Definition

Autoimmune gastritis is an immune-mediated gastritis, and in its development, anti-parietal cell and anti-intrinsic factor antibodies are involved. There is typical loss of oxyntic cells in the gastric corpus and fundus. Autoimmune gastritis is characterized by hypochlorhydria or achlorhydria, hypergastrinemia, low pepsinogen I/pepsinogen II ratio, and vitamin B12 deficiency that can lead to pernicious anemia. The declining incidence of Helicobacter pylori gastritis parallels a growing clinical focus on autoimmune gastritis.

Hypochlorhydria results from loss of oxyntic mucosa and possibly from the disruption of normal parietal cell maturation. This can already occur in patients with a large number of preserved parietal cells, suggesting that there may be a role for anti-proton pump antibodies or inhibitory lymphokines released by...
