Introduction: Chronic gastritis is a group of conditions commonly characterized by stomach lining inflammation. The study aims to investigate the clinical and pathological aspects that play a role in its development. Additionally, the study examines the use of CD117 as an immunohistochemistry marker in evaluating mast cell density (MCD). Methods: This retrospective, cross-sectional study was conducted in Iraqi Kurdistan with a sample size of 380 patients. Patient data included gastritis type, neutrophil infiltration severity, mononuclear cell infiltration within the lamina propria, intestinal metaplasia, and glandular atrophy, which were categorized and given a score. The CD117 level was identified using an anti-human rabbit polyclonal antibody. Results: A statistically significant association was revealed between Helicobacter pylori-mediated gastritis and non-specific gastritis with age, activity, H. pylori and MCD, dysplasia, and malignancy. Meanwhile, no association was found with gender, inflammatory infiltrate, intestinal metaplasia, and glandular atrophy. C-Kit exhibited a marked increase in MCD in patients with H. pylori-mediated gastritis, intestinal metaplasia, atrophy, and gastric carcinoma. However, a significant decrease in MCD was observed on repeating endoscopy evaluations for patients after treatment. Conclusion: Regions that exhibit severe inflammation, metaplasia, atrophy, and carcinoma demonstrated an increase in MCD with H. pylori-mediated gastritis. A detailed investigation in clinical practice to screen early diagnosis and treatment needs to be performed in high H. pylori prevalence.
