In autoimmune disorders (ADs), if Hepatitis C Virus (HCV) is present, immunosuppressive treatment could increase virus replication. Cyclosporine A (CsA), in standard therapeutic doses, has been proven able to inhibit HCV cyclophilin in vitro. Therefore CsA could improve the therapy of HCV patients with ADs. In these patients, we started an open pilot study to evaluate the safety of 3 mg/kg CsA and the ability to reduce steroid therapy. Five females and 1 male were recruited; mean age 66 +/- 8

Three patients are affected by Psoriasic Arthritis, 1 by Rheumatoid Arthritis, 1 by Sjogren Syndrome, and 1 by Myasthenia Gravis. None of them had chronic active hepatitis. HCV genotypes were type 2 (in 3 cases) and type 1 (in 3 cases). Patients were treated with 3 mg/kg of CsA for a period of time ranging from 6 to 12 months. The starting mean dose of prednisone was 12.5 mg/day. Liver function tests were checked monthly and serum HCV-RNA load was checked by RT-PCR before and 2 months into the therapy. The prednisone dose was reduced from 12.5 mg/day to 7.5 mg/day. The aminotransferases levels were unchanged after 6 months. In patients with low HCV-RNA levels before treatment, no modifications of viral load were observed, whereas patients with increased levels at onset showed mild reduction 2 months into the treatment. Immunosuppressive treatment of ADs patients with HCV infection can be safely provided with the integration of CsA.
