Genetic Engineering Using TALENs to Study the Redox Regulation of Steroidogenesis in vivo

Griffin Aliesha , Parajes Silvia , Taylor Angela , Mueller Ferenc , Krone Nils

Background: Transcription activator-like effects nucleases (TALENs) have recently been developed as an efficient method for in vivo genome engineering. Zebrafish are becoming an increasingly popular model to study translational aspects in endocrinology. The redox cofactor ferredoxin (FDX1) is essential for mitochondrial cytochrome P450 (CYP) enzymes including those required for steroidogenesis. In vitro, FDX1 modifications influence the catalytic rate of ster...

Atypical Presentation of Six Patients with Mutations in the Side Chain Cleavage Enzyme CYP11A1

Chan Li , Huebner Angela , Spoudeas Helen , Cheetham Tim , Metherell Louise

Background: Mutations in the side chain cleavage enzyme, (CYP11A1) cause congenital adrenal insufficiency, with complete or partial 46XY sex reversal. The disorder manifests with adrenal and gonadal insufficiencies along with derangements of the renin/angiotensin system.Objective and hypotheses: To obtain a genetic diagnosis in six patients with adrenal insufficiency of unknown aetiology. Patients 1 and 2 are sisters with ACTH resistance, having...

Adrenal insufficiency masquerading as biliary atresia in an infant

Hashim Raihana , Senanayaka Ayodya , Kiriwaththuduwa K S U , Vass Angela ,

Background: Adrenal insufficiency is a rare cause of neonatal cholestasis, which is reversible with prompt glucocorticoid administration.Case presentation: A 2-month old baby boy was referred to the paediatric endocrine department for evaluation of intermittent hypoglycaemia associated with metabolic acidosis, hyponatraemia and hyperkalaemia. The infant was second born to second-degree consanguineous parents whose first...

Insulin secretion defect in children and adolescents with obesity: Clinical and molecular genetic characterization

Enders-Seidlitz Helena , Raile Klemens , Galler Angela , Wiegand Susanna

Introduction: Childhood obesity shows increasing numbers worldwide and presents as a global health issue due to multiple metabolic comorbidities. About 1 % of adolescents with obesity develop type 2 diabetes (T2D), however little is known about the genetic and pathophysiological background in young age. Genome-wide association studies in adults revealed genes with increased diabetes risk, most of them regulating insulin secretion. The objective of this study w...

Age at diagnosis of XLH amongst children with and without a family history: Findings from the International XLH Registry

Uday Suma , Sandilands Kerry , Williams Angela , Mughal M.Zulf

Background: X-linked hypophosphatemia (XLH) is a rare, progressive, genetic phosphate wasting disorder leading to rickets, lower limb deformities as well as short and disproportionate stature. The condition is inherited in the majority, however spontaneous mutations are reported in ≈30% of cases. Its rarity, coupled with its diverse clinical manifestations, may lead to delayed diagnosis and subsequently delayed treatment initiation. The objective of this an...

Telemedicine usefulness in the follow-up of young people with diabetes 1 diabetes 2-years after the spread of COVID-19

Predieri Barbara , Candia Francesco , Stefanelli Francesca , Vandelli Sara , Lucaccioni Laura , Bruzzi Patrizia , Iughetti Lorenzo

Introduction: Telemedicine was adopted during the lockdown due to the COVID-19 pandemic in the follow-up of patients with type 1 diabetes (T1D). Because of its potential to reinforce self-management support outside health care settings it was used still after the lockdown.Objectives: Longitudinal and observational study aimed to investigate effectiveness of telemedicine in the follow-up of young people with T1D over the ...

Sensitivity to thyroid hormones and cardiometabolic risk in euthyroid obese children: a cross-sectional study.

Tropeano Angelo , Corica Domenico , Lorenza Curatola Selenia , Li Pomi Alessandra , Alibrandi Angela , Pepe Giorgia , Aversa Tommaso , Wasniewska Malgorzata

Background: The typical biochemical phenotype related to obesity, that is high serum thyrotropin (TSH) within normal range, low/normal free thyroxine (FT4) and increased free triiodothyronine (FT3) levels, can be interpreted as a resistance to thyroid hormones. It is unclear the role played by thyroid hormones in the pathogenesis of metabolic derangement associated with obesity.Aim: To investigate the association between...

Serum endocan as a predictive biomarker of cardiovascular risk in obese pediatric patients

Curatola Selenia , Mandraffino Giuseppe , Morace Carmela , Scuruchi Michele , Serrano Angela Elvira , Tropeano Angelo , Wasniewska Malgorzata , Valenzise Mariella ,

Introduction: Endocan is a soluble dermatan sulfate PG (50kDa), composed by 165 amino acid core protein, that is expressed and secreted by endothelial cells of dermal microvasculature, coronary, pulmonary arteries, and capillaries from adipose tissue. It plays an important role in the pathogenesis of vascular disorders, inflammation, and neoangiogenesis. Endocan biosynthesis is upregulated by inflammatory cytokines like TNF-α,IL-1, TGF-β1, and by pro...

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...

Tailored daily transdermal testosterone treatment before hypospadias surgical repairing: preliminary data of a single center study

Lucaccioni Laura , Insalaco Anna , Vandelli Sara , Ghidini Filippo , Trevisani Viola , F. Madeo Simona , Luca Ceccarelli Pier , Iughetti Lorenzo

Background: Hypospadias is one of the most common congenital anomalies in males. Surgical repairing aims to improve the aesthetic and functional outcome. The success rate of hypospadias repairing is variable according to the severity of the malformation with a complication rate(CR) of almost 60% in proximal forms. Testosterone treatment before surgery is still controversial and its impact on surgical outcomes, and the best regimen for administration, is unclea...
