About this study

Official title: The Use of a Probiotic Blend in Reducing Anthropometric Measurements and Improving Biochemical Parameters in Adults With Overweight and/or Obese

It is already known that dysbiosis, that is, qualitative and quantitative changes in the composition of the intestinal microbiota, can be associated with the development of a series of intestinal and extra-intestinal disorders. Dysbiosis is reported in irritable bowel syndrome, inflammatory bowel disease, colorectal cancer, allergic diseases, non-alcoholic steatohepatitis, arteriosclerotic diseases, neurological diseases and metabolic syndromes, mainly diabetes and obesity. Among the many factors that play a key role in obesity, a number of studies show the intestinal microbiota as an important contributor. Many studies carried out with probiotics have shown that their administration can be effective in the prevention and treatment of obesity. Furthermore, it is found that benefits for body weight, abdominal adiposity, anthropometric measurements and body composition are often associated with favorable metabolic effects.

Read the detailed description

Obesity is defined as excessive accumulation of body fat, caused by an energy imbalance. Approximately 13% of the world's adult population is obese, and in Brazil 19.8% of adults are obese. This disease is a risk factor for the development of other non-communicable chronic diseases (NCDs), such as: type 2 diabetes mellitus (DM2), dyslipidemia, cardiovascular diseases, musculoskeletal disorders and some types of cancer. It is a complex and multifactorial disease, which is why it is considered difficult to control and a cause for global concern. Among the causes of the disease, genetic, environmental and psychological factors can be mentioned, in addition to the interference of the intestinal microbiota, among others.

The interaction of the intestinal microbiota with the host has been studied through metabolomics, in order to understand the influence that the microbiota can exert on the functioning of the host organism. The study of the profile of low molecular weight metabolites of biological fluids such as serum/plasma and urine aims to understand the metabolic changes that occur in individuals with obesity, encompassing the understanding of the mechanisms of the disease.

Studies have shown differences in the metabolic profile of obese individuals compared to eutrophic individuals, with a positive correlation between body mass index (BMI) and increased concentrations of chain amino acids (BCAA) and glutamate. The gut microbiota appears to play a crucial role in host metabolism, being a pathway through which it leads to changes associated with obesity.

In this context, the intestinal microbiota can be modulated by prebiotics, probiotics and symbiotics, promoting changes in its composition, resulting in the regeneration of the intestinal barrier and, with that, ceasing metabolic endotoxemia and low-grade inflammation.

In addition, they have effects on the modulation of the immune system, regulating the production of pro and anti-inflammatory cytokines, reducing IR. Through these mechanisms, probiotics and symbiotics alter the microbiota profile of individuals leading to loss of body weight and metabolic parameters associated with obesity.

Several studies have shown beneficial effects of using probiotics on body weight, glycemic control, improvement in lipid profile and blood pressure (BP). However, there are controversies about which are the best strains for this purpose. There are five systematic reviews currently published with or without meta-analysis that address the effect of using different probiotics on body weight. Among the strains associated with weight loss and/or adiposity, L. plantarum associated with L. rhamnosus and hypocaloric diet stand out; L. plantarum with L. curvatus; L. gasseri; L. amylovorus; L. acidophilus and L. casei associated with phenolic compounds; or Lactobacillus mix.

What is being measured

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

  1. Body fat composition by Bioelectrical impedance analysis

    By Bioelectrical impedance analysis (BIA). This is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body and the voltage is measured in order to calculate impedance (resistance) of the body.

    Measured: three months

Secondary outcomes (9)
  1. Total cholesterol by blood analyses

    biochemical analyses before and after inclusion: Total cholesterol to be carried out in a reference laboratory. Total cholesterol will be measured in mg/dL

    Measured: three months

  2. quality of life questionnaire score

    quality of life and improvement of gastrointestinal symptoms by SF-36 scale (It comprises 36 questions that cover eight domains of health)

    Measured: three months

  3. Gastrointestinal Symptom Rating Scale (GSRS) questionnaire score

    GSRS scale: An interview-based rating scale consisting of 15 items for assessment of gastrointestinal symptoms

    Measured: three months

  4. Weight

    weight will be measured in kilograms

    Measured: three months

  5. height

    height will be measured in centimeters

    Measured: three months

  6. HDL levels by blood analyses

    biochemical analyses before and after inclusion: HDL to be carried out in a reference laboratory. HDL will be measured in mg/dL

    Measured: three months

  7. LDL levels by blood analyses

    biochemical analyses before and after inclusion: LDL to be carried out in a reference laboratory. LDL will be measured in mg/dL

    Measured: three months

  8. triglycerides levels by blood analyses

    biochemical analyses before and after inclusion: triglycerides to be carried out in a reference laboratory. triglycerides will be measured in ml/dL

    Measured: three months

  9. Glucose levels by blood analyses

    biochemical analyses before and after inclusion: glucose to be carried out in a reference laboratory. glucose will be measured in mg/dL

    Measured: three months

A Phase 2 study testing Probiotic blend in people with Obesity and Obesity; Endocrine, run by Universidade do Extremo Sul Catarinense - Unidade Academica de Ciecias da Saude at 1 site in Brazil.

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 4 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 21 Feb 2023. 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 Brazil. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body fat composition by Bioelectrical impedance analysis (time frame: three months). 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 21 Feb 2023.
