Objective: to evaluate the effect of golimumab (GLM) on the receptor activator of NF-κB ligand (RANKL)/osteoprotegerin (OPG) transmembrane molecular system and arterial stiffness in patients with rheumatoid arthritis (RA).Subjects and methods. Thirty-six patients with RA were examined and randomized into 2 groups based on disease duration (less than or more than 2 years). The serum levels of OPG, and RANKL, were investigated. Dual-energy X-ray absorptiometry and pulse wave contour analysis were performed before and 52 weeks after GLM treatment.Results and discussion. Group 1 patients demonstrated increased serum OPG levels that were on average 3.6 times higher than in the controls (р=0.005) and 2.1 times higher than in Group 2 (р=0.01). In Group 2 patients, the RANKL concentration was 9-fold higher than that in the controls (p=0.001) and 30.6% higher than in Group 1 (p=0.01). The examinees were found to be diagnosed with subclinical damage to the great arteries (increases in augmentation index (AIp), stiffness index (SI), and reflection (RI) index), which progressed with a longer RA duration. After GLM treatment, serum OPG and RANKL levels decreased in Group 1 patients by 2.1- (p<0.001) and 1.7-fold (p<0.01), respectively. In Group 2, the level of RANKL dropped by 32.2% (p<0.01), without significant OPG concentration changes. After GLM treatment, the pulse wave contour analysis parameters in Group 1 did not differ from those in the controls; Group 2 showed significant decreases in AIp by an average of 1.8 times (p<0.01), in SI by 1.2 times (p<0.01), and in RI by 1.6 times (p<0.01).Conclusion. GLM treatment in RA patients is accompanied by a lower imbalance in the RANKL/OPG transmembrane molecular system and exerts a vasoprotective effect on the large elastic vessels (reductions in AIp and SI) and small muscular arteries (a decrease in RI).

Background Measurements of aortic stiffness [aortic pulse wave velocity (PWV) and augmentation index (AIx)] have been established as powerful predictors of survival on hemodialysis (HD). Abnormal endothelial-dependent and endothelial-independent vascular reactivity and increased arterial stiffness are commonly described in HD patients. There is, however, a lack of information on the comparative impact of different renal replacement therapies (RRTs) on PWV and AIx, and how these different methods might influence endothelial-dependent abnormal vasodilatation. Objective To describe in a cross-sectional design arterial compliance and distensibility in continuous ambulatory peritoneal dialysis (CAPD) versus HD versus renal transplant (RTx) patients, compared with age- and blood pressure-matched essential hypertensive controls. The PWV and aortic AIx were determined from contour analysis of arterial waveforms recorded by applanation tonometry in 40 CAPD, 41 HD, 20 RTx patients (with normal serum creatinine), and 20 controls with essential hypertension (all normotensive under treatment). Endothelial-dependent and endothelial-independent vascular reactivities were assessed by changes in AIx following challenges with inhaled salbutamol and sublingual nitroglycerin respectively. Results CAPD patients had significantly stiffer arteries than all other categories. The PWV was 8.29 ± 1.09 m/second in CAPD patients, significantly higher ( p < 0.05) compared to HD subjects (7.19 ± 1.87 m/s). Both dialysis subgroups had significantly higher PWV values compared to RTx patients (6.59 ± 1.62 m/s) and essential hypertensive controls (6.34 ± 1.32 m/s), p < 0.05. The AIx had a profile similar to PWV in different RRTs. All groups with the exception of CAPD subjects had a significant decrease in AIx following salbutamol. Moreover, the vasodilatation induced by either nitroglycerin or salbutamol was significantly blunted compared to HD. Overall, both dialysis categories had more abnormal responses compared to RTx patients and essential hypertensive controls. Conclusion CAPD is associated with stiffer arteries and more profoundly abnormal endothelial-dependent vasomotor function, compared to matched HD subjects. These differences in arterial physical properties might explain differences seen in cardiac structure and function between the RRTs.

Abstract Background/Introduction Arterial stiffness and aortic hemodynamics are independent predictors of adverse cardiovascular events. Indications for transcatheter aortic valve implantation (TAVI) are expanding and aortic valve calcifications (AVC) are an important prognostic factor of the success of TAVI. Purpose We sought to investigate the associations between AVC and aortic vascular function/hemodynamics. Methods Fifty-two high-risk patients (mean age 80.4±8.5 years, 27 male) with severe symptomatic aortic stenosis undergoing TAVI were included. Arterial stiffness was estimated through carotid-femoral pulse wave velocity (cfPWV) and brachial-ankle pulse wave velocity (baPWV). Aortic hemodynamics (aortic pressures, aortic augmentation index corrected for heart rate [AIx@75]) were also measured. Measurements were conducted prior to the implantation and at discharge. In all patients, a native and contrast-enhanced multislice cardiac computed tomography were performed pre-interventionally. AVC were then graded semi-quantitatively as follows: grade 1 – no calcification; grade 2 – mildly calcified (small isolated spots); grade 3 – moderately calcified (multiple larger spots); grade 4 – severely calcified (extensive calcification of all cusps). Results Group 1 (subjects with none/mild AVC, n=29) did not significantly differ in age, gender and body-mass index compared to group 2 (subjects with moderate/severe AVC, n=23). As far as the traditional cardiovascular risk factors were concerned, only hypertension (p=0.008), coronary artery disease (p=0.016), atrial fibrillation (p=0.075) and insulin-dependent diabetes mellitus (p=0.068) were found to be more prevalent in group 2. Group 2 had significantly higher both cfPWV and baPWV (8.3±1.7 vs 7.2±1.2 m/s and 1750±484 cm/s vs. 2101±590 cm/s with p=0.008 and p=0.022 respectively) compared to Group 1 (Figure 1). Even after adjustment for age, gender and systolic blood pressure, aortic stiffness indices were higher in Group 2 compared to Group 1 (p=0.038 and p=0.048, respectively). There was no statistically significant difference in peripheral or aortic pressures as well as in wave reflections indices between the two groups. Conclusion Our study shows that in patients with aortic valve stenosis there is a correlation between increased aortic stiffness and a greater extent of damage of aortic valvular leaflets as well as calcifications.

Aim. To investigate the parameters of pulse wave contour analysis (PWCA) and microcirculation (MC) in patients with arterial hypertension (AH), dyslipidemia (DLP), and high cardiovascular risk levels (SCORE >5%); to compare the dynamics of these parameters during the treatment with rosuvastatin or atorvastatin. Material and methods. The study included 82 patients (mean age 53±10 years) with the high-risk AH (SCORE levels >5%), DLP, and no strict contraindications to statins. All patients were randomised into two comparable groups: Group I (n=40; mean age 51±10 years), receiving atorvastatin and standard AH treatment; and Group II (n=42; mean age 52±10 years), receiving rosuvastatin and standard AH treatment. At baseline and after 5 weeks, all patients underwent the MC assessment (conjunctival biomicroscopy) and PWCA (AngioScan-01). The following parameters were assessed: stiffness index (SI), reflection index (RI), augmentation index (AIx), and increased pulse wave amplitude (PWA). Results. In the atorvastatin group, mean SI values were 5,87±2,05 m/s, RI values 35,64±19,98%, mean AIx values for heart rate of 75 beats per minute (AIx75) 41,21±14,56%, and mean central blood pressure (BP, Spa) levels 144,35±22,31 mm Hg. In the rosuvastatin group, the respective values were 5,01±2,56 m/s (SI), 37,01±14,56% (RI), 41,23±14,35% (AIx75), and 148,98±7,89 mm Hg (BP, Spa). All participants demonstrated PW Types A and B, as a marker of increased arterial stiffness, and positive AIx and AIx75 values. The treatment with atorvastatin and rosuvastatin was associated with a significant reduction in ∆SI (-0,87 and -0,89 m/s, respectively). Both groups demonstrated a non-significant reduction in ∆RI (-7,89 and -7,21%, respectively) and ∆AIx (-1,88 and -1,92%, respectively). PWA increased by 1,82±0,62 times in the atorvastatin group and by 1,95±0,81 times in the rosuvastatin group. At baseline, both groups demonstrated disturbed conjunctival MC (arterio-venular coefficient 1:3, stasis, and Stage III erythrocyte aggregation). Atorvastatin and rosuvastatin treatment was linked to a regression in the last two parameters, which could be explained by the improved vascular wall elasticity. Conclusion. In high-risk patients with AH, the PWCA data suggested an increase in arterial stiffness, which was combined with conjunctival MC disturbances. Statin therapy improved not only blood lipid levels, but also MC, vascular stiffness, and endothelial function parameters, which was more pronounced in the rosuvastatin group.

Aim: to study parameters of arterial stiffness and subclinical atherosclerosis in patients with axial spondyloarthritis (axSpA) without clinically manifest cardiovascular pathology depending on the presence of anemia.Material and methods. 102 patients with axSpA (mean age – 37.7±9.8 years, axSpA duration – 13.5±8.7 years, 66 (64.7%) men) were included. The BASDAI index and C-reactive protein (CRP)-based ASDAS score were measured, the hemogram, the erythrocyte sedimentation rate (ESR), and the level of CRP were studied. Parameters of arterial stiffness were studied by oscillography and photoplethysmography, intima-media thickness (IMT) was evaluated by B-mode ultrasound according to standard protocols.Results. During analysis of pulse wave properties, no statistically significant differences in parameters of vascular wall stiffness were found in axSpA patients with and without anemia. Aortic pulse wave velocity (PWVao) in patients with anemia was 7.4±1.5 m/sec, aortic augmentation index (Aix-ao) was 19.1±13.7%, stiffness index (SI) was 8.2±1.7 m/sec; in patients without anemia – 7.4±1.4 m/sec, 17.3±10.6% and 8.8±2.0 m/sec, respectively (p >0.05 for all). IMT in patients with anemia was 0.70±0.13 cm, in patients without anemia – 0.73±0.16 cm (p >0.05). Correlation analysis was performed and significant correlations were noted between Aix-ao, PWVao, SI, IMT and age (r=0.488, r=0.516, r=0.289, r=0.461, respectively, p <0.05); Aix-ao, PWVao and the BASDAI index (r=0.243, r=0.253, respectively, p <0.05). Significant correlations between PWVao and Aix-ao (r=0.442, p <0.001), SI (r=0.273, p=0.011) and IMT (r=0.236, p=0.034) were found.Conclusion. The present study did not confirm the negative effect of anemia on vascular wall stiffness parameters and IMT in patients with axSpA. We consider that potential protective effect of anemia, due to well-known pathophysiological patterns — a decrease in blood viscosity and the induction of nitric oxide synthesis, plays an important role. Further studies are required to assess relationship between hemoglobin levels and markers of endothelial dysfunction in patients with axSpA.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Globally, stroke is the second leading cause of death, leading to a reduction in life expectancy and disability of patients. It seems important to study and introduce into practical health care both new approaches to stroke prevention and measures aimed at full recovery in the post-stroke period. Purpose To assess the antihypertensive therapy (AHT) in patients with arterial hypertension (AH) in the early post-stroke period of ischemic stroke (IS), based on indicators of arterial stiffness. Methods The study included 180 patients with hypertension (mean age 64 years) in the acute period of ischemic stroke (IS). Inclusion criteria in this trial: AH, age over 40 years, time from the onset of stroke no more than 48 hours. Arterial stiffness was assessed by an oscillometric method with an assessment of the 24-hour reflected wave transit time (RWTT), aortic augmentation index (AIxao)), arterial stiffness index (ASI), and pulse wave velocity (PWV). The indicators were assessed at the time of admission, at the time of discharge from the hospital (14-21 days) and 2 months after discharge. We determined endothelin-1 (ET-1) levels by ELISA at admission and 2 months after discharge. Retrospectively, patients were divided into 5 groups depending on the prescribed AHT: group 1 (48 patients) - ACEIs/ARBs, thiazide-like diuretics (TLDs), group 2 (46 people) - ACEIs/ARBs, nondihydropyridine calcium antagonists (ACs) and beta-blockers (BBs), group 3 (39 people) - ACEIs/ARBs and ACs, group 4 (26 patients) - ACEIs/ARBs and BBs, group 5 (21 people) - ACEIs/ARBs, TLDs and BBs. Results AHT showed a positive trend in terms of arterial stiffness in all 5 groups. Compared with the baseline values, the significant decrease in PWV (12.4 ± 1.7m/s vs 10.9 ± 1.8m/s, p &lt; 0.01), AIxao (39.8 ± 6.3% vs 36.8 ± 5,2%, p &lt; 0.001), ASI (167.9(127.0;174.5) vs 158.8(115.0;168.7)), p &lt; 0.05), increased RWTT (98.0 ± 9.8ms vs 105.3 ± 7.5ms) in group 2 of patients were found. After 2 months, when comparing indicators between groups the significant decrease in PWV to 9.1(8.7; 11.6)m/s, p &lt; 0.01), AIxao to 31.7(29.8;41.9)%, p &lt; 0.01, an increase in RWTT to 107.7(102.4; 110.2)ms, p &lt; 0.01 in the group of patients taking ACEIs/ARBs, ACs and BBs were detected. After 2 months after discharge, a significant decrease of ET-1 was also observed in group 2 (5.8 ± 2.2ng/ml vs 4.2 ± 1.8ng/ml). The combination of ACEs/ARBs and BBs showed the least effectiveness in reducing arterial stiffness. Conclusions The combination of ACEIs/ARBs, ACs and BBs showed the greatest efficiency in reducing the stiffness in patients with hypertension in the early post-stroke period of IS. It seems important for the functional recovery of patients in the post-stroke period to use the drug therapy aimed not only at lowering blood pressure, but also favorably affecting the arterial stiffness.

Objective To explore the association between arterial system augmentation index(AI) and brachial-ankle pulse wave velocity (baPWV). Methods All subjects were selected from a local community. The study included 1752 people living in Shijingshan district, Beijing during April to June,2010. Subjects whose age ranged from 23 to 90 years old [(59.82±11.88) years old] were included and 56.7% of the subjects were women. Pulse wave at the left radial artery was measured and the AI was calculated by Colin pulse wave detection device HEM9000AI. baPWV and ankle-brachial index (ABI) were measured using Colin noninvasive arteriosclerosis tester VP-1000. Color doppler flow imaging was used to measure intima-media thickness (IMT) of the bilateral carotid artery. Results The baPWV was significantly higher in ABI0.9 group and IMT0.9 mm group, while there was no significant difference of AI75 between groups. AI had a low correlation with baPWV (r = -0.068, P = 0.005). Partial correlation analysis showed that there was no significant association between AI and baPWV (r = -0.033, P = 0.17). In multiple stepwise regression analysis, the factors of AI included gender, age, BMI, waist-to-hip ratio, heart rate, ABI and systolic pressure. Conclusion No significant correlation can be found between AI and baPWV. Various factors may influence the measurement of AI. This study suggests that AI may not be a sensitive and reliable index for the evaluation of arterial stiffness.
