Immune-unreactive urinary albumin as a predictor of cardiovascular events: The Hortega Study

2019

Background: We aimed to determine if immune-unreactive albumin excretion (IURAE) is associated with cardiovascular (CV) events in a representative sample of a general population from Spain.Methods: We included 1297 subjects (mean age ± standard error 48.0 ± 0.2 years, 48% females), who participated in the Hortega Follow-Up Study. The primary endpoint was incidence of fatal and non-fatal CV events. Urinary albumin excretion (UAE) was measured in spot voided urine, frozen at -80°C, by immunonephelometry [immune-reactive albumin excretion (IRAE)] and by high-performance liquid chromatography (HPLC) [total albumin excretion (AE)]. IURAE was calculated as the difference between HPLC measurements…

A call to action and a lifecourse strategy to address the global burden of raised blood pressure on current and future generations ; The Lancet Commi…

2016

Elevated blood pressure is the strongest modifiable risk factor for cardiovascular disease worldwide. Despite extensive knowledge about ways to prevent as well as to treat hypertension, the global incidence and prevalence of hypertension and, more importantly, its cardiovascular complications are not reduced—partly because of inadequacies in prevention, diagnosis, and control of the disorder in an ageing world. The aim of the Lancet Commission on hypertension is to identify key actions to improve the management of blood pressure both at the population and the individual level, and to generate a campaign to adopt the suggested actions at national levels to reduce the impact of elevated blood…

THE METABOLIC SYNDROME IN HYPERTENSION

2019

The metabolic syndrome (MS) is currently considered to be a cluster of metabolic and cardiovascular risk factors including blood pressure elevation. A higher risk to develop hypertension in MS subjects with high-normal blood pressure has been observed and, when hypertension is established, seems to be what confers a higher cardiovascular risk on top of the risk induced by blood pressure elevation. Therefore, assessment of MS components can result in clinical utility strategy to manage hypertension based on individual risk. The main mechanisms for blood pressure elevation include overactivity of the sympathetic and the reninangiotensin system, abnormal renal sodium handling, and endothelial …

Genetic bases of urinary albumin excretion and related traits in hypertension

2010

Epidemiological as well as animal studies have recognized the potential role of genetic factors in the development of microalbuminuria and related traits (renal insufficiency, end-stage renal disease and nephroangiosclerosis) in hypertension. To unravel genetic variants of susceptibility, candidate gene, linkage and genome wide scan analysis has been used. In spite of the great efforts that have been made in the field, sound knowledge about the major genetic variants causing the susceptibility to develop renal damage in hypertension is scarce, since many associations were not replicated or only showed association in a certain subgroup of patients. Looking initially at genes of the most impo…

Urinary exosome miR-146a is a potential marker of albuminuria in essential hypertension

2018

Abstract Background There is increasing interest in using extracellular vesicle-derived microRNAs (miRNAs) as biomarkers in renal dysfunction and injury. Preliminary evidence indicates that miRNAs regulate the progression of glomerular disease. Indeed, exosomes from the renal system have provided novel evidence in the clinical setting of albuminuria. Thus, the aim of this study was to quantify the urinary miRNAs present in exosome and microvesicles (MVs), and to assess their association with the presence of increased urinary albumin excretion in essential hypertension. Methods Exosomes were collected from urine specimens from a cohort of hypertensive patients with (n = 24) or without albumi…

Glomerular Filtration Rate in Renal Damage

2015

Renal function is mainly represented by the glomerular filtration (GF), which is dependent on the number and function of the nephrons. Glomerular filtration declines progressively after the third decade with a progressive loss of 1 % per year. In addition to diseases producing direct damage in the glomerular structures, high blood pressure values, diabetes, and dyslipidemia are the main factors increasing the rate of GF decline over the years. Other functional parameters of the kidney such as renal plasma flow or tubular functions are not measured in daily practice in hypertension and are not related to risk for cardiovascular disease (CVD).

Special Considerations for Antihypertensive Agents in Dialysis Patients

2010

Hypertension is present in most patients with end-stage renal disease and likely contributes to the premature cardiovascular disease in dialysis patients. Previous practice guidelines have recommended that, in patients on chronic dialysis, blood pressure (BP) should be reduced below 130/80 mm Hg. This is based on opinions but not strong evidence, since no concrete information exists about which BP values should be the parameter to follow and which should be the target BP values. The majority of the antihypertensive agents can be used in this population, but the pharmacokinetics altered by the impaired kidney function and dialyzability influence the appropriate dosage as well as the time and…

24-hour Ambulatory BP Monitoring and Home BP Measurements in Resistant Hypertension

2013

Out-of-office BP measurements, ambulatory BP monitoring (ABPM), and self-BP measurement play an important role in the evaluation of resistant hypertension. In fact 24 h ABPM has been considered mandatory at the time to evaluate resistant hypertension from the beginning of clinical use. Furthermore, clinical research has expanded the potential role of out-of-office measurements not only to the initial evaluation of resistant hypertension but also to refine cardiovascular and renal risk stratification and for a better follow-up. The widespread use of self-BP measurement at home introduced a new tool to properly assess out-of-office BP, and it has also been recommended in these patients althou…

Defects in plant immunity modulate the rates and patterns of RNA virus evolution

2020

AbstractIt is assumed that host genetic variability for susceptibility to infection necessarily conditions virus evolution. Differences in host susceptibility can either drive the virus to diversify into strains that track different defense alleles (e.g., antigenic diversity) or to infect only the most susceptible genotypes. To clarify these processes and their effect on virulence, we have studied how variability in host defense responses determine the evolutionary fate of viruses. To accomplish this, we performed evolution experiments with Turnip mosaic potyvirus in Arabidopsis thaliana mutants. Mutant plants had disruptions in infection-response signaling pathways or in genes whose produc…

Proteinuria-Microalbuminuria in Renal Damage

2015

Proteinuria (P) usually results from an insult in the glomerular and/or tubular structures of the kidney. It has been considered a marker of risk not only to develop renal insufficiency but also to suffer cardiovascular events, based on prospective studies carried out in the general population as well as in diabetic and hypertensive patients [1]. In fact, proteinuria has been considered a strong marker of risk and an intermediate endpoint during treatment [2, 3].

Cost Reduction in Irrigation Networks by an Efficient Use of Pressure Reducing Valves

1992

The cost effective design of hydraulic networks has been traditionally studied from the point of view of the relationship between hydraulic variables and economic parameters, with piping being the main element studied. The reason is clear: the piping is by far the most costly item of a projected network. However it is not usual to find an explicit consideration of the influence that pipe thickness has on the cost of the network because of the added difficulty that this aspect poses to formulating the problem of optimization. In irrigation networks, which are typically branched, it is advisable to place Pressure Reducing Valves (PRV’s) to fulfil three main goals: 1) to control the flow rate …

Other Methods to Assess Renal Damage

2015

Although glomerular filtration rate (GFR) and proteinuria remain gold standard in the evaluation of renal target organ damage, imaging techniques and image-derived parameters allow for both assessment of renal function and estimation of cardiovascular risk. Enhancement in digital image processing permits dynamic measurement of renal vascular and intraparenchymal processes in real time. The most relevant in terms of clinical use to assess hypertension-induced organ damage are the renal resistive index (RRI), renal calcium score, and functional magnetic resonance imaging.

Polymorphisms of the UCP2 gene are associated with body fat distribution and risk of abdominal obesity in Spanish population

2011

Eur J Clin Invest 2011 Abstract Background  Increased accumulation of fat results from an imbalance between energy expenditure and intake, being modulated by different environmental and genetic factors. Uncoupling proteins (UCPs) are mitochondrial carrier proteins able to spend energy generating heat. Therefore, variations in these genes are good candidates as potential modulators of body fat accumulation. Our aim was to investigate the possible association of genetic variations of the gene codifying the UCP2 protein with obesity and fat distribution. Design  We performed a cross-sectional study in 2367 individuals from two population-based studies from different regions of Spain. The Horte…

Different impacts of cardiovascular risk factors on oxidative stress.

2011

The objective of the study was to evaluate oxidative stress (OS) status in subjects with different cardiovascular risk factors. With this in mind, we have studied three models of high cardiovascular risk: hypertension (HT) with and without metabolic syndrome, familial hypercholesterolemia (FH) and familial combined hyperlipidemia (FCH) with and without insulin resistance. Oxidative stress markers (oxidized/reduced glutathione ratio, 8-oxo-deoxyguanosine and malondialdehide) together with the activity of antioxidant enzyme triad (superoxide dismutase, catalase, glutathione peroxidase) and activation of both pro-oxidant enzyme (NAPDH oxidase components) and AGTR1 genes, as well as antioxidant…

Evolution of Trans‐ fatty acid consumption in Thailand and strategies for its reduction

2020

Eliminating industrially produced trans-fatty acids (TFAs) from the food supply is one of the World Health Organization's (WHO's) priority targets to control and prevent non-communicable diseases. This review paper describes the strategies used to reduce TFA consumption in Thailand based on a situation analysis consisting of an assessment of TFA content in the national food supply, its intake, and stakeholder-based analysis of Strengths, Weaknesses, Opportunities, and Threats (SWOT). The analysis resulted in the drafting of a regulatory approach, which was then considered by stakeholders. Bakery products containing partially hydrogenated oils (PHOs) are the major sources of TFAs in Thailand…

Ambulatory Blood Pressure in Clinical Practice: Clinical Relevance of Circadian Rhythm and Nocturnal Dip

2012

Blood pressure (BP) variability and terms like dipper and nondipper are now common in daily practice. Several mechanisms underlie abnormalities in circadian variability. Sympathetic overactivity, reduced sensibility of baroreceptors, volume overload, and primary or secondary autonomic dysfunction are the most important factors related to abnormalities in circadian variability. The level of nighttime BP drop has been related to the absolute level of BP elevation, the global cardiovascular risk, the presence of comorbidities, and the type and time of administration of antihypertensive treatment. The relative importance of circadian variability or nocturnal BP as a prognostic factor raise not …

Miliary tuberculosis infection during hepatitis C treatment with sofosbuvir and ledipasvir plus ribavirin

2017

Chronic hepatitis C virus (HCV) infection is one of the main causes of chronic liver disease worldwide. In the last 5 years, treatment for HCV infection has experienced a marked development. In 2014, the use of ledipasvir/sofosbuvir with or without concomitant weight-based ribavirin was approved with a very significant increase in the sustained virological response. However, new side effects have been associated. We report the first case of an HCV infected patient treated for 12 wk with the combination of sofosbuvir/ledipasvir plus ribavirin who developed a miliary tuberculosis (TB) infection while on therapy. The patient was a 65-year-old woman, who referred malaise, asthenia, hyporexia, 7…

Urinary- and Plasma-Derived Exosomes Reveal a Distinct MicroRNA Signature Associated With Albuminuria in Hypertension.

2021

Urinary albumin excretion (UAE) is a marker of cardiovascular risk and renal damage in hypertension. MicroRNAs (miRNAs) packaged into exosomes function as paracrine effectors in cell communication and the kidney is not exempt. This study aimed to state an exosomal miRNA profile/signature associated to hypertension with increased UAE and the impact of profibrotic TGF-β1 (transforming growth factor β1) on exosomes miRNA release. Therefore, exosomes samples from patients with hypertension with/without UAE were isolated and characterized. Three individual and unique small RNA libraries from each subject were prepared (total plasma, urinary, and plasma-derived exosomes) for next-generation sequ…

Association of a Mineralocorticoid Receptor Gene Polymorphism With Hypertension in a Spanish Population

2009

BACKGROUND To assess the association of polymorphisms and haplotypes of the mineralocorticoid receptor (MR) (NR3C2) gene to the risk of essential hypertension (HTN) in a Spanish population. METHODS This is a population-based study which included 1,502 subjects (748 women) >18 years old. Twenty-four polymorphisms of NR3C2 gene were analyzed by using SNPlex (Genotyping System based on OLA/PCR technology). RESULTS Alleles of the single-nucleotide polymorphism (SNP) rs5522 were significantly associated with the risk of HTN, both in the recessive and codominant models adjusted by age, gender, and body mass index (BMI). Genotype GG of the rs5522 showed to be protective against HTN odds ratio (OR)…

Impact of Obesity in Kidney Diseases.

2021

The clinical consequences of obesity on the kidneys, with or without metabolic abnormalities, involve both renal function and structures. The mechanisms linking obesity and renal damage are well understood, including several effector mechanisms with interconnected pathways. Higher prevalence of urinary albumin excretion, sub-nephrotic syndrome, nephrolithiasis, increased risk of developing CKD, and progression to ESKD have been identified as being associated with obesity and having a relevant clinical impact. Moreover, renal replacement therapy and kidney transplantation are also influenced by obesity. Losing weight is key in limiting the impact that obesity produces on the kidneys by reduc…

Association of central and peripheral pulse pressure with intermediate cardiovascular phenoytpes

2012

Objective: We assessed the relationship between pulse pressure and intermediate cardiovascular phenotypes in a middle-aged cohort with high prevalence of hypertension. Background: It has been suggested that central pulse pressure (cPP) is a better predictor of cardiovascular outcome than peripheral pulse pressure (pPP), particularly in the elderly. Yet, it is unclear if cPP provides additional prognostic information to pPP in younger individuals. Methods: In 535 individuals we assessed cPP and pPP as well as the intermediate cardiovascular phenotypes pulse wave velocity (PWV; SphygmoCor, Complior, PulsePen), carotid intima-media thickness (C-IMT; carotid ultrasound), left-ventricular mass i…
