Management and treatment of injection drug users with hepatitis C virus (HCV) infection and HCV/human immunodeficiency virus coinfection

Injection drug use is the major mode of hepatitis C virus (HCV) transmission in developed countries. Despite this, relatively few current and recovering injection drug users (IDUs) have received HCV treatment. Studies among individuals with a recent history of injection drug use or those receiving drug dependency treatment have provided evidence that these groups can be successfully treated for chronic HCV infection. These studies have provided the impetus to change guidelines for treatment of current and recovering IDUs, with a move toward individualized HCV treatment assessment and the removal of defined periods of illicit drug use abstinence. Strategies to improve access to HCV treatment for current and recovering IDUs include drug dependency treatment education and training for hepatologists and other HCV treatment physicians, HCV treatment education and training for addiction medicine physicians, development of multidisciplinary clinics, and peer-based eduction and support for individuals considering and receiving HCV treatment.
