Helicobacter pylori Isolate from Endoscopy Examined Patients in Bahir Dar, North West Ethiopia Helicobacter pylori Isolate from Endoscopy Examined Patients in Bahir Dar, North West Ethiopia

Background: The Helicobacter pylori infection is highly prevalent throughout the world and causes gastric-associated diseases. Its microbial niche is the stomach, where it causes different abnormalities while being observed. As a result, the current study sought to determine the magnitude and effects of Helicobacter pylori in patients who underwent endoscopic examination. Method: An institution-based cross-sectional study was conducted from January to May 2019 at endoscopy service-providing health institutions. Socio-demographic and clinical data were collected using a pretested, structured questionnaire. Gastric biopsies were collected according to the Sydney protocol during endoscopic procedures and immediately inoculated into brain-heart infusion broth. Data were entered and analyzed using SPSS version 23. Result:  Among the 135 study participants, 59.3% were males and 40.7% were females, with a mean age of 45 years old. The proportion of Helicobacter pylori isolated was 17.8% (24/135). The majority of isolates (71% of 17/24) were from males, while only 29% of 7/24) were from females. Isolation of Helicobacter pylori was significantly associated with a high salt intake habit [AOR = 3.3, 95% CI = (1.5, 10.8), P = 0.04] and the presence of a duodenal ulcer [AOR = 3.8, 95% CI = (1.2, 11.9), P = 0.02. The highest proportion of Helicobacter pylori had been observed in patients with atrophic pan gastritis. Conclusion: The prevalence of Helicobacter pylori isolated from the study participants was relatively lower. High salt intake and the presence of duodenal ulcers are significantly associated with Helicobacter pylori infection.
