Abstract

Introduction: Socioeconomic factors play an important role in the prevalence of Helicobacter pylori (HP) infection. The aim of this study is to investigate HP prevalence among symptomatic patients in the upper socioeconomic segment of the population undergoing gastroscopy in an endemic urban region.

Methodology: Over a 12-month period, data were collected from the first consecutive 1000 patients (500 from university hospital, 500 from community hospital) who had gastroscopy and HP evaluation.

Results: Overall, 211/1000 patients (21.1 %) were found to have HP in gastric biopsies. The specificity, sensitivity, positive predictive value, negative predictive value and diagnostic accuracy of rapid urease test were 87.5%, 99.7%, 99%, 96.5%, and 96.9% respectively. Atrophic gastritis, gastric and duodenal ulcers were significantly more common in HP positive patients. Age based distribution of HP prevalence: > 6 decades (15.5%), 3rd-5th decades (26.1%), < 3rd decades (10.4%).

Conclusion: In an HP endemic country, the prevalence of HP infection among symptomatic patients belonging to the upper socioeconomic segment of the population appears to be markedly lower. The lowest prevalence in young patients is expected to result in future decrease in HP prevalence.
