Introduction: The role of glucocorticoids in the regulation of GH secretion is not well defined. Hypercortisolism inhibits GH secretion, but also hypocortisolism is correlated with impaired GH response to dynamic tests. This study was aimed to evaluate the GH reserve after GHRH+arginine test in patients with Addison’s disease (AD) and in operated patients with Cushing’s disease (CD).Design: Twelve AD patients (6M, 6F, aged 52±3.4 years, BM...

Hypogonadism occurs in myotonic dystrophy (DM) type 1 and 2, a multisystemic autosomal dominant disorder. DM patients have genetically induced insulin-resistance (IR) and visceral obesity, providing a model to study the impact of metabolic disruptions on hypogonadism. We assessed hypothalamic-pituitary-gonadal function and metabolic features in 22 DM1 and 8 DM2 males (mean±S.D., 46±11years). Hypogonadism, defined as total testosterone (T)<320 ng/dl...

Primary hyperparathyroidism (PHPT) negatively affects renal function. It is known that chronic kidney disease is a predictor of cardiometabolic diseases. Cystatin C (cystC), an alternative measure of renal function, has been associated with adverse cardiovascular events and cardiometabolic risk factors. This study was aimed to evaluate serum cystC, its relationships with PTH and cardiometabolic risk in patients with PHPT.The following parameters were mea...

Introduction: Myotonic dystrophy (DM) type 1 and 2 are multisystemic autosomal dominant disorders with visceral obesity, insulin resistance and hypogonadism. The prevalence of metabolic risk factors for coronary artery disease (CAD) in DM is not well defined, particularly in patients affected by DM2, a milder and clinical challenging condition.Methods: We assessed the frequency of CAD risk factors in 31 male DM1 (44±11 years) and 13 male DM2 (54&#17...

Introduction: Hypogonadism occurs in myotonic dystrophy (DM) type 1 and 2, a multisystemic autosomal dominant disorder with insulin resistance and visceral obesity. DM patients provide a model to investigate the impact of metabolic alterations on hypogonadism.Methods: We assessed Leydig and Sertoli cell functions and metabolic features in 32 DM1 (44+11 years),13 DM2 patients (54+9 years) and 32 age and BMI-matched controls.Results:...
