Long-term Efficacy of Interferon-Free Antiviral Treatment Regimens in Patients With Hepatitis C Virus-Associated Cryoglobulinemia Vasculitis

In small-size and short-term studies of hepatitis C virus-associated cryoglobulinemia vasculitis (HCV-CryoVas), patients had a higher rate of response and tolerance to direct-acting antiviral (DAA) agents than interferon-containing regimens. We collected follow-up data from a clinical trial to determine the long-term effectiveness and tolerance of all-oral, interferon-free DAA regimens in patients with CryoVas.
