The Association between rs4684677 T/A Polymorphism in Preproghrelin Gene And predisposition to Autoimmune Thyroid Diseases in Children*

Bosswski Artur , Moniuszko Anna , Wawrusiewicz-Kurylonek Natalia , Bossowska Anna , Jakubowska Ewa , Kretowski Adam

Background: Ghrelin and obestatin are two gastrointestinal peptides obtained by post-translational processing of a common precursor, preproghrelin. mRNA expression for preproghrelin was found in autoimmune thyroid diseases (AITDs) in previous studies. There are papers, where a role of preproghrelin polymorphism on various immunological diseases was determined, but nothing is known about its influence on the AITDs.Objective and hypotheses: The aim of our ...

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 (...

Non-Invasive Measurements of Central Blood Pressure with Arterial Stiffness Indicators as a New Research Tool for Predicting Cardiovascular Risk in Children with Type 1 Diabetes Mellitus and Obesity

Noiszewska Klaudyna , Puchalski Mateusz , Skolimowska Anna , Bossowski Artur

Introduction: The main problem of contemporary diabetology is to prevent chronic complications of carbohydrate metabolism disorders according to DM1 and obesity (pre-disposing for DM2). The task is to find simple tools that allow rapid identification of vascular lesions and early treatment intervention.Aim of the study: The aim of the study was to evaluate parameters of CBP in patients with DM1 and obesityMaterials and methods: The...

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...

15-Year Old Girl with APS Type IIIc, with Post-Thymectomy Remission – Case Report

Bossowski Artur , Jamiolkowska Milena , Furmaniak Jadwiga , Smith Bernard Rees

Background: Autoimmune polyglandular syndromes (APS) is a group of heterogeneous conditions characterized by the association of at least two organ-specific disorders, concerning both endocrine and non-endocrine organs. On the basis of the clinical features, they are divided into four main types. Type III is defined as the combination of autoimmune thyroid disease and other autoimmune condition – divided into subtypes A, B and C.Objective and hypothe...

Alterations in stem cell populations during rIgF-1 (Increlex) therapy in patients with SPIGF1D

Bossowski Artur , Grubczak Kamil , Stożek Karolina , Starosz Aleksandra , Bossowski Filip , Moniuszko Marcin

Pathway involving insulin-like growth factor 1 (IGF-1) plays significant role in growth and development. Crucial role of IGF-1 was discovered inter alia through studies involving deficient patients with short stature, including SPIGFD individuals. Noteworthy, despite disturbances in proper growth, elevated values for selected stem cell populations were found in IGF-1 deficient patients. Therefore, here we focused on investigating role of these cells - very small embryonic-like...
