Abstract
Background
The association between H. pylori (Helicobacter pylori) infection and gastroesophageal reflux disease (GERD) is a complex and confusing subject. The aim of this study was to evaluate the association between helicobacter pylori infection and erosive gastroesophageal reflux disease.
Method
In a cross-sectional study, all patients referred for endoscopy due to dyspepsia were enrolled. The diagnosis of erosive GERD was made by endoscopy. Patients with normal esophagus were selected as comparison group. Random gastric biopsies were taken from all participants to diagnose H. pylori infection.
Result
In total, 1916 patients were included in this study, of whom 45.6% had GERD. The mean age (SD) was 42.95 (16.32). Overall, 1442 (75.3%) patients were positive for H. pylori infection. The frequency of H. pylori infection in mild GERD patients was higher than the severe GERD, but this difference was not significant (P = 0.214). Except for sociodemographic status (P < 0.001), other variables including gender, age, ethnicity, body mass index (BMI), smoking, and presence of hiatus hernia in patients had no significant association with the frequency of H. pylori infection. According to Robust Poisson regression models analysis, the association of H. pylori (PR 1.026; 95% CI 0.990–1.064; P = 0.158) and sociodemographic status were not significantly different between the two groups. But smoking, increased BMI, older age, presence of hiatus hernia, and peptic ulcer diseases were significantly associated with GERD compared with the non-GERD group.
Conclusion
In our results, there was no association between H. pylori infection and erosive GERD. Further studies are recommended.
