NO
To assess whether Salacia extract modulate gut microbiota and influence on the abdominal symptom and stool condition compared to placebo in diarrhea predominant irritable bowel syndrome patients.
Efficacy
Confirmatory
Amount of increase of the genus Bifidobacterium proportion from baseline to 4 weeks
Improvement rate of abdominal pain after 4 weeks
Improvement of IBS-Severity Index score
Improvement of IBS-QOL score
Improvement of Bristol stool scale
Composition of gut microbiota (amount of increase of the genus Veillonella proportion from baseline to 4 weeks, amount of increase of the genus Lactobacillus proportion from baseline to 4 weeks)
[Exploratory outcomes]
Improvement of SF-8 (QOL score)
Improvement of HADS score
Microbiota diversity (Shannon index, Chao1 index, weighted and unweighted UniFrac distances)
Prediction of the functional compositon of a metagenome using PICRUSt
Improvement of IBS-SI score in stratified analysis by each of the following 6 factors (more/less) at baseline
Correlation coefficient between the improvement of IBS-SI score and each increment of the following 6 factors at baseline to 4 weeks
[Six factors]
a. the genus Bifidobacterium (%)
b. the genus Veillonella (%)
c. the genus Lactobacillus (%)
d. the phylum Firmicutes : Bacteroides ratio
e. Shannon index
f. Chao1 index
