Abstract
Today, pathologies of the stomach and duodenum occupy a leading
place among pathologies of the gastrointestinal tract in children (1,2). Chronic lesions of
the stomach account for 70-75% of pathologies of the gastrointestinal tract. Currently,
on average, more than half of people worldwide suffer from chronic gastritis. Helicobacter
pylori, an infection in childhood, is the main cause of chronic gastritis, the microbial
origin of which is the key to understanding the strange epidemiology and course of the
disease. Prolonged and aggressive inflammation during gastritis over time (years and
decades) leads to destruction (atrophic gastritis) of the gastric mucosa. Currently, the
importance of gastritis as a serious disease is largely underestimated, although the role
of gastritis in the pathogenesis of gastric ulcers and gastric cancer is obvious [3].
