Clinical Trial Summary

The purpose of this study is to assess and compare the effectiveness of levofloxacin-tetracycline -containing and tinidazole-tetracycline-containing quadruple regimens for the primary treatment of Helicobacter pylori infection in patients allergic to penicillin.


Clinical Trial Description

Helicobacter pylori(H.pylori), which infects about 50% of the global population, has been recognized as a main risk factor of multiple gastric pathologies, especially non-cardiac gastric cancer. Strongly evidence supports that H.pylori eradication is an effective approach to reduce the incidence of those pathologies.However,Helicobacter pylori eradication is a challenge in patients allergic to penicillin. Therefore, the investigators aim to assess and compare the effectiveness of levofloxacin-tetracycline -containing and tinidazole-tetracycline-containing quadruple regimens for the primary treatment of Helicobacter pylori infection in patients allergic to penicillin. ;
