Who may be able to join

  • Both men and women
  • Age > 18 years

About this study

Official title: Investigation of the Effects of a Synbiotic on Liver Fat, Disease Biomarkers and Intestinal Microbiota in Non-alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease (NAFLD) is a liver condition in which fat builds up in the liver not caused by alcohol. The liver is an organ that is not designed to build up fat. NAFLD is common in people who have too much body fat in their abdomen or who have diabetes (high blood sugar), but does not always exist with these conditions. NAFLD can also occur in thin people too. NAFLD can be harmful to the liver and may cause the liver to fail over time. NAFLD may also cause adult (or type 2) diabetes and also heart disease. In people who already have diabetes, NAFLD can cause glucose (sugar) levels to be too high.

Our intestines (guts) contain healthy bacteria and some harmful bacteria (bugs). This balance of healthy and harmful bugs is essential for the normal workings of our intestine to digest food. Providing these bacteria do not leak out into the blood they do not cause harm. If the balance of healthy to harmful bugs is upset, the harmful can cause problems and leak out into the blood. Because the liver is connected to the intestine by blood vessels the harmful bacteria can get to the liver and cause problems. These bacteria can cause the liver and the body to build up too much fat and might cause NAFLD and obesity. In this study, we will test the effects of a supplement (synbiotic) taken during the day, that contains a mixture of 'good' healthy bacteria (probiotic) and a sugar (prebiotic) that is not broken down and absorbed into the blood. We will test whether the synbiotic supplement has beneficial effects on the NAFLD liver condition and on factors linked to too much body fat, diabetes and heart disease.

Read the detailed description

We will recruit people with NAFLD who have been diagnosed as part of their NHS (National Health Service) care with having this condition. At present there is no treatment for this condition.

Purpose and design:

We are asking the research question: "Does the modulation of gut microflora with a synbiotic improve non-alcoholic fatty liver disease and the related risk factors for heart disease and type 2 diabetes?"

Presently there is no treatment for this liver condition. Research evidence suggests that a synbiotic supplement might be beneficial for this condition.

To address this research question we want to undertake a randomised double blind placebo controlled trial recruiting people who have been diagnosed with NAFLD.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SynbioticDietary supplement

    The synbiotic to be used is fructo-oligosacharide with a degree of polymerization < 10 at 4 g/twice a day (two sticks a day) plus Bifidobacterium animalis subsp. lactis BB-12 as minimum of 10 billion CFU/day (1 capsule a day).

  • MaltodextrinDietary supplement

What is being measured

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

  1. Change in Liver Fat

    Change in liver fat percent was calculated as the percent liver fat at the end of the study, minus the percent of liver fat prior to the intervention. Change in liver fat percent ranged from -60.6% (good) to + 33.7% (bad).

    Measured: baseline and 12 months

  2. Change in Enhanced Liver Fibrosis Score (ELF)

    Change in Enhanced Liver Fibrosis score (ELF) was calculated as ELF score at the end of the study minus ELF score prior to the intervention (at baseline). A decrease in the ELF score was considered good as it reflected a decrease in liver fibrosis, and an increase in ELF score was considered bad as it reflected an increase in liver fibrosis.

    Change in ELF scores ranged from -0.56 (good) to + 0.68 (bad).

    Measured: baseline and 12 months

  3. Change in NAFLD Fibrosis Score

    Change in NAFLD Fibrosis Score (NFS) was calculated as the NFS score at the end of the study, minus NFS score prior to the intervention (at baseline). A decrease in the NFS score was considered good because it reflected a decrease in liver fibrosis, and an increase in NFS score was considered bad, as it reflected an increase in liver fibrosis.

    Change in NFS scores ranged from -2.07 (good) to + 1.75 (bad)

    Measured: baseline and 12 months

  4. Change in Bifidobacterium Spp.

    The change in percent of Bifidobacteria spp was computed as the percent of Bifidobactera spp at the end of the study minus the percent of Bifidobacteria prior to the intervention (at baseline).

    A positive change in percent (e.g +0.1 to 7.0%) in Bifidobacteria spp. was considered good and a negative change in percent (e.g. -0.1 to -0.5%) in Bifidobacteria spp. considered bad. (Minimum = -0.5% (bad) and Maximum = +7.0% (good)).

    Measured: baseline and 12 months

What does the primary outcome measure?

Change in Liver Fat (time frame: baseline and 12 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01680640, which also lists 4 linked publications.

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.
