Contribution of NGS in the genetic analysis of neuroendocrine tumors associated with Multiple Endocrine neoplasia type 1 (MEN 1)

Hamny Illias , Françoise Borson-Chazot , Sophie Giraud

Objective: Next Generation Sequencing technique (NGS) allows the analysis of a whole set of genes in the same time. It is, now, used, in our laboratory for the genetic screening of neuroendocrine tumors associated with Multiple Endocrine neoplasia type 1(MEN1)The objective of the present study was to assess the efficiency of this approach and the relevance of the results regarding the current genetic screening recommendations.Methods: The data of all pat...

Physiological regulation of brown adipose tissue in obesity by mild-cold exposure, a B3-agonist and exercise training at thermoneutrality

Aldiss Peter , Lewis Jo , Ebling Fran , Budge Helen , Symonds Michael

Background: Therapeutic activation of thermogenic brown adipose tissue (BAT) is a potential strategy to prevent obesity and metabolic disease in humans. However, it is now recognised that rodent studies examining BAT physiology are carried out at sub-thermoneutral temperatures (e.g. ~20°C), and are not translationally relevant to humans as BAT is ‘hyperactive’. Therefore, the aim of this study was to determine the effect of common regulators of BAT metabolism wh...

Efficacy of insulin detemir treatment in type 2 diabetes mellitus is associated with a allele od the catechol o-methyltransferase polymorphism

Bozek Tomislav , Blazekovic Antonela , Perkovic Matea Nikolac , Gotovac Kristina , Smircic-Duvnjak Lea , Pivac Nela , Borovecki Fran

Introduction: Growing evidence suggests that nutrients and hormonal signals converge and directly act on brain centers, leading to changes in energy metabolism and stable body weight over time. Catechol O-methyltransferase (COMT) is one of the major enzymes involved in catecholamine and estrogen degradation. There is a well-established association between the COMT Val108/158Met polymorphism and abdominal obesity, blood pressure increase and T2DM. Basal insulin detemir besides ...

Refeeding syndrome – an unexpected clinical case

Puga Francisca , Baptista Patrícia , França Margarida , Araújo Correia João

Refeeding syndrome can be defined as the potentially fatal shift in fluids and electrolytes that may occur after the reintroduction of feeding after a period of starvation or fasting in malnourished patients. The hallmark characteristic of refeeding syndrome is hypophosphatemia. However, the syndrome is complex and may also feature abnormal sodium and fluid balance, changes in glucose, protein and fat metabolism, hypokalemia, hypomagnesemia and thiamine deficiency. The underly...

The vulnerability of prepubertal ovarian steroidogenesis to AhR-mediated TCDD action occurs during a time-restricted window in mice

Devillers Marie , Petit Florence , Giton Frank , François Charlotte , Juricek Ludmila , Coumoul Xavier , Magre Solange , Cohen-Tannoudji Joëlle , Guigon Celine

Background: In females, timing of puberty and fertility require estradiol (E2) action at the infantile and late juvenilestages and are tightly influenced by environmental cues. A regulator of intra-ovarian E2 synthesis during reproductive life is the aryl hydrocarbon receptor (AhR). However, its action on E2 synthesis and its capacity to mediate the effect of endocrine disrupting chemicals (EDC)s has not been thoroughly evaluated during the prepubertal period.<p class="abs...

Adrenocortical carcinosarcoma: first european case report

Somda Frédéric , Leger Julie , Guy Laurent , Norha Olivier , Desbiez Françoise , Boiteux Jean-Paul , Kemeny Jean-Louis , Thieblot Philippe , Tauveron Igor

Adrenocortical sarcoma is an extremly rare tumour associated with a quite pejorative evolution.We report the case of a fifty-eight years old woman presenting a chronic asthenia and acute flank pain. She had no hypertension, no clinical sign of virilization or hypercorticism. Abdominal ultrasonography revealed an 8 centimeters mass above the right kidney. CT scan aspect evoked an adrenal carcinoma embolizing vena cava. Hormonal assays did not reveale any inappropriate secretion...

Precipitating factors of diabetic ketoacidosis

Matas Nino , Barač Nekić Anja , Čović Antonela , Vrandečić Fran , Bačun Tatjana , Feldi Ivan , Kaštelan Darko , Dušek Tina , Zibar Tomšić Karin , Novak Anela

Introduction: Diabetic ketoacidosis (DKA) is one of the most serious acute complications of diabetes mellitus (DM). In some studies, infections have been shown to be a precipitating factor in half of the subjects. On the other hand, several recent studies emphasise that poor treatment adherence is also a common cause of DKA.Objective: To identify the most common precipitating factors for DKA in the Republic of Croatia.Patients and ...

Autocrine-paracrine pathways in primary adrenal disorders

Lefebvre Hervé , Contesse Vincent , Cartier Dorthe , Perraudin Véronique , Delarue Catherine , Vaudry Hubert , Bertherat Jérôme , Plouin Pierre-François , Kuhn Jean-Marc , Louiset Estelle

It is now well demonstrated that, in the human adrenal gland, aldosterone and cortisol productions are stimulated by autocrine/paracrine factors, like serotonin (5-HT) and arginine vasopressin (AVP). Several data indicate that these signals may also be involved in the regulation of corticosteroidogenesis in adrenocortical hyperplasias and tumors. 5-HT is detected in clusters of steroidogenic cells in aldosterone-producing adrenocortical adenomas (APAs), and in both ACTH-indepe...
