 Type A gastritis is an autoimmune gastritis that shows“reverse atrophy,”i.e., gastric body dominant atrophy. To diagnose“reverse atrophy,”careful attention must be paid to the prepyloric non-atrophic mucosa near the pyloric ring on endoscopic examination. Hypergastrinemia and positive antibodies to parietal cells and intrinsic factors are characteristics of type A gastritis. Pernicious anemia is the end stage of type A gastritis ; this disease is occasionally accompanied by iron deficiency anemia, type 1 diabetes mellitus, and autoimmune thyroiditis. Although hyperplastic polyps, neuroendocrine tumors, and gastric cancers are detected in some cases, various findings are observed depending on the stage of the disease. In the near future, more patients will be diagnosed with type A gastritis in the D group using the ABC screening method.
