AIM: We aimed to compare the performance of nine adrenal steroids in confirming the correct catheter position during adrenal venous sampling (AVS) without cosyntropin in patients with primary hyperaldosteronism. MATERIALS & METHODS: A successful adrenal vein catheterization without cosyntropin was defined as the ratio of steroids from adrenal to peripheral veins being >3:1. AVS samples from four patients with primary hyperaldosteronism were analyzed. RESULTS: Compared with the mean ratio of cortisol without cosyntropin, the ratios of 11-deoxycortisol (p = 0...

PURPOSE: The appropriate cosyntropin dose during cosyntropin stimulation tests remains uncertain. We conducted a prospective, randomized pilot study to compare 1 μg IV low dose cosyntropin test, 25 μg IM medium dose cosyntropin test, and 250 μg IM standard dose cosyntropin test to evaluate secondary adrenal insufficiency. Insulin tolerance test was used as the gold standard. METHOD: The study included patients with hypothalamic/pituitary disease (n  = 10) with at least one pituitary axis deficiency other than ACTH deficiency and controls (n  = 12)...

CONTEXT: ACTH stimulation testing is the current standard for the assessment of primary and secondary adrenal insufficiency (AI). We aimed to investigate the value of basal cortisol level for prediction of AI. METHODS: We retrospectively analyzed 804 consecutive patients who had high-dose (250μg, HDT) or low-dose (1μg, LDT) ACTH testing as part of their diagnostic work-up. Site-specific cut-off levels for AI were <550 in HDT and <500nmol/L in LDT, respectively...

For identification of potentially surgically curable primary aldosteronism, guidelines recommend use of adrenal vein sampling (AVS) that requires selective catheterization of both adrenal veins as verified by using the cortisol-derived selectivity index. Unfortunately, bilaterally selective studies are not obtained under unstimulated conditions in a proportion of the cases ranging between 15% and 50% depending on the cutoff used. We therefore investigated whether 17-α-hydroxyprogesterone and androstenedione, which showed a higher step-up between adrenal vein and inferior vena cava blood than cortisol, can ascertain selectivity when cortisol failed to do so...

Congenital adrenal hyperplasia is a group of autosomal recessive disorders encompassing enzyme deficiencies in the adrenal steroidogenesis pathway that lead to impaired cortisol biosynthesis. Depending on the type and severity of steroid block, patients can have various alterations in glucocorticoid, mineralocorticoid, and sex steroid production that require hormone replacement therapy. Presentations vary from neonatal salt wasting and atypical genitalia, to adult presentation of hirsutism and irregular menses...

PURPOSE: Studies on 1 μg low-dose test showed that among 1 μg cosyntropin samples pushed through long IV plastic tubing, some adrenocorticotropic hormone dosage was not recovered, and in healthy volunteers it provided subnormal cortisol responses. The aim of the current study is to assess whether there is any loss in adrenocorticotropic hormone 1-24 concentration when pushed through a short plastic tube, and to assess serum and salivary cortisol responses in low-dose test among healthy volunteers, using a similar short plastic tube vs...

Phaeochromocytoma localisation is generally reliably achieved with modern imaging techniques, particularly in sporadic cases. On occasion, however, there can be diagnostic doubt due to the presence of bilateral adrenal abnormalities, particularly in patients with mutations in genes predisposing them to the development of multiple phaeochromocytomas. In such cases, surgical intervention is ideally limited to large or functional lesions due to the long-term consequences associated with hypoadrenalism. Adrenal venous sampling (AVS) for catecholamines has been used in this situation to guide surgery, although there are few data available to support diagnostic thresholds...

OBJECTIVE: The definition of normal adrenal function in critically ill patients remains controversial, despite a large body of literature. We review the clinical presentation, diagnosis, and treatment of adrenal insufficiency in critically ill patients and discuss the authors' personal approach to patient management. METHODS: Extensive literature review, guidelines from professional societies, and personal experience. RESULTS: A decrease in cortisol breakdown rather than an increase in cortisol production has been suggested as the main contributor to elevated cortisol levels in critically ill patients...

PURPOSE OF REVIEW: Adrenal insufficiency in pregnancy, although relatively rare, has significant clinical implications on both maternal and fetal outcomes. Hypothalamo-pituitary-adrenal axis dynamics and physiological changes are complex, thus diagnosis and management of adrenal insufficiency in pregnancy remain challenging. RECENT FINDINGS: Studies consistently demonstrate a rise in total serum cortisol with pregnancy, but less data are available on free cortisol levels...

BACKGROUND: Although short-term use (≤2 months) of atomized topical nasal steroids has been shown to be safe and effective, the long-term safety has yet to be demonstrated. The aim of this study was to determine the impact of long-term topical budesonide treatment via the mucosal atomization device (MAD) on the hypothalamic-pituitary-adrenal axis (HPAA) and intraocular pressure (IOP). METHODS: A cross-sectional study of patients with chronic rhinosinusitis (CRS), with or without nasal polyposis, managed with daily nasal budesonide via MAD was conducted at a tertiary rhinology center...

BACKGROUND: Hypothalamic-pituitary-adrenal (HPA) axis dysfunction may be partially responsible for the hemodynamic instability experienced by infants after cardiopulmonary bypass (CPB). We report the full spectrum of the HPA response surrounding CPB for infant congenital cardiac surgery. METHODS: We enrolled 84 infants who received 1 mg/kg of dexamethasone before initiation of CPB. Total cortisol (TC), free cortisol (FC), adrenocorticotropic hormone (ACTH), and corticosteroid-binding globulin (CBG) were measured at 3 time points: immediately before CPB (TP1), on intensive care unit arrival (TP2), and at 24 hours after surgery (TP3)...

Allostatic load from both environmental stressors and persistent glucocorticoid secretion has been associated with disease severity in alcohol dependence. Heightened relapse risk and/or drinking severity, in particular, may be a reaction to alcohol- and withdrawal-induced changes in physiological stress response systems coupled with ongoing life stress, although their shared contributions upon drinking severity have not been assessed. To investigate the combined contribution of hypothalamic-pituitary-adrenal (HPA) reactivity and environmental stressors (e...

OBJECTIVE: Difficulty to recognize or canulate the right adrenal vein is the most frequent cause of adrenal venous sampling (AVS) failure. We aimed to assess multinomial regression modeling (MRM) of peripheral and left adrenal vein samplings to detect lateralization of aldosterone secretion when the right AVS is missing. METHODS: Simultaneous bilateral AVS samplings were performed before (basal) and after intravenous cosyntropin injection in 188 consecutive patients between December 1989 and September 2015...

Cats with cholestatic liver disease experience significant morbidity and mortality when they undergo invasive procedures under anesthesia. Although inadequate adrenal response might account for these outcomes, adrenal function in cats with cholestatic liver disease has not been documented, to our knowledge. The goal of our study was to describe adrenal function in these cats. Twenty-seven cats with a serum bilirubin >230 µmol/L (3 mg/dL) and serum alanine aminotransferase >2 times the upper limit of normal had pre- and 60-min post-adrenocorticotropic hormone (ACTH) cortisol analysis after administration of 5 µg/kg cosyntropin intravenously...

BACKGROUND: Septic shock is a major healthcare problem. Adrenal insufficiency (AI) in children with septic shock is a recognized complication, yet is controversial regarding its management and effect on mortality. According to the current guidelines, children with risk factors for AI should receive a stress dose of steroids in step 3 of treatment. This study aimed to evaluate and compare early corticosteroid therapy with the traditional use of steroids among pediatric septic shock patients...

Primary adrenal lymphoma is an extremely rare condition. We describe a case of bilateral adrenal lymphoma in a man aged 55 years who was admitted to our hospital. He had a 3-month history of left flank pain, nausea and vomiting with weight loss. A CT scan at a private hospital revealed bilateral large adrenal masses; the patient was referred to our centre based on these findings. He was evaluated for pheochromocytoma by an endocrinology team; however, all findings were negative. In addition, a cosyntropin stimulation test indicated adrenal insufficiency...
