Background and aim: The dual-release hydrocortisone Plenadren® has shown promising results of improved cardiovascular and metabolic profiles after treatment of adrenal insufficiency, possibly due to an improved circadian profile of cortisol, but results are ambiguous. Aim: To further investigate the potential effect of dual-release hydrocortisone on the metabolic profile as compared to conventional hydrocortisone in patients with secondary adrenal i...

Background: Craniopharyngioma may be associated with severe morbidity. Few data exist on incidence rate (IR) and possible changes with time. The epidemiology of craniopharyngioma in Denmark has never been evaluated in detail.Objectives: To review the literature on craniopharyngioma incidence and to study the epidemiology of craniopharyngioma in Denmark during a recent 20-year period.Material and methods: Publications including data...

Objective: To determine the cumulative incidence of nonadherent patients with type-2-diabetes from an outpatient clinic, and to examine determinants and consequences of premature discharge.Research design and methods: A cohort comprising patients with type-2-diabetes referred to a Diabetes Clinic from 2009-2012 was assessed. Patients were categorized as nonadherent if discharged within two years of referral due to nonattendance and/or nonadherence to med...

Background and aims: Non-prescribed use of anabolic-androgenic steroids (AAS) is associated with a wide range of health risks including AAS-induced hypogonadism (ASIH) caused by negative feedback suppression on the hypothalamic-pituitary-gonadal (HPG) axis. Testicular function might be reduced for months up to years after AAS-cessation, increasing the risk of developing fatigue, decreased libido, erectile dysfunction, infertility, sleep disorder, depression and anxiety. There ...

Background: The differential diagnosis of the polyuria-polydipsia syndrome is challenging. The water-deprivation test is the current gold standard, but the test is cumbersome, and the diagnostic performance is poor. Copeptin, which is a split product of the vasopressin pre-propeptide, appears to be a robust biomarker in the circulation and a promising tool for the diagnosis of patients with polyuria and polydipsia, especially when measured in conjunction with intravenous infus...

Background: Growth hormone (GH) potently stimulates lipolysis, and after GH exposure, levels of serum free fatty acids (FFAs) increase in a distinct temporal pattern characterized by a 1-hour lag phase and a peak after 3 hours followed by a gradual return to baseline. This effect predominantly operates during fasting and promotes utilization of lipids from adipose tissue (AT) at the expense of glucose and protein. Prolonged fasting also downregulates the expression of the G0/G...

Introduction: Patients planned for first time surgery for clinically non-functioning pituitary adenoma (NFPA) were included in this prospective study.Aims: – To study the prevalence of hypothalamic-pituitary-adrenal (HPA) axis failure preoperatively and 3 months after surgery for clinically NFPA.– To investigate factors predicting risk of HPA axis failure postoperatively.Hypotheses<p class="abst...

Background: Long-term safety data (1998 to mid-2016) are reported for adult patients with GHD treated with GH (Norditropin® (somatropin), Novo Nordisk) as prescribed by treating physicians in the real-life clinical setting and enrolled in NordiNet® International Outcome Study (IOS) (NCT00960128), a non-interventional, multicentre study.Objective and hypotheses: To describe and report safety data and incidence rates (IRs) (...

Background: Patients with adrenal insufficiency (AI) exhibit increased morbidity, mortality and impaired quality of life (QoL) and conventional hydrocortisone replacement does not mimic the endogenous circadian pattern and may compromise adherence. A modified – release hydrocortisone formulation (Plenadren) for once-daily use is licensed in order to meet these needs.Objective: To audit the effects of treatment change from HC to Plenadren in an out-p...

Context: Obesity is accompanied by blunted GH secretion but relatively normal serum IGF-I levels, which suggests increased GH sensitivity. This, however, remains to be tested at the level of GH signaling in human subjects.Objective: To compare the effects of an acute intravenous GH bolus in obese vs normal weight subjects on GH signaling pathways in adipose and muscle tissue, substrate metabolism and insulin sensitivity.Subjects an...
