Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

Hypogonadism is represented by a hypo- and hypergonadotropic variant. Antymüllerian hormone (AMH) and inhibin B are used to assess ovarian reserve, but in pediatric practice their role has not been studied. The main interest is to conduct the study of ovarian reserve in hypogonadism among girls.Objective of the Research: To compare the content of inhibin B, AMH and estradiol in girls with hyper- and hypogonadotropic hypogonadism...

Introduction: The incidence of autoimmune thyroid diseases (ATD) is constantly rising. Graves’ disease (GD) remains the most common cause of thyrotoxicosis in pediatric population, but the exact pathogenesis of GD is still not fully understood. The immunological basis of ATD assumes an imbalance between effector and regulatory T lymphocytes. B regulatory cells (Breg) are able to suppress the pro-inflammatory properties of effector T cells. Methimazole (M...

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 ...

Background: Autoimmune thyroid disease (AITD) is the most common organ-specific autoimmune disorder. Genetic background, environmental and endogenous factors are play important roles in determining the activation of immune cells or the efficacy of the immunoregulatory pathways. Recently emphasizes the immunosuppressive role of B regulatory cells (phenotype CD19+CD24hiCD27+IL-10+, CD19+IL-10+) in regulation of immune respon...

Objective: We try to investigate the polymorphisms and amino acid variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 molecules in early-onset AITD.Methods: The genotypes of HLA-A, B, C, DRB1, DQB1, and DPB1 on AITD were analyzed in 102 Korean children with AITDs (Graves’ disease (GD)=62, Hashimoto’s disease (HD)=40) and 142 healthy control using sequence-based typing. Analysis of variant amino acids was performed across the genotyping results with ...

Background: Little is known about the pancreatic changes during type 1diabetes (T1D) progression. Recently shear wave elastography (SWE) has emerged as a tool of pancreatic stiffness assessment in chronic pancreatitis and pancreatic cancer with few studies assessing it in diabetes. Objective: to compare the pancreatic SWE in children with recent-onset and long standing T1D to healthy controls and to correlate it to diabetes-duration, glycemic control (HbA1C), ...

Background: B-Lymphocyte kinase gene (BLK) gene acts on insulin synthesis and secretion, and mapped locus on chromosome 8p23. Monogenic diabetes due to BLK gene mutation is very rare and it’s named as MODY11. We aimed to present differences in clinical, laboratory and treatment of the patients with BLK mutations.Methods: OGTT performed in six patients. A panel of 23 MODY genes was screened. Patients with BLK</e...

Background: Anti-Müllerian hormone (AMH) and inhibin B (INHB) are two hormones investigated as markers of ovarian reserve in female. serum AMH and INHB levels change through the progression of puberty, and might be markers for identifying pubertal progression rate in girls.Objective and hypotheses: To invetigate serum AMH and INHB levels as markers of pubertal progression rate in girls with central precocious puberty (CPP).Met...

Background: Transient generalized glucocorticoid hypersensitivity is a rare disorder characterized by increased tissue sensitivity to glucocorticoids and compensatory hypoactivation of the hypothalamic–pituitary–adrenal (HPA) axis. The condition itself and the molecular mechanisms that underlie its pathophysiology have not been elucidated as yet. Adenovirus 36 has been reported to cause obesity in various animal species.Objective and Hypotheses...
