[Serum markers of non-invasive fibrosis in chronic hepatitis C virus infection].

MATTER: Liver biopsy is recommended for the management of patients infected by hepatitis C virus (HCV) and is currently the gold standard in assessing liver histology. It's an invasive test prone to complications with a morbidity rate of 0.3 to 0.6% and a mortality rate up to 0.05%. Since the last decade, researchers developed non invasifs biomarkers of liver fibrosis as an alternative to liver biopsy. These scores are based on different algorithms with various combinations of biomarkers issued from extra-cellular matrix, serum and cells. CURRENT EVENTS: The diagnostic performance of these scores, estimated by the AUROC for significant fibrosis (>F2), in patients with chronic hepatitis C reach 0.78 to 0.90 for the most accurate. In HIV-HCV co-infected patients and patients with hepatitis C cirrhosis the diagnostic performance of these scores reach 0.74 to 0.88 and 0.73 to 0.97 respectively. PERSPECTIVES: Liver fibrosis biomarkers constitutes an alternative to liver biopsy due to their non invasive approach, their easy reproducibility and accuracy. However, these scores must be used only after a validation in multicentric independent studies. The future is based on the comparison and validation of these scores after laboratory methods standardization.
