Brief Summary

Evaluation of the effects of butyrate ( BitirBioma) and palmitoylethanolamide( PEA=PeaBioma) on intestinal permeability and gut microbiota composition in patients with irritable bowel syndrome.

Study B/P 3_1 is an interventional study involving the use of food supplements on the market (BitirBioma Plus and PeaBioma Plus), single-center, double-blind, placebo-controlled, crossover, randomized, in n=50 patients with bowel syndrome irritable, diarrheal and mixed variant (IBS-D and IBS-M), lasting for one year.

The study has two arms: Group 1: n=25 Treatment A e Group 2: n=25 Treatment B (with - Treatment A: 3 capsules/day of butyrate (625 mg) + 3 capsules/day PEA (200 mg) at a ratio of dosage of 3/1 - Treatment B: Placebo (3+3/day capsules of starch).

Eligible subjects with IBS will be randomized in a 1:1 ratio to treatment A or treatment B for six weeks. After the first treatment period, there is a 14-day washout period.

Hence, individuals will be treated with B/A treatment for additional six weeks, according to the crossover design.

In the two treatment periods, subjects will be required to complete a visual analogue score VAS questionnaire to assess gastrointestinal symptoms and Stool Bristol Scales. During the visit, the subjects will have to record Questionnaire Rome IV to evaluate their quality of life. At the same time, it will be theirs required to provide:

• fecal sample for the evaluation of the composition of fecal microbiota (Biomaplan Kit)
• a urine sample for the evaluation of intestinal permeability (Gastropack) a capillary blood sample and a serum sample for the detection of Zonulin (Kit Healthy gut and Immundiagnostik AG )
• a capillary blood sample and a serum sample for the detection of Zonulin (Kit Healthy gut and Immundiagnostik AG )

Detailed Description

Ulcerative colitis (UC) is a chronic inflammatory condition affecting the colon, characterized by relapsing and remitting mucosal inflammation. It presents with symptoms like bloody diarrhea, rectal urgency, fatigue, and abdominal pain. While various therapies are available for managing UC, including medications like amino salicylates, corticosteroids, immunomodulators, and biologics, there's ongoing research into supportive treatments like probiotics.

Probiotics are beneficial microorganisms that can positively influence gut health by modifying the gut microbiota, improving intestinal barrier function, and balancing immune response. Several studies have investigated their efficacy in UC management. Notably, the probiotic mixture VSL#3, containing strains of Lactobacillus and Bifidobacteria, has shown promising results in inducing remission in UC patients.

Other probiotic products like E. coli Nissle 1917, L. rhamnosus GG, and L. casei DG have also demonstrated effectiveness in maintaining disease remission or prolonging relapse-free periods in UC patients. The product Prolife 10 FORTE, containing multiple strains of Lactobacillus, Bifidobacteria, and Bacillus coagulans, along with prebiotic components and vitamins, has shown potential in positively influencing gut microbiota composition and metabolic activity in healthy individuals.

Based on these promising findings, further investigation is warranted to evaluate the potential of Prolife 10 FORTE in improving the gut microbiota composition of UC patients during the remission phase.
