Background:
Helicobacter pylori has been implicated in the aetiopathogenesis of peptic ulcer but data on the effect of infection by this organism on gastric acid secretion are equivocal. We, therefore, examined the effect of the presence of Helicobacter pylori in the antrum and body of the stomach on acid secretion.
Methods:
We used the augmented histamine test and intragastric titration in three groups of patients. In one group Helicobacter pylori was present in both the antrum and body of the stomach, in the second it was present in the antrum but not the body, and in the third the organism was absent.
Results:
There were no significant differences in acid secretion between these three groups.
Conclusion:
The presence of Helicobacter pylori in the mucosa of the gastric antrum and body has no effect on acid secretion.

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...

Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
