    Abstract:
    BACKGROUND: Transient elastography (FibroScan) is a simple and noninvasive method to assess liver fibrosis by measuring liver stiffness and therefore can be a promising tool to evaluate liver fibrosis and avoid liver biopsy. We prospectively assessed the performance of transient elastography in patients with recurrent hepatitis C virus after living donor liver transplantation, in comparison with the surrogate serum markers. METHODS: Fifty-six patients with recurrent hepatitis C virus after living donor liver transplantation, who underwent both liver biopsy and transient elastography were included in this study. The grade of liver fibrosis (the Scheuer classification) obtained by biopsy was compared to liver stiffness measured by the transient elastography. RESULTS: The fibrosis grades were as follows: F0, n=22; F1, n=13; F2, n=9; F3, n=7; and F4, n=5. Liver stiffness values ranged from 2.9 to 72.0 kPa. The optimal cutoff values were 8.8 kPa for F>or=1, 9.9 kPa for F>or=2, 15.4 kPa for F>or=3, and 26.5 kPa for F>or=4. The area under the receiver operator characteristic curve for the diagnosis of fibrosis (F>or=2) by transient elastography was 0.92, while that by hyaluronic acid, type 4 collagen, alanine aminotransferase, and the aspartate transaminase to platelets ratio index were 0.52, 0.62, 0.64, and 0.70, respectively. CONCLUSIONS: These data suggest that transient elastography is a simple, noninvasive and reliable tool to assess liver fibrosis in patients with recurrent hepatitis C virus after living donor liver transplantation.
