Background: Partial gonadal dysgenesis with a 46,XY karyotype (46,XY PGD) is a disorder of sex development (DSD) associated with abnormal development of the gonads. It is characterized by abnormally developed external genitalia with or without Mullerian structures. The degree of abnormality varies from a female phenotype with clitoral hyperplasia to a male phenotype with isolated hypospadias. The incidence is unknown. In 20-30% of patients, gonadoblastoma or i...

Usefulness of application novel TurboTM TSAb bioassay in the monitoring of pediatric Graves’ patients

Bossowski Artur , Sawicka Beata , Borysewicz-Sańczyk Hanna , Bossowski Filip , Kahaly George

Background: Thyrotropin receptor (TSH-R) stimulating autoantibodies (TSAb) are present in 95-99% of patients with Graves’ disease (GD). TSAb are functional, impact thyroid function, and are clinically relevant. This study we performed in pediatric patients with dynamic of Graves’ disease before and during methimazole therapy and in a patient with Hashimoto’s thyroiditis (HT) using a novel and ultra-rapid TSAb bioassay.<...

Assessment of regulatory B cells in peripheral blood and zinc transporter 8 expression in thyroid tissue in children with autoimmune thyroid diseases

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

Introduction: There has been a growing trend in the incidence of autoimmune thyroid diseases (ATD) in the pediatric group of patients. The new aspects of its pathogenesis may contribute to understand innovative methods of prevention and treatment. Regulatory B cells (Breg) allow the maintenance of immune homeostasis by neutralizing the negative reactions of effector cells. Attention has been recently paid also to the new environmental factor like zinc and its ...

The increasing knowledge on the functions of gastric peptides and adipokines in the body allows the assumption of their major role linking the process of food intake, nutritional status, and body growth, largely through the regulation of glucose metabolism and insulin resistance. The aim of the study was the assessment of serum levels of selected gastric peptides and adipocytokines in children with type 1 diabetes, with respect to the disease duration. The study included 88 ch...

Retrospective assessment of malignant thyroid nodules in a group of polish children and adolescents involving elastography

Borysewicz-Sańczyk Hanna , Sawicka Beata , Karny Agata , Bossowski Filip , Marcinkiewicz Katarzyna , Rusak Aleksandra , Dzięcioł Janusz , Bossowski Artur

Introduction: Thyroid nodules occur in 1.8% children which is not so often in comparison to adults (19–68%), but in children they appear to be at higher risk of malignancy (22–26% vs.5–10% respectively). It has been shown that the probability of thyroid nodules malignancy correlates with the presence of characteristic ultrasonographic features. Elastography - the noninvasive ultrasound imaging technique based on estimation of the tissue flexi...

The most common hyperthyroidism in children is Graves' disease. The other rare cause of hyperthyroidism is activating mutation in receptor TSHR in thyroid gland.We would like to introduce a case of familial hyperthyroidism with a novel mutation M453V in the TSHR in three membersActually 11-year-old boy is a patient in outpatient clinic for first days after birth. During gestation his mother was treated with thyreostatic drugs b...

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...

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...

Application of Elastography in Assesment of Different Benign Thyroid Lesions in Children and Adolescents

Borysewicz-Sańczyk Hanna , Dzięcioł Janusz , Sawicka Beata , Florczykowska Patrycja , Przychodzen Małgorzata , Bossowski Artur

Introduction: Elastography is a noninvasive imaging technique based on estimation of the tissue flexibility. There are two methods of elastography: Static Elastography and Shear Wave Elastography. Scale of deformation under pressure is presented as a colourful map – elastogram, where red colour signify soft tissues, green colour signify middle tough tissues and blue colour signify tough tissues. Analysis of elastograms enable us to present results as ROI1/ROI2 index. In a...

Analysis of Correlation between Stem Cells (CD133+/CD45+ and CD133+/CD45) and Anthropometric Parameters of Children with Growth Hormone/Primary Insulin-Like Growth Factor 1 Deficiency

Introduction: Hematopoetic progenitor stem cells (HSCs, CD133+/CD45+) and very small embryonic-like stem cells (VSELs, CD133+/CD45−) can differentiate into specific immune cells. Some studies suggest that levels of HSCs and VSELs change during therapy with growth hormone (GH) or insulin-like growth factor 1 (IGF-1). GH deficiency (GHD), an endocrine disease connected with insufficient production of GH by pituitary gland, is tre...
