Elastography is unable to exclude cirrhosis after sustained virological response in HCV-infected patients with advanced chronic liver disease

Background: liver fibrosis and transient elastography (TE) correlation in hepatitis C virus (HCV)-infected patients with compensated advanced chronic liver disease (cACLD) after the sustained virological response (SVR) is unknown. Aims: to evaluate TE accuracy at identifying cirrhosis 3 years after...

Description
Summary:Background: liver fibrosis and transient elastography (TE) correlation in hepatitis C virus (HCV)-infected patients with compensated advanced chronic liver disease (cACLD) after the sustained virological response (SVR) is unknown. Aims: to evaluate TE accuracy at identifying cirrhosis 3 years after HCV-eradication. Methods: prospective, multi-centric study including HCV-cACLD patients before direct-acting antivirals (DAA). Diagnostic accuracy of TE (area under ROC, AUROC) to identify cirrhosis 3 years after SVR was evaluated. Results: among 746 HCV-infected patients (95.4% with TE ≥10 kPa), 76 (10.2%) underwent a liver biopsy 3 years after SVR. Before treatment, 46 (63%) showed a TE>15 kPa. The TE before DAA was the best variable for predicting cirrhosis (METAVIR, F4) after SVR (AUROC = 0.79). Liver function parameters, serological non-invasive tests (APRI and FIB-4), and TE values improved after SVR. However, liver biopsy 3 years after HCV elimination (median time = 38.4 months) showed cirrhosis in 41 (53.9%). Multivariate analysis (OR (95% CI), P) showed that HCV-genotype 3 (20.81 (2.12-201.47), .009), and TE before treatment (1.21 (1.09-1.34), <.001) were the only variables associated with cirrhosis after SVR. However, the accuracy of TE after SVR was poor (AUROC = 0.75) and 6 (27.3%) out of 22 patients with a TE <8 kPa had cirrhosis. Similar results were found with APRI and FIB-4 scores. Conclusions: cirrhosis is present, 3 years after SVR, in more than half of HCV-cACLD patients even with the normalisation of liver function parameters, serological non-invasive tests and TE values. The low diagnostic accuracy of non-invasive methods after SVR reinforces the need for long-term surveillance.
