Purpose: Adrenal incidentalomas (AIs) and pituitary incidentalomas (PIs) have become frequent findings in the last two decades due to the widespread use of cross-sectional imaging in clinical practice. This review investigates the prevalence of endogenous hypercortisolism in patients with AIs and PIs. We aim to underscore the importance of early detection and management of endogenous hypercortisolism in this subset of patients to mitigate associated cardiometabolic complications and reduce mortality., Methods: We performed a PubMed literature search to provide updates regarding the prevalence of endogenous hypercortisolism in patients with AIs and PIs, the demographic and clinical characteristics of the studied populations, and the diagnostic test accuracy for early identification of endogenous hypercortisolism., Results: Hypercortisolism, especially mild autonomous cortisol secretion (MACS), was identified in a notable proportion of patients with AIs. MACS was associated with increased cardiometabolic risks, contributing to an elevated overall mortality rate in this cohort. Furthermore, PIs were found to be linked with Cushing's disease in a subset of patients, emphasizing the need for thorough evaluation and monitoring., Conclusion: Early diagnosis and appropriate management of endogenous hypercortisolism are essential in preventing complications and improving patient outcomes. As the presence of undetected hypercortisolism is associated with clinical complications over time, the accurate identification of high-risk populations to screen remains crucial., (© 2024.

Background: Various glucocorticoid replacement therapies (GRTs) are available for adrenal insufficiency (AI). However, their effectiveness in restoring glucocorticoid rhythm and exposure lacks adequate biochemical markers. We described the diurnal salivary cortisol (SalF) and cortisone (SalE) rhythm among different GRTs and analysed the associations between saliva-derived parameters and life quality questionnaires., Methods: Control subjects (CSs, n = 28) and AI patients receiving hydrocortisone (HC, n = 9), cortisone acetate (CA, n = 23), and dual-release hydrocortisone once (DRHC-od, n = 10) and twice a day (DRHC-td, n = 6) collected 9 saliva samples from 07:00 to 23:00. Patients compiled Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Scale, and Addison disease-specific quality-of-life questionnaires. SalE and SalF were measured by liquid chromatography-mass spectrometry. Exposure was monitored using SalE for HC and DRHC and SalF for CA. Area under the curve (AUC) was computed. Different GRTs were compared by Z-scores calculated from saliva-derived parameters. Questionnaire results predictors were evaluated with multiple regression analysis., Results: Compared with controls, all GRTs resulted in glucocorticoid overexposure in the morning. Hydrocortisone, CA, and DRHC-td caused overexposure also in afternoon and evening. Compared with other treatments, CA determined increased Z-score-07:00 (P < .001), DRHC-td determined increased Z-score-AUC07:00→14:00 (P = .007), and DRHC-od induced lower Z-score-AUC14:00→23:00 (P = .015). Z-scores-AUC14:00→16:00 ≥ .619 best predicted questionnaire scores., Conclusions: None of the GRTs mimics normal glucocorticoid rhythmicity and exposure. SalE, SalF, and Z-score may be useful markers for monitoring and comparing different GRTs. Excess glucocorticoid in early afternoon best associated with depressive symptoms and worse life and sleep quality., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2024.

Objective: Mild autonomous cortisol secretion (MACS) has been associated with a higher prevalence of osteoporosis, although most data rely on single-center studies with limited sample size. We aimed to assess the prevalence of fragility fractures and contributing factors in a large cohort of patients with adrenal incidentalomas., Design and Methods: Medical records of 1023 patients with adrenal incidentalomas from 1990 to 2019 were reviewed, and 735 patients were selected. Clinically obtained electronic radiological images closest to first endocrine evaluation, such as lateral views of spine X-rays or CT thoraco-abdominal scans, were reviewed to screen for asymptomatic morphometric vertebral fractures. Clinical fragility fractures, hormonal, and dual-energy x-ray absorptiometry (DXA) indices were also recorded., Results: Four hundred seventy-four patients had nonfunctioning (NF) adrenal incidentalomas, 238 had MACS and 23 adrenal Cushing's syndrome (AC). Prevalence of fragility fractures was different (P = .018) between groups, respectively, 24.1% (NF), 34.0% (MACS), and 30.4% (AC), with significant difference between NF and MACS (P = .012). When analyzed separately by sex and menopausal status, this difference remained significant in postmenopausal women (P = .011), with a fracture prevalence of 22.2% (NF) and 34.6% (MACS). Fracture prevalence was similar in males. Women with MACS aged ≥65 years reported a 48.8% prevalence of fractures, as compared with 29.5% in NF (P < .01). In postmenopausal women, fragility fractures were associated with age (odds ratio [OR] 1.1, P < .001), smoking (OR 1.8, P = .048), and 1 mg-dexamethasone suppression test (DST) cortisol (OR 3.1, P = .029), while in men, only age was associated with fragility fractures., Conclusions: A considerable fracture burden was shown in postmenopausal women with adrenal incidentalomas and MACS, with clinical implications for the evaluation and management of bone metabolism., Competing Interests: Conflicts of interest: None declared., (© The Author(s) 2023.
