Background: Primary hyperparathyroidism (pHPT) is a common disease in a routine endocrinology praxis, but the biggest challenge is a localization of the adenoma and the further correct management of the disease. First FCPCT was reported in 2014 as the additional method of diagnosis of pHPT and in some centers has been already used as a first line diagnostic modality. However, FCPCT is still lacking in the European or International guidelines for the diagnosis of pHPT.<p cl...

Objective: Polycystic ovary syndrome (PCOS) affects 5–20% of women of reproductive age worldwide and is associated with disorders of glucose metabolism. Hormone and metabolic signalling may be influenced by phytoestrogens, such as isoflavones. Their endocrine effects may modify symptom penetrance in PCOS.We investigated, whether women with PCOS and healthy controls differ in their capacity to metabolize dietary isoflavones and whether this capacity...

Objectives: Sirolimus inhibits adipocyte differentiation (Yeh PNAS 1995). This study compares weight and fat markers in two groups of patients treated or not with sirolimus, before and after transplantation.Patients and method: Nineteen islet-alone transplanted patients treated with sirolimus and 7 islet-alone or liver-transplanted patients NOT treated with sirolimus were compared 1 year after transplantation in terms of weight, fat mass (equation of bod...

Objective: QT interval prolongation of unknown aetiology is common in Turner syndrome (TS). This study set out to explore the presence of known pathogenic long QT (LQT) mutations in TS and to examine the corrected QT interval (QTc) over time and relate the findings to the TS phenotype.Methods: Adult females with TS (n=102) were examined thrice with a mean follow-up of 4.7±0.5 years, and 68 age-matched healthy controls were examined once. QT...

Hyperandrogenism in women, most typically in polycystic ovary syndrome, is associated with insulin resistance and altered morphology and function of adipose tissue but little is known about the direct effects of androgen on adipose. The aims of this study were to investigate (1) distribution and relative abundance of androgen receptor (AR) in mouse adipose tissue (2) effect of temperature on AR expression in brown and white adipose depots (BAT, WAT) and (3) effects of androgen...

Background: Thyroid disease is associated with BMI with hyperthyroidism causing weight loss and hypothyroidism leading to weight gain. However, the relation of body weight distribution to thyroid function in euthyroid individuals is unclear. This study assessed body composition in euthyroid women.Methods: Euthyroid women (n=1072) from the Osteoporosis and Ultrasound Study (OPUS), a population based cohort study recruited participants from 5 Europe...

Introduction: Proton pump inhibitors (PPIs) were until very recently perceived to be safe, effective and inexpensive. As a result they are widely prescribed empirically, beyond their core indications. However dose-dependent adverse reactions increasingly reported include diarrhoea, resistant hypomagnesaemia/hypocalcaemia and interstitial nephritis. Moreover, they are associated with increased rates of vertebral and wrist fractures, and increased C. difficile carriage rate....

Background: Rapid and accurate risk stratification in patients with community-acquired pneumonia (CAP) is an unmet clinical need. Cortisol to DHEA ratio was put forward as a prognostic marker in sepsis. We herein validated the prognostic value of DHEA and DHEAS and of cortisol/DHEA- and cortisol-DHEAS – ratios, respectively, in patients with CAP as the most common (disease resulting) sepsis-defining illness.Methods: We assessed clinical parameters a...

While bariatric surgery is the most effective treatment strategy to maintain long-term weight-loss and to improve survival, it has not been shown, that bariatric surgery is as effective in craniopharyngeoma patients with hypothalamic obesity. We retrospectively analyzed weight loss and metabolic parameters in 7 craniopharyngeoma patients and 14 controls who underwent gastric banding surgery in five centers in Germany and Austria. The last before and the first patient after the...

Due to limited treatment options the prognosis of patients with advanced hepatocellular cancer (HCC) has remained poor. We therefore examined the feasibility of radioiodine therapy of HCC after human sodium iodide symporter (hNIS) gene transfer, using the tumor-specific alpha-fetoprotein (AFP) promoter for transcriptional targeting. For this purpose NIS gene transfer was performed in vivo in human HCC cell (HepG2) xenografts, using replication-deficient adenoviral vecto...
