A Multi-center Study for Individual Treatment of Helicobacter Pylori Infection

Summary

Since the discovery of Helicobacter pylori (H. pylori), many studies have been carried out with the goal of improving H. pylori eradication and therapies have changed from single-antibiotic treatments to the current multi-antibiotic treatments. However, the eradication rate of H. pylori is still less than 80%. The reasons for this low eradication rate are likely to be multi-factorial, including the reduced activity of antimicrobial drugs, poor patient compliance or micro-environment in stomach. In this study, to obtain the higher eradication of H. pylori and discover the different mechanism between the current infection and refractory infection of H. pylori, it is necessary to perform a prevalence survey for eradication of H. pylori based on the results from isolation of H. pylori strains, antibiotic susceptibility testing, CYP2C19 gene polymorphism, drug resistance gene sequencing and 16SrRNA sequencing.
