Evaluation of the Effects of Colipral on Microbiota Gut Composition in Patients Presenting With Ulcerative Colitis During Remission Phase and Functional Disorders (COLIPRAL)
Evaluation of the Effects of Colipral® (E.Coli 5C LMG S-33222) on Microbiota Gut Composition in Patients Presenting With Ulcerative Colitis During Remission Phase and Functional Disorders
The study is a double-blind, placebo-controlled, crossover, randomised trial, in which enrolled subjects will be included for 18 months. This study aims to evaluate the effect of the Colipral as a Food Supplement prescribed according to the standard of care of patients suffering UC during remission phase and DGBI.
The primary objective of the study is to evaluate the variation in gut microbiota, specifically focusing on bacterial diversity and abundance, in patients with UC during the remission phase and DGBI.
The secondary objective of the study is to evaluate the clinical parameters variations (based on fecal calprotectin and IBDQ's score before and after the treatment), the severity of gastrointestinal symptoms, the quality of life, and the maintenance of the remission phase in patients with UC in remission and DGBI.

Descrizione dettagliata
The primary endpoint will be the variation in gut microbiota analyzed through 16S rRNA gene sequencing from a fecal sample of patients presenting UC during remission phase and DGBI at three time points: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
The secondary endpoint will be the assessment of the clinical parameters variation based on fecal calprotectin in patients presenting UC during remission phase and DGBI at three time points: T=0 (baseline, before treatment), T=1 (after an additional 60 days of treatment A or B), and T=3 (after 60 days of treatment A or B).
The severity of gastrointestinal symptoms and quality of life will be assessed using the IBDQ, IBS SSS, VAS, and Bristol Stool Scale questionnaires at three time points: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B). Patients' dietary habits will be analysed using the WCRF questionnaire at the first and final visit.

Fecal calprotectin levels
Lasso di tempo: T=0 (baseline, before treatment), T=1 (after an additional 60 days of treatment A or B), and T=3 (after 60 days of treatment A or B)
|
Concentration of fecal calprotectin measured in mg/Kg as an objective marker of intestinal inflammation.
Normal value is <250 mg/Kg, with higher values indicating active intestinal inflammation.
|
T=0 (baseline, before treatment), T=1 (after an additional 60 days of treatment A or B), and T=3 (after 60 days of treatment A or B)

Quality of life in patiets with inflammatory bowel disease
Lasso di tempo: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
|
Quality of life will be assessed using the IBDQ (Inflammatory Bowel Disease Questionnaire).
This is a 32-item questionnaire that evaluates symptoms and well-being over the prior two weeks using a 7-point scale from 1 (worst) to 7 (best).
Total scores range from 32 to 224, with higher scores indicating a better quality of life.
|
T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
|
|
Dietary habits
Lasso di tempo: T=0 (baseline, before treatment) and T=3 (after taking both treatment A and treatment B)
|
Patients' dietary habits will be analysed using the WCRF questionnaire, which assesses dietary habits, particularly the questions focus on common eating patterns.
|
T=0 (baseline, before treatment) and T=3 (after taking both treatment A and treatment B)

|
Gastrointestinal symptom severity in patients with Irritable Bowel Syndrome
Lasso di tempo: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
|
The severity of gastrointestinal symptoms will be assessed using IBS Symptom Severity Scale, which measures the intensity and frequency of abdominal pain, severity of abdominal distention, and dissatisfaction with bowel habits.

|
T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
|
|
Severity of gastrointestinal symptoms
Lasso di tempo: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
|
Severity of gastrointestinal symptoms will be assessed using the Visual Analog Scale (VAS) that measure for acute and chronic pain by making a handwritten mark on a 10-cm line (0 = "No Pain" to 100 = "Worst Imaginable Pain").
The patient marks a point on the line corresponding to their symptom intensity.
|
T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).

|
Severity of gastrointestinal symptoms
Lasso di tempo: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
|
Severity of gastrointestinal symptoms will be assessed using Bristol Stool Scale.
This is a chart that rate the stools into seven categories based on form and consistency.
Types 1,2 (constipation), types 3,4 (normal bowel function), types 5,6,7(diarrhea).
|
T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
