Twenty-one unmedicated, sequentially admitted psychiatric patients of either sex and four male healthy volunteers were given an intravenous injection of 2.5 mg morphine. Blood samples were drawn immediately before and at 30-minute intervals for 3 hours after the injection and assayed for cortisol. Morphine suppressed cortisol secretion. Early resumption of cortisol secretion (escape) was more frequent in patients with a diagnosis of major depressive disorder and with abnormal dexamethasone suppression test results. The sensitivity of this infusion paradigm for the diagnosis of major depressive disorder was 40%, and the specificity was 82%. The implications of these findings for the pathophysiology of depression are discussed.

Telomere length (TL) is considered a biomarker of aging, and short TL in leukocytes is related to age and stress-related health problems. Cumulative lifetime stress exposure has also been associated with shorter TL and age-related health problems, but the mechanisms are not well understood. We tested in 108 individuals whether shorter TL in leukocytes is observed in individuals with the GABRA6 TT genotype, which has been associated with dysregulation of hypothalamic-pituitary-adrenal axis activity (the main biological stress system) compared to the CC genotype.

Purpose: Our study evaluated skeletal muscle mass, function and quality among mild autonomous cortisol secretion (MACS) patients and non-functioning adrenal incidentaloma (NFAI) patients in comparison with the control group without adrenal mass.
Methods: 63 NFAI (49 female, 14 male) and 31 MACS (24 female, 7 male) patients were included in the study. As the control group, 44 patients (31 women, 13 men) who were known to have no radiological adrenal pathology on computed tomography or magnetic resonance imaging performed for other reasons were selected.

Background: Classic congenital adrenal hyperplasia, primarily due to 21-hydroxylase deficiency, leads to impaired cortisol and aldosterone production and excess adrenal androgens. Lifelong glucocorticoid therapy is required, often necessitating supraphysiological doses in youth to manage androgen excess and growth acceleration. These patients experience higher obesity rates, hypertension, and glucose metabolism issues, complicating long-term health management.

Methods: Pooled analysis of two Phase III osilodrostat studies (LINC 3 and LINC 4), both comprising a 48-week core phase and an optional open-label extension. Changes from baseline in systolic and diastolic BP (SBP and DBP), fasting plasma glucose (FPG), and glycated hemoglobin (HbA) were evaluated during osilodrostat treatment in patients with/without hypertension or diabetes at baseline.

Objective: One of the most severe endocrine side effects of immune checkpoint inhibitors (ICI) is hypophysitis leading to adrenal insufficiency. Recovery is rare, although it has been reported after high-dose glucocorticoid treatment. This is the first randomised study to evaluate whether hormonal recovery differs in patients treated with high-dose glucocorticoids versus glucocorticoid replacement therapy.
