Timing of Antiviral Therapy in Candidates for Liver Transplant for Hepatitis C and Hepatocellular Carcinoma

Recommendations of the Polish Group of Experts for HCV for the treatment of hepatitis C in 2020

The recommendations set out the principles of diagnosis and treatment of hepatitis C virus (HCV) infections according to the most recent knowledge. The main goal of therapy for HCV infection is to eliminate the virus from the body, which consequently leads to arrest of progress or regression of changes in the liver. Current version of the recommendations prioritise pangenotypic regimens and provide guidelines in special populations of patients, such as children, cirrhotics, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) coinfected, those with renal failure, hepatic decompensation and non-responders to previous therapies.

Timing of Hepatitis C Virus Treatment in Liver Transplant Candidates in the Era of Direct-acting Antiviral Agents

Chronic hepatitis C virus (HCV) infection remains the leading indication for liver transplantation (LT) in the United States. While most patients with chronic HCV infection remain asymptomatic, up to one-third develop progressive liver disease resulting in cirrhosis. LT is often the only curative treatment once significant hepatic decompensation develops. However, antiviral therapy for HCV infection has advanced markedly in the past 5 years with the discovery and approval of direct-acting antiviral agents. These new regimens are well tolerated, of short duration and highly effective, unlike the traditional treatment with pegylated-interferon and ribavirin. As achieving sustained virological response becomes increasingly attainable for a majority of HCV-infected patients, concerns have been raised regarding the optimal timing of treatment for HCV infection in the setting of end-stage liver disease and during the peri-transplant period. On one hand, HCV treatment may improve hepatic function and negate the need for LT in some, which is crucial given the scarcity of donor organs and mortality on the waiting list in certain regions. On the other hand, HCV treatment may result in lowering the priority for LT without improving quality of life, thereby delaying potentially curative LT surgery. This review evaluates the evidence supporting the use of direct-acting antiviral agents in the period before and following LT.
