| Abstract | ||
| Background and aim: The Operative Link on Gastritis Assessment (OLGA) and Operative Link on Gastritis Intestinal Metaplasia Assessment (OLGIM) scores are used, in addition to the Sydney system, for chronic gastritis caused by Helicobacter pylori (H. pylori). They enable the grading of histological lesions of glandular atrophy and intestinal metaplasia, which are associated with low and high risk of neoplastic degeneration, respectively. We evaluated chronic Helicobacter pylori gastritis according to OLGA and OLGIM scores, and investigated the factors related to the occurrence of severe histological lesions. Patients and methods: We conducted an analytical cross-sectional study from January 1, 2023, to June 30, 2023. Included were adult patients of both sexes who presented with chronic Helicobacter pylori gastritis, diagnosed by histological analysis of gastric biopsies. The re-evaluation of atrophy and intestinal metaplasia of the Sydney System parameters made it possible to define OLGA and OLGIM stages, respectively. The significance threshold retained was set at p < 0.05. Results: Our study included 346 patients with a mean age of 44.4 ± 14.2 years and a sex ratio of 0.71. Lesions of glandular atrophy and intestinal metaplasia were present in the antrum in 32.4% and 12.7% of cases, respectively. Stage III disease represented 2.0% of the cases according to the OLGA score and 0.6% of the cases according to the OLGIM score. None of the patients had a stage IV disease. Conclusion: Severe histological lesions (OLGA-OLGIM III and IV) are rare, despite the high prevalence of Helicobacter pylori infection. | ||
