Brief summary
The purpose of this study is to evaluate efficacy of a 14-day concomitant therapy for the third-line treatment of Helicobacter pylori infection, and whether it is safe while maintaining an ideal eradication rates.
Detailed description
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. .

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Eradication rate | 6 month | Six weeks after completion of treatment,number of patients get H.pylori eradicated will be investigated.Then eradication rate will be calculated by using intention-to-treat analysis and per-protocol analysis |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The rates of adverse events | 6 month | At the follow-up,adverse events complained by patients will be recorded by an inde pendent researcher, meanwhile a 8point visual analog scale (VAS) was used to evaluate severity of adverse events. |
| Compliance | 6 month | Compliance was evaluated by assessing the total pills patients have taken.Compliance was defined as good when more than 80% or less than 120% of the total pills were taken. |
