Vesale Pharmaceutica27 enrolled

Overview

The aim of the study is to evaluate the impact of a synbiotic containing fructo-oligosaccharides (FOS) and Bifidobacteria (VES002 LMG P-28149) on intestinal transit in middle-aged subjects characterized by a low number of defecations per week.

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.

Outcomes

Primary Outcomes

intestinal transit

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

Time frame: daily evaluation (day-14 to day 30)

Secondary Outcomes

stool consistency

self-assessment using the Bristol Stool Form Scale

Time frame: daily evaluation (day-14 to day 30)

evaluation of quality of life

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)

Time frame: day 0 and day 30

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

Evaluation based on VAS ( 0 - 100mm). 0 for no pain and 100 for unbearable pain
