Tailored Therapy for Clarithromycin-Resistant H. Pylori

Efficacy Comparison of Metronidazole-based Triple and Bismuth-based Quadruple Therapy for Clarithromycin Resistant-Helicobacter Pylori Infection: Randomized Controlled Trial

Clarithromycin-resistant H. pylori is the main cause of H. pylori eradication failure. Tailored therapy on the basis of detection of a clarithromycin resistance mutation by PCR has been studied recently, however, there have been few studies comparing treatment regimen in patient with clarithromycin-resistant H. pylori. We used sequencing-based clarithromycin resistance mutation and aimed to compare PAM (proton pump inhibitor, amoxicilline, metronidazole) regimen and PBMT (proton pump inhibitor, bismuth, metronidazole, tetracyclin) regimen in patient with clarithromycin-resistant H. pylori.
