Late Diagnosis of Childhood Adrenal Insufficiency and Hypogonadotropic Hypogonadism due to DAX 1 Gene Mutation

Karantza Maria , Bogris Sotirios , Chrousos George , Sertedaki Amalia

Background: DAX-1 mutation is a rare genetic cause of adrenal insufficiency also causing hypogonadotropic hypogonadism.Case presentation: The patient was born to a G1P1 mother. At the age of 1 month he developed acidosis, hyponatremia, hyperkalemia, diagnosed with congenital adrenal hyperplasia and started on hydrocortisone and fludrocortisone. No CYP 21 mutation was identified, fludrocortisone was continued for presumed hypoaldosteronism, hydrocortisone...

β-Cells’ Functional Exhaustion at Type 1 Diabetes Onset may Lead to Early Microvascular Complications

Papadopoulou Nektaria , Dacou-Voutetakis Catherine , Chrousos George , Kanaka-Gantenbein Christina

Background: Diabetic ketoacidosis (DKA) is a severe and often the inaugural clinical manifestation of type 1 Diabetes (T1D). Diabetic nephropathy is one of the most devastating chronic complications of T1D and its’ early diagnosis is traditionally based on microalbuminuria.Objective and hypotheses: The aim was to investigate the possible associations between the initial clinical manifestations and the chronic complications of T1D.<p class="abste...

Experience of 6-months of burosumab therapy in five siblings with X-linked hypophosphataemic rickets in the State of Kuwait

Shammari Sameer Al , Enezi Ayed Al , Sameer George , Fawzy Nagla ,

Background: X-linked hypophosphataemic rickets (XLH) is a genetic disorder, characterized by hypophosphatemia and caused by a mutation in the phosphate regulating endopeptidase homolog, X-linked (PHEX) gene which leads to overexpression of fibroblast growth factor 23 (FGF23).1,2 Conventional therapy, supplementation with oral phosphate and vitamin D analogs, does not treat the underlying cause of the disorder and is associated with poor treatment ad...

Vosoritide Clinical Study Data Demonstrates CXM is a Superior Biomarker of Endochondral Bone Growth

Larimore Kevin , Nguyen Thom , Qi Yulan , Jeha George , Zoog Stephen ,

Vosoritide is a C-type Natriuretic Peptide (CNP) analogue therapy for treatment of achondroplasia. Vosoritide acts on growth plate chondrocytes through the Natriuretic Peptide Receptor-B to stimulate increased endochondral bone growth, leading to increased growth velocity in treated subjects. In Phase II clinical studies, subject blood and urine samples were analyzed to monitor putative bone growth biomarkers including cross-linked C-terminal telopeptides of collagen II (CTxII...

Thermoregulatory delays in Greek PCOS adolescents

Geronikolou Styliani , Chrousos George , Cokkinos Dennia , Bacopoulou Flora ,

In this case-control study 19 Greek adolescents with Polycystic Ovary Syndrome (PCOS) and 21 non-PCOS controls were assessed for their hormonal, somatometric and autonomic nervous system profile in supine position. The study adhered to the Helsinki Guidelines of Good Clinical Practice. Significant differences were found only in very low frequencies (VLF) (P = 0.008) and Power spectral density RR (PSD) (P < 0.001) between adolescents with PCOS and controls...

Background: Implementation of neonatal screening programs for congenital hypothyroidism (CH) has reduced related nosologies and has eradicated CH-associated mental impairment. With the decrease of the TSH cut-off limits employed to avoid false negative results, milder cases of CH are diagnosed. Obviously, in a number of patients, especially among milder CH cases, thyroid dysfunction is transient. The diagnosis of transient vs. permanent CH is established in time. No specific p...

Abstract: Objective: Congenital hypogonadotropic hypogonadism (CHH) is a rare genetic disease caused by GnRH deficiency and characterized by absent or incomplete puberty with infertility. The identification of the genetic cause in this group of patients through the use of next generation sequencing (NGS) can assist to the clinical management.Methods: Seven GnRH deficient nonrelated Cypriot probands were ...

Search for Genetic Defects in the Transcription Factor Genes FOXL2, FOXE1, BMP15, NOBOX, and GDF9 in Children, Adolescents and Young Adults With Premature Ovarian Insufficiency POI

Background: Molecular defects are rarely detected in Premature ovarian insufficiency (POI) patients.Objective and Hypotheses: We hypothesized that the frequency of causative molecular defects could be higher in cases with early onset of POI. Moreover, the analysis of multiple genes in the same POI group could disclose co-existence of more than one molecular aberration.Method: In 25 subjects, aged 17.1±7 years at POI onset, bid...

Background: Transient generalized glucocorticoid hypersensitivity is a rare disorder characterized by increased tissue sensitivity to glucocorticoids and compensatory hypoactivation of the hypothalamic–pituitary–adrenal (HPA) axis. The condition itself and the molecular mechanisms that underlie its pathophysiology have not been elucidated as yet. Adenovirus 36 has been reported to cause obesity in various animal species.Objective and Hypotheses...

Characteristics and Outcome of Neonates with Congenital Hypothyroidism Born After In Vitro Fertilisation

Background: In vitro fertilisation (IVF) has been widely used during the last decades. Increased susceptibility to birth defects and a higher cardiometabolic risk in children born after IVF than naturally conceived (NC) children have been reported. Also, a higher incidence of hyperthyrotropinemia has been noted in children born after IVF with respect to NC children and has been attributed to an epigenetic modification of the TSH set-point.Object...
