A novel endoscopic artificial intelligence system to assist in the diagnosis of autoimmune gastritis: a multicenter study

Endoscopy
Background  Autoimmune gastritis (AIG), distinct from Helicobacter pylori-associated atrophic gastritis (HpAG), is underdiagnosed due to limited awareness. This multicenter study aimed to develop a novel endoscopic artificial intelligence (AI) system for

Iron and Vitamin B12 Deficiency in Patients with Autoimmune Gastritis and Helicobacter pylori Gastritis: Results from a Prospective Multicenter Study

Digestive Diseases
Introduction: Iron and vitamin B12 deficiencies are common in patients with atrophic gastritis, but there are limited data on the prevalence of these deficiencies in different types of atrophic gastritis.

Atrophic autoimmune gastritis: ‘a muddled or misguided core concept compromises our overall comprehension of the problem’

Gut, 2023
We thank Lahner et al for their interest in our study: considering their extensive experience in the field of gastric autoimmunity, their contribution is particularly welcome.

Autoimmune Atrophic Gastritis With Hypergastrinemia

Southern Medical Journal, 1976
Elevation in fasting serum gastrin levels was found in three patients being evaluated for persistent upper abdominal pain without radiographic evidence of peptic ulcer disease. Fiberoptic endoscopy of the upper gastrointestinal tract in each patient revealed characteristic changes of chronic atrophic gastritis.

Autoimmune gastritis may be less susceptible to cancer development than Helicobacter pylori-related gastritis based on histological analysis

Gut, 2023
We read with great interest the recent publication by Rugge et al, in which the authors conducted a cohort study to evaluate the association between autoimmune gastritis (AIG) and gastric cancer (GC).

Gastric cancer risk in autoimmune gastritis: evidence versus opinion

Gut, 2023
We thank Waldum for his interest in our study on autoimmune gastritis, reflected in his letter ‘The conclusion that autoimmune gastritis does not predispose to gastric cancer (GC) is unproven.’ 2 Science rarely allows conclusive statements. However, some

Review of autoimmune metaplastic atrophic gastritis

Gastrointestinal Endoscopy, 2013
SUMMARY The clinical goal of managing AMAG is to identifydysplastic or malignant lesions of the stomach as well as toensure the proper management of vitamin B 12 deficiencyto prevent the hematologic and neurologic adverse eventsof pernicious anemia. The testing algorithms for diagnos-ing pernicious anemia may not always apply to the diag-nosis of early ...

Cutting Edge Issues in Autoimmune Gastritis

Clinical Reviews in Allergy & Immunology, 2010
Autoimmune gastritis is the outcome of a pathological CD4 T cell-mediated autoimmune response directed against the gastric H/K-ATPase. Silent initially, the gastric lesion becomes manifest in humans by the development of megaloblastic pernicious anemia arising from vitamin B12 deficiency.
