Abstract

Helicobacter pylori (H. pylori) is one of the most common infections worldwide. According to modern ideas, it is the main cause of a number of diseases of the stomach and duodenum (peptic ulcer, chronic gastritis, MALT lymphoma) and the leading risk factor for stomach cancer. In the hospital therapy clinic of the Kirov Military Medical Academy, we observed 118 patients. The study groups included patients with various types of chronic gastritis (atrophic and non-atrophic). The patients were comparable in gender and age. Infection H. pylori was verified in 22 patients (68.8%) suffering from chronic non-atrophic gastritis and in 34 patients (37.2%) suffering from chronic atrophic gastritis. In the course of the study, the relationship between the contamination of H. pylori and the presence of dysregenerative changes in the gastric mucosa was evaluated. It was found that H. pylori infection does not significantly affect the development and progression of atrophy in the mucous membrane of the antrum of the stomach. Also, no convincing data on the effect of H. pylori on dysregenerative processes (intestinal metaplasia and dysplasia) in the gastric mucosa. At the same time, the presence of pathogenicity factors H. pylori Vac A and Cag A significantly affects the progression of atrophic changes in the gastric mucosa. At the stage of formed atrophy, the intensity of H. pylori invasion is significantly reduced.
