Novel Severe Skeletal Dysplasia with Under-Mineralisation Associated with Reduced In Utero Calcium Transport and TRPV6 Compound Heterozygous Variants

Bowen Philippa , Caswell Richard , Castle Bruce , Welch C Ross , Hilliard Tom , Smithson Sarah , Ellard Sian , Burren Christine

Background: Fetal skeletal bone development and mineralisation depends on placental calcium transfer. Although Parathyroid Hormone (PTH) pathway has some contribution, TRPV6 (the sixth member of the Transient Receptor Potential Vanilloid family) is a recently identified receptor involved in calcium transport and is predominantly expressed in the placenta. It has not previously been linked with skeletal development disorders.Case: This infant had...

DNA Methylation at a nutritionally sensitive region of the PAX8 gene is associated with thyroid volume and function in Gambian children

Candler Toby , Kessler Noah , Gunasekara Chathura , Ward Kate , James Phil , Dyer Roger , Elango Rajavel , Waterland Robert , Moore Sophie , Ludgate Marian , Prentice Andrew , Silver Matt ,

Background: Thyroid hormones contribute to a wide range of physiological processes and health outcomes. Epigenetic regulation of thyroid development and function has been little explored. PAX8 (Paired Box 8) is a thyroid transcription factor implicated in thyroid gland development and differentiation. PAX8 gene methylation appears to be sensitive to the environment in early pregnancy.Methods and Findings: Using a recall-by-epige...

Benign Breast Conditions in Adolescent Girls

Touraine Philippe

Benign breast diseases (BBD) have always been neglected in comparison to cancer, despite the fact that there are many more patients with such diseases than patients presenting to a breast clinic for cancer, especially in young women. So far, BBD have been the subject of a relatively few isolated and unconnected studies, and earlier related work has often been ignored. This situation has led to a great deal of confusion, especially because different authors have their own nomen...

The role of genetic analysis in primary ovarian failure

Touraine Philippe ,

Primary (premature) ovarian insufficiency (POI) is defined as a loss of ovarian activity before the age of 40, and is characterized by menstrual disturbances (amenorrhea or oligomenorrhea) with elevated gonadotropins (follicle-stimulating hormone [FSH] ≥ 25 IU/L) and low serum estradiol levels. The incidence of POI is around 1 per 100 women overall, and 1 per 1000 women under the age of 30 years. POI leads to infertility and an increased risk of osteoporosis and cardiova...

Long-term effectiveness and safety of childhood growth hormone treatment in Turner syndrome from two large observational studies

Backeljauw Philippe , Pietropoli Alberto , Rohrer Tilman

Patients with Turner syndrome (TS) have short stature, despite having normal growth hormone (GH) secretion. Treatment with recombinant human GH is recommended. The effectiveness and safety of Norditropin® (somatropin, Novo Nordisk) over ≤10 years of follow-up were investigated in two non-interventional studies: NordiNet® IOS (NCT00960128) and the ANSWER Program (NCT01009905). Of 2,409 children with TS, 2,377 were included in the full analysis s...

Post-Hypoglycemic Hyperglycemia Are Highly Relevant Markers For Stratification Of Glycemic Variability and Remission Status Of Pediatric Patients With New-Onset Type 1 Diabetes.

Harvengt Antoine , Pollé Olivier , Lysy Philippe

Aims: Recently, our team introduced the concept of post-hypoglycemic hyperglycemia (PHH) in the context that recovery of hypoglycemia impacts cardiovascular risk. GLUREDIA study aimed to evaluate whether PHH parameters correlated with glycemic homeostasis during the first year after type 1 diabetes onset and helped to distinguish pediatric patients undergoing partial remission or not.Methods: In the GLUREDIA study, longi...

Partial CRISPR/Cas9 IL1R1 & IFNGR1 Knock-Down Improves β-cell Survival And Function Under Cytokine-Induced Inflammation

Daems Caroline , Vanderroost Juliette , Sokal Etienne , Lysy Philippe

Type 1 diabetes (T1D) is a chronic disease characterized by the autoimmune destruction of pancreatic β cells. This destruction is mediated by lymphocytes T helper and cytotoxic, and by the action of the pro-inflammatory cytokines IL1β, IFNγ and TNFa inside the islets of Langerhans. We propose a new approach to alleviate islet inflammation by targeting pro-inflammatory cytokine receptors. Our hypothesis is that the downregulation of inflammatory pathways ma...

A Low-Carbohydrate Diet Improves Metabolic Control in a Type 1 Diabetic Child Without Side Effects

Klee Philippe , Stasinaki Aikaterini , Gozzi Tiziana , Schwitzgebel Valérie

Background and Aims: Despite intensive insulin treatment of type 1 diabetes (T1DM), metabolic control remains suboptimal, especially in children. In an attempt to optimize postprandial glycaemia, some families decrease the amount of carbohydrates contained in a meal. While "low-carbohydrate diets" may improve metabolic control in some selected populations, controversies remain around the risk of hypoglycemia and ketoacidosis and the impact of such diet...

Personalized and Predictive Medicine for Pediatric Diabetes Through a Genetic Test Using Next Generation Sequencing

Schwitzgebel Valerie , Klee Philippe , Dirlewanger Mirjam , Blouin Jean-Louis

Introduction: Monogenic diabetes (MD) accounts for at least 3% of all pediatric diabetes cases. MD is often misdiagnosed as type 1 or type 2 diabetes, because of its wide phenotypic spectrum. While clinical and biochemical parameters can suggest MD, a definitive diagnosis requires genetic analysis. We conducted a broad study to diagnose MD cases. Then, with the gained knowledge, we designed a new diagnostic to...

Comparing the Cumulative Dose of Growth Hormone Therapy Using Body Weight-Based Dosing Versus Body Surface Area-Based Dosing in Children with Turner Syndrome – Data from the ANSWER Study

Backeljauw Philippe , Geffner Mitchell , Ross Judith , Holot Natalia , Ostrow Vlady

Background and Objective: The American Norditropin Studies: Web-Enabled Research (ANSWER) Program is a long-term, US-based, non-interventional study designed to collect information on the effectiveness and safety of Norditropin® growth hormone (GH). From June 2002 to September 2016, 20,204 pediatric patients were enrolled by their treating physicians, including 1,003 patients with Turner syndrome (TS). This analysis compares cumulative GH doses when adjusting G...
