title: Dyspepsia and Helicobacter pylori infection: a prospective multicentre observational study.
abstract: OBJECTIVE
  Dyspepsia still represents an unsolved clinical enigma.
  
  
  OBJECTIVE
  The aims of this study were to determine whether symptoms and Helicobacter pylori infection are predictors of organic disease in uninvestigated dyspepsia, and if H. pylori eradication improves symptoms in functional dyspepsia.
  
  
  METHODS
  An observational study was performed on outpatients with uninvestigated dyspepsia. Symptoms were scored and H. pylori status determined. Patients with functional dyspepsia and H. pylori infection were randomly given either a standard eradicating treatment or a 1-month course of empirical treatment. The latter was also given to functional dyspeptic patients without infection. Symptoms were re-assessed in functional dyspeptic patients at 2- and 6-month follow-up visits. Patients receiving eradicating treatment were re-tested for H. pylori at the 2 month visit.
  
  
  RESULTS
  A total of 860 patients were studied and 605 (70.3%) were affected by functional dyspepsia. H. pylori infection was diagnosed in 71.8% of patients with organic dyspepsia and in 65.0% with functional dyspepsia (p=0.053). Male sex, anaemia, smoking habit, age over 45 years, and severe epigastric pain, but not H. pylori infection, were independent predictors of organic disease. Symptoms significantly improved in most functional dyspeptic patients regardless of their H. pylori status and type of treatment.
  
  
  CONCLUSIONS
  H. pylori infection is not a strong predictor of organic disease in uninvestigated dyspepsia. H. pylori eradication is not essential to improve symptoms in functional dyspepsia.
