Introduction: The humanized antibody anti-CD52+ alemtuzumab has been approved since 2014 for the treatment of relapsing-remitting multiple sclerosis (RRMS). Immune reconstitution after alemtuzumab induces thyroid autoimmunity in 34-41% of patients with RRMS, with Graves’ disease (GD) accounting for 63-65% of cases. Graves’ Orbitopathy (GO) may also occur in 13% of patients after alemtuzumab and is scarcely reported. Here we present the first case of alemtuzumab-induc...

TSH is involved in the immunomodulation of early pregnancy stages. Thyroid guidelines have indicated 2.5 mU/l as the best TSH level below which women undergoing assisted reproductive technology (ART) need to be maintained, though this treshold is still controversial. Aims of the present study were to evaluate if pre-conceptional TSH is associated with an increased risk of miscarriage, to identify a TSH cut-off significantly associated with risk of miscarriage and to assess the...

In the last decades, multi-tyrosine-kinase inhibitors (mTKI) have emerged as an effective treatment for radioiodine refractory differentiated thyroid cancer. Due to their pleiotropic mechanism of action, these drugs may cause different side effects. Hypocalcaemia has been reported in up to 35% of patients treated with mTKI, but up to date little is known about its pathophysiology and relevance. We report the case of a 78 years old woman operated on for a papillary thyroid canc...

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease ranging from intrahepatic lipid accumulation to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Liver 5β-reductase (AKR1D1) catalyses a fundamental step in bile acid (BA) synthesis. BAs and BA intermediates are potent regulators of metabolic and proliferative phenotype. We have hypothesised that AKR1D1 plays a crucial role in NAFLD and HCC. Liver biopsies and serum samples were obtained from healt...

Background: The dexamethasone suppression test (DST) is among essential tests for hypercortisolism diagnosis. Due to high sensitivity and specificity, liquid chromatography-tandem mass spectrometry (LC-MS/MS) is replacing obsolete immunoassays (IA) for steroid measurement. However, exhaustive data about IA and LC-MS/MS concordance in the frame of DST are still not available.Aim: To compare cortisol measurements by two routine IAs and LC-MS/MS in basal (F...

Introduction: Hyponatremia is the most common electrolyte disorder encountered in clinical practice and is associated with increased mortality and morbidity, including an increased risk for osteoporosis and fragility fractures. Preclinical studies suggest osteoclast upregulation whereas a clinical study showed improved osteoblast fuction after hyponatremia normalization in hospitalized patients with SIAD.Methods: This is a secondary analysis of a double-...

Introduction: Osteoporosis is a multifactorial disease characterized by reduced bone mass and increased risk of fragility fractures. Menopause predisposes women to osteoporosis due to declining estrogen levels. Iron is known to play a relevant role in the development of osteoporosis since iron suppresses osteoblast formation and may also stimulate osteoclast resorption of bone. Also, homocysteine is a known risk factor for osteoporotic fractures and is related to DNA methylati...

Introduction: Osteoporosis is a frequent complication associated with primary hyperparathyroidism (PHPT), and surgery is the most effective treatment once established. However, many patients are not candidates for it, and different medical options have been investigated. We aimed to assess the efficacy of denosumab (DMAB) in increasing bone mineral density (BMD) and preventing PHPT-related complications.Methods: Case-control study defining cases (Group 1...

Introduction: Diabetes mellitus (DM) develops early in Turner syndrome (TS) and appears not related to common risk factors. The precise mechanism of its development is still a matter of debate: a defective insulin response seems to be involved, but the role of incretins is still undefined.Objective: To evaluate the implication of incretin release in the early stages of DM development in TS. Materials and Methods: 153 Turner patient...

Introduction: There have been more than 130 genes described in relation with the development of obesity, which condition hyperphagia and early obesity. The aim of this study is to determine the prevalence of genetic alterations in a cohort of patients with morbid obesity.Materials and Methods: We designed a descriptive cross-sectional study for a cohort of subjects with obesity grade III or higher (BMI ≥40 kg/m2), treated at endocrinolog...
