Introduction: Several risk factors are involved in post-liver transplantation osteoporosis. Immunosuppressive agents, glucocorticoids, decreased renal function associated with secondary hyperparathyroidism and immobilization are the main determinants of fragility fractures in this population. Denosumab is highly effective in increasing bone mineral density (BMD) and preventing fragility fractures. However, the efficacy of denosumab in liver transplantation osteoporosis has nev...

Introduction: The adrenal morphology in congenital adrenal hyperplasia (CAH) is poorly described in the literature, so that adrenal radiological evaluation is not recommended in patients with CAH. The aim of this study was to evaluate the adrenal morphology in a large cohort of adult patients with CAH due to 21-hydroxylase deficiency and its correlation with the subtype of CAH (non-classical-NCAH, simple virilizing-SV, or salt wasting-SW), the hormonal status and the treatment...

In a previous study we found mutations in the main catalytic subunit of protein kinase A (PKA Cα) to be responsible for cortisol-secreting adrenocortical adenomas (ACAs). These mutations interfere with the formation of a stable holoenzyme, thus causing constitutive PKA activation. More recently, we identified additional mutations affecting PKA Cα in ACAs associated with overt Cushing syndrome: Ser213Arg_Leu212_Lys214insIle-Ile-Leu-Arg, Cys200_Gly201insVal, Trp197Arg,...

Introduction: Purpose of this study is to find a radiological score and to correlate radiological characteristics of adrenal adenomas and functional parameters to predict subclinical glucocorticoid secretion.Methods and materials: This retrospective study included 55 patients with adenomas, investigated through CT with adrenal protocol assessing diameters, HU values of the unenhanced and contrast enhanced phases (enhanced–E, and 15 min delayed enhan...

Steroid profiling by liquid chromatography–tandem mass spectrometry (LC–MS/MS) offers an accurate and simultaneous detection of a panel of steroids with several advantages over traditional assays. However, only a few studies have investigated the steroid profiling in sporadic adrenocortical adenomas. Our aim was therefore to investigate steroid secretion by LC–MS/MS in patients with non-secreting adrenocortical adenomas (NSA) and subclinical hypercortisolism (SH...

Hyperandrogenic disorders cause psychological implication in young girls, limiting the quality of life. Salivary cortisol (SalF) testing was proved to be useful in the evaluations of acute stress responses. Aim of this study was to investigate SalF responses to a stressor event in late adolescent females. We selected 165 drug-free females aged 16–19 years from a cross-sectional epidemiological study. Saliva was collected in the morning before and after a stressor event co...

Introduction: The relationship between food intake and hypothalamic–pituitary–adrenal (HPA) axis has been studied in the development of visceral adiposity and obesity. The HPA axis may interact with the reward system, thus influencing food choices. On the other hand, it has been shown that macronutrients differently modulate the HPA axis activity.The aim of this study was to evaluate the dietary habits in subjects with adrenal masses (adenoma o...

Introduction: Women with polycystic ovary syndrome (PCOS) are considered to have increased risk of cardiovascular disease (CVD), even though the syndrome encompasses hugely varying phenotypes. Research into CVD prevention demonstrated a variety of biochemical and ultrasound (US) markers predicting risk in the general population, but those are sparsely utilised for PCOS, in part due to the patients’ therapeutic goals.Aim: To evaluate if PCOS type or...

Background: Steroid profiling by mass spectrometry (MS) provided novel insights into the pathogenesis of adrenocortical tumors and hypercortisolism. The aims of the study were (I) to analyze the steroid profiling by liquid chromatography-tandem MS (LC-MS/MS) in a large cohort of patients with adrenal incidentalomas and (II) to investigate the relationship between steroid profile and clinical outcomes.Methods: We included 307 patients with mono- and bilat...

Context: Autonomous cortisol secretion (ACS) has been associated with a higher prevalence of osteoporosis and fragility fractures in several studies. However, the data rely on heterogeneous studies and criteria for osteoporosis screening in this population are still debated.Objective: To assess the prevalence of fragility fractures and contributing factors in a large cohort of patients with adrenal incidentalomas.Methods: We review...
