2 Developed in collaboration with the Heart Failure Association of the ESC (HFA) and endorsed by the European Society of Intensive Care Medicine (ESICM). In a study of laboratory mice with failing hearts caused by mutant alpha B-Crystallin, Benjamin and several U of U colleagues found increased activity of the biochemical pathway leading to high levels of reduced glutathione in the animals. Publishing in Cell 130, 427--439, August 10, 2007. An official website of the United States government. Fig. In conclusion, although further studies are needed to verify the diagnostic and/ or predictive value of blood glutathione in heart failure as a part of a multi marker panel test, this study provides evidence that cardiac and systemic glutathione deficiency is related with the functional status and the structural cardiac abnormalities of patients with cardiac diseases. Blood glutathione deficiency worsens in patients of NYHA class II to IV in relation to blood sTNFR1 elevation, a marker of heart failure. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. It should be mentioned that the present study is limited by the relatively small cohort size. Interestingly, significant depletion in blood glutathione occurred before detectable elevation in blood sTNFR1. One may also note that deficiency in systemic glutathione in cardiac patients occurs well before the drop in cardiac tissue glutathione. Several studies provide evidence for a close relationship between blood glutathione decrease and the pathogenesis of different inflammatory chronic diseases [22], [32]. 1B *P<0.05 vs NYHA class I. The cohort displayed standard relations between functional NYHA class and LVEF (A) or blood sTNFR1 level (B).

In short, it is a spectrophotometric/microplate reader assay method, relying on oxidation of reduced glutathione (GSH) by the sulfhydryl reagent 5,5-dithio-bis(2-nitrobenzoic acid) (DTNB) to form the yellow derivative 5-thio-2-nitrobenzoic acid (TNB), measurable at 405 nm.

Secondly, glutathione content in the atrial tissue is diminished by 58% in NYHA class IV patients compared to NYHA class I patients, and the degree of its decrease in CAD patients correlates with LVEF decline. ). Fig. Franco R, Schoneveld OJ, Pappa A, Panayiotidis MI. ). Patients with CAD and patients with dilated cardiomyopathy had reduced LVEF while AS patients displayed significant hypertrophy of septal (ST) and posterior (PWT) end-diastolic walls but preserved LVEF ( Inflammatory mediators and the failing heart. Fig. Compared to patients of NYHA class I, patients of NYHA class II to IV displayed larger depletion in blood glutathione (P=0.005) with a mean 40% decrease below the control value (P<0.0001). Atrial tissue samples were cut into 20 m sections. Fig. The tripeptide glutathione (L-gamma-glutamyl-cysteinyl-glycine) is essential to cell survival, and deficiency in cardiac and systemic glutathione relates to heart failure progression and cardiac remodelling in animal models. A recent study released by the Journal of Nutritional Biochemistry has taken our understanding of grapes & heart failure prevention further: its all about the glutathione. By lowering the levels of reduced glutathione without the altering mutant gene encoding thee alpha B-Crystallin, , the study shows reductive stress can be addressed through new drugs that target the genetic pathway causing the problem, according to Benjamin.

Selenium, too, is necessary for activation of the antioxidant. In fact, systemic glutathione provides many tissues in the body, and its deficiency is likely to affect vital functions including resistance to oxidative stress, mitochondrial function and integrity, immune response and cell survival [33]. The site is secure. Grapes turn on antioxidant defense pathways that lead to higher blood levels of this vital antioxidant. National Library of Medicine Glutathione was measured using standard enzymatic recycling method in venous blood samples obtained from 91 individuals, including 15 healthy volunteers and 76 patients of New York Heart Association (NYHA) functional class I to IV, undergoing cardiac surgery for coronary artery disease, aortic stenosis or terminal cardiomyopathy. In contrast, patients of NYHA class IV demonstrated a dramatic 58% depletion in atrial tissue glutathione, dropping to 1.00.2 nmol glutathione/mg tissue to be compared to 2.40.2 nmol glutathione/mg tissue in NYHA class I patients (P=0.002) ( To establish the connection between reduced glutathione and heart failure, Benjamin mated mutant alpha B-Crystallin mice that carried too much G6PD with mice that had far lower levels.
