Cushing disease

Management of Cushing's syndrome (CS) can be particularly challenging in older patients, due to the lack of several clinical features associated with cortisol excess along with a greater burden of comorbidities in them, as compared with the younger. Moreover, interpretation of diagnostic tests could be influenced by age-related physiological changes of cortisol secretion. While mortality is higher and quality of life is more impaired in the elderly with CS as compared with the younger, there is currently no agreement on the most effective therapeutic options in aged individuals, and safety data concerning medical treatment are scanty...

OBJECTIVE: This study aims to evaluate the impact of surgical intervention on anxiety levels in patients with various types of pituitary adenoma (PA). METHOD: A systematic review was conducted following PRISMA guidelines until October 2022, searching Embase, PubMed, Web of Sciences, and Scopus. RESULTS: A total of 32 studies were included, encompassing 2681 patients with the mean age of 53.33 ± 6.48 years (43.4% male). Among all subtypes, 664 diagnosed with Cushing's disease (25...

PURPOSE: Cushing's disease is associated with substantial morbidity and impaired quality of life (QoL) resulting from excess cortisol exposure. The current study explored improvements in clinical signs and additional specific manifestations of hypercortisolism during osilodrostat (potent oral 11β-hydroxylase inhibitor) therapy by degree of control of mean urinary free cortisol (mUFC). METHODS: LINC 3 (NCT02180217) was a prospective, open-label, 48-week study of osilodrostat (starting dose: 2 mg bid; maximum: 30 mg bid) that enrolled 137 adults with Cushing's disease and mUFC > 1...

OBJECTIVE: Somatic variants in the ubiquitin-specific protease 8 (USP8) gene are the most common genetic cause of Cushing disease. We aimed to explore the relationship between clinical outcomes and USP8 status in a single centre. DESIGN, PATIENTS AND MEASUREMENTS: We investigated the USP8 status in 48 patients with pituitary corticotroph tumours. A median of 62 months of follow-up was conducted after surgery from November 2013 to January 2015. The clinical, biochemical and imaging features were collected and analysed...

Endogenous Cushing's syndrome (CS) is a rare disease characterized by a glucocorticoid excess. If inadequately treated, the latter can lead to increased morbidity and mortality. Surgical removal of the underlying tumor is the first line treatment but is sometimes not feasible or even contraindicated. Additionally, in cases with severe CS, rapid control of hypercortisolism may be required. In these scenarios steroidogenesis inhibitors represent a therapeutic alternative to surgery. Over the last years, the knowledge on the broad therapeutic effects of steroidogenesis inhibitors and the number of available drugs have increased...

BACKGROUND: A far more common disease than Cushing's syndrome is subclinical hypercortisolism or mild autonomous cortisol secretion (MACS), with an overall prevalence of 0.2-2%. OBJECTIVE: This review aims to shed light on the prevalence, screening and diagnostic criteria, comorbidities, and management of Mild Autonomous Cortisol Secretion (MACS). METHODS: Studies eligible targeted MACS regarding prevalence, screening, comorbidities, management, and clinical outcome...

Glucocorticoid withdrawal syndrome is a challenging clinical phenomenon that can complicate the postsurgical recovery of Cushing syndrome. It is characterized by physical tolerance and dependence to supraphysiologic glucocorticoid exposure during active Cushing syndrome followed by the abrupt decline in cortisol levels after surgical treatment. The symptoms of glucocorticoid withdrawal often overlap with those of postoperative adrenal insufficiency and can be difficult for patients to cope with and for clinicians to treat...

OBJECTIVE: ACTH-producing pancreatic NETs have a propensity to metastasize, and in patients with metastases, there is no established method yet to precisely determine if the excess ACTH is produced by the primary or the metastatic tumors. Localizing the source of production of ACTH in such cases is important for devising suitable treatment strategies and evaluating the benefit of local therapies from the viewpoint of control of Cushing's syndrome. METHODS: We performed the selective arterial calcium injection (SACI) test combined with selective portal and hepatic venous sampling in a 32-year-old female patient with ectopic ACTH-producing pancreatic NET and liver metastases...

BACKGROUND: Literature reporting positive outcomes from the Good Life with osteoArthritis in Denmark (GLA:D®) program in Australia mainly involves patients attending private physiotherapy services. OBJECTIVE: Evaluate the feasibility of implementing GLA:D® in Australian public hospitals. DESIGN: Implementation study in three metropolitan tertiary public hospitals over six months. METHOD: Patients aged ≥18 years with knee or hip joint-related problems deemed appropriate for non-surgical care were invited to participate in GLA:D®...

The most common form of hypercortisolism is iatrogenic Cushing's syndrome. Lipodystrophy and metabolic disorders can result from the use of exogenous glucocorticoids (GC). Adipocytes play an important role in the production of circulating exosomal microRNAs, and knockdown of Dicer promotes lipodystrophy. The aim of this study is to investigate the effect of GCs on epididymal fat and to assess their influence on circulating microRNAs associated with fat turnover. The data indicate that despite the reduction in adipocyte volume due to increased lipolysis and apoptosis, there is no difference in tissue mass, suggesting that epididymal fat pad, related to animal size, is not affected by GC treatment...

BACKGROUND: Prolactinomas are common tumours that significantly reduce quality-of-life (QOL) due to sellar mass effect, secondary hypogonadism, and the peripheral effects of prolactin. Understanding the factors that influence QOL would provide insights into therapeutic targets to optimise patient outcomes and improve wellbeing in prolactinoma. METHODS: A systematic review was performed in accordance with the PRISMA statement. Studies that reported patient QoL using validated metrics were included...

BACKGROUND: We analyze the long-term outcome of surgery for Cushing's syndrome (CS) and the influence of the extent of surgical resection on the duration of postoperative cortisone substitution. METHODS: One-hundred forty-one patients (129 female, 12 males; mean age: 45.7 ± 12.8 years) operated between January 2000 to June 2020 were included in the analysis. Patients suffered from manifest (124) or subclinical (17) CS due to benign unilateral adrenal neoplasia...

Cushing's syndrome is a rare disease that has a different primary etiology, most often due to chronic hypercortisolism. In addition to the defined causes, in contrast to the general population, the observed etiology in pregnant women is a benign adrenocortical adenoma, less often bilateral hyperplasia of the adrenal glands of hypothalamic-pituitary origin or Cushing's disease, and malignant adrenal root adenoma. In this study, we present the case of a 41-year-old pregnant woman experiencing her first pregnancy...

The majority of incidentally discovered adrenal tumours are benign adrenocortical adenomas and the prevalence of adrenocortical adenomas is around 1-7% on cross-sectional abdominal imaging. These can be non-functioning adrenal tumours or they can be associated with autonomous cortisol secretion on a spectrum that ranges from rare clinically overt adrenal Cushing syndrome to the much more prevalent mild autonomous cortisol secretion (MACS) without signs of Cushing syndrome. MACS is diagnosed (based on an abnormal overnight dexamethasone suppression test) in 20-50% of patients with adrenal adenomas...

PURPOSE: Surgical therapy represents the first-line treatment for endogenous Cushing's syndrome (CS). While postoperative glucocorticoid replacement is mandatory after surgical remission, the role of perioperative glucocorticoid therapy is unclear. METHODS: We recruited patients with central or adrenal CS in whom curative surgery was planned and patients who underwent pituitary surgery for other reasons than CS as a control group. Patients did not receive any perioperative glucocorticoids until the morning of the first postoperative day...

In the development of proteins, aptamers, and molecular imprints for diagnostic purposes, a major goal is to obtain a molecule with both a high binding affinity and specificity for the target ligand. Cushing syndrome or Addison's disease can be diagnosed by cortisol level tests. We have previously characterized and solved the crystal structure of an anti-cortisol (17) Fab fragment having a high affinity to cortisol but also significant cross-reactivity to other glucocorticoids, especially the glucocorticoid drug prednisolone...

CONTEXT: Hypercortisolism frequently induces trabecular bone loss, more pronounced at the lumbar spine, resulting in osteoporosis, and thus an increase in fracture risk. Several studies have shown bone mass recovery in patients with Cushing's disease (CD) after treatment. OBJECTIVE: To examine treatment effects on TBS (trabecular bone score) in addition to aBMD (areal bone mineral density) in a cohort of patients with CD. DESIGN AND SETTING: Single-center retrospective longitudinal study in patients diagnosed with CD and successfully treated following surgery and/or medical treatment...

BACKGROUND: Laparoscopic adrenalectomy is widely performed for a number of hormone-producing tumors and postoperative management depends on the hormones produced. In the present study, we conducted a retrospective analysis to clarify the risk factors for postoperative complications, particularly postoperative fever after laparoscopic adrenalectomy. METHODS: We analyzed 406 patients who underwent laparoscopic adrenalectomy at our hospital between 2003 and 2019. Postoperative fever was defined as a fever of 38 °C or higher within 72 h after surgery...

CONTEXT: Spatial transcriptomic (ST) analysis of tumors provides a novel approach to studying gene expression along with the localization of tumor cells in their environment to uncover spatial interactions. DESIGN: We present ST analysis of corticotroph pituitary neuroendocrine tumors (PitNETs) from formalin-fixed, paraffin-embedded tissues. ST data were compared to immunohistochemistry results. Gene expression profiles were reviewed for cluster annotations, and differentially expressed genes were used for pathway analysis...

BACKGROUND: Endocrine regulation of bone metabolisms is the focus of the "Skeletal Endocrinology" series of meetings. AIMS: To report on the outcome of the discussion on the role of vitamin D/PTH axis in endocrine osteopathies held during the 10th Skeletal Endocrinology Meeting which took place in Stresa (Italy) in March 2023. OUTCOMES: Vitamin D/PTH axis has relevant influence on several outcomes in the general population and in patients affected by endocrinopathies such as hypoparathyroidism and secreting pituitary adenomas...
