Background: The long-term outcomes of Helicobacter pylori infection ultimately depend on the distribution and extent of gastritis. Three main types of gastritis phenotypes which include pangastritis, antral-predominant gastritis, and corpus-predominant gastritis have been observed. Corpus predominant gastritis is more common in the parts of Asia with a high prevalence of gastric adenocarcinoma. This study was conducted to determine the prevalence of H. pylori-associated gastritis phenotypes in a South-western Nigerian population, a sub-Saharan African population. Materials and Methods: The study was a cross-sectional prospective study which included 267 dyspeptic patients who had esophagogastroduodenoscopy at a tertiary health institution in South-west Nigeria. Five gastric biopsies were taken from each subject, and standard histologic examination was performed on the specimens. Both biopsy sampling and histologic examination followed the Updated Sydney System recommendations. The data generated were statistically analyzed. Continuous variables were presented as means ± standard deviation, whereas associations between the categorical variables were determined by the Pearson Chi-square test or Fisher's exact test. P ≤ 0.05 was considered statistically significant. Results: The mean age was 46.1 (±15.4) years while the age range was 16–84 years. There were 160 (59.9%) female and 107 (40.1%) male participants. All participants had histological gastritis, whereas 79 (29.6%) were positive for H. pylori by histology. H. pylori infection was significantly associated with peptic ulcer disease. Among those who had H. pylori infection, 51 (64.6%) had pangastritis, 26 (32.9%) had antral-predominant gastritis, while 2 (2.5%) had corpus-predominant gastritis. The relationship between H. pylori infection and the gastritis phenotypes showed no statistical significance. Conclusion: The prevalence of corpus predominant gastritis was low in our study population.
