In an interesting Turkish retrospective study, conducted between 2012 and 2015, involving 1510 adults, Kekilli et al. tested triple therapy (lansoprazole 30 mg b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d.), bismuth group C (lansoprazole, clarithromycin, amoxicillin, and bismuth subsalicylate 524 mg b.i.d.), and bismuth group M (lansoprazole, amoxicillin, metronidazole 500 mg t.i.d., and bismuth) for 14 days as first line treatment for Helicobacter pylory infection. H. pylori eradication was achieved in (per-protocol analysis) 64.7% of the patients in the triple therapy group, 95.4% in the bismuth group C, and 93.9% in the bismuth group M. Intolerable side effects leading to interruption of therapy were rare (approximately 2–3%) and similar in the different groups.
These results are in agreement with the recently published Maastricht V Consensus Report, and confirmed that clarithromycin-based triple therapy should be abandoned when the clarithromycin resistance rate is more than 15%. In regions with high clarithromycin resistance but low-to-intermediate metronidazole resistance (<40%), 14 days bismuth quadruple therapy is advised as first line treatment.
In Turkey, the H. pylori clarithromycin resistance is 16.3–50% whereas metronidazole resistance is 39.2%.
In 2012, in Piedmont, Northern Italy, a region with the same H. pylori antibiotic resistance of Turkey, we  have prospectively evaluated the H. pylori eradication rate of 182 consecutive naive patients treated with a clarithromycin-based triple therapy: The eradication rate was 73.4%, which is considered unacceptable.
In conclusion, the study conducted by Kekilli et al. reaffirm that triple therapy now has an unacceptable eradication failure rate and it should no more be the first choice in countries with a high H. pylori resistance rate to clarithromycin. In this context, now is the era of bismuth-based quadruple therapy as first line treatment. When available, this could be prescribed as the new formulation with bismuth, metronidazole, and tetracycline contained in a single capsule (three-in-one).
