Core Tip

Core Tip: This retrospective study investigated the effects of IgG-mediated food intolerance, Helicobacter pylori (H. pylori) infection, and metabolic syndrome on reflux esophagitis. In 7954 outpatients, the prevalence of reflux esophagitis was 20.84%. Patients with IgG-mediated food intolerance and metabolic syndrome are at higher risk of developing reflux esophagitis, while patients with H. pylori infection are at lower risk. IgG-mediated food intolerance reduces the risk of reflux esophagitis pathogenesis in patients with H. pylori infection; however, metabolic syndrome increases the risk of patients with H. pylori infection developing reflux esophagitis.
