Abstract
OBJECTIVE: Only a small fraction of patients with hepatitis C virus (HCV) positive mixed cryoglobulinemia achieve longterm recovery after interferon (IFN) therapy; we evaluated the effectiveness and safety of combination therapy (interferon plus ribavirin) in nonresponders or those who relapsed after one or more courses of IFN. METHODS: Twenty-seven patients with HCV positive mixed cryoglobulinemia were studied. All were treated with IFN-a2b (3 MU 3 times weekly) for one year, plus daily oral ribavirin 1000 or 1200 mg. RESULTS: Five patients (18.5%) obtained complete recovery from viral infection and from all signs and symptoms of disease. During treatment, most patients (85%) improved clinically. All 5 responders were "relapsers" to the first treatment(s). CONCLUSION: Combination therapy of IFN plus ribavirin could be useful for patients with mixed cryoglobulinemia resistant to IFN as monotherapy.
