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...

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: The diagnosis of non-HIV lipodystrophies is challenging, especially since borderline forms with type 2 diabetes have been described (Strickland Diabetes Care 2013).Objective: To identify the most specific anthropometric and biological parameters enabling to differentiate lipodystrophic from obese and control subjects.Methods: This prospective study (clin.gov 2009-AO-1169-48) included 94 patients divided in 3 groups ad...

Introduction: Guidelines recommend using first-line tests, including 24-hour urine-free cortisol (UFC), overnight 1-mg dexamethasone suppression test (DST), and late-night salivary cortisol (LNSC) for the positive diagnosis of hypercortisolism. Unfortunately, LNSC access is constrained in certain institutions, requiring, as an alternative, hospitalization for midnight plasmatic cortisol (F00h) measurement. This study explores the diagnostic potential of afternoon plasma cortis...
