Chronic gastritis is an inflammation of the gastric mucosa and has multiple etiologies. Here we discuss the pathological alterations induced by Helicobacter pylori (HP) leading to chronic gastritis and the epigenetic bases underlying these changes. We review the histology of the normal gastric mucosa and overview the role of HP in the multistep cascade of GC. We attempt to define the role of th...

CD95 (Fas/APO-1)-mediated apoptosis plays an important role in immunological regulation and is related to the pathogenesis of autoimmune diseases. Immunoexpression of CD95 has been reported to frequently occur in low grade non-Hodgkin lymphomas, especially of post-germinal center histogenesis, among which those originating in mucosa-associated lymphoid tissue (MALT lymphomas). However, there is...

Prostaglandins are widely used in the prevention and healing of non-steroidal anti-inflammatory drug (NSAID) induced gastric and duodenal ulcers, but their longterm effect on the human gastric mucosa is unknown. This study assessed the effect of coadministration of prostaglandins with NSAIDs on the histology of the gastroduodenal mucosa. Histological appearances (using the Sydney system) of gas...

Increased epithelial cell proliferation is associated with an increased risk of adenocarcinoma and is associated with Helicobacter pylori infection. The aim of this study was to assess both gastric epithelial cell proliferation and the influence of H pylori infection on cell kinetics in the progression from normal mucosa to gastric carcinoma. One hundred and forty four subjects were assigned to...

The advent of the fibreoptic gastroscope with biopsy facilities has provided the means of obtaining biopsy specimens under direct vision from any part of the stomach. This creates new opportunities for the study of chronic gastritis, and, in particular, its evolution, topographical location, and causal relationships. On the basis of an experience with more than 2,500 biopsy specimens we have ou...

INTRODUCTION Many clinicians consider chronic gastritis to be equivalent to Helicobacter pylori infection. However, it is known that there are numerous other causes of the condition. AIM Determination of the incidence of gastritis in patients with dyspepsia referred for diagnostic endoscopy of the upper part of the digestive tract, identification of the parts of the stomach most frequently af...

Since the Consensus on chronic gastritis in China was developed in September 2006 in Shanghai, much progress has been made in the diagnosis and treatment of chronic gastritis, including the Operative Link for Gastritis Assessment (OLGA), European Consensus On management of precancerous conditions of gastric cancer, and Maastricht-IV consensus. Therefore, the “2012 Chinese National Consensus Mee...
