Task: Answer Verification
Input (English): Question: Is helicobacter pylori infection involved in the pathogenesis of either erosive or non-erosive gastro-oesophageal reflux disease?
Answer: H. pylori infection had the same prevalence in reflux patients and in controls. It did not affect oesophageal acid exposure, as there was no difference between H. pylori-positive and H. pylori-negative individuals. The high prevalence of mild body gastritis in H. pylori-positive patients suggests that H. pylori eradication is unlikely to lead to gastric functional recovery, which might precipitate or worsen symptoms and lesions in patients with gastro-oesophageal reflux disease.
Output (English): no
