Tetracycline and metronidazole based quadruple regimen as first line treatment for penicillin allergic patients with Helicobacter pylori infection
Abstract
Objective: To evaluate the efficacy and safety of tetracycline and metronidazole based quadruple regimen as first line treatment for penicillin allergic patients with Helicobacter pylori (H.pylori) infection. Methods: The clinical data of 120 patients who had infected with H. pylori and were allergic to penicillin in out-patient clinic of Peking University First Hospital was retrospectively collected from January 2014 to June 2016. The regimen included: lansoprazole 30 mg twice a day+ Bismuth 150 mg three times a day+ tetracycline 500 mg three times a day+ metronidazole 400 mg three times a day, for 14 days. All patients were followed up 7 days, 14 days, at least 4 weeks after the treatment. Symptoms and side effects were recorded. The H.pylori status was evaluated by (13)C urease breath test at least 4 weeks after the end of the treatment. Results: All patients included 86 female and 34 male, and the average age is 59 years. There are 104 of the 120 cases who got success in eradication treatment. Mild to moderate adverse effects occurred in 56 cases (46.7%). 10 female patients dropped out because of headache, rash, vomiting and fatigue. The eradication rates were 86.7% (104/120, ITT) and 94.5% (104/110, PP). Conclusions: Tetracycline and metronidazole based 14-day quadruple regimen is effective as first line treatment for penicillin allergic patients with H. pylori infection because of its relatively high eradication rate. Patients should be watched closely during the…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 120 participants or records.
