Chronic hepatitis C virus (HCV) infection is closely associated with a plethora of diseases, including cancers and autoimmune disorders. However, the distinct triggers and cellular networks leading to such HCV-derived diseases are poorly understood. Around 8% of the human genome consists of human endogenous retroviruses. They are usually silenced but can be reactivated by environmental conditions, including viral infections. Our current understanding indicates that the activation of one specific family—namely, HERV-K(HML-2)—is linked to distinct pathologies, including cancer and autoimmunity. In this study, we analyzed the transcription levels of HERV-K(HML-2) in 42 HCV-infected patients receiving direct-acting antiviral therapies. Samples from the start of treatment until 12 weeks post-treatment were investigated. Our results show increased HERV-K(HML-2) transcript levels in patients with HCV-derived liver cirrhosis throughout the observation period. Several clinical parameters specifying poor liver function are positively correlated with HERV-K(HML-2) expression. Of note, patients without a sustained viral clearance showed a drastic increase in HERV-K(HML-2) transcript levels. Together, our data suggest that increased HERV-K(HML-2) expression is correlated with reduced liver function as well as therapy success in HCV-infected patients.

Background: Hepatitis C (HCV) is a common cause of liver failure and liver cancer, and is a frequent indication for liver transplantation (LT). Until recently, a majority of transplanted patients were viraemic at the time of transplantation and they inevitably underwent recurrent infection of the graft. Prior to the availability of specific direct-acting antiviral (DAA) drugs, HCV infection was seldom successfully treated before or after transplantation. Key Messages: During the past 2 years, the use of interferon-free DAA therapy has transformed the management of patients post-LT and of patients on the transplant waiting list. DAA treatment post-LT can eradicate infection and normalize liver function tests in a majority of treated patients. An improvement in long-term graft and patient outcome can be anticipated. DAA treatment of patients with liver failure awaiting LT eliminates infection and is associated with an improvement in the liver function for a majority of treated patients. The majority still require transplantation, though some may improve sufficiently and quickly enough to be removed from the LT waiting list. Conclusions: Eventually, as greater numbers of patients with compensated cirrhosis are successfully treated with DAAs, HCV-associated liver failure may become an uncommon indication for LT.
