Abstract:
The efficacy of standard triple therapy for Helicobacter pylori (Hp) eradication has been significantly decreased, or even less than 80%.Abroad studies have shown that Hp eradication rate of sequential therapy is significantly higher than that of triple therapy.At home, we lack a large sample of data analysis to clarify the efficacy of sequential therapy.Aims: To systematically review the efficacy of sequential therapy and triple therapy in Hp eradication at home and abroad.Methods: PubMed, Medline, Embase, Cochrane Library, CNKI, Wanfang, VIP and CBMdisc were retrieved to collect the randomized controlled trials (RCT) comparing sequential therapy and triple therapy in the treatment of Hp infection in last 7 years.Article selection, data extraction and quality evaluation were conducted independently by two reviewers.Meta-analysis was conducted by RevMan 5.3 software.Results: A total of 31 RCT involving 8 371 subjects were included.Meta-analysis showed that Hp eradication rate of sequential therapy was significantly higher than that of triple therapy (83.3% vs.74.7%;RR=1.13, 95% CI: 1.09-1.16).Sixteen domestic studies showed that Hp eradication rate of sequential therapy was significantly higher than that of triple therapy (88.1% vs.78.0%;RR=1.13, 95% CI: 1.10-1.16), fifteen abroad studies showed that Hp eradication rate of sequential therapy was significantly higher than that of triple therapy (79.0% vs.71.8%;RR=1.13, 95% CI: 1.06-1.20).No significant difference in incidence of adverse reactions was found between sequential therapy and triple therapy (20.7% vs.22.0%;RR=0.94, 95% CI: 0.86-1.03).Conclusions: Sequential therapy achieves higher Hp eradication rate than standard triple therapy, and no significant difference in incidence of adverse reactions is found between sequential therapy and triple therapy.Hp eradication rate of sequential therapy is significantly higher than that of triple therapy and is higher than 80% in China, which can be recommended as a Hp eradication supplement of bismuth quadruple therapy.
