INSYTEInvestigation of the Effects of a Synbiotic on Liver Fat, Disease Biomarkers and Intestinal Microbiota in Non-alcoholic Fatty Liver Disease

Date de début de l'étude : 1 décembre 2013

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).
