Core Tip

Core Tip: The treatment of hepatitis C virus (HCV) infection has changed since direct-acting antivirals (DAAs) became available. DAA use has been extended to patients with advanced cirrhosis and severe comorbidities. Consequently, this review addresses the following questions: What benefits can be expected from eradicating HCV in patients who already have advanced liver disease? Are DAAs associated with an appreciable benefit in liver cancer? Can HCV treatment have favorable effects on the major concomitant disorders such as diabetes or cardiovascular disease? Is there any cause for concern when using DAAs in HCV patients with a concomitant hepatitis B virus infection?
