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...

A 14-Year-Old Boy with Simpson-Golabi-Behmel Syndrome – Case Report

Sawicka Beata , Jakubiuk-Tomaszuk Anna , Borysewicz- Sańczyk Hanna , Michalak Justyna , Bossowski Artur

Simpson-Golabi-Behmel syndrome is a condition which classified as an overgrowth syndrome and affects many parts of the body and occurs primarily in males. Infants have macrosomia at birth and continue to grow and gain weight at an unusual rate. The incidence of Simpson-Golabi-Behmel syndrome is unknown. Mutations in the GPC3 gene are the most common cause of Simpson-Golabi-Behmel syndrome. About 250 people worldwide have been diagnosed with this disorder. About 10 percent of p...

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...

Identification of Zinc Transporter ZnT8 in Thyroid Tissues from Children and Adolescents with Thyroid Nodular Hyperplasia

Bossowski Artur , Niklinska Wieslawa , Gasowska Marta , Goralczyk Aleksandra , Polnik Dariusz , Reszec Joanna

Background: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. It has been demonstrated that the ZnT family plays an important role in the synthesis and secretion of different hormones. Furthermore, ZnT8Ab (zinc transporter-8 autoantibodies) together with GADAb (glutamic acid decarboxylase antibodies), IAA (insulin autoantibodies) and IA-2Ab (islet antigen-2 antibodies) are markers of auto...

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 ...

Assessment of Omentin-1, Vaspin, and Visfatin Levels in Pediatric Patients with GH Deficiency

Sawicka Beata , Borysewicz-Sanczyk Hanna , Zasim Aneta , Jakubowska Ewa , Bossowski Artur

Introduction: GH deficiency (GHD) is a disease, in which the pituitary gland does not produce enough GH. GHD has a variety of different negative effects at different ages; e.g. it can result short stature and increased adiposity. Excessive intra-abdominal fat is associated with an increased risk of cardiovascular disease. In recent years new adipokines such as:omentin-1, vaspin, and visfatin have been described. Omentin-1 is decreased in obesity in contrast to increased vaspin...

Hypothalamic Hamartoma as a Cause of Central Precocious Puberty in 4.5-Year-Old Girl: Case Report

Jakubowska Ewa , Sawicka Beata , Borysewicz-Sanczyk Hanna , Zasim Aneta , Bossowski Artur

Background: Hamartoma is a benign, focal malformation, which is composed of tissue elements normally found at that site which are arranged chaotically within the mass. It may occur in many different parts of the body and often is undetected. Hypothalamic hamartoma, unlike most such growths, is symptomatic. It may cause gelastic seisures, visual problems, rage disorders and early onset of puberty.Objective and hypotheses: A 4.5-year-old girl was hospitali...

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

Background: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene, the interferon induced helicase domain 1 (IFIH1) gene, the TSH receptor (TSH-R) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association...
