Adrenal insufficiency is divided into three types based on the etiology of its development. In primary adrenal insufficiency, pathology resides in end-organ failure at the level of the adrenal cortex, while in secondary and tertiary adrenal insufficiency, impairment rests in the pituitary gland and hypothalamus, respectively. Regardless of etiology, adrenal insufficiency results in a hypocortisolemic condition. While the relationship between neuropsychiatric symptoms, especially psychosis, and hypercortisolemia has been extensively documented, the development of hypocortisolemia-induced psychosis is less common...

The French endocrinology society (SFE) and the French pediatric endocrinology society (DFSDP) have drawn up recommendations for the management of primary and secondary adrenal insufficiency in the adult and child, based on an analysis of the literature by 19 experts in 6 work-groups. A diagnosis of adrenal insufficiency should be suspected in the presence of a number of non-specific symptoms except hyperpigmentation which is observed in primary adrenal insufficiency. Diagnosis rely on plasma cortisol and ACTH measurement at 8am and/or the cortisol increase after synacthen administration...

Immune checkpoint Inhibitors are new immunomodulatory treatments that have proven their anti-tumor efficacy in several advanced cancers. Nevertheless, their use has paved the way for multiple immunological adverse effects that affect many systems and organs including endocrine glands such as the pituitary, thyroid, adrenal and pancreas. Hypophysitis is the most common complication of anti-CTLA-4 monoclonal antibodies, while anti-PD-1 and anti-PD-L1 antibodies cause more thyroid complications. Adrenal insufficiency and type 1 diabetes are relatively less common...

Hypogonadism is a well-known complication in males with chronic liver diseases. However, the consequences of chronic hepatopathies on female reproductive capacities have received relatively little attention. The present study evaluates the effect of chronic obstructive jaundice on the ovary of adult cycling rats. Estrous cyclicity was monitored to check the functional status of the hypothalamic-pituitary-ovarian axis. Ovarian changes were assessed using histomorphometric, immunohistochemical, and ultrastructural techniques...

Leptin actions at the pituitary level have been extensively investigated in mammalian species, but remain insufficiently characterized in lower vertebrates, especially in teleost fish. Prolactin (PRL) is a pituitary hormone of central importance to osmoregulation in fish. Using goldfish as a model, we examined the global and brain-pituitary distribution of a leptin receptor (lepR) and examined the relationship between expression of lepR and major pituitary hormones in different pituitary regions. The effects of recombinant goldfish leptin-AI and leptin-AII on PRL mRNA expression in the pituitary were further analysed, and the mechanisms underlying signal transduction for leptin-induced PRL expression were determined by pharmacological approaches...

Focal incidental uptake, with or without CT abnormalities, is a common finding on FDG PET/CT and evidence based management for this type of uptake is lacking. This article reviews the evidence on focal incidental uptake including the incidence of malignancy, differential diagnosis and imaging criteria which can be used to further characterise it. The article focusses on PET rather than CT criteria. The strength of the evidence base is highly variable ranging from systematic reviews and meta-analyses to a virtual absence of evidence...

The daily rhythm of the hypothalamo-pituitary-adrenal (HPA) axis is regulated by the central clock in the suprachiasmatic nucleus. Cortisol, a glucocorticoid, acts as a secondary messenger between the central clock and the peripheral tissues. Changes in clock time, as seen in shift workers, alters the HPA axis and results in metabolic disturbances associated with ill health. Depression, anorexia nervosa and obstructive sleep apnoea, are associated with cortisol rhythm phase shifts and increased cortisol exposure...

Systems biology methods, such as transcriptomics and metabolomics, require large numbers of small model organisms, such as zebrafish embryos. Manual separation of mutant embryos from wild-type embryos is a tedious and time-consuming task that is prone to errors, especially if there are variable phenotypes of a mutant. Here we describe a zebrafish embryo sorting system with two cameras and image processing based on template-matching algorithms. In order to evaluate the system, zebrafish rx3 mutants that lack eyes due to a patterning defect in brain development were separated from their wild-type siblings...

Cortisol levels in bodily fluids represent a useful index for pituitary-adrenal function, and thus practical anti-cortisol antibodies are required. We have studied "antibody-breeding" approaches, which involve in vitro evolution of antibodies to improve their antigen-binding performances. Here, we produced an antibody fragment to measure serum cortisol levels with over 30-fold enhanced affinity after single mutagenesis and selection steps. A mouse anti-cortisol antibody, Ab-CS#3, with insufficient affinity for practical use, was chosen as the prototype antibody...

REVIEW

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...

Symptoms of hypopituitarism are usually chronic and nonspecific, but rarely the disease can have acute and life threatening manifestations. We report a 53 years old female with a pituitary adenoma that was admitted to our hospital because of syncope. The electrocardiogram showed sinus bradycardia with a prolonged QT interval. Frequent runs of non-sustained polymorphic ventricular tachycardia were noted on telemetry. The patient had a history of severe acute headaches in the previous days and laboratory tests revealed severe secondary hypothyroidism, adrenal insufficiency and a decrease in pituitary hormones...

AIM: To determine the dominant predictive factors of postoperative visual recovery for patients with pituitary adenoma. METHODS: PubMed, Google Scholar, Web of Science and Cochrane Library were searched for relevant human studies, which investigated the prediction of the postoperative visual recovery of patients with pituitary adenoma, from January 2000 to May 2017. Meta-analyses were performed on the primary outcomes. After the related data were extracted by two independent investigators, pooled weighted mean difference (WMD) and odds ratio (OR) with 95% confidence interval (CI) were estimated using a random-effects or a fixed-effects model...

A male neonate was born at 41 weeks of gestation with a birth weight of 3320 g. Artificial respiratory management was required due to respiratory disturbance 1 h after birth, and subsequently catecholamine-refractory low cardiac output-induced shock occurred. Severe combined pituitary hormone deficiency (CPHD) was considered based on the presence of his respiratory disturbance, hypoglycemia and micropenis. After hydrocortisone (HDC) administration, circulatory dynamics rapidly improved. Brain magnetic resonance imaging (MRI) showed aplasia of the anterior pituitary gland and ectopic posterior gland...

A diagnosis of adrenal insufficiency should be suspected in the presence of a number of non-specific symptoms (fatigue, anorexia, weight loss, hypotension, hyponatremia and hyperkalemia amongst adrenal causes of insufficiency). The diagnosis should be considered in case of pituitary disease or a state of shock. Treatment should be commenced immediately without waiting for confirmation from biochemical tests, which rely on cortisol level at 8am (expected to be low) and on ACTH level (expected to be high in the case of primary adrenal insufficiency)...

Hypogonadal men may experience intense vasomotor symptoms, and vasomotor sweating can occasionally be associated with profound fluid losses. We describe a 37-year-old male, who exhibited persistent hypovolaemic hypernatraemia that was challenging to treat despite a continuous high fluid input (>4-5 L/day). He was noted to have drenching sweats and normochromic anaemia. He had recent traumatic head injury, which resulted in neurocognitive dysfunction, so pituitary function tests were done which showed primary hypogonadism...

Epidermoid cyst (EC) or cholesteatoma is a benign tumor, often of congenital origin, occurring in the sub-arachnoidian spaces. Its treatment is based on surgery. We report the case of a 38 year-old patient presenting with progressive intracranial hypertension syndrome associated with anterior pituitary insufficiency signs of the corticotropic, thyrotropic, gonadotropic axis occurring 1 year before. Brain MRI showed a craniopharyngioma. Anatomopathologic evaluation of the specimen showed epidermoid cyst.

Although maternal nurturing behavior is extremely important for the preservation of a species, our knowledge of the biological underpinnings of these behaviors is insufficient. Here we show that the degree of a mother's nurturing behavior is regulated by factors present during her own fetal development. We found that Cin85-deficient (Cin85(-/-)) mother mice had reduced pituitary hormone prolactin (PRL) secretion as a result of excessive dopamine signaling in the brain. Their offspring matured normally and produced their own pups; however, nurturing behaviors such as pup retrieval and nursing were strongly inhibited...

A 63-year-old Japanese woman with advanced lung adenocarcinoma developed isolated adrenocorticotropin deficiency caused by immune checkpoint inhibitor (ICI)-related hypophysitis following 8 months of nivolumab therapy. Prompt corticosteroid replacement therapy effectively relieved her secondary adrenal insufficiency symptoms and allowed her to pursue nivolumab therapy, which had been effective for the control of lung adenocarcinoma. Human leukocyte antigen (HLA) typing revealed the presence of the DRB1*04:05-DQA1*03:03-DQB1*04:01 haplotype, which is associated with susceptibility to autoimmune polyglandular syndrome with pituitary disorder in the Japanese population...

Background: Adrenal insufficiency (AI) secondary to treatment with glucocorticoids (GCs) is common in patients with inflammatory bowel disease (IBD), but little is known about the relationship between AI and the clinical course in IBD. The aim of the study was to compare the clinical course in IBD patients with normal adrenal function versus patients with subnormal adrenal function. Methods: A retrospective observational study on 63 patients with IBD who had performed a low-dose short Synacthen test (LDSST) (1 μg) immediately (1-7 days) after a standard course of GCs...
