OBJECTIVES This study investigated the effect of bariatric surgery (BS)-induced weight loss on cardiac ectopic fat using 3T magnetic resonance imaging in morbid obesity. BACKGROUND Heart disease is one of the leading causes of mortality and morbidity in obese patients. Deposition of cardiac ectopic fat has been related to increased heart risk. Whether sustained weight loss can modulate epicardial fat or myocardial fat is unknown. METHODS Twenty-three morbidly obese patients underwent 1H-magnetic resonance spectroscopy to determine myocardial triglyceride content (MTGC), magnetic resonance imaging to assess epicardial fat volume (EFV), cardiac function, and computed tomography visceral abdominal fat (VAF) measurements at baseline and 6 months after BS. RESULTS The BS reduced body mass index significantly, from 43.1±4.5 kg/m2 to 32.3±4.0 kg/m2, subcutaneous fat from 649±162 cm2 to 442±127 cm2, VAF from 190±83 cm2 to 107±44 cm2, and EFV from 137±37 ml to 98±25 ml (all p<0.0001). There was no significant change in MTGC: 1.03±0.2% versus 1.1±0.2% (p=0.85). A significant reduction in left ventricular mass (118±24 g vs. 101±18 g) and cardiac output (7.1±1.6 l/min vs. 5.4±1.0 l/min) was observed and was statistically associated with weight loss (p<0.05). The loss in EFV was limited (-27±11%) compared to VAF diminution (-40±19%). The EFV variation was not correlated with percentage of body mass index or VAF loss (p=0.007). The ratio of %EFV to %VAF loss decreased with sleep apnea syndrome (1.34±0.3 vs. 0.52±0.08, p<0.05). CONCLUSIONS Six-month BS modulates differently cardiac ectopic fat deposition, with a significant decrease in epicardial fat and no change in myocardial fat. Epicardial fat volume loss was limited in patients with sleep apnea. (Impact of Bariatric Surgery on Epicardial Adipose Tissue and on Myocardial Function; NCT01284816).

Intrauterine growth retardation (IUGR) is associated with increased prevalence, at the adult age, of central obesity, the metabolic syndrome, and its complications (type 2 diabetes and coronary heart disease). Programming of the corticotropic function is one of the mechanisms underlying the above-mentioned phenomenon. An increased passage of active glucocorticoids from the mother to the fetus can act, at the central nervous system level, to program an enhanced response to stress and, at the peripheral level, in adipose tissue to induce an increased local glucocorticoid exposure and sensitivity. In addition to an improvement of the health of pregnant women, early diagnosis of metabolic and hormonal disturbances is important in children with IUGR, in order to prevent a compensatory catch-up growth and its subsequent obesity, and to set up a therapeutic intervention against the deleterious consequences of hypercorticism.

Points essentiels Le surpoids et l’obesite correspondent a un exces de masse grasse, defini et evalue, en pratique clinique, par l’indice de masse corporelle (IMC – rapport du poids, en kilogrammes, sur le carre de la taille, en metre). Les consequences de l’obesite sur la sante sont nombreuses: complications metaboliques, cardiovasculaires et mecaniques, predisposition a certains cancers mais egalement repercussions psychosociales. En France, en 2003, 30% des adultes etaient en surpoids et 11% etaient obeses. L’augmentation des reserves adipeuses caracterisant l’obesite resulte d’un desequilibre de la balance energetique. Ce desequilibre releve d’interactions complexes, expliquant l’heterogeneite clinique et biologique de l’obesite humaine. L’espoir de voir l’epidemie maitrisee dans les annees a venir repose sans doute plus sur la mise en place d’actions coordonnees entre divers acteurs de la societe que sur l’attente d’un medicament specifique.

Points essentiels • Des indices biologiques d’une hyperactivite de l’axe corticotrope ont ete observes dans l’obesite abdominale commune, qui est cliniquement proche de celle de l’hypercorticisme. • Cette hyperactivite peut contribuer au developpement de l’obesite abdominale et de ses complications metaboliques et cardiovasculaires. • Plusieurs mecanismes peuvent en etre a l’origine: des facteurs genetiques, l’hygiene de vie (facteurs nutritionnels, sedentarite), mais egalement le stress chronique. • Des etudes cliniques methodologiquement indiscutables sont necessaires pour une evaluation objective du role du stress chronique dans cette pathologie.

Synthetic glucocorticoids treatment for their antiinflammatory and immunosuppressive activities for more than 3 weeks decreases corticotropic axis and induces a risk of adrenal insufficiency upon treatment withdrawal. Dose, duration and unknown individual factors play a role in the occurrence of adrenal insufficiency. Serum cortisol at 7-8 am, possibly completed by an 1-24 ACTH stimulation test makes the diagnosis. A scheme for care of patients is included with a progressive decrease of synthetic glucocorticoids dose, a replacement of this medication with physiological doses of hydrocortisone (in case of adrenal insufficiency) and a follow-up of endogenous secretion for detection of adrenal function recovery.

Introduction Le jeune du Ramadan, un des cinq piliers de l’Islam est un evenement majeur pour tous les musulmans. Le but de notre etude est d’analyser les attitudes des diabetiques et des medecins face au Ramadan. Materiels et methodes Il s’agit d’une etude transversale marseillaise realisee en 2007 sur 101 diabetiques musulmans et 101 generalistes sous forme de questionnaires de 54 et 29 questions, portant sur le fait de faire le Ramadan, les evenements survenus et les modifications therapeutiques conseillees. Resultats 51,5 % des patients font le Ramadan (13,5 % de type 1, 86,5 % de type 2). Parmi eux, 34,6 % n’en ont pas parle a leur medecin et 52,9 % en ont parle mais outrepassent l’interdiction du medecin. 7,7 % preferent en parler a l’Imam plutot qu’au medecin. 40,4 % patients se mettent en danger physiquement pendant le Ramadan (diabete avec complications recentes severes, Ramadan pendant la grossesse, refus de resucrage en cas d’hypoglycemie pour ne pas rompre le jeune (26 %), traitement non adapte). Cinq patients n’arretent pas leur prise de sulfamides de midi, ou maintiennent leur injection d’insuline rapide le midi. 80,9 % des patients sous insuline n’ont pas modifie leurs doses. Sur 101 medecins generalistes, 85,1 % disent avoir parle du Ramadan a leurs patients. 52,2 % conseillent a tous leurs patients diabetiques musulmans de ne pas le faire. Discussion Certains patients (multicompliques, insuffisants renaux ou dialyses, diabetes instables) font le Ramadan, sans que ce choix paraisse rationnel. Par ailleurs, les generalistes interdisent a leurs patients diabetiques de faire le Ramadan, sans qu’aucune veritable logique d’interdiction ne soit retrouvee. Conclusion Notre etude aborde la double approche patient-medecin face a la realisation du Ramadan, elle suggere de modifier les pratiques cliniques en favorisant l’explication systematique des modifications therapeutiques necessaires pour eviter des situations dangereuses pour le patient.
