Core Tip
Core tip: A total 680 patients who were infected with Helicobacter pylori (H. pylori) were divided into 4 groups and each group was treated with a different eradication therapy. The eradication rates were 76.2%, 84.2%, 84.4% and 94.4% in the rabeprazole, amoxicillin and clarithromycin (PAC) group, the rabeprazole, amoxicillin and metronidazole group, the sequential group and the concomitant group. Comparing concomitant therapy and PAC therapy, the number needed to treat was 5.49. The eradication rate was 84.4% for the second-line therapy and 42.9% for the third-line therapy. The study was designed due to the high prevalence of H. pylori and gastric cancer and the recent marked increase in clarithromycin resistance.
