Abstract
In the last few years, numerous new potassium-competitive acid blocker (P-CAB)-based randomized controlled trials (RCTs) concerning the first-line regimens for Helicobacter pylori infection treatment from various countries have been published. However, no network meta-analysis (NWM) exists, which examines the comparative efficacy and safety of P-CAB-based dual, triple, and quadruple treatments, and, therefore, in this NWM, we examined this matter comparing efficacy and safety of these P-CAB-based regimens. Databases were searched for identification, screening, eligibility, and inclusion of relevant RCTs. Extracted data were entered into a Bayesian NWM, and the ranking order for each regimen was evaluated by means of the surface under the cumulative ranking area values. Twenty-five eligible RCTs were included with 7,605 patients randomized to 6 first-line regimens, i.e. P-CAB dual therapy, P-CAB triple therapy, P-CAB quadruple therapy, PPI dual therapy, PPI triple therapy, and PPI quadruple therapy. The surface under the cumulative ranking area values (%) for these 6 regimens were 92.7, 62.5, 33.9, 75.1, 19.4, and 16.3, respectively. The comparative effectiveness ranking showed that P-CAB dual therapy regimen ranked first for efficacy and last for adverse effects and had the best profile for integrated efficacy-safety. In this NWM concerning the comparative efficacy and safety of P-CAB-based dual, triple, and quadruple regimens for the first-line H. pylori infection treatment, the overall results showed that P-CAB-based dual treatment ranked first for efficacy with the best-integrated efficacy-safety profile. This is of importance, since the dual regimens overcome the crucial issue of clarithromycin resistance. Consequently, these findings are expected to be useful in helping clinical decision making and future guidelines.
