NCT02204891

Brief Summary

The aim of the present study is to demonstrate the effect of a mixture of four species of probiotics (Saccharomyces boulardii, Bifidobacterium lactis BB-12, Lactobacillus acidophilus LA-5 and Lactobacillus plantarum) in patients with symptomatic irritable bowel syndrome (IBS) who have culture verified syndrome of intestinal bacterial overgrowth (SIBO) and those who do not have. This will provide direct evidence for the role of probiotics in treating part of the pathogenesis of IBS.

Outcome Measures

Primary Outcomes (1)

  • • The efficacy of probiotics in improvement of symptoms of IBS in patients with SIBO compared to their efficacy in patients with IBS without SIBO.

    This will be assessed after 30 days from start of therapy (visit 2) by comparisons of grading of symptoms and results of OLT between the two groups of treatment.

    30 days

Secondary Outcomes (3)

  • • The efficacy of probiotics in symptoms of IBS in patients with SIBO compared to their efficacy in patients with IBS without SIBO.

    60 days

  • The efficacy of probiotics in specific symptoms of IBS both visits 2 and 3.

    Days 30 and 60

  • • The importance of the inflammation cascade in the pathogenesis of SIBO-related IBS.

    30 days
