ABSTRACT
OBJECTIVE:
This study aims to evaluate the efficacy and safety of three bismuth-based quadruple regimens for eradication of Helicobacter pylori (H pylori) infection in a large number of H pylori-positive patients with or without previous eradication therapy.METHODS:
Consecutive adult patients with H pylori infection, regardless of previous eradication therapy, were eligible for the present study. Three bismuth-based quadruple regimens were selected according to the past history of antibiotics use (A) esomeprazole, amoxicillin, clarithromycin, and colloidal bismuth tartrate; (B) esomeprazole, amoxicillin, furazolidone, and colloidal bismuth tartrate; and (C) esomeprazole, doxycycline, furazolidone, and colloidal bismuth tartrate. All patients received a 14-day course of treatment, and 13 C/14 C urea breath test was utilized at four weeks after the completion of treatment to determine the H pylori eradication. Then, the eradication rates were calculated in terms of intention-to-treat (ITT) and per-protocol (PP) analyses. Adverse events (AEs) were recorded during the treatment.RESULTS:
Overall, 1,226 patients were recruited, and 331, 57, and 838 patients were allocated to receive regimens A, B, and C, respectively. The H pylori eradication rates were 84.0%, 82.5%, and 82.9% (ITT) and 94.6%, 92.2%, and 93.7% (PP), respectively, in regimens A, B, and C. However, there was no significant difference among these three regimens. The incidence of AEs was 4.6% for all patients during the study, that is, 3.3%, 10.5%, and 4.7% for regimens A, B, and C, respectively. All AEs were mild and recovered at the follow-up visit.CONCLUSION:
All three bismuth-based quadruple regimens based on the previous antibiotic use can achieve satisfactory eradication rates for H pylori infection and are safe.Palavras-chave
