title: [Helicobacter pylori gastritis: assessment of OLGA and OLGIM staging systems].
abstract: Helicobacter pylori (H pylori) gastritis presents a risk of cancer related to atrophy and intestinal metaplasia. Two recent classifications OLGA (Operative Link on Gastritis Assessment) and OLGIM (Operative Link on Gastritic Intestinal Metaplasia assessment) have been proposed to identify high-risk forms (stages III and IV). The aim of this study is to evaluate the OLGA and OLGIM staging systems in H pylori gastritis. A descriptive study of 100 cases of chronic H pylori gastritis was performed. The revaluation of Sydney System parameters of atrophy and intestinal metaplasia, of gastric antrum and corpus, allowed identifying respectively the stages of OLGA and OLGIM systems. The progressive risk of our H pylori gastritis was 6% according to OLGA staging and 7% according to OLGIM staging. Significant correlation was revealed between age and OLGA staging. High-risk gastritis according to OLGIM staging was significantly associated with moderate to severe atrophy. High-risk forms according to OLGA staging were associated in 80% of the cases to intestinal metaplasia. OLGA and OLGIM systems showed a highly significant positive correlation between them with a mismatch at 5% for H pylori gastritis. The OLGA and OLGIM staging systems in addition to Sydney System, allow selection of high risk forms of chronic gastritis requiring accurate observation.
