Birth Characteristics Influence the Male to Female Diagnostic Prevalence of Idiopathic GH Deficiency

Camacho-Hubner Cecilia , Lindberg Anders , Arnhold Ivo J P , Ranke Michael B

Background: A greater number of male (M) vs female (F) patients are diagnosed with GH deficiency (GHD). M have larger birth weight (BW), length and head circumference (HC) compared to F; these characteristics could contribute to subtle cephalo-pelvic disproportion and mild head trauma possibly contributing to idiopathic GHD (IGHD) and multiple pituitary hormone deficiencies (MPHD).Objective: To determine birth characteristics including mode of delivery a...

The association between serum Thyrotropin within the reference range and cardiometabolic risk in obese children

Tropeano Angelo , Corica Domenico , Curatola Selenia L. , Pomi Alessandra Li , Casto Celeste , Pepe Giorgia , Aversa Tommaso , Alibrandi Angela , Wasniewska Malgorzata ,

Background: The adaptative increase of serum thyrotropin (TSH) levels in obese subjects may affect the metabolic regulation of body tissues and thus promote an unfavorable cardiometabolic profile.Aim: To investigate the association between serum TSH, free thyroxine (FT4) and cardiometabolic risk factors in euthyroid obese children and adolescents.Material and Methods: Four hundred ninety-one Caucas...

Biotine Interference in a Patient with Non-Clinic High Thyroid Hormone Levels

Ayranci Ilkay , Filibeli Berna Eroglu , Manyas Hayrullah , Dündar Bumin Nuri , Çatli Gönül

Introduction: Differential diagnosis of thyroid hormone resistance (beta) and TSHoma should be made in patients with high free thyroxine (f-T4) and free triiodothyronine (f-T3) and non-suppressed thyroid stimulating hormone (TSH) levels. The aim of this study was to present the results of etiological research in a patient with Down syndrome who was clinically euthyroid and had high levels of f-T4, f-T3, normal TSH levels.Case</st...

Pluripotent Stem Cells in Endocrinology

Leibel Rudolph L.

The ability to differentiate human embryonal stem cells (hESC) and induced pluripotent stem cells (hiPSC) into virtually any cell type has enabled the creation of cellular models of diseases for which human cells are not readily accessible. Using these strategies, we have examined the molecular pathogenesis of monogenic forms of diabetes such as Wolfram’s syndrome and various MODYs using stem cell-derived insulin producing cells created from fibroblasts of patients with t...

Hypothalamic Obesity in Craniopharyngioma

Muller Hermann L. ,

Although craniopharyngiomas are of low-grade histological dignity and have good prognosis in terms of overall survival, survivors may suffer from devastating consequences caused by hypothalamic damage. Disease and/or treatment-related hypothalamic damage leads to disturbed hunger-satiety and thirst feelings, decreased energy expenditure, behavioral problems, disturbances of circadian rhythm, temperature dysregulation, and pituitary dysfunction. These patients are at great risk...

Novel LZTR1 mutations in subjects with features of Noonan Syndrome and GH insensitivity negatively regulate GH-induced IGF-I production and hyperactivate GH-induced ERK1/2 activation in response to GH in vitro

Chatterjee Sumana , Romeo Bertola Debora , Agwu Chizo , Maharaj Avinaash , Williams Jack , Cottrell Emily , Shapiro Lucy , Andrews Afiya , Savage Martin O. , Gaston-Massuet Carles , Metherell Louise A. , Storr Helen L. ,

Background: Noonan Syndrome (NS) can overlap clinically and biochemically with growth hormone insensitivity [GHI; short stature (SS), low IGF-I and normal/elevated GH levels]. Mutations in multiple genes regulating RAS/MAPK pathway have been identified in NS including LZTR1 variants. Function of LZTR1 is poorly understood and its role in growth retardation is unknown.Objectives: To functionally characte...

Serum AMH Levels are Lower in Healthy Boys Who Develop Pubertal Gynaecomastia

Mieritz Mikkel G , Hagen Casper P , Almstrup Kristian , Petersen Jorgen H , Raket Lars L , Sommer Stefan H , Juul Anders

Background: Pubertal gynaecomastia is thought to be a clinical sign of an oestrogen-androgen imbalance, affecting up to 60% of boys. In most cases no underlying endocrinopathy can be identified. In boys, Anti-müllerian hormone (AMH) is produced by immature Sertoli cells and circulating level decreases as testosterone increases during pubertal maturation. In a previous cross sectional study we found significant lower levels of AMH in boys with pubertal gynaecomastia (Mieri...

Prolactinomas in Children and Young Adults: 10 Year Experience in a Tertiary Regional Paediatric - Young Adult - NeuroEndocrine Surgical Centre

Kalitsi J , Kapoor RR , Kalogirou N , Thomas NP , Aylwin SJB , Buchanan CR

Background: Prolactinomas are rare in the prepubertal and adolescent age group. Therapeutic approaches are guided by experience from treating adults. Few series have been reported.Objective: Retrospective analysis of presenting features, treatment and outcomes in young patients presenting to a Tertiary Endocrine Service (total referral population ~3.5 million) managed jointly between Paediatric and Adult Endocrine and Neurosurgical services.<p class=...

Efficacy of Supplemental Liothyronine for Patients with Congenital Hypothyroidism and Pituitary Resistance to Thyroid Hormone

Paone Laura , Fleisch Abby F , Feldman Henry , Cappa Marco , Brown Rosalind , Wassner Ari J

Background: Recent guidelines recommend levothyroxine (LT4) monotherapy for all infants with congenital hypothyroidism (CH). However, up to one-third of patients have pituitary resistance to thyroid hormone and, to normalize their TSH, require supranormal circulating levels of T4. Liothyronine (T3) has been proposed as a supplemental therapy for such patients, but data demonstrating its use and efficacy are limited.Object...

Two Patients with Allen–Herndon–Dudley Syndrome: a Novel Mutation on MCT8 Gene

Mutlu Gul Yesiltepe , Kirmizibekmez Heves , de Souza Elaine C Lima , Hatun Sukru , Visser Theo J

Background: Monocarboxylate transporter 8 (MCT8) is a specific transporter of triiodothyronine (T3). MCT8 gene mutations cause a rare X-linked disorder known as Allan–Herndon–Dudley syndrome, characterized by thyroid dysfunction (high T3, low T4, and normal/high TSH) and psychomotor retardation.Case report: A 4-year- and 9-month-old boy, who was already having L-T4 treatment fo...
