Effects of methimazole therapy on effector T and B regulatory cells in pediatric patients with Graves' disease

Stożek Karolina , Grubczak Kamil , Starosz Aleksandra , Bossowski Filip , Moniuszko Marcin , Bossowski Artur

Introduction: The incidence of autoimmune thyroid diseases (ATD) is constantly rising. Graves’ disease (GD) remains the most common cause of thyrotoxicosis in pediatric population, but the exact pathogenesis of GD is still not fully understood. The immunological basis of ATD assumes an imbalance between effector and regulatory T lymphocytes. B regulatory cells (Breg) are able to suppress the pro-inflammatory properties of effector T cells. Methimazole (M...

Thyrotropin receptor stimulating antibodies in pediatric patients with Graves’ diseases using ultra-rapid turbo bioassay

Bossowski Artur , Hatun Burak , Sawicka Beata , Stożek Karolina , Bossowski Filip , J Kahaly George

Background: Thyrotropin receptor (TSH-R) stimulating autoantibodies (TSAb) are present in 90-100% of patients with Graves’ disease (GD). TSAb are functional, impact thyroid function, and are clinically relevant. This study we performed in a pediatric patients with dynamic of Graves’ disease before and during methimazole therapy and in patient with Hashimoto’s thyroiditis using a novel and ultra-rapid TSAb andTBAb bioassay.<p class="abstex...

Change in timbre of voice as one of the signs of hyperandrogenism in a 11-year-old girl- a case report

Sawicka Beata , Szarras-Czapnik Maria , Borysewicz-Sanczyk Hanna , Michalak Justyna , Stozek Karolina , Bossowski Artur

Background: Partial gonadal dysgenesis with a 46,XY karyotype (46,XY PGD) is a disorder of sex development (DSD) associated with abnormal development of the gonads. It is characterized by abnormally developed external genitalia with or without Mullerian structures. The degree of abnormality varies from a female phenotype with clitoral hyperplasia to a male phenotype with isolated hypospadias. The incidence is unknown. In 20-30% of patients, gonadoblastoma or i...

A single centre experience of aromatase inhibitors to limit bone age advancement in pre-pubertal boys with adrenal disorders causing androgen excess

Shaunak Meera , Zichichi Giulia , Peters Catherine , Brain Caroline , Dattani Mehul

Introduction: Anastrozole, an aromatase inhibitor, prevents the conversion of androgen to oestrogen, which is required for the adolescent growth spurt and the attainment of peak bone mass. Anastrozole may help minimise bone age (BA) advancement in conditions associated with adrenal androgen excess, such as congenital adrenal hyperplasia (CAH) and premature adrenarche.Objectives: 1. To describe baseline characteristics an...

Global Increlex® Registry, post-authorisation surveillance registry monitoring the long-term safety and effectiveness of mecasermin in children and adolescents with Severe Primary IGFD (SPIGFD): objectives and study design

Bang Peter , Mazain Sarah , Perrot Valérie , Sert Caroline

Background: Severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder characterised by severe short stature. Replacement therapy with recombinant human IGF-1 (rhIGF-1; mecasermin [Increlex®]) is currently the only available treatment for children/adolescents with SPIGFD. We describe the methodology of the Global Increlex Patient Registry (NCT00903110), designed to monitor long-term safety and effectiveness of meca...

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...

Characteristics, Effectiveness and Safety Data from Clinically Relevant Subgroups of Patients with Severeprimary IGF-I Deficiency (SPIGFD): Results from the European Increlex® Growth Forum Database (EU-IGFD) Registry

Woelfle Joachim , Polak Michel , Perrot Valerie , Sert Caroline , Bang Peter

Background: The EU-IGFD registry was established to monitor the safety and effectiveness of recombinant human IGF-I (rhIGF-I) (mecasermin (rDNA origin) injection; Increlex®) for short stature in children with SPIGFD, including those with Laron syndrome (LS).Objective: To report patient characteristics, effectiveness and safety data in clinically relevant patient subgroups.Methods: Data were compiled from this ongoin...

An Irish Regional Study of Paediatric Growth Hormone Deficiency (CO-GHD): Classification of Causes and Factors Associated with Persistent GHD at Transition

Grace Mariana , Joyce Caroline , Morissey Rose , Moore Michael , O'Connell Susan

Childhood-onset growth hormone deficiency (CO-GHD) is topical at present due to the increasing understanding of underlying genetic aetiologies, influence on childhood growth, and future effects on adolescence and adult health. There is no previous Irish data of this group of children.Methods: A retrospective cohort study over 2 years (2013-2015) including all children diagnosed with GHD who received recombinant growth hormone treatment (rGH). Predictors ...

A De Novo Missense Mutation in the 4th Zinc Finger of the WT1 Gene Causes 46,XY and 46,XX DSD in Two Sibs

Bertalan Rita , Gellen Balazs , Eozenou Caroline , McElreavey Kenneth , Bashamboo Anu

The WT1 gene has a crucial role in the genesis of the bipotential genital ridge and subsequently in the specification of the Sertoli cells of testis. Mutations involving the WT1 gene are associated with a wide range of phenotypes impacting testis-determination and development including Denys-Drash syndrome, Frasier syndrome and Meacham syndrome. Here, we describe two sibs with DSD carrying a de novo mutation in the WT1 gene. A girl was born with Prader IV intersex genitals. Cy...
