Increased nitrotyrosine plasma levels in relation to systemic markers of inflammation and myeloperoxidase in chronic heart failure

2009

The presence of a reciprocal link between inflammation and oxidative/nitrosative stress has been postulated in chronic heart failure (CHF). We aimed to determine signs of nitrosative stress in serum/plasma of CHF patients. ELISA tests were used for quantification of serum/plasma levels of Nitrotyrosine (NT), H(2)O(2), total NO, nitrite (NO(2)(-)), myeloperoxidase (MPO), Tumor Necrosis Factor-alpha (TNFalpha) and pro-Brain Natriuretic Peptide (proBNP) in 66 CHF patients (9 in NYHA I, 34 NYHA II, 23 NYHA III) and in 14 age-matched healthy subjects. NT levels were higher in NYHA III CHF patients compared to NYHA II (p<0.05), NYHA I (p<0.03) and controls (p<0.02), whereas NO(2)(-) and total NO …

Protrhombotic Effects of Contraceptives

2010

The use of oral contraceptives first became widespread some 40 years ago, and reports of an excess risk of cardiovascular disease among women who used these agents soon followed. Few drugs have been the object of such intensive epidemiological research, the outcome of which has provided clinicians with detailed information about risks not only of specific thrombotic diseases but also important non-contraceptive benefits from the pill. Recently, oral contraceptives have been classified by some according to "generation" (first, second, third, and most recently, fourth generation): first-generation formulations containing lynestrenol or norethindrone, second-generation formulations containing …

Blood Coagulation and Thrombosis in Patients with Ovarian Malignancy

1997

SummaryOvarian cancer cells appear to be capable of both thrombin formation and induction of fibrin degradation which may be essential prerequisites for the development of deep vein thrombosis (DVT) as well as the spread of malignancy. To study further this coagulation – cancer interaction in 60 patients with untreated ovarian cancer of FIGO stage I-IV the incidence of DVT was recorded pre-operatively, postoperatively on day 1, 3, 5, 7, 10, before each of six cycles of Cisplati- num/Epirubicin/Cyclophosphamide chemotherapy, during follow-up and in the post-operative period of second look surgery. In addition, blood coagulation tests results were determined prospectively. Two patients were e…

The role of fibrate treatment in dyslipidemia: an overview.

2012

Dyslipidemia, and especially atherogenic dyslipidemia, a combination of small low-density lipoproteins cholesterol (LDL-C), decreased high-density lipoprotein cholesterol (HDL-C) and increased triglyceride (TG) concentrations, represents a major cardiovascular (CV) risk factor. Nuclear receptor peroxisome proliferator-activated receptors (PPARs) are involved in the regulation of lipid metabolism; PPAR ligands are used to treat dyslipidemias. Fibrates have a major impact on TG metabolism as well as on modulating LDL size and subclasses. Fibrates target atherogenic dyslipidemia by increasing plasma HDL-C concentrations and decreasing small dense LDL (sdLDL) particles and TGs, thus contributin…

Genetic variants of ANP and cardiometabolic protection: from populations to novel therapeutics

2013

Background The cardiac hormone atrial natriuretic peptide (ANP) induces natriuresis, vasodilation and inhibits aldosterone through the activation of the guanylyl cyclase A receptor (GC-A) and the second messenger cGMP. ANP possesses also metabolic properties enhancing lipolysis and release of the adipokine adiponectin. Previous studies in general populations reported that the minor G allele of the ANP genetic variant rs5068 is associated with increased circulating levels of ANP and B-type natriuretic peptide, lower blood pressure (BP), and reduced risk of hypertension. We recently reported that in the general population from Olmsted County, MN, USA the G allele of rs5068 is associated not o…

Asthma-COPD overlap syndrome: recent advances in diagnostic criteria and prognostic significance.

2017

The term asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) has been proposed for individuals with features of both asthma and COPD. Several attempts have been done to define ACOS on the basis of medical history, symptoms, and functional findings. The main diagnostic criteria include airflow obstruction with a strong although incomplete reversibility to bronchodilation tests, a significant exposure to cigarette or biomass smoke, and a history of atopy or asthma. Additional diagnostic elements include eosinophilic airway and systemic inflammation, a good response to corticosteroid treatment, and a high concentration of exhaled nitric oxide. ACOS should be distinguish…

&lt;p&gt;Future perspectives of anticholinergics for the treatment of asthma in adults and children&lt;/p&gt;

2019

Despite major advances in therapeutic interventions and the availability of detailed treatment guidelines, a high proportion of patients with symptomatic asthma remain uncontrolled. Asthma management is largely guided by the Global Initiative for Asthma (GINA) strategy and is based on a backbone of inhaled corticosteroid (ICS) therapy with the use of additional therapies to achieve disease control. Inhaled long-acting bronchodilators alone and in combination are the preferred add-on treatment options. Although long-acting muscarinic antagonists (LAMAs) are a relatively recent addition to disease management recommendations for asthma, tiotropium has been extensively studied in a large clinic…

Prognostic value of NT-proBNP and CA125 across glomerular filtration rate categories in acute heart failure.

2021

This study aimed to evaluate whether glomerular filtration rate (eGFR) during admission modifies the predictive value of plasma amino-terminal pro-brain natriuretic peptide (NT-proBNP) and carbohydrate antigen 125 (CA125) in patients hospitalized for acute heart failure (AHF).We retrospectively evaluated 4595 patients consecutively discharged after admission for AHF at three tertiary-care hospitals from January 2008 through October 2019. To investigate the effect of kidney function on the association of NT-proBNP and CA125 with 1-year mortality (all-cause and cardiovascular mortality), we stratified patients according to four eGFR categories:30 mL•minAt 1-year follow-up, 748 of 4595 (16.3%)…

Early Spot Urinary Sodium and Diuretic Efficiency in Acute Heart Failure and Concomitant Renal Dysfunction

2020

&lt;b&gt;&lt;i&gt;Objective:&lt;/i&gt;&lt;/b&gt; In acute heart failure (AHF), early assessment of spot urinary sodium (U&lt;sub&gt;Na&lt;/sub&gt;) has emerged as a useful biomarker for risk stratification and monitoring. The objective of this study was to investigate (a) whether early spot U&lt;sub&gt;Na&lt;/sub&gt; predicts 24-h diuretic efficiency and (b) the clinical factors associated with early spot U&lt;sub&gt;Na&lt;/sub&gt; in patients with AHF and concomitant renal dysfunction (RD). &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; This is a post hoc analysis of the IMPROVE-HF trial, in which 160 patients with AHF and RD (estimated glomerular filtrate rate [eGFR] &amp;#x3c;60 mL/min/1…
