Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Inflammatory Bowel Disease

Intervention(s):

Group A - OPTIGUT PRO (Experimental group): Participants will receive a capsule of OPTIGUT PRO every 12 hours by oral route during 6 months. The capsule is a high-precision symbiotic formulation designed using Bioflux techniques, combining the action of four probiotic bacteria (Bacillus clausii AO1025, Bifidobacterium bifidum BB47, L. reuteri LE16, and L. gasseri LG23) and a prebiotic, inulin. Group B – Placebo (Control group): Participants will receive a capsule of placebo every 12 hours by oral route during 6 months.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Calprotectin Levels (It is considered a biomarker of intestinal inflammation. Increased levels correlate well with the progression of Crohn's disease. Fecal calprotectin concentrations below 100 μg/g reliably indicate patients with a low risk of clinical recurrence in endoscopic remission settings, for whom invasive endoscopic procedures can be avoided). Measurement time: At baseline and at 6 months.

Key secondary outcomes:

1. Quality of Life (SF-36 Health Survey in Spanish). Measurement time: At baseline and, 6 months 2. Adverse effect and its intensity (It will be measured by considering the presence of the adverse effect under four categories (No apparent adverse effect, Possible adverse effect, Similar to an adverse effect, Adverse effect) and its intensity classified into three categories (Mild, Moderate, Severe)). Measurement time: During the study, up to 6 months. 3. Muscle mass (The gain of muscle mass will be measured in grams using the TANITA bioimpedance device). Measurement time: At baseline and, at 6 months. 4. Inflammatory biomarker (IL-6 and C-Reactive Protein (CRP) will be measured. IL-6: Serum levels will be measured with normal range levels considered <5pg/ml. CRP: Serum levels will be measured with normal range levels considered between 0 and 5mg/L). Measurement time: At baseline, 3 months and, 6 months. 5. Blood chemistry (Serum levels will be evaluated considering the following normal ranges: GLUCOSE (3.3 - 6.1 mmol/L), CREATININE (47.6 - 113.4 μmol/L), CHOLESTEROL (<5.2 mmol/L), TRIGLYCERIDES (0.46 - 1.8 mmol/L), HDL (0.9 - 3 mmol/L), LDL (0 - 3.4 mmol/L), ALT (TGP)(<45 U/L), AST (TGO) (<40 U/L)). Measurement time: At baseline, 3 months and, 6 months. 6. Bacterial composition of the specific fecal microbiome (It will be determined by sequence studies of the 16S ribosome subunit (16S rRNA V3-V4) in stool samples from a group of randomly selected individuals from both groups. Taxonomic Profile and compositional analysis will be used. The taxonomic profile analysis will be performed using PICRUSt to determine the Inflammation Index, Alpha Diversity and Beta Diversity. The compositional analysis will be performed using the prediction analysis of functional markers (orthologous genes) from the study of the microbiome using LEfSe (Linear discriminant analysis Effect Size)). Measurement time: At baseline and at 6 months.
