Comparing Adult Smokers Who Switched to JUUL versus Continuing Smokers: Biomarkers of Exposure and of Potential Harm and Respiratory Symptoms. Nicotine Tob Res 2024; 26:494-502. [PMID: 37837438 DOI: 10.1093/ntr/ntad197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 08/31/2023] [Accepted: 10/01/2023] [Indexed: 10/16/2023]
Abstract
OBJECTIVES Real-world evidence on exposure to harmful and potentially harmful constituents (HPHCs) and on biological effects in cigarette smokers who switch to electronic nicotine delivery systems (ENDS) can inform the health effects of switching. AIMS AND METHODS This cross-sectional, observational study assessed adults who had smoked ≥10 cigarettes/day for ≥10 years, comparing 124 continuing cigarette smokers (Smokers) to 140 former smokers who switched to JUUL-brand ENDS exclusively for ≥6 months (Switchers). Assessments included biomarkers of exposure (BOEs) to select HPHCs, biomarkers of potential harm (BOPHs) related to smoking-related diseases, psychometric assessments of dependence on cigarettes and ENDS, respectively, and respiratory symptoms. Planned analyses compared geometric means, adjusted for demographic covariates; further analyses adjusted for additional lifestyle and smoking history covariates. RESULTS Nicotine levels were significantly higher in Switchers (median time switched = 3 years), who were unusually heavy users of JUUL. All other BOEs, including NNAL and HPMA3 (primary endpoints), were significantly lower in Switchers than Smokers. Most BOPHs (sICAM-1 [primary], and eg, white blood cell count, MCP1, HbA1c) were significantly lower in Switchers than Smokers; HDL was significantly higher. Switchers reported significantly lower dependence on JUUL than Smokers did on cigarettes, and respiratory symptom scores were significantly lower among Switchers than Smokers. CONCLUSIONS Compared to continuing smokers, smokers who switched to JUUL had substantially lower exposures to multiple HPHCs, favorable differences in markers of inflammation, endothelial function, oxidative stress, and cardiovascular risk, and fewer respiratory symptoms. These findings suggest that switching from cigarettes to JUUL likely reduces smokers' health risks. IMPLICATIONS Short-term confinement studies and randomized clinical trials demonstrate that adult smokers who switch completely to ENDS experience substantial reductions in exposure to many smoking-related toxicants. This study extends those findings to longer periods of switching to JUUL-brand ENDS (almost 3 years on average) under naturalistic use conditions in real-world settings and also found that switching to JUUL resulted in favorable differences in BOPHs more proximally related to smoking-induced disease, as well as in respiratory symptoms. Smokers who switch to ENDS reduce their exposure to toxicants, likely reducing their disease risk.

Abstract
Epigenetics is a branch of molecular biology that studies modifications able to change gene expression without changing the DNA sequence. Epigenetic modulations include DNA methylation, histone modifications, and noncoding RNAs. These heritable and modifiable gene changes can be caused by lifestyle and dietary factors. In recent years, epigenetic changes have been associated with the pathogenesis of a number of diseases, such as diabetes mellitus, obesity, renal pathology and various types of cancer. They were also associated with the pathogenesis of cardiovascular diseases, including ischemic stroke. In this regard, it is important to note that since epigenetic modifications are reversible processes, they can help in the development of new therapeutic approaches to treat human diseases. This mini-review presents the latest data on the influence of epigenetic modifications on the pathogenesis of ischemic stroke obtained both in animal models and in patients.

Abstract
Background Tobacco harm reduction (THR) aims to reduce the health burden of cigarettes by encouraging smokers to switch to using alternative tobacco or nicotine products. Nicotine pouches (NPs) are smokeless, tobacco-free, oral products that may be beneficial as part of a THR strategy. Objective This 2-center, cross-sectional confinement study conducted in Denmark and Sweden aimed to determine whether biomarkers of exposure (BoEs) to tobacco toxicants and biomarkers of potential harm (BoPHs) in exclusive users of NPs show favorable differences compared with current smokers. Methods Participants were healthy NP users (target n=100) and current, former, or never smokers (target n=40 each), as confirmed by urinary cotinine and exhaled carbon monoxide concentrations. During a 24-hour confinement period, participants were asked to use their usual product (NP or cigarette) as normal, and BoEs and BoPHs were measured in blood and 24-hour urine samples, with compliance determined using anabasine, anatabine, and N-(2-cyanoethyl)valine. BoEs and BoPHs were compared between NP users and current, former, and never smokers. Urinary total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (BoE to nicotine-derived nitrosamine ketone) and urinary 8-epi-prostaglandin F2α type III, exhaled nitric oxide, blood carboxyhemoglobin, white blood cell count, soluble intercellular adhesion molecule-1, and high-density lipoprotein cholesterol (BoPHs) were evaluated as primary outcomes. Other measures included urinary 11-dehydrothromboxane B2, forced expiratory volume, carotid intima-media thickness, self-reported quality of life, and oral health. Results The results of this study were received in mid-2022 and will be published in late 2022 to early 2023. Conclusions The results of this study will provide information on toxicant exposure and biomarkers associated with the development of smoking-related diseases among users of NPs compared with smokers, as well as on the potential role of NPs in THR.

Maternal air pollution exposure during the first trimester of pregnancy and markers of inflammation and endothelial dysfunction. ENVIRONMENTAL RESEARCH 2022; 212:113216. [PMID: 35364045 DOI: 10.1016/j.envres.2022.113216] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 03/24/2022] [Accepted: 03/26/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Maternal exposure to air pollutants has been associated with pregnancy complications and adverse birth outcomes. Endothelial dysfunction, an imbalance in vascular function, during pregnancy is considered a key element in the development of pre-eclampsia. Environmental exposure to particulate matter (PM) during the first trimester of pregnancy might increase maternal inflammatory status thus affecting fetal growth, possibly leading to preterm delivery. OBJECTIVES The purpose of the study was to evaluate possible effects of PM10 and PM2.5 exposure on fetal growth in healthy pregnant women at the end of the first trimester of pregnancy by investigating the relationship between circulating biomarkers of inflammation (IL-6), early systemic prothrombotic effects (CRP, plasma fibrinogen, PAI-1) and endothelial dysfunction (sICAM-1 and sVCAM-1). METHODS 295 pregnant women were recruited. Individual PM exposure was assigned to each subject by calculating the mean of PM10 and PM2.5 daily values observed during the 30, 60, and 90 days preceding enrolment (long-term) and single lag days back to fourteen days (short-term), and circulating plasma biomarkers were determined. RESULTS For long-term exposure, we observed an increase in sVCAM-1 and a decrease of PAI-1 levels for each 10 μg/m3 increase in PM10 concentration. Decreases in IL-6 and CRP levels were associated with each 10 μg/m3 PM2.5 increase. For short-term exposure, the levels of sVCAM-1 and PAI-1 were found to be associated with PM10 exposure, whereas fibrinogen levels were associated with PM2.5 exposure. Maternal plasmatic fibrinogen levels were negatively associated with the crown-rump length (p-value = 0.008). DISCUSSION The present study showed that both long- and short-term exposures to PM are associated with changes in circulating levels of biomarkers in pregnant women reflecting systemic inflammation and endothelial dysfunction/activation. Our findings support the hypothesis that inflammation and endothelial dysfunction might have a central role in modulating the detrimental effects of air pollution exposure during pregnancy.

Effect of Endothelial Adhesion Molecules on Atrial Fibrillation: A Systematic Review and Meta-analysis. Heart Int 2022; 16:75-84. [PMID: 36741104 PMCID: PMC9872785 DOI: 10.17925/hi.2022.16.2.75] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 06/23/2022] [Indexed: 12/25/2022] Open
Abstract
Background: Endothelial adhesion molecules (EAMs), and more specifically vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1), belong to a family of immunoglobulin-like molecules and are found to have increased expression in inflamed microvessels. Due to the growing evidence regarding EAM effects on cardiovascular diseases, we aimed to investigate the link between EAMs and atrial fibrillation (AF) to discover the efficacy of EAMs assessment as predictive markers in high-risk patients. Methods: We searched for articles published from January 1990 to April 2022. Two independent researchers selected studies that examined the relationship between VCAM-1 and ICAM-1 levels and AF. Study design, patient characteristics, VCAM-1 and ICAM-1 levels, and measurement methods were extracted from the selected articles. Results: Of 181 records, 22 studies were finally included in the systematic review. Meta-analyses showed a significant difference in serum levels of EAMs in patients with AF compared with patients with sinus rhythms (VCAM-1: mean difference [MD] 86.782, 95% CI 22.805-150.758, p=0.008; ICAM-1: MD 28.439 ng/mL, 95% CI 12.540-44.338, p<0.001). In subgroup analysis of persistent AF, the differences were still significant (VCAM-1: MD 98.046, 95% CI 26.582-169.510, p=0.007; ICAM-1: MD 25.091, 95% CI 12.952-37.230, p<0.001). We also found the mean ranges of VCAM-1 (95% CI 661.394-927.984 ng/mL) and ICAM-1 (95% CI 190.101-318.169 ng/mL) in patients with AF. Conclusion: This study suggests a positive association between serum levels of VCAM-1 and ICAM-1 with AF, but there is a need for further large-scale studies.

Abstract
Background: A substantial portion of stroke risk remains unexplained, and a contribution from genetic factors is supported by recent findings. In most cases, genetic risk factors contribute to stroke risk as part of a multifactorial predisposition. A major challenge in identifying the genetic determinants of stroke is fully understanding the complexity of the phenotype. Aims: Our narrative review is needed to improve our understanding of the biological pathways underlying the disease and, through this understanding, to accelerate the identification of new drug targets. Methods: We report, the research in the literature until February 2022 in this narrative review. The keywords are stroke, causes, etiopathogenesis, genetic, epigenetic, ischemic stroke. Results: While better risk prediction also remains a long-term goal, its implementation is still complex given the small effect-size of genetic risk variants. Some authors encourage the use of stroke genetic panels for stroke risk assessment and further stroke research. In addition, new biomarkers for the genetic causes of stroke and new targets for gene therapy are on the horizon. Conclusion: We summarize the latest evidence and perspectives of ischemic stroke genetics that may be of interest to the physician and useful for day-to-day clinical work in terms of both prevention and treatment of ischemic stroke.

Abstract
Antioxidant compounds can attenuate inflammation and delay degenerative processes especially in the cardiovascular system. This study aimed to determine the relationship between dietary total antioxidant capacity (DTAC) and serum biomarkers in patients undergoing coronary artery bypass graft surgery. In this cross-sectional study, 146 patients who had referred to Imam Ali Hospital in Kermanshah were recruited and demographic, anthropometric, physical activity and dietary data were collected. Fasting blood glucose (FBG), serum levels of lipid profile, inflammatory markers (interleukin [IL]-17, intercellular and vascular cell adhesion molecules [ICAM, VCAM]), and total antioxidant capacity (TAC) were also measured. A regression model adjusted for confounding variables presented that the coefficients of ICAM and VCAM (ng/dL) in the third tertile of DTAC were lower than those in the first tertile (β = -417.2, 95% confidence interval [CI] = -509.9 to -324.5, p < 0.001; β = -293.2, 95% CI = -334.3, -252.1, p < 0.001, respectively). The β of serum TAC (ng/dL) in the third tertile was 0.86 (95% CI = 0.77, 0.95, p < 0.001) higher than that in the first tertile. DTAC had no statistically significant relationship with lipid profile, FBG, and IL-17 levels, and anthropometric indices. In this study DTAC was associated with increased serum TAC and decreased cell adhesion molecules. Therefore, diet antioxidants may be beneficial in attenuating of inflammation in coronary artery diseases.

Increased levels of VCAM-1 is associated with higher occurrence of coronary artery disease in adults with moderate to severe obstructive sleep apnea. Sleep Med 2021; 85:131-137. [PMID: 34325382 DOI: 10.1016/j.sleep.2021.07.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 06/28/2021] [Accepted: 07/01/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND Obstructive sleep apnea (OSA) leads to important vascular abnormalities, including the endothelial dysfunction and the production of endothelial cell adhesion molecules. The adhesion molecules play an important role in the process of endothelial dysfunction in the pathogenesis of atherosclerosis. We assess the relationship between the levels of adhesion molecules and the presence of coronary artery disease (CAD) in Chinese adults with moderate to severe OSA. METHODS The cross-sectional study included a total of 189 Chinese adults: 90 patients with moderate to severe OSA (apnea-hypopnea index≥15 events/h) alone, 40 patients with moderate to severe OSA and CAD, and 59 controls without OSA or with mild OSA and without CAD. We used high-throughput Multiplex Immunobead Assay technology to simultaneously test plasma levels of vascular cell adhesion molecule 1 (VCAM-1) and intercellular adhesion molecule 1 (ICAM-1). The associations between the levels of circulating adhesion molecules and CAD in moderate to severe OSA patients were evaluated by multivariate logistic regression analysis. RESULTS The circulating VCAM-1 levels were significantly elevated in patients suffering from moderate to severe OSA combined CAD compared with patients having moderate to severe OSA alone [853.28 (564.26) vs. 416.61 (301.69) ng/mL, P < 0.001]. Furthermore, circulating VCAM-1 levels were independently associated with CAD (odds ration = 2.113, 95%CI 1.400-2.766, P < 0.001) and showed higher discriminatory accuracy in assessing the presence of CAD (AUC: 0.899, 95%CI 0.849-0.950, P < 0.001) in moderate to severe OSA patients. However, no significant association was found between circulating ICAM-1 levels and CAD in moderate to severe OSA patients. CONCLUSIONS The circulating VCAM-1 levels were significantly correlated with the presence of CAD in Chinese adults with moderate to severe OSA. The circulating VCAM-1 may function as a novel biomarker for monitoring the development and progression of CAD in patients with moderate to severe OSA.

Abstract
BACKGROUND Cardiovascular disease (CVD) still remains the leading cause of morbidity and mortality worldwide. It is now established that inflammation plays a crucial role in atherosclerosis and atherothrombosis, and thus, it is closely linked to cardiovascular disease. OBJECTIVE The aim of the present review is to summarize and critically appraise the most relevant evidence regarding the potential use of inflammatory markers in the field of CVD. METHODS We conducted a comprehensive research of the relevant literature, searching MEDLINE from its inception until November 2018, primarily for meta-analyses, randomized controlled trials and observational studies. RESULTS Established markers of inflammation, mainly C-reactive protein, have yielded significant results both for primary and secondary prevention of CVD. Newer markers, such as lipoprotein-associated phospholipase A2, lectin-like oxidized low-density lipoprotein receptor-1, cytokines, myeloperoxidase, cell adhesion molecules, matrix metalloproteinases, and the CD40/CD40 ligand system, have been largely evaluated in human studies, enrolling both individuals from the general population and patients with established CVD. Some markers have yielded conflicting results; however, others are now recognized not only as promising biomarkers of CVD, but also as potential therapeutic targets, establishing the role of anti-inflammatory and pleiotropic drugs in CVD. CONCLUSION There is significant evidence regarding the role of consolidated and novel inflammatory markers in the field of diagnosis and prognosis of CVD. However, multimarker model assessment, validation of cut-off values and cost-effectiveness analyses are required in order for those markers to be integrated into daily clinical practice.

Visfatin: An emerging adipocytokine bridging the gap in the evolution of cardiovascular diseases. J Cell Physiol 2021; 236:6282-6296. [PMID: 33634486 DOI: 10.1002/jcp.30345] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 01/24/2021] [Accepted: 02/12/2021] [Indexed: 12/12/2022]
Abstract
Visfatin/nicotinamide phosphoribosyltransferase (NAMPT) is an adipokine expressed predominately in visceral fat tissues. High circulating levels of visfatin/NAMPT have been implicated in vascular remodeling, vascular inflammation, and atherosclerosis, all of which pose increased risks of cardiovascular events. In this context, increased levels of visfatin have been correlated with several upregulated pro-inflammatory mediators, such as IL-1, IL-1Ra, IL-6, IL-8, and TNF-α. Furthermore, visfatin is associated with leukocyte recruitment by endothelial cells and the production of adhesion molecules such as vascular cell adhesion molecule 1, intercellular cell adhesion molecule 1, and E-selectin, which are well known to mediate the progression of atherosclerosis. Moreover, diverse angiogenic factors have been found to mediate visfatin-induced angiogenesis. These include matrix metalloproteinases, vascular endothelial growth factor, monocyte chemoattractant protein 1, and fibroblast growth factor 2. This review aims to provide a comprehensive overview of the pro-inflammatory and angiogenic actions of visfatin, with a focus on the pertinent signaling pathways whose dysregulation contributes to the pathogenesis of atherosclerosis. Most importantly, some hypotheses regarding the integration of the aforementioned factors with the plausible atherogenic effect of visfatin are put forth for consideration in future studies. The pharmacotherapeutic potential of modulating visfatin's roles could be important in the management of cardiovascular disease, which continues to be the leading cause of death worldwide.

[PMID: 33552927 PMCID: PMC7850959 DOI: 10.1016/j.toxrep.2021.01.014] [Citation(s) in RCA: 43] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 01/21/2021] [Accepted: 01/21/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Worldwide adoption of electronic cigarettes (e-cigarettes) and heated tobacco products (HTPs) has increased exponentially over the past decade. These products have been proposed as non-combustible alternatives to traditional tobacco products such as cigarettes and may thus reduce the negative health consequences associated with tobacco smoke. However, the overall health impact and safety of using these products remains unclear. This review seeks to provide an updated summary of available evidence on changes to levels of tobacco-related biomarkers to aid the overall assessment of the consequences of using e-cigarettes and HTPs. METHODS A systematic review was conducted through major databases (Medline/PubMed, Scopus, EMBASE) searching for articles directly comparing biomarker levels in humans using e-cigarettes or HTPs and those using combustible cigarettes. We included peer reviewed articles with comparative or longitudinal design and extracted key information for our purpose (type of population, demographics, biomarkers measurements, and health effects). An initial qualitative analysis was performed followed by a summary of findings. RESULTS A total of 44 studies were included from initial citations. The vast majority of the literature reported reductions in levels of biomarkers of tobacco smoke exposure (BOE), especially nicotine, MHBMA, 3-HPMA, S-PMA, 1-OHP and NNAL, when using e-cigarettes and HTPs compared to combustible cigarettes. There was a slight tendency toward a larger reduction in these biomarkers levels with the use of e-cigarettes, although direct comparisons between e-cigarettes and HTPs were lacking. There was also a trend toward positive changes in levels of biomarkers of biological effect (BOBE) with the use of e-cigarettes and HTPs. CONCLUSIONS A comparison of levels of biomarkers of tobacco-related exposure collected in clinical studies revealed that the use of e-cigarettes and HTPs could lead to a significant reduction in exposure to harmful substances compared to combusted cigarettes. In tandem, the health status of e-cigarettes and HTP users, indexed by levels of biomarkers of biological effect showed potential for improvement compared to smoking. However, larger and longer-term population-based studies are needed to further clarify these findings.

[PMID: 33484117 DOI: 10.1093/cvr/cvab003] [Citation(s) in RCA: 59] [Impact Index Per Article: 19.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 11/17/2020] [Accepted: 01/08/2021] [Indexed: 02/06/2023] Open
Abstract
Arachidonic acid is one of the most abundant and ubiquitous ω-6 polyunsaturated fatty acid, present in esterified form in the membrane phospholipids of all mammalian cells and released from phospholipids by several phospholipases in response to various activating or inhibitory stimuli. Arachidonic acid is the precursor of a large number of enzymatically and non-enzymatically derived, biologically active autacoids, including prostaglandins (PGs), thromboxane (TX) A2, leukotrienes, and epoxyeicosatetraenoic acids (collectively called eicosanoids), endocannabinoids and isoprostanes, respectively. Eicosanoids are local modulators of the physiological functions and pathophysiological roles of blood vessels and platelets. For example, the importance of cyclooxygenase (COX)-1-derived TXA2 from activated platelets in contributing to primary haemostasis and atherothrombosis is demonstrated in animal and human models by the bleeding complications and cardioprotective effects associated with low-dose aspirin, a selective inhibitor of platelet COX-1. The relevance of vascular COX-2-derived prostacyclin (PGI2) in endothelial thromboresistance and atheroprotection is clearly shown by animal and human models and by the adverse cardiovascular effects exerted by COX-2 inhibitors in humans. A vast array of arachidonic acid-transforming enzymes, downstream synthases and isomerases, transmembrane receptors, and specificity in their tissue expression make arachidonic acid metabolism a fine-tuning system of vascular health and disease. Its pharmacological regulation is central in human cardiovascular diseases, as demonstrated by biochemical measurements and intervention trials.

Abstract
Survivors of childhood acute lymphoblastic leukemia (cALL) are at higher risk of developing cardiometabolic complications. We aimed at exploring the associations between biomarkers of inflammation, oxidative stress, endothelial function, endotoxemia and cardiometabolic risk factors. We conducted a cross-sectional analysis in 246 cALL survivors (mean age, 22.1 ± 6.3 years; mean time since diagnosis, 15.5 ± 5.2 years) and evaluated the associations using a series of logistic regressions. Using structural equation models, we also tested if the relationship between endotoxemia and cardiometabolic complications was mediated by the latent (unobserved) variable inflammation inferred from the observed biomarkers CRP, TNF-α and IL-6. High leptin-adiponectin ratio was associated with obesity [adjusted OR = 15.7; 95% CI (6.2–39.7)], insulin resistance [20.6 (5.2–82.1)] and the metabolic syndrome [11.2 (2.6–48.7)]. Higher levels of plasminogen activator inhibitor-1 and tumor necrosis factor-α were associated with obesity [3.37 (1.6–7.1) and 2.34 (1.3–4.2), respectively] whereas high C-reactive protein levels were associated with insulin resistance [3.3 (1.6–6.8)], dyslipidemia [2.6 (1.4–4.9)] and MetS [6.5 (2.4–17.9)]. Our analyses provided evidence for a directional relationship between lipopolysaccharide binding protein, related to metabolic endotoxemia, inflammation and cardiometabolic outcomes. Identification of biomarkers and biological mechanisms could open new avenues for prevention strategies to minimize the long-term sequelae, improve follow-up and optimize the quality of life of this high-risk population.

Abstract
Background Vascular cell adhesion molecule-1 (VCAM-1) is associated with vascular-related inflammation and atherosclerosis. This study aimed to evaluate whether VCAM-1 can be used for an indication of increased risk of CV events in patients with COPD. Methods Serum VCAM-1 levels were measured in 163 COPD patients. All COPD patients were prospectively followed up for a median period of 48 months (range=3-54). Cox proportional hazard analysis was performed to evaluate the prognostic value of serum VCAM-1 for predicting CV events. Results Serum VCAM-1 levels were higher in COPD patients with CV events than in those without CV events (1174.4±365.3 ng/mL vs 947.8±293.2 ng/mL; P<0.001). The logistic regression analysis revealed that serum VCAM-1 (OR=1.750; 95% CI, 1.324-2.428; Ptrend=0.0012) was independently associated with CVD (cardiovascular disease) history after adjusting for age, sex, BMI, current smoker, current drinker, admission systolic and diastolic BP, LVEF and laboratory measurements in patients with COPD at baseline. The Kaplan-Meier analysis demonstrated that the rate of CV events was higher in COPD patients with serum VCAM-1 levels above the median (517.3 ng/mL) than in those with VCAM-1 levels below the median. The Cox proportional hazard analysis revealed that serum VCAM-1 (HR=2.617; 95% CI, 1.673-5.328; Ptrend<0.001) may be an independent prognostic factor for CV events in the COPD patients. Conclusion Our results suggested that serum VCAM-1 was significantly and independently associated with CV events in COPD patients. The inflammatory marker may help clinicians predict CV complications early.

Abstract
OBJECTIVE This study aimed to investigate the effect of propylthiouracil treatment on adhesion molecules in patients with subclinical hyperthyroidism. METHODS In this study, a total of 168 patients diagnosed with subclinical hyperthyroidism were treated with propylthiouracil for one year. The levels of adhesion molecules, consisting of sICAM-1, sVCAM-1, and sE-Selectin, before and after the treatment were measured and compared. These results were compared with the levels of 148 healthy controls who received a placebo. RESULTS sICAM-1 levels were significantly higher in subclinical hyperthyroidism patients than in healthy controls (*pa=0.000). sICAM-1 levels were significantly decreased after the treatment (**pb=0.000). Despite this decrease in patients with subclinical hyperthyroidism, it did not decrease to the level of the control group. sVCAM-1 did not change before and after propylthiouracil treatment. The level of sE-selectin was similar to that of the pretreatment control group, but it did not have statistical significance, although it increased after the treatment (**pb=0.004). CONCLUSION The sICAM level was significantly higher than the pretreatment values and decreased after the propylthiouracil treatment. However, further studies are needed to reduce the risk of atherosclerosis and cancer in patients with subclinical hyperthyroidism.

Abstract
Psoriasis patients are at increased risk of atherosclerosis, characterized by endothelial dysfunction, linked through systemic inflammation. Anti-TNF-a therapy seems to decrease this risk. The purpose of this study was to measure the levels of serum markers associated with systemic inflammation in psoriasis patients, compared to healthy individuals and to investigate the change in their levels after 3 months and 2 years of adalimumab therapy. We investigated four biomarkers: high-sensitivity C-reactive protein (hsCRP), oxidized low-density lipoproteins (OxLDL), E-selectin, and Interleukin 22 (IL-22). These markers were measured in healthy volunteers and in 28 patients with moderate/severe psoriasis before and after 3 and 24 months of treatment with adalimumab. Psoriasis patients had increased levels of markers in comparison to the control group. After 3 months of therapy, E-selectin decreased significantly (P < .001), as well as IL-22 (P < .001). hsCRP also decreased but did not show a statistical significance, OxLDL were slightly higher than initially. After 24 months, 17 patients were still being treated with adalimumab. In these patients, hsCRP (P < .05), E-selectin (P < .001) and IL-22 (P < .001) were significantly decreased. OxLDL remained at a higher level. The stable decrease of E-selectin, hsCRP, and IL-22 after 24 months confirms that adalimumab suppresses systemic inflammation.

Abstract
Objective: Rheumatoid arthritis (RA) is associated with increased risk of cardiovascular disease. Adventitial vasa vasorum density (aVVD), the vessel density of the vasa vasorum, is a surrogate measure for atherosclerotic plaque vulnerability. The purpose of this study was to compare the adventitial vasa vasorum density (aVVD) in RA and non-RA control participants using novel carotid artery contrast-enhanced ultrasound (CEUS). In addition, we investigate associations of aVVD with traditional cardiovascular (CV) risk factors, vascular and inflammatory biomarkers, and RA disease activity. Methods: The study was a cross-sectional analysis of patients with RA and control participants without RA or other autoimmune disease. CV disease risk, biomarkers, and CEUS images were collected on all patients. Results: aVVD was quantified in 86 patients with RA and 95 non-RA control participants. Nitrite, CD40L, E-selectin, matrix metalloproteinase 9, intercellular adhesion molecule 1, vascular cell adhesion molecule 1, myeloperoxidase (MPO), high-sensitivity C-reactive protein (hsCRP), and erythrocyte sedimentation rate were measured. Median aVVD was higher in patients with RA (0.59 [0.47–0.69] vs 0.64 [0.54–0.62]; P = .02). In patients with RA, MPO was lower (253.5 [153.2–480] vs 470.8 [274.2–830.1] ng/mL; P = .0002) and ESR was higher (15.5 [11–25] vs 13 [9–20] mm/h; P = .02). aVVD was correlated with MPO ( r = −0.33, P = .001) and hsCRP ( r = 0.25, P = .02) in control participants only, associations that remained significant after adjusting for number of CV risk factors and age. No significant correlations were found between aVVD and RA disease activity measures. Conclusions: Using a novel application of CEUS, we found that aVVD, an early measure of plaque vulnerability, was significantly higher in RA than control subjects, even after adjusting for CV risk factors. Differences in correlation of aVVD with vascular biomarkers and CV risk factors suggest RA-related differences in atherosclerotic progression.

Abstract
Epigenetics is the branch of molecular biology that studies modifications able to change gene expression without altering the DNA sequence. Epigenetic modulations include DNA methylation, histone modifications, and noncoding RNAs. These gene modifications are heritable and modifiable and can be triggered by lifestyle and nutritional factors. In recent years, epigenetic changes have been associated with the pathogenesis of several diseases such as diabetes, obesity, renal pathology, and different types of cancer. They have also been related with the pathogenesis of cardiovascular diseases including ischemic stroke. Importantly, since epigenetic modifications are reversible processes they could assist with the development of new therapeutic approaches for the treatment of human diseases. In the present review article, we aim to collect the most recent evidence concerning the impact of epigenetic modifications on the pathogenesis of ischemic stroke in both animal models and humans.

Zhang L, Mao H. The Relationship Between Serum VCAM-1 and Alzheimer's Disease in Patients with Type 2 Diabetes Mellitus. Diabetes Metab Syndr Obes 2020; 13:4661-4667. [PMID: 33299334 PMCID: PMC7721106 DOI: 10.2147/dmso.s274232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Accepted: 10/23/2020] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Previous studies have reported that diabetes mellitus (DM) is a risk factor for Alzheimer's disease (AD). Vascular cell adhesion molecule-1 (VCAM-1) plays an important role in the pathological process of atherosclerosis. The aim was to elucidate the relationship between serum VCAM-1 and early AD in DM patients. METHODS Serum samples for VCAM-1 were tested in 208 DM patients. All included DM patients were followed up for a median of 36 months prospectively. The prognostic value of serum VCAM-1 for predicting AD events was analyzed by using Cox proportional hazard. RESULTS Serum VCAM-1 was independently associated with AD history after adjusting for related confounding factors in patients with DM at baseline by using the logistic regression analysis (OR=1.861; 95% CI, 1.435-2.539; P trend=0.020). The Cox proportional hazard model suggested that VCAM-1 was a prognostic factor for AD events in the DM patients (HR=2.728; 95% CI, 1.785-5.439; P trend<0.001). Stratified analysis showed that the significant association between AD event and serum VCAM-1 in DM patients was not affective by CVD history. CONCLUSION Our results showed that higher VCAM-1 levels were significantly related to a higher risk of AD events in DM patients. The serum biomarker might be beneficial to predict AD early. Serum VCAM-1 might be a good biochemical parameter for predicting AD in DM.

Abstract
OBJECTIVE Juvenile-onset mixed connective tissue disease (JMCTD) is a chronic inflammatory disease. We have previously demonstrated preclinical atherosclerosis in these patients, now exploring this further by assessing markers of endothelial dysfunction. METHODS Thirty-three patients with JMCTD and 33 age-and sex-matched controls were included. Soluble intercellular adhesion molecule-1 (sICAM-1), Il-6 and, von Willenbrand factor (vWF) were assayed from blood taken at the time of carotid ultrasound. RESULTS Our major findings were: (1) Levels of sICAM-1 (P < .001), IL-6 (P = .004), and vWF (P = .001) were higher, whereas (2) high density lipoprotein cholesterol (<.01) and apolipoprotein A1 (P < .01) were lower in the patient group compared to controls. CONCLUSIONS Patients with JMCTD had significantly increased levels of markers of endothelial dysfunction.

Abstract
Importance Accumulating evidence links inflammation and atrial fibrillation (AF). Objective To assess whether markers of systemic and atrial inflammation are associated with incident AF in the general population. Design, Setting, and Participants The Bruneck Study is a prospective, population-based cohort study with a 20-year follow-up (n = 909). The population included a random sample of the general community aged 40 to 79 years. Levels of 13 inflammation markers were measured at baseline in 1990. Findings were replicated in a case-control sample nested within the prospective Salzburg Atherosclerosis Prevention Program in Subjects at High Individual Risk (SAPHIR) study (n = 1770). Data analysis was performed from February to May 2016. Exposures Levels of 13 inflammation markers. Main Outcomes and Measures Incident AF over a 20-year follow-up period in the Bruneck Study. Results Of the 909 participants included in the Bruneck Study, mean [SD] age was 58.8 (11.4) years and 448 (49.3%) were women. Among the 880 participants free of prevalent AF (n = 29) at baseline, 117 developed AF during the 20-year follow-up period (incidence rate, 8.2; 95% CI, 6.8-9.6 per 1000 person-years). The levels of soluble vascular cell adhesion molecule 1 (VCAM-1) and osteoprotegerin were significantly associated with incident AF (hazard ratio [HR], 1.49; 95% CI, 1.26-1.78; and 1.46; 95% CI, 1.25-1.69, respectively; P < .001 with Bonferroni correction for both), but osteoprotegerin lost significance after age and sex adjustment (HR, 1.05; 95% CI, 0.87-1.27; P > .99 with Bonferroni correction). Matrix metalloproteinase 9, metalloproteinase inhibitor 1, monocyte chemoattractant protein-1, P-selectin, fibrinogen, receptor activator of nuclear factor-κB ligand, high-sensitivity C-reactive protein, adiponectin, leptin, soluble intercellular adhesion molecule 1, and E-selectin all fell short of significance (after Bonferroni correction in unadjusted and age- and sex-adjusted analyses). The HR for a 1-SD higher soluble VCAM-1 level was 1.34 (95% CI, 1.11-1.62; Bonferroni-corrected P = .03) in a multivariable model. The association was of a dose-response type, at least as strong as that obtained for N-terminal pro-B-type natriuretic peptide (multivariable HR for a 1-SD higher N-terminal pro-B-type natriuretic peptide level, 1.15; 95% CI, 1.04-1.26), internally consistent in various subgroups, and successfully replicated in the SAPHIR Study (age- and sex-adjusted, and multivariable odds ratios for a 1-SD higher soluble VCAM-1 level, 1.91; 95% CI, 1.24-2.96, P = .003; and 2.59; 95% CI, 1.45-4.60; P = .001). Conclusions and Relevance Levels of soluble VCAM-1, but not other inflammation markers, are significantly associated with new-onset AF in the general community. Future studies should address whether soluble VCAM-1 is capable of improving AF risk classification beyond the information provided by standard risk scores.

Biomarkers of vascular injury in relation to myocardial infarction risk: A population-based study. Sci Rep 2019; 9:3004.

Abstract
Little is known about circulating biomarkers of vascular injury in relation to cardiovascular disease risk. Thus, we evaluated associations between six novel markers (E-Selectin, P-Selectin, thrombomodulin, thrombopoietin, intercellular adhesion molecule 3 and GPIIb/IIIa) and established cardiovascular risk factors as well as the risk of myocardial infarction (MI) in a population-based study. Biomarkers were measured in pre-diagnostic plasma samples of a case-cohort subset of EPIC-Heidelberg (incident MI cases: n = 369, random sub-cohort: n = 2,418). Generalized Linear models were used to analyse cross-sectional associations between biomarkers and cardiovascular risk factors. Multivariable Cox Regression analyses were carried out to obtain Hazard Ratios (HRs) of MI across quartiles of biomarkers levels. Cross-sectional analyses showed that sex, smoking, alcohol consumption, diabetes and exogenous hormone use were associated with biomarker levels. However, while fibrinogen was associated with MI risk (HR per standard deviation: 2.97 [95% confidence interval: 1.61, 5.46]), none of the six novel biomarkers was associated with MI risk after multivariable adjustment. In a population-based cohort, biomarkers of vascular injury were associated with established cardiovascular risk factors, but not MI risk. The tested biomarkers may reflect pathophysiological alterations in cardiovascular disease development rather than constituting independent MI risk factors.

Abstract
OBJECTIVE Women with gestational diabetes mellitus and milder gestational impaired glucose intolerance have elevated future risks of type 2 diabetes and cardiovascular disease. However, it is unclear whether they show postpartum evidence of vascular injury/dysfunction, an early event in the natural history of cardiovascular disease. METHODS In total, 337 women underwent a glucose challenge test and oral glucose tolerance test in pregnancy, yielding four gestational glucose tolerance groups: gestational diabetes mellitus, gestational impaired glucose intolerance, abnormal glucose challenge test with normal glucose tolerance on the oral glucose tolerance test and normal glucose challenge test with normal glucose tolerance. At 3 years postpartum, they underwent repeat oral glucose tolerance test (on which 69 women had pre-diabetes/diabetes) and measurement of the following serum markers of vascular injury/dysfunction: thrombomodulin, E-selectin, P-selectin, intercellular adhesion molecule-3 and vascular cell adhesion molecule-1. RESULTS At 3 years postpartum, mean adjusted vascular cell adhesion molecule-1 was the only vascular marker that differed across the previous gestational glucose tolerance groups. On multiple linear regression analysis, each strata of gestational dysglycaemia was an independent predictor of lower vascular cell adhesion molecule-1 at 3 years postpartum (gestational diabetes mellitus: p = 0.005; gestational impaired glucose intolerance: p = 0.003; abnormal glucose challenge test normal glucose tolerance: p = 0.0008), as was current pre-diabetes/diabetes ( p = 0.01). CONCLUSION Dysregulation of vascular cell adhesion molecule-1 may be an early event in the natural history of cardiovascular disease in women with recent glucose intolerance in pregnancy.

Abstract
Studies on the inflammatory burden in recent-onset psoriatic arthritis (PsA) patients without conventional cardiovascular risk factors (CVRFs) are not available. This preliminary study focuses on cardiovascular risk in cutaneous psoriasis (CPs) and recent-onset PsA patients. Blood biochemistry (glucose, cholesterol, uric acid, lipid profile and apolipoprotein B) was analyzed using standard kits. Proatherogenic inflammation markers, C-reactive protein (CRP) and interleukin-6 (IL-6), and endothelial activators monocyte chemoattractant protein-1 (MCP-1) and soluble intercellular adhesion molecule-1 (sICAM-1), were determined by enzyme-linked immunosorbent assay. Ultrasound images allowed measuring carotid intima-media thickness (cIMT). Our study first shows an increase in cIMT, and in serum levels of sICAM-1 and CRP in recent-onset PsA patients not presenting conventional CVRFs over the non-medicated time-period, from disease diagnosis to the beginning of pharmacological treatment, compared with healthy subjects. The outcome highlights the importance of monitoring serum level of sICAM1, CRP, and cIMT, and the value of primary prevention in psoriatic patients even with no history of cardiovascular events.

Abstract
Context: One approach to reducing the harm caused by cigarette smoking, at both individual and population level, is to develop, assess and commercialize modified risk alternatives that adult smokers can switch to. Studies to demonstrate the exposure and risk reduction potential of such products generally involve the measuring of biomarkers, of both exposure and effect, sampled in various biological matrices.Objective: In this review, we detail the pros and cons for using several biomarkers as indicators of effects of changing from conventional cigarettes to modified risk products.Materials and methods: English language publications between 2008 and 2017 were retrieved from PubMed using the same search criteria for each of the 25 assessed biomarkers. Nine exclusion criteria were applied to exclude non-relevant publications.Results: A total of 8876 articles were retrieved (of which 7476 were excluded according to the exclusion criteria). The literature indicates that not all assessed biomarkers return to baseline levels following smoking cessation during the study periods but that nine had potential for use in medium to long-term studies.Discussion and conclusion: In clinical studies, it is important to choose biomarkers that show the biological effect of cessation within the duration of the study.

Abstract
Thioredoxin-interacting protein (TXNIP) emerges as a central regulator for glucose homeostasis, which goes awry in diabetic subjects. Endothelial dysfunction is considered the earliest detectable stage of cardiovascular disease (CVD), a major complication of diabetes. Here, we hypothesize that TXNIP may promote endothelial dysfunction seen in Type 1 diabetes mellitus (T1D). Using a T1D-like rat model, we found that diabetic rats showed significantly higher TXNIP mRNA and protein levels in peripheral blood, compared to their non-diabetic counterparts. Those changes were accompanied by decreased production of nitric oxide (NO) and vascular endothelial growth factor (VEGF), concurrent with increased expression of reactive oxygen species (ROS) and vascular cell adhesion molecule 1 (VCAM-1) in the aortic endothelium. In addition, TXNIP overexpression in primary human aortic endothelial cells (HAECs) induced by either high glucose or overexpression of carbohydrate response element binding protein (ChREBP), a major transcriptional activator of TXNIP, promoted early apoptosis and impaired NO bioactivity. The correlation between TXNIP expression levels and endothelial dysfunction suggests that TXNIP may be a potential biomarker for vascular complications in T1D patients.

Abstract
BACKGROUND Cell adhesion molecules are key regulators of atherosclerotic plaque development, but circulating levels of soluble fragments, such as intercellular adhesion molecule (sICAM-1) and vascular cell adhesion molecule (sVCAM-1), have yielded conflicting associations with atherosclerotic cardiovascular disease (ASCVD). Endothelial cell-selective adhesion molecule (ESAM) is expressed exclusively in platelets and endothelial cells, and soluble ESAM (sESAM) levels have been associated with prevalent subclinical atherosclerosis. We therefore hypothesized that sESAM would be associated with incident ASCVD. METHODS sESAM, sICAM-1, and sVCAM-1 were measured in 2,442 participants without CVD in the Dallas Heart Study, a probability-based population sample aged 30-65 years enrolled between 2000 and 2002. ASCVD was defined as first myocardial infarction, stroke, coronary revascularization, or CV death. A total of 162 ASCVD events were analyzed over 10.4 years. RESULTS Increasing sESAM was associated with ASCVD, independent of risk factors (HR Q4 vs Q1: 2.7, 95% CI 1.6-4.6). Serial adjustment for renal function, sICAM-1, VCAM-1, and prevalent coronary calcium did not attenuate these associations. Continuous ESAM demonstrated similar findings (HR 1.31, 95% CI 1.2-1.4). Addition of sESAM to traditional risk factors improved discrimination and reclassification (delta c-index: P = .009; integrated-discrimination-improvement index P = .001; net reclassification index = 0.42, 95% CI 0.15-0.68). Neither sICAM-1 nor sVCAM-1 was independently associated with ASCVD. CONCLUSIONS sESAM but not sICAM-1 or sVCAM-1 levels are associated with incident ASCVD. Further studies are warranted to investigate the role of sESAM in ASCVD.

Abstract
To quantify myocardial edema by using a T2 relaxometry approach with a dual-contrast turbo spin-echo (dcTSE) sequence in patients with acute myocarditis regarding focal late gadolinium enhancement (LGE) burden. CMR T2 relaxometry was performed in 39 patients (age 41 ± 19 years; 36% women) with LGE in a typical myocarditis pattern and in ten healthy volunteers (age 46 ± 12; 60% woman). dcTSE sequence (echo time 29 and 75 ms, respectively) was used for T2 mapping, analysis were performed on the basis of region of interest (ROI). Myocardial T2 relaxation times (T2 RT) in patients-ROI with focal LGE were significantly (p < 0.001) higher than T2 RT in patients-ROI without apparent LGE pattern (65 ms (IQR 36-95) vs. 60 ms (IQR 26-88), respectively). T2 RT in healthy volunteers [55 ms (IQR 35-71)] were significantly lower than in patients ROI with or without focal LGE-pattern (p < 0.001, respectively). T2 RT assessed by dcTSE are significantly higher in patients segments with and without focal LGE compared to normal controls, supporting a global myocardial inflammatory process in acute myocarditis. Furthermore, this quantitative T2-mapping approach highlights the potential to identify patients with diffuse myocarditis.

Abstract
INTRODUCTION Although it has been suggested that increased concentrations of activated platelet biomarkers are associated with increased risk of incident cardiovascular disease (CVD) in the general population, evidence for this association is still controversial. Thus, we tested the hypothesis that activated platelets, measured by higher concentrations of β-thromboglobulin, are associated with increased risk of incident CVD (coronary heart disease, heart failure ischemic stroke, and atrial fibrillation). MATERIALS AND METHODS We prospectively followed a cohort random sample of the Atherosclerosis Risk in Communities (ARIC) cohort, aged 45-64years, and free of CVD at baseline who had previous measurements of plasma β-thromboglobulin. We identified incident CVD from 1987 through 2013, and used a weighted Cox proportional hazard models to estimate hazard ratios (HRs) and their 95% confidence intervals (CIs). RESULTS During the 14,387person-years of follow-up for the 746 participants, we identified 140 coronary heart diseases, 123 heart failures, 54 ischemic strokes, and 126 atrial fibrillations. The age-, sex-, and race-adjusted model showed no association between plasma β-thromboglobulin and CVD, regardless of subtypes. After further adjustment for other CVD risk factors, including antiplatelet agent use, β-thromboglobulin remained unassociated with CVD risk. CONCLUSIONS In the prospective population-based ARIC cohort, β-thromboglobulin was not associated with CVD risk. Our results do not support the hypothesis that a blood marker of higher platelet activity reflects increased future risk of CVD in the general population.

Abstract
Background Familial hypercholesterolaemia (FH) leads to premature coronary artery diseases (CAD) which pathophysiologically can be measured by inflammation, endothelial activation and oxidative stress status. However, the status of these biomarkers among related unaffected relatives of FH cases and whether FH is an independent predictor of these biomarkers have not been well established. Thus, this study aims to (1) compare the biomarkers of inflammation, endothelial activation and oxidative stress between patients with FH, their related unaffected relatives (RUC) and normolipaemic subjects (NC) (2)determine whether FH is an independent predictor of these biomarkers. Methods One hundred thirty-one FH patients, 68 RUC and 214 matched NC were recruited. Fasting lipid profile, biomarkers of inflammation (hsCRP), endothelial activation (sICAM-1 and E-selectin) and oxidative stress [oxidized LDL (oxLDL), malondialdehyde (MDA) and F2-isoprostanes (ISP)] were analyzed and independent predictor was determined using binary logistic regression analysis. Results hsCRP was higher in FH and RUC compared to NC (mean ± SD = 1.53 ± 1.24 mg/L and mean ± SD = 2.54 ± 2.30 vs 1.10 ± 0.89 mg/L, p < 0.05). sICAM-1 and E-selectin were higher in FH compared to NC (mean ± SD = 947 ± 742 vs 655 ± 191 ng/mL, p < 0.001 and 175 ± 131 vs 21.6 ± 10.7 ng/mL, p < 0.001 respectively) while sICAM-1 concentration was higher in RUC compared to NC (mean ± SD = 945 ± 379 vs 655 ± 191 ng/mL, p < 0.01). Biomarkers of oxidation (ox-LDL, MDA and ISP) were elevated in FH compared to NC [mean ± SD = (48.2 ± 26.8 vs 27.3 ± 13.2 mU/L, p < 0.001), (2.57 ± 1.3 vs 1.20 ± 0.30 nmol/mL, p < 0.001) and (645 ± 396 vs 398 ± 20.5 pg/L, p < 0.001) respectively], but no significant differences were observed between RUC and NC (p > 0.05). FH was an independent predictor for sICAM-1 (p = 0.007), ox-LDL (p < 0.001) and MDA (p < 0.001) while RUC independently predicted for sICAM-1 (p < 0.001). Conclusion The screening for FH is vital as all biomarkers associated with atherogenesis are higher in these subjects and FH also independently predict biomarkers of endothelial activation and oxidative stress. Furthermore, despite not fulfilling the diagnostic criteria for FH, related unaffected family members that may not phenotypically express the mutation may still be at risk of developing CAD as reflected from the enhanced inflammatory and endothelial activation status observed in this group. This highlights the need to not only conduct family tracing in indexed FH cases, but also assess the coronary risk among family members that do not fulfil the FH diagnostic criteria.

Abstract
Psoriasis is a chronic systemic immune-mediated inflammatory dermatosis associated with several comorbidities. Psoriasis patients are at increased risk of developing cardiovascular diseases (CVD), namely, coronary heart disease, stroke or peripheral vascular disease, and psoriasis seems to be an independent cardiovascular risk factor. Antipsoriatic systemic therapy, especially anti-tumor necrosis factor (TNF)-α, seems to exert a beneficial effect on these comorbidities. The purpose of this study was: (i) to measure the level of cardiovascular serum markers in psoriasis patients in comparison with healthy volunteers; and (ii) to compare the serum level of the same markers in patients before and 3 months after adalimumab therapy. We investigated six biomarkers connected to CVD: C-reactive protein (measured high sensitively, hsCRP), oxidized low-density lipoproteins (oxLDL), oxLDL/β-glycoprotein I complex (oxLDL/β2GPI), vascular endothelial adhesion molecule 1 (VCAM-1), E-selectin and interleukin (IL)-22. These biomarkers were measured in 21 patients with moderate/severe psoriasis before and after treatment with adalimumab and in healthy volunteers. hsCRP (P < 0.05), oxLDL-β2GPI complex (P < 0.05), E-selectin (P < 0.001) and IL-22 (P < 0.001) were significantly increased in comparison with healthy controls, whereas oxLDL and VCAM-1 were also higher in psoriasis patients but the difference did not reach statistical significance. A decrease of E-selectin (P < 0.001) and IL-22 (P < 0.001) was observed after 3 months of adalimumab therapy. Inhibition of TNF-α seems to not only improve psoriasis but also decreases serum cardiovascular biomarkers. E-selectin and IL-22 could serve for monitoring of the efficacy of antipsoriatic systemic therapy on cardiovascular risk.

Abstract
Depressive disorders represent a frequent comorbidity of both type 1 (T1D) and type 2 diabetes (T2D). Inflammation-related processes have been implicated in the development of both diabetes and depression. This study aimed to investigate whether biomarkers of subclinical inflammation were associated with depressive symptoms in individuals with recently diagnosed diabetes and if such associations differed by diabetes type. This cross-sectional study was based on 295 individuals with T2D (67% men, mean age 53years) and 139 individuals with T1D (60% men, mean age 36years) of the German Diabetes Study. The main inclusion criterion was a known disease duration of <1year. Depressive symptoms were assessed with the Allgemeine Depressionsskala, Langversion (ADS-L) questionnaire, the German version of the Center for Epidemiological Studies Depression scale (CES-D) questionnaire. Associations between biomarkers of subclinical inflammation and the ADS-L as continuous score were assessed using multiple linear regression models adjusting for age, sex, body mass index, HbA1c, lipids, hypertension, medication and comorbidities. Serum high-sensitivity C-reactive protein (hsCRP) and the ratio of high-molecular-weight (HMW)/total adiponectin were positively associated with ADS-L in T2D (both P<0.01), but not in T1D. In contrast, serum levels of soluble intercellular adhesion molecule (sICAM)-1 were positively associated with ADS-L only in T1D (P=0.035). The latter association was significantly different between both diabetes types (Pinteraction=0.036). No associations were observed for interleukin (IL)-6, IL-18 and soluble E-selectin. Only the association between HMW/total adiponectin and ADS-L in T2D remained significant after correction for multiple testing. In conclusion, our study shows that the ratio HMW/total adiponectin is associated with depressive symptoms in individuals with recently diagnosed T2D. It also provides suggestive evidence that further biomarkers of subclinical inflammation and endothelial activation may be associated with depressive symptoms in individuals with recently diagnosed T1D and T2D.

Abstract
Aim: Soluble cell adhesion molecules, such as vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1, E-selectin, and P-selectin, have been suggested to be associated with cardiovascular disease (CVD) risk; however, the nature and magnitude of the association between VCAM-1 and CVD risk is uncertain. We aimed to assess the association of VCAM-1 with CVD risk and determine its potential utility for CVD risk prediction. Methods: VCAM-1 concentrations were measured at baseline in the PREVEND prospective study of 2,638 participants. Hazard ratios (95% confidence intervals [CI]) and measures of risk discrimination for CVD (e.g., C-index) and reclassification (i.e., net reclassification improvement) of participants were assessed. Results: During a median follow-up of 9.9 years, 614 CVD events occurred. Plasma VCAM-1 was weakly associated with several cardiovascular risk markers. In analyses adjusted for established cardiovascular risk factors, the hazard ratio (95% CI) for CVD per 1 standard deviation increase in loge VCAM-1 was 0.91 (0.84–0.99; P = 0.020), which remained consistent after additional adjustment for body mass index, alcohol consumption, triglycerides, renal function, and C-reactive protein; hazard ratio (95% CI) 0.89 (0.82–0.97; P = 0.006). Comparing the top versus bottom quintiles of VCAM-1 levels, the corresponding adjusted hazard ratios were 0.74 (0.57–0.96; P = 0.023) and 0.70 (0.54–0.91; P = 0.007) respectively. Adding VCAM-1 to a CVD risk prediction model containing conventional risk factors did not improve the C-index or net reclassification. Conclusions: Plasma VCAM-1 is inversely and independently associated with CVD. However, VCAM-1 provides no significant improvement in CVD risk assessment beyond conventional CVD risk factors.

Abstract
Atherosclerosis and its late sequels are still the number one cause of death in Western societies. Platelets are a driving force not only during the genesis of atherosclerosis, but especially in its late stages, as evidenced by complications such as arterial thrombosis, myocardial infarction, and ischaemic stroke. Platelets are small, anucleate blood elements of critical importance in cardiovascular disease, a major cause of morbidity and mortality. Numerous risk scores exist to identify healthy individuals at increased risk of developing atherosclerosis and cardiovascular disease. However, markers of cardiovascular risk not routinely assessed (i.e. platelet activity, mean platelet volume and P-selectin) may also contribute to be useful in calculating cardiovascular risk. The present review and meta-analysis summarizes the evidence for measuring platelet function indices to identify patients at risk of developing cardiovascular events.

Abstract
Background: Aortic stenosis is an inflammatory process, as evidenced by increased tissue expression and serum levels of various endothelial cellular adhesion molecules. Aortic stenosis and atherosclerosis have many risk factors in common, including hypercholesterolemia. In atherosclerosis, statins lower cholesterol and display some anti-inflammatory activity. We hypothesized that statins might also have anti-inflammatory effects in patients with aortic stenosis. Methods: This observational cross-sectional study measured levels of cellular adhesion molecules in 129 patients (88 male, mean age 68) with aortic stenosis (mean echo gradient 49 mm Hg, range 22 to 112) and compared levels in patients already on statin therapy for primary or secondary prevention of coronary artery disease, to those not on treatment. Concomitant conditions included hypertension (47%), diabetes (10%), and ischemic heart disease (54%). A comparison group consisted of 45 patients with stable ischemic heart disease. Results: Patients on statins (35) were more likely to have hypertension (62% vs 42%, P = .05), but no significant differences existed in sex, age, concomitant ischemic heart disease, or diabetes. Statin-treated patients had a 20% lower vascular cellular adhesion molecule level than those without (484 ± 143 ng/L vs 604 ± 245 ng/L, P = .006). The reduction in cellular adhesion molecule levels was consistent in patients with aortic stenosis alone, aortic stenosis and ischemic heart disease, or ischemic heart disease alone. There were no differences in the levels of the other adhesion molecules between the three groups, or related to statin therapy. Conclusion: Statin therapy is associated with reduced serum levels of vascular cellular adhesion molecules in patients with aortic stenosis. Vascular cellular adhesion molecule levels are similar in patients who have aortic stenosis, ischemic heart disease, or both. A prospective study is required to confirm this finding and to determine whether this suppression of endothelial inflammation translates into a slowing of the progression of aortic stenosis.

Abstract
The effective prevention of cardiovascular disease depends upon the ability to recognize the high-risk individuals at an early stage of the disease or long before the development of adverse events. Evolving technologies in the fields of proteomics, metabolomics, and genomics have played a significant role in the discovery of cardiovascular biomarkers, but so far these methods have achieved the modest success. Hence, there is a crucial need for more reliable, suitable, and lasting diagnostic and therapeutic markers to screen the disease well in time to start the clinical aid to the patients. Gene polymorphisms associated with the cardiovascular disease play a decisive role in the disease onset. Therefore, the genetic marker evaluation to classify high-risk patients from low-risk patients trends an effective approach to patient management and care. Currently, there are no genetic markers available for extensive adoption as risk factors for coronary vascular disease, yet, there are numerous promising, biologically acceptable candidates. Many of these gene biomarkers, alone or in combination, can play an essential role in the prediction of cardiovascular risk. The present review highlights some putative emerging genetic biomarkers that could facilitate more authentic and fast diagnosis of CVD. This review also briefly describes few technological approaches employed in the biomarker search.

Inhibition of platelet function with clopidogrel is associated with a reduction of inflammation in patients with peripheral artery disease. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2016; 17:169-75. [PMID: 27157293 DOI: 10.1016/j.carrev.2016.01.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2015] [Revised: 01/08/2016] [Accepted: 01/25/2016] [Indexed: 11/23/2022]
Abstract
BACKGROUND The reactivity of platelets is increased in patients with peripheral artery disease (PAD). RANTES and sCD40L are chemokines which are stored in the alpha-granules of platelets. Clopidogrel inhibits and thus reduces platelet reactivity. Whether a treatment with clopidogrel is associated with an inhibition of systemic inflammation in patients with PAD has not been thoroughly explored. This study examined the effect of clopidogrel on platelet reactivation and the release of inflammatory chemokines in patients with PAD. METHODS 40 patients with PAD were randomized into two groups. In the first group A the patients were treated with 100mg acetylsalicylic acid (ASA) and additional placebo for 4weeks. The patients in group B received 75mg/d clopidogrel in addition to ASA 100mg for 4weeks. After obtaining blood at days 0, 7 and 28 the platelet activation was determined by measuring the surface protein expression of CD63, CD62p and thrombospondin (TSP) after stimulation with TRAP and ADP. The release of the chemokines RANTES and sCD40L from platelets was analyzed by ELISA. RESULTS Platelet activation markers (CD62p and CD63) and chemokine RANTES were significantly reduced in patients with PAD after 7 and 28days after treatment with clopidogrel. No alterations were found in TSP expression and sCD40L during the treatment. CONCLUSION The treatment with clopidogrel leads to a reduction of platelet reactivity and release of RANTES from the platelets of patients with PAD.

Abstract
OBJECTIVES Although psychological factors have been associated with chronic diseases such as coronary heart disease (CHD), the underlying pathways for these associations have yet to be elucidated. DNA methylation has been posited as a mechanism linking psychological factors to CHD risk. In a cohort of community-dwelling elderly men, we explored the associations between positive and negative psychological factors with DNA methylation in promoter regions of multiple genes involved in immune/inflammatory processes related to atherosclerosis. DESIGN Prospective cohort study. SETTING Greater Boston, Massachusetts area. PARTICIPANTS Samples of 538 to 669 men participating in the Normative Aging Study cohort with psychological measures and DNA methylation measures, collected on 1-4 visits between 1999 and 2006 (mean age=72.7 years at first visit). OUTCOME MEASURES We examined anxiety, depression, hostility and life satisfaction as predictors of leucocyte gene-specific DNA methylation. We estimated repeated measures linear mixed models, controlling for age, smoking, education, history of heart disease, stroke or diabetes, % lymphocytes, % monocytes and plasma folate. RESULTS Psychological distress measured by anxiety, depression and hostility was positively associated, and happiness and life satisfaction were inversely associated with average Intercellular Adhesion Molecule-1 (ICAM-1) and coagulation factor III (F3) promoter methylation levels. There was some evidence that hostility was positively associated with toll-like receptor 2 (TLR-2) promoter methylation, and that life satisfaction was inversely associated with TLR-2 and inducible nitric oxide synthase (iNOS) promoter methylation. We observed less consistent and significant associations between psychological factors and average methylation for promoters of the genes for glucocorticoid receptor (NR3C1), interferon-γ (IFN-γ) and interleukin 6 (IL-6). CONCLUSIONS These findings suggest that positive and negative psychological factors affect DNA methylation of selected genes involved in chronic immune/inflammatory processes and inflammation-related endothelial dysfunction. Such epigenetic changes may represent biological pathways that mediate the effects of psychological factors on CHD.

Abstract
BACKGROUND Atherosclerosis begins in childhood with the occurrence of inflammatory vascular wall alterations that are detectable with B-mode ultrasound. Chemokines appear to be involved in the development of these alterations given that they occur early in the atherosclerotic pathway as mediators of vascular inflammation. However, this has not extensively been investigated. Therefore, we studied in healthy young children whether chemokines monocyte chemotactic protein 1 (MCP-1), regulated on activation normal T-cell expressed and secreted (RANTES), and vascular and intercellular adhesion molecules (VCAM and ICAM) related to vascular characteristics of the carotid artery. METHODS AND RESULTS We obtained demography, anthropometry, and overnight fasting plasma of 139 eight-year-old children of the Wheezing Illnesses Study Leidsche Rijn birth cohort. Carotid intima-media thickness (CIMT), distensibility, and Young's Elastic Modulus (YEM) of the common carotid artery were measured sonographically. Chemokine plasma levels were assessed using a multiplex assay. We studied the relation between the chemokines and vascular characteristics using multivariable linear regression analyses with adjustments for sex, systolic blood pressure, homeostasis model assessment of insulin resistance, triglycerides, low-density lipoprotein- and high-density lipoprotein-cholesterol. Of the studied chemokines, RANTES related to common carotid distensibility and YEM. One standard deviation increase in RANTES level related to a 5.45-MPA(-1) (95% confidence interval [CI], -9.43, -1.39; P=0.01) decrease in distensibility and to a 5.55-kPa increase in YEM (95% CI, 0.40, 10.85; P=0.03). RANTES did not relate to CIMT. MCP-1, VCAM, and ICAM did not relate to any of the studied vascular characteristics. CONCLUSION RANTES appears to be involved in the development of preatherosclerotic inflammatory vascular alterations already in healthy, young children. This may provide further insight into the early-life origins of atherosclerosis.

Abstract
Aim VCAM-1 and ICAM-1 are two important members of the immunoglobulin gene superfamily of adhesion molecules, and their potential role as biomarkers of diagnosis, severity and prognosis of cardiovascular disease has been investigated in a number of clinical studies. The aim of the present study was to determine the relationship between circulating ICAM-1 and VCAM-1 levels and aortic stiffness in patients referred for echocardiographic examination. Methods Aortic distensibility was determined by echocardiography using systolic and diastolic aortic diameters in 63 consecutive patients referred for echocardiography. Venous samples were collected in the morning after a 12-hour overnight fast, and serum concentrations of ICAM-1 and VCAM-1 were measured using commercial enzyme immunoassay kits. Results Data of a total of 63 participants (mean age 55.6 ± 10.5 years, 31 male) were included in the study. Circulating levels of adhesion molecules were VCAM-1: 12.604 ± 3.904 ng/ml and ICAM-1: 45.417 ± 31.429 ng/ml. We were unable to demonstrate any correlation between indices of aortic stiffness and VCAM-1 and ICAM-1 levels. Conclusion The role of soluble adhesion molecules in cardiovascular disease has not been fully established and clinical studies show inconsistent results. Our results indicate that levels of circulating adhesion molecules cannot be used as markers of aortic stiffness in patients.

Abstract
When cardiovascular diseases are viewed from an evolutionary biology perspective, a heightened thrifty and an inflammatory design could be their mechanisms. Human ancestors confronted a greater infectious load and were subjected to the selection for proinflammatory genes and a strong inflammatory function. Ancestors also faced starvation periods that pressed for a thrifty genotype which caused fat accumulation. The pressure of sustaining gluconeogenesis during periods of poor nourishment selected individuals with insulin resistance. Obesity induces a proinflammatory state due to the secretion of adipokines which underlie cardiometabolic diseases. Our actual lifestyle needs no more of such proinflammatory and thrifty genotypes and these ancestral genes might increase predisposition to diseases. Risk factors for atherosclerosis and diabetes are based on inflammatory and genetic foundations that can be accounted for by excess fat. Longevity has also increased in recent times and is related to a proinflammatory response with cardiovascular consequences. If human ancestral lifestyle could be recovered by increasing exercise and adapting a calorie restriction diet, obesity would decrease and the effects on chronic low-grade inflammation would be limited. Thereby, the rates of both atherosclerosis and diabetes could be reduced.

Abstract
OBJECTIVES Monocyte activation, endothelial dysfunction and platelet activation all potentially contribute to the increased risk of cardiovascular disease (CVD) reported in those with HIV-1 infection. To date, no study has examined how initiation of antiretroviral therapy (ART) affects markers of all three processes. We aimed to compare markers of monocyte, endothelial and platelet function between untreated HIV-positive subjects and HIV-negative controls and to examine the early effects of ART initiation on these markers. METHODS We measured monocyte [soluble CD14 (sCD14) and sCD163], endothelial [von Willebrand factor (vWF), intercellular adhesion molecule-1 (ICAM-1) and vascular adhesion molecule-1 (VCAM-1)] and platelet [soluble P-selectin (sP-selectin), soluble CD40 ligand (sCD40L) and soluble glycoprotein VI (sGPVI)] biomarkers before and at weeks 4 and 12 post ART initiation in HIV-positive and well-matched HIV-negative controls. RESULTS We examined 40 subjects, 25 HIV-positive subjects and 15 controls, with a median age of 34 years [interquartile range (IQR) 31, 40 years], of whom 60% were male and 47.5% Caucasian. Pre-ART, all biomarkers (monocyte, endothelial and platelet) were significantly higher in HIV-positive patients versus controls (all P < 0.05) and decreased with ART initiation, except for sCD14, which remained unchanged [median 1680 (IQR 1489, 1946) ng/mL at week 12 versus 1570 (IQR 1287, 2102) ng/mL at week 0; P = 0.7]. Although platelet activation markers reduced to levels comparable to those in controls, endothelial dysfunction markers remained elevated, as did sCD163 [at week 12, median 1005 (IQR 791, 1577) ng/mL in HIV-positive patients versus 621 (IQR 406, 700) ng/mL in controls; P < 0.0001]. CONCLUSIONS ART initiation resulted in reductions in levels of CVD-associated biomarkers; however, although they improved, markers of endothelial dysfunction and monocyte activation remained elevated. How these persistent abnormalities affect CVD risk in HIV infection remains to be determined.

Effects of A379V variant of the Lp-PLA 2 gene on Lp-PLA 2 activity and markers of oxidative stress and endothelial function in Koreans. J Thromb Thrombolysis 2015; 38:477-84.

Abstract
A379V variant in the lipoprotein-associated phospholipase A2 (Lp-PLA 2) gene is known to be functional, but there are contradicting data concerning the A379V polymorphism, Lp-PLA2 activity and cardiovascular disease risk. We determined the interplay between A379V SNP, Lp-PLA2 activity, and markers of oxidative stress and endothelial function with and without the effect of V279F variant. 3,220 unrelated and healthy Koreans (40-79 years) were genotyped for the Lp-PLA 2 polymorphism (A379V and V279F). Lp-PLA2 activity and markers of oxidative stress and endothelial function were measured. Lp-PLA2 activity was 3.9% higher in A/V subjects (n = 821) and 7.8% in V/V (n = 79) than in those with A/A (n = 2,320). Urinary levels of 8-epi-PGF2α were significantly lower in subjects with the A/V or the V/V genotype than in those with the A/A genotype (A/A; 1,426 ± 14, A/V; 1,371 ± 26, V/V; 1,199 ± 58 pg/mg creatinine, P = 0.003). Subjects with the 379 V/V genotype had lower serum concentrations of sICAM-1 and p-selectin compared to those with the A/A or the A/V genotype. When subjects were further stratified into subgroups based on the combination of A379V and V279F genotypes, there was no significant association between A379V genotypes and Lp-PLA2 activities in the 279 V/V group. However, the associations of the A379V SNP with levels of 8-epi-PGF2α, sICAM-1, and p-selectin remained in the subset analysis based on the V279F genotypes. This study showed a reduction in oxidative stress in subjects carrying 379V allele and the recessive effect of the A379V on the endothelial function. It is likely that the A379V polymorphism has a qualitative effect, probably by disrupting the affinity of Lp-PLA2 for platelet-activating factor substrate, towards a more anti-oxidative or anti-atherogenic form.
