Open Access Abstract IL-18 an immunoregulatory and proinflammatory cytokine has been shown to play an important pathogenic role in Th1-driven autoimmune disorders. In this study we evaluated the circulating levels and salivary-gland expression of IL-18 in patients with Sjogren s syndrome SS a mainly Th1-mediated disease. IL-18 serum levels were measured by ELISA in 37 patients with primary SS 42 with rheumatoid arthritis and 21 normal controls. We demonstrated high IL-18 serum levels in SS similar to those in rheumatoid arthritis patients and significantly higher than in controls P . In addition IL-18 serum concentrations were significantly higher in anti-SSA Ro and anti-SSB La than in anti-SSA Ro and anti-SSB La SS patients respectively P P .
