Helicobacter Pylori Infection Clinical Trial
Official title:
Efficacy and Safety of a 14-day Modified Sequential Therapy for Refractory Helicobacter Pylori Infection: an Open Randomized Pilot Study
The purpose of this study is to assess efficacy of a new 14-day sequential therapy for the rescue treatment of refractory Helicobacter pylori infection, and whether it is safe while maintaining an ideal eradication rates. The researchers also want to testify whether a double-dose rabeprazole has equal efficacy to double-dose esomeprazole to provide sufficient acid inhibition.
Half of the world's population is infected with Helicobacter pylori. Strong evidence supports that 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 emerging antibiotic resistance of H. pylori worldwide. An ideal rescue therapeutic regimen to cure refractory H.pylori infection is currently warranted. Traditional sequential therapy failed to achieve an ideal eradication rates (over>95%) as a third line treatment in the region with high antibiotic resistance. This study aims to evaluate the efficacy of 14-day modified sequential therapy in the patients with two or more treatment failure, and whether the adverse effects of this new modified sequential therapy are tolerable. Then, this study will also compare the performance of a double-dose esomeprazole with double-dose rabeprazole containing therapy to optimize therapeutic regimen. ;
