Mitotane (o,p'DDD) is established in the adjuvant and advanced stage treatment of adrenocortical carcinoma and counteracts both tumour growth and tumour-related steroid production. Both the adrenal glands and the gonads are steroidogenically active organs and share a common embryogenic origin. Here we describe the effects of mitotane in two patients with metastatic Leydig cell tumour (LCT) of the testes and associated severe androgen excess (serum testosterone 93 and 88 nmol/l, respectively; male reference range 7-27 nmol/L)...

A 64-year-old man was admitted to our hospital for the hormonal evaluation of a right adrenal adenoma. He had been diagnosed with severe proteinuria and hypertension, and antihypertensive treatment was started at the age of 60. His renal function gradually declined, and hemodialysis was begun at the age of 64. Since his blood pressure was uncontrollable and resistant to antihypertensive treatment, an endocrinological examination was performed for an incidental right adrenal mass detected by computed tomography...

Primary adrenal insufficiency (PAI) is a heterogeneous group of clinical and genetic disorders characterized by an impaired production of cortisol and other steroid hormones by the adrenal cortex. Most of the causes of PAI in childhood are inherited and monogenic in origin and are associated with significant morbidity and mortality whenever the diagnosis and treatment is delayed. Therefore, early and accurate diagnosis would allow appropriate management for the patients and more accurate genetic counseling for the family...

Tramadol is a synthetic, centrally acting analgesic. It is the most consumed narcotic drug that is prescribed in the world. Tramadol abuse has dramatically increased in Egypt. Long term use of tramadol can induce endocrinopathy. So, the aim of this study was to analyze the adrenal insufficiency induced by long term use of tramadol in experimental animals and also to assess its withdrawal effects through histopathological and biochemical genetic study. Forty male albino rats were used in this study. The rats were divided into 4 groups (control group, tramadol-treated group, and withdrawal groups)...

There are two problems that needs to be addressed in cases of an adrenal incidentaloma. The first is to decide whether the adrenal mass is benign or malignant, and the second is to determine whether the mass is hormonally active or not. A 17-year-old male was admitted with the complaint of progressive weight gain. Abdominal ultrasonography was performed for elevation in transaminases which revealed a hypoechoic mass located in the left adrenal gland...

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...

Post-traumatic stress disorder (PTSD) occurs following life-threatening events. The activity of the hypothalamic-pituitary-adrenal (HPA) axis, which serves as the first line of defense against stress, is dysfunctional in this disorder. The current study aimed to investigate the role of Crocin in normalizing HPA function in an animal model of PTSD induced by electric foot shock. Rats were treated with Crocin 5 min prior to stress induction. The stimulus was re-introduced after 21 days, and we measured individual behaviors such as sniffing, rearing, grooming, and freezing...

The hypothalamo-pituitary-adrenal (HPA) axis comprises interactions between the hypothalamus, the pituitary and the adrenal glands and its activation results in the release of corticosteroid hormones. Corticosteroids are secreted from the adrenal gland in a distinct 24-h circadian rhythm overarching an ultradian rhythm, which consists of hourly corticosteroid pulses exposing target tissues to rapidly changing steroid levels. On top of these rhythms surges can take place after stress. HPA-axis rhythms promote adaptation to predictable (i...

Hypercortisolism is one of the most commonly diagnosed endocrinopathies in dogs, and new targeted medical treatment options are desirable. Steroidogenic factor-1 (SF-1), an orphan nuclear hormone receptor, is a key regulator of adrenal steroidogenesis, development, and growth. In pituitary-dependent hypercortisolism (PDH), high plasma ACTH concentrations increase the transcriptional activity of SF-1. In adrenal-dependent hypercortisolism, SF-1 expression is significantly greater in dogs with recurrence after adrenalectomy than in those without recurrence...

Ghrelin is the endogenous ligand for the growth hormone secretagogue receptor. We investigated the distribution and morphological characteristics of ghrelin-immunopositive (ghrelin-ip) cells in the African ostrich adrenal gland. We found that the adrenal gland of the African ostrich consisted of three parts: capsule, inter-renal tissue and chromaffin cells. The inter-renal tissue and chromaffin cells interdigitated irregularly. The inter-renal tissue consisted of a peripheral zone and a central inner zone. The peripheral zone could be divided into an outer subcapsular zone and an inner zone...

The skin serves as a window for clinicians to understand, diagnose, and monitor endocrine disease. Dermatologic manifestations of endocrinopathies contribute significantly to an individual's health and quality of life. In this review, we outline various disorders of the hypothalamic-pituitary axis, thyroid gland, pancreas, adrenal gland, and androgen axis as well as hereditary endocrine syndromes. In acromegaly, glycosaminoglycan deposition contributes to a thickening of skin and soft tissue, which manifests as coarsening and enlargement of facial and acral structures...

Secondary adrenal insufficiency can result from insufficient stimulation of the adrenal glands due to inadequate secretion or synthesis of adrenocorticotropic hormone (ACTH). This can be caused by hypopituitarism, central nervous system injury (tumors, radiation, and surgery) or long-term glucocorticoid therapy. Glucocorticoids were introduced in the 1950s, and have been used for their anti-inflammatory and other pharmacological effects, and also as replacement therapy for adrenal insufficiency. However, chronic glucocorticoid use may lead to suppression of the hypothalamic pituitary adrenal axis through negative feedback...
