Introduction: Cyclic Cushing’s syndrome (CS) is a rare disorder, characterised by alternating periods of normo – and hypercortisolism.Case report: An 18-year-old young man was followed at the Department of Growth and Reproduction due to Klinefelter and received androgen replacement since the age of 12. As he was shifted to i.m. injections his liver enzymes increased and liver damage due to androgen replacement was suspected. A liver biopsy show...

Introduction: Acromegaly is a rare disease caused by GH hypersecretion from a pituitary adenoma. However, accurate estimates of incidence and prevalence are scarce and not based on nationwide populations. It is well known that surgical cure may normalize mortality and improve morbidity but similar data are not available for patients receiving medical treatment.Method: We first validated the ICD-8 and ICD-10 diagnosis codes for acromegaly in The National ...

Background: Vitamin D is important to skeletal health and is standard care in conditions with low BMD. Thyrotoxicosis caused by Graves’ disease (GD) leads to increased bone turnover and reduced BMD. We aimed to test the hypothesis that vitamin D supplementation would improve bone recovery in GD.Methods: Using a double-blinded design, hyperthyroid patients with a first time diagnosis of GD were randomized to supplementation with vitamin D3 70 mg/day...

Introduction: Maternal obesity is associated with increased risk of metabolic dysfunction in the offspring. It is not clear which physiological aspects of the obese state that cause this metabolic programming. Obesity causes many metabolic changes but also low grade inflammation. In this study, we have determined if increased low grade inflammation was present in obese dams compared to controls dams during gestation.Methods: Female C57BL/6 mice were fed ...

Introduction: Recently, it has been suggested that hypopituitarism developed after the brain injury has implications in the final recovery of the patients. We hypothesize that hypopituitarism developed in the course of traumatic brain injury (TBI) or non-TBI is related to worse functional outcome. The aim was to assess the association between hypopituitarism in the early recovery phase and long-term functional outcome.Materials and methods: We included 1...

Pre-autonomic neurons in the hypothalamic paraventricular nucleus (PVN) project to sympathetic and parasympathetic motor nuclei in the brain stem, from where the liver and white adipose tissue (WAT) are innervated by both branches of the autonomic nervous system (ANS). Studies by our group and by others have shown that these neural pathways modulate glucose and lipid metabolism in liver and WAT. Given the abundant thyroid hormone receptor (TR) expression in the PVN we hypothes...

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: Several numerical chromosome abberations are known in men. Of those the karyotype XXY (Klinefelter syndrome KS) is the most common chromosomal disorder with a prevalence of about one in 500 live-born males. KS is associated with hypogonadism and is suspected to cause variable physical and cognitive abnormalities. As a supernumerary X chromosome is also associated with infertility, sound animal models for KS are difficult to obtain.Methods: ...

Introduction: Thyroxine-binding globulin (TBG) is the main thyroid hormone transport protein in blood. So far, 26 TBG deficiency mutations have been reported, 7 of them leading to partial TBG deficiency. We examined T4 binding capacity and the TBG gene in patients with normal free T4 (fT4) and reduced total T4 (TT4). We present and characterize five new partial TBG deficiency mutations.Methods: Automated chemiluminescence immunoassays were used for the d...

Objective: To estimate the occurrence of hypopituitarism 12 months following traumatic brain injury (TBI), describe the time course, evaluate the predictive value of early hormonal changes and trauma related parameters, as well as out-come.Methods Forty-six patients with TBI (mild (GCS:13–15) n=22; moderate (GCS:9–13) n=9; severe (GCS<9) n=15) were included. Patients were tested early post-injury (baseline hormone level...
