D. N. CROFT, D. J. POLLOCK, AND N. F. COGHILL (London) Using a method of saline perfusion the rate of accumulation of DNA in the stomach was measured in patients with normal gastric mucosa, with pernicious anaemia, and with simple atrophic gastritis. Patients with normal mucosa, or pernicious anaemia, had low DNA rates. A majority of patients with simple atrophic gastritis had much higher value...
BACKGROUND Chronic gastritis is one of the most common findings at upper endoscopy in the general population, and chronic atrophic gastritis is epidemiologically associated with the occurrence of gastric cancer. However, the current status of diagnosis and treatment of chronic gastritis in China is unclear. METHODS A multi-center national study was performed; all patients who underwent diagno...
INTRODUCTION Atrophic gastritis is a risk factor for non-cardia gastric cancer, and gastro-oesophageal reflux disease (GORD) for oesophageal adenocarcinoma. The role of atrophic gastritis and GORD in the aetiology of adenocarcinoma of the cardia remains unclear. We have investigated the association between adenocarcinoma of the different regions of the upper gastrointestinal tract and atrophic ...
Atrophic gastritis, whether caused by Helicobacter pylori infection or as a result of an autoimmune process, is associated with corpus atrophy. However, whereas atrophic gastritis caused by H. pylori involves the antrum, the antrum is spared in autoimmune gastritis. Here, we report the use of magnifying endoscopy to identify and distinguish atrophic gastritis caused by H. pylori from autoimmune...

Background/Aims: Gastric atrophy can be diagnosed by serum pesinogen I/II ratio. The aim of this study was to investigate whether the changes of serum pepsinogen I/II ratio can be predicted by gastroscopy. Materials and Methods: Sixty healthy subjects who underwent screening for serum pepsinogen I/II levels, serum Helicobacter pylori (H. pylori) antibody, and gastroscopy for two sequential year...
INTRODUCTION The Northeastern region of Peninsular Malaysia is an area with exceptionally low prevalence for Helicobacter pylori infection. The risk of intestinal metaplasia and dysplasia in patients with chronic atrophic gastritis (CAG) and its association with Helicobacter pylori is unknown in this region. METHODS This was a cross-sectional study on gastric biopsies from 234 consecutive pat...
BACKGROUND Enzyme-linked immunosorbent assay (ELISA) is the most commonly used serologic test for Helicobacter pylori. This study aimed to investigate the effects of age and atrophic gastritis on the diagnostic accuracy of an immunoglobulin G (IgG) antibody test against H. pylori in adults. METHODS One hundred and seventy dyspeptic patients (age range, 20-70 years) were evaluated. H. pylori i...
Background: Currently, non-invasive methods for screening atrophic gastritis and gastric cancer are lacking. The purpose of this study was to evaluate the value of serological parameters including serum pepsinogen I (PGI), pepsinogen II (PGII) and pepsinogen I: II ratio for the screening atrophic gastritis and gastric cancer. Methods : The study population consisted of 132 dyspeptic patient...
Gastritis is defined as inflammation of the gastric mucosa. In histological terms, it is distinguishable into two main categories, i.e. non-atrophic and atrophic. In the gastric mucosa, atrophy is defined as the loss of appropriate glands. There are several etiological types of gastritis, their different etiology being related to different clinical manifestations and pathological features. Atro...
