Liver stiffness regression after sustained virological response by direct-acting antivirals reduces the risk of outcomes.

ABSTRACT: The role of liver stiffness measurement (LSM) after sustained virological response (SVR) in HCV patients treated by direct-acting antivirals (DAAs) remains unclear. We aimed to evaluate LSM regression value after SVR and to identify risk factors associated with liver related complications (LRC) or death. This retrospective study analyzed patients with LSM ≥ 10 kPa with LSM by transient elastography pre-DAAs and post-SVR. Patients with previous hepatic decompensation were excluded. Medical records were reviewed to identify primary outcomes. Kaplan-Meier curves and time-to-event Cox proportional-hazard models were performed. 456 patients [65% female, 62 years (IQR 57-68)] were included. During a follow-up of 2.3 years (IQR 1.6-2.7), 28 patients developed 37 outcomes [rate = 29.0 (95% CI 20.0-42.0) per 1000 person-years]. The cumulative incidence of outcomes was significantly lower in patients who regressed LSM ≥ 20% [3.4% (95% CI 1.8-7.0) vs. 9.0% (5.5-14.5), p = 0.028]. In a multivariate Cox-model [HR(95% CI)], male gender [HR = 3.00 (1.30-6.95), p = 0.010], baseline albumin < 3.5 mg/dL [HR = 4.49 (1.95-10.34), p < 0.001] and baseline unfavorable Baveno-VI [HR = 4.72 (1.32-16.83), p = 0.017] were independently associated and LSM regression ≥ 20% after SVR had a trend to reduce the risk of LRC or death [HR = 0.45 (0.21-1.02), p = 0.058]. The use of simple parameters before DAAs and repetition of LSM post-SVR can identify patients with different risks for severe outcome after HCV eradication.

Project description:IntroductionThe genomic characteristics of hepatocellular carcinoma (HCC) after a sustained virological response (SVR) and its differences according to whether an SVR was achieved by treatment with direct-acting antivirals (DAA) or interferon (IFN) are still not fully understood.MethodsSixty-nine surgically resected HCCs from patients with hepatitis C virus infection were analyzed by gene expression profiling and whole-exome sequencing.ResultsAmong the 69 HCC patients, 34 HCCs in which an SVR was not achieved at the time of surgery were classified as HCV-positive, and 35 HCCs in which an SVR was achieved at the time of surgery were classified as HCV-SVR. According to the HCV treatment, 35 HCV-SVR HCCs were classified into two groups: eight tumors with DAA (HCV-SVR-DAA) and 24 tumors with interferon (HCV-SVR-IFN). The frequency of samples with ARID2 mutations was significantly lower in HCV-SVR than in HCV-positive tumors (p = 0.048). In contrast, the frequency of samples with PREX2 mutations was significantly higher in HCV-SVR samples than in HCV-positive samples (p = 0.048). Among the patients with HCV-SVR, the frequency of samples with TP53 mutations was significantly higher in HCV-SVR-DAA tumors than in HCV-SVR-IFN tumors (p = 0.030). TP53 inactivation scores in HCV-SVR-DAA tumors were found to be significantly enhanced in comparison to HCV-SVR-IFN tumors (p = 0.022). In addition, chromosomal instability and PI3K/AKT/mTOR pathway signatures were enhanced in HCV-SVR-DAA tumors. HCV-SVR-DAA was significantly associated with portal vein invasion (p = 0.003) in comparison to HCV-SVR-IFN.ConclusionOur dataset potentially serves as a fundamental resource for the genomic characteristics of HCV-SVR-DAA tumors. Our comprehensive genetic profiling by WES revealed significant differences in the mutation rate of several driver genes between HCV-positive tumors and HCV-SVR tumors. Furthermore, it was revealed that the frequency of samples with mutations in TP53 was significantly higher in HCV-SVR-DAA tumors than in HCV-SVR-IFN tumors.

Project description:BackgroundDirect-acting antivirals (DAA) have revolutionized hepatitis C treatment, with high sustained virological response (SVR) rates reported, even in historically difficult-to-treat groups. SVR is associated with a decreased risk of hepatocellular carcinoma (HCC), need for transplantation, and overall and liver-related mortality. Data from real-life cohorts on the medium- to long-term outcomes of patients with advanced liver disease and DAA-induced SVR are still missing.ObjectivesTo report and analyze the long-term outcomes of DAA-induced SVR in a real-life cohort of patients with advanced liver disease.MethodIn this retrospective, longitudinal, single-center study, we collected data from patients with chronic hepatitis C infection and advanced liver disease (cirrhosis or advanced fibrosis) that had initiated DAA treatment between February 2015 and January 2017.ResultsA total of 237 patients were included. A treatment completion rate of 98.7% and an SVR rate of 97.8% (intention to treat: 96.6%) were found. Of the 229 patients with SVR, 67.2% were cirrhotic (64.2% Child-Pugh class A; 3.1% Child-Pugh class B) and 32.8% had stage F3 fibrosis, with an average follow-up of 28 months. The overall mortality rate was 19/1,000 person-years and the liver-related mortality rate was 9.5/1,000 person-years. The hepatic decompensation incidence rate was 25/1,000 person-years and the HCC incidence rate was 11.6/1,000 person-years. There was a sustained increase in serum platelet values during up to 2 years of follow-up. A history of pretreatment decompensation and baseline platelet and albumin values were significantly associated with the occurrence of adverse liver events after the end of treatment.ConclusionsA DAA-induced SVR remains durable and is associated with an excellent clinical prognosis in patients with compensated advanced liver disease and with improvement or disease stabilization in decompensated patients. SVR is associated with a low risk of - yet does not prevent - HCC occurrence or disease progression, especially in the presence of other causes of liver injury. It is recommended that these patients be kept under surveillance.
