Distribución de estadios de OLGA y OLGIM según edad y estado del Helicobacter pylori en un hospital público nivel III en Lima, Perú

Abstract

Introduction. The operative link for gastritis assessment (OLGA) and the operative link on gastric intestinal metaplasia assessment (OLGIM) staging systems have been suggested to provide risk of assessment for gastric cancer. Objective. To evaluate the distribution of OLGA and OLGIM staging by age and Helicobacter pylori status. Material and methods. We studied 197 subjects undergoing elective upper gastrointestinal endoscopy. The presence of the H. pylori and histological changes were evaluated using the updated Sydney system. Stages III and IV of OLGA/OLGIM were considered high risk stages. Results. The H. pylori rate was 56.85% (112/197). High-risk OLGA/OLGIM cases were rare: 7/112 (6.5%) cases of OLGA in the H. pylori positive group and 6/85 (7%) in the H. pylori negative group; 5 (4.4%) cases of OLGIM in the H. pylori positive and 6 (7%) in the H. pylori negative. The proportion of advanced stages of OLGA and OLGIM increased with age (p < 0.001). High-risk OLGA was not found before age 40 regardless of the presence of H. pylori, but increased to 16.2%, 10.3%, 17.3% and 40.8% in subjects in the fourth, fifth, sixth and seventh decade of life respectively. The OLGIM high risk showed a similar trend: 0% before 40 years and up to 22.6% in people of 70 years. Conclusions. High-risk OLGA/OLGIM cases are infrequent before age 40 and increase significantly with age. No relation was found with the presence of the H. pylori. According to these protocols, only a fifth of the patients would strictly require endoscopic control.
