Introducion: Autoimmune thyroid diseases (AITDs): Hashimoto's thyroiditis (HT) and Graves’ disease (GD) are common chronic autoimmune endocrine disorders in children. The mechanisms leading to the development of these diseases remain unknown, however scientific reports indicate that in addition to environmental factors, genetic background plays an important role. In our previous studies, we showed that some polymorphisms of the genes for IL2RA, FAIM...

Pathway to assess severe primary IGF-1 deficiency diagnosis by using the IGF-1 generation test in a real-life setting: data from the Global Increlex® Registry

De Schepper Jean , Bossowski Artur , Argente Jesús , Sert Caroline , Perrot Valérie , Pennestri Daniele , Bang Peter

Background: severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder, for which insulin-like growth factor-1 (IGF-1) generation test (IGFGT) is debated as a complementary diagnostic analysis. Diagnostic workup for SPIGFD varies geographically and diagnosis is delayed by the rarity of the condition (<1/10,000). Evaluation of real-world practices of IGFGT could help facilitate diagnosis and test use. Objective: to describe rea...

Introduction: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the Fas apoptotic inhibitory molecule 2 (FAIM2) gene, the high-affinity alpha subunit (CD25) of the interleukin-2 receptor (IL-2RA) gene, the cytotoxic T cell antigen 4 (CTLA-4) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective: To estimate...

Introduction: Angiopoietins are necessary for development, differentiation and stabilization vessels progress. Angiopoient 1 (Ang-1) is responsible for vascular integrity, through stimulation of endothelial cell migration and adhesion, and inhibition of apoptosis. Action of angiopoietin 2 (Ang-2), in the absence of VEGF it Leeds to vascular regression, but in the presence of high VEGF concentration it stimulates angiogenesis. Stromal derived factor (SDF-1) play an important ro...

Background: Forkhead box P3 (Foxp3) is an important regulatory factor for the development and function of T regulatory cells (Tregs). Moreover it has been established that deficiency of the Foxp3 gene in Treg cells suppresses their regulatory function leading to the development of autoimmune diseases especially autoimmune thyroid diseases (AITDs).Objective and hypotheses: The aim of our study was to estimate the association of three polymorphism of FOXP3...

Expression of Zinc transporter 8 in thyroid tissues from patient with immune and non-immune thyroid diseases

Bossowski Artur , Niklinska Wiesława , Gasowska Marta , Polnik Dariusz , Szalecki Mieczysław , Mikłosz Agnieszka , Chabowski Adrian , Reszec Joanna

Introduction: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. It was demonstrated that ZnT family plays an important role in the synthesis and secretion of many hormones. Moreover, recently ZnT8 was described as a newly islet autoantigen in type 1 diabetes.Materials and methods: We studied the expression of ZnT8 transporter in thyroid tissues from patients with im...

Case study of 13- year-old boy suffering from papillary thyroid cancer in stage pT3aN1bMX

Bossowski Artur , Borysewicz-Sanczyk Hanna , Stożek Karolina , Dzięcioł Janusz , Czarniecka Agnieszka , Handkiewicz-Junak Daria , Jarząb Barbara

Papillary cancer represents majority of thyroid malignancies in children. However prognosis remains very successful. In recent years, we use elastography, except biopsy and standard ultrasonography in thyroid lesions diagnostic. We present a case of a male patient at the age of 13 years, with a history of ADHD and school phobia who was referred to Endocrinology Outpatient Clinic due to partial empty sella syndrome. Family history of endocrinological disorders was negative. Ph...

Introduction: Overt clinical symptoms of type 1 diabetes (T1D) are often preceded by a pre-clinical stage of varying duration. Diagnosis of the pre-clinical stage is difficult and is based on the presence of specific islet autoantibodies in the subject's blood. Objectives: Apparently healthy first-degree relatives of patients with T1D were tested using the 3 Screen ICAELISA (RSR Ltd) for combined testing for autoantibodies to GAD65 (glutamic acid decarbox...

Introduction: Parathyroid Hormone (PTH) is one of the principal regulatory hormones for calcium and phosphate homeostasis. Reduced PTH concentration in hypoparathyroidism is characterised by hypocalcaemia and hyperphosphataemia.Case Presentation: We report a ten-year-old girl who was admitted to the Department of Paediatrics, Endocrinology, Diabetology with Cardiology due to repeated seizures, hypoalcaemia with suspected...

Introduction: Our Centre is an international referral centre for genetic analysis of children with short stature (SS) and features of GH/IGF-1 resistance. Following candidate gene and whole exome sequencing, diagnoses for ~50% patients remained elusive. Copy number variation (CNV) has not previously been investigated in GH/IGF-1 resistance and we hypothesised that CNVs contribute to the phenotype in our undiagnosed cohort.Experimental Design and Methodol...
