Effects of the Multispecies Probiotic Ecologic Barrier in IBS Patients With Upper GI Symptoms and Anxiety, Depression, or Stress
15. juni 2026 oppdatert av: Institute of Gastroenterology and Hepatology, Vietnam
The Effects of the Multispecies Probiotic Mixture Ecologic Barrier for Patients With Irritable Bowel Syndrome With Upper Gastrointestinal Symptoms and Having Anxiety, Depression, and Stress Symptoms
The aim of this clinical trial is to find out whether Ecologic Barrier is effective in supporting the treatment of irritable bowel syndrome (IBS) in adults. The main questions that this trial aims to answer are:
- Does Ecologic Barrier help improve IBS severity when added to standard IBS treatment?
- Does Ecologic Barrier help improve symptoms of anxiety, depression, and stress in patients with IBS?
- Does Ecologic Barrier help improve upper gastrointestinal symptoms when added to standard IBS treatment?
- What adverse events may occur when using Ecologic Barrier? The researchers will compare a group receiving standard symptom-based treatment with another group receiving standard treatment plus Ecologic Barrier.
Participants will:
- Receive IBS treatment for 2 months, with Ecologic Barrier added during either the first month or the second month, depending on random assignment.
- Attend a follow-up visit after 1 month of treatment.
- Take part in interviews about IBS severity, symptom improvement, adverse events, and symptoms of depression and anxiety at baseline, 2 weeks, 4 weeks, 8 weeks, and 12 weeks.

Tidsramme |
|---|---|---|
|
Change from baseline in Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) score at multiple time points
Tidsramme: Baseline (0 weeks), 2 weeks, 4 weeks, 8 weeks, and 12 weeks
|
The IBS-SSS score assesses the severity of IBS symptoms based on abdominal pain intensity, abdominal pain frequency, abdominal distension, dissatisfaction with bowel habits, and interference with daily life
|
Baseline (0 weeks), 2 weeks, 4 weeks, 8 weeks, and 12 weeks
|
|
Irritable Bowel Syndrome-Global Assessment of Improvement (IBS-GAI) score
Tidsramme: 2 weeks, 4 weeks, 8 weeks, and 12 weeks
|
The IBS-GAI is a self-administered questionnaire used to assess the overall change in IBS symptoms compared to the baseline.
Patients answer a question such as "Compared to the way you felt before beginning the trial, have your IBS symptoms changed?" on a 7-point Likert scale ranging from 1 (substantially worse) to 7 (substantially improved).
Higher scores indicate greater improvement
|
2 weeks, 4 weeks, 8 weeks, and 12 weeks
|
|
Percentage of patients achieving Irritable Bowel Syndrome-Adequate Relief (IBS-AR)
Tidsramme: 2 weeks, 4 weeks, 8 weeks, and 12 weeks
|
The IBS-AR is a single, dichotomous question asked to assess if patients obtained adequate relief of their IBS symptoms.
Responses are categorical (Yes or No).
The outcome is reported as the percentage of participants responding "Yes" at each evaluated time point.

Change from baseline in Depression Anxiety Stress Scales-21 (DASS-21) subscale scores
Tidsramme: Baseline (0 weeks), 4 weeks and 8 weeks
|
The DASS-21 is a 21-item self-report questionnaire designed to measure three related negative emotional states: depression, anxiety, and stress (7 items per subscale).
Each item is scored from 0 (did not apply to me at all) to 3 (applied to me very much).
For each subscale (Depression, Anxiety, and Stress), the scores of its 7 items are summed and multiplied by 2. Each individual subscale yields a final score range of 0 to 42.
Higher scores in each subscale indicate greater severity of the respective symptoms.

Baseline (0 weeks), 4 weeks and 8 weeks
|
|
Change from baseline in gastrointestinal symptom severity score
Tidsramme: Baseline (0 weeks), 4 weeks, and 8 weeks
|
Gastrointestinal symptom severity is assessed using a 10-point Visual Analog Scale (VAS).
The scale ranges from 0 to 10, where a score of 0 represents "normal" (no symptoms), 1-3 represents "mild", 4-6 represents "moderate", and 7-10 represents "severe" symptoms.
The final outcome is reported as the change in the total severity score from baseline to each subsequent follow-up period.
Higher scores indicate greater severity of gastrointestinal symptoms

Incidence rate of specific treatment-emergent adverse events (TEAEs)
Tidsramme: 2 weeks, 4 weeks, 8 weeks and 12 weeks
|
The incidence rate of specific treatment-emergent adverse events (TEAEs) is actively assessed at each follow-up.
The pre-specified checklist of symptoms includes: abdominal bloating, abdominal distension, bowel habit disorders, headache, dizziness, nausea, heartburn/retrosternal burning, sleep disorders, and other unlisted events.
For each reported symptom, the onset time and duration will be documented
