Background: The goal of treating chronic hepatitis C virus (HCV) infection is sustained virologic response (SVR). There is concern that despite achieving SVR, replication-competent HCV may be sequestered at low levels within the liver and could theoretically reactivate with immunosuppression. We report transplantation of a HCV-seropositive liver donor, who achieved SVR, into a seronegative patient without HCV reactivation despite profound immunosuppression.

Introduction: About 60% to 85% of people infected with hepatitis C virus will go on to develop chronic hepatitis C, which is now believed to affect 3% of the world's population.

Methods And Outcomes: We conducted a systematic overview and aimed to answer the following clinical questions: What are the effects of interferon-free treatments in treatment-naïve people with chronic hepatitis C infection without cirrhosis? What are the effects of interferon-free treatments in treatment-naïve people with chronic hepatitis C infection with cirrhosis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2014 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this review).

Results: After deduplication and removal of conference abstracts, 30 records were screened for inclusion in the review.

Background: The current treatment rate for chronic hepatitis C virus (HCV) infection is suboptimal despite the availability of efficacious antiviral therapy.

Objective: To determine the rate, delay and predictors of treatment in patients with chronic HCV infection.

Methods: A retrospective chart review of chronic HCV patients who were being evaluated at a tertiary hepatology centre in Vancouver, British Columbia, was performed.

Between 2001 and 2011, the standard of care for chronic hepatitis C virus (HCV) infection was a combination of pegylated interferon (PEG-IFN) and ribavirin (RBV). In May 2011, boceprevir and telaprevir, two first-generation NS3/4A protease inhibitors, were approved in combination with PEG-IFN and RBV for 24 to 48 weeks in hepatitis C virus genotype 1 infections. In December 2013, simeprevir, a second-generation NS3/4A protease inhibitor, was approved for use with PEG-IFN and RBV for 12 weeks in genotype 1, while sofosbuvir, a NS5B nucleotide polymerase inhibitor, was approved for use with PEG-IFN and RBV for 12 weeks in genotypes 1 and 4, as well as with RBV alone for 12 weeks in genotype 2 and for 24 weeks in genotype 3.
