Brief Summary
A systemic Vasculitis is found in 5 to 10% of HCV infected patients with mixed cryoglobulinemia (MC). It mainly involves the skin, peripheral nerve and the kidney and may be life threatening. Twenty to 30% of HCV-MC Vasculitis patients are resistant to conventional therapy (i.e. antiviral therapy and/or immunosuppressors) and still have an active disease. Thus, new therapeutic approaches are necessary in such patients. We recently described a regulatory T cell (Treg) deficiency in HCV-related Vasculitis patients. Immunomodulatory effects of interleukin-2 (IL-2) are well established, notably the preferential expansion of Treg able to suppress inflammatory responses mediated by CD4+ and CD8+ T cells.

Eligibility Criteria
You may qualify if:
- HCV+ patients with cryoglobulinemia Vasculitis
- resistant to conventional therapy (i.e. antiviral therapy and/or immunosuppressors).
- Vasculitis is defined according to international criteria: chronic HCV infection (HCV RNA+),
- serum cryoglobulin superior or equal to 0.05g/l in at least two determinations,
- presence of the triad purpura-arthralgia-asthenia and/or biopsy proven Vasculitis (kidney, nerve or skin).
