Title: Investigation of the Effects of a Synbiotic on Liver Fat, Disease Biomarkers and Intestinal Microbiota in Non-alcoholic Fatty Liver Disease
Brief Summary: 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.


Options:
A: Inclusion Criteria:

* Patients with acute myocardial infarction discharged from hospital alive

Exclusion Criteria:

* Being part of another randomized trial
* Documented intolerance for omega-3 fatty acids
* Additional disease state that is thought to be incompatible with compliance to the study drugs
* Additional disease state thought to reduce survival for the follow-up time of 2 years
B: 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).
C: * This study is open to all VITAL participants (NCT 01169259). Population includes men 50 years of age or older and women 55 years of age or older in the United States
* Participants who live in selected metropolitan areas of the U.S. (where we set up the infrastructure for clinic or home visits), are eligible for pulmonary function measurements.
D: Inclusion Criteria:

* Multiple risk factors:

  * diabetes,
  * age =\> 65 years,
  * male sex,
  * hypertension,
  * hypercholesterolemia,
  * smoking,
  * obesity,
  * family history of premature cardiovascular disease;
* Previous manifestations of atherosclerotic disease (ischemic stoke, transient ischemic attack \[TIA\], peripheral artery disease, previous arterial revascularisation procedures, angina pectoris)

Exclusion Criteria:

* Contraindications (known allergies to n-3 PUFA) or indications (previous myocardial infarction) for the treatment with n-3 PUFA
* Serious comorbidity with an unfavourable prognosis over the short term
* Expected non compliance over a long period of time
* Pregnancy
