About

Apart from Fibrotest, non-invasive markers have been validated only for chronic hepatitis C. However as for chronic C hepatitis, non invasive tests (Fibrotest and transient elastometry) are already used in current practice. The aim of this study is to validate the diagnostic value of FIBROSCAN by comparison with liver histology. FIBROSCAN will be also compared to Fibrotest and FIBROSCAN-Fibrotest association to each test alone in order to optimize this diagnostic strategy.

Studied variables will be significant fibrosis (≥ 2 in the METAVIR score) and presence of cirrhosis (score : F4). Diagnostic values of the scores will be expressed by sensitivity, specificity, positive and negative predictive values, and ROC curves. Areas under ROC curve of the scores will be compared using Z test.

Full description

Alcoholic liver disease (ALD) is highly prevalent and liver fibrosis and cirrhosis are asymptomatic for a long time. Liver biopsy in patients with ALD is designed to determine the prognostic of the liver lesions and to manage cirrhosis. Apart from Fibrotest, non-invasive markers have been validated only for chronic hepatitis C. However as for chronic C hepatitis, non invasive tests (Fibrotest and transient elastometry) are already used in current practice. The aim of this study is to validate the diagnostic value of FIBROSCAN by comparison with liver histology. FIBROSCAN will be also compared to Fibrotest and FIBROSCAN-Fibrotest association to each test alone in order to optimize this diagnostic strategy.

200 consecutive excessive drinkers with aminotransferase anomalies or suspicion of cirrhosis will be included in the study over a period of 2 years. All patient will have intercostal liver biopsy, assessment of the non-invasive biological scores of liver fibrosis and transient elastography.

Studied variables will be significant fibrosis (≥ 2 in the METAVIR score) and presence of cirrhosis (score : F4). Diagnostic values of the scores will be expressed by sensitivity, specificity, positive and negative predictive values, and ROC curves. Areas under ROC curve of the scores will be compared using Z test. Multivariate analyses will be used to identify the scores with an independent diagnostic value and therefore that could be associated.

This study will allow to select the non-invasive marker(s) with the best diagnostic values in order to identify early fibrosis in patients with ALD.
