Vascular dysfunction and inflammation in psoriatic arthritis (PsA) share the same pathogenetic mechanism wherein the proinflammatory cytokine tumor necrosis factor-ƒ (TNF-ƒ) plays a key role. Treatment with anti-TNF-ƒ agents is effective in inhibiting inflammation in PsA; however, their effect on the wall of large arteries has not been studied. Objective. To evaluate the effect of Adalimumab (ADA) on the arterial wall and blood rheological properties in PsA. Subjects and methods. Eighteen patients with PsA [12 women and 6 men; mean age 43.1±10.2 years; disease activity scores (DAS), 4.78 (4.0; 5.45)] were subcutaneously injected ADA, 40 mg/every two weeks, for 12 weeks. The investigators assessed the vascular wall, by measuring the mean and maximum common carotid intima-media thickness (IMT) by ultrasound duplex scanning, and arterial rigidity (AR), by determining the refraction index (RI,%) and the rigidity index by digital volume photoplethysmography and Doppler study measuring the aortic pulse wave velocity (PWV) in the carotid-femoral segment (Micromedical, UK), before and after treatment. Erythrocyte aggregation (EA) parameters [Т1 (sec), Kt (c.u.); ƒ (sec-1), I2,5 (%)] were measured recording the rate of inverse light scattering and the levels of blood lipids [total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG)], and atherogenicity coefficient (AC) by routine methods on an automated Express plus analyzer (Bayer, Germany) at baseline, 4, and 12 weeks. The median and the interquartile range [Me (Q25; Q75)] were calculated; the changes in the parameters were estimated by the Wilcoxon test (Wt) and the Friedman test (Ft) for dependent samples; p
