OBJECTIVE:No single previous study has evaluated serum levels of the proinflammatory cytokines interleukin-1beta (IL-1beta), IL-6, and tumor necrosis factor alpha (TNFalpha) in patients with hepatitis C virus-associated mixed cryoglobulinemia (HCV-MC). This study was undertaken to evaluate serum levels of these cytokines in patients with HCV-MC. METHODS:Serum IL-1beta, IL-6, and TNFalpha were assayed in 43 patients with HCV-MC, in 43 sex- and age-matched patients with chronic HCV without cryoglobulinemia, and in 43 sex- and age-matched controls. RESULTS:HCV-MC patients showed significantly higher mean IL-1beta, IL-6, and TNFalpha levels than did the controls (P<0.01) or the HCV patients (P<or=0.04). Serum levels of IL-6 and TNFalpha were significantly higher in HCV patients than in controls (P<0.05). CONCLUSION:Our findings demonstrate elevated serum levels of IL-1beta, IL-6, and TNFalpha in patients with HCV-MC. If the importance of IL-1beta and IL-6 in the pathogenesis of MC is confirmed, these results will open the way for the evaluation of new therapies for MC.
