Background: Hormone replacement therapy (HRT) in post-menopausal women carries an increased risk of cardiovascular disease due to an unfavorable effect on lipid profile. Thus, HRT treatment increases concentrations of very-low-density-lipoprotein-triglycerides (VLDL-TGs) which have been demonstrated to possess atherogenic properties. However, the exact mechanisms whereby VLDL-TG concentrations are increased by estradiol are not fully understood. Estradiol acts on both rapid re...

Introduction: Amino-Bisphosphonates (N-BPs) are potent inhibitors of the bone resorption, they inhibit enzymes of the intracellular mevalonate pathway required for prenylation of different important signaling proteins. In order to study the genetic basis of the variability in therapy response we have analysed the polymorphism of farnesyl pyrophosphate-synthase (FDPS) gene in 234 postmenopausal Danish women treated with N-BPs for 1 and 2 years.Methods: Th...

Introduction: Thyroid autoimmunity has been associated with pregnancy loss. A possible mechanism is an overactive maternal immune system leading to rejection of the fetal allograft. In women with recurrent pregnancy losses (RPL), we investigated the association of thyroid peroxidase antibodies (TPOAbs) with number of losses and outcome of first pregnancy after referral.Methods: Prospective study of women with RPL (≥3) followed at the RPL Unit, Cope...

Background: Hypercortisolism is prevalent in type 2 diabetes (T2D), but analytical and functional uncertainties prevail. Measurement of salivary cortisol is considered an expedient screening method for hypercortisolism, but its usefulness in the context of T2D is uncertain.Aim: To compare late night salivary cortisol (LNSC) with the 1 mg overnight dexamethasone suppression test (DST), which was considered ‘reference standard’, in T2D.<p cla...

Introduction: The presence of brown adipose tissue (BAT) in humans has recently been demonstrated by histology and positron emission tomography (PET). In previous reports, BAT in adults is primarily confined to the upper chest and neck. Here, we report a case of massive BAT infiltration of the visceral adipose tissue in a patient with catecholamine secreting paraganglioma.Methods: The patient was evaluated with [18F]-FDG PET/CT at three occasi...

Introduction: We questioned the justification of general recommendations for assessment of hypopituitarism in patients with traumatic brain injury (TBI), and aimed to describe the prevalence of hypopituitarism in a national TBI population of patients admitted to a Danish hospital in 2008, as compared to healthy controls.Patients and methods: We included 463 patients (18–65 years) hospitalized ≥24 h, with more than subtle TBI as indicated by lo...

Background: Diabetes mellitus is prevalent in adults with Prader–Willi syndrome (PWS), and GH therapy may deteriorate glucose balance.Design: We prospectively investigated effects of 12 months of GH treatment on body composition and insulin resistance in relation to BMI in forty-two adults, mean(±S.D.) age 28.5±6.7 years with genetically verified PWS. Three patients with known diabetes were excluded. Data from baseline and 1...

Background: Serum IGFI measurements are used during GH replacement in GHDA for titration of the GH dose, to monitor compliance and to avoid overdosing, but it is uncertain if pretreatment IGFI is a determinant of the GH dose or the response to GH treatment.Methods: Data from the NordiNet IOS have been analyzed to determine pretreatment serum IGFI concentrations in GHDA and to analyze if they influence the GH starting dose and/or the therapeutic response ...

Background: Data from several clinical studies have demonstrated the benefit of GH treatment in relation to bone mineral density and body composition in young adults who received GH treatment in childhood due to GHD1–3. There are recommendations to use a higher GH dose in the transition phase compared to the GH dose required during adulthood to mimic the endogenous GH secretion4,5.Methods: Data from NordiNet IOS have been analy...

Introduction: Prader–Willi syndrome (PWS) presents clinically with a multitude of findings, including abnormal body composition and partial GH deficiency. Until now three studies have reported beneficial effects upon body composition of GH treatment in adults with PWS. However, only one of these studies had the optimal randomised controlled design.Aim: The aim of this study was to confirm and substantiate the results from previous studies.<p cla...
