- Brief Summary
Irritable bowel syndrome (IBS) is a highly prevalent functional pathology which currently has no real standardized and effective therapy, despite having a significant impact on quality of life and on social-health costs.
Post-biotics have demonstrated in various in vitro and in vivo studies the ability to modulate the microbiota, the intestinal barrier function, the immune response as well as having systemic effects, with prospects for good efficacy in treatment of IBS.
- Detailed Description
PostbiotiX Slowing is a food supplement based on Fermented FOS from Lactobacillus paracasei CNCM I-5220, mallow and chamomile.
The Fermented FOS from Lactobacillus paracasei CNCM I-5220 (postbiotic) is the result of a controlled fermentation. The fermentation process allows to eliminate all the individual variability that depends on the microbiota, the diet and the psycho-physical conditions of the single individual, offering a mixture of bacterial metabolites and fermented fiber (postbiotic), which has the functional activity. In addition, as FOS is already fermented it does not induce the formation of gas typical of fiber fermentation in IBS patients, thus providing all the beneficial effects of the fiber without its side effects.
The fermented FOS from Lactobacillus paracasei CNCM I-5220 (postbiotic) is easily absorbed by the gut.
Dosage and method of use: PostbiotiX Slowing 4 g sachets, administered at the dosage of one sachet a day. To pour the contents of the sachet in a glass, add 150 ml of water, mix until complete dissolution of the powder and taken immediately, preferably as soon as awakened, and away from meals.

Group Intervention Description Placebo (Tratment B) Sequence BA PostbiotiX Slowing 4 g sachets PostbiotiX Slowing is a food supplement based on Fermented FOS from Lactobacillus paracasei CNCM I-5220. Each patient will be supplied with the investigational product at Visit 0 (V0, Kit V0, Placebo) and at visit 3 (V3, Kit V3, PostibiotiX Slowing), based on the outcome of the randomization at V0 (Sequence BA, Placebo/PostbiotiX Slowing). PostbiotiX Slowing (Treatment A) Sequence AB PostbiotiX Slowing 4 g sachets PostbiotiX Slowing is a food supplement based on Fermented FOS from Lactobacillus paracasei CNCM I-5220. Each patient will be supplied with the investigational product at Visit 0 (V0, Kit V0, PostibiotiX Slowing) and at visit 3 (V3, Kit V3, Placebo), based on the outcome of the randomization at V0 (Sequence AB, PostbiotiX Slowing/Placebo).
- Primary Outcome Measures
Name Time Method Reduction in symptom intensity 10 weeks Evaluated using a symptom measurement scale, at each visit, on a 4-point Likert scale (IBS symptom scale; 4 symptoms for a minimum sum score of 0, maximum 12).
- Secondary Outcome Measures
Name Time Method Change from baseline after treatment in QqL: up to 10 days Quality of life as assessed by IBS-QoL:
The individual responses to the 34 items are summed and averaged for a total score and then transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS specific quality of lifeFecal metagenomics: up to 10 days Additional functional parameters in stool analysis differences before and after treatment (for example: digestive residues, bile acids, proteic composition)
Change from baseline in IBS-SSS (symptom severity score) up to 4 weeks IBS-SSS is a five-item questionnaire measuring frequency and intensity of abdominal pain, the severity of abdominal distension, dissatisfaction with bowel habits, and the interference of IBS with daily life, scoring from 0 to 500.
Change from baseline after treatment in NRS: up to 10 days Severity score of each of the individual symptoms included in the IBS-SSS (VAS sub-scores), assessed by numeric rating scale (NRS) from 0 to 100
Change from baseline after treatment in HADS: up to 10 days Hospital anxiety and depression scale (HADS):
HADS is a fourteen-item scale with seven items each for anxiety and depression subscales. Scoring for each item ranges from zero to three. A subscale score \>8 denotes anxiety or depression.Analyses of metabolomic: up to 10 days Differences before and after treatment in the Sieric/plasma molecules such as for example Zonulin, soluble CD14, plasmatic inflammatory cytokines, bacterial DNA in the blood, and PBMCs analysis
Adequate overall symptom relief after treatment, up to 10 days To assess adequate overall relief, patients will be asked weekly to answer the question "Compared to how you usually felt before taking the treatment, how would you rate your symptom relief (abdominal pain, bowel habits, and other symptoms of IBS) in the past 10 days?" Possible answers: 1, very relieved; 2, relieved; 3, somewhat relieved; 4, unchanged; 5, slightly worsened; 6, worsened; 7, much worsened.
