Study summary

Probiotics have been proposed as useful therapeutic alternatives for the treatment of irritable bowel syndrome patients. Bacillus clausii is a probiotic that has been used for the treatment of acute diarrhea among adults and pediatric patients, as well as an adjunctive therapy for the treatment for Helicobacter pylori infection. It has been proposed that Bacillus clausii is effective for the treatment of irritable bowel syndrome-related symptoms (especially diarrhea and bloating) in non-controlled trials. The aim of the proposed investigation is to determine whether the administration of Bacillus clausii during two weeks plus dietary advice compared to antispasmodics plus dietary advice would be an effective and safe alternative.

What researchers measure

Primary outcomes

  1. Symptomatic response

    Decrease of at least 50% of symptom severity score - The Irritable Bowel Syndrome Symptom Severity Scale, which consists of five visual analogue scale- questions: their values range from 0 to 100, thus the total score ranges from 0 to 500. Based on previously published studies, clinical response will be defined as a decrease in at least 50% of the initial score

    Time frame: After two weeks of treatment

Secondary outcomes

  1. Symptomatic relapse

    An increase of at least 30% in the symptomatic score based on daily follow up. The score that will be used is the The Irritable Bowel Syndrome Symptom Severity Scale, which consists of five visual analogue scale- questions: their values range from 0 to 100, thus the total score ranges from 0 to 500.

    Time frame: Four weeks after treatment completion
