Study summary

To simultaneously compare the efficacies of 7-day triple, 10-day sequential and 7-day quadruple therapies for H. pylori infection in Taiwan. Consecutive H. pylori-infected patients were randomly assigned to a 7-day standard triple therapy (pantoprazole, clarithromycin, and amoxicillin for 7 days), a 10-day sequential therapy (pantoprazole and amoxicillin for 5 days, followed by pantoprazole, clarithromycin and metronidazole for a further 5 days) or a 7-day quadruple therapy (pantoprazole, clarithromycin, amoxicillin and metronidazole for 7 days). The end point is to evaluate the effectiveness of Helicobacter pylori eradication rates between three groups.

Read the detailed description

The purpose of this study is to compare the effectiveness of three H. pylori eradication regimens: 7-day standard triple therapy (pantoprazole, clarithromycin, and amoxicillin for 7 days), 10-day sequential therapy (pantoprazole and amoxicillin for 5 days, followed by pantoprazole, clarithromycin and metronidazole for a further 5 days) and 7-day quadruple therapy (pantoprazole, clarithromycin, amoxicillin and metronidazole for 7 days) in Taiwan.

A total of 306 subjects are enrolled into this study.

H. pylori-infected patients are randomized to a 7-day standard triple therapy, a 10-day sequential therapy, or a 7-day quadruple therapy. Eradication efficacy is assessed by a follow-up endoscopy with rapid urease test and histological examination eight weeks after the H. pylori therapy. The eradication rates of three groups will be compared.
