Efficacy and Safety of 14-day Concomitant Therapy for Refractory Helicobacter Pylori Infection：A Pilot Study

Detaljeret beskrivelse
Helicobacter pylori infects half of the world's population. H.pylori eradication is an effective approach to reduce the risk of developing gastric cancer. However, eradication rates of first-line therapy decreased over years due to the rapidly increasing antibiotic resistance of H. pylori worldwide. An ideal rescue therapeutic regimen to cure refractory H.pylori infection is currently warranted.
Few published paper evaluated the efficacy of 14-day furazolidone containing concomitant therapy in the third line treatment. This study aims to propose a new concomitant therapy for the patients with three or more treatment failure, and then evaluates whether adverse effects are tolerable. .
