Tension-type headache (TTH) is the most prevalent primary headache. Chronic TTH (CTTH), the most serious form of TTH, is refractory, with a high socio-economic burden. Research studies have shown patients with migraine often had cognitive impairment, but few studies have focused on the cognition in CTTH patients. In the present study, we assumed that patients with CTTH also have cognitive impairments, which are modulated by the neuroendocrine state. Participants were recruited, including CTTH patients and healthy controls...

Patients with bilateral pheochromocytoma often require an adrenalectomy. Autotransplantation of the adrenal cortex is an alternative therapy that could potentially be performed instead of receiving glucocorticoid replacement following adrenalectomy. Adrenal cortex autotransplantation aims to avoid the side effects of long‑term steroid treatment and adrenal insufficiency. Although the function of the hypothalamo‑hypophysial system is critical for patients who have undergone adrenal cortex autotransplantation, the details of that system, with the exception of adrenocorticotropic hormone in the subjects with adrenal autotransplantation, have been overlooked for a long time...

Centrally acting prolactin has been shown to have anti-stress effects by modulating the activity of the hypothalamic-pituitary-adrenal axis. We tested the hypothesis that prolactin directly targets hypothalamic corticotropin-releasing hormone (CRH) neurons. In situ hybridisation confirmed expression of mRNA encoding the long, but not the short, isoform of the prolactin receptor (PRLR) within the paraventricular nucleus (PVN) of the virgin rat; however, only 6% of CRH neurons expressed long-form Prlr mRNA. Examination of the functional response of CRH neurons to intracerebroventricular prolactin (500 ng) showed that these neurons did not respond with activation of phosphorylated signal transducer and activator of transcription 5 (pSTAT5), a marker of long-form PRLR activation...

BACKGROUND: The hypothalamic-pituitary-adrenal stress axis plays a crucial role in community-acquired pneumonia (CAP), with high cortisol being associated with disease severity and corticosteroid treatment resulting in earlier time to recovery. Our aim in the present study was to compare different glucocorticoid hormones, including cortisol, 11-deoxycortisol, cortisone, and corticosterone, regarding their association with short- and long-term adverse outcomes in a well-defined CAP cohort...

Psychiatric disorders arise due to an interplay of genetic and environmental factors, including stress. Studies in rodents have shown that mutants for Disrupted-In-Schizophrenia-1 (DISC1), a well-accepted genetic risk factor for mental illness, display abnormal behaviours in response to stress, but the mechanisms through which DISC1 affects stress responses remain poorly understood. Using two lines of zebrafish homozygous mutant for disc1, we investigated behaviour and functioning of the hypothalamic-pituitary-interrenal (HPI) axis, the fish equivalent of the hypothalamic-pituitary-adrenal (HPA) axis...

Nivolumab, an anti-programmed death-1 antibody, is a breakthrough treatment for several malignancies. Its specific adverse effects caused by autoimmunity are termed immune-related adverse events, which involve several endocrine dysfunctions. Herein, we report two cases of isolated adrenocorticotropic hormone (ACTH) deficiency induced by nivolumab for the treatment of metastatic malignant melanoma. Case 1 was a 39-year-old man and Case 2 was a 50-year-old woman, both of whom presented with progressive melanoma...

Multiple endocrine neoplasia type 1 (MEN1) syndrome is a relatively rare disease, characterized by the occurrence of multiple endocrine tumors in the parathyroid and pituitary glands as well as the pancreas. Here, we report a case of MEN1 with neuroendocrine tumors (NETs) in the stomach, duodenum, and pancreas. A 53-year-old man visited our hospital to manage gastric NET. Five years prior to his visit, he had undergone surgery for incidental meningioma. His brother had pancreatic nodules and a history of surgery for adrenal adenoma...

Pituitary stalk interruption syndrome (PSIS) is a congenital disease with isolated growth hormone deficiency (GHD) or multiple anterior pituitary hormone deficiencies (MPHD). The typical clinical manifestations of PSIS are growth retardation, hypoglycemia or delayed pubertal development. However, few reports showed cases of PSIS were diagnosed with acute epileptic seizures accompanied by hyponatremia. Here, we report an 18-year-old female presenting with episodes of intermittent seizures for 13 years. The electrolyte examination on many occasions has shown hyponatremia, even as low as 99...

Context: Increased cortisol levels in obesity may contribute to the associated metabolic syndrome. In obesity, the activated innate immune system leads to increased interleukin (IL)-1β, which is known to stimulate the release of adrenocorticotropin hormone (ACTH). Objective: We hypothesised that in obesity IL-1 antagonism would result in downregulation of the hypothalamo-pituitary-adrenal (HPA) axis, leading to decreased cortisol levels. Design and participants: In this prospective intervention study we included 73 patients with obesity (BMI >30kg/m2) and at least one additional feature of the metabolic syndrome...

Bombesin receptor subtype 3 (BRS-3) is an orphan G-protein-coupled receptor. Based on the obese phenotype of male BRS-3-deficient mice, BRS-3 has been considered an attractive target for obesity treatment. Here, we developed a novel selective BRS-3 agonist (Compound-A) and evaluated its anti-obesity effects. Compound-A showed anorectic effects and enhanced energy expenditure in diet-induced obese (DIO)-F344 rats. Moreover, repeated oral administration of Compound-A for 7 days resulted in a significant body weight reduction in DIO-F344 rats...

Glucocorticoids often rise and fall with a variety of external and internal cues and frequently vary among life-history stages. This suggests that changing glucocorticoids may coordinate life-history transitions. To explore this hypothesis, we asked if the time-course of stress-induced glucocorticoid levels differ between two life-history transitions (i.e., spring and fall migration) in female red-sided garter snakes (Thamnophis sirtalis parietalis). We collected non-migratory females from a communal den and migratory females from a road along the migration route and treated them with 4 h of capture stress; plasma corticosterone was measured before, during and after capture stress...

Chronic exposure to stress amplifies locomotor deficits and exacerbates dopamine neuron loss in an animal model for Parkinson's disease. The release of neurotrophic factors such as glial cell-line derived neurotrophic factor (GDNF) and neurotrophin-3 (NT-3) following neuronal injury attenuates exacerbated degeneration of these neurons. In this study, the neurotoxin 6-hydroxydopamine (6-OHDA) was injected unilaterally into the medial forebrain bundle of male Sprague Dawley rats. A subset of these rats was subjected to post-lesion restraint stress after which the effect of exposure to stress on locomotor activity (forelimb akinesia test), neurotrophic factor (GDNF and NT-3) and corticosterone concentration was assessed...

V M Merkulov, T I Merkulova, N P Bondar
Exposure to stress activates the hypothalamic-pituitary-adrenal axis and leads to increased levels of glucocorticoid (GC) hormones. Prolonged elevation of GC levels causes neuronal dysfunction, decreases the density of synapses, and impairs neuronal plasticity. Decreased sensitivity to glucocorticoids (glucocorticoid resistance) that develops as a result of chronic stress is one of the characteristic features of stress-induced psychopathologies. In this article, we reviewed the published data on proposed molecular mechanisms that contribute to the development of glucocorticoid resistance in brain, including changes in the expression of the glucocorticoid receptor (GR) gene, biosynthesis of GR isoforms, and GR posttranslational modifications...

Hypersexual Disorder (HD) defined as non-paraphilic sexual desire disorder with components of compulsivity, impulsivity and behavioral addiction, and proposed as a diagnosis in the DSM 5, shares some overlapping features with substance use disorder including common neurotransmitter systems and dysregulated hypothalamic-pituitary-adrenal (HPA) axis function. In this study, comprising 67 HD male patients and 39 male healthy volunteers, we aimed to identify HPA-axis coupled CpG-sites, in which modifications of the epigenetic profile are associated with hypersexuality...

BACKGROUND: Increased activity of the three major physiological stress systems (immune-inflammatory system, hypothalamic-pituitary-adrenal-axis [HPA-axis], and autonomic nervous system [ANS]) is part of the pathophysiology of various somatic and psychiatric diseases. Oxidative damage is a key mechanism in both ageing and disease. Elucidating the relationship between these stress systems and oxidative damage would contribute to the understanding of the role of physiological stress in disease...
