Safra reflüsü bulunan ve bulunmayan gastrit hastalarında gastrik mukozal atrofi, intestinal metaplazi ve Helicobacter pylori durumu: Safra iyi mi kötü mü?

Abstract

Background and Aims: To investigate the relation between bile reflux and gastric mucosal atrophy, intestinal metaplasia, and Helicobacter pylori status in patients with gastritis. Materials and Methods: A total of 217 patients (mean ± SD; age: 33.2±7.9 years; 51.2% males) with gastritis were divided into two groups: patients with intragastric bile reflux (n = 134; confirmed by pathology in 20 patients) and without bile reflux (control group; n = 83). The status of Helicobacter pylori and presence of intestinal metaplasia and gastric atrophy were evaluated with respect to the presence of bile reflux. Results: A positive Helicobacter pylori status, intestinal metaplasia, and gastric atrophy were observed in 85 (39.2%), 72 (33.2%), and 66 (30.4%) patients, respectively. No significant difference was noted between patients with gastritis with or without bile reflux in terms of a positive Helicobacter pylori status (38.8% vs. 45.8%), intestinal metaplasia (32.8% vs. 33.7%), and gastric atrophy (30.6% vs. 30.1%). However, the pathological confirmation of bile reflux gastritis was associated with a significantly lower rate of Helicobacter pylori positivity (0.0% vs. 45.6%; p = 0.001), intestinal metaplasia (5.0% vs. 37.7%; p = 0.009), and gastric atrophy (0.0% vs. 36.0%; p = 0.003). In patients with bile reflux (n = 134), the intestinal metaplasia and gastric mucosal atrophy rates were similar with respect to the H. pylori status. Conclusion: The rates of Helicobacter pylori positivity, intestinal metaplasia, and gastric atrophy were similar in patients with gastritis with or without bile reflux. However, the frequency of Helicobacter pylori, intestinal metaplasia, and gastric mucosal atrophy was lower in patients with pathologically confirmed biliary gastritis.
