Context/Objective: Few studies have been carried out in a country with high endemicity for Helicobacter pylori (H. pylori) infection in Sub-Saharan Africa looking for the association of intestinal metaplasia (IM) with chronic gastritis. We hypothesize that IM is correlated with the intensity of H. pylori infection in a country with high endemicity, Ivory Coast. The objective of this study was to determine the prevalence of intestinal metaplasia in chronic H. pylori gastritis in Ivory Coast. Methods: This was a prospective, cross-sectional, multicenter study, carried out over a period of 5 months, in the reference hospital centers of Abidjan, specialized in Gastroenterology. All patients who had undergone Gastroscopy with biopsies according to the criteria of the Sydney System for the anatomopathological study, those with chronic gastritis and/or H. pylori intestinal metaplasia on histology and in whom all the parameters of the Sydney system classification had been well informed. The quantitative variables were expressed by their means accompanied by their standard deviations and the qualitative variables by their numbers and percentages. Chi-square and Fischer tests were used to look for associations between variables. The significance level was set at 5%. Results: 152 patients were retained. The mean age was 44.9 ± 12.9 years. The prevalence of intestinal metaplasia was 11.8%. In univariate analysis, no significant association was found between clinical and pathological sociodemographic factors (age, sex, ethnicity, educational level, profession) and intestinal metaplasia in chronic Helicobacter pylori gastric cases. In multivariate analysis we found that prolonged use of Proton Pump Inhibitors (PPIs) and a history of Gastroesophageal Reflux Disease (GERD) were significantly associated with the absence of IM. Conclusion: Chronic H. pylori gastritis is the main risk factor for intestinal metaplasia. Prolonged use of PPIs and a history of GERD were significantly identified as factors that would protect against intestinal metaplasia.
