[Mixed cryoglobulins and autoimmunity in hepatitis C].

We explored and studied cryoglobulins and autoantibodies in 149 patients with hepatitis C. 49% of untreated patients have cryoglobuliemia (36% polyclonal cryoglobulins) and 76% of ineffectively treated patients since more than 6 months (50% polyclonal cryoglobulins). Other observed cryoglobulins are half of type II and half oligoclonal.
