Autoimmune gastritis: long-term natural history in naïve Helicobacter pylori-negative patients

Gut, 2022
Objective Autoimmune gastritis (AIG) is an immunomediated disease targeting parietal cells, eventually resulting in oxyntic-restricted atrophy. This long-term follow-up study aimed at elucidating the natural history, histological phenotype(s), and ...

Autoimmune atrophic gastritis in systemic sclerosis

BMJ Case Reports, 2021
Systemic sclerosis (SSc) is a rare connective tissue disorder with a complex pathogenesis involving vascular dysfunction, small vessel proliferation as well as alterations of innate and adaptive immunity. Gastrointestinal (GI) involvement in SSc is almost universal and affects nearly 90% of the patients.

Polyautoimmunity in autoimmune gastritis

European Journal of Internal Medicine, 2016
Autoimmune gastritis may be associated with other organ-specific autoimmune disorders, but the prevalence of this association is not entirely quantified. The aims of this study were to investigate the prevalence of autoimmune disorders and evaluate the factors that might affect this association in patients with autoimmune gastritis.A total of 320 ...

Clue of Diagnosis for Autoimmune Gastritis

Digestion, 2021
<b><i>Background:</i></b> The diagnostic clues for autoimmune gastritis (AIG) can be classified into 2 categories: endoscopic findings and pathological diagnosis. We believe that research on the AIG detection rate by endoscopists could provide a better understanding of the diagnosis of AIG.

Incomplete Intestinal Metaplasia Is Rare in Autoimmune Gastritis

Digestive Diseases, 2023
Background: Incomplete intestinal metaplasia (IM) is reportedly associated with higher gastric cancer (GC) risk than its complete variant. AGA Guidelines recommend including IM subtyping in routine pathology reports. This study assesses the prevalence of

Autoimmune atrophic gastritis—pathogenesis, pathology and management

Nature Reviews Gastroenterology and Hepatology, 2013
Autoimmune gastritis is a chronic progressive inflammatory condition that results in the replacement of the parietal cell mass by atrophic and metaplastic mucosa. A complex interaction of autoantibodies against the parietal cell proton pump and sensitized T cells progressively destroy the parietal cells, inducing hypochlorhydria and then achlorhydria ...

Risk Factors Analysis and Predictive Model Construction for Autoimmune Gastritis: A Nationwide Multicenter Case–Control Study in China

Journal of Gastroenterology and Hepatology
Here, we ascertained the clinical characteristics of Chinese patients with autoimmune gastritis (AIG) and determined the correlation of dietary and lifestyle factors with AIG occurrence and development to establish a noninvasive predictive model for AIG.
