About this study
Official title: Clinical and Cytokine Response to Saccharomyces Boulardii Therapy in Diarrhea Dominant Irritable Bowel Syndrome
Various studies have been conducted in past using different strains of probiotics in evaluating IBS symptoms. The results are by no means consistent and the overall impact of probiotics in IBS remains unclear. However, recently O'Mahony L et al have shown that Bifidobacterium infantis 35624 alleviates symptoms in IBS; this symptomatic response was associated with normalization of the ratio of an anti-inflammatory to a proinflammatory cytokine (IL-10/IL-12 ratio), suggesting an immune-modulating role for this organism, in this disorder.Saccharomyces boulardii is a probiotic yeast that has been successfully used for the antibiotic induced diarrhea, prevent relapse of Clostridium difficile and Crohn's disease. It ameliorates intestinal injury and inflammation caused by a wide variety of enteric pathogens.We therefore plan a Double-blind, randomized, placebo-controlled study to assess the effects of Saccharomyces boulardii in improving symptomatology of diarrhea predominant IBS and its effect on quality of life. We also plan to assess the changes in the relative production of anti-inflammatory interleukin (IL)-10 to proinflammatory cytokines (IL-12, IL-8 and TNFα).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Saccharomyces boulardii in people with Diarrhea Dominant Irritable Bowel Syndrome, run by Aga Khan University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Assess the efficacy of Saccharomyces boulardii in reducing clinical symptoms, improving cytokines levels and histology features (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2012; AzTrials last refreshed its copy on 7 Nov 2026.
