['Transient elastography (TE) is a validated non-invasive tool to evaluate hepatic fibrosis in patients with hepatitis C virus (HCV) infection. Whether TE may sense changes of liver fibrosis following therapeutic HCV eradication has never been evaluated.', '37 HCV cirrhotics with paired pre- and post-sustained virological response (SVR) liver biopsies (LB) underwent TE at the time of post-SVR LB. Liver fibrosis was staged with the METAVIR scoring system and the area of fibrosis (%) was assessed morphometrically.', 'Thirty-three patients had valid TE measurements after 61 (48-104) months from an SVR, and 20 (61%) of them had cirrhosis regression. On post-SVR LB, the median area of fibrosis was 2.3%, being significantly reduced from baseline (p<0.0001). Median TE value was 9.8 kPa being lower in regressed vs. not regressed patients (9.1 kPa vs. 12.9 kPa, p=0.01). TE was <12 kPa in 5 (38%) F4 patients and in 19 (95%) ≤F3 patients (p=0.0007). The diagnostic accuracy of TE for diagnosing F4 after treatment was 61% sensitivity, 95% specificity, 12.3 LR+, 0.4 LR-, and AUROC 0.77. A significant correlation was found between TE and both fibrosis stage (r=0.56; p=0.001) and morphometry (r=0.56, p=0.001) as well as between fibrosis stage and area of fibrosis (r=0.72, p=0001).'] Is the diagnostic accuracy of Fibroscan for cirrhosis influenced by liver morphometry in HCV patients with a sustained virological response?
