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):

Fecal Microbiome Taxonomic Profile and Predicted Functional Potential of the Microbiome (It will use the bioinformatic program PICRUSt as follows: a. Inflammation Index, b. Alpha Diversity, c. Beta Diversity, d. Compositional Analysis, e. LEfSe (Linear discriminant analysis Effect Size), i. Taxonomic, ii. Functional). Measurement time: At baseline (day 0), 1 month and, 3 months

Key secondary outcomes:

1- Quality of life (SF-36 International Health Survey, which evaluates various aspects of the quality of life related to an individual's mental health). Measurement time: At baseline (Day 0), 1 month and 3 months 2- Adverse Events- AE (Presence of the AE (It doesn't seem to have any AE, Possible AE, Similar to AE, AE); Intensity of the AE (It doesn't seem to have any AE, Mild (Does not produce restrictions in daily activities), Moderate (Produces partial restriction of daily activities), Severe (inability to perform daily activities))). Measurement time: 3 months 3- Hematological variables and clinical chemistry (Laboratory values will be determined using the Cobas 6000 automatic immunochemical analyzer from the Roche Diagnóstica company. It will be determined Liver enzymes, Creatinine and Urea; Hematological parameters (Blood glucose, Leukocytes, Erythrocytes, Hemoglobin, Hematocrit, MCV, MCHC, RDW, Platelets, MPV, Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils)). Measurement time: At baseline (Day 0), 1 month and 3 months 4- Inflammatory variables (C-reactive protein (normal values less than 10 mg/L), Calprotectin in feces (Values in ug/g. Normal values less than 50ug/g. A value between 50-200ug/g indicates mild intestinal inflammation)). Measurement time: At baseline (Day 0), 1 month and 3 months 5- Intestinal Transit
