Summary Background Psoriasin (S100A7) and koebnerisin (S100A15) are proinflammatory proteins upregulated in psoriasis, but their relation to atherosclerosis remains unclear. Aim To evaluate the role of serum psoriasin and koebnerisin as possible markers for subclinical atherosclerosis in patients with psoriasis. Methods Serum levels of psoriasin and koebnerisin were measured by ELISA in 45 patients with psoriasis and in 45 healthy controls ( HC s). Intima–media thickness ( IMT ) of the right and left common carotid arteries was measured to detect the presence of subclinical atherosclerosis. Clinical severity of psoriasis was estimated using the Psoriasis Area and Severity Index ( PASI ). Results Compared with HC s, patients with psoriasis had significantly higher levels of psoriasin (26.61 ± 22.45 ng/ mL vs. 6.31 ± 1.68 ng/ mL , P < 0.001) and koebnerisin (21.2 ± 13.12 ng/ mL vs. 12.2 ± 4.67 ng/ mL , P = 0.001), and significantly higher IMT values (1.07 ± 0.4 mm vs. 0.61 ± 0.1 mm, P < 0.001). A positive correlation was observed between IMT and PASI ( r = 0.78, P < 0.001), serum psoriasin ( r = 0.48, P > 0.01) and serum koebnerisin ( r = 0.48, P < 0.01). Patients with psoriasis with subclinical atherosclerosis had higher serum levels of koebnerisin compared with patients without subclinical atherosclerosis ( P = 0.04), which was not observed for psoriasin ( P = 0.94). Conclusion Serum psoriasin and koebnerisin correlate with IMT , underlining their value as a potential link between psoriasis and atherosclerosis. In particular, koebnerisin seems to be a useful marker of subclinical atherosclerosis in patients with psoriasis.
