Hypopituitarism has been associated with an increased mortality, which may be due to untreated growth hormone (GH) deficiency but also to the various underlying disorders. We therefore analysed mortality in patients with only one underlying disorder, non-functioning pituitary adenoma (NFPA), with and without GH replacement therapy (GHRT). Patients with NFPA in the western region of Sweden, 1997-2011, were identified through the National Patient Registry and cross-referenced with several National Health Registries...

Rituximab (RTX) use in open label series has been associated with very encouraging responses in patients with active and moderate-to-severe Graves' Orbitopathy (GO). Recently randomized controlled trials of RTX have been performed in such patients in order to answer the question of clinical efficacy and the safety profile of this agent. That data, reported separately, focused on Clinical Activity Score (CAS) and indicated in one trial a strong benefit of RTX in comparison with IV glucocorticoids while the other trial noted the absence of a benefit by comparison with placebo...

Background Hypomagnesemia (plasma magnesium (Mg2+) concentration <0.7 mmol/L) has been described in patients with type 2 diabetes. Polypharmacy is inevitable when treating a complex disease such as type 2 diabetes and could explain disturbances in the plasma Mg2+ concentration. In this study, we aimed to establish the extent of hypomagnesemia in a cohort of type 2 diabetes patients and to identify determinants of plasma Mg2+ levels. Methods Patient data and samples of 395 type 2 diabetes patients were investigated...

Nutrition can generate oxidative stress and trigger a cascade of molecular events that can disrupt oxidative and hormonal balance. Nutrient ingestion promotes a major inflammatory and oxidative response at the cellular level in the postprandial state, altering the metabolic state of tissues. A domino of unfavorable metabolic changes is orchestrated in the main metabolic organs, including adipose tissue, skeletal muscle, liver and pancreas, where subclinical inflammation, endothelial dysfunction, mitochondrial deregulation and impaired insulin response and secretion take place...

OBJECTIVE: Autonomously functioning thyroid areas may be associated with subclinical or overt hyperthyroidism, but may exist even in the presence of normal TSH. This study was aimed at comparing the rate of autonomously functioning areas and their cardiac sequelae in patients with nodular goitre studied with the usual and a novel approach. DESIGN AND METHODS: A total of 490 adult outpatients with thyroid nodular goitre, living in a mild iodine-deficient area, were selected in our Referral Center for thyroid diseases from 2009 to 2014 on the basis of a suspicion of thyroid functional autonomy...

INTRODUCTION: Patients with SDHx mutations need long-term radiological surveillance for the development of paragangliomas and phaeochromocytomas, but no longitudinal data exist. We assessed the performance of rapid-sequence non-contrast magnetic resonance imaging (MRI) in the long-term monitoring of patients with SDHx mutations. METHODS: Retrospective study between 2005-2015 at a University Hospital and regional endocrine genetics referral center. Clinical and imaging data of forty-seven patients with SDHx mutations [SDHB (36), SDHC (6), SDHD (5)] who had surveillance for detection of paragangliomas by rapid-sequence non-contrast MRI (base of skull to pubic symphysis) were collected...

OBJECTIVE: An excess of glucocorticoids (Cushing's syndrome) is associated with metabolic syndrome (MetS) features. Several single nucleotide polymorphisms (SNPs) in the glucocorticoid receptor (GR) gene influence sensitivity to glucocorticoids, and have been associated with aspects of MetS. However, results are inconsistent, perhaps due to the heterogeneity of the studied populations and limited samples. Furthermore, the possible association between functional GR SNPs and prevalence of MetS remains unexplored...

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine condition in premenopausal women. The syndrome is characterized by hyperandrogenism, irregular menses and polycystic ovaries when other etiologies are excluded. Obesity, insulin resistance and low vitamin D levels are present in more than 50% patients with PCOS, these factors along with hyperandrogenism could have adverse effects on long term health. Hyperinflammation and impaired epithelial function were reported to a larger extent in women with PCOS and could particularly be associated with hyperandrogenism, obesity and insulin resistance...
