Adropin, Afamin And Neudesin - Novel Biomarkers of Type 1 Diabetes Mellitus in Children

Noiszewska Klaudyna , Bossowski Artur

Introduction: The incidence of type 1 diabetes mellitus (DM I) is rising. Newly discovered peptides: adropin, afamin and neudesin may play a key role in the diagnostic process in the future. Most studies assessing the relationship of those peptides provide data obtained from studies conducted on animals, adults with type DM II and women with gestational DM. There are only few studies concerning these relationships in children.Aim of the ...

Results of Mecasermin Treatment in Pediatric Patients Evaluated for Severe and Partial Primary Deficiency of IGF-1

Stozek Karolina , Bossowski Artur

Background: Severe primary deficiency of insulin-like growth factor-1 (IGFD) being characterized by growth failure and short stature in children, constitutes an indication to recombinant human IGF-1 (mecasermin) treatment. It is defined by serum insulin-like-growth factor-1 (IGF-1) levels less than or equal to 2.5 th percentile, height less than or equal to −3 S.D.S., normal growth hormone (GH) secretion and exlusion of secondary causes of IGFD.<p clas...

Analysis of Zinc-Transporter ZnT8 Autoantibodies in Children and Adolescents with Autoimmune Thyroid Diseases

Michalak Justyna , Rydzewska Marta , Bossowski Artur

Backgroud: 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.Material and methods: The study was performed in the group consisting of patients with 44 Graves’ disease (...

Change Level of TRAb in Newborn Leads to Thyroid Dysfunction – Case Report

Sawicka Beata , Borysewicz- Sanczyk Hanna , Bossowski Artur

Maternal new-diagnosed Graves’ disease is quite rare thyroid dysfunction with an estimated incidence of 0.4–1% of all pregnancies, but only 1–5% of newborns delivered to mothers with Graves’ disease develop overt clinical signs and symptoms of hyperthyroidism. Neonatal hyperthyroidism almost always is transient and results from the transplacental passage of maternal thyrotropin (TSH) receptor stimulating antibodies. Neonates born to mothers with Graves&#146...

Hyalinizing Trabecular Tumour of Thyroid Gland in 17-Year-Old Boy – Case Report

Sawicka Beata , Dzieciol Janusz , Bossowski Artur

Background: Hyalinizing trabecular tumour is a rare, begin thyroid neoplasm, which shares some histologic features with thyroid papillary carcinoma or medullary carcinoma. Sometimes it is misdiagnosed as papillary carcinoma on fine-needle aspiration cytology (FNAC). The aetiology of hyalinizing trabecular tumour is unknown. The tumour may arise in a background of chronic lymphocytic thyroiditis, multinodular goitre, or after radiation exposure. Hyalinizing trabecular adenoma (...

Genetic Susceptibility to Type 1 Diabetes in Children: Analysis of Polymorphisms rs1990760 – IFIH1, rs20541 – IL13, rs231775 – CTLA 4

Goralczyk Aleksandra , Bossowski Artur , Goscik Joanna , Wawrusiewicz-Kurylonek Natalia , Bossowska Anna , Kretowski Adam

Background: Type 1 Diabetes is influenced by genetic and environmental factors. Cytotoxic T-lymphocyte antigen 4 (CTLA-4) gene polymorphism and The interferon induced helicase domain 1 (IFIH1) gene are known to be associated with T1DM, but have not been established in a Caucasian children population yet. The interleukin 13 (IL13) gene polymorphisms impact on the development of Type 1 DM in children has not been reported yet.Objective and hypotheses: To e...

Decreased Proportions of CD4+IL17+/CD4+CD25+CD127− and CD4+IL17+/CD4+CD25+CD127-FoxP3+T Cells in Children with Autoimmune Thyroid Diseases

Bossowski Artur , Moniuszko Marcin , Grubczak Kamil , Snight Paulina , Bossowska Anna , Diana Tanja , Kahaly George

Background: Until now, altered balance of Th1 and Th2 immune cells has been postulated to play an important role in the pathogenesis of autoimmune thyroid diseases (AITD). However, recent studies on thyroid diseases have suggested a new role for Th17 cells that have been classified as a new lineage, distinct from Th1, Th2 and Treg cells. Despite wide interest, the role of Th17 cells in the pathogenesis of inflammatory and autoimmune diseases is still debated.<p class="abst...

Association of CTLA4, PADI4 and FTO Polymorphisms with Autoimmune Thyroid Diseases in Male Children

Goralczyk Aleksandra , Goscik Joanna , Wawrusiewicz-Kurylonek Natalia , Bossowska Anna , Kretowski Adam , Bossowski Artur

Background: The etiology of Autoimmune thyroid diseases (AITDs), including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT) is multifactorial and involves genetic and environmental factors. Family and population studies confirmed the strong genetic influence and inheritability in the development of AITD. Possible sex-related differences in overexpression of the cytotoxic T-lymphocyte antigen 4 (CTLA4) gene, peptidyl arginine deiminase 4(PADI4) gene, the fat mass...

Clinical Value of Thyroid-Stimulating Immunoglobulin in Paediatric Autoimmune Thyroid Diseases

Stozek Karolina , Bossowski Artur , Ziora Katarzyna , Bossowska Anna , Diana Tanja , Kahaly George J

Background: In Autoimmune Thyroid Disease (AITD) two types of TSH receptor antibodies (TSHR-Ab) may be distinguished: thyroid- stimulating immunoglobulin (TSI) that promotes the production of thyroid hormones and thyroid- blocking immunoglobulin (TBI) inhibiting the activity of TSH what leads contrarily to hypothyroidism.Objective and hypotheses: The aim of this study was to compare mean TSI and TBI levels in large paediatric cohort with AITD and control...

Analysis of Zinc Transporter ZnT8 Autoantibodies in Children and Adolescents with Autoimmune Thyroid Diseases

Bossowski Artur , Borysewicz-Sanczyk Hanna , Glowinska-Olszewska Barbara , Sawicka Beata , Bossowska Anna , Michalak Justyna , Furmaniak Jadwiga

Background: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. Moreover it was demonstrated that ZnT family plays an important role in the synthesis and secretion of many hormones. ZnT8 autoantibodies (ZnT8 Ab) next to glutamic acid decarboxylase antibodies (GAD Ab), insulin autoantibodies (IAA), and islet antigen-2 antibodies (IA-2 Ab) have been described as markers of autoimmune process ...
