OBJECTIVE:No data are available about circulating levels of the CXCL11 chemokine in hepatitis C virus (HCV)-associated mixed cryoglobulinemia (MC) patients with or without autoimmune thyroiditis (AT). The aim of the present study, therefore, was to evaluate serum CXCL11 levels in these patients.DESIGN:Serum CXCL11 (and for comparison, CXCL10) was measured in 45 patients with MC, 45 patients with MC and AT (MC + AT), 45 sex- and age-matched controls without AT (control 1), 45 sex- and age-matched patients with AT without cryoglobulinemia (control 2), and in 45 sex- and age-matched patients with hepatitis C chronic infection without MC (HCV+).RESULTS:Serum CXCL11 and CXCL10 levels were significantly higher in control 2 than in control 1 (p < 0.01). MC patients had CXCL11 and CXCL10 significantly higher than control 1 (p < 0.01). MC + AT patients had CXCL11 and CXCL10 higher than control 2 (p < 0.01) and MC patients (p = 0.02). Serum CXCL11 levels were not associated with any of the clinical features of cryoglobulinemia in patients with MC and MC + AT, which was the same for CXCL10. CXCL10 and CXCL11 in HCV+ patients were significantly higher than in controls 1 and 2, but lower than in MC or MC+AT patients.CONCLUSION:Our study first demonstrates higher serum levels of CXCL11 chemokine in patients with MC than in HCV+ patients, and in particular in the presence of AT.

The aim of the present study, therefore, was to evaluate serum CXCL11 levels in these patients.DESIGN:Serum CXCL11 (and for comparison, CXCL10) was measured in 45 patients with MC, 45 patients with MC and AT (MC + AT), 45 sex- and age-matched controls without AT (control 1), 45 sex- and age-matched patients with AT without cryoglobulinemia (control 2), and in 45 sex- and age-matched patients with hepatitis C chronic infection without MC (HCV+).RESULTS:Serum CXCL11 and CXCL10 levels were significantly higher in control 2 than in control 1 (p < 0.01). MC patients had CXCL11 and CXCL10 significantly higher than control 1 (p < 0.01). MC + AT patients had CXCL11 and CXCL10 higher than control 2 (p < 0.01) and MC patients (p = 0.02). Serum CXCL11 levels were not associated with any of the clinical features of cryoglobulinemia in patients with MC and MC + AT, which was the same for CXCL10.
