Cinacalcet reduces serum calcium in intractable primary hyperparathyroidism (PHPT)

Marcocci Claudio , Fernandez-Cruz Laureano , Sunfa Cheng , Ren Lulu , Peacock Munro

Patients with persistent PHPT after parathyroidectomy (PTX) or contraindications for PTX often require chronic treatment for hypercalcemia, representing an unmet medical need. In an open-label, single-arm study in the US and EU, 17 patients underwent a variable length titration phase (maximum 16 weeks) with a maintenance phase (MP) of up to 3 years. Patients were eligible if they had (1) persistent PHPT following PTX or were considered contraindicated for PTX, and (2) serum ca...

Evaluation of acromegaly status following surgery by OGTT, GH day curve and IGF-I: relationships between these parameters

Karavitaki Niki , Fernandez Alberto , Fazal-Sanderson Violet , Turner Helen E , Wass John AH

Background: Nadir GH<2 mU/l in OGTT, normal IGF-I and mean GH<5 mU/l in the growth hormone day curve (GHDC) are considered the therapeutic endpoints in patients with acromegaly. However, discrepancies between these parameters have been reported.Aim: To compare the utility of the above tests in assessing the acromegaly status following surgical treatment.Patients and methods: Twenty-six consecutive patients (16 females) diag...

Differences in the presenting biochemical and imaging data in patients with acromegaly caused by pure GH adenomas, adenomas with GH and PRL cell differentiation and plurihormonal adenomas

Fernandez A , Karavitaki N , Ansorge O , Fazal-Sanderson V , Turner HE , Wass JAH

Introduction: Pituitary adenomas causing acromegaly are immunocytochemically divided into 3 main groups: growth hormone (GH) cell (A), those with GH and prolactin (PRL) cell differentiation (B) and plurihormonal (C). Recent large series comparing the hormonal and imaging features of these tumours at diagnosis are lacking.Objectives: To investigate differences in the presenting hormonal and imaging data associated with the above groups of adenomas.<p ...

Risk estimator for autonomous cortisol secretion in adrenal incidentalomas. Retrospective study of 100 cases

Castro Marta Araujo , Nunez Miguel Sampedro , Gonzalez Elena Fernandez , Moreno Nerea Aguire , Azpiroz Monica Marazuela

Purpose: A combined model of clinical, biochemical and radiological variables could help to predict autonomous cortisol secretion (ACS) in adrenal incidentalomas (AI).Methods: We analyzed retrospectively 100 patients diagnosed of AI between 2011 and 2015. AI was defined as an adrenal mass>1 cm, accidentally discovered by radiologic examination. ACS was ruled out (ACS-) by serum cortisol post-dexamethasone suppression test (Nugent) <3 μg/dl, ...

Oral glucose tolerance test vs fasting plasma glucose determination for the assessment of glucose metabolism disturbances in women with Polycystic Ovary Syndrome

Ortiz Andres , Fernandez Elena , Alvarez Francisco , Santacruz Elisa , Rosillo Marta , Escobar Hector , Luque Manuel

Background: Polycystic ovary syndrome (PCOS) is a common endocrine condition in women at reproductive age, in whom, glucose metabolism disturbances are commonly observed. In addition, overweight and obesity, especially visceral obesity, are more prevalent in PCOS women, which enhances the resistance to insulin action, and as consequence, the onset of impaired glucose tolerance (IGT) and/or type 2 diabetes mellitus (T2DM). Clinical guidelines recommend oral glucose tolerance te...

131I-MIBG as a treatment in medullary thyroid carcinoma with distant metastases.

Uriarte Nerea Utrilla , Fernandez Pedro Gonzalez , Figueruelo Alba Esteban , Herrero Marina Nevares , Sandi Javier Santamaria

Introduction and objectives: The strategies for therapy of metastatic medullary thyroid carcinoma (MTC) are limited. Although Tyrosine kinase inhibitors (TKI) seem to be the first-line treatment, we want to explore other possibilities. Metaiodobenzylguanidine (MIBG) is a guanethidine derivative, structurally similar to norepinephrine. It was developed as an imaging agent with 123I radiolabeling. MIBG localizes neuroendocrine tumors including MTC. We are investigatin...

Tyrosine kinase inhibitors in iodine-refractory thyroid cancer. Clinical experience

Marijuan Clara , Pla Begona , Aguirre Nerea , Fernandez Elena , Hernando Inigo , Jimenez Sara , Marazuela Monica , Lahera Marcos

Introduction: Tyrosine kinase inhibitors (TKIs) are used for treatment of iodine-refractory differentiated thyroid cancer (DTC) in patients with progressive advanced disease.Sorafenib and lenvatinib are the TKIs currently approved for this indication.Objective: To describe the clinical experience in patients with iodine-refractory DTC treated with TKIs in our Institution.Materials and methods: Restrospective cohort study of patient...

Gender differences in patients with coronary heart disease and diabetes. A retrospective study

Fernandez-Ladreda Mariana Tome , Jimenez Ana Isabel , Garcia-Doncel Lourdes Garcia

Introduction: There are known biological differences between men and women in coronary heart disease. It is important to know these differences in order to avoid inequalities in prevention, diagnosis and treatment of this pathology.Methods: We designed a retrospective, descriptive study in which we included all diabetic patients admitted to the hospital with acute coronary syndrome in 2016. Demographic data and degree of control of risk factors were regi...

Development of an image-based method for spatial registration of T3-induced changes in cell types and gene expression in human cerebral organoids

Bresser Audrey , Obermayer-Wasserscheid Benedikt , Megges Matthias , Fernandez-Vallone Valeria , Stachelscheid Harald , Kuhnen Peter , Opitz Robert

Thyroid hormone (TH) signaling is essential for nervous system development. The clinical relevance of this simple statement is underscored by the severe neurological phenotypes resulting from global TH deficiency or perturbed local TH signaling during fetal development. A major aim of our research is to better understand the local action of TH during early human cortex development using cerebral organoids derived from human induced pluripotent stem cells (hiPSC) as a model sys...

Premature Adrenarche and metabolic dysfunction – a systematic review and meta-analysis

Said Wogud Ben , Lempesis Ioannis , Garcia Silvia Fernandez , Thangaratinam Shakila , Arlt Wiebke , Idkowiak Jan

Background: Androgen excess frequently manifests in pre-pubertal children as premature adrenarche (PA). PA is characterised by the development of pubic and axillary hair, adult-type body odour in girls <8yrs and in boys <9yrs. PA may be a forerunner condition of polycystic ovary syndrome (PCOS), a complex metabolic disorder characterised by androgen excess. It is well established that women with PCOS have high risk of insulin resistance and frequently develop type 2 di...
