title: Characteristics of patients with erosive and nonerosive GERD in high-Helicobacter-pylori prevalence region.
abstract: It is still not known whether there are differences between erosive and nonerosive GERD. The aim of the present study is to evaluate the prevalence of Helicobacter pylori (HP) infection, and other differences between erosive and nonerosive gastroesophageal reflux disease (NERD) patients. One-hundred and four consecutive GERD patients (mean age: 41.6 +/- 12.3 years) were interviewed, endoscoped and tested for HP. Erosive GERD was defined according to the Los Angeles classification. Patients who had no erosions in the esophagus but complained of heartburn or/and acid regurgitation at least twice a week and for whom these symptoms had a negative impact on daily activities were considered to be NERD patients. Erosive GERD was identified in 53 (51%) patients (mean age: 41.0 +/- 12.7 years) and NERD in 51 (49.0%) patients (mean age: 42.2 +/- 11.9 years). HP infection was found in 32 (60.4%) erosive GERD patients, and 41 (80.4%) NERD patients, P < 0.05. Multivariate analysis revealed that there were two statistically significant prediction factors for NERD: female sex with odds ratio (OR) of 6.34 (95% CI: 2.41-16.64; P = 0.0002) and HP infection with odds ratio (OR) of 3.28 (95% CI: 1.26-8.58; P = 0.015). The presence of HP and female sex are found to be statistically significant predictors of NERD.
