A Novel Mutation in the NR3C2 Gene Causing Pseudohypoaldosteronism Type 1

Sertedaki Amalia , Kanaka-Gantenbein Christina , Chrousos George P

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disease characterized by mineralocorticoid resistance with subsequent salt wasting, hyperkalemia, metabolic acidosis, and elevated plasma renin and aldosterone levels.Patients and methods: We report a male newborn that presented with failure to thrive and sustained hyponatremia during his early postnatal period. He was conceived after IVF (twin pregnancy) and prematurely born by cesare...

A Large Family with a Novel Mutation in the SCNN1A Gene Causing a Mild and Transient form of Autosomal Recessive Pseudohypoaldosteronism Type 1 (PHA1)

Efthymiadou Alexandra , Sertedaki Amalia , Chrousos George , Chrysis Dionisios

Background: PHA1 is a rare inherited disease characterized by resistance to aldosterone action and distinguished in two forms: the autosomal dominant renal form caused by mutations of the NR3C2 gene (MR) and the autosomal recessive systemic form caused by mutations of the subunit genes SCNN1A, SCNN1B, SCNN1G of the epithelial sodium channel (ENaC). The classic phenotype of the autosomal recessive form of PHA1 is usually severe, lifelong, and expressed with mu...

Phaeochromocytoma in Placental Mesenchymal Dysplasia: Who Should We Screen and for How Long?

White Mary , McGillivray George , White Sue , Zacharin Margaret

Background: Beckwith-Wiedemann syndrome (BWS) characterised by a group of clinical abnormalities (macrosomia, macroglossia, neonatal hypoglycaemia, omphalocoele and umbilical hernia) results from dysregulation of imprinted genes due to mosaic paternal uniparental isodisomy (patUPD) of 11p15.5. Its association with tumours of embryonic origin is well documented and screening guidelines largely aim to detect hepatoblastoma and Wilm’s tumours during the first decade of life....

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...

The effect of a personalized, lifestyle intervention program on SFRP5 concentrations in children and adolescents with obesity

Koutaki Diamanto , Paltoglou George , Michos Athanasios , Bacopoulou Flora , Charmandari Evangelia

Background: Secreted frizzled-related protein 5 (Sfrp5) is a relatively novel adipokine with anti-inflammatory properties. Recent evidence suggests that it plays a role in obesity and its metabolic complications. However, data on Sfrp5 regulation in relation to obesity in children are scarce.Objective: To investigate the effect of a 1-year personalized, comprehensive, multi-disciplinary, lifestyle intervention program of...
