About this study
Official title: Helicobacter Pylori Rescue Treatment Containing Tetracycline in Patients Allergic to Penicillin:a Prospective Randomized Controlled Study
The purpose of this study is to assess and compare the effectiveness of furazolidone-tetracycline-containing and metronidazole-tetracycline-containing quadruple regimens for the rescue treatment of Helicobacter pylori infection inpatients allergic to penicillin.
Read the detailed 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 furazolidone-tetracycline-containing and metronidazole-tetracycline-containing quadruple regimens for the rescue treatment of Helicobacter pylori infection in patients allergic to penicillin.
- Conditions
- Helicobacter Pylori Infection
