Background: Helicobacter pylori infection of the gastric mucosa is the most important aetiologic agent identified to cause chronic gastritis with consequences ranging from acute ulceration to the development of debilitating gastric cancer. Histopathologic characterisation of the disease progression from gastric biopsies is frequently required. Objectives: To determine the histopathologic pattern of gastric biopsies categorised chronic gastritis using updated Sydney classification and determined the role of Helicobacter pylori in chronic gastritis in our centre. Methodology: A retrospective study of all the gastric biopsies received in the department of Histopathology, Usmanu Danfodio University Teaching Hospital, and Sokoto between the years 2011-2020. Formalin fixed, paraffin embedded tissue blocks and slides stained with routine, special and immunohistochemical stains were used. Microscopic features detailing different pathologies were analysed and chronic gastritis were classified based on updated Sydney classification. Information on age, sex and duration of disease was retrieved from request cards and case folders. Collected data analyzed using SPSS version 20. Results: There were 252 gastric biopsies received, 137 male and 115 female patients and a ratio of 1.2:1. Their ages ranged from 16 to 82 years and peak in the 6th decade of life with a mean age of 46.5 years. The most common diagnosis was chronic gastritis and constitutes 85.5% (215 cases), followed by adenocarcinoma (10.3%), gastrointestinal stromal tumour (2.4%) and gastric ulcer (2.0%). Among chronic gastritis, 47.4% were H. pylori associated. Moderate to severe activity and inflammation were seen in 45.6% and 48.4% respectively. Mucosal atrophy (Atrophic Gastritis) was seen 81.4% while 19.5% show complete or incomplete intestinal metaplasia. Conclusion: Helicobacter pylori organism was the common cause of gastric morbidity in our environment, causing chronic gastritis with predominantly mild to moderate grade of inflammation, mucosal atrophy, activity and organisms colonisation.
