Evaluación para comparar dos esquemas de terapia estándar (7 frente a 10 días) contra el Helicobacter pylori, con seguimiento clínico a 1 año Randomized study of seven days of standard treatment for Helicobacter Pylori vs. ten days of standard treatment for Helicobacter Pylori with one year follow-ups of patients

Background: The increasing resistance of H pylori to antibiotics has led to failures of eradication treatment. For this reason we intend to modify both the duration of treatment and the regime of antibiotics. Methods: After random allocation, the standard treatment with omeprazole 20 mg orally every 12 hours, amoxicillin 1 g VO every 12 hours and clarithromycin 500 mg orally every 12 hours for 7 days (group 1) was compared with the same antibiotic regime over 10 days (group 2). Patients had either non-ulcer dyspepsia (NUD) or ulcer dyspepsia (UD). Effectiveness of eradication was evaluated with breathe tests. A year later, clinical responses to each therapy were compared for patients with NUD and DU. The tolerance to therapy was also evaluated for each group. Results: 149 patients were randomly assigned to group 1 and 144 patients to group 2. The eradication rate as measured by ITT analysis was 67.8% in group 1 and 74.3% in group 2 (p = 0.24). It was 72.1% and
