Alterations in DNA Methylation Status of Gene Promoters in Children and Adolescents with Autoimmune Thyroid Disease

Kyrgios Ioannis , Fragkou Aikaterini , Efraimidou Smaragda , Tzimagiorgis Georgios , Emporiadou-Petikopoulou Maria , Galli-Tsinopoulou Assimina

Background: Hashimoto Thyroiditis (HT) and Graves Disease (GD) are conditions known to be caused by abnormal immune response against self-tissues. The biological processes at molecular lever are still poorly understood. A few epigenetic studies have been published so far.Objective: To investigate whether there are differences in DNA methylation within the HLADRB1, CD40L, FOXP3, CTLA4, FCRL3, IL2RA and PTPN22 promoters between young patients with autoimmu...

Expression of ZnT8 Transporter in Thyroid Tissues from Patients with Immune and Non-Immune Thyroid Diseases

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

Introduction: Zinc homeostasis is regulated by ZnT and Zip zinc transporters. Zinc transporter 8 (ZnT8) is localized in insulin containing secretory granule membrane and transports zinc from the cytosol into the vesicles. ZnT8 was identified on peripheral lymphocytes, in subcutaneous adipose tissue, in a pancreatic β-cells and extra-pancreatic endocrine glands including pituitary, adrenal and thyroid. Autoantibodies to the ZnT8 are detected in the majority of type 1 diabe...

The Reference and Follow-up Signs and Symptoms of the Cases Who Are Diagnosed As Hyperthyroidism

Gokce Demir Elif , Guven Ayla , Yildiz Metin

Objective: Hyperthyroidism is rarely seen in the childhood. In this study, we evaluated the reference sign and symptoms and following laboratory and treatment results of the hyperthyroidism cases.Method: Data of the 78 patients were extracted from hospital records retrospectively. Patients’ height, weight, BMI and laboratory results at the time of diagnosis are recorded. Antithyroid drug doses at the 2th, 6th, 12th months after diagnoses are compare...

Evaluation of the Usefulness of Serum Cytokines IL-1β and sFasL Measurements in the Diagnosis of Autoimmune Hypothyroidism and Hyperthyroidism in Children

Mikos Hanna , Mikos Marcin , Niedziela Marek

Background: Autoimmune thyroid diseases (AITD) are one of the most common organ-specific autoimmune disorders, of which Hashimoto’s thyroiditis (HT) and Graves’ disease (GD) are 2 of the most common clinical expressions. HT is characterized by hypothyroidism (hypoT) that results from the destruction of the thyroid by specific T cell-mediated cytotoxicity. In contrast, GD is characterized by hyperthyroidism (hyperT) induced by thyrotropin receptor-specific stimulatory...

Background: Graves disease is the most common cause of hyperthyroidism in children. The frequency of the disease increases with age, peaking during adolescence.Thyroid storm is a rare but critical, ilness that can lead to multiorgan failure and carries a high death rate. Antithyroid drugs are usually recommended as the initial treatment and are generally well tolerated. Although current treatment options include radioactive iodine, but long term complications of thyroid irradi...

Transition for Patients with Chronic Thyroid Diseases

Ratnasabapathy Piriya , Bouthors Thérèse , Antoniou Maria-Christina , Stoppa-Vaucher Sophie , Elowe-Gruau Eglantine , Busiah Kanetee , Hauschild Michael

Background: Children and adults with chronic thyroid disorders (TD) need continuous monitoring as periods of inadequate thyroid hormone substitution can impact metabolism, puberty and fertility. Transition from pediatric to adult-oriented care is often characterized by discontinuity in care resulting in poor health outcomes and impaired quality of life. Transition care (TC) for young adults with TD remains largely unknown.Objecti...

Anti-Gastric Parietal Cells Antibodies for Autoimmune Gastritis Screening: A Follow-Up Study in Young Patients with Autoimmune Thyroid Disease.

Calcaterra Valeria , Montalbano Chiara , Vinci Federica , Miceli Emanuela , Regalbuto Corrado , Albertini Riccardo , Larizza Daniela

Introduction: The association between ATD and AIG is very poorly characterized in pediatric age. We review the prevalence of the anti-gastric parietal cells antibodies (APCA) in young patients with ATD and we evaluated the development of AIG during follow-up, in order to define the usefulness of these markers for AIG screening in these patients.Patients and Methods: We evaluated 220 children and adolescents (11.28 ±...

Thyroid Autoimmunity in Children and Adolescents with Type 1 Diabetes Mellitus

Selveindran Nalini M , Wong SL Jeanne , Hong Janet YH , MZ Fuziah

Introduction: Type 1 diabetes mellitus (T1DM) is commonly associated with other organ – specific autoimmune disorders. Autoimmune thyroid disease (AITD) is the most common comorbid autoimmune condition in patients with T1DM. The occurrence of both T1DM and AITD is defined as Autoimmune Polyglandular Syndrome type 3 variant (APS3v). We sought to clarify thyroid autoimmunity in a cohort of Malaysian patients with T1DM.Methods<...

Analysis of Diabetes-Associated Autoantibodies in Children and Adolescents with Autoimmune Thyroid Diseases

Bossowski Artur , Rydzewska Marta , Michalak Justyna , Bossowska Anna , Chen Shu , Black Sarah , Powell Michael , Furmaniak Jadwiga , Smith Bernard Rees

Background: Zinc transporter 8 autoantibodies (ZnT8Abs) together with glutamic acid decarboxylase autoantibodies (GADAbs), insulinoma antigen 2 autoantibodies (IA-2Abs) and insulin autoantibodies (IAbs) are markers of type 1 diabetes mellitus (T1DM). We studied the prevalence of ZnT8Ab in children with autoimmune thyroid diseases (AITDs) to assess the association of AITDs and T1DM at the serological level.Methods: The st...

Analysis of Chosen Polymorphisms rs7138803 A/G - FAIM2, rs7093069 C/T - IL-2RA, rs5742909 C/T - CTLA-4 in Pathogenesis of Hashimoto’s Thyroiditis in Children

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...
