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...

Analysis of Chosen Polymorphisms rs2476601 A/G – PTPN22, rs1990760 C/T – IFIH1, rs179247 A/G – TSHR in Pathogenesis of Autoimmune Thyroid Diseases in Children

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...

Analysis of Chosen Polymorphisms rs5742909 C/T – CTLA4, rs7522061 C/T – FCRL3, rs7138803 A/G – FAIM2 in Pathogenesis of Autoimmune Thyroid Diseases in Children

Jakubowska Ewa , 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 cytotoxic T-lymphocyte-associated protein 4 (CTLA4) gene, Fc receptor-like 3 (FCRL3) gene, Fas apoptotic inhibitory molecule 2 (FAIM2) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association of polymorphi...

The Association between TSHR, IFIH1 and ETV5 Polymorphisms with Graves’ Disease and Diabetes Mellitus Type 1 in Children

Stozek Karolina , Wawrusiewicz-Kurylonek Natalia , Goscik Joanna , Wasniewska Malgorzata , Aversa Tommaso , Corica Domenico , Kretowski Adam , Bossowski Artur

Background: Many organs of human body are attacked by autoimmune processes and countless number of genes are involved in their pathogenesis. Diabetes mellitus type 1 (T1DM) attaching pancreas is a common autoimmune disease in childhood. Among autoimmune thyroid diseases (AITD) we can distinguish less frequent in children population- Graves’ disease (GD). Thyroid stimulating hormone receptor (TSHR) gene encodes membrane protein responsible for thyroid metabolism. Interfero...

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...

The Comparison of the Occurrence of Beta Cells Autoantibody and Regulatory T Cells (CD4+CD25+FoxP3+) in Patients with Type 1 Diabetes Mellitus, their Siblings and Healthy Children

Sieniawska Joanna , Krzewska Aleksandra , Ben-Skowronek Iwona

Background: Regulatory T cells (Treg) of phenotype CD4+CD25+FoxP3+ involves active suppression of excessive immune response. The population of Treg cells from patients with type 1 diabetes (DM1) have numeric and functional abnormalities. Although there are many reports of investigations on human and animal populations, the role of regulatory T cells in the development of type 1 diabetes is still unclear.Objective and hypotheses: The aim of the study is t...

The Comparison of the Occurrence of Beta Cells Autoantibody and Natural Killer Cells in Patients with Type 1 Diabetes Mellitus, Their Siblings and Healthy Children

Sieniawska Joanna , Krzewska Aleksandra , Ben-Skowronek Iwona

Background: Natural killer cells are a type of cytotoxic lymphocyte critical to the innate immune system. NK cells from patients with type 1 diabetes (DM1) have numeric and functional abnormalities. However, little is known about the number of NK cells in healthy siblings of children with DM1.Objective and hypotheses: The aim of the study is to compare the population of NK cells and the correlation between NK cells and beta cells autoantibody in healthy ...

Ovarian Reserve Assessment in Girls and Women after Hematopoietic Stem Cell Transplantation Treatment Underwent in Childhood

Wedrychowicz Anna , Wojtys Joanna , Starzyk Jerzy B.

Background: Hypogonadism is one of the most frequent endocrine complication after hematopoietic stem cell transplantation (HSCT). In some patients hypogonadism could be transient, but very often coexists with prematury ovarian failure. Classical methods used in the diagnostics of hypogonadism have limitations for the prognosis of ovarian reserve.Objective: The aim of the study was to assess ovarian reserve in patients after HSCT using ev...
