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.

Eligibility | Inclusion Criteria: - Both men and women - Age > 18 years - Liver fat diagnosed on normal clinical grounds including in most cases liver assessed by Kleiner scoring system to classify severity, with no known aetiological factors for underlying liver disease (e.g. exclusion of hepatitis A, B & C, primary biliary cirrhosis, autoimmune hepatitis, haemochromatosis). Last liver biopsy will be within 3 years of recruitment to the study. - Liver fat diagnosed by ultrasound, CT or magnetic resonance imaging (MRI) in patients who also have either diabetes and/or features of the metabolic syndrome, without evidence of known aetiological factors for underlying liver disease (e.g. exclusion of hepatitis A, B & C, primary biliary cirrhosis, autoimmune hepatitis, haemochromatosis). - Alcohol consumption = 14 units / week for women = 21 units / week for men. Exclusion Criteria: - Alcohol consumption > 15 units /week for women and > 22 units /week for men. - Decompensated acute or chronic liver disease. - A history of viral hepatitis, diarrhoea, diverticulosis, irritable bowel syndrome, inflammatory bowel diseases, coeliac disease (seropositivity for anti-endomysial immunoglobulin A antibodies; immunoglobulin A (IgA) EMA). - Previous bariatric or other abdominal surgery. - Continuous use of antibiotics that may change gut microflora, probiotics, or antisecretory drugs capable of causing achlorhydria within the 2 months preceding enrolment, or evidence of immunoglobulin A or immunoglobulin deficiency (both of which produce confounding effects during assessments of intestinal permeability and small intestinal bacterial overgrowth). |

Primary | 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). | baseline and 12 months | |
Primary | 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). |
baseline and 12 months | |
Primary | 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) |
baseline and 12 months | |
Primary | 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)). |
