Abstrakt:	Introduction: Blood pressure (BP) variability (BPV) has emerged as an indicator of subclinical organ damage and an independent predictor of cardiovascular disease (CVD) morbidity and mortality in high-risk populations. Aim: We aimed to assess short-term variability of both brachial and aortic BP in psoriasis, a common immune-mediated inflammatory disorder characterized by increased CVD risk. Methods: Psoriasis patients and non-psoriasis individuals had their BP assessed throughout a 24 h period (Mobil-O-Graph device). Brachial and aortic BPV during the 24 h and the respective daytime and nighttime periods was calculated from relevant ambulatory BP profiles. In-house software was applied to automatically calculate average real variability (ARV) of brachial and aortic systolic (bSBP, aSBP) and diastolic BP (bDPB, aDBP), and the weighted standard deviation (wSD) of 24 h bSBP/aSBP. 24 h pulse wave velocity (PWV) and augmentation index (AIx) were used as widely applied markers of arterial stiffness. Results: Psoriasis patients (n = 74) presented increased ARV of 24 h and daytime bSBP/aSBP, and increased ARV of 24 h and daytime bDBP/aDBP, compared to controls (n = 40). PWV and AIx correlated with ARV of 24 h bSBP/aSBP, daytime bSBP/aSBP, while PWV further correlated with ARV of nighttime aSBP. The observed associations with PWV, yet not AIx, with indices of BPV remained significant after adjusting for CVD risk factors. Conclusions: This is the first study reporting increased 24 h variability of both brachial and aortic BP in psoriasis. The association of short-term BPV with arterial stiffness implies a potential role of BPV in terms of CVD risk stratification in patients with chronic immune-mediated inflammation.
