Detailed Description
Helicobacter pylori(H.pylori), which infects about 50% of the global population, has been recognized as a main risk factor of multiple gastric pathologies, especially non-cardiac gastric cancer. Strongly evidence supports that H.pylori eradication is an effective approach to reduce the incidence of those pathologies.However,Helicobacter pylori eradication is a challenge in patients allergic to penicillin.
Therefore, the investigators aim to assess and compare the effectiveness of levofloxacin-tetracycline -containing and tinidazole-tetracycline-containing quadruple regimens for the primary treatment of Helicobacter pylori infection in patients allergic to penicillin.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Eradication rates in 2 groups
Time Frame: 24 months
|
Both intention to treat(ITT) and per-protocol(PP) analyses will be used for the assessment of the eradication rates of Helicobacter pylori infections in two groups.
The ITT analysis includes all randomly assigned 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.

24 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The rate of improving dyspepsia symptoms after Helicobacter pylori eradication
Time Frame: 24 months
|
Dyspepsia symptoms will be measured using a 8-point Likert scale, and patients rate their symptoms from 0 (none) to 8 (severe) before and after the Helicobacter pylori eradication.
|
24 months
|
The rate of adverse events happening
Time Frame: 24 months
|
Similarly, adverse events will also be measured by the Likert scale.
|
24 months
|
The rate of good compliance
Time Frame: 24 months
|
Patients taken over 90% of drugs are considered to have a good compliance.
