About this study
Official title: Efficacy and Safety of 14-day Concomitant Therapy for Refractory Helicobacter Pylori Infection：A Pilot Study
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.
Read the 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. .

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
three kinds of antibioticsDrug
Also called antibiotics
All patients were educated carefully about the medical instructions, including the duration of treatment, possible side effect, the necessity of completing the full 14-day course.
| Study group | Role | What they receive |
|---|---|---|
| 14d concomitant therapy | Experimental | The eligible patients received 14-day concomitant therapy, including vonoprazan and three kinds of antibiotics according to the previous eradication regimens and antibiotic use. Antibiotics are selected from Amoxicillin, Tetracycline, Furazolidone, Levofloxacin, Clarithromycin, Tinidazole, Metronidazole. Receives: Drug: three kinds of antibiotics |
What is being measured
The primary outcome is the main question the study is designed to answer.
Eradication rate
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
Measured: 6 month
Secondary outcomes (2)
The rates of adverse events
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.
Measured: 6 month
Compliance
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.
Measured: 6 month
