Direct Antiviral Agents for Hepatitis C Virus-associated Cryoglobulinaemia Vasculitis
An observational study of Vasculitis and Cryoglobulinemia, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.
Trial summary
Cryoglobulinemia are responsible for systemic vasculitis, and the most frequently targeted organs are the skin, joints, kidney and peripheral nervous system. Cryoglobulinemia vasculitides are associated with significant morbidity and mortality, and require therapeutic intervention. Read more about this study

About this study
Cryoglobulinemia are responsible for systemic vasculitis, and the most frequently targeted organs are the skin, joints, kidney and peripheral nervous system. Cryoglobulinemia vasculitides are associated with significant morbidity and mortality, and require therapeutic intervention. With the discovery of hepatitis C virus (HCV) as the etiologic agent for most cases of mixed cryoglobulinemia new opportunities and problems for crafting therapy of HCV mixed cryoglobulinemia (MC) have emerged. A new and major concern was the potential adverse effects that immunosuppressive therapy with glucocorticoids and cytotoxic drugs could have on an underlying chronic viral infection. Alternatively the discovery of HCV provided the opportunity to control HCV-MC with antiviral therapy based on the belief that the underlying infection was driving immune complex formation and resultant vasculitis. Inducing a sustained virologic and clinical response and minimizing the use of immunosuppressive drugs are the main goals in the treatment of patients with HCV-MC vasculitis. Aggressive antiviral therapy has been shown to induce a complete remission of HCV-MC in up to 70% of patients. New antiviral combination, Interferon (IFN)-free regimens have recently proved very high virological response rate and with a very good safety profile and now need to be evaluated in severe and/or refractory HCV-MC patient's population.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of participants with complete clinical response of cryoglobulinaemia vasculitis
The complete clinical response is defined by improvement of all the affected organs involved at baseline and the absence of clinical relapse. The skin and articular improvement will be evaluated clinically (i.e. disappearance of purpura and/or ulcers and/or skin necrosis, disappearance of arthralgia and/or arthritis). Renal improvement will be evaluated biologically (i.e. proteinuria <0.3g/24h, disappearance of hematuria and improvement of Glomerular filtration rate (GFR) > 20% at week 24 if GFR < 60 ml/min/1.73 m² at diagnosis). Peripheral neurological improvement will be evaluated clinically (i.e. improvement of pains and paraesthesia by visual analogue scales, improvement of muscular testing in case of motor impairment at baseline) and/or electrophysiologically (i.e. improvement of electromyogram abnormalities at week 24 compared to baseline). The neuropathy total symptom score-6 (NTSS-6) will be applied to evaluate individual neuropathy sensory symptoms.
Measured: At week 24
Secondary outcomes (3)
Number of participants with sustained virological response
A sustained virological response is defined by the absence of detectable serum HCV RNA twelve weeks after the end of antiviral therapy
Measured: At week 36
Number of participants with Immunological complete response
Immunological complete response is defined by negativation of cryoglobulin at week 36.
Measured: At week 36
rate of side effects
Measured: up to week 24
