Importance: Adrenal insufficiency is a life-threatening condition complicating heterogenous disorders across various disciplines, with challenging diagnosis and a notable drug-induced component.Objective: To describe the spectrum and main features of drug-induced adrenal insufficiency through adverse drug event reports received by the Food and Drug Administration (FDA).Design: We conducted a retrospective disproportionality analysi...

Background: Evaluation of steroid replacement therapy (SRT) in adrenal insufficiency (AI) is challenging for the lack of reliable parameters. Measurement of salivary cortisol and cortisone emerged as a non-invasive tool for AI management, however poorly investigated. Aim: To analyse the cortisol and cortisone circadian rhythm in normal controls (NC) and patients with primary AI (PAI) under different SRTs, and to identify useful biomarkers. <p class="...

Background: Altered sleep quality and duration have been reported in 26-67% of patients with type 1 diabetes (T1D). However, differences in study designs, populations, and methods of sleep quality assessment have led to heterogeneous results in terms of association with clinical data and blood glucose parameters.Aims: To investigate the sleep quality of a large cohort of adult patients with autoimmune diabetes under insulin treatment, and to analyze the ...

Background: Moving from childhood to adulthood is a challenging process for individuals with type 1 diabetes (T1D), transition has been defined as the planned movement from pediatric to adult department.Aim: To assess glucometabolic control, prevalence of autoimmune disorders, and use of glucose sensors in patients with type 1 diabetes after transition to adult care.Methods: We retrospectively evaluated HbA1c, prevalence of patient...

Background: DNA methylation has been recognized as a putative regulatory mechanism for CYP11B2 in primary hyperaldosteronism. We aimed to investigate the DNA methylation and the expression of a panel of genes encoding several enzymes involved in steroidogenesis in adrenocortical benign tumors.Methods: We collected a total of 60 adrenocortical tissues, including 9 non-functioning adrenal adenomas, 9 adenomas associated with autonomous cortisol se...

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...

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,...

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: 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...
