Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
IBS results from an interaction among several factors, including genetic predisposition, gastrointestinal motility, visceral hypersensitivity, immune activation with minimal inflammation, alterations in intestinal microbiota, increased intestinal permeability, and food sensitivity.
IBS is associated with a high economic burden for the health care costs and work absenteeism.
The disease course is represented by unchanged symptoms in 30 to 50 percent or progression of symptoms in 2 to 18 percent. On the other hand, an improvement in symptoms was recorded in 12 to 38 percent of patients.
Of note, the management of patients with IBS is critical. Several therapeutic options have been proposed looking to the underlying pathophysiological mechanisms (i.e., dietary modification, osmotic laxatives, lubiprostone, guanylate cyclase agonists, 5-hydroxytryptamine (serotonin) 4 receptor agonists, antidiarrheal agents, bile acid sequestrants, 5-hydroxytryptamine (serotonin) 3 receptor antagonists, antispasmodic agents, antidepressants, antibiotics, probiotics, behavior modification, anxiolytics, mast cell stabilizer, and fecal transplantation).
Since quantitative and qualitative disturbances of intestinal microbiota can occur in IBS, interesting data support the use of probiotics to modulate intestinal microbiota. The genus Bifidobacterium is one of the most representative member of the intestinal microbiota with large effects on overall gut physiology. Its metabolic activity results from the degradation of oligo-fructose, production of acetate, and promotion of butyrate production by means of cross-feeding. In particular, B. longum has beneficial effects on the immune system, and can be considered a promising candidate for prevention/treatment of immune-mediated inflammatory diseases.
The combination of specific bacterial strains of Lactobacillus with Bifidobacterium species plays an interesting role in reserving the intestinal dysbiosis. The synergic action results in survival on adverse gastrointestinal conditions, adhesion to intestinal mucosa, immunomodulatory activities, and restoration of gut environment.
The present study aimed to investigate the effects of a novel formulation of B. longum BB536 and L. rhamnosus HN001 with vitamin B6 on the gut microbiota and intestinal permeability in IBS subjects.

Study Design
Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.
RANDOMIZED
CROSSOVER
* A run-in period of one month when symptoms, intestinal permeability, intestinal microbiota, and dietary evaluations were performed;
* Phase 1: randomization to treatment or placebo lasting 30 days;
* Wash-out period lasting 15 days, at the end of which symptoms were assessed;
* Phase 2: switch to next treatment in a crossover fashion. Treatment lasted for 30 days and at the end symptoms, intestinal permeability, and intestinal microbiota were evaluated again.
TREATMENT
NONE
Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Probiotic
The study design is a crossover randomized double-blind two-block placebo-controlled single center trial with an allocation ratio of 1:1 conducted between February 2017 and May 2018. Subjects are randomized at baseline visit to receive Block 1 (Zircombi 3 g, containing Bifidobacterium longum BB536 four billion CFU, Lactobacillus rhamnosus HN001 one billion CFU with B6 vitamin 1.4 mg) and Block 2 (placebo: maltodextrins, corn starch, silicon dioxide) depending on the randomization sequence. Subjects received one sachet pack daily containing placebo or probiotic. The active treatment was undistinguishable from placebo by physical and organoleptic characteristics. Participants in the study followed a free diet.
Zircombi
Twenty-five IBS patients (Rome IV criteria) (M:F= 8:17; age 48 yrs ± 11 SD) were enrolled and randomized to treatment or placebo in a a crossover randomized double-blind two-block placebo-controlled trial. Abdominal pain and bloating, intestinal habits, severity of disease, intestinal permeability, and intestinal microbiota were performed at the different time points.
Placebo
Same appearance of probiotic.
Placebo
Given as comparable packets. Same duration.
