Title: [Influence of Helicobacter pylori on gastric secretion. Study on variously associated gastric body, fundus and antrum chronic gastritis].
Abstract: Among the various themes related to Helicobacter pylori (HP) which is still a subject of discussion, there is the possible influence of this bacterium on gastric secretory physiology. In the present study, an evaluation has been carried out of stimulated gastrinemia, stimulated acid secretion and total peptic activity in gastric juice in the course of a paradigmatic condition, as autonomous chronic gastritis, in order to reveal possible modifications induced by the HP infection. In cases of HP positive chronic superficial antral gastritis associated either with normal body-fundic mucosa or with superficial gastritis, there is a significant increase of stimulated gastrinemia in comparison to HP negative groups and controls. In the course of body-fundic atrophic and preatrophic chronic gastritis associated either with antral superficial chronic gastritis or with antral atrophic gastritis, there are no statistically significant differences between HP positive and HP negative subjects. As regards acid and pepsin secretion no significant differences emerge in any group between HP positive and HP negative subjects. In the HP positive subjects with antral superficial gastritis and higher gastrin values the study of acid and pepsin secretion has yielded no significant variations. From the results of this study it emerges how gastric secretory parameters vary exclusively according to the histologic state of gastric mucosa. Therefore, the lesion action of HP may mainly be attributed to a direct action, rather than to substantial gastric secretory changes.
