Bone is involved in both phosphate-calcium and energetic metabolism. Osteocalcin, secreted by the osteoblasts, stimulates insulin secretion and improves insulin sensitivity. FGF-23, secreted by the osteoclasts, increases phosphate urinary excretion and is a marker of insulin resistance. Relationship between insulin-resistance, body fat and bone metabolism remains unclear. Therefore, the aim of this study was to evaluate osteocalcin and FGF-23 levels in diseases differing by bo...

Irisin is a myokine correlated with lean body mass, despite its association with cardiovascular events (Mantzoros 2014). Increased muscle volume and lipoatrophy have been reported in female FPLD (Ji JCEM 214). Our aim was to determine whether irisin could help to distinguish certain lipodystrophic obesities from FPLD.Methods and patients: Circulating irisin levels (EIA Phoenix) were measured in 20 LMNA-related FPLD, 19 normal-weighed controls (H) and 13 ...

Introduction: SDH genes mutations are associated with hereditary phaeochromocytoma and paraganglioma syndromes. We describe the case of a patient with SDHC related familial paraganglioma and pituitary adenoma.Case: A 65-year old man consulted for an incidentally discovered 7 cm abdominal mass on CT-scan, lateral to the right kidney, invading inferior vena cava, associated to a retroperitoneal adenomegaly and a lesion on the body of L2 vertebra with spina...

Familial Partial Lipodystrophy Syndromes (FPLD) are rare diseases characterized by partial lack of subcutaneous fat resulting in a severe metabolic syndrome and cardiovascular complications. Besides premature cell senescence, 2 main mechanisms are involved in FPLD: impaired adipocyte differentiation and lipid droplet, corresponding to two of the main causes of FPLD: LMNA-related FPLD2 and PLIN-related FPLD4. The objective of this study was to compare the clin...

Background: Lamin A/C mutations show heterogeneous phenotypes expanding from cardiopathies to lipodystrophies. LMNA-related heart disease has recently been shown to be associated with a high incidence of phenotypic progression and adverse arrhythmic and non-arrhythmic events. Anticipatory planning to prevent sudden death has been recommended in a multicentric cardiologic recruitment. Nevertheless the specific cardiac prognosis of R482-LMNA mutated patients, the hot-spot for pa...

The biological diagnosis of pheochromocytoma (P) and/or paraganglioma (Pgg) relies on the identification of excessive secretion of the metanephrines. Chomogranin A (CgA) is a general indicator of neuroendocrine tumours that is highly expressed in P and correlate with tumour mass and secretory activity. The CgA test could be indicated as a useful test in patients with false positive metanephrines results. The aim of our prospective bi-centre study, is to evaluate the performanc...

The aim of this retrospective study was to compare the long-term metabolic evolution of a cohort of patients treated for adrenal insufficiency (AI), and the best biological parameters of a good balance.Seventy patients with AI (mean age 41 years (±16); 60% female) were followed during a median 6-year period (2–16 years): 38 after bilateral adrenalectomy (60% Cushing) and 32 after AI of medical origin (62% polyglandular autoimmune syndrome). BMI...

Introduction: Few studies to date have attempted to evaluate the early efficacy of first-generation somatostatin analogs in somatotroph macroadenomas.Objective: To investigate the short-term efficacy of primary therapy with lanreotide 120 mg on tumor shrinkage and ophthalmologic symptoms in newly diagnosed patients with acromegaly.Design and patients: This single-center retrospective study included 21 patients who were newly diagno...

Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder affecting women in reproductive age. Women with PCOS exhibit 2-3x higher levels of circulating Anti-Müllerian Hormone (AMH) as compared to healthy women and it is unclear if the elevation of AMH is a bystander effect or is driving the condition. Moreover, PCOS has a strong heritable component, however the etiopathology of the disease and the mechanisms underlying its transmission remain t...

Background: Few studies to date have attempted to measure serum anti-Müllerian hormone (AMH) levels in adult men, and solid references ranges have not yet been defined on a large cohort.Objective: In this study, we aimed to first establish the reference ranges for serum AMH and AMH-to-total testosterone ratio (AMH/tT) in adult males. Secondly, we investigated the relationship between serum AMH and both reproductive hormones and semen parameters....
