Background: Transgender people often use gender-affirming hormone therapy to obtain physical characteristics that comply with their experienced gender. Transgender women use estradiol, usually with anti-androgens. Transgender men use testosterone. It has been reported that gender-affirming hormone therapy is associated with increased risk of acute cardiovascular events, however, this data constitutes largely of low quality evidence. We aimed to investigate the long-term incide...

Background: Individuals with diabetes are at higher risk for developing arterial disorders. The toe-brachial index (TBI) is associated with peripheral vascular disease, and aortic pulse-wave velocity (aPWV) is currently the gold standard for assessing arterial stiffness. High concentrations of plasma arginine vasopressin (AVP) preferentially stimulate V1a receptors, which affect the vascular bed and may contribute to cardiovascular (CV) complications. Copeptin, a more stable p...

Background: Pheochromocytoma is associated with systemic inflammation, but the underlying mechanisms are unclear. Hypothesising a putative effect of catecholamines on immune cells, we investigated the relationship between plasma metanephrine levels and haematological parameters – as surrogates for systemic inflammation – in patients with pheochromocytoma. Moreover, we aimed to assess the influence of preoperative α-blockade treatment on the inflammation-based sc...

The adrenal cortex synthesizes glucocorticoids that are essential for metabolic homeostasis and modulation of immune responsiveness. Glucocorticoid-producing cells, located in the zona fasciculata (zF), constitute the critical effector of the HPA axis that serves to mediate the mammalian stress response. Dysregulation of glucocorticoid function results in significant morbidity with complete deficiency being incompatible with life. While the zF is composed of heterogenous cell ...

Objectives: Clinical studies indicate that primary aldosteronism (PA) is associated with dysregulated bone homeostasis. The aim of this study was to evaluate the incidence of hip fractures in patients with PA.Methods: We studied a nationwide cohort of 2419 patients with PA (1997-2019) and 24 187 age and sex matched controls from the general population. Hip fractures were identified by ICD codes in the Swedish National Patient Register. We estimated hazar...

Background: Long-term glucocorticoids can result in iatrogenic Cushing’s syndrome with adrenal suppression. Most patients reactivate their hypothalamic-pituitary-adrenal axis once they’re weaned off glucocorticoids. During glucocorticoid withdrawal, many clinicians switch patients to hydrocortisone to benefit from its short half-life1. However, in some patients, hypothalamic-pituitary-adrenal axis recovery is delayed despite the above. It is unclear whethe...
