis and initiation of treatment with bowel rest, hydration, and intravenous broad-spectrum antibiotics is imperative for an effective outcome. Sur...

The frequency of gastric Crohn's disease has been considered low. This study was undertaken to determine the prevalence of chronic gastritis and Helicobacter pylori infection in patients with Crohn's disease. Oesophagogastroduodenoscopy was performed on 62 consecutive patients suffering from ileocolonic Crohn's disease. Biopsy specimens from the antrum and corpus were processed for both histolo...

AIMS To determine the prevalence of Helicobacter pylori in five main nationality groups with gastric ulcer, duodenal ulcer, and non-ulcer dyspepsia; and to determine the histopathological types of gastritis and assess the graded variables of Helicobacter associated gastritis. METHODS Gastric antral and corpus biopsy specimens from 437 patients were examined for the prevalence of H pylori, 337...

SNP rs2294008 in Prostate Stem Cell Antigen (PSCA) and decreased PSCA expression are associated with gastric cancer. The objective of this study is to investigate the role of rs2294008 and PSCA expression in the gastritis-gastric cancer carcinogenic pathway. We conducted a case-control association study of H. pylori-infected gastritis and gastric cancer. rs2294008 was associated with the progre...

The pathogenesis of autoimmune gastritis is the result of lymphocyte infiltration of the gastric mucosa, however, the events leading to the selective extravasation of autoreactive lymphocytes are unclear. Here we have examined the expression of adhesion molecules in the gastric mucosa of BALB/c mice with neonatal thymectomy-induced gastritis. The overall area of vascular endothelium was not sig...

The effect of graded doses of pentagastrin on the gastric scretion of acid was compared in patients with and without gastritis. Biopsies were taken from the body of the stomach. Ten subjects had normal gastric mucosa, eight had superficial gastritis, and 10 atrophic gastritis. Pentagastrin in a dose of 1.5 mug/kg/hr elicited a near maximal HCl response from both the normal gastric mucosa and th...

An investigation of 102 men comprising alcoholics, patients with non-ulcer dyspepsia, and healthy controls is reported. It demonstrates that alcohol is a cause of chronic gastritis and the severity of the mucosal lesion is directly related to the duration of excess drinking. Contrary to popular belief, chronic gastritis does not give rise to symptoms. The effect of alcohol on the gastric mucosa...
