PIP study
Study hypothesis
1. To determine subgroups of patients with gastro-oesophageal reflux symptoms according to endoscopy and pH monitoring
2. To evaluate the differences in the subgroups of patients with Gastro-oEsophageal Reflux Disease (GERD) symptoms in:
a. duration of Proton Pump Inhibitor (PPI) treatment (four versus eight weeks)
b. inflammatory reaction
c. prevalence of Helicobacter pylori
d. occurrence of symptoms
3. To evaluate treatment of GERD patients with PPIs for four or eight weeks in order to determine the effectiveness of the PPI treatment
4. To evaluate the effect of PPI treatment on:
a. symptom relief
b. inflammatory reaction in the oesophagus
