Study of Alcohol-related Liver Disease in Europe
Sponsor: University Hospital, Lille
Summary
Alcohol-induced liver injury is made up of fatty liver, fibrosis and alcoholic hepatitis (AH), elementary lesions that may occur separately, simultaneously or sequentially in a same patient. Among these histological features, alcoholic hepatitis, a necro-inflammatory process is associated with the fastest fibrosis progression leading to cirrhosis in 40% of cases and a pivotal lesion driving increased risk of liver decompensation. The non-invasive methods for the diagnosis of fibrosis open new perspectives for a better understanding of the natural history of disease-progression from early injury to the cirrhotic stage, for the identification of subgroup patients at risk of developing cirrhosis at medium term and for proposing a strategy of screening of patients with extensive cirrhosis at risk of liver-threatening events. There is an urgent need to perform studies in asymptomatic heavy drinkers in order to identify cut-offs associated with significant risk of development of cirrhosis at medium term. Such objectives require large-scale screening of heavy drinkers. Each of non-invasive methods have been tested to predict with of extensive fibrosis with a high predictive performance as shown below. A screening policy cannot be accepted without answering the following questions: a) are the requirements of public health screening fulfilled? b) Is the group of patients undergoing screening defined? c) is there a reliable method for of testing? Indeed, the detection of a disease is subject to certain public health requirements and may be proposed to health authorities only if it modifies the management of subjects screened. In the specific case of mass screening of liver fibrosis in heavy drinkers, only the detection of extensive fibrosis could fulfill this criterion because of the potential survival benefit resulting from the screening of hepatocellular carcinoma (HCC) in patients with extensive fibrosis. Indeed, recent studies have found that the probability of receiving curative treatment of HCC was significantly higher in patients who received a six-month surveillance ultrasound. Therefore, the detection of extensive fibrosis seems reasonable in the light of these studies when considering that the yearly risk of development of HCC in the subgroup of heavy drinkers with extensive fibrosis is approximately 3%. Taking into account the above scientific arguments, the most recent EASL clinical practical guidelines on ALD recommend longitudinal studies using non-invasive tools to evaluate screening of extensive fibrosis and disease progression in heavy drinkers.
