Prognostic Value of Asymmetric Dimethylarginine in Patients with Heart Failure: A Systematic Review and Meta-analysis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:6960107. [PMID: 32714983 PMCID: PMC7355346 DOI: 10.1155/2020/6960107] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 03/22/2020] [Accepted: 05/22/2020] [Indexed: 01/09/2023]
Abstract
Objective Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide (NO) synthesis, is reported to be a risk factor for cardiovascular disease. The purpose of the present study is to investigate whether ADMA is an independent predictor for future mortality and adverse clinical events among patients with heart failure (HF). Methods Electronic literature databases (Central, MEDLINE, and Embase) were searched for relevant observational studies on the prognostic value of ADMA in HF patients published before January 2019. Pooled hazard ratios (HRs) or odds ratio and the corresponding 95% confidence interval (CI) were calculated for risk evaluation. Results 10 studies with 2195 participants were identified and analyzed. The pooled HR of composite clinical events for the highest vs. lowest quartiles from categorical variable results was 1.34 (95% CI: 1.15-1.57, P < 0.001, I2 = 0%), which is 1.31 (95% CI: 1.10-1.55, P < 0.005, I2 = 0%) in the subgroup of acute decompensated HF. The pooled HR of composite clinical events from continuous variable results was 1.41 (95% CI: 1.21-1.63, P < 0.001, I2 = 21.9%), with 0.1 μM increment accounting for the increasing 25% risk for composite adverse clinical events. The pooled HR for all-cause mortality was 2.38 (95% CI: 1.48-3.82, P < 0.001, I2 = 0%) after sensitivity analysis. Two studies reporting the HR of inhospital mortality in HF patients regarded it as a prognostic indicator, with categorical variable HR as 1.26 (95% CI: 1.07-1.84, P < 0.05) and continuous variable OR as 2.15 (95% CI: 1.17–4.29, P < 0.05). Conclusions ADMA is an independent predictor for composite clinical outcomes among HF patients with both short-term and long-term prognostic value.

Abstract
BACKGROUND Increased asymmetrical dimethylarginine (ADMA) and NT pro-BNP concentrations have been associated with mortality in patients with cardiovascular (CV) disease and the general population. The use of these prognostic markers in an older population is not established yet. The aim of the present study was to investigate the prognostic value of age, sex, BMI, co-medication and CV laboratory risk markers in geriatric care patients. MATERIALS AND METHODS In this prospective observational single-centre cohort study data of long-term geriatric care patients were collected. Blood samples were collected between 14.09.2009 and 16.12.2009, and mortality was recorded up to 90 months. ADMA, its symmetric isomer SDMA, L-arginine, NT pro-BNP and CRP were determined at study entry. Simple associations of risk factors for survival period were explored by Spearman correlation coefficient. Significant univariate predictors for survival period were used in the Cox proportional hazard model. RESULTS A total of 481 patients were screened, and data from 449 patients were analysed. A total of 381 patients died during the observation period. Full data sets from 344 patients were used for Cox regression analysis. Male sex, older age, lower BMI, use of neuroleptic medicine, peripheral artery disease, and elevated plasma concentrations of ADMA, NT pro-BNP, and CRP were significant predictors of mortality. CONCLUSION The concentration of ADMA and NT pro-BNP may be used as an early risk marker for overall mortality in geriatric care. Neuroleptic medicine is associated with increased mortality in this population.

McCarty MF. Asymmetric Dimethylarginine Is a Well Established Mediating Risk Factor for Cardiovascular Morbidity and Mortality-Should Patients with Elevated Levels Be Supplemented with Citrulline? Healthcare (Basel) 2016; 4:healthcare4030040. [PMID: 27417628 PMCID: PMC5041041 DOI: 10.3390/healthcare4030040] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2016] [Revised: 06/21/2016] [Accepted: 06/27/2016] [Indexed: 02/07/2023] Open
Abstract
The arginine metabolite asymmetric dimethylarginine (ADMA) is a competitive inhibitor and uncoupler of endothelial nitric oxide synthase (eNOS), an enzyme that acts in multifarious ways to promote cardiovascular health. This phenomenon likely explains, at least in part, why elevated ADMA has been established as an independent risk factor for cardiovascular events, ventricular hypertrophy, and cardiovascular mortality. Fortunately, the suppressive impact of ADMA on eNOS activity can be offset by increasing intracellular arginine levels with supplemental citrulline. Although the long-term impact of supplemental citrulline on cardiovascular health in patients with elevated ADMA has not yet been studied, shorter-term clinical studies of citrulline administration demonstrate effects suggestive of increased NO synthesis, such as reductions in blood pressure and arterial stiffness, improved endothelium-dependent vasodilation, increased erection hardness, and increased ejection fractions in patients with heart failure. Supplemental citrulline could be a practical option for primary or secondary prevention of cardiovascular events and mortality, as it is inexpensive, has a mild flavor, and is well tolerated in doses (3-6 g daily) that can influence eNOS activity. Large and long-term clinical trials, targeting patients at high risk for cardiovascular events in whom ADMA is elevated, are needed to evaluate citrulline's potential for aiding cardiovascular health.

Abstract
BACKGROUND Asymmetric dimethylarginine (ADMA) inhibits the production of nitric oxide, a key regulator of the vascular tone, and may be important in the development of cardiovascular disease (CVD). Our aim was to reliably quantify the association of ADMA and its isomer symmetric dimethylarginine (SDMA) with the risk of CVD outcomes in long-term cohort studies. METHODS AND RESULTS Data were collated from 22 prospective studies involving a total of 19 842 participants, which have recorded 2339 CVD, 997 coronary heart disease, and 467 stroke outcomes during a mean follow-up of 7.1 years. In a comparison of individuals in the top with those in the bottom third of baseline ADMA values, the combined risk ratios were 1.42 (95% confidence interval: 1.29 to 1.56) for CVD, 1.39 for coronary heart disease (1.19 to 1.62), and 1.60 for stroke (1.33 to 1.91). Broadly similar results were observed according to participants' baseline disease status (risk ratios for CVD: 1.35 [1.18 to 1.54] in general populations; 1.47 [1.16 to 1.87] in individuals with pre-existing CVD; and 1.52 [1.26 to 1.84] in individuals with pre-existing kidney disease) and by different study characteristics, including geographical location, sample type, assay method, number of incident outcomes, and level of statistical adjustment (all P values>0.05). In contrast, in 8 prospective studies involving 9070 participants and 848 outcomes, the corresponding estimate for SDMA concentration was 1.32 (0.92 to 1.90) for CVD. CONCLUSIONS Available prospective studies suggest associations between circulating ADMA concentration and CVD outcomes under a broad range of circumstances. Further research is needed to better clarify these associations, particularly in large general population studies.

Abstract
OBJECTIVE We sought, for the first time, to examine the rate and predictors of hospital readmission in patients discharged after an episode of heart failure (HF) in Nigeria. METHODS This was a hospital-based, prospective, observational study that used the data from the Abeokuta HF Registry. RESULTS Overall, 1.53% (95% confidence interval [CI] 0.58-4.02) and 12.2% (95% CI 8.88-16.8) of patients were re-hospitalized at least once within 30 days and 6 months, respectively (5.3% had multiple readmissions); the latter comprised 21/138 men (15.2%) and 11/124 (8.9%) women. A total of 11 (4.2%) died (all of whom had been rehospitalized). Worsening HF (24 cases, 75%) was the commonest reason for readmission. Among others, factors associated with rehospitalization included presence of mitral regurgitation (odds ratio [OR] 2.37, 95% CI 1.26-4.46), age ≥ 60 years (OR 2.04, 95% CI 0.96-3.29), presence of tricuspid regurgitation (OR 1.77, 95% CI 0.86-3.61), and presence of atrial fibrillation (OR 1.34, 95% CI 0.59-3.03). However, on an adjusted basis, only female sex (adjusted OR 0.33, 95% CI 0.14-0.79; P = .014 vs male) and body mass index <19 kg/m² (adjusted OR 3.74, 95% CI 1.15-12.16; P = .028 vs ≥ 19 kg/m²) were independent correlates of readmission during 6 months' follow-up. CONCLUSIONS HF rehospitalization within 6 months' follow-up occurred in ∼12% of our cohort living an environment where HF etiology is predominately nonischemic and the HF population is relatively younger. Higher rates of readmission were noted in those with older age, lower body mass index, low literacy, lower serum sodium level, and presence of atrial fibrillation, renal dysfunction, and valvular dysfunction.

Abstract
The methylated arginines (MAs) monomethylarginine (MMA), asymmetric dimethylarginine (ADMA), and symmetric dimethylarginine (SDMA) have been shown to be independent predictors of cardiovascular disease. This article describes progress regarding the development of an analytical method capable of rapidly analyzing MAs using capillary electrophoresis (CE) and microchip electrophoresis (MCE) with laser-induced fluorescence (LIF) detection. Several parameters including buffer composition and separation voltage were optimized to achieve an ideal separation. The analytes of interest were derivatized with naphthalene-2,3-dicarboxaldehyde (NDA) to produce fluorescent 1-cyanobenz[f]isoindole (CBI) derivatives and then subjected to CE analysis. Baseline resolution of SDMA, ADMA, MMA, and arginine was achieved in less than 8 min. The limits of detection for SDMA, ADMA, MMA, and arginine were determined to be 15, 20, 25, and 5 nM, respectively, which are well below the expected plasma concentrations. The CE separation method was then transferred to a glass MCE device with LIF detection. MAs were baseline resolved in 3 min on-chip using a 14 cm separation channel with detection limits of approximately 10 nM for each species. To the best of the authors' knowledge, this is the first report of the separation of MAs by MCE.

Abstract
AIM Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) which plays an important role in controlling vascular tone and regulates the contractile properties of cardiac myocytes. The aim of this study was to investigate the effect of pharmacological treatment on symmetric dimethylarginine (SDMA), ADMA and arginine plasma concentrations in patients with acute congestive heart failure (ACHF) through the evaluation of type-1 system cationic amino acid transporter-1/type 1 dimethylarginine dimethylaminohydrolases-1 (CAT-1/DDAH-1). METHODS AND RESULTS 25 hospitalized cardiology patients with symptomatic acute congestive HF (NYHA Class III-IV) and impaired left ventricular (LV) function (ejection fraction<35%) were included in the study. ADMA, SDMA, and arginine plasma concentrations were assessed before and after pharmacological treatment by high performance liquid chromatography. All patients received an adequate pharmacological treatment for ACHF. ADMA and SDMA plasma levels were significantly higher after pharmacological treatment respect to baseline values (pre-treatment) (0.75 vs 0.48; 1.31 vs 1.03; p<0.01). Arginine plasma concentration was significantly lower after therapy respect to baseline values (0.78 vs 0.99; p<0.01). This is associated more with the modulation of DDAH-1 protein than with of CAT-1 system transport. CONCLUSIONS In patients with ACHF, acute renal impairment function and the modulation of metabolism and extracellular transport by the DDAH-1/CAT-1 system determine high ADMA and SDMA levels after therapy for acute congestive heart failure.

Abstract
Systemic inflammation and elevated circulating levels of the endogenous nitric oxide inhibitor asymmetrical dimethylarginine (ADMA) have been associated with increased risk in cardiogenic shock (CS). In this prospective study, we assessed, over 4 consecutive days, the changes and possible associations between vascular function, markers of inflammation, and circulating ADMA levels in patients with CS (n = 12) and postcardiotomy heart failure (n = 12, PC-HF). Vasodilator function was measured as a reactive hyperemia index (RH-index) using a finger plethysmograph. Blood samples were analyzed for plasma ADMA, interleukine-6, interleukine-8, intracellular adhesion molecule-1, and vascular adhesion molecule-1. Baseline RH-index was significantly attenuated compared with healthy controls (2.28) for both CS and PC-HF (1.35 and 1.45, respectively, P = 0.001). Although vasodilator function improved in PC-HF patients, it remained attenuated in CS. Inflammatory markers were markedly elevated followed by a significant fall during the observation period in both groups. ADMA levels increased significantly during the observation period for PC-HF, whereas no pattern of change was observed for CS. No association was found between the longitudinal changes in RH-index, markers of inflammation, or ADMA in CS. However, an improved RH-index was associated with decreasing inflammatory markers in PC-HF. ADMA correlated to arterial lactate levels and the degree of organ dysfunction in CS. In conclusion, CS and PC-HF were characterized by a marked inflammatory activation accompanied by an attenuated vasodilator function. ADMA was related to organ dysfunction and degree of hypoperfusion during CS but showed no correlations to inflammation or hampered vasodilator function. The pathogenic significance of these responses needs clarification.

Abstract
Metabolomics allows the simultaneous and relative quantification of thousands of different metabolites within a given sample using sensitive and specific methodologies such as gas or liquid chromatography coupled to mass spectrometry, typically in discovery phases of studies. Biomarkers are biological characteristics that are objectively measured and evaluated as indicators of normal biological processes, pathological processes or pharmacologic responses to a therapeutic intervention. Biomarkers are widely used in clinical practice for the diagnosis, assessment of severity and response to therapy in a number of clinical disease states. In human studies, metabolomics has been applied to define biomarkers related to prognosis or diagnosis of a disease or drug toxicity/efficacy and in doing so hopes to provide greater pathophysiological understanding of disease or therapeutic toxicity/efficacy. This review discusses the application of metabolomics in the discovery and subsequent application of biomarkers in the diagnosis and management of inborn errors of metabolism, cardiovascular disease and cancer. We critically appraise how novel biomarkers discovered through metabolomic analysis may be utilized in future clinical practice by addressing the following three fundamental questions: (1) Can the clinician measure them? (2) Do they add new information? (3) Do they help the clinician to manage patients? Although a number of novel biomarkers have been discovered through metabolomic studies of human diseases in the last decade, none have currently made the transition to routine use in clinical practice. Metabolites identified from these early studies will need to form the basis of larger, prospective, externally validated studies in clinical cohorts for their future use as biomarkers. At this stage, the absolute quantification of these biomarkers will need to be assessed epidemiologically, as will the ultimate deployment in the clinic via routine biochemistry, dip stick or similar rapid at- or near-patient care technologies.
