Prevalence of Helicobacter pylori infection in dyspeptic patients presenting to a tertiary care center of a developing country: a cross-sectional study

Abstract

Background: Among the various causes for dyspepsia in patients presenting to the gastroenterology department, Helicobacter pylori is the most common etiological agents. Here, we explore the prevalence of Helicobacter pylori infection, particularly, in dyspeptic patients and different endoscopic findings in such patients. Methods: We conducted a simple observational study in the gastroenterology department of a tertiary care center of Nepal. The Helicobacter pylori was detected using rapid urease test and endoscopic findings were collected from gastroduodenoscopy unit. The obtained data was analyzed using Statistical Package for Social Sciences (IBM-SPSS), version 22. Results: The overall prevalence of Helicobacter pylori infection in dyspeptic patients in our center was found to be 0.329 (0.259 – 0.406) at 95% Confidence Interval (CI). There was significant association of Helicobacter pylori infection with alcohol history (12 [52.17] vs 44 [29.93], p = 0.035) and endoscopic findings of duodenal ulcer (3, 100%) followed by gastritis (29, 50.88%). Conclusions: Amidst various etiology for dyspepsia, Helicobacter pylori was still prevalent at our center. However, considering the variability of its prevalence due to factors like alcohol history, more comprehensive studies are needed to estimate actual proportion in patients presenting with dyspeptic symptoms.
