Background: Successful treatment of chronic hepatitis C with direct-acting antiviral agents (DAAs) is expected to lead to improvement in liver fibrosis in most of the patients. However, limited data are available on the improvement of advanced liver fibrosis and cirrhosis, measured by transient elastography after treatment. This study assessed the change in liver stiffness measurements after successful treatment with DAAs in patients with pre-treatment advanced fibrosis or cirrhosis., Methods: This observational retrospective cohort study included 514 mono-infected chronic hepatitis C patients, treated with all possible DAA-regimes in the Amsterdam region, the Netherlands. Liver stiffness was measured using FibroScan® at baseline and during follow-up. Cut-off values for staging liver fibrosis were ≥ 9.5 kPa for advanced fibrosis (F3) and ≥ 14.6 kPa for cirrhosis (F4)., Results: Liver stiffness decreased significantly from a median of 15.6 kPa (IQR 11.4-25.4) to 9.4 kPa (IQR 6.2-17.0) in 197 patients with pre-treated advanced fibrosis or cirrhosis. In 50.3% of these patients, liver stiffness improved to a value fitting with mild to moderate fibrosis (< 9.5 kPa, F0-F2) after successful treatment. Multivariate analysis demonstrated that a pre-treatment FibroScan® value of ≥ 20.0 kPa was associated with persisting advanced fibrosis or cirrhosis after treatment (OR 29.07, p < 0.001)., Conclusion: Liver stiffness improves significantly after successful direct-acting antiviral agent treatment in chronic hepatitis C patients with advanced fibrosis or cirrhosis prior to DAA treatment. Long-term outcomes regarding occurrence of hepatocellular carcinoma (HCC) in these patients are required to determine whether they can be safely discharged from HCC surveillance.

Chronic hepatitis C virus (HCV) infection is a global public health issue, which is associated with high rates of morbidity and mortality. The development of direct acting antivirals (DAAs) has transformed treatment: they offer us highly-effective therapy with superior tolerability compared to interferon-containing regimens. In 2016, the World Health Organization (WHO) therefore adopted several ambitious viral hepatitis elimination targets, aiming for a 90% reduction in new infections and a 65% reduction in mortality by 2030. The ultimate goal is to eliminate HCV completely. It is reasonable that these goals may be achieved in the Netherlands due to the low prevalence of chronic HCV, the availability of DAAs, and excellent healthcare infrastructure. This paper describes a national effort to curtail the HCV epidemic in the Netherlands through an HCV retrieval and linkage to care project (CELINE: Hepatitis C Elimination in the Netherlands).

Background & Aims: Prevalence of hepatitis C virus (HCV) infection in the Netherlands is low (anti-HCV prevalence 0.22%). All-oral treatment with direct-acting antivirals (DAAs) is tolerable and effective but expensive. Our analysis projected the future HCV-related disease burden in the Netherlands by applying different treatment scenarios., Methods: Using a modelling approach, the size of the HCV-viraemic population in the Netherlands in 2014 was estimated using available data and expert consensus. The base scenario (based on the current Dutch situation) and different treatment scenarios (with increased efficacy, treatment uptake, and diagnoses) were modelled and the future HCV disease burden was predicted for each scenario., Results: The estimated number of individuals with viraemic HCV infection in the Netherlands in 2014 was 19,200 (prevalence 0.12%). By 2030, this number is projected to decrease by 4 5% in the base scenario and by 85% if the number of treated patients increases. Furthermore, the number of individuals with hepatocellular carcinoma and liver-related deaths is estimated to decrease by 19% and 27%, respectively, in the base scenario, but may both be further decreased by 68% when focusing on treatment of HCV patients with a fibrosis stage of ≥ F2., Conclusions: A substantial reduction in HCV-related disease burden is possible with increases in treatment uptake as the efficacy of current therapies is high. Further reduction of HCV-related disease burden may be achieved through increases in diagnosis and preventative measures. These results might inform the further development of effective disease management strategies in the Netherlands.

Introduction: Interferon-g-inducible protein-10 (IP-10) serum levels are associated with IL28B genotype and may predict response to interferon÷ribavirin-based therapy in chronic hepatitis C patients. Our aim was to relate IP-10 levels before and during treatment to treatment outcome, viral HCV-RNA kinetics and IL28B genotype., Patients and Methods: A cohort of chronic hepatitis C patients was treated with high-dose interferon for six weeks, followed by standard peginterferon÷ ribavirin for 24 or 48 weeks. IP-10 and HCV-RNA levels were frequently determined before, during and after treatment., Results: IP-10 levels increased from log2.56 pg÷ml at baseline to log3.48 pg÷ml at Day 1 and gradually diminished thereafter. IP-10 levels at any time point were not statistically different between patients with or without sustained viral response (SVR). Patients with IL28B CC genotype had significantly lower baseline IP-10 levels (p = 0.019) and a higher increase of IP-10 levels from baseline to Day 1 than patients with IL28B non-CC genotypes (p = 0.015). Patients with HCV-RNA decline &#8805; 2.28log10 at Day 1 had significantly lower baseline IP-10 levels (p = 0.016) and a higher increase of IP-10 levels from baseline to Day1 (p = 0.047) than patients with HCV-RNA decline of < 2.28log10 at Day 1., Conclusions: In patients treated with high induction dose interferon, IP-10 levels at any time point were not predictive for SVR. Low baseline IP-10 levels and a higher increase of IP-10 levels from baseline to Day 1 were associated with IL28B CC genotype and HCV-RNA decline &#8805; 2.28log10 at Day 1. This suggests that, in our cohort, for prediction of SVR the added value of IP-10 to IL28B genotype and early viral kinetics is limited.
