Detailed Description
Middle-aged subjects, who met ROME III criteria for constipation, received daily two sachets of either synbiotic or for 5 days, then they received daily 1 sachet for the next 25 days.
The primary endpoint of this trial is to evaluate the effect of supplementation in synbiotic containing fructo-oligosaccharides (FOS) and Bifidobacteria (VES002 LMG P-28149) on intestinal transit in middle-aged subjects characterized by a few bowel movements per week. The secondary endpoints are to evaluate both clinical criteria such as changes in stool appearance, quality of life and mood, relief and satisfaction of participants; and biological criteria such as changes in markers of gut function, low-grade chronic inflammation markers and gut microbiota composition. The safety of product use and compliance are also evaluated
Synbiotic group. The dietary supplement under study was composed of fructo-oligosaccharides - FOS: 4.95 gr / sachet and Bifidobacterium animalis lactis: VES002 (LMG P-28149): 5 billion / sachet. Sachets of powder were diluted in a in 200 ml of water at room temperature to be taken before breakfast. Doses were 2 sachets per day for the first 5 days and then 1 sachet per day for the next 25 days.
Placebo group. The placebo looked strictly identical to the synbiotic and contained only excipients (60% maltodextrin / 40% sucrose). Sachets of powder were diluted in a in 200 ml of water at room temperature to be taken before breakfast. Doses were 2 sachets per day for the first 5 days and then 1 sachet per day for the next 25 days.

|
Middle-aged subjects, who met ROME III criteria for constipation, received daily two sachets of synbiotic (Bifidobaterium animalis lactis Vesalius 002 and Fructo-Oligosaccharrides) for 5 days, then they received daily 1 sachet for the next 25 days

Placebo Comparator: Placebo group
A placebo was composed of maltodextrin (60%) and sucrose (40%) : 5 g /sachet (n =14)
|
Middle-aged subjects, who met ROME III criteria for constipation, received daily two sachets of placebo (maltodextrin and sucrose) for 5 days, then they received daily 1 sachet for the next 25 days

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
intestinal transit
Time Frame: daily evaluation (day-14 to day 30)
|
stool frequency and consistency were investigated through daily self-assessment using the Bristol Stool Form Scale (BSFS).
The BSFS classifies stools into 7 categories, including type 1, separate hard lumps, like nuts; type 2, sausage-shaped, but lumpy; type 3, like a sausage but with cracks on the surface; type 4, like a sausage or snake, smooth and soft; type 5, soft blobs with clear-cut edges; type 6, fluffy pieces with ragged edges, a mushy stool; type 7, watery, no solid pieces

stool consistency
Time Frame: daily evaluation (day-14 to day 30)
|
self-assessment using the Bristol Stool Form Scale
|
daily evaluation (day-14 to day 30)
|
evaluation of quality of life
Time Frame: day 0 and day 30
|
Mental and physical wellbeing were assessed before (d-14) and after intervention (d30) through the Short-Form 12-item (SF-12) questionnaire consisting of 12 questions relating to: physical health problems, bodily pain, general health perceptions, vitality (energy/fatigue), social functioning, role limitations and general mental health (psychological distress and psychological well-being)
|
day 0 and day 30
|
mood
Time Frame: daily evaluation (day-14 to day 30)
|
Mood alterations was investigated through daily self-assessment using the Brief Mood Introspection Scale (BMIS), consisting of 16 mood adjectives (Lively, Drowsy, Happy, Grouchy, Sad, Peppy, Tired, Nervous, Caring, Calm, Content, Loving, Gloomy, fed up, Jittery, Active)47.
Subjects were asked to circle the phrases describing their present mood (with XX = definitely do not feel; X = do not feel; V = slightly feel; VV = definitely feel on the diverse adjectives).

|
abdominal pain and intestinal discomfort
Time Frame: day -14 and day 30
