Treatment of Helicobacter pylori Infection 2013.

Abstract

This review summarizes important studies regarding Helicobacter pylori therapy published from April 2012 up to March 2013. To begin with, the updated European Consensus Guidelines were published last year, highlighting the role of bismuth and nonbismuth quadruple regimen as first-line treatments. Cure rates for standard triple therapy remain acceptable in quite a few settings nowadays, and some reports on innovative triple therapies look promising. One study evaluating bismuth quadruple therapy as first-line therapy was reported. Regarding nonbismuth quadruple regimens, there is a trend of superiority emerging for the "concomitant" therapy over the "sequential" regimen. "Hybrid" therapy, a combination of sequential and concomitant therapy, has also shown advantage over sequential therapy. Levofloxacin-based therapies appear to be useful and versatile in second- and third-line therapies, with interesting results for newer generation quinolones, which may partially overcome antibiotic resistance. Some promising works have been reported for bismuth-based rescue therapy, using individualized therapies upon antimicrobial information, as well as for rifabutin fourth-line therapy. Probiotics appear to have an effect in terms of reducing side effects and improving compliance, but data on improvement of eradication rates remain controversial.
