Helicobacter pylori infection and atrophic gastritis.

Atrophic gastritis and Helicobacter pylori infection in outpatients referred for gastroscopy.

BACKGROUND Atrophic gastritis has been shown to be one of the long term sequelae of Helicobacter pylori infection. AIMS To determine the prevalence of atrophic gastritis in outpatients, to study the accuracy of serological methods for revealing atrophy, and to define the association of H pylori infection with atrophic gastritis in these patients. PATIENTS/METHODS A total of 207 consecutive ...

Application of serology in the diagnosis of Helicobacter pylori infection in patients with atrophic gastritis.

Positive result by serology indicates active Helicobacter pylori infection in patients with atrophic gastritis.

Patients with atrophic corpus gastritis and elevated Helicobacter pylori antibody titers but 13C-urea breath test (13C-UBT) and histology results negative for H. pylori were randomized into eradication therapy or follow-up only. Antibody levels decreased significantly in six out of seven patients in the eradication group, while in the follow-up group, the titers declined in only one out of eigh...

Western blotting of total lysate of Helicobacter pylori in cases of atrophic body gastritis.

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 ...

Long-term sequelae of Helicobacter pylori gastritis.

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...

18F-FDG uptake in the stomach on screening PET/CT: value for predicting Helicobacter pylori infection and chronic atrophic gastritis

BACKGROUND The aim of this study was to determine the value of 18F-FDG uptake on screening PET/CT images for the prediction of Helicobacter pylori (H. pylori) infection and chronic atrophic gastritis. METHODS Among subjects who underwent 18F-FDG PET/CT for cancer screening from April 2005 to November 2015, PET/CT images were analyzed in 88 subjects who had gastrointestinal fiberscopy within 6...
