PURPOSE: Silent corticotroph adenomas (SCAs) present clinically as non-functioning adenomas (NFAs) but are immunopositive for adrenocorticotrophic hormone (ACTH) without biochemical and clinical manifestation of hypercortisolism. Pathologic examination of resected NFAs that demonstrate positive ACTH and/or TPIT expression confirms its corticotroph lineage. SCAs comprise up to 20% of NFAs and exhibit a higher rate of recurrence. Studies of molecular mechanisms have generated multiple hypotheses on SCA tumorigenesis, pathophysiology, and growth that as yet remain to be proven...

BACKGROUND: A subnormal cortisol response (30 min level (C30min)<550 nmol/L) to synthetic adrenocorticotrophic hormone/Synacthen test (SDST) in all infants does not necessarily indicate underlying or persistent hypothalamic-pituitary-adrenal axis pathology. METHODS: We retrospectively evaluated the diagnoses and outcomes in 68 infants who had a SDST at age <6 months from 2011 to 2014. RESULTS: 29 (43%) infants had a subnormal SDST...

INTRODUCTION: Sirtuins are NAD dependent class III histone deacetylases. In adrenal cortex mitochondria are able to transform - via nicotinamide nucleotide transhydrogenase (NNT) - NAD into NADPH, which is required for steroidogenesis. These findings suggest that sirtuins expressed in mitochondria, Sirt3, Sirt4 and Sirt5, may be associated with adrenal steroidogenesis. Therefore, the purpose of this study was to characterize the expression of mitochondrial sirtuins (Sirt3-5) in individual compartments of rat adrenal cortex, their developmental regulation and to demonstrate whether their expression is dependent on adrenocorticotrophic hormone (ACTH) and Nampt (nicotinamide phosphoribosyltransferase also known as visfatin/PBEF), the rate-limiting enzyme in the regulation of mammalian NAD synthesis...

Glucocorticoids (GC) induce cardiometabolic risk while atherosclerosis is a chronic inflammation involving immunity. GC are immune suppressors, and the adrenocorticotrophic hormone (ACTH) has immune modulator activities. Both may act in atherothrombotic inflammation involving immune cells (IMNC). Aim. To investigate adhesion and activation surface cell markers (CDs) of peripheral IMNC in endogenous Cushing syndrome (CS) and the immune modulator role of ACTH. Material and Methods. 16 ACTH-dependent CS (ACTH-D), 10 ACTH-independent (ACTH-ID) CS, and 16 healthy controls (C) were included...

BACKGROUND: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a progressive or relapsing and remitting paralysing illness, probably due to an autoimmune response, which should benefit from corticosteroid treatment. Non-randomised studies suggest that corticosteroids are beneficial. Two commonly used corticosteroids are prednisone and prednisolone. Both are usually given as oral tablets. Prednisone is converted into prednisolone in the liver so that the effect of the two drugs is usually the same...

BACKGROUND: Pituitary adenomas are usually considered benign tumours, although some of them can exhibit an aggressive behaviour. Patients with clinically aggressive pituitary adenomas are frequently diagnosed with larger masses, and may present an earlier recurrence (or persistence) after surgery. Our aim was to characterise the clinical, histopathological and radiological features of patients with aggressive pituitary adenoma, in order to correlate their clinical behaviour with the response to treatment plan...

OBJECTIVE: To evaluate if the parameters of hypothalamic-pituitary-adrenal (HPA) axis activity could predict the occurrence and duration of post-surgical hypocortisolism (PSH) in patients with Cushing's syndrome (CS) and with adrenal incidentaloma (AI). METHODS: We studied 80 patients (54 females, age 53.3 ± 11 years), who underwent adrenalectomy for CS (17 patients) or for AI (53 patients). Before surgery, we measured adrenocorticotroph hormone (ACTH), urinary free cortisol (UFC) and serum cortisol after 1 mg dexamethasone suppression test (1 mg-DST) levels...

Cumulative evidence has suggested an association between stress and alcohol self‑administration; however, less is known about the role of traumatic stress in alcohol drinking behavior. It has been reported that cocaine‑ and amphetamine‑regulated transcript (CART) 55‑102 may be involved in mediating stress responses and regulating reward and reinforcement. The aim of the present study was to evaluate the role of CART 55‑102 in alcohol drinking behavior of rats in the presence or absence of traumatic stress...

Background: Neuroendocrine tumours (NETs) are a heterogeneous group of diseases that can originate from any part of the gastrointestinal tract, bronchi, thyroid and pancreas. These tumours may be functioning or not depending on their ability to produce active substances, such as adrenocorticotrophic hormone (ACTH). ACTH-producing pancreatic neuroendocrine tumours are rare, with limited data about effective antitumor therapies. Case Report: A 58-year-old man with a history of type-2 diabetes mellitus and arterial hypertension was diagnosed with Cushing's syndrome (CS) secondary to an ACTH ectopic production from a well-differentiated neuroendocrine tumour of the pancreas metastatic to the liver...

Clinical presentation of hypopituitarism may be variable in the neonate. Symptoms are generally nonspecific, ranging from absent to severe, and even life-threatening, due to adrenocorticotrophic hormone deficiency. Presently described is a case of unexplained respiratory distress and edema in a neonate. Initial screening revealed panhypopituitarism. Respiratory distress improved after replacement treatment with hydrocortisone and thyroxine.

Approximately 30-60% of patients treated with existing antidepressants fail to achieve remission of depressive symptoms leading to Treatment Resistant Depression (TRD). There is an urgent need to develop novel medications, which is highly limited by the non-availability of relevant animal models with good predictive validity. ACTH administration has been shown to result in the resistance to acute and chronic effects of imipramine. However, the pharmacology of the model and the mechanisms contributing to the resistance are not completely understood...

OBJECTIVE: Patients receiving long-term glucocorticoid treatment are at risk of developing adrenal insufficiency during treatment. We investigated the prevalence of prednisolone-induced adrenal insufficiency in the particular clinical situation where patients receive ongoing low-dose (5 mg/day) prednisolone treatment, a dose by itself too low to cover glucocorticoid needs during stress. DESIGN AND METHODS: Cross-sectional study in 42 patients with rheumatoid arthritis (29 women, aged 36-86 years) treated with 5 mg prednisolone/day, who had received prednisolone for ≥6 months (median: 66, range: 6-444 months)...

Inflammation after stroke is the main cause of cerebral ischemia/reperfusion injury. Cascading events after injury can lead to cell death. Heat shock protein 70 and other endogenous injury-signaling molecules are released by damaged cells, which can lead to systemic stress reactions. Protecting the brain through repair begins with the stress-injury-repair signaling chain. This study aimed to verify whether acupuncture acts through this chain to facilitate effective treatment of ischemic stroke. Rat models of cerebral ischemia/reperfusion injury were established by Zea Longa's method, and injury sites were identified by assessing neurological function, 2,3,5-triphenyltetrazolium chloride staining, and hematoxylin-eosin staining...
