BACKGROUND AND AIMS Risk stratification after cure from hepatitis C virus (HCV) infection remains a clinical challenge. We investigated the predictive value of noninvasive surrogates of portal hypertension (liver stiffness measurement [LSM] by vibration-controlled transient elastography and von Willebrand factor/platelet count ratio [VITRO]) for development of hepatic decompensation and hepatocellular carcinoma in patients with pretreatment advanced chronic liver disease (ACLD) who achieved HCV cure. APPROACH AND RESULTS A total of 276 patients with pretreatment ACLD and information on pretreatment and posttreatment follow-up (FU)-LSM and FU-VITRO were followed for a median of 36.6 months after the end of interferon-free therapy. FU-LSM (area under the receiver operating characteristic curve [AUROC]: 0.875 [95% confidence interval [CI]: 0.796-0.954]) and FU-VITRO (AUROC: 0.925 [95% CI: 0.874-0.977]) showed an excellent predictive performance for hepatic decompensation. Both parameters provided incremental information and were significantly associated with hepatic decompensation in adjusted models. A previously proposed combined approach (FU-LSM < 12.4 kPa and/or FU-VITRO < 0.95) to rule out clinically significant portal hypertension (CSPH, hepatic venous pressure gradient ≥10 mm Hg) at FU assigned most (57.3%) of the patients to the low-risk group; none of these patients developed hepatic decompensation. In contrast, in patients in whom FU-CSPH was ruled in (FU-LSM > 25.3 kPa and/or FU-VITRO > 3.3; 25.0% of patients), the risk of hepatic decompensation at 3 years following treatment was high (17.4%). Patients within the diagnostic gray-zone for FU-CSPH (17.8% of patients) had a very low risk of hepatic decompensation during FU (2.6%). The prognostic value of this algorithm was validated in an internal (n = 86) and external (n = 162) cohort. CONCLUSION FU-LSM/FU-VITRO are strongly and independently predictive of posttreatment hepatic decompensation in HCV-induced ACLD. An algorithm combining these noninvasive markers not only rules in or rules out FU-CSPH, but also identifies populations at negligible versus high risk for hepatic decompensation. FU-LSM/FU-VITRO are readily accessible and enable risk stratification after sustained virological response, and thus facilitate personalized management.
