What is the association between H. pylori and development of autoimmune disorders?

Helicobacter pylori (H. pylori) is the main cause of chronic gastritis and a major risk factor for gastric cancer. This pathogen has also been considered a potential trigger of gastric autoimmunity, and in particular of autoimmune gastritis.

Does H. pylori weaken immune system?

Chronic infection with H. pylori has significant interactions with immune system resulting in its downregulation. Role of H. pylori in pathogenesis of autoimmune diseases remains controversial with some evidence even suggesting a protective role.

Long-term infection with Helicobacter pylori could potentially lead to asymptomatic chronic gastritis, chronic dyspepsia, duodenal ulcer disease, gastric ulcer disease, or gastric malignancy, including both adenocarcinoma and B-cell lymphoma.

How does H. pylori invade the immune system?

pylori avoids innate and acquired immune response elements, uses gastric epithelial cells as mediators to manipulate host T cell responses and uses virulence factors to avoid adaptive immune responses by T cells to establish a persistent infection.

Can a stomach ulcers cause autoimmune disease?

pylori (such as H. pylori cagA positive) can increase the risk of autoimmune diseases. In addition, it was shown that infection with H. pylori can prevent the development of atrophic gastritis by stimulating inflammation in the gastric antrum.
