intrinsic-factor and Gastroesophageal-Reflux

The Authors show and discuss the classification proposed till now for dividing chronic atrophic gastritis into subtypes different in hystological, functional or immunological aspects. In accordance with the more recent reports, the classification into type A, type B and type AB is accepted. Genetical (factor A) and environmental agents (alcohol, smoke, drugs) as well as immunological (parietal and gastrin cell antibodies) and functional abnormalities (duodenogastric reflux), suggested to play a role in the aetiopathogenesis of chronic atrophic gastritis, are also re-examined. Finally, dynamic aspects of chronic atrophic gastritis and its association with anemia and gastric carcinoma are widely reviewed.
