Obesity is a major health problem commonly associated with severe comorbidities, including insulin resistance and type 2 diabetes mellitus (T2DM). Emerging evidence suggests that production and secretion of certain micro RNAs (miRNAs) are dysregulated under adverse metabolic conditions and might exert a key role in the development and progression of different metabolic-related pathologies. However, the alteration of the plasma miRNA profile under obesity condition and its path...

The standard technique for the functional imaging of pheochromocytoma and paraganglioma (PPGL) is [123I]-metaiodobenzylguanidine single photon emission computed tomography (MIBG SPECT). However, metastases are more accurately detected by 2-[18F]-Fluoro-2-deoxy-D-glucose positron emission tomography (FDG PET). In a large prospective study of 216 patients evaluated at the NIH for benign or malignant PPGL, we investigated the sensitivity and specificity of FDG PET ...

Objectives: Autoimmune diseases are typically studied with a focus on the immune system, and less attention is paid to responses of target tissues exposed to the immune assault. We aimed to evaluate, based on available bulk RNA sequencing data, whether inflammation induces similar molecular signatures in the target tissues of five autoimmune diseases, namely type 1 diabetes (T1D), Hashimoto’s thyroiditis (HT), rheumatoid arthritis (RA), multiple sclerosis (MS) and systemi...

Introduction: Malignant pheochromocytomas and paragangliomas (PPGLs) are rare, and knowledge of the natural history is limited. Material Methods: Data of 7 (7.6%) (out of 109) patients with malignant PPGLs referred to a Tertiary Centre of Endocrinology from Bucharest, Romania, were retrospectively collected. Follow-up ranged from 2004 to 2022. Demographic data, genetic status, site and size of primary tumor, biochemical activity, metastasis time (synchro...

Introduction: Pheochromocytomas (PHEOs) and paragangliomas (PGLs) are rare neuroendocrine tumors arising from chromaffin cells within adrenal medulla and autonomic paragranglia respectively. Recent evidences show that nearly one-third patients harbour germline mutation, namely in von Hippel-Lindau (VHL), REarranged during Transfection (RET), neurofibromatosis type 1 (NF 1) and succinate dehydrogenase (SDH) complex genes. However, the tumor morphology arising in various syndrom...

Pituitary apoplexy is a rare syndrome due to hemorrhagic infarction of a pituitary adenoma. We analyze the circumstances of diagnosis, clinical features and evolution in a retrospective review of patients with pituitary apoplexy admitted between 2000 and 2010, diagnosed by pathological exam and/or suggestive imaging for pituitary haemorrhage.Results: From 31 patients with pituitary apoplexy (11 women, 20 men) with a mean age of 48 years at diagnosis (20&...

Introduction: Leptin seems to be a major link between obesity and thyroid dysfunction.Design: To analyze the relationship between thyrotropin (TSH) and leptin (LP) plasma concentrations and body mass index (BMI), in 785 subjects (448 women) of 41.27±9.72 years and BMI 28.91±9.8 (18.04–93.98 kg/m2), without diagnosed thyroid disease or pregnancy, concentrations of TSH, free thyroxine (FT4), LP, glycemia and insulinemia...

Introduction: The clinical significance of subclinical thyroid diseases is debated.Design: To assess the relationship between undiagnosed subclinical hypothyroidism (USH), health indicators (HI) and cardiovascular risk factors (CVRF), this cross-sectional study was conducted in 1100 adults representatives of non-institutionalized Catalan population (44.5% men; mean age: 44.8±15.2 years) in Catalonia (Spain); 40 USH (18 men) and 1060 euthyroid (474 m...

Introduction: To evaluate if improved thyroid status in patients with hypopituitarism would improve cardiovascular risk markers.Patients and methods: A total of 85 hypopituitary patients (45 women) with GH deficiency; 7 had isolated GH deficiency, 25, 16 and 22 patients had 1, 2 and 3 additional deficits respectively. Fifteen patients had panhypopituitarism. Biochemical and body composition assessment was performed at baseline (when patients were GH na&#...
