Background: In adults, insulin resistance is associated with vascular damage and progressive loss of the endothelial protective functions. Additionally, it further complicates the micro- and macro- vascular environment through increasing oxidative stress and inflammation.Aim: The purpose of this study was to evaluate how apoptosis and antioxidant markers are correlated with biochemical markers in children, during the glucose tolerance te...

The Diagnostic Yield of a Targeted Next Generation Sequencing Panel in Children with Short Stature of Undefined Aetiology

Perchard Reena , Murray Philip G , Highton Georgina L , Whatmore Andrew J , Clayton Peter E

Background: Currently, data on the diagnostic yield of targeted gene panels using next generation sequencing (NGS) in children with short stature of undefined aetiology (SSUA) are limited. EPIGROW (ClinicalTrials.gov ID NCT00710307) was a prospective European epidemio-genetic study in which a targeted NGS panel including 69 genes associated with short stature (e.g. primordial growth disorders and skeletal dysplasias) was performed in 263 patients and 263 controls. In these pat...

A Boy with Diazoxide Unresponsive Congenital Hyperinsulinism due to a Homozygous ABCC8 Missense Mutation Previously Reported to be Dominant

Galcheva Sonya , Iotova Violeta , Flanagan Sarah E , Ellard Sian , Hattersley Andrew

Background: Congenital hyperinsulinism possesses considerable clinical heterogeneity attributed partly to its diverse genetic causes.Objective: To present a boy with diazoxide unresponsive hyperinsulinaemic hypoglycaemia due to a homozygous recessive ABCC8 missense mutation, previously reported to be dominant acting and being inherited by his unaffected heterozygous parents.Material and results: The boy was a third preterm child of...

In Silico and In vitro Studies of Human SRD5A2 Variants in Search for Activating Variants Explaining Androgen Excess Reveal Additional Loss of Function Variants

Katharopoulos Efstathios , Sauter Kay-Sara , Pandey Amit V , Fluck Christa E

Background: Androgens are steroid hormones necessary for human sex development. Testosterone (T) and the more potent dihydrotestosterone (DHT) are maybe the best known androgens, which exert their effect by binding and activating the androgen receptor. Steroid reductases 5α (SRD5As) catalyse the conversion of T to DHT in the classic androgen production pathway, or from 17-hydroxyprogesterone to 17OH-dihydroprogesterone, and androstenedione to androstanedione in alternate ...

Driving Paediatric Diabetes Care Forward in the UK: Improvements in Outcomes in the North West Following National Initiatives

Moore Helen S , Carson Margot E , Maiden Jonathan , Ng Sze May

Background: Type 1 diabetes mellitus (T1DM) continues to pose serious health risks with devastating long-term complications. UK management and control of T1DM in children and young people (CYP) remains amongst the poorest in Europe and significant variations in diabetes health outcomes are evident. In 2012–13 a Best Practice Tariff (BPT) for paediatric diabetes care was introduced and a National Peer Review Quality Assurance programme (DQuINS) developed. Both were develop...

Serum IGF-I, IGFBP-3 and Als Concentrations and Physical Performance in Young Swimers During a Training Season

Filho Hugo Tourinho , Pires Marcela , Puggia E F , Papoti M , Barbieri R , Martinelli Jr Carlos

Background: Exercise programs are related to the anabolic function of GH/IGF-I axis.Objective and hypotheses: To analyse IGF-I, IGFBP-3 and ALS serum concentrations in adolescent swimmers at different stages of training season, and compare them with physical performance and body composition.Method: Nine male athletes, aged 16–19 years, who trained regularly throughout the season, were studied. IGF-I, IGFBP-3 and ALS were recor...

Mir-146a and -155 are Involved in FOXO1 Regulation and Non Alcoholic Fatty Liver Disease in Childhood Obesity

Montanini Luisa , Lazzeroni Pietro , Sartori Chiara , Nobili Valerio , Crafa Pellegrino , Bernasconi Sergio , Street Maria E

Background: Non alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in childhood, in obese subjects and associated with insulin resistance.FOXO1 is a key regulator in insulin signalling and in intracellular adipogenesis, and is implicated in liver steatosis. We have previously identified that a group of miRNAs are involved in its epigenetic regulation.Objective and hypotheses: We aimed to assess in liver tissue and in serum whe...

Pro-Inflammatory (M1) and Anti-Inflammatory (M2) Profiles in Adipose Tissue of Lean and Obese Children and Adolescents

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Childhood obesity predisposes to metabolic disorders. Low grade inflammation of adipose tissue (AT) associated with macrophage infiltration may lead to metabolic complications. Two macrophage activation states M1 (pro-inflammatory) and M2 (anti-inflammatory) exist in AT with surface markers CD40 (M1), CD206 (M2) and CD163 (M2). M1 polarization correlates with metabolic complications.Objective and hypotheses: To study the expression of CD40, C...

Ex vivo Culture of Human Fetal Gonads: Manipulation of Meiosis Regulation Affects Testis Development

Jorgensen Anne , Nielsen John E , Perlman Signe , Lundvall Lene , Juul Anders , Rajpert-De Meyts Ewa

Background: Alterations in the timing or expression level of players involved in sex determination and differentiation can cause disorders of sex development, gonadal dysgenesis and germ cell neoplasms later in life. The mitosis–meiosis switch is one of the first manifestations of female sex differentiation and we hypothesise that a conflict between meiosis-inhibiting (male pathway) and meiosis-inducing signals (female pathway) is one of the possible mechanisms for disrup...

Novel Uncoupling Protein 1 Expression in White Adipocytes of Subcutaneous Abdominal Adipose Tissue in Children and Adolescents: A Protective Mechanism for Metabolic Equilibrium?

Karvela Alexia , Avgeri Aikaterini , Vlotinou Eleni D , Georgiou George , Papachristou Dionysios J , Spiliotis Bessie E

Background: Morbid childhood obesity predisposes to metabolic disorders such as diabetes type 2. In mice, heat-producing ‘brown-like’ (beige) adipocytes can suppress weight gain and metabolic disease through the action of uncoupling protein 1 (UCP1) localized in the mitochondria.Objective and hypotheses: To study the expression of UCP1 in the adipose tissue of lean&obese children and adolescents.Method: Paraffin embed...
