ObjectiveTo systematically review the efficacy and safety of probiotics for the treatment of Helicobacter pylori (H.pylori) infection in children. MethodsWe electronically searched The Cochrane Library, PubMed, EMbase, CNKI, VIP and WanFang Data databases to collect randomized controlled trials (RCTs) about probiotics for the treatment of H.pylori infection in children from inception to January 2015. The references of included studies and conference proceedings were manually searched for additional studies. Two reviewers independently screened literature, extracted data and assessed the risk of bias of include studies. Then, meta-analysis was performed by using RevMan 5.3 software. ResultsA total of twelve RCTs were included, involving 1 227 patients. The result of meta-analysis showed that the probiotics adjuvant therapy group was superior to the control group in H.pylori eradication rates (OR=2.23, 95%CI 1.66 to 2.99, P<0.000 01) and the incidence of adverse effect (OR=0.31, 95%CI 0.18 to 0.53, P<0.000 1). ConclusionCurrent evidence shows that probiotics adjuvant therapy may be a new effective and safe solution in the treatment of H.pylori infections in children. Due to the limited quality and quantity of the included studies, more higher quality studies are needed to verify the above conclusion.
