title: Improvement of gastrointestinal quality of life scores in cases of Helicobacter pylori-positive functional dyspepsia after successful eradication therapy.
abstract: Functional dyspepsia (FD) refers to a broad range of chronic upper abdominal symptoms associated with food intake. A definitive treatment for FD has not yet been established, and the effect of Helicobacter pylori (H. pylori) eradication still remains under debate. The Gastrointestinal Symptom Rating Scale (GSRS) is a specific questionnaire for patients with gastrointestinal symptoms. The present study examined the quality of life (QOL) of patients with H. pylori-positive FD following H. pylori eradication.
  
  
  METHODS
  Sixty-eight patients with FD who gave informed consent were recruited for the study. H. pylori infection was diagnosed by the culture and histological methods, and the H. pylori eradication consisted of a 7-day course of lansoprazole, amoxicillin and clarithromycin. The overall success of the treatment was confirmed by a 13C urea breath test (UBT) conducted 3 months after the eradication. The GSRS questionnaire was administered to the patient just before the start of the eradication therapy and at 3 months after the therapy, just before the UBT was performed.
  
  
  RESULTS
  In successfully eradicated patients, the total GSRS and the abdominal pain score significantly decreased. In particular, the abdominal pain score and indigestion score were significantly decreased after successful eradication in patients with ulcer-like FD or dysmotility-like FD. Conversely, in patients in whom the eradication was unsuccessful, neither the total GSRS nor any of the individual symptom scores showed any significant change.
  
  
  CONCLUSIONS
  Successful H. pylori eradication improved the QOL of patients with FD, in particular H. pylori-positive patients with ulcer-like FD or dysmotility-like FD.
