About this study

Official title: A Randomized, Placebo-controlled, Double-blinded, Parallel-group, 5-week Study of the Dietary Fibers Intake (Inulin, Pectin, Beta-glucan, Galactooligosaccharides) Influence on the Gut Microbiota Composition and Cardiovascular Risk Factors

The randomized double-blinded placebo-controlled multicenter study will be held in parallel groups. During 5 weeks the efficacy of different endpoints as a measure of response to the daily intake of dietary fibers (8 g of either inulin, pectin, beta-glucan or galactooligosaccharides) will be evaluated. Gut microbiota composition, lipids levels, inflammation markers, microbiome metabolites, changes in quality of life and stool parameters will be assessed in order to predict individual response in participants without serious chronic diseases

Read the detailed description

A randomized double-blinded study will include 270 volunteers without clinical manifestations of chronic diseases. Participants will be randomized into one of five arms daily consuming one of the following: placebo (maltodextrin, 8 g), inulin (8 g), pectin (8 g), beta-glucan (8 g) or oligosaccharides (8 g).

The study will include a 5-day screening period and a 5-weeks intervention period.

During screening stage, a volunteer will complete a questionnaire, and the following measurements will be performed: blood levels of glycated hemoglobin, creatinine, lipids, C-reactive protein, anthropometric measurements, as well as cardiovascular risk will be assessed.

Before and after the intervention blood and stool samples will be collected to conduct the following analyses: an extended lipid spectrum analysis, high-sensitivity C-reactive protein, 16S rRNA gut microbiome sequencing, laboratory stool testing, stool fecal short-chain fatty acids analysis. Anthropometric measures, physical examination will be performed for each volunteer. The following questionnaires will be completed: dietary recall questionnaire, SF-36, the Rome Criteria for the Functional gastrointestinal disorders (functional constipation). The assessed scales will include Bristol stool scale, Hospital Anxiety and Depression Scale (HADS), Hamilton Rating Scale for Depression (HRSD).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Blood lipids levels

    LDL, HDL, TC, TG, apoB, Lp(a)

    Measured: Change from Baseline Blood lipids levels at 5th week

  2. Change in Gut microbiota composition

    Relative abundance of bacterial taxa according to 16S rRNA sequencing data

    Measured: Change from Baseline at 5th week

Secondary outcomes (7)
  1. Change in Fecal short-chain fatty acids

    Butyrate, propionate and acetate concentrations

    Measured: Change from Baseline at 5th week

  2. Change in High sensitive C-reactive protein

    Low-grade inflammation assessment

    Measured: Change from Baseline at 5th week

  3. Change in Stool consistency

    The Bristol stool scale is a diagnostic medical tool designed to classify the form of human faeces into seven categories.

    Measured: Change from Baseline at 5th week

  4. Change in Stool frequency

    Rome criteria questionnaire. The Rome IV criteria for the diagnosis of irritable bowel syndrome require that patients have had recurrent abdominal pain on average at least 1 day per week during the previous 3 months that is associated with two or more of the following : Related to defecation (may be increased or unchanged by defecation)

    Measured: Change from Baseline at 5th week

  5. Change in Body Composition

    Bioelectrical impedance analysis

    Measured: Baseline and 5th week

  6. Change in Quality of Life: SF-36 questionnaire

    According to SF-36 questionnaire The Medical Outcomes Short-Form 36-Item Health Survey (SF-36) It is a self-administered questionnaire comprising 36-items measuring eight dimensions of general HRQOL: physical functioning (10 items), role limitation due to physical health problems (4 items), bodily pain (2 items), general health perceptions (5 items), vitality (4 items), social functioning (2 items), role limitations due to emotional problems (3 items), and general mental health (5 items). In addition to scores for individual dimensions, two summary scores assessing physical and mental dimensions of health and well-being can also be calculated: Physical Component Summary (PCS) score and the Mental Component Summary (MCS) score, respectively

    Measured: Change from Baseline at 5th week

  7. Change in Psychological distress

    Hospital Anxiety and Depression Scale (HADS) Patients anxiety and depression will be assessed using the HADS : Hospital Anxiety and Depression scale.

    Scores of the HADS scale can be defined as:

    By adding the points of the answers: 1, 3, 5, 7, 9, 11, 13: we obtain the "Total A" which corresponds to the measure of the anxiety, then:

    7 or less: absence of symptomatology; 8 to 10: doubtful symptomatology; 11 and above: certain symptomatology.

    By adding the points of the answers: 2, 4, 6, 8, 10, 12, 14: we obtain the "Total B" which corresponds to the measure of the depression, then:

    7 or less: absence of symptomatology; 8 to 10: doubtful symptomatology; 11 and above: certain symptomatology. The minimal score is 0 and the maximal total score is 42.

    Measured: Change from Baseline at 5th week

Questions about this trial

What is this clinical trial studying?

A study testing Maltodextrin, Inulin and Pectin in people with Microbiome and Metabolic Syndrome, run by Atlas Biomed at 1 site in Russia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 12 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Blood lipids levels (time frame: Change from Baseline Blood lipids levels at 5th week). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2021.
