Efficacy and Safety of 14-day Concomitant Therapy for Helicobacter Pylori Infection
- Conditions
- Helicobacter Pylori Infection
- Interventions
- Drug: esomeprazole, amoxicillin, furazolidone，tetracycline
- Registration Number
- NCT03726099
- Lead Sponsor
- Shandong University
- 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 two or more treatment failure, and then evaluates whether adverse effects are tolerable. .

Group Intervention Description 14d concomitant therapy esomeprazole, amoxicillin, furazolidone，tetracycline Patients will receive a 14-day concomitant therapy containing esomeprazole, amoxicillin, tetracycline and furazolidone.
- Primary Outcome Measures
Name Time Method Eradication rates 6 months Both intention to treat(ITT) and per-protocol(PP) analyses will be used for the assessment of the eradication rates of Helicobacter pylori infection. The ITT analysis includes all the patients who take at least one dose of the study medications. The PP analysis is limited to patients who take over 90% of the study medications and complete follow-up.
- Secondary Outcome Measures
Name Time Method The rate of good compliance 6 months Patients taken over 90% of drugs are considered to have a good compliance.
The rate of adverse events happening 6 months Common adverse events will be measured using a 8-point Likert scale, and patients rate their symptoms from 0 (none) to 8 (severe) during the treatment process.
Changes of dyspepsia symptoms after Helicobacter pylori eradication 6 months A list of dyspepsia symptoms will be recorded. Difference of dyspepsia symptoms before and after the therapy will be compared.
