Introduction: Helicobacter pylori infection has a high prevalence and distribution worldwide. Due
to its association with the development of gastric adenocarcinoma, updates on its prevalence are of
interest to the internist or gastroenterologist and policymaking. This study measured the prevalence of H. pylori and evaluated its association with endoscopic and histopathological findings in adults with an indica- tion for upper GI endoscopy (EGD).
Materials and methods: This analytical cohort study describes the prevalence of H. pylori and assesses risk factors associated with this infection in adult patients undergoing outpatient EGD for any medical in- dication in the endoscopy unit of a quaternary care university hospital between June and December 2020. Endoscopic and histopathological findings and the pre- valence of H. pylori are described. To explore the risk factors, the chi-square (χ2) test was used to evaluate differences in proportions and the Student’s
t and Mann- Whitney U tests for continuous variables according to their distribution.
Results: 613 patients met the selection criteria and were included in the analysis. The most frequent indication for EGD was dyspepsia. The prevalence of H. pylori was 38.5% (95% confidence interval [CI]:
34.7-42.4%).
Conclusion: H. pylori is a topic of great interest in gastrointestinal pathologies. The endoscopic search should take place in the antrum and body. Its presence was most common in patients with a normal esophagus, follicular nodular gastritis, duodenal ulcer, and acute inflammation upon the histological stud complement the local epidemiological behavior.
