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 (...

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...

Evaluating the role of circulating dendritic cells in methimazole-treated pediatric Graves’ disease patients

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

Graves’ disease (GD) is hyperthyroidism associated with organ-specific autoimmune inflammation. GD occurs more frequently in adults than in children, however, pediatric patients are a therapeutic challenge due to cycles of remissions and relapses requiring constant monitoring at every stage of treatment administered. Dendritic cells (DCs) are considered a link between innate and adaptive immunity. DCs as antigen-presenting cells (APCs) are involved in antigen presentatio...

Effects of therapy on Th1, Th17, Th22 and Bregs in pediatric patients with Graves' disease

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

Introduction: The precise pathogenesis of Graves’ disease (GD) still remains unclear, especially in the field of immunological aspects. Thyroid infiltration by reactive T and B lymphocytes plays a crucial role in the course of autoimmune thyroid diseases (ATD). Previous pattern of inflammation process was characterized by the presence of two antagonistic groups of T effector or also called- helper cells: Th1 and Th2. Recently, more attention is paid to T...

New p.Ser237Asn Activating Mutation At The TSHR Receptor, Causing Familial Non- Autoimmune Hyperthyroidism

Bossowski Artur , Grigore Teodora , Makkonen Kristiina , Bossowski Filip , Jannari Meeri , Kero Jukka ,

Background: The pathogenesis of hyperthyroidism varies greatly, with familial non-autoimmune autosomal dominant hyperthyroidism being a rare cause. In patients who are genetically related, thyrotoxicosis develops without the clinical features of autoimmunity. In this study, we present five family members with familial hyperthyroidism who have a confirmed mutation of p.Ser237Asn in the TSHR receptor.Case Report: Our patient, a 13,5- year-...

Application of Shear Wave Elastography (SWE) in the ultrasound evaluation of thyroid nodules in children and adolescents

Borysewicz-Sańczyk Hanna , Bossowski Filip , Sawicka Beata , Michalak Justyna , Dzięcioł Janusz , Bossowski Artur

Introduction: Shear wave elastography (SWE) is an ultrasound diagnostic method used to measure tissue stiffness. Since the mechanical properties of tissue involved in the pathological process are changed, SWE might indicate regions of the examined tissue covered by the disease. It is well documented, that SWE helps differentiate benign and malignant nodules in thyroid gland in adults, however there are still few studies on application of SWE in thyroid diagnos...
