Non-invasive markers of liver fibrosis have been recently developed as a possible alternative to liver biopsy. The clinical management of hepatic diseases is dependent on the extent of liver fibrosis. Liver biopsy remains the gold standard but severe complications are found in about 0.5% of cases. Studies involving sequential liver biopsies are impractical, costly, and risky. Therefore non-invasive markers of liver fibrosis could be useful. These drawbacks justify an intensive research on non-invasive alternatives. Several serum markers are either directly involved in fibrosis remodelling or are indirectly associated with the presence of significant liver fibrosis. More recently, fibrosis scores calculated from statistical models have been described. This review describes the role of non-invasive markers in assessing hepatic fibrosis in both HCV mono-infected and HIV/HCV co-infected subjects.
