Treatment of hepatitis C infections with interferon: a historical perspective.

Abstract

Interferons were first described in 1957, but it was not until 34 years after their discovery that sufficient quantities of it were available for treatment of hepatitis C virus (HCV) infections, Clinicians now have an excellent understanding of the basis for the effectiveness of interferon alpha (IFN-α) in the therapy of this disease. Treatment with IFN-α is more efficient when it complemented by the antiviral ribavirin and the IFN-α is conjugated with polyethylene glycol to form peginterferon. In the near future treatment of HCV with IFN-α may involve new anti-HCV agents that are currently under development.
