Megjegyzések:	Circulating IgG antibodies to oxidized low-density lipoprotein (anti-oxLDL) have been implicated in the development of atherosclerotic plaques. In this study, we investigated the prognostic value of IgG anti-oxLDL antibodies in patients with acute coronary syndrome (ACS). Methods. In total 54 patients with ACS and 41 matched healthy controls were involved in this prospective study. Serum IgG anti-oxLDL levels were assessed by ELISA. Results. Higher IgG anti-oxLDL levels were found in patients with ACS versus controls (22.8 ± 23.3 vs. 7.5 ± 5.27 EU/ml, p < 0.0001). IgG anti-oxLDL concentrations were significantly higher in ACS patients with unstable clinical complications (circulatory insufficiency, malignant arrhythmias, recurring ischaemic pain, positive stress-test, need for urgent coronary intervention or sudden cardiac death) versus those without such complications (30.0 vs. 11.7 EU/ml, p < 0.001). Twelve patients (22%) were taking statins. Patients on statins had a significant reduction in clinical complications (33%) versus patients not receiving statin therapy (61%). IgG anti-oxLDL levels were also different in these two groups (11.4 vs. 25.8 EU/ml, respectively; p = 0.03). Serum IgG anti-oxLDL levels correlated with the subsequent development of unstable coronary events. Levels of anti-oxLDL significantly decreased in response to statin therapy, independently of its lipid-lowering effect. Conclusions. Anti-oxLDL antibodies are involved in ACS. The association of anti-oxLDL with unstable clinical complications may indicate the role of this antibody in plaque destabilization.

Cím:	A comparative study of arterial stiffness, flow-mediated vasodilation of the brachial artery, and the thickness of the carotid artery intima-media in patients with systemic autoimmune diseases / Soltesz, P., Der, H., Kerekes, G., Szodoray, P., Szucs, G., Danko, K., Shoenfeld, Y., Szegedi, G., Szekanecz, Z.

Megjegyzések:	Patients with autoimmune diseases may have increased vascular risk leading to higher mortality rates. Novel imaging techniques are necessary for the early assessment and management of these patients. In this study, we compared augmentation index (AIx) and pulse wave velocity (PWV), indicators of arterial stiffness, to brachial arterial flow-mediated vasodilation (FMD) and common carotid artery intima-media thickness (ccIMT), standard indicators of endothelial dysfunction and atherosclerosis, respectively. We wished to assess the vascular status of autoimmune patients by using a novel, cheap, and reproducible technique, the arteriograph. Altogether, 101 patients with systemic autoimmune diseases including primary antiphospholipid syndrome, systemic sclerosis, rheumatoid arthritis, and polymyositis, all having various types of vasculopathies, as well as 36 healthy individuals were investigated. Arterial stiffness was assessed by a TensioClinic arteriograph, a recently validated technique. Brachial arterial FMD and ccIMT were determined using high-resolution ultrasonography. Autoimmune patients exerted impaired FMD (3.7 +/- 3.8%), increased ccIMT (0.7 +/- 0.2 mm), AIx (1.2 +/- 32.2%), and PWV (9.7 +/- 2.4 m/s) in comparison to control subjects (FMD = 8.4 +/- 4.0%; ccIMT = 0.6 +/- 0.1 mm; Aix = -41.1 +/- 22.5%; PWV = 8.0 +/- 1.5 m/s; p < 0.05). We found a significant negative correlation of FMD with AIx (R = -0.64; p < 0.0001) and PWV (R = -0.37; p = 0.00014). There were significant positive correlations between ccIMT and AIx (R = 0.34; p = 0.0009), ccIMT and PWV (R = 0.44; p < 0.0001), as well as AIx and PWV (R = 0.47; p < 0.0001). AIx, PWV, and ccIMT positively correlated and FMD negatively correlated with the age of the autoimmune patients. Arterial stiffness indicated by increased AIx and PWV may be strongly associated with endothelial dysfunction and overt atherosclerosis in patients with autoimmune diseases. Assessment of arterial stiffness, FMD, and ccIMT are reproducible and reliable noninvasive techniques for the complex assessment of vascular abnormalities in patients at high risk.
