Serum biomarkers, including nitric oxide metabolites (NOx), for prognosis of cardiovascular death and acute myocardial infarction in an ESSE-RF case-control cohort with 6.5-year follow up. Sci Rep 2022; 12:18177. [PMID: 36307429 PMCID: PMC9616821 DOI: 10.1038/s41598-022-22367-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 10/13/2022] [Indexed: 12/31/2022] Open
Abstract
The present case-control study aimed to assess associations of routine and experimental biomarkers with risk for cardiovascular death and acute myocardial infarction (AMI) in a cohort recruited from the multicenter study "Cardiovascular Epidemiology in Russian Federation" (ESSE-RF) to identify experimental biomarkers potentially suitable for expanded evaluation. A total of 222 subjects included cardiovascular death (N = 48) and AMI cases (N = 63) during 6.5-year follow up and matched healthy controls. Seven routine and eight experimental biomarkers were assayed to analyze associations with outcomes using logistic and Cox proportional hazard regressions. Elevated levels of cardiac troponin I (cTnI), C-reactive protein (CRP), and nitric oxide metabolites (NOx) were independently associated (P < 0.001) with higher risk of cardiovascular death (estimated hazard ratio (eHR) = 1.83-3.74). Elevated levels of NOx and cTnI were independently (P < 0.001) associated with higher risk of nonfatal AMI (eHRs = 1.78-2.67). Elevated levels of angiopoietin-like protein 3 (ANGPTL3) were independently associated (P < 0.001) with lower risk of cardiovascular death (eHRs 0.09-0.16) and higher risk of nonfatal AMI (eHR = 2.07; P = 0.01). These results indicated that subsequent expanded validation should focus on predictive impact of cTnI, NOx, CRP, and ANGPTL3 to develop nationwide recommendations for individual stratification of patients with cardiovascular risks.

Abstract
Objective. Limited data are available regarding prognostic value of nitric oxide metabolites (NOx) for clinical hard end points. In this study, we defined optimum cut-off values of serum NOx for predicting all-cause and cardiovascular disease (CVD) mortality events and prospectively investigated their hazards in the presence of traditional risk factors. Design. Serum NOx concentrations were measured at baseline (2006-2008) and 3520 adult men and women were followed during 7.7 years for all-cause and cardiovascular disease (CVD) mortality. To determine the optimal cut-off points of serum NOx, the receiver operator characteristic (ROC) curve analysis was used. Multivariate Cox proportional hazard models were used to estimate the hazard ratios (HRs) with 95% confidence intervals (95% CIs) of all-cause and CVD mortality below and above the defined optimal cut-off points of serum NOx. Results. Mean age of participants was 44.5 ± 16.0 years at baseline and 40.2% were male. Median (inter-quartile range) of serum NOx levels was 25.0 µmol/L (19.0-37.0), at baseline. The optimal cut-off points of serum NOx levels for predicting CVD and all-cause mortality were 30.5 and 32.5 µmol/L, respectively. In the presence of age, sex, body mass index, smoking, type 2 diabetes, hypertension, and history of CVD, a significant increased risk of CVD mortality (HR = 1.98, 95% CI = 1.10-3.58) and all-cause mortality (HR = 1.52, 95% CI = 1.05-2.21) was observed for serum NOx values higher than their cut-offs. Conclusion. Serum NOx level may be predictor of CVD mortality and death, in general populations.

Abstract
Emerging data suggest that impaired nitric oxide (NO) homeostasis has a key role in development of cardiometabolic disorders. The association between circulating levels of NO metabolites, i.e. nitrate and nitrite (NOx), and risk of chronic diseases has not yet been fully clarified. This work aims to address epidemiologic aspects of NO metabolism and discusses different physiologic and pathophysiologic conditions influencing circulating NOx. Further, cross-sectional associations of serum NOx with metabolic disorders are described and along the way, potential short-term and long-term power of serum NOx for predicting cardiometabolic outcomes are reviewed. Results from population-based studies show that circulating NOx is affected by aging, smoking habits, pregnancy, menopause status, thyroid hormones, and various pathologic conditions including type 2 diabetes, insulin resistance, hypertension, and renal dysfunction. Lifestyle factors, especially dietary habits, but also smoking habits and the degree of physical activity influence NO homeostasis and the circulating levels of NOx. Elevated serum NOx, due to increased iNOS activity, is associated with increased incidence of metabolic syndrome, different obesity phenotypes, and cardiovascular events.

Abstract
We propose an optimized single-step assay of total nitrite and nitrate concentrations based on serum deproteinization by ultrafiltration. After deproteinization, the residual protein concentration was 0.0800±0.0007 mg/ml, which secured necessary transparency of the specimens in contrast to methanol deproteinization. The optimized assay for serum nitrite and nitrate ions is characterized by high reproducibility and accuracy (variation coefficient <7%) and can be recommended for routine use in clinical practice.

Abstract
Background and aim This study was conducted to investigate the association between serum nitric oxide metabolites (NOx) and the risk of chronic kidney disease (CKD). Methods We recruited 3462 and 2504 participants of the Tehran Lipid and Glucose Study (TLGS), for a cross-sectional and prospective analysis, respectively. Serum NOx concentrations were measured at baseline (2006-2008), and demographics, anthropometrics and biochemical variables were evaluated at baseline and again after 3 years (2009-2011). Estimated glomerular filtration rate (eGFR) and CKD were defined. Association between serum NOx and CKD in the cross-sectional phase and the predictability of NOx in CKD occurrence were assessed using multivariable logistic regression models with adjustment for confounders. Results Mean age of participants was 45.0 ± 15.9 years at baseline and 40.5% were male. The prevalence of CKD was 17.9% (13.4% in men, 21.0% in women) at baseline, at which point, marginally significant odds of CKD in the highest tertile of serum NOx in men (OR = 1.53, 95% CI = 0.96-2.45, p for trend = 0.047) and a significant odds of CKD in women (OR = 2.48, 95% CI = 1.76-3.49, p for trend = 0.001) were observed. After a 3-year follow-up, in women, risk of CKD was higher in the highest compared to the lowest NOx tertiles (OR = 1.86, 95% CI = 1.10-3.14, p for trend = 0.032) but no significant association was observed in men. Conclusion Serum NOx level was found to be an independent predictor of CKD in women; it could be a valuable surrogate for prediction of renal dysfunction in women and help to identify high-risk subjects.

Added value of total serum nitrate/nitrite for prediction of cardiovascular disease in middle east caucasian residents in Tehran. Nitric Oxide 2016; 54:60-6.

Abstract
Data on the association between serum nitrate/nitrite and cardiovascular disease (CVD) is controversial; the aim of this study was to examine the potential utility of serum nitrate/nitrite in prediction of CVD. A total of 2443 adult participants, free from CVD at baseline were included. The probability of developing CVD was estimated by incorporating traditional CVD risk factors into a logistic regression model in the presence of serum nitrate/nitrite. The probability of CVD was calculated using Ln-transformed CVD risk factors as a covariate in the presence of Ln-transformed nitrate/nitrite in the final model. The added value of nitrate/nitrite was estimated using receiver operating characteristic curves and the net reclassification index (NRI). During follow-up, 169 events occurred. The multivariate odds ratio (95% confidence interval) for each 1 unit of increase in the Ln-transformed traditional risk factors and Ln-transformed nitrate/nitrite, were 3.20 (2.67-3.84) and 1.35 (1.01-1.80) for incident CVD, respectively. The areas under the curves of discrimination for models with and without nitrate/nitrite were not significantly different; however, incorporating nitrate/nitrite to the traditional CVD risk model can help appropriately reclassify over 6% of individuals at risk. In conclusion, serum nitrate/nitrite levels were independently associated with incident CVD. Measurement of serum nitrate/nitrite provided information beyond individual data on risk factors and improved prediction of CVD.

Abstract
BACKGROUND Endothelial dysfunction, synonymous with reduced biological activity of nitric oxide, is related to all cardiovascular risk factors. Association between metabolic syndrome and nitric oxide metabolites (nitrite + nitrate = NO(x)) has been previously shown in cross-sectional studies. The aim of this study was to determine the ability of serum NO(x) levels in predicting the incidence of metabolic syndrome in a population-based study. METHODS Serum NO(x) levels measured in 2098 adult subjects, participants of Tehran Lipid and Glucose Study, without metabolic syndrome at baseline. After 3.3 years follow-up, logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence interval for developing metabolic syndrome, with serum NO(x) quartiles as independent variables. RESULTS Incident metabolic syndrome was diagnosed in 23.0% of men and 16.3% of women after 3.3 years. Age-adjusted risk for developing metabolic syndrome in women who had higher NO(x) values (above 75th percentile vs. lower 75th percentile) at baseline, was significantly higher [OR: 1.59 (1.11-2.27), p = 0.011]; OR remained significant after multivariable-adjustment including adjustment for components of metabolic syndrome [OR: 1.75 (1.19-2.59), p = 0.005]. Serum NO(x) could not predict the incidence of metabolic syndrome in men. CONCLUSIONS High serum NO(x) level is an independent predictor of incident metabolic syndrome in women, but not in men, a finding which presents serum NO(x) level as a potential biomarker for assessing cardiometabolic disturbances.

Abstract
AIM To evaluate the concentration of metabolites (NO(2)(-), NO(3)(-)) of nitric oxide (NO) in metabolic syndrome (MS). MATERIALS AND METHODS We enrolled 106 subjects (45 women and 61 men) with MS of which 43 (14 women and 27 men) with diabetes mellitus and 63 (31 women and 32 men) without diabetes mellitus, and 54 subjects (19 women and 35 men) as control group. The nitric oxide metabolites (nitrite+nitrate=NOx) were evaluated employing the Griess reagent. RESULTS In the whole group of MS subjects was evident, in comparison with control group, a significant increase in NOx. The same finding was also present between control group and diabetic subjects with MS and between control group and nondiabetic subjects with MS. No difference was observed between the two subgroups (diabetic and nondiabetic subjects with MS) about NOx. Contrasting information were obtained examining the linear regression among NOx, age, anthropometric profile, blood pressure values and glycometabolic pattern of subjects with MS. CONCLUSIONS In MS subjects we found a significant increase in NOx not influenced by diabetes mellitus. The NOx is a parameter that must be considered in MS keeping in mind that its behavior is related to chronic inflammation that accompanies this clinical condition.

Abstract
This study was performed to determine the risk factor pattern of the metabolic syndrome (MetS) in association with serum nitric oxide metabolites (NO(x)) in children and adolescents. The study included 851 children and adolescents, aged 4-19 years. The MetS was defined according to modified Adult treatment Panel III criteria. Cluster analysis was performed using principle components analysis with varimax orthogonal rotation to examine the risk factor pattern of the MetS. The prevalence of MetS was 10.8 and 10.0% in males and females, respectively. Age-and sex-adjusted odds ratio of having MetS was significantly higher in the upper quartile of NO(x) compared to the lower quartile (2.2, 95% CI: 1.1-4.7, p = 0.029). In the whole population, three factors were identified including blood pressure/obesity, lipid/obesity, and glucose/NO(x). Stratifying for sex, again three factors were retained; however, in males NO(x) was loaded in two factors. In conclusion, serum NO( x ) was associated and loaded with other MetS components in cluster analysis of metabolic risk factors.

Abstract
OBJECTIVES The aim of this study was to determine whether the serum nitrite plus nitrate (NO( x )) level correlates with biomarkers that are known components of the metabolic syndrome (MetS). METHODS Serum NO( x ) levels were measured using a commercial kit in 608 Japanese men and women between the ages of 39 and 85 years. Multivariate adjustments for age, smoking status, alcohol consumption and exercise were made in the analysis of covariance (ANCOVA). The components of the metabolic syndrome were defined based on the following criteria: body mass index (BMI) >/=25.0 kg/m(2), glycated hemoglobin (HbA1c) >/=5.6%, systolic blood pressure >/=130 mmHg or diastolic blood pressure >/=85 mmHg, high-density lipoprotein-cholesterol (HDL-C) </=1.03 mmol/l for men and </=1.29 mmol/l for women and triglyceride >/=1.69 mmol/l. RESULTS The logarithmically transformed age-adjusted serum NO( x ) (lnNO( x )) value was significantly higher in the low HDL-C group (1.76 +/- 0.05 mumol/l; p < 0.05) than MetS component groups (1.65 +/- 0.01 mumol/l) in men, but no difference was found in women. The means of serum lnNO( x ) after multivariate adjustment were 1.64, 1.65, 1.64, 1.66, and 1.81 mumol/l for 0, 1, 2, 3, and 4-5 MetS components for all subjects, respectively. The results of ANCOVA confirmed that the serum lnNO( x ) level was significantly correlated with the clustering of MetS components in both men and women (p < 0.0001 for trend). CONCLUSION Our results suggest that an increase in the clustering of MetS components was associated with the increase in serum NO levels in our general population.
