Association of autoimmune type atrophic corpus gastritis with Helicobacter pylori infection.

Aim: To study the association between Helicobacter pylori (H. pylori) infection and autoimmune type atrophic gastritis.

Methods: Twenty-three patients with different grades of atrophic gastritis were analysed using enzyme immunoassay-based serology, immunoblot-based serology, and histology to reveal a past or a present H.

Enhanced systemic matrix metalloproteinase response in Helicobacter pylori gastritis.

Background: Helicobacter pylori causes chronic gastritis, peptic ulcer disease, and is the most important risk factor for non-cardia gastric cancer, and has been shown to upregulate matrix metalloproteinases (MMPs) in infected gastric mucosa. MMPs are proteolytic enzymes regulated by tissue inhibitors of metalloproteinases (TIMPs).

Aims: We set up this study to find out whether H.
