Background: There is a great body of evidence indicating that some inflammatory skin diseases, such as psoriasis, are mediated by oxidative stress. Trace metals have been shown to be involved in oxidative stress response. Altered trace metal homeostasis in psoriasis has been studied. However, limited number of studies has focused on the involvement of metal binding proteins in psoriasis. Materials and Methods: In a case control-study, serum levels of Iron (Fe), Copper (Cu), Transferrin (Trf), and Ceruloplasmin (Cp) were measured in 40 psoriasis patients and matched healthy controls. The severity of the disease was measured using psoriasis area and severity index (PASI), and the association of severity based on PASI score and measured elements and proteins was investigated. Results: Forty patients with psoriasis (mild: 14 and moderate to severe: 26) and 40 healthy controls were included in this study. The serum Fe, Trf, and Cu/Cp levels of the patients with psoriasis were statistically lower compared with those of the controls; serum levels of Cp was elevated in patients with psoriasis compared to controls (P = 0.02). No significant difference was observed between the two groups regarding serum levels of Cu (P = 0.07). Conclusion: Cu/Cp ratio of the patients with psoriasis was statistically lower compared with those of the controls.
