Helicobacter Pylori First-line Treatment Containing Tetracycline in Patients Allergic to Penicillin

Shandong University106 enrolled

Overview

The purpose of this study is to assess and compare the effectiveness of levofloxacin-tetracycline -containing and metronidazole-tetracycline-containing quadruple regimens for the primary treatment of Helicobacter pylori infection in patients allergic to penicillin.

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 metronidazole-tetracycline-containing quadruple regimens for the primary treatment of Helicobacter pylori infection in patients allergic to penicillin.

Outcomes

Primary Outcomes

Eradication rates in 2 groups

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.

Time frame: 12 months

Secondary Outcomes

The rate of improving dyspepsia symptoms after Helicobacter pylori eradication

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.

Time frame: 12 months

The rate of adverse events happening

Similarly, adverse events will also be measured by the Likert scale.

Time frame: 12 months
