A double-blind clinical trial investigating if a sub-group of functional dyspeptic patients without any use of NSAID or gastric erosions could have a better evolution of their dyspeptic symptoms after Helicobacter eradication than the placebo control group
Objective: investigate if a sub-group of functional dyspeptic patients without any use of NSAID or gastric erosions could have a better evolution of their dyspeptic symptoms after Helicobacter eradication than the placebo control group
Design: A randomized double-blind placebo controlled clinical trial
Inclusion Criteria: Patients with more than 18 years, Functional dyspepsia accordingly Rome III criteria, Helicobacter pylori infection by two diagnostic tests
Exclusion Criteria: No concordance with informed consent; Pregnant woman or breast feeding or no trust anticonceptional method; Structural gastrointestinal abnormalities except gastritis, duodenitis or hiatal hernia; Previous treatment for Helicobacter pylori infection; Previous surgery on esophagus, stomach or duodenum; Hypersensitivity to the drugs in study; Proton pump inhibitor use in the previous 15 days; H2-antagonists use in the previous 07 days; Antibiotics use in the previous 30 days; Patients unable to answer the study questionnaires; Alcohol abuse; Drug use; Serious comorbidities; Biliary colic; Irritable bowel syndrome; Gastroesophageal Reflux Disease
Interventions: amoxicillin, clarythromycin, omeprazole for 10 days
Control: Placebo
Outcomes:
Primary: Proportion of patients with 50% reduction of baseline symptoms score measured by the validated Porto Alegre Dyspeptic Symptoms Questionnaire Secondary: Proportion of patients with 100% reduction of baseline symptoms score measured by the validated Porto Alegre Dyspeptic Symptoms Questionnaire; Need of rescue medication; Median difference of score between groups; Mean SF-36 scores evolution between groups; Lost of productivity measured by WPAI between groups
Visits: screening, baseline, 4, 8, 12 months
Endoscopic evaluation: screening, 12 months
Helicobacter detection methods: urease, histology (3 pathologists) performed at screening and 12 months
