Abstract
Helicobacter pylori (H. pylori) infection is associated with the development of multiple diseases. The eradication rate of H. pylori has gradually decreased, suggesting the need to discover more effective therapies. This study aimed to compare the effectiveness of first-line treatments including high-dose dual therapy (HDDT), bismuth-based quadruple therapy (BQT), sequential therapy (ST), concomitant therapy (CT) and hybrid therapy (HT) by network meta-analysis (NMA). A comprehensive search on PubMed, Embase, Cochrane Library and Web of Science, was performed from their inception to 1 September 2019. A network analysis of randomized controlled trials (RCTs) comparing first-line therapies were carried out using Stata 14.0 and Revman 5.2. Moreover, a sensitivity analysis was conducted by omitting non-Asian studies. Finally, 41 RCTs with 14 119 patients were included. The NMA showed that, in terms of eradication rate, ST for 10 days (ST-10) was significantly lower than CT for 10 or 14 days (CT ≥ 10). Sensitivity analysis among the Asian population showed that ST-10 denoted the lowest effectiveness among the interventions. The ranking results based on probability showed that HDDT ranked first for the eradication rate. As for adverse events, HDDT was significantly less than BQT and CT regardless of duration, while BQT for 14 days represented higher adverse events than ST, HT and CT ≥ 10. HDDT ranked first among the therapies. In conclusion, HDDT for 14 days appeared to be the most optimal first-line therapy for H. pylori among the Asian population with comparable efficacy and compliance but causing fewer adverse events.
