Glucocorticoid (Gc) excess, either endogenously produced (Cushing’s syndrome) or as a result of exogenous steroid treatment, can cause metabolic disorders such as obesity and hyperglycaemia. The contribution of centrally acting corticosterone in the development of these metabolic disorders is unknown. Gcs regulate the anorexigenic and orexigenic neuropeptides (POMC and AgRP) within the arcuate nucleus of the hypothalamus to modulate energy balance. This study investigated...

Background: Bile acids (BAs) are end-products of cholesterol catabolism, which act as signalling molecules to regulate glucose, lipid and energy metabolism. BAs activate several receptors including the ligand sensitive transcription factor Farnesoid X receptor (FXR) and the membrane G-protein coupled receptor, TGR5. Besides the organs physiologically in contact with BAs, like the gut and liver, BA-receptors are also expressed in cholesterol-rich steroidogenic tissues, such as ...

Introduction: Patients who have diabetes are at risk of complications, both acutely and in the long term. Although care is individualised, it may not be practical to continuously review this on an individual basis. An audit evaluating outcomes is a useful tool to reflect on multidisciplinary team management. We describe how effective use of resources led to better results in a multi-ethnic population.Population: A total of 130 children and young people w...

Background: Neuropsychiatric symptoms and cognitive dysfunction are common in Cushing´s disease (CD), and seem only partly reversible after biochemical remission has been achieved.Aim: To investigate prescription of drugs associated with neuropsychiatric morbidity in a large national cohort of CD patients.Methods: Patients in the Swedish Pituitary Registry, diagnosed with CD between July 2006 and January 2018 were included, <e...

Background: Patients with pituitary tumour live with life-long consequences of their disease. The first year after pituitary surgery represents a time period of symptoms, fear of tumour recurrence, existential concerns as well as extensive medical evaluations and decisions about hormone replacement. To increase wellbeing, a person-centred care practice up to 1 year after pituitary surgery covering self-management support, accessibility and continuity has been implemented and a...

Background: In females, timing of puberty and fertility require estradiol (E2) action at the infantile and late juvenilestages and are tightly influenced by environmental cues. A regulator of intra-ovarian E2 synthesis during reproductive life is the aryl hydrocarbon receptor (AhR). However, its action on E2 synthesis and its capacity to mediate the effect of endocrine disrupting chemicals (EDC)s has not been thoroughly evaluated during the prepubertal period.<p class="abs...

Introduction: Pancreatectomy may be necessary to treat hypoglycaemia due to congenital hyperinsulinism (CHI) following failure of medical management. Post-operative complications including infection and persistent hypoglycaemia have been reported after pancreatectomy, but factors predictive of these have not been recognised.Aims: To investigate if early factors or the time to surgery predict risk of CHI surgical complications and hypoglycaemia in the 6 m...

Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic disease. 5β-reductase (AKR1D1) is highly expressed in human liver where it inactivates steroid hormones and, in parallel, catalyzes a fundamental step in bile acid synthesis. Steroid hormones, including glucocorticoids, as well as bile acids (BAs) are established regulators of metabolic phenotype. We have hypothesized that AKR1D1 plays a crucial regulatory role in hepatic metabolic homeost...

Introduction: Cushing’s syndrome is rare, but assessment of patients with clinical suspicion of Cushing’s and/or adrenal incidentaloma is frequently required. Thus, there is a need for biochemical screening methods that with high sensitivity and specificity identifies or rule out hypercortisolism. Analysis of late night salivary cortisol allows an easy sampling procedure performed at home and is independent of variations in plasma CBG levels. Analysis by liquid chrom...

Endocrine disrupting chemicals (EDCs) produce adverse effects associated with numerous pathologies: neurological disorders, metabolic diseases, infertility and cancer for example. How EDCs interfere with the development of hormone-sensitive tissue is a major question in biology. In this study, we propose that the model of prostate organoids can be used to study the effects of EDCs on the development of the prostate gland. Indeed, the differentiation of adult stem cells (ASC) i...
