Core Tip

Core Tip: Decreased success eradication rates of Helicobacter pylori (H. pylori) have received much attention in recent years, mainly due to the increasing resistance to antibiotics. Focus has begun to be placed on the efficacy of antibiotic susceptibility-guided eradication. This study revealed that the secondary resistance rate of H. pylori to clarithromycin and levofloxacin in Province Liaoning, was higher than the national average. Antibiotic susceptibility-guided eradication therapy is more effective than empiric treatment. It provided a reference for eradication therapy in regions in the northeast of China.
