Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Approximately 50% of people in the world are infected with H. pylori, and its eradication rate fail to exceed 80% and even fails into an unacceptable range.Various risk factors for infection include lower socioeconomic status, younger age, and geographic location.In the present study, investigators aimed to perform a prevalence survey about risk factors for H. pylori infection.To obtain the higher eradication of H. pylori and find out the relevance between the diverse infection and clinical drug focused on refractory H. pylori infection.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Successful treatment

Group Type EXPERIMENTAL

The eradication times of the patients

Intervention Type DEVICE

The patients who have failed more than 2 eradication courses with standardized treatment were the refractory infection of H. pylori group,and patients who succeeded at the first standardized treatment were the successful treatment group

The result of 13C-urea breath test after treatment

Intervention Type DEVICE

The intervention focused on the results from the result of 13C-urea breath test after treatment.The two groups were treatment based on the antibiotic susceptibility testing. Eight weeks after treatment,a 13C-urea breath test was performed on patients.The successful treatment group were patients with negative in 13C-urea breath tests in the first treatment. The refractory infection of H. pylori group were treatment failure patients after the second standardized treatment.
