Hybrid, sequential and concomitant therapies for Helicobacter pylori eradication: A systematic review and meta-analysis.

AIM: To compare hybrid therapy (HT) with traditional sequential therapy (ST) and concomitant therapy (CT) for Helicobacter pylori (H. pylori) eradication. METHODS: We performed an electronic search of PubMed, Embase, and the CENTRAL database. Randomized controlled trials (RCTs) of HT were included in the meta-analysis. The primary outcome was the eradication rate of H. pylori. The secondary outcomes included the compliance rate and adverse event rate. Effect estimates were pooled using the random-effects model. RESULTS: Twelve studies were included. Pooled results showed no significant differences in eradication rate between HT and ST in per-protocol (PP) analysis (RR = 1.03, 95%CI: 0.94-1.12, P = 0.59) or in intention-to-treat (ITT) analysis (RR = 1.00, 95%CI: 0.89-1.12, P = 0.94). HT and ST showed similarly high compliance rate (96% vs 98%, P = 0.55) and acceptable adverse event rate (30.3% vs 28.2%, P = 0.63). No significant results were seen in the eradication rate between HT and CT in PP analysis (RR = 1.01, 95%CI: 0.96-1.05, P = 0.76) or in ITT analysis (RR = 0.99, 95%CI: 0.95-1.03, P = 0.47). HT displayed a slightly higher compliance rate than CT (95.8% vs 93.2%, P < 0.05). The adverse event rates of HT and CT were similar (39.5% vs 44.2%, P = 0.24). CONCLUSION: Compared with ST or CT, HT yields a similar eradication rate, high compliance rate, and acceptable safety profiles.
