High prevalence of subclinical hypercortisolism in patients with bilateral adrenal incidentalomas: implications to management

Vassiliadi Dimitra , Ntali Georgia , Vicha Eirini , Tsagarakis Stylianos

Although the prevalence of subclinical hypercortisolism (SH) in unilateral incidentalomas (UI) has been extensively reported, patients with bilateral incidentalomas (BI) have not been thoroughly investigated. Moreover, the management of BI poses great dilemmas if surgery is considered, since bilateral adrenalectomy leads to life-long replacement. In the present study, we aimed to describe the characteristics of patients with BI in comparison to their unilateral counterparts. W...

Excessive bilateral adrenal hyperplasia associated with aldosterone synthase (CYP11B2) deficiency

Diamantopoulos Aristidis , Mourelatos Panagiotis , Sertedaki Amalia , Botoula Efthimia , Vassiliadi Dimitra , Tsagarakis Stylianos

Introduction: Congenital adrenal hyperplasia (CAH) encompasses a group of enzymatic defects in cortisol biosynthesis resulting in adrenal hyperplasia through chronic compensatory ACTH stimulation. Aldosterone synthase deficiency, however, is associated with normal cortisol secretion and there are no reports on whether it may be associated with adrenocortical hyperplasia.Case Presentation: A 37-year-old, Greek female was referred for further investigation...

Bone metabolism and bone mass density following successful treatment of catecholamine secreting tumors

Kardalas Efstratios , Ntali Georgia , Mouchtouris Panagiotis , Papachristou Aglaia , Lavrentaki Aikaterini , Tsagarakis Stylianos

Introduction: Pheochromocytomas and paragangliomas(PPGLs) are catecholamine-secreting tumors. Catecholamine excess contributes to bone resorption and secondary osteoporosis. PPGLs are treated surgically but limited data exists on the subsequent effect on bone status.Aim: To evaluate bone metabolism(BM) and bone mass density(BMD) before and after successful surgery of PPGLs.Methods: A retrospective study on (BM) of (PPGLs) patients ...

Validation of 24-hour human adrenal steroid rhythms measured by ULTRADIAN interstitial automated microdialysis: Comparison with plasma

Upton Thomas , Methlie Paal , Russell Georgina , Henne Nina , Tsagarakis Stelios , Kampe Olle , Lightman Stafford , Husebye Eystein

Background: Hormones oscillate in circadian and ultradian rhythms. Consequently, single time point measurements are very difficult to interpret. To address this, we developed an automated system of 24-hour ambulatory microdialysis. This allows measurement of free hormone concentrations in subcutaneous interstitial fluid collected while participants continue normal daily activities. To validate the technique for adrenal steroid hormones, we simultaneously sampled interstitial f...

Considerable delays to achieve adequate control in treating patients with acromegaly

Tzanela Marinella , Karapanou Olga , Giatra Christianna , Botoula Efstathia , Tiaka Elisabeth , Anastasia Lambraki , Tsagarakis Stylianos

Acromegaly is a rare disease that leads to considerable morbidity and mortality, both reversible by adequate control of the disease. However, patients that could be adequately controlled confront delays in achieving treatment targets. The aim of the present study was to estimate the time to disease control after diagnosis and the reason leading to control delays. We retrospectively studied 119 acromegalic patients (aged 46.4±12.5; 71 females). Following appropriate treatm...

24-hour adrenal steroid rhythms are readily detected by ULTRADIAN automated ambulatory microdialysis in man

Upton Thomas , Methlie Paal , Russell Georgina , Tsagarakis Stelios , Kampe Olle , Lightman Stafford , Husebye Eystein

Background: Hormones oscillate in circadian and ultradian rhythms. Single time point samples are difficult to interpret and high frequency measurements are time consuming, expensive and invasive. We developed a minimally invasive technique of ambulatory, automated microdialysis. This allows frequent 24-hour sampling of interstitial fluid while participants continue normal daily activities.Methods: Healthy volunteers (age 18–68, no regular medication...

Functional muscle capacity and daily physical activity deficits in patients with endogenous Cushing's syndrome

Assimakopoulou A , Louvaris Z , Balomenaki M , Chynkiamis N , Tzanela M , Vogiatzis I , Tsagarakis S

Cushing’s syndrome (CS) is a disease entity that through hypercortisolism affects all body’s tissues leading to increased morbidity, decreased quality of life and mortality. Muscles are among the tissues primarily affected. However, data on the impact of endogenous hypercortisolism on functional muscle capacity and daily physical activity levels are scarce. We studied 23 subjects with endogenous CS (mean age: 40.73±2.17 years) and 22 healthy aged and sex matched...

Tissue cortisol vs lipolysis in ICU patients

Ilias Ioannis , Vassiliadi Dimitra , Theodorakopoulou Maria , Nikitas Nikitas , Tzanela Marinela , Apollonatou Sofia , Tsagarakis Stylianos , Dimopoulou Ioanna

Introduction: The interplay of cortisol (F) and adipose tissue is complex and in many aspects is still obscure. Plasma F has been shown to be positively associated with lipolysis.Aim: To study in adipose tissue indices of lipolysis vs tissue F with microdialysis (MD).Subjects and methods: We studied 46 mechanically ventilated patients with a diagnosis of septic/non-septic shock, systemic inflammatory response syndrome or s...

The role of late-night salivary cortisol measurement in the diagnosis of subclinical hypercortisolism in patients with adrenal incidentalomas

Perogamvros I , Tzanela M , Koletti A , Tsirona S , Memi E , Tsagarakis S

The diagnosis of subclinical hypercortisolism (SH) is a challenging issue, especially as the high prevalence of adrenal incidentalomas (AI) is increasingly recognized. The diagnosis of subclinical hypercortisolism relies on a combination of tests that include overnight (ODST) or low dose dexamethasone suppression (LDDST), plasma ACTH, and 24-h urinary free cortisol (UFC). Late night salivary cortisol (LNSC) has been successfully used in the diagnosis of Cushing’s syndrome...

Effect of treatment outcome on co-morbidities of Cushing's disease

Assimakopoulou Athina , Tzanela Marinella , Palimeri Sotiria , Karapanou Olga , Botoula Efi , Tsagarakis Stylianos

Generously supported by IPSEN)-->Endogenous hypercortisolism leads to increased morbidity and mortality. As Cushing’s disease (CD) is a rare disorder, data on co-morbidities outcome after current treatment interventions are scarce.We studied 78 patients with CD (67 females, 11 males, mean age 42.2±1.4 years), with a follow up of 90.8±7.8 months. All patients underwent transsphenoidal surgery (TSS...
