Background and purpose: 

The role of probiotics in the treatment of gastrointestinal infections is increasingly being documented as an alternative or complement to antibiotics, with the potential to decrease the use of antibiotics or reduce their side effects. Although antibiotics-based Helicobacter pylori eradication treatment is 90% effective, it is expensive and causes antibiotic resistance associated with other adverse effects. Probiotics have an in vitro inhibitory effect on H. pylori. Animal studies demonstrated that probiotic treatment is effective in reducing H. pylori-associated gastric inflammation. About 12 human studies investigated the efficacy of combinations of antibiotics and probiotics, whereas 16 studies used probiotic alone as an alternative to antibiotics for the treatment of H. pylori infection. Most of the studies showed an improvement of H. pylori gastritis and decrease in H. pylori colonization after administration of probiotics. However, no study could demonstrate complete eradication of H. pylori infection by probiotic treatment. Probiotic combinations can reduce adverse effects induced by H. pylori eradication treatment and, thus, have beneficial effects in H. pylori-infected individuals. Long-term intakes of products containing probiotic strains may have a favorable effect on H. pylori infection in humans, particularly by reducing the risk of developing disorders associated with high degrees of gastric inflammation.
