Despite H. pylori infecting an estimated 50% of the global population,there is no universally effective regimen in everyday clinical practice. The current European Helicobacter Study Group Guidelines for the first line empirical treatment of the H. pylori infection propose a variety of treatment strategies, as optimal treatment of H. pylori infection requires careful attention to local antibiotic resistance and eradication patterns. Most recently, the Toronto Consensus for the Treatment of Helicobacter pylori Infection in Adults strongly recommended that all H. pylori eradication regimens now be given for 14 days. Recommended first-line strategies include concomitant nonbismuth quadruple therapy (proton pump inhibitor [PPI] + amoxicillin + metronidazole + clarithromycin [PAMC]) and traditional bismuth quadruple therapy (PPI + bismuth + metronidazole + tetracycline [PBMT]).The aforementioned statement by an international working group of specialists chosen by the Canadian Association of Gastroenterology is of the outmost importance, especially in countries with increased antibiotic resistance, like Greece, with resistance rates >20% to clarithromycin and >40% to metronidazole.
