Background: In the eradication of H. pylori infection, even today, the main international guidelines recommend the triple therapy as first-line regimen, although its effectiveness is clearly decreasing. As second-line treatment, the bismuth-containing quadruple therapy is the most used regimen, although several other therapies are studied. The Italian guidelines recommend, alternatively, sequential therapy or triple therapy as first-line treatment and levofloxacin-containing triple therapy as second-line regimen. We wanted to assess the overall eradication rate of Helicobacter pylori infection in two therapeutic rounds following the Italian guidelines in clinical practice. Materials and Methods: We treated 231 consecutive Helicobacter pylori-positive patients by sequential therapy and we verified the eradication 8-10 weeks after treatment by stool antigen test. Patients positive for stool antigen test received levofloxacin-containing triple therapy, as second-line therapy, according to Italian Guidelines and they were again submitted to the fecal test 8-10 weeks after the end of treatment. Results: In the first-line regimen, we obtained an eradication rate of 92.6%, in the second-line of 75.0% and as cumulative result we achieved a 97.8% of eradication, in per-protocol analysis. Conclusions: Sequential therapy as first-line and levofloxacin-containing triple therapy as second-line represent a good combination to eradicate Helicobacter pylori infection in only two rounds.
Helicobacter pylori infection: Sequential therapy followed by levofloxacin-containing triple therapy provides a good cumulative eradication rate.
