Martina Zahradnicka, Frantisek Saudek, Kvetoslav Lipar, Jelena Skibova
BACKGROUND: Low dehydroepiandrosterone sulfate (DHEAS) levels and a high cortisol/DHEAS ratio are associated with higher mortality in elderly, dialyzed, and immunocompromised patients. The role of these hormones in patients with hypoglycemia unawareness (hypo) or in pancreas or islet recipients treated by glucocorticoid-free immunosuppressive regimen (IS) has not been studied. OBJECTIVE: The aim of this study was to determine the effects of IS and of recurrent hypoglycemia on DHEAS and adrenocorticotropic hormone (ACTH) levels in patients with type-1 diabetes (T1DM)...

Advances in the management of traumatic brain injury, subarachnoid haemorrhage and intracranial tumours have led to improved survival rates and an increased focus on quality of life of survivors. Endocrine sequelae of the acute brain insult and subsequent neurosurgery, peri-operative fluid administration and/or cranial irradiation are now well described. Unrecognized acute hypopituitarism, particularly ACTH/cortisol deficiency and diabetes insipidus, can be life-threatening. While hypopituitarism may be transient, up to 30% of survivors of TBI have chronic hypopituitarism, which can diminish quality of life and hamper rehabilitation...

BACKGROUND: Adrenal corticomedullary mixed tumours are very rare. Its mechanism is rarely reported. Here we report the first case of a corticomedullary mixed tumour resembling a "small adrenal gland" with distinct arrangement of the cortical and medullary layers. We further hypothesize regarding the tumorigenic mechanism of this tumour. CASE PRESENTATION: A 58-year man had been diagnosed with diabetes and hypertension for 3 years. His 24-h urine vanillylmandelic acid (VMA) levels were slightly elevated...

BACKGROUND: Role of brain renin angiotensin system (RAS) is well understood and various clinical studies have proposed neuroprotective effects of ARB's. It is also assumed that diabetic depression is associated with activation of brain RAS, HPA axis dysregulation and brain inflammatory events. Therefore, the present study was designed to investigate the antidepressant effect of low dose telmisartan (TMS) in diabetes induced depression (DID) in rats. METHODS: Diabetes was induced by injecting streptozotocin...

James Findling, Hershel Raff
Endogenous hypercortisolism (Cushing syndrome) usually implies the presence of a pathologic condition caused by either an ACTH-secreting neoplasm or autonomous cortisol secretion from a benign or malignant adrenal neoplasm. However, sustained or intermittent hypercortisolism may also accompany many medical disorders that stimulate physiologic/non-neoplastic activation of the HPA axis (formerly known as pseudo-Cushing syndrome); these two entities may share indistinguishable clinical and biochemical features...

Importance: Pituitary adenomas may hypersecrete hormones or cause mass effects. Therefore, early diagnosis and treatment are important. Observations: Prevalence of pituitary adenomas ranges from 1 in 865 adults to 1 in 2688 adults. Approximately 50% are microadenomas (<10 mm); the remainder are macroadenomas (≥10 mm). Mass effects cause headache, hypopituitarism, and visual field defects. Treatments include transsphenoidal surgery, medical therapies, and radiotherapy...

There is little data documenting cortisol levels in children with diabetic ketoacidosis (DKA), despite the fact that untreated adrenal insufficiency (AI) could worsen the outcome of DKA. In this cross-sectional study, we assessed serum cortisol levels in 28 children with DKA and new onset type 1 diabetes mellitus evaluated at our center over a 5-year period. Average duration of diabetes-related symptoms was positively associated with age ( P = .002), and significantly lower hemoglobin A1c levels were observed in the youngest children...

BACKGROUND: Hypokalemia is a common clinical disorder caused by a variety of different mechanisms. Although the most common causes are diuretic use and gastrointestinal losses, elevated cortisol levels can also cause hypokalemia through its effects on the renin-angiotensin-aldosterone system. Cushing's syndrome refers to this general state of hypercortisolemia, which often manifests with symptoms of generalized weakness, high blood pressure, diabetes mellitus, menstrual disorders, and psychiatric changes...

Background Allostatic load (AL) is an index of multi-system physiological "wear-and-tear," operationalizing emergent chronic disease risk and predicting morbidity and mortality. AL has been proposed as an organizing framework for studying pregnancy outcomes and additional AL biomarkers for the study of maternal health would be valuable. Objectives To test whether adverse perinatal outcomes are associated with postpartum AL and if including vitamin D deficiency (serum 25(OH)D < 20 ng/ml) as an additional marker of postpartum AL increases the association...

An 18-year-old female ringette and basketball player presented to our sport concussion clinic 27 months after concussion with fatigue, headache, exercise intolerance, polyuria, nocturia, and difficulties concentrating. Her history was remarkable for 4 previous concussions. Her neurologic examination was normal. Neuroendocrine screen including thyroid function, morning cortisol, glucose, and insulin-like growth factor-1 (screening test for growth hormone deficiency) were normal. Further testing for growth hormone deficiency with an insulin hypoglycemia test revealed severe growth hormone deficiency...

Conflicting data have been published on the effects of aldosterone excess on glucose metabolism. Specifically, there are limited data on whether adrenalectomy in patients with aldosterone-producing adenomas (APA) can improve glucose metabolism. In this study we evaluated changes in glucose metabolism, before and after surgery for APA. The subjects were 61 patients treated with unilateral adrenalectomy, localized by adrenal venous sampling. A 75g-oral glucose tolerance test (OGTT) was performed before and 1 year after adrenalectomy...

In diabetes, glucocorticoid secretion increases secondary to hyperglycemia and is associated with an extensive list of disease complications. Levels of cortisol in humans, or corticosterone in rodents, are usually measured as transitory biomarkers of stress in blood or saliva. Glucocorticoid concentrations accumulate in human or animal hair over weeks and could more accurately measure the cumulative stress burden of diseases like chronic diabetes. In this study, corticosterone levels were measured in hair in verified rodent models of diabetes mellitus...

OBJECTIVE: Since metabolic syndrome shares several clinical features with hypercortisolism, it was hypothesised that genes altering individual glucocorticoid (GC) sensitivity might be implicated in pathogenesis of obesity and its adverse outcomes. FKBP5 gene encodes a chaperon protein in the GC receptor (GR) complex, which modulates steroid action upon target genes. Its functional variant, rs1360780, may enhance FKBP5 gene transcription, affect GR signalling and thereby influence the hypothalamo-pituitary-adrenal axis...

Optimism is thought to be beneficial for health, and these effects may be mediated through modifications in psychophysiological stress reactivity. Type 2 diabetes (T2D) is associated with reduced cardiovascular responses to stress and heightened cortisol over the day. This study assessed the relationships between optimism, stress responsivity, and daily cortisol output in people with T2D. A total of 140 participants with T2D were exposed to laboratory stress. Heart rate (HR), systolic (SBP), diastolic blood pressure (DBP), and cortisol were measured throughout the session...

BACKGROUND: Regulation of hepatic glucose production has been a target for antidiabetic drug development, due to its major contribution to glucose homeostasis. Previous pre-clinical study demonstrated that peripheral electrical stimulation (PES) may stimulate glucose utilization and improve hepatic insulin sensitivity. The aim of the present study was to evaluate safety, tolerability, and the glucose-lowering effect of this approach in patients with type 2 diabetes (T2DM). METHODS: Twelve patients with T2DM were recruited for an open label, interventional, randomized trial...

AIMS: Hypoglycemia is the major limiting factor in achieving optimal glycemic control in people with type 1 diabetes (T1DM), especially intensively treated patients with impaired glucose counterregulation during hypoglycemia. Naloxone, an opiate receptor blocker, has been reported to enhance the acute counterregulatory response to hypoglycemia when administered intravenously in humans. The current study was undertaken to investigate if the oral formulation of the long acting opiate antagonist, naltrexone, could have a similar effect, and thus might be useful therapeutically in T1DM patients with a high risk for hypoglycemia...
