ARTICLE HIGHLIGHTS
Research background

Helicobacter pylori (H. pylori) bacteria can cause peptic ulcers and finally result in stomach cancer in certain conditions. Meanwhile, the question of increasing antibiotic resistance must be considered. Given this issue, we need to find ways to reduce drug resistance. This study examined all first-line regimens and compared them with standard triple treatment through a network meta-analysis of randomized controlled trials (RCTs).

Research motivation

To the best of our knowledge, there are no relevant network meta-analyses comparing first-line treatment regimens for eradication of antibiotic-resistant H. pylori strains.

Research objectives

To compare first-line treatment regimens for eradication of antibiotic-resistant H. pylori strains.

Research methods

A comprehensive search was performed in databases such as PubMed, EMBASE, Web of Science, OVID, Cochrane Library (all years up to March 2022), and Cochrane Central Register of Controlled Trials (all years up to March 2022).

Research results

Twenty-five RCTs consisting of 12029 participants [including 1602 infected with clarithromycin (CAM)-resistant strains and 1716 infected with metronidazole (MNZ)-resistant strains] were included, in which seven regimens were used for H. pylori eradication. The results showed that dual therapy containing a high-dose proton pump inhibitor (HDDT) [odds ratio (OR): 4.20, 95% confidence interval (CI): 2.29-8.13] was superior to other therapies for all patients, including those infected with CAM/MNZ-resistant H. pylori strains. In the comparative effectiveness ranking, for CAM-resistant H. pylori strains, HDDT (OR: 96.80, 95%CI: 22.46-521.9) had the best results, whereas standard triple therapy ranked last (SUCRA: 98.7% vs 0.3%). In the subgroup of high cure rates (≥ 90%), HDDT was also generally better than other therapies.

Research conclusions

For eradication of CAM- and MNZ-resistant H. pylori strains, HDDT have a considerable advantage. Overall, HDDT may be a reference for RCTs and other studies of H. pylori eradication.

Research perspectives

Additional multicenter studies are required to confirm the conclusion of this study.
