Background: Bismuth quadruple (BQT) and non-bismuth quadruple (N-BQT) therapies are the recommended first-line treatments for Helicobacter (H.) pylori infection. Objective: To compare the efficacy of BQT and N-BQT in clinical practice in an area with high clarithromycin resistance, choosing the regimen on the basis of previous exposure to clarithromycin. Methods: A total of 404 consecutive H pylori-positive, naïve patients were enrolled. A total of 203 patients without previous exposure to clarithromycin received N-BQT, 100 patients for 10 days and 103 for 14 days, whereas 201 with previous exposure to clarithromycin received 10-day BQT. Efficacy and treatment-related adverse events were assessed. Results and Conclusions: Eradication rates by intention-to-treat analysis were 88.2% for N-BQT and 91.5% for BQT (P =.26); per-protocol analysis eradication rates were 91.2% and 95.8% for N-BQT and BQT, respectively (P =.07). Eradication rates were significantly higher with 14-day than 10-day CT (P <.003). Almost all patients had a good compliance with both N-BQT (95.6%) and BQT (95%). Adverse events occurred in 24.1% and 26.9% (P =.53) of patients in the N-BQT and BQT group, respectively. In conclusion, clarithromycin-containing non-bismuth or bismuth quadruple therapy, based on the knowledge of previous clarithromycin exposure, is effective and safe even in an area of high prevalence of clarithromycin-resistant H pylori strains.

Abstract

Background: Bismuth quadruple (BQT) and non-bismuth quadruple (N-BQT) therapies are the recommended first-line treatments for Helicobacter (H.) pylori infection. Objective: To compare the efficacy of BQT and N-BQT in clinical practice in an area with high clarithromycin resistance, choosing the regimen on the basis of previous exposure to clarithromycin. Methods: A total of 404 consecutive H pylori-positive, naïve patients were enrolled. A total of 203 patients without previous exposure to clarithromycin received N-BQT, 100 patients for 10 days and 103 for 14 days, whereas 201 with previous exposure to clarithromycin received 10-day BQT. Efficacy and treatment-related adverse events were assessed. Results and Conclusions: Eradication rates by intention-to-treat analysis were 88.2% for N-BQT and 91.5% for BQT (P =.26); per-protocol analysis eradication rates were 91.2% and 95.8% for N-BQT and BQT, respectively (P =.07). Eradication rates were significantly higher with 14-day than 10-day CT (P <.003). Almost all patients had a good compliance with both N-BQT (95.6%) and BQT (95%). Adverse events occurred in 24.1% and 26.9% (P =.53) of patients in the N-BQT and BQT group, respectively. In conclusion, clarithromycin-containing non-bismuth or bismuth quadruple therapy, based on the knowledge of previous clarithromycin exposure, is effective and safe even in an area of high prevalence of clarithromycin-resistant H pylori strains.
