Prevalence of Helicobacter pylori infection among patients with dyspepsia and other gastrointestinal diseases in King Abdulaziz Specialized Hospital in Taif

Introduction: To estimate the prevalence of H. pylori in patients with dyspepsia as well as the prevalence of cancerous and precancerous nonmalignant lesions in patients with H. pylori. Methods: A retrospective cohort study has been conducted at King Abdulaziz Specialist Hospital (KAASH), Ministry of Health (MOH) in Taif city in the Western province of Saudi Arabia among patients who underwent endoscopy between July 2019 and July 2021. Data were collected from the endoscopy log book and consisted of four sections; demographic data (age and gender), presenting symptoms and indications of endoscopy, endoscopic findings, and histopathological findings in endoscopic biopsies. Results: The study included 680 patients. Their age ranged between 12 and 97 years with an arithmetic mean of 40.9 years and a standard deviation of 16.4 years. The prevalence of dyspepsia was 45.9% while that of H. pylori was 32.5%. The prevalence of H. pylori among patients with dyspepsia was 30.1% compared with 34.5% among those without dyspepsia, P > 0.05. The prevalence rates of H. pylori among male and female patients were 32.3% and 32.7%, respectively, P > 0.05. The prevalence rate of H. pylori was highest among patients aged between 41 and 60 years (38.7%) and lowest among those aged over 60 years (19.5%), P = 0.005. Active chronic gastritis was reported among almost two-thirds (65.6%) of patients with H. pylori compared with only 9.8% of those without H. pylori, P < 0.001. Conclusion: The H. pylori was a common health problem among patients suffering from dyspepsia, however, its prevalence was relatively lower than other rates reported from other developing countries.
