Context: Ipilimumab is a human monoclonal antibody against cytotoxic T lymphocyte antigen-4 (CTLA-4), which enhances stimulation of cytotoxic T lymphocytes, resulting in an immune response against the tumour. This drug-induced hyperactivity of the immune system can lead to serious adverse effects including endocrine disorders such as autoimmune hypophysitis, thyroiditis and adrenal insufficiency.Objective: To report our experience on ipilimumab-induced h...

Introduction: Heterozygous inactivating mutations of the calcium sensing receptor (CaSR) gene cause mild alterations in calcium metabolism (familiar hypocalciuric hypercalcemia (FHH)). However, in addition to the parathyroid gland CaSR expression was recently identified in the myocardium and many other endocrine cells including pancreatic islet cells, entero-endocine cells and adipose tissue. So far, it is unknown whether FHH is associated with cardio-metabolic altera...

Background: Aldosterone levels are elevated in normal pregnancy but fall despite volume contraction in preeclampsia. Vascular endothelial growth factor (VEGF) and soluble fms-like tyrosine kinase 1 (sFlt-1) have been implicated in this phenomenon in vitro and in animal work. Low placental growth factor (PlGF), which is closely linked to VEGF signalling, identifies women at risk of preeclampsia between 20 and 35 weeks gestation. We aimed to examine these relationships ...

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....
