AI Article Synopsis

  • A study assessed atrophic gastritis severity using the OLGA staging system in 163 H. pylori-positive patients, including those with gastric cancers, atrophic gastritis, and ulcers.
  • Results showed that 84% of gastric cancer patients had severe stages (III or IV), indicating a higher risk associated with cancer.
  • The OLGA system is user-friendly and effectively highlights the severity of atrophic gastritis, making it a valuable tool for gastroenterologists.

Article Abstract

Background: An international group of gastroenterologists and pathologists (Operative Link for Gastritis Assessment (OLGA)) proposed the staging system of atrophy. The aim of this study was to assess the severity of atrophic gastritis using the OLGA system.

Materials And Methods: The subjects comprised 163 H. pylori-positive patients: 18 with early gastric cancers of the intestinal type (GC), 55 with atrophic gastritis (AG), 49 with gastric ulcers or scars (GU), and 41 with duodenal ulcers or scars (DU). Biopsies were taken from the lesser and greater curvatures of the antrum and middle body. The OLGA gastritis stage (0-IV) (the severity and topography of atrophy) was obtained by combining antral with body atrophy scores. The gastritis grade (the severity and topography of inflammation) was obtained by combining antral and body inflammation scores.

Results: Most (84%) of patients with GC showed stage III or IV. Gastritis stages were significantly higher in patients with GC than in those with AG, GU, and DU. Gastritis stage became higher with age. Gastritis grades were slightly higher in patients with AG than in others.

Conclusions: Our results indicate that higher stages are found in patients with GC using the OLGA staging system and that the high risk of GC can be recognized. It is simple to use and useful for the assessment of the severity of atrophic gastritis.
