ABSTRACT Adhesion molecules play an important role in the development and course of coronary atherosclerosis. In this study, soluble forms of vascular cell adhesion molecule (VCAM-1) intercellular adhesion molecule-1 (ICAM-1), E-selectin and P-selectin were evaluated in patients with various clinical presentations of coronary atherosclerosis and compared them to those with angiographically documented normal coronary arteries. Venous plasma samples were collected from 43 patients with acute myocardial infarction (AMI), 45 with unstable angina pectoris (UAP), 34 with stable angina pectoris (SAP) and 29 subjects with normal coronary arteries (control). The VCAM-1 level was significantly higher in patients with AMI (mean +/- SEM; 799.8 +/- 26.3 ng/ml) than those with UAP (644.2 +/- 26.7 ng/ml) and SAP (526 +/- 32.5 ng/ml) and controls (270 +/- 26.8 ng/ml). In patients with UAP, VCAM-1 was found to be significantly elevated as compared to the SAP group and controls. VCAM-1 level was also higher in SAP group than the controls. Serum levels ICAM-1 were similar among patients with AMI (424.1 +/- 15.2 ng/ml), UAP (403 +/- 12.3 ng/ml) and SAP (381.2 +/- 16.2 ng/ml); however, levels of ICAM-1 was significantly elevated in these groups as compared to the controls (244.3 +/- 11). The mean level of E-selectin was not different in AMI and UAP groups (47.2 +/- 2.2 vs. 42.6 +/- 2.1 ng/ml; respectively). However, it was significantly higher in acute coronary syndrome groups as compared to SAP (33.4 +/- 2.3 ng/ml) and control subjects (30.7 +/- 1.9 ng/ml). Serum levels of E-selectin were similar in SAP group and controls. For P-selectin, no significant difference was observed between AMI and UAP groups (187.5 +/- 7.2 vs. 181.7 +/- 4.7 ng/ml; respectively), however, it was significantly higher in both groups as compared to SAP group (146.1 +/- 7.4 ng/ml) and controls (108 +/- 6.6 ng/ml). Serum level of P-selectin was significantly higher in patients with SAP than the control group. In conclusion, determination of serum VCAM-1, E-selectin and P-selectin levels seems more useful for detecting coronary plaque destabilization.

    • "Adhesion molecules VCAM-1 and ICAM-1 have different expression patterns on endothelial membrane and probably play different roles in atherogenesis [51]. While sVCAM-1 is a predictive marker of increased risk for future coronary events only in patients with the presence of atherosclerosis [52], sICAM-1 is predictive – like hsCRP – also in initially healthy people [53].

    ABSTRACT: OBJECTIVES: Both decreased and increased risk of cardiovascular events/mortality has been reported with high adiponectin levels. Only a few studies have reported an association of adiponectin with markers of haemostasis/endothelial dysfunction which might explain the reported discrepancies. DESIGN AND METHODS: We evaluated the association of total adiponectin with von Willebrand factor (vWF), plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator (t-PA), soluble thrombomodulin (sTM), adhesion molecules sICAM-1 and sVCAM-1, lipids and markers of insulin resistance (IR) in 308 asymptomatic dyslipidemic subjects and healthy controls. Subjects were divided into 4 dyslipidemic phenotypes (DLP): DLP1 (TG<1.5mmol/l+ApoB<1.2g/l), DLP2 (TG≥1.5+ApoB<1.2), DLP3 (TG<1.5+ApoB≥1.2) and DLP4 (TG≥1.5+ApoB≥1.2). The results were evaluated also according to the presence (+) and absence (-) of metabolic syndrome (MS). RESULTS: In hyperlipidemic subjects (DLP 2-4), PAI-1, t-PA and sICAM-1 correlated with markers of IR but only t-PA correlated inversely with adiponectin. In contrast positive association of adiponectin with vWF, sTM and sVCAM-1 was found but none of these parameters correlated with markers of insulin resistance. In multiple regression analysis, adiponectin remained independently associated with vWF [in DLP3, DLP4, DLP2-4, MS(-)], with sTM [in DLP2, DLP4, DLP2-4, MS(+)] and with sVCAM-1 [in DLP2, DLP3, DLP4, DLP2-4, MS(+)]. In healthy controls (DLP1), no association between adiponectin and markers of haemostasis/endothelial dysfunction was found. CONCLUSION: The independent positive association of adiponectin with vWF, sTM and sVCAM-1 deserves further evaluation in connection with the risk of atherothrombotic cardiovascular events.

    • "Since their plasma levels may reflect the activation-induced up-regulation of the cellular forms [8], these soluble molecules are considered potential biomarkers for CVD [9]. In fact, they have been measured in human plasma and several lines of evidence support a crucial role of CAMs in the development of atherosclerosis [3] [6] [10]. The expression of these molecules is very rare in normal coronary artery segments, while they are elevated in patients with atherosclerotic lesions and dyslipemia [2] [8]. "

    ABSTRACT: Serum levels of soluble cellular adhesion molecules (CAMs) and blood lipid parameters have been used as markers of inflammatory processes associated with cardiovascular disease (CVD) events. The present study evaluated the effects of the intake of n-3 polyunsaturated fatty acids (PUFAs) in fish and fish oil within energy-restricted diets, on soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular adhesion molecule-1 (sVCAM-1). Two hundred and seventy-five healthy European subjects aged between 20 and 40 years, were randomized to one of four hypocaloric dietary groups: control (sunflower oil capsules, no seafood), lean fish (3 x 150 g portions of cod/week), fatty fish (3 x 150 g portions of salmon/week), fish oil ((docosahexaenoic acid (DHA)+eicosapentaenoic acid (EPA) capsules, no seafood)). Diets rich in lean fish significantly decreased ICAM-1 levels, around 5% from baseline to endpoint (p<0.05), and had no effect on VCAM-1 levels. No significant differences were observed in sICAM-1 levels after the intervention with fatty fish or fish oils. On the other hand, these two seafood based diets were responsible for a significant increase of VCAM-1 levels [fatty fish; 16.1% and fish oil; 21.9%] respectively (p<0.05). CAMs as inflammatory biomarkers in young and healthy subjects are not conclusive for the evaluation of CVD risk. Hypocaloric fish diets had a different effect on CAMs, being lean fish responsible for the highest decrease in ICAM-1. On the other hand, VCAM-1 results allow speculation that a low dose of n-3 PUFA may be anti-inflammatory contrarily to a high dose which can have a pro-inflammatory effect. CAMs mechanism is complex and affected by multiple factors such as lifestyle, gender, and n-3 dose and source.
