Abstract
Atherosclerotic cardiovascular diseases (ASCVDs) are the most common and severe public health problem nowadays. Osteopontin (OPN) is a multifunctional glycoprotein highly expressed at atherosclerotic plaque, which has emerged as a potential biomarker of ASCVDs. OPN may act as an inflammatory mediator and/or a vascular calcification (VC) mediator, contributing to atherosclerosis progression and eventual plaque destabilization. In this article, we discuss the complex role of OPN in ASCVD pathophysiology, since many in vitro and in vivo experimental data indicate that OPN contributes to macrophage activation and differentiation, monocyte infiltration, vascular smooth muscle cell (VSMC) migration and proliferation and lipid core formation within atherosclerotic plaques. Most but not all studies reported that OPN may inhibit atherosclerotic plaque calcification, making it "vulnerable". Regarding clinical evidence, serum OPN levels may become a biomarker of coronary artery disease (CAD) presence and severity. Significantly higher OPN levels have been found in patients with acute coronary syndromes than those with stable CAD. In limited studies of patients with peripheral artery disease, circulating OPN concentrations may be predictive of future major adverse cardiovascular events. Overall, the current literature search suggests the contribution of OPN to atherosclerosis development and progression, but more robust evidence is required.

Abstract
High serum uric acid (sUA) has been associated with coronary artery calcium (CAC) and increased carotid intima-media thickness (cIMT) in people at high cardiovascular risk. However, association is unclear in apparently healthy individuals. Our study aims to evaluate association between sUA and subclinical atherosclerosis measures: CAC and increased cIMT, in apparently healthy adults enrolled in ELSA-Brasil. A total of 4096 participants without previous coronary artery disease, stroke, and use of urate-lowering drugs, underwent CAC and cIMT assessment. All analyses were stratified by sex. Serum uric acid categorized by quintiles was the exposure variable. Thorough cardiovascular risk factor evaluation was performed, and association between sUA quintiles and CAC and cIMT was analyzed by linear regression using ln(CAC + 1) and cIMT, both as continuous variables. Median age of the sample was 49.0 (44.0-56.0) years (women: 55.1%; 59.1% were white). Mean values of sUA were 6.5 ± 1.4 mg/dL for men, and 4.9 ± 1.2 mg/dL for women. The highest quintile (Q5) of sUA was independently associated with cIMT in women (beta-coefficient: 0.022; 95% CI: 0.007-0.036; P = 0.003) and men (beta-coefficient: 0.020; 95% CI: 0.002-0.038; P = 0.032). Regarding CAC, no association was found: men's Q5 (beta-coefficient: -0.142; 95% CI: -0.436 to 0.153; P = 0.347) and women's Q5 (beta-coefficient: 0.046; 95% CI: -0.152 to 0.245; P = 0.647). In this cohort, the highest sUA quintiles were independently associated with cIMT in both women and men. No association was found between sUA and the presence of CAC.

[PMID: 35769144 PMCID: PMC9234354 DOI: 10.1016/j.bonr.2022.101599] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 06/07/2022] [Accepted: 06/10/2022] [Indexed: 11/25/2022] Open
Abstract
Aim To clarify the role of mediators of ectopic mineralization as biomarkers for arterial calcifications. Methods MEDLINE and Embase were searched for relevant literature, until January 4th 2022. The investigated biomarkers were: calcium, phosphate, parathyroid hormone, vitamin D, pyrophosphate, osteoprotegerin, receptor activator of nuclear factor-kappa B ligand (RANKL), fibroblast growth factor-23 (FGF-23), Klotho, osteopontin, osteocalcin, Matrix Gla protein (MGP) and its inactive forms and vitamin K. Studies solely performed in patients with kidney insufficiency or diabetes mellitus were excluded. Results After screening of 8985 articles, a total of 129 articles were included in this systematic review. For all biomarkers included in this review, the results were variable and more than half of the studies for each specific biomarker had a non-significant result. Also, the overall quality of the included studies was low, partly as a result of the mostly cross-sectional study designs. The largest body of evidence is available for phosphate, osteopontin and FGF-23, as a little over half of the studies showed a significant, positive association. Firm statements for these biomarkers cannot be drawn, as the number of studies was limited and hampered by residual confounding or had non-significant results. The associations of the other mediators of ectopic mineralization with arterial calcifications were not clear. Conclusion Associations between biomarkers of ectopic mineralization and arterial calcification are variable in the published literature. Future longitudinal studies differentiating medial and intimal calcification could add to the knowledge of biomarkers and mechanisms of arterial calcifications. We researched the association between biomarkers and arterial calcifications. This review focused on biomarkers of bone metabolism and Matrix Gla protein. Associations between biomarkers and arterial calcification are variable. Future studies should differentiate between medial and intimal calcifications.

Abstract
BACKGROUND Patients with aortic stenosis are nearly twice as likely to have a diagnosis of gout compared with individuals without aortic valve disease. METHODS This retrospective study evaluated consecutive adults age ≥65 years with aortic stenosis between December 2012 and November 2016 who underwent at least 2 transthoracic echocardiograms (TTEs) separated by at least 1 year. Severe aortic stenosis was defined as any combination of an aortic valve peak velocity ≥4.0 m/sec, mean gradient ≥40 mm Hg, aortic valve area ≤1 cm2, or decrease in left ventricular ejection fraction as a result of aortic stenosis. RESULTS Of the 699 study patients, gout was present in 73 patients (10%) and not found in 626 patients (90%). Median follow-up was 903 days [552-1302] for patients with gout and 915 days [601-1303] for patients without gout (P = 0.60). The presence of severe aortic stenosis on follow-up transthoracic echocardiogram was more frequent in patients with gout compared to those without gout (74% vs 54%, P = 0.001; hazard ratio [HR] 1.45 [1.09-1.93]), even among the 502 patients without severe aortic stenosis at baseline (63% vs 39%, P = 0.003; hazard ratio 1.43 [1.07-1.91]). Gout remained associated with the development of severe aortic stenosis after multivariable adjustment (adjusted hazard ratio [aHR] 1.46 [1.03-2.08], P = 0.03). The annualized reduction in aortic valve area was numerically greater in the group with gout compared with the group without gout (-0.10 cm2/y [-0.18, -0.03] vs -0.08 cm2/y [-0.16, -0.01], P = 0.09); annualized change in peak velocity and mean gradient did not differ between groups. CONCLUSIONS Progression to severe aortic stenosis was more frequent in patients with gout compared with those without gout, supporting the hypothesis that gout is a risk factor for aortic stenosis.

Abstract
PURPOSE to study the relationship between degree of calcification of coronary arteries, osteopenic syndrome, and clinical course of ischemic heart disease (IHD) during 3-5 years of follow-up in men after coronary artery bypass grafting (CABG). Materials and methods. We included in this prospective study 111 men admitted for CABG under cardiopulmonary bypass. All patients underwent color duplex scanning (CDS) of brachiocephalic arteries (BCA), coronary angiography, multislice computed tomography (MSCT) of coronary arteries (CAs) to assess the degree of calcification, densitometry of femoral neck. Cardiac calcium score of the vessels was assessed by the Agatston method. After 3-5 (mean 4.2) years we assessed dead or alive status of 111 patients. Mortality during followup was 11.7 % (n=13). In 59 of 98 survived patients we repeated CDS of BCA and MSCT of CAs with calculation of CA calcification scores. RESULTS Significant CA calcification prior to CABG was detected in more than half of the patients (57.6 %). Among all clinical and anamnestic factors only one risk factor - smoking was associated with mortality (odds ratio [OR] 9.8, 95 % confidence interval [CI] 1.2-78.1, χ2=6.6, р=0.01). There were no association of mortality with index of CA calcification, Syntax score, osteopenic syndrome and BCA involvement. In the group of patients with baseline coronary calcification index >400 there were more smokers (р=0.026) and patients with lesions in >3 CAs (р=0.037) compared with the group with values ≤400. At the preoperative stage we revealed associations of CAs calcification index with T-test characterizing presence of the osteopenic syndrome (r= -0.24, р=0.06), Syntax score (r=0.26, р=0.041), and number of affected CAs (r=0.25, р=0.048). At repeated examination 3-5 years after CABG a medium positive correlation was detected between the severity of CA calcification and the severity of BCA stenoses (r=0.28, р=0.029). Linear regression analysis with stepwise selection identified baseline (prior to CABG) higher values of T-test evaluated at femoral bone as the only significant predictor of calcium score increase during 3-5 years of follow-up. CONCLUSION Dynamics of calcification of CAs in men with IHD during 3-5 years of follow-up after CABG was multidirectional, but in most cases (66 %) it was progressive. There was correlation between coronary calcification and smoking status and decreased T-test assessed at femoral bone prior to CABG. In the long-term follow-up period the correlation between severity of BCA lesion and severity of coronary calcification was found. Negative correlation was detected between progression of coronary calcification and baseline impairment of mineral density of femoral bone.

Abstract
Biological markers have served for diagnosis, risk stratification and guided therapy of heart failure (HF). Our knowledge regarding abilities of biomarkers to relate to several pathways of HF pathogenesis and reflect clinical worsening or improvement in the disease is steadily expanding. Although there are numerous clinical guidelines, which clearly diagnosis, prevention and evidence-based treatment of HF, a strategy regarding exclusion of HF, as well as risk stratification of HF, nature evolution of disease is not well established and requires more development. The aim of the chapter is to discuss a role of biomarker-based approaches for more accurate diagnosis, in-depth risk stratification and individual targeting in treatment of patients with HF.

Abstract
BACKGROUND An independent association between gout and coronary artery disease is well established. The relationship between gout and valvular heart disease, however, is unclear. The aim of this study was to assess the association between gout and aortic stenosis. METHODS We performed a retrospective case-control study. Aortic stenosis cases were identified through a review of outpatient transthoracic echocardiography (TTE) reports. Age-matched controls were randomly selected from patients who had undergone TTE and did not have aortic stenosis. Charts were reviewed to identify diagnoses of gout and the earliest dates of gout and aortic stenosis diagnosis. RESULTS Among 1085 patients who underwent TTE, 112 aortic stenosis cases were identified. Cases and nonaortic stenosis controls (n = 224) were similar in age and cardiovascular comorbidities. A history of gout was present in 21.4% (n = 24) of aortic stenosis subjects compared with 12.5% (n = 28) of controls (unadjusted odds ratio 1.90, 95% confidence interval 1.05-3.48, P = .038). Multivariate analysis retained significance only for gout (adjusted odds ratio 2.08, 95% confidence interval 1.00-4.32, P = .049). Among subjects with aortic stenosis and gout, gout diagnosis preceded aortic stenosis diagnosis by 5.8 ± 1.6 years. The age at onset of aortic stenosis was similar among patients with and without gout (78.7 ± 1.8 vs 75.8 ± 1.0 years old, P = .16). CONCLUSIONS Aortic stenosis patients had a markedly higher prevalence of precedent gout than age-matched controls. Whether gout is a marker of, or a risk factor for, the development of aortic stenosis remains uncertain. Studies investigating the potential role of gout in the pathophysiology of aortic stenosis are warranted and could have therapeutic implications.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a widely prevalent hepatic disorder that covers wide spectrum of liver pathology. NAFLD is strongly associated with liver inflammation, metabolic hyperlipidaemia and insulin resistance. Frequently, NAFLD has been considered as the hepatic manifestation of metabolic syndrome. The pathophysiology of NAFLD has not been fully elucidated. Some patients can remain in the stage of simple steatosis, which generally is a benign condition; whereas others can develop liver inflammation and progress into non-alcoholic steatohepatitis, fibrosis, cirrhosis and hepatocellular carcinoma. The mechanism behind the progression is still not fully understood. Much ongoing proteomic researches have focused on discovering the unbiased circulating biochemical markers to allow early detection and treatment of NAFLD. Comprehensive genomic studies have also begun to provide new insights into the gene polymorphism to understand patient-disease variations. Therefore, NAFLD is considered a complex and mutifactorial disease phenotype resulting from environmental exposures acting on a susceptible polygenic background. This paper reviewed the current status of proteomic and genomic studies that have contributed to the understanding of NAFLD pathogenesis. For proteomics section, this review highlighted functional proteins that involved in: (1) transportation; (2) metabolic pathway; (3) acute phase reaction; (4) anti-inflammatory; (5) extracellular matrix; and (6) immune system. In the genomic studies, this review will discuss genes which involved in: (1) lipolysis; (2) adipokines; and (3) cytokines production.

Abstract
BACKGROUND Serum uric acid (SUA) elevation has been associated with the main determinants of atherosclerosis and metabolic syndrome, although an independent relationship between SUA and coronary artery disease (CAD) has never been confirmed. Recent reports suggested a central role of SUA in diabetic patients, possibly being an early marker of impaired glucose metabolism and best predicting the risk of cardiovascular events in these patients. Aim of current study was to evaluate the relationship between diabetes and uric acid and its association with the extent of CAD and platelet aggregation among diabetics. METHODS In diabetic patients undergoing coronary angiography, fasting samples were collected for uric acid levels assessment. Coronary disease was defined for at least 1 vessel stenosis>50% as evaluated by QCA. RESULTS Diabetes was observed in 1173 out of 3280 (35.7%) diabetes was related to age, hypercholesterolemia, hypertension, BMI, renal failure, previous MI or coronary revascularization (p<0.001, respectively) and smoking (p=0.001). Diabetics were more frequently treated with ACE-inhibitors, ARBs, b-blockers, calcium-antagonists, diuretics, statins (p<0.001, respectively), and ASA (p=0.004). Diabetics displayed higher glycemia and HbA1c (p<0.001), higher creatinine and triglycerides (p<0.001) but lower total and HDL cholesterol (p<0.001) and haemoglobin (p<0.001). No significant difference was found in SUA levels between diabetic and non diabetic patients (p=0.09). In fact, we identified age, renal failure, hypertension, smoking, BMI, use of diuretics, statins, haemoglobin, triglycerides and HDL cholesterol levels as independent predictors of higher levels of uric acid (3rd tertile,≥6.7mg/dl or 0.39mmol/l). Among diabetic patients, no relationship was found between uric acid and the extent of coronary artery disease (p=0.27; adjusted OR [95%CI]=0.93 [0.76-1.1], p=0.48), or severe (LM-trivessel) CAD (P=0.05; adjusted OR [95%CI]=1.01 [0.86-1.18], p=0.94). Furthermore, SUA levels did not influence platelet aggregation. CONCLUSION Ageing, BMI, renal failure, hypertension, smoking, use of statins and diuretics, haemoglobin, HDL cholesterol and tryglicerides levels but not diabetes or glycemic control are independent predictors of hyperuricemia. Among diabetic patients, higher SUA is not independently associated with the extent of CAD or with platelet aggregation.

Usefulness of multidetector row computed tomography for predicting cardiac events in asymptomatic chronic kidney disease patients at the initiation of renal replacement therapy. ScientificWorldJournal 2013; 2013:916354. [PMID: 24363626 PMCID: PMC3864147 DOI: 10.1155/2013/916354] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2013] [Accepted: 10/28/2013] [Indexed: 11/23/2022] Open
Abstract
Background. The prevalence of coronary artery stenosis (CAS) at the initiation of renal replacement therapy (RRT) in chronic kidney disease (CKD) patients has not been fully elucidated. Although coronary angiography is the gold standard in diagnosing CAS its invasiveness and economic burden lead to searching for a noninvasive alternative method. In this study, we evaluated the prevalence of CAS by multidetector row computed tomography (MDCT) and related risk factor to articulate the usefulness of MDCT. Method. Seventy-four asymptomatic CKD patients who began dialysis were evaluated with echocardiography and MDCT. The patients were stratified into two groups according to CAS and coronary artery calcification score (CACS) by MDCT to detect silent CAS and evaluate its predictability for cardiac events. Results. CAS was seen in 24 (32.4%) of 74 asymptomatic CKD patients on MDCT. Both groups showed increasing frequencies of CAS with age (P < 0.01), presence of diabetes (P < 0.05), uric acid level (P < 0.01), and calcium score (P < 0.01). Multiple regression analysis revealed that age and uric acid level were independent risk factors for CAS and high CACS in asymptomatic CKD patients at the initiation of dialysis. Patients with both CAS and high CACS were presented with higher cardiac events rates compared to those without any of them. In Cox regression model, age and the presence of CAS and high CACS on MDCT were an independent risk factor for cardiac events in these patients. Conclusion. We showed that CAS was highly seen in asymptomatic CKD patients starting dialysis. Moreover, both high CACS and CAS on MDCT might predict cardiac events in these patients and MDCT can be a useful screening tool for evaluating coronary artery disease and predicting cardiovascular mortality noninvasively.
