Brief Summary

Helicobacter pylori is the main cause of chronic gastritis, peptic ulcer and gastric tumors (adenocarcinoma and lymphoma). The cure of the H. pylori infection prevents recurrence of duodenal and gastric ulcer and improves dyspepsia in a significant proportion of cases, so it is cost-effective.

Eradication therapy has changed over time. The usually recommended pattern in the consensus conferences has traditionally been triple therapy, composed by the combination of 2 antibiotics (clarithromycin plus amoxicillin or metronidazole) and a proton pump inhibitor (PPI) for 7-14 days. Recent meta-analyses have that the current global eradication rate after standard triple therapy is less than 80%. Several European studies have found even lower eradication rates, with 35-40% of cases resulting in treatment failure. Treatment failure leads to a second treatment and a new diagnostic test to confirm eradication.

Detailed Description

Justification of the study:

One of the latest therapeutic innovations is sequential therapy, introduced in Italy by Zullo et al. The drug delivery strategy involves a 5-day induction phase with dual therapy (a PPI every 12 hours and amoxicillin 1g every 12 hours), followed immediately by triple therapy for 5 days with a PPI every 12 hours, metronidazole 500 mg every 12 hours and clarithromycin 500 mg every 12 hours. Sequential therapy has proved more effectiveness than standard triple therapy for seven and ten days. In order to assess the efficacy of this new treatment in our area, over the past year we conducted a multicentre observational pilot study in routine clinical practice conditions in patients infected with H. pylori and with indications for eradication. 139 patients from 6 different centres were included. Excellent treatment compliance and minimal side effects, similar to those described with triple therapy, were shown. The results confirm similar efficacy to that obtained in previous studies and an eradication rate significantly higher than that obtained with classic triple therapy in our area.

Several previous studies have shown excellent efficacy of quadruple therapy with a PPI, amoxicillin, clarithromycin and metronidazole, administering "concomitantly" the same drugs as those of sequential therapy, but only for 5-7 days. Several studies have found a higher eradication rate of this "concomitant" therapy as compared with classic triple therapy. The results of a randomized study in which sequential and concomitant therapy were compared have recently been reported in the American Congress of Gastroenterology. Eradication and adverse events rates were similar with both treatments. This data suggest that the "sequentially"administration of these drugs probably complicated unnecessarily the treatment.

Therefore it is necessary to make a controlled clinical trial to directly compare "sequential" versus "concomitant" therapy. The results of this study will conclude which should be the first line treatment for H. pylori eradication.
