Objective  To review the eradication rate for Helicobacter Pylori (H. pylori) eradication therapy with Ranitidine bismuth citrate (RBC).
Methods  A systematic review of all the relevant randomized controlled trials (RCTs) was performed according to International Cochrane Collaboration. Data Source RCTs were identified from specialized trials register of Cochrane U GDP Group, the Cochrane library, additional electronic search (including MEDLINE and CBM), handsearching, and personal contact with pharmaceutical companies.
Data Selection  Randomized clinical trials comparing RBC or RBC in combination with other antibiotics such as proton pump inhibitor, H2-receptor antagonist, other bismuth or placebo were included. No language and blinding limitations were applied.
Inclusion criteria  Data were extracted independently by two reviewers. The methodological quality of trials was assessed by the Jadad-scale plus allocation concealment. Statistics analysis was managed by using RevMan 4. 1.
Results  Fifteen randomized clinical trials including 3 638 patients were included, with eight trials of high methodological quality. Meta-analysis indicated that odds ratio was 3.06 (95%CI 2.62 to 3. 58, P  lt; 0. 000 01) comparing RBC to controls. But the heterogeneity was significant (P  lt; 0. 000 01), so we choose random effects model. Then the odds ratio was 2.05 (95%CI 1. 29 to 3. 25, P=0.002). No serious adverse effects were found. Sensitivity analysis showed that the specimens and the quality of RCT haven’t affected researching result.
Conclusion  RBC is more effective in Helicobacter Pylori eradication therapy than others.
