Overview
Brief Summary
Due to the high rate of resistance to clarithromycin in our area the investigators proposed an study to assess the need of antibiogram previous to the empirical OCA 10 treatment, in order to improve the rate of eradication.
Detailed Description
Usefulness of antimicrobial susceptibility in the eradication of Helicobacter pylori PURPOSE Background: * The rate of eradication of Helicobacter pylori with standard triple therapy (OCA: omeprazole + clarithromycin + amoxicillin) in our area is less than the expected according to the III Maastricht III consensus. However, the current guidelines recommend the use of this therapy. * According to the Maastricht III consensus, in populations with high rates of clarithromycin resistance (15-20%) another therapy should be considered, or alternatively, testing antimicrobial susceptibility of the H. pylori prior to treatment. Objectives: * To clarify the real rate of eradication with OCA therapy with and without antimicrobial susceptibility in our area (with high rate of resistance to clarythromycin). * To study which is the diagnostic-therapeutic strategy more cost-effective for the treatment of H. pylori. Design: * Participants will be screened with a full medical history. * Participants will aleatory receive OCA therapy empirically, or after antimicrobial susceptibility test if there is no resistance to clarythromycin, for ten days. * In all cases the eradication of H. pylori will be checked by 13C urea breath test (UBT) in 8 weeks after the therapy have been finished. * All the adverse event of the therapy will be reported.

Outcomes
Primary Outcomes
Number of patients in whom Helicobacter pylori was eradicated.
Time Frame: 9 months
The investigators will measure the rate of eradication in each gruop after OCA treatment. One group receive OCA without antibiogram and the other one after checking the sensitivity to clarithromycin.
Secondary Outcomes
- Number of patient with adverse event(9 months)
- Cost of the eradication of Helicobacter Pylori in each group.(9 months)
