Abstract and Introduction
Abstract
Objectives To determine whether older adults with the hepatitis C virus (HCV) achieve a sustained viral response (SVR) after treatment with direct-acting antiviral therapy.

Participants Individuals aged 80 and older with chronic HCV infection (N = 253; n = 213 with cirrhosis, n = 40 with advanced fibrosis).

Measurements
We investigated the efficacy, safety, and global clinical effect of treatment with different combinations of direct antiviral agents (DAAs). Participants with cirrhosis were staged according to Child-Pugh-Turcotte class, Model for End-Stage Liver Disease score, and the D'Amico staging system. The type and number of comorbidities at baseline and hepatic and nonhepatic events during follow-up were registered.

Results
Ninety-five percent of participants with cirrhosis and 95% of those with advanced fibrosis attained SVR. The rate was independent of sex, HCV genotype, and treatment schedule. During a mean follow-up of 14 ± 4 months (range 5–23 months), 34 events occurred in 27 participants: 10 hepatocellular carcinomas, 12 hepatic decompensations, 9 nonhepatic events, 3 deaths. Multivariate analysis of risk factors for experiencing adverse events during follow up showed that participants in D'Amico Stages 4 and 5, with a baseline serum albumin level of 3.5 mg/dL or less, and 3 or more comorbidities were the most at risk.

Conclusion
In a real-world setting, DAAs are safe and effective in older adults with HCV-related advanced fibrosis or cirrhosis. Individuals with preserved albumin synthesis and fewer than 3 comorbidities at baseline have the most to gain from long-term DAA therapy.

Severe fibrosis improves in most patients after hepatitis C cure but persists in a quarter


Severe fibrosis improves in most patients after hepatitis C cure but persists in a quarter

Hepatitis C virus (HCV)-related liver fibrosis improves significantly in the majority of patients with pre-treatment advanced fibrosis or cirrhosis after treatment resulting in a sustained virological response, Swedish investigators report in the Journal of Viral Hepatitis.

However, advanced fibrosis persisted in a quarter of patients and worsened in a small subset of patients, showing the need for regular monitoring after successful HCV therapy. Pre-treatment cirrhosis, older age and high body mass index were risk factors for the persistence of advanced cirrhosis.

“Our study shows that the vast majority of our 269 patients with pre-treatment advanced fibrosis or cirrhosis improved their fibrosis during long-term follow-up after SVR,” comment the researchers. “A minority, however, continued to have advanced fibrosis even after more than 5-10 years follow-up. In this subset of patients, a point of no return for advanced liver fibrosis might have been reached, where improvement is not possible.”

Abstract
Background
Ombitasvir/Paritaprevir-ritonavir (OBT/PTV-r) plus Ribavirin (RBV) for 12 weeks in hepatitis C virus (HCV) genotype 4 patients with advanced fibrosis has been only investigated in clinical trials.

Aims
To assess safety and efficacy of OBT/PTV-r + RBV for 12 weeks in real-life HCV-4 patients with advanced fibrosis.

Methods
HCV-4 patients with advanced fibrosis consecutively receiving OBT/PTV-r + RBV for 12 weeks in a single center were enrolled. Fibrosis was staged by transient elastography (TE) (F3: ≥10 kPa; F4 ≥11.9 kPa) or histologically. Sustained virological response (SVR) was defined as undetectable HCV-RNA 12 weeks post-treatment.

Results
Between January 2016 and February 2017, 49 HCV-4 patients were included: median age 54 (39-72) years, 84% males, 59% Egyptians, 35% fibrosis F3 and 65% F4, all Child Pugh class A. Median RBV dose was 1,200 (200-1,200) mg/day. At ITT analysis, 47 (96%) patients achieved an SVR (100% at PP analysis). SVR was not affected by ancestry (Egyptian vs. Italian 97% vs. 95%, p = 1.0), fibrosis stage (F3 vs. F4 100% vs. 94%, p = 0.53), presence of baseline resistance associated substitutions (RASs) or RBV reduction.

Conclusions
We report 100% SVR with 12-weeks of OBT/PTV-r + RBV in HCV-4 patients with advanced liver disease, including compensated cirrhotics.

Understanding Spontaneous Hepatitis C Virus Clearance
FEBRUARY 13, 2018
Elizabeth Kukielka, PharmD

Among patients in the acute phase of hepatitis C virus (HCV) infection, a portion will spontaneously clear the infection without treatment, and HCV RNA will completely disappear from the serum. Estimates from various studies project that anywhere from 20% to 30% of patients will spontaneously clear HCV, with the biggest factors being sex, ethnicity, immune status, and genetics.

Abstract
Introduction
Achievement of the 2030 World Health Organisation (WHO) global hepatitis C virus (HCV) elimination targets will be underpinned by scale-up of testing and use of direct-acting antiviral treatments. In Australia, despite publically-funded testing and treatment, less than 15% of patients were treated in the first year of treatment access, highlighting the need for greater efficiency of health service delivery. To this end, non-invasive fibrosis algorithms were examined to reduce reliance on transient elastography (TE) which is currently utilised for the assessment of cirrhosis in most Australian clinical settings.

Materials and methods
This retrospective and prospective study, with derivation and validation cohorts, examined consecutive patients in a tertiary referral centre, a sexual health clinic, and a prison-based hepatitis program. The negative predictive value (NPV) of seven non-invasive algorithms were measured using published and newly derived cut-offs. The number of TEs avoided for each algorithm, or combination of algorithms, was determined.

Results
The 850 patients included 780 (92%) with HCV mono-infection, and 70 (8%) co-infected with HIV or hepatitis B. The mono-infected cohort included 612 men (79%), with an overall prevalence of cirrhosis of 16% (125/780). An ‘APRI’ algorithm cut-off of 1.0 had a 94% NPV (95%CI: 91–96%). Newly derived cut-offs of ‘APRI’ (0.49), ‘FIB-4’ (0.93) and ‘GUCI’ (0.5) algorithms each had NPVs of 99% (95%CI: 97–100%), allowing avoidance of TE in 40% (315/780), 40% (310/780) and 40% (298/749) respectively. When used in combination, NPV was retained and TE avoidance reached 54% (405/749), regardless of gender or co-infection.

Conclusions
Non-invasive algorithms can reliably exclude cirrhosis in many patients, allowing improved efficiency of HCV assessment services in Australia and worldwide.

Abstract
Around 71 million people are chronically infected with HCV worldwide. HCV antiviral drug development has been remarkable. The availability of pangenotypic direct-acting antivirals with excellent efficacy and good tolerability profiles offer a unique opportunity to achieve HCV elimination worldwide. IFN-free DAA combinations can now cure HCV in more than 95% of patients with HCV infection after 8-12 weeks of treatment. Programmes to eliminate HCV must include increased screening (risk-based and universal), linkage to care, as well as increased access to treatment worldwide. In this paper, we will review the available data on recently approved direct-acting antiviral agents, with sustained virological response that reaches almost 100%.

Abstract
The elimination of hepatitis C virus (HCV) has been made possible through the availability of new antiviral drugs which may now be administered to all patients with HCV infection, even those with decompensated cirrhosis. The goal of the World Health Organization (WHO) is to reduce the incidence of chronic hepatitis infection from the current 6-10 million to 0.9 million cases of chronic infections by 2030, and annual deaths from 1.4 million to fewer than 0.5 million. Achieving these targets will require full implementation of epidemiological knowledge of HCV infection, screening and testing practices and strategies to link HCV patients to care. This review will focus on the current state of knowledge in the epidemiology of HCV and what can be done to increase patient awareness and reduce the barriers to treatment. Furthermore, we will discuss the role of HCV clearance on the control of HCV-related outcomes

For Viral Hepatitis Elimination One Size Does Not Fit All
Jeffrey Lazarus
12 February 2018

“For elimination, one size does not fit all” was a refrain repeated in a number of different ways throughout the presentations and discussions at the European Association for the Study of the Liver (EASL) Monothematic conference on “Striving towards the elimination of HCV infection” that has just come to a close in Berlin.

Whether in discussions about prevention, interventions in drug users, improving linkage to care, or treatment itself, attendees agreed that there is no golden ticket for hepatitis C elimination. However, there are a number of evidence-based strategies for impact that were presented very effectively by over 30 speakers in the six thematic panel sessions.
