BACKGROUND: Pentraxin 3 (PTX3) is an acute-phase glycoprotein, which is increased in patients with cardiovascular disease (CVD) and considered as a predictor of CVD in the general population. Both functional and nonfunctional adrenal tumors are associated with a higher risk of cardiovascular events and mortality. We aimed to investigate plasma PTX3 levels in patients with functioning and nonfunctioning adrenal tumors and to determine its relationship with cardiovascular risk factors. MATERIAL AND METHODS: Twenty-one patients with functional adrenal tumors (11 pheochromocytomas, 9 Cushing's Syndrome and 1 primary hyperaldosteronism), 28 patients with non-functional adrenal incidentilomas, and 40 healthy controls were enrolled in the study...

BACKGROUND: Treatment alternatives for persistent and recurrent Cushing's disease (CD) include pituitary surgical reintervention, radiotherapy, pharmacotherapy and bilateral adrenalectomy (BA). The decision of which of these alternatives is better suited for the individual patient rests on clinical judgment and the availability of resources. OBJECTIVE: To evaluate the long-term efficacy of the different secondary interventions for persistent and recurrent Cushing's disease...

Objectives/Hypotheses Functioning pituitary adenomas may produce endocrinopathies such as acromegaly and Cushing syndrome. Both conditions lead to characteristic anatomic variations as a result of hormonally induced abnormal soft tissue deposition. We evaluate the anatomic differences between acromegalics and Cushing disease patients and compare these dimensions to controls. Design Radiographic review of preoperative magnetic resonance images (MRI) of the pituitary gland. Setting Tertiary academic medical center...

REVIEW
M Poddar, Y Chetty, V T Chetty
Obesity is a chronic, relapsing medical condition that results from an imbalance of energy expenditure and consumption. It is a leading cause of preventable illness, disability and premature death. The causes of obesity are multifactorial and include behavioural, socioeconomic, genetic, environmental and psychosocial factors. Rarely are endocrine diseases, e.g., hypothyroidism or Cushing's syndrome, the cause of obesity. What is less understood is how obesity affects the endocrine system. In this review, we will discuss the impact of obesity on multiple endocrine systems, including the hypothalamic-pituitary axis, changes in vitamin D homeostasis, gender steroids and thyroid hormones...

Cushing's syndrome (CS) is a rare disease caused by a chronic excess of cortisol. Hypercortisolaemia may affect reproductive system leading to infertility in women. However, some of the patients remain fertile, although pregnancy is uncommon. In our report, we describe the case of a 31-years old woman suffering from hypertension, oligomenorrhea, easy bruising, muscle weakness and elevated levels of cortisol. During hospitalization, high level of serum cortisol with stiff diurnal rhythm and undetectable plasma ACTH concentration were found...

PURPOSE: Low plasma corticotropin is considered a useful parameter for the diagnosis of subclinical hypercortisolism in patients with an adrenal incidentaloma. However, immunoassays are vulnerable to interference from endogenous antibodies. In this study, subjects who underwent Hypothalamus-pituitary-adrenal axis evaluation for the assessment of subclinical hypercortisolism were evaluated. The objective of the study was to ascertain whether antibody interference in corticotropin immunoassay affected the diagnostic work-up and clinical decisions...

BACKGROUND: The treatment of hypercortisolism for patients with bilateral adrenal disease (BAD) is controversial. Bilateral total adrenalectomy results in permanent hypocortisolaemia requiring lifelong steroid replacement. A more conservative surgical approach, with less than bilateral total adrenalectomy (leaving functional adrenal tissue either unilaterally or bilaterally), represents an alternative option; however, long-term outcome or recurrence data are limited. We report our experience with the surgical management of hypercortisolism caused by BAD...

Previous studies reported a higher prevalence of venous-thromboembolic events among patients with Cushing disease (CD) compared to those with ACTH-independent Cushing syndrome (CS) from adrenal sources. The objective of the current study was to evaluate the coagulation profile of patients with CS from different etiologies. A prospective observational study was conducted at a clinical research center. The study included adult patients admitted for evaluation of suspected CS (n=85), that were divided into 3 groups: CD (n=22), ACTH-independent CS from an adrenal tumor/hyperplasia (adrenal CS, n=21), and a control group consisting of subjects with negative screening for CS (rule-out CS, n=42)...
