Sex differences in clinical picture of ACTH-dependent Cushing's syndrome are controversial, except for the known higher prevalence in females. We compared a broad range of potential differences to enable a more accurate understanding of the clinical picture of sex-specific ACTH-dependent Cushing's syndrome. Cohort study including consecutive patients with ACTH-dependent Cushing's syndrome from Leiden and Berlin diagnosed between 2000 and 2016. We compared clinical presentation, biochemical parameters, diagnostic tests, surgical outcome, and comorbidities between men and women. We included 130 patients: 37 males and 93 females. With similar cortisol concentrations, ACTH concentrations were higher in males than females at time of diagnosis (median: 116 vs. 57 ng/L). The prevalence of osteoporosis was higher in males than in females (48.6 vs. 25.0%), persisting after surgery, with more vertebral fractures (16.2 vs. 5.4%) before surgery. Males showed more anemia (75.9 vs. 36.8%) after surgery. There were no differences in etiology, pituitary tumor size, diagnostic and therapeutic strategy, or surgical outcome between sexes. Based on this study, males and females with ACTH-dependent Cushing's syndrome present different clinical patterns. However, these differences do not justify different diagnostic strategies or treatment based on sex, considering the similar surgical outcome. Clinicians should be alert to diagnose accompanying osteoporosis (with fractures) in male patients with ACTH-dependent Cushing's syndrome.

Patient signalment and aetiology of hypercortisolism in Australian dogs with Cushing's syndrome.
Aust Vet J
January 2025
Vetnostics, Macquarie Park, New South Wales, Australia.
Objective: Patient characteristics of Cushing's syndrome differ between countries and have not been assessed in the Australian dog population. This study describes signalment and distribution of adrenocorticotropic hormone (ACTH)-dependent hypercortisolism (ADH) and ACTH-independent hypercortisolism (AIH) in Australian dogs.
Animals: Two-hundred client-owned dogs that had endogenous ACTH concentrations measured by radioimmunoassay.
Mineralocorticoid axis activity and cardiac remodeling in patients with ACTH dependent Cushing's syndrome.

Background: Arterial hypertension and left ventricular hypertrophy and remodeling are independent cardiovascular risk factors in patients with Cushing's syndrome. Changes in the renin-angiotensin system and in the mineralocorticoid axis activity could be involved as potential mechanisms in their pathogenesis, in addition to cortisol excess.
Methods: In this ancillary study of our previous study prospectively investigating patients with ACTH-dependent Cushing's syndrome by cardiac magnetic resonance imaging (NCT02202902), 11 patients without any interfering medication were cross-sectionally compared to 20 control subjects matched for age, sex and body mass index.

Article Synopsis
- Non-neoplastic hypercortisolaemia, or pseudo-Cushing's syndrome (PCS), can occur due to various health conditions like depression, obesity, and diabetes, linked to overactivity of the hypothalamic-pituitary-adrenal axis.
- A 66-year-old woman exhibited symptoms such as weakness, weight loss, and poorly controlled hypertension, which led to the discovery of pheochromocytoma, a tumor that causes hormone overproduction, upon further testing.
- After undergoing surgery to remove the tumor and receiving supportive treatment, her symptoms improved significantly, confirming the diagnosis of PCS rather than traditional Cushing's syndrome.
The diagnostic value of prolactin adjustment in bilateral inferior petrosal sinus sampling for differentiating Cushing's disease from the ectopic ACTH syndrome: a systematic review and meta-analysis.

Obesity Research Center, Research Institute for Endocrine Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
Background: Adrenocorticotropin (ACTH)-dependent Cushing's syndrome can arise from a pituitary tumour (Cushing's disease) or an ectopic ACTH-secreting tumour, making precise differentiation essential for effective treatment. Bilateral inferior petrosal sinus sampling (BIPSS) is the gold standard for this differentiation, but false-negative results can limit its accuracy. Adding prolactin (PRL) measurement to BIPSS has been proposed to improve diagnostic precision.

Purpose: Bilateral inferior petrosal sinus sampling (BIPSS) with corticotropin-releasing hormone (CRH) was the gold standard for distinguishing Cushing disease (CD) from ectopic ACTH secretion (EAS). CRH, however, is no longer available.
Objective: To assess the reliability of BIPSS with desmopressin to differentiate CD from EAS.
