BACKGROUND: Autoimmune gastritis (AIG) leads to increased gastrin (G) levels due to hypo-achlorhydria, providing proliferative stimuli on the gastric mucosa.
AIMS: To evaluate the incidence and characteristics of gastric polyps in AIG patients across six tertiary centers in Italy.
METHODS: A multicentric, cross-sectional study enrolled patients with AIG diagnosed from January 2000 to June 2023, who underwent at least one endoscopy. Data on demographics, clinical history, biochemical profiles, and endoscopic and histopathological findings were systematically collected.
RESULTS: Among 612 AIG patients followed for a median of 4 years, 222 (36.3 %) developed at least one gastric polyp. Of these, 214 were non-endocrine lesions detected in 162 patients, including 151 inflammatory (70.5 %), 29 adenomatous (13.6 %), 18 fundic gland polyps (8.4 %), 13 adenocarcinomas (6.1 %), and one MALT lymphoma. Additionally, 108 patients had gastric neuroendocrine neoplasms (gNENs), with 48 also having non-endocrine polyps. Older age and higher gastrin and chromogranin A levels were associated with polyp occurrence. No differences in OLGA/OLGIM stages or Helicobacter pylori status were noted among patients with and without lesions.
CONCLUSION: This large multicentric study underscores the substantial occurrence of gastric polyps in AIG patients, including notable rates of gNENs and adenocarcinomas, emphasizing the importance of proactive endoscopic surveillance and histopathological examination for effective management.
