Structural Characteristics of Gastric Cell Populations in Chronic Gastritis and Chronic Hepatitis under Conditions of Helicobacter pylori Persistence

Helicobacter pylori persistence in patients with chronic gastritis is associated with a complex of nonspecific structural reactions, the type of these reactions correlates with the severity of infection: catarrhal fibrotic changes in the gastric mucosa predominate in cases with manifest colonization, while the absence of H. pylori is associated with predominance of fibrotic process. Analysis of the incidence of some pathomorphological phenomena (degeneration, atrophy, metaplasia, and dysplasia of the surface epithelium) shows no relationship between the presence of H. pylori and colonization intensity. In all patients with chronic hepatitis, the gastric mucosa is involved in the pathological process; fibrosis (gastropathy) was the most common process. No appreciable correlations between the structural changes and hepatitis activity and the presence of H. pylori were detected.
