  • Title: Stimulated gastrinemia, parietal cell mass and stimulated acid secretion in autonomous chronic gastritis: Helicobacter pylori influence.
    Author: Testino G, Cornaggia M, Cheli R.
    Journal: Hepatogastroenterology; 1995; 42(5):650-4. PubMed ID: 8751229.
    Abstract:
    BACKGROUND/AIMS: In the present experience, an evaluation has been carried out of stimulated gastrinemia, parietal cell mass, and acid secretion in the course of a paradigmatic condition, such as autonomous chronic gastritis, in order to reveal possible changes induced by the presence of Helicobacter Pylori (HP). MATERIALS AND METHODS: We evaluated 153 patients with chronic gastritis of the antrum and/or body fundus, in different combinations not associated with peptic pathology. RESULTS: In the group of subjects with antral superficial chronic gastritis associated with normal body-fundic mucosa or with body-fundic superficial chronic gastritis, about 40% of the subjects in the HP positive group show gastrinemia values which are higher than the norm. The evaluation of parietal cell and stimulated acid secretion yielded no differences between the HP positive and HP negative groups: it emerges that these parameters vary exclusively according to the histologic state of the body-fundic mucosa. In the patients group with hypergastrinemia, the study has revealed no variations in parietal cell mass and acid secretion. CONCLUSION: Evidently the increase in gastrinemia in these subjects was not important enough to induce an increase in parietal cell mass and acid secretion. It emerges how the presence of HP does not imply substantial changes on the gastric cyto-functional parameters: these variations depend mainly on the histologic state of the gastric mucosa.
