NCT03404440

Brief Summary

Meta-analyses involving \>4000 subjects with probiotics added to antimicrobial Helicobacter pylori eradication therapy in populations with antibiotic resistance have reported a mean increase in eradication rate of 12.2%. It is unclear how to translate that result into clinical practice. To evaluate whether administration of Lactobacillus reuteri plus a PPI without antibiotics would eradicate H. pylori infections. This was a double-blind placebo-controlled randomized 2 site study of L. reuteri (2 x 108 CFU L. reuteri DSM 17938 plus 2 x 108 CFU L. reuteri ATCC PTA 6475) 7 times per day or matching placebo plus 20 mg pantoprazole b.i.d. for 4 weeks. Cure was defined by negative 13C-UBT, 4 weeks after therapy. Sample size was based on obtaining \>50% cures to be clinically useful as monotherapy.
