Atrophic Autoimmune Gastritis: Manifestations and Clinicopathologic Associations in a Large United States Cohort

Atrophic autoimmune gastritis (AIG) is uncommon and most series include few patients. An accurate diagnosis rests on adequate gastric biopsy sampling (rarely done); thus, controls have often been subjects in whom AIG was excluded based on insufficient sampling.

H. pylori infection was unrecognized until 1985–1990, and most studies on AIG have been carried out before that time. Therefore, they may include large numbers of patients with H. pylori gastritis.
