The aim of this study was to determine the prevalence of gastritis in upper endoscopies performed for clinical signs suggestive of gastritis among 100 patients in a tropical country. Chronic gastritis (CG) was present among 81%, including CG due to Helicobacter pylori (n = 61, 75.3%), reactive CG (n = 14), and autoimmune CG (n = 6). The gastritis was located in the stomach antrum (55.7%, n = 40), fundus (3.3%, n = 2), or both (41% n = 25). Median age at diagnosis was 35 years (14/80). This CG was associated with signs of stomach activity (27.9%, n = 17), atrophy (13.1%, n = 8), metaplasia (9.8%, n = 6), and dysplasia (8.2%, n = 5). The 14 patients with reactive CG had a mean age of 31 years and all were coffee-drinkers. This CG was not associated with precancerous lesions. Autoimmune CG, present in 6% of the population, was diagnosed at a mean age of 55 years (range: 45; 67). These involved fundal atrophy with metaplasia and were associated with dysplastic lesions (66.7% n = 4).
