[Campylobacter pylori infection in chronic gastritis and gastric cancer]

The present paper analyses, in correlation with histologic lesions, the incidence of infection with Campylobacter pylori (CP) in patients with chronic gastritis, operated stomach, gastric neoplasm and healthy subjects. In chronic gastritis, incidence of infection with CP is 71.6%, significantly increased in comparison with the controls, in whom the positive percentage is 37.5. The most of the patients in this group suffered from superficial chronic gastritis. In the group with operated stomach, the CP infection included 48% of the patients studied; all had superficial chronic gastritis. In gastric cancer, CP bacteria appeared in 50% of cases. CP may represent a pathogenetic ring that starts the gastric process.
