[Tailored therapy in treatment of infectionbasedon clarithromycinsensitivity].

To compare eradication rates and compliance of patients with Helicobacter pylori()infection based on clarithromycin sensitivity. From July 2015 to January 2018,patients with infection in Peking university people's hospital were randomly assignedto a 14-day treatment with clarithromycin quadruple therapy versus tailored quadruple therapy for a prospective study. In the group of tailored therapy, medications were adjusted based on clarithromycin sensitivity. In the control group, all patients were given proton pump inhibitors (PPI), amoxicillin, clarithomycin and bismuth. Eradication status was assessed 4 weeks after treatment withurea breath test. The eradication rate were higher in the tailor therapy group than that in the control group in intention-to-treat[77.8% vs 65.3%,(0.001)] and per,protocol analyses [86.4% vs 70.2%,(0.001)], the differences between the two groups were statistically significant.The incidence of compliance between the two groups were also comparable. The tailored therapy basedon clarithromycinsensitivity has a better eradication efficacy and a higher eradication ratesin the patients with infection.
