[Association between chronic hepatitis C virus infection and cryoglobulinemia]
Hepatitis C virus infection (HCV) causes both acute and chronic liver disease and can be also associated with cryoglobulinemia (SC). SC is a systemic vasculitic disease, typically characterized by lower extremity purpure, arthralgias and fatigue and by circulating immune complexes which precipitate at low temperatures. We examined the prevalence of SC in a prospective study of 84 patients with chronic HCV hepatitis. Cryoglobulinemia was detected in 44 patients (53.4%) and was associated with the severity of liver damage and the duration of the disease. The analysis of HCV genotypes demonstrated a prevalence of 1 b. The amount of cryoglobulinemia was low in all the patients with SC and only 20% showed a clinical syndrome.
