title: [Long-term course of reflux symptoms following Helicobacter pylori eradication].
abstract: OBJECTIVE
  Conflicting data regarding new onset or deterioration of gastroesophageal reflux disease (GORD) following eradication of Helicobacter pylori infection have been reported. Successful eradication therapy may influence gastric acid output. The study aimed to to investigate whether patients with pre-existing GORD or peptic ulcer disease may experience deterioration of GORD.
  
  
  METHODS
  75 consecutive patients of a prospective longitudinal study (median age 66 years, n = 45 males) had received successful H. pylori eradication therapy because of the following main diagnosis: peptic ulcer (n = 37), GORD (n = 16), functional dyspepsia (n = 22). Two to three years later, they had an interview regarding the course of their dyspeptic and reflux symptoms. Negative H. pylori status at present was confirmed by (13)C-urea breath test in all patients. Ten patients were excluded because of proton pump inhibitor treatment.
  
  
  RESULTS
  Patients with deterioration of GORD (new onset or increasing reflux symptoms) were found significantly more frequently in the group with functional dyspepsia (36 %) compared to pre-existing GORD (16 %) or peptic ulcer disease (5 %). Improvement of pre-existing reflux complaints were reported mostly by patients with peptic ulcer disease. There was no significant impact of initial reflux manifestations like reflux symptoms or reflux oesophagitis on the course.
  
  
  CONCLUSIONS
  During long-term follow-up after H. pylori eradication, patients experience improvement as frequently as deterioration of reflux symptoms. There is a tendency towards improvement of reflux symptoms if peptic ulcer disease had been the indication for eradication, but towards deterioration in patients with initial functional dyspepsia. A clinical relevant prediction, however, is not feasible.
