title: [The influence of Helicobacter pylori eradication on appearance of gastro-oesophageal reflux disease].
abstract: Gastro-oesophageal reflux disease (GERD) includes wide spectrum of symptoms caused by gastric acid regurgitation through the incompetent lower oesophageal sphincter in oesophagus. Etiopathogenesis of GERD is multifactorial.
  
  
  OBJECTIVE
  to establish the relationship between Helicobacter pylori eradication and appearance or aggravating of present GERD. If this relationship exist, the aim is to estimate its level and clinical consequences.
  
  
  METHODS
  50 Helicobacter pylori positive patients with different endoscopic findings (ulcer disease, gastritis and non-ulcer dyspepsia) to whom eradication of Helicobacter pylori was done, were following next 6 months. Questionnaire, uppear GI endoscopy with verification changes of oesophagus in accordance to LA classification, histopathological examination of gastric and oesophageal mucosal biopsy specimens, and oesophageal manometry have been done to all patients. These examinations have been done before Helicobacter pylori eradication and one, three. six and none months after that.
  
  
  RESULTS
  non statistical significant difference was found among the appearance or aggravating of present GERD in all patients during the following period (Cochran Q test; p=0,408). Non statistical significant difference was found among the endoscopic types of oesophagitis (LA classification) in all patients during the following 6 months (Friedman test; p=0,058). Non statistical significant difference was found among the changes of histopathological findings on distal oesophagus, too (Friedman test; p=0,217).
  
  
  CONCLUSIONS
  Eradication od Helicobacter pylori infection does not cause the appearance or aggravating of present GERD. The presence of mildly form of GERD, or aggravating of present GERD is transitory, and haven't the statistical signification.
