Liver Disease: Hepatitis C.

Approximately 4.1 million individuals in the United States have a history of hepatitis C virus (HCV) exposure, including 2.5 million with chronic infection. Screening guidelines recommend one-time, routine, opt out HCV screening for all individuals 18 years or older. Risk-based testing is recommended for specific individuals. Although many patients with chronic hepatitis C may progress to cirrhosis, end-stage liver disease, and hepatocellular carcinoma, early treatment can prevent development of these sequelae. Management of hepatitis C has simplified significantly, and primary care physicians now can monitor and provide treatment for most patients. Adults with chronic hepatitis C who do not have cirrhosis and have not received hepatitis C treatment previously are eligible for primary care-based treatment. These patients should undergo a comprehensive pretreatment evaluation to guide treatment planning. Patients typically are treated with one of two pangenotypic regimens: glecaprevir-pibrentasvir for 8 weeks or sofosbuvir-velpatasvir for 12 weeks. Virologic cure, defined as sustained virologic response (SVR) at 12 weeks after treatment completion, should be confirmed by an undetectable quantitative HCV RNA via polymerase chain reaction test performed 12 weeks or later after treatment completion. Management results in rates of virologic cure of greater than 95% across genotypes. Patients who do not achieve SVR at 12 weeks should be referred to a subspecialist experienced in management of treatment failure.
