Özet

Angiogenesis is an important process being involved in the pathogenesis of psoriasis and promises new potential parameter for diagnosis and screening of treatment. This study investigated the levels of signal peptide-CUB-EGF (epidermal growth factor-like protein) family domain-containing protein (SCUBE) 1 and 3. Potential value as a novel marker of angiogenesis in patients with psoriasis is also evaluated by assessing possible relation of SCUBE-1 and 3 with disease activity in conjunction with vascular endothelial growth factor (VEGF) levels, as an established marker of angiogenesis. Forty-eight patients with psoriasis (aged > 18 years) and 48 age- and gender-matched healthy controls were included. Detailed information was obtained through history and physical examination. Psoriasis area and severity index (PASI) scores were calculated. Blood SCUBE 1 and 3, and VEGF levels were measured by enzyme-linked immunosorbent assay. The mean PASI score of the patients was 6.7 +/- 4.1. Patients' serum SCUBE 1 and 3 and VEGF levels were significantly higher than those of the controls (P = 0.001). The sensitivity and specificity were calculated as 83 and 62% for the 0.67 ng/ml cut-off level of SCUBE 1, and 63 and 71% for the 2.57 ng/ml cut-off level of SCUBE 3, respectively. A cut-off VEGF level of 310 ng/mL predicted the presence of psoriasis with a sensitivity of 50% and specificity of 77%. The results of this pioneering study indicate that SCUBE protein family appears to have a probable role in the pathogenesis and angiogenesis development in psoriasis and SCUBE 1 and 3 may be novel markers of angiogenesis in psoriasis.
