Meigs, MD, MPH†# Boston and Framingham, Massachusetts; and Bethesda, Maryland Objectives We tested the association of the adipokines resistin and adiponectin with incident heart failure. Background Abnormal concentrations of adipokines may partially explain the association between obesity and heart failure. Methods We related circulating adipokine concentrations to the incidence of heart failure in 2,739 participants in the Fra- mingham Offspring Study. Results During 6 years of follow-up, 58 participants developed new-onset heart failure. In proportional hazards models (adjusting for age, sex, blood pressure, antihypertensive treatment, diabetes, smoking, total/high-density lipopro- tein cholesterol ratio, prevalent coronary heart disease, valvular heart disease, left ventricular hypertrophy, and estimated glomerular filtration rate) using the lowest third of the resistin distribution as the referent, the hazard ratios for heart failure in the middle and top thirds were 2.89 (95% confidence interval [CI]: 1.05 to 7.92) and 4.01 (95% CI: 1.52 to 10.57), respectively (p ϭ 0.004 for trend). Additional adjustment for body mass index, insulin resistance (measured with the homeostasis model), C-reactive protein, and B-type natriuretic peptide did not substantively weaken this association (multivariable hazard ratios [HRs]: 2.62 and 3.74, p ϭ 0.007). In the maximally adjusted model, each SD increment in resistin (7.45 ng/ml) was associated with a 26% increase in heart failure risk (95% CI: 1% to 60%). Concentrations of adiponectin were not associated with heart failure (multivariable HRs: 0.87 and 0.97, p ϭ 0.9). Conclusions Increased circulating concentrations of resistin were associated with incident heart failure, even after accounting for prevalent coronary heart disease, obesity, and measures of insulin resistance and inflammation. The findings suggest a role for resistin in human disease and a novel pathway to heart failure.

Attention was then turned to the possible role of the brain ANP neurons in producing natriuresis which had earlier been shown to be caused by stimulations within the anterior ventral third ventricular region (AV3V). Stimulation in this region by carbachol produced natriuresis accompanied by a dramatic increase in plasma ANP concentrations and increased content of the peptide in medial basal hypothalamus (MBH), neurohypophysis (NH) and anterior pituitary gland (AP), without alterations in the content of ANP in lungs or atria. This suggested that the natriuresis resulting from the stimulation is brought about, at least in part, by the release of ANP from the brain. Conversely, there was a dramatic decline in plasma ANP at both 24 and 128 h after AV3V lesions had been placed.

We studied the release of β-END from rat neuro-intermediate lobes of the pituitary(NIL)and from the hypothalamo-neurohypophysial complex (HNC), which consists of the hypo- thalamus, pituitary stalk, intermediate and posterior lobes of the pituitary, by means of an in vitro perifusion system. NIL and HNC were prepared from male Wistar rats and individually perifused for 30 min with perifusion medium followed by 20 min perifusion with medium containing a-rat ANP and/or dopamine (DA). Samples of perifusion medium were collected every 5 min and subjected to RIA for n-END. The basal release of ƒÀ-END from NIL was 180% of that from HNC (p<0.01), which provides further support for the presence of hypothalamic factors that inhibit (ƒÀ-END release from the intermediate pituitary. The perifusion of HNC with ANP at 10-7 and 10-6M increased the ƒÀ-END concentration by 25 and 50%, respectively (p<0.01).

    Yagmur et al. J Transl Med (2019) 17:415 https://doi.org/10.1186/s12967-019-02165-2 Journal of Translational Medicine RESEARCH Open Access Elevated MR-proANP plasma concentrations are associated with sepsis and predict mortality in critically ill patients Eray Yagmur1* , Johanna Hermine Sckaer2, Ger H. Koek3, Ralf Weiskirchen4 , Christian Trautwein2, Alexander Koch2† and Frank Tacke2,5† Abstract Background and aims: Mid-regional pro atrial natriuretic peptide (MR-proANP) is an established biomarker for heart failure, based on its key role in regulating homeostasis of water balance and blood pressure. The aim of the study was to determine the value of MR-proANP as a clinical biomarker in critical illness and/or sepsis. Upon admission to the medical intensive care unit (ICU), we investigated MR-proANP plasma concentrations in 217 critically ill patients (144 with sepsis, 73 without sepsis). Results were compared with 65 healthy controls. Results: MR-proANP plasma levels were signifcantly elevated in critically ill patients, when compared to healthy controls. Notably, MR-proANP levels were signifcantly higher in ICU patients with sepsis. MR-proANP levels were not associated with metabolic comorbidities like diabetes or obesity. In critically ill patients, MR-proANP plasma concen- trations correlated with infammatory cytokines, markers of organ dysfunction and several adipocytokines, such as resistin, retinol-binding protein 4 (RBP4) and adiponectin. Importantly, high MR-proANP plasma levels were associ- ated with mortality, as MR-proANP levels above 227.0 pmol/l indicated a particularly increased mortality risk in ICU patients. The association between MR-proANP and mortality was independent of single organ failure and infamma- tion markers.

  • Relaxin and Atrial Natriuretic Peptide Pathways Participate in the Anti-Fibrotic Effect of a Melon Concentrate in Spontaneously
    food & nutrition æ research ORIGINAL ARTICLE Relaxin and atrial natriuretic peptide pathways participate in the anti-fibrotic effect of a melon concentrate in spontaneously hypertensive rats Julie Carillon1,2, Audrey Gauthier1, Sandy Barial1, Michel Tournier1, Nathalie Gayrard1, Anne-Dominique Lajoix1 and Bernard Jover1* 1EA7288 Universite´ de Montpellier, Montpellier, France; 2Bionov Research, Montpellier, France Abstract Background: In spontaneously hypertensive rats (SHR), a model of human essential hypertension, oxidative stress is involved in the development of cardiac hypertrophy and fibrosis associated with hypertension. Dietary supplementation with agents exhibiting antioxidant properties could have abeneficial effect in remodeling of the heart. We previously demonstrated a potent anti-hypertrophic effect of a specific melon (Cucumis melo L.) concentrate with antioxidant properties in spontaneously hypertensive rats. Relaxin and atrial natriuretic peptide (ANP) were reported to reduce collagen deposition and fibrosis progression in various experimental models. Objective: The aim of the present investigation was to test the hypothesis that, beside reduction in oxidative stress, the melon concentrate may act through relaxin, its receptor (relaxin/insulin-like family peptide receptor 1, RXFP1), and ANP in SHR. Design and results: The melon concentrate, given orally during 4 days, reduced cardiomyocyte size (by 25%) and totally reversed cardiac collagen content (Sirius red staining) in SHR but not in their normotensive controls. Treatment with the melon concentrate lowered cardiac nitrotyrosine-stained area (by 45%) and increased by 17Á19% the cardiac expression (Western blot) of superoxide dismutase (SOD) and glutathione peroxidase. In addition, plasma relaxin concentration was normalized while cardiac relaxin (Western blot) was lowered in treated SHR. Cardiac relaxin receptor level determined by immunohistochemical analysis increased only in treated SHR.

  • Serum Resistin Is Associated with High Risk in Patients with Congestive Heart Failure a Novel Link Between Metabolic Signals and Heart Failure
    Circ J 2007; 71: 460–464 Serum Resistin is Associated With High Risk in Patients With Congestive Heart Failure A Novel Link Between Metabolic Signals and Heart Failure Yasuchika Takeishi, MD; Takeshi Niizeki, MD; Takanori Arimoto, MD; Naoki Nozaki, MD; Osamu Hirono, MD; Joji Nitobe, MD; Tetsu Watanabe, MD; Noriaki Takabatake, MD; Isao Kubota, MD Background Resistin is derived from fat tissue in rodents, and serum levels are elevated in animal models of obesity and insulin resistance. Recent studies have reported that resistin is correlated with markers of inflamma- tion and oxidative stress and is predictive of coronary atherosclerosis in humans. However, clinical significance of serum resistin has not been examined in heart failure. Therefore, the purpose of this study was to examine whether: (1) resistin is correlated with the severity of heart failure; and (2) resistin can predict clinical outcomes of patients with heart failure. Methods and Results Serum levels of resistin in 126 patients hospitalized for heart failure and 18 control sub- jects were measured. The patients were followed up with end-points of cardiac death and re-hospitalization caused by worsening of heart failure. The serum resistin level was higher in patients with heart failure than in control subjects and increased with advancing New York Heart Association functional class. The normal upper limit of the resistin level was determined as the mean +2standard deviation value of control subjects (14.1ng/ml). In heart failure patients, the cardiac event rate was higher in patients with a high resistin level than in those with a normal level. Among age, body mass index, serum levels of resistin, brain natriuretic peptide, loop diuretics selected by the univariate Cox regression hazard analysis, age and resistin were significant predictors of future cardiac events by multivariate Cox analysis.
