C-reactive protein and markers for thrombophilia in patients with chronic plaque psoriasis.
Chronic plaque psoriasis is associated to an increased risk of cardiovascular events. The aim of our study is to test patients with psoriasis for common markers of acquired and inherited thrombophilia. A cross-sectional study on 172 patients with psoriasis and 198 controls was carried out. The plasma levels of coagulation protein C, coagulation protein S, homocysteine, folic acid, C-reactive protein (CRP) and fibrinogen as well as activated protein C resistance and antithrombin III activity, were measured. CRP and homocysteine levels were higher in patients with psoriasis than in controls (5.9 ± 7.1 vs 3.1 ± 2.4 mg/L, p=0.0003 and 16.3 ± 12.8 vs 10.4 ± 4.6 umol/L, p=0.0001; mean ± SD) whereas folic acid was lower in psoriatic patients compared to controls (4.3 ± 7.2 vs 12.6 ± 7.9 p=0.006). Levels of coagulation protein C, coagulation protein S, fibrinogen as well as activated protein C resistance, antithrombin III activity were within normal ranges both in cases and controls. In a multivariate regression analysis, psoriasis severity was an independent predictor of higher CRP. In conclusion, high levels of serum CRP and homocysteine were found in patients with psoriasis, related to the severity of the disease. These data suggest that the increased risk of thrombotic cardiovascular events observed in psoriasis patients should be ascribed to an acquired rather than inherited thrombophilic status.
