Abstract
Introduction: Systemic lupus erythematosus (SLE) is associated with premature cardiovascular disease (CVD) and mortality, unexplained by traditional risk factors. Impairment of microcirculation and vascular hemodynamics may represent early signs of vascular affection. We hypothesized that studies of microcirculation and pulse waves may provide additional information, compared to ultrasound (US) alone, for the detection of early vascular disease in SLE. Methods: Sixty well-characterized SLE-patients (52 women, eight men; mean age 43.21 ± 1.3 years) characterized by lupus nephritis (LN; n = 20), antiphospholipid syndrome (APS; n = 20) or skin and joint involvement (n = 20) and 60 healthy controls were included. Microcirculatory peak oxygen saturation (OxyP) was evaluated using a novel combined laser Doppler flowmetry/diffuse reflectance spectroscopy method. Pulse waves were recorded in the radial artery by the aid of applanation tonometry in order to calculate central augmentation index (AIx75). Intima-media thickness (IMT) and plaque occurrence were evaluated using high frequency US, in carotid and central arteries. Results: Lower OxyP (84 ± 8 vs. 87 ± 5 %, p = 0.01) and higher AIx75 (17.3 ± 13.9 vs. 10.0 ± 14.2 %, p = 0.005) were seen in the SLE cohort. OxyP was inversely correlated with IMT in internal carotid artery (ICA), (R = -0.32, p = 0.01). AIx75 correlated with IMT in common carotid artery (CCA), (R = 0.36, p = 0.005), common femoral artery (CFA), (R = 0.43, p = 0.001), and ICA (R = 0.27, p = 0.04). AIx75 correlated negatively with OxyP (R = -0.29, p = 0.02). SLE-patients with plaque had lower OxyP values (80 ± 8 vs. 85 ± 7 %, p < 0.001) and higher AIx75 (23.0 ± 11.6 vs. 15.5 ± 14.2 %, p < 0.001) compared to those without plaque. Conclusion: Impaired microcirculation and vessel hemodynamics were observed in SLE. These methods correlated with IMT and plaque occurrence. The importance of early macro- and micro-circulatory vascular affection for increased risk of CVD in SLE will be followed-up in future studies.

Abstract
Objective To evaluate the effect of endovascular therapy (EVT) on the central blood pressure (CBP) and augmentation index (AIx) in patients with peripheral artery disease (PAD). Methods The CBP and AIx were assessed by radial applanation tonometry the day before and the day after EVT. We compared the differences in the therapeutic effects between the stenotic and occlusive lesions and between the iliac and superficial femoral artery (SFA) lesions. Patients We enrolled 60 consecutive patients with PAD who underwent EVT for de novo lesions. Results Both the CBP and AIx were significantly decreased after EVT (125±22 mmHg to 112±22 mmHg; p=0.002 and 84%±16% to 73%±15%; p<0.001, respectively). The effects of EVT on the CBP and AIx were equivalent, regardless of whether the target lesion was the stenotic lesion or the occlusive lesion. There were no significant differences between the iliac and SFA lesions in the effects of EVT on the CBP and AIx. Conclusion EVT improved the CBP and AIx in patients with PAD, regardless of the morphology or site of the lesions.
