Fibroscan is a non invasive imaging investigation which measures liver stiffness, known to correlate well with liver scarring and cirrhosis on liver biopsy. Indocyanine green is an inert dye which is purely extracted from the blood by liver cells, and is hence an excellent marker of both liver cell function and overall liver blood flow. There is little data for either of these biomarkers regarding outcomes in alcoholic liver disease. We aim to establish the accuracy of these liver biomarkers in predicting important liver related outcomes (death, transplantation and hospital readmission with cirrhosis related consequences) in patients with severe (decompensated) alcoholic liver disease. Moreover, we will assess whether the serial measurement of biomarkers has any impact on alcohol abstinence, motivation or quality of life. Over an 18 month period, 125 consecutive hospital inpatients with decompensated alcoholic liver disease will undergo baseline biomarker measurement, routine blood and urine tests and qualitative questionnaires. These will be measured during their initial hospital admission (0 months) with subsequent repeat measurement during follow up visits at 1, 2, 4 and 6 months. Each study visit time will be in the region of 30-40 minutes to complete these investigations. The end of the study for individual patients will be patient death, liver transplantation or 6 month from study enrolment; whichever occurs first.
