title: [Prevalence of Helicobacter pylori infection among children and youth with acid gastroesophageal reflux].
abstract: OBJECTIVE
  The aim of the study was to estimate the prevalence of Helicobacter pylori infection in patients with acid gastroesophageal reflux. PATIENTS NAD METHODS: Analysis of medical records of 160 children and youth admitted to the hospital between October 2003 and December 2004 was performed. All of these patients were diagnosed for acid gastroesophageal reflux due to clinical features and results of oesophageal pH-metry. During routine diagnostic procedures of abdominal pain, vomiting, nausea and other non-specific symptoms, endoscopy of upper gastrointestinal tract was simultaneously performed. Helicobacter pylori infection among analysed patients was diagnosed due to histopathological studies of specimens sampled during endoscopy and positive urease test.
  
  
  RESULTS
  Analysed group included 75 girls and 85 boys between 12 month old and 18 years old (mean age 8.47). Helicobacter pylori infection was observed in 29 patients (18.1%) of 160 analysed cases. Mean age of patients with H. pylori infection was 11.83 years, whereas mean age of patients without H. pylori infection was 7.72 years. Oesophagitis was presented in 28 (17.4%) of all patients. In the group with H. pylori infection oesophagitis was observed only in 4 patients (13,8%). In the group without H. pylori infection oesophagitis was presented in 24 patients (18,3%).
  
  
  CONCLUSIONS
  1. Prevalence of Helicobacter pylori infection among patients with acid gastroesophageal reflux was lower than prevalence of infection in children and youth population of Kujawsko-Pomorski region. 2. Helicobacter pylori infection among children and youth with acid gastroesophageal reflux doesn't influence the prevalence of oesophagitis.
