title: The effect of Helicobacter pylori eradication on gastroesophageal reflux disease.
abstract: BACKGROUND
  The effect of Helicobacter pylori (H. pylori) eradication on gastroesophageal reflux disease is controversial. We aimed to investigate the effect of H. pylori eradication in this group of patients.
  
  
  METHODS
  Thirty-four consecutive patients with H. pylori infection and reflux esophagitis (grade 1 or 2) were enrolled into the study. Twenty-four hour intra-esophageal pH recording and esophageal manometry were performed before and 3 months after eradication of H. pylori, which was achieved using lansoprazole 30 mg b.i.d., amoxycillin 1 g b.i.d., and clarithromycin 500 mg b.i.d. for 14 days. H. pylori was evaluated in biopsy specimens taken from the antrum and corpus by rapid urease test and by histopathologic examination before and 3 months after eradication.
  
  
  RESULTS
  Eighteen patients (11 men and 7 women, median age 42 years) completed the study. Three months after the treatment, there was no significant change in any of the 24-hour esophageal pH recording parameters and mean lower esophageal sphincter resting pressure (P > 0.05). The percentage of total time esophageal pH <4 increased in 10 patients, and decreased in 8 patients. There was a significant decrease in the scores of heartburn and regurgitation (P < 0.01). Esophagitis persisted in 16 patients and disappeared in 2 patients. Esophagitis score decreased in 6 patients, and did not change in 12 patients (P < 0.05).
  
  
  CONCLUSIONS
  H. pylori eradication does not have any effect on gastroesophageal acid reflux in patients with reflux esophagitis 3 months after eradication, but significant improvement is achieved in some reflux associated symptoms.
