Abstract
We studied the impact of hypertension along with traditional and new cardiovascular risk factors on the structural and functional properties of arteries in psoriatic arthritis (PsA) patients. We examined 42 PsA subjects (aged 51±9 years) stratified according to hypertensive status (19 normotensive, PsA-NT and 23 hypertensives, PsA-HT). Thirty-eight normotensive subjects (C-NT) and 23 hypertensives (C-HT) comparable by age and sex served as controls. Mean carotid intima-media thickness (mean-IMT) and mean of the maximum IMT (M-Max) were evaluated by ultrasound in carotid artery segment bilaterally. Post-occlusion flow-mediated dilation (FMD) of the brachial artery was evaluated by ultrasonography. These parameters were correlated with risk factors, markers of inflammation and disease activity. Values of mean-IMT were higher in both groups of PsA patients compared with C-NT (0.68 mm in PsA-NT and 0.75 mm in PsA-HT versus 0.61 mm in C-NT). PsA-HT displayed higher M-Max (0.95 mm) versus both C-HT (0.71 mm) and PsA-NT (0.79 mm). FMD was impaired in PsA subjects compared with C-NT (5.7% in PsA-NT and 6.0% PsA-HT versus 9.3% in C-NT), whereas there was no difference among PsA-HT, PsA-NT, and C-HT groups. Values of carotid IMT were directly related to tumor necrosis factor (TNF)-α, osteoprotegerin (OPG), blood pressure and lipid profile levels. FMD showed an inverse relationship with TNF-α and blood pressure, but no correlation with lipids. In conclusion, PsA per se implies a pro-atherogenic remodeling, which is enhanced by the hypertensive status. TNF-α and OPG may have an independent role in the development of such vascular damage.Entities:
