Plasma Renin Concentration is Associated With Hemodynamic Deficiency and Adverse Renal Outcome in Septic Shock.
International audience; Background: In septic shock, both systemic vasodilatation and glomerular arteriole dilatation are responsible for the drop in glomerular filtration observed in early acute kidney injury. Angiotensin II has been showed to act on both mechanisms. Our objective was to evaluate the impact of renin angiotensin system activation, on hemodynamic deficiency and renal outcome in patient with septic shock and to assess whether urinary sodium could be a reliable test for high plasma renin concentration screening.Methods: This was a prospective and observational study. Inclusion criteria were 1) early septic shock (first episode) 2) dose of norepinephrine ≥ 0.25 μg/kg/min 3) bef…
O29 Diminution du contenu en sphingosine-1-phosphate dans les lipoprotéines de haute densité (HDL) au cours du diabète de type 1
Introduction La fonctionnalite des HDL des patients diabetiques de type 1 (DT1) est alteree. Ces anomalies sont en partie attribuables a des modifications glycoxydatives mais pourraient egalement s'expliquer par des variations de la composition en phospholipides et sphingolipides a la surface des HDL, molecules qui jouent un role important dans les differentes fonctions des HDL. Patients et methodes Nous avons recrute 43 patients DT1 (âge : 44,3±16,1 ; 17 hommes, 19 femmes) et 36 sujets controles normolipidemiques (âge : 40,3±14,6 ; 18 hommes, 25 femmes). Nous avons etabli la composition en phospholipides et sphingolipides des HDL par chromatographie liquide couplee a la spectrometrie de ma…
Liver Fat Content in People with Pituitary Diseases: Influence of Serum IGF1 Levels
AbstractNon-alcoholic fatty liver disease (NAFLD) is commonly associated with obesity, metabolic syndrome, and type 2 diabetes. NAFLD is also seen in patients with endocrinopathies. However, the relationship between endocrine diseases and the development of NAFLD is not well known. In this study, we set out to determine whether liver fat content (LFC) was associated with IGF1 levels in people with pituitary diseases (PD). Eighty-nine patients with pituitary diseases and 74 healthy controls were included in this study. LFC was measured using MRI. Hepatic steatosis was defined as LFC>5.5%. Patients with PD were older, and had a higher BMI than healthy controls. LFC was significantly higher…

Specific enrichment of 2-arachidonoyl-lysophosphatidylcholine in carotid atheroma plaque from type 2 diabetic patients
IF 3.942; International audience; Background and aims: Diabetic patients are at high risk of stroke and coronary artery disease. Recent data suggest that arachidonic acid metabolism is altered in diabetic conditions and that these alterations contribute to accelerated atherosclerosis. Little is known about how these alterations affect the metabolism and the proportions of different lipid species within the atherosclerotic plaque. The aim of our study was to perform a targeted lipidomic analysis of human atherosclerotic lesions, with a specific focus on PUFA-containing lipid species, to reveal differences in the fatty-acid composition of plaque in diabetic patients compared with non-diabetic…
CO-74: Altérations majeures du sphingophospholipidome des lipoprotéines de haute densité (HDL) de patients avec syndrome métabolique et glycémie normale
Rationnel Les phospholipides et sphingolipides jouent un role primordial dans la fonctionnalite et le role anti-atherogene des HDL. Ces proprietes sont alterees chez les patients porteurs d'un syndrome metabolique avant meme l'apparition d'une hyperglycemie. Nous avons donc recherche si les HDL de ces patients presentaient des anomalies de leur sphingophospholipidome. Patients et Methodes Par chromatographie liquide couplee a la spectrometrie de masse en tandem, nous avons quantifie 80 especes moleculaires des principales classes de phospholipides et sphingolipides des HDL2 et HDL3, chez 26 patients avec un syndrome metabolique et une glycemie a jeun nor-male (14 hommes, 12 femmes, âge moye…
