Clinical trials of postmenopausal hormone therapy (PHT) have found an early increase in cardiovascular events, and have not demonstrated the reduction in coronary heart disease (CHD) predicted from changes in conventional risk factors or found in observational studies, suggesting that PHT may increase coronary risk through other pathways. We compared baseline levels of C-reactive protein (CRP), interleukin-6 (IL-6), sICAM-1, tissue plasminogen activator antigen (tPA-antigen), D-dimer, homocysteine, triglycerides, total-, HDL- and LDL- cholesterol in 304 cases with incident CHD and 304 controls, according to self-reported use of PHT. Subjects were selected from the 75,343 participants in the WHI Observational Study without baseline cardiovascular disease or cancer. PHT was associated with higher CRP, HDL and triglycerides, and lower tPA-antigen and homocysteine. CRP was highest in users of unopposed conjugated equine estrogen. Levels of IL-6,sICAM-1,D-dimer and total cholesterol did not differ between PHT users and non-users. Transdermal estrogen users had low levels of D-dimer and CRP. Among users of estrogen plus progestin (EP), CRP, IL-6, tPA-antigen, D-dimer, total cholesterol and triglycerides were higher in women with incident coronary events than controls. Estrogen alone (E) controls shared only the tPA-antigen association, but had higher HDL and lower LDL than E cases. In non-users CRP, tPA-antigen and D-dimer were associated with incident CHD. In summary, risk markers differed by PHT category. Some associations differed between women with and without incident CHD, especially for EP, where inflammatory and thrombotic markers were higher in cases. These associations remain speculative pending confirmation in randomized trials.

The interplay between inflammatory and hemostatic mechanisms may play a crucial role in the development and progression of atherosclerosis. The authors evaluated the separate and joint associations of hemostatic and inflammatory variables on peripheral atherosclerotic progression in the Edinburgh Artery Study, a population cohort study of 1,592 men and women aged 55-74 years that started in 1987. Levels of fibrinogen, fibrin D-dimer, von Willebrand factor, tissue plasminogen activator antigen, factor VII, prothrombin fragment 1 + 2, urinary fibrinopeptide A, C-reactive protein, and interleukin-6 were measured at baseline. Arm and ankle blood pressures were measured, and atherosclerotic progression was assessed by computing ankle brachial index (ABI) at baseline (1,582 participants) and after 12 years of follow-up (813 participants). Fibrinogen (p = 0.05) and D-dimer (p < or = 0.05) were significantly associated with ABI change independently of baseline ABI and cardiovascular disease risk factors. However, these associations were no longer significant when analyses were adjusted for either C-reactive protein or interleukin-6. Moreover, subjects with higher levels of both D-dimer and interleukin-6 at baseline had the greatest ABI decline. In conclusion, fibrinogen and D-dimer, but not other hemostatic factors, were associated with progressive peripheral atherosclerosis. Since D-dimer and fibrinogen are acute phase reactants, these data support the hypothesis that inflammation is more related to atherosclerosis than is hypercoagulation.

Lipodystrophy (LD) with varying degrees of lipohypertrophy, lipoatrophy, hyperlipidemia, and insulin resistance is one of the complications of highly active antiretroviral therapy (HAART) and occurs in one to 33 % of HAART-treated, HIV infected children. We summarize the data on the role of leptin, adiponectin, the growth hormone axis, glucocorticoids, sterol response element binding protein 1c (SREBP-1c), the tumor necrosis factor alpha axis (TNF-alpha), interleukin-6 (IL-6), interleukin- 18 (IL-18), interferon-alpha (IFN-alpha), tissue plasminogen activator (tPA), and plasminogen activator inhibitor (PAI-1) in the pathophysiology of LD. Adiponectin levels are generally decreased in LD, whereas leptin levels are increased. Systemic cortisol levels are not elevated in LD, even though glucocorticoids seem to play an important role in LD and the phenotype can be reminiscent of Cushing syndrome. GH resistance in LD needs to be better characterized. While some cytokines show promise as markers for LD, it is difficult to tell whether their derangement is a cause of or the effect of LD.

Haemostatic and inflammatory markers have been hypothesised to mediate the relationship of social class and cardiovascular disease (CVD). We investigated whether a range of inflammatory/haemostatic markers are associated with social class independent of chronic diseases and behavioural risk factors in a population-based sample of 2682 British men aged 60-79 without a physician diagnosis of CVD, diabetes or musculoskeletal disease requiring anti-inflammatory medications. Men in lower social classes had higher mean levels of C-reactive protein, fibrinogen, interleukin-6, white blood cell count, von Willebrand factor (vWF), factor VIII, activated protein C (APC) resistance, plasma viscosity, fibrin D-dimer and platelet count, compared to higher social class groups; but not of tissue plasminogen activator antigen, haematocrit or activated partial prothrombin time. After adjustment for behavioural risk factors (smoking, alcohol, physical activity and body mass), the associations of social class with vWF, factor VIII, APC resistance, plasma viscosity, and platelet count though weakened, remained statistically significant, while those of other markers were considerably attenuated. In this study of older men without CVD, the social gradient in inflammatory and haemostatic markers was substantially explained by behavioural risk factors. The effect of socio-economic gradient on the factor VIII-vWF complex, APC resistance, plasma viscosity and platelet count merits further study.

Smoking is one of the major lifestyle factors influencing the health of human beings. Life-long cigarette smokers have a higher prevalence of common diseases such as atherosclerosis and COPD with significant systemic impact. The present review evaluates current knowledge concerning possible pathways through which cigarette smoking can affect human health, with special focus on extrapulmonary effects. Long-term smoke exposure can result in systemic oxidants-antioxidants imbalance as reflected by increased products of lipid peroxidation and depleted levels of antioxidants like vitamins A and C in plasma of smokers. A low-grade systemic inflammatory response is evident in smokers as confirmed by numerous population-based studies: elevated levels of C-reactive protein (CRP), fibrinogen, and interleukin-6, as well as increased counts of WBC have been reported. Furthermore, rheologic, coagulation and endothelial function markers like hematocrit, blood and/or plasma viscosity, fibrin d-dimer, circulating adhesion molecules (intracellular adhesion molecule-1, selectins), tissue plasminogen activator antigen, and plasminogen activator inhibitor type I are altered in chronic cigarette smokers. Although most of smoking-induced changes are reversible after quitting, some inflammatory mediators like CRP are still significantly raised in ex-smokers up to 10 to 20 years after quitting, suggesting ongoing low-grade inflammatory response persisting in former smokers. New longitudinal epidemiologic and genetic studies are required to evaluate the role of smoking itself and possible gene/environment interplay in initiation and development of smoking-induced common diseases affecting humans.

Possible correlations between adiponectin, leptin, CD146, a novel adhesion molecule localized at the endothelial junction, and other markers of endothelial cell injury, von Willebrand factor, thrombomodulin, vascular cell adhesion molecule, and intracellular adhesion molecule, and markers of inflammation, tumor necrosis factor-alpha, interleukin-6, and high-sensitivity C-reactive protein in nondiabetic hemodialyzed patients with and without coronary artery disease were studied. Markers of endothelial dysfunction were elevated in hemodialyzed patients, predominantly with coronary artery disease. In multivariate analysis, kinetic urea modeling and plasminogen activator inhibitor-1 remained the only positive predictors of adiponectin. In multivariate analysis, predictors of leptin were triglycerides, tissue plasminogen activator, CD146, and coronary artery disease. In multivariate analysis, predictors of CD146 were age, hemoglobin, and adiponectin. Elevated adiponectin correlated to CD146 may be the expression of a counterregulatory response aimed at mitigating the consequences in endothelial damage and increased cardiovascular risk in renal failure. The data provide further support for a link between adipocytokines, endothelial dysfunction, cardiovascular risk, and renal failure.

We investigated the effect of atorvastatin monotherapy and combined treatment with atorvastatin and pioglitazone on intima-media thickness, vascular function and the cardiovascular risk profile. In all, 148 patients (76 male, 72 female; aged 61.4+/-6.5 years; body mass index [BMI] 29.2+/-4.1 kg/m2; mean +/- SD) with increased cardiovascular (CV) risk factors were randomised. Intima-media thickness (IMT), the augmentation index (Aix@75), the microvascular response to acetylcholine (LDF), lipid status, and plasma levels of intact proinsulin, adiponectin, interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), matrix metalloproteinase-9 (MMP-9), sCD40L, P-selectin, tissue plasminogen activator (t-PA) and blood lipids were monitored over six months. Atorvastatin treatment, alone and in combination with pioglitazone, revealed a significant regression in IMT (0.923+/-0.013 to 0.874+/-0.012 mm and 0.921+/-0.015 to 0.882+/-0.015 mm; mean +/- SEM; p<0.05 respectively) and Aix@75 (27.3+/-1.2 to 25.9+/-1.4; and 25.6+/-1.4 to 24.8+/-1.7%; p<0.05). The endothelial response to acetylcholine as measured by laser Doppler fluximetry (LDF) improved during combined treatment (373+/-57 to 576+/-153 AU; p<0.05). Addition of pioglitazone to atorva-statin resulted in significant further effects on high-sensitivity C-reactive protein (hsCRP), t-PA, P-selectin, adiponectin, triglycerides and high-density lipoprotein (HDL) cholesterol (p<0.05 respectively). Atorvastatin significantly improved IMT and vascular elasticity. Co-administration of pioglitazone provided additional effects on endothelial function, lipid profile and laboratory markers of inflammation.

Visfatin, a ubiquitous adipokine, was first described in 2005. It was found to be selectively up-regulated in the adipose tissue and to have insulin-mimetic effects. It has been reported that visfatin is associated with endothelial damage in chronic kidney disease. We investigated plasma visfatin levels (using commercially available kits) in 100 clinically stable kidney allograft recipients. We assessed visfatin markers of coagulation: thrombin-antithrombin complexes, prothrombin fragments 1 + 2; fibrinolysis: tissue plasminogen activator, plasminogen activator inhibitor, plasmin-antiplasmin complexes; endothelial function/injury: von Willebrand factor, thrombomodulin, intracellular adhesion molecule, vascular cell adhesion molecule (VCAM); inflammation: hsCRP and interleukin-6. Visfatin was significantly higher in kidney allograft recipients than in healthy volunteers. Visfatin did not differ significantly between diabetic and nondiabetics, hypertensives and normotensives, patients with and without coronary artery disease, and between male and female subjects. Type of immunosuppressive regimen (mycophenolate mofetil vs azathioprine) did not affect visfatin levels. On univariate analysis, visfatin correlated positively with prothrombin fragments 1 + 2, VCAM, creatinine, high-sensitivity C-reactive protein, and negatively with albumin. In multivariate analysis, only VCAM was associated with visfatin in kidney allograft recipients. Visfatin, which is related to markers of inflammation, may represent a novel link between inflammation and adipocytokines among long-term kidney transplant recipients.

In spite of the inhibitory effects of ethanol (EtOH) on platelet function, soft blood clots are often observed in cadaveric blood in cases of sudden death after alcohol ingestion. In order to resolve this discrepancy, we have focused on the role of vascular endothelial cells. We tried to investigate the effects of EtOH and LPS on endothelial cells from various perspectives; thrombogenic factor (Von Willebrand factor, VWF), fibrinolytic factor (tissue plasminogen activator, tPA) and inflammatory factor (Interleukin-6, IL-6). Human umbilical vein endothelial cells (HUVECs) were incubated with various concentrations of EtOH (0-160 mM) with or without LPS. Treatment with EtOH and LPS increased VWF release from HUVECs without enhancement mRNA expression. Treatment with 40 mM of EtOH also increased IL-6 release from HUVECs without enhancement mRNA expression. Although EtOH inhibited LPS-induced IL-6 mRNA expression, 20 mM of EtOH still had an increasing effect on the release of IL-6. These doses of EtOH are consistent with a moderate drunkenness level in a normal person. On the other hand, mRNA expression and release reaction of tPA were not affected by EtOH and LPS addition. In conclusion, EtOH enhances procoagulant status via VWF release and IL-6 production cooperation with LPS and may contribute to soft blood clot formation in cadaveric blood.

ecent researches have shown that the atherosclerosis is a chronic inflammatory disease. In particular, chronic inflammation plays a key role in coronary artery plaque instability and subsequent occlusive thrombosis. Inflammatory and immune mechanisms, employing monocytes, innate receptors, cytokines are suggested to be involved in atherogenesis. Among the initiation pathways of atherogenesis are innate mechanisms, such as toll-like-receptors (TLRs). TLRs are expressed in the cardiovascular system and could thus be a key link between cardiovascular diseases and the immune system. Stimulation ofthese receptors results in the activation of a diversity of intracellular signal transduction pathways and the production of pro-inflammatory cytokines, which ultimately can contribute to atherosclerotic lesion development. Thus, bacterial endotoxin is a potential source of vascular inflammation and may be an important risk factor for atherosclerosis. Many prospective studies have shown independent associations between myocardial infarction and C-reactive protein, interleukin-6, fibrinogen, von Willebrandfactor, fibrin D-dimerand tissue plasminogen activator antigen. Numerous researches antiinflammatory therapies at an atherosclerosis, are inconsistent enough, however they allow to hope for success, in preventive maintenance and treatment cardiovascular events.
