摘要
Background: A substantial minority of patients with gastro-oesophageal reflux disease (GERD) are infected with Helicobacter pylori, but there is controversy as to whether these patients should be treated for their infection. We hypothesized that H. pylori eradication increases gastro-oesophageal acid reflux in such patients with time. Methods: Thirty-five consecutive H. pylori-infected patients (16 M and 19 F) with mild or moderate reflux oesophagitis were enrolled. Twenty-four-hour intra-oesophageal (n = 35) and intragastric (n = 12) pH-metry was recorded before and 15 months after H. Pylori eradication. Gastric biopsy specimens from the antrum and corpus were obtained from 10 consecutive patients before and 15 months after H. Pylori eradication. Results: Fifteen months after eradication of H. pylori there was a significant decrease in percentage time oesophageal pH <4 in the recumbent position only (P = 0.04). Despite a marked reduction in the severity of gastritis, there was no significant change in gastric acidity, total intra-oesophageal acid exposure or symptom score. Heartburn improved in 12, worsened in 7, and remained unchanged in 16 patients (P = 0.36) without any significant relationship to individual changes in acid exposure (P = 0.60). Conclusions: H. Pylori eradication does not increase gastric acidity or gastro-oesophageal acid reflux in patients with mild to moderate reflux oesophagitis over the first 15 months.
