Chronic infection with hepatitis C virus (HCV) is a leading cause of end-stage liver disease and is the most common indication for liver transplantation in the United States. Because of shared risk factors, individuals living with HIV infection are disproportionately affected by HCV. Moreover, co-infection with HIV accelerates the natural history of chronic HCV infection, increasing the risk of cirrhosis, hepatocellular carcinoma, hepatic decompensation, and death. Highly effective medications such as direct-acting antivirals (DAA) to cure HCV are now available and have the potential to profoundly improve the health of HIV-HCV-co-infected individuals. However, addressing the many gaps in the HCV care cascade is necessary to fully achieve the benefits of these drugs. This chapter reviews the natural history of HIV-HCV co-infection, the psychiatric comorbidities associated with HCV infection, the evolution of HCV treatment, and the barriers to care that HIV-HCV-co-infected individuals continue to face.
