Liver stiffness measured by transient elastography correlates with fibrosis area in liver biopsy in patients with chronic hepatitis C

2009 Hepatology Research 39;7 (675-684)

AIM: Liver stiffness (LS) measured by transient elastography (TE) has been reported to correlate with liver fibrosis, which is usually semiquantitatively assessed. In the present study, the fibrosis area was measured by image analysis software in liver biopsy specimens and its correlation with LS was assessed. METHODS: LS was measured by TE in all 165 patients with chronic hepatitis C virus (HCV) infection who underwent liver biopsy consecutively in Fujita Health University Hospital from July 2004 to September 2007. RESULTS: Fibrosis area was significantly correlated with fibrosis stage as assessed by the Metavir score (rho = 0.733, P or = 2, 3.1% for F > or = 3, and 3.8-6.4% for F4. LS was significantly correlated with fibrosis stage (rho = 0.734, P or = 2, 9.6 kPa for F > or = 3 and 11.6-16.9 kPa for F4. Multiple linear regression analysis selected fibrosis area (P = 0.0002), alanine aminotransferase (ALT) (P = 0.0237), gamma-glutamyltransferase (gamma-GTP) (P = 0.0114), prothrombin time (P = 0.0114) and hyaluronic acid (P
