Improved health-related quality of life after hepatitis C viraemic clearance among people who inject drugs may not be durable.

Successful direct-acting antiviral therapy for hepatitis C infection may not lead to a durable improvement in quality of life among people who inject drugs, although there may be a transient improvement around the time of sustained virologic response. Economic models of the impact of scaling-up treatment may need to include more conservative quality of life benefits over and above reductions in mortality, disease progression and transmission of infection.
