Abstract The pathogenesis of systemic sclerosis SSc is characterized by autoimmunity vasculopathy and fibrosis. IL-15 is a pleiotropic cytokine that has impact on immune vascular and connective tissue cells. We therefore investigated IL-15 in the circulation of patients with early SSc and explored possible associations of serum IL-15 with vasculopathy and fibrosis. Serum levels of IL-15 were analysed in 63 consecutive patients with SSc of disease duration less than 4 years and without diseasemodifying treatment. Thirty-three age-matched healthy control individuals were enrolled. Serum IL-15 levels were increased in the sera of SSc patients compared with that of healthy control individuals P . Serum IL-15 levels correlated with impaired lung function assessed both by the vital capacity P and by the carbon monoxide diffusion capacity P . The association between IL-15 and the vital capacity remained after multiple linear regression analysis. Patients with intermediate serum IL-15 levels had a higher .
