Background: Because of episodic secretion of gonadotropins (LH, and FSH), basal levels of these hormones can not objectively be assessed to differentiate delayed puberty in males.Objective and hypotheses: To assess the efficacy of the GnRH agonist (as spray) in diagnosing of delayed puberty in males.Method: Prepubertal males (n=18; age range 13.3–18.5 years) were studied; buserelin 0.15 (spray) μg was administere...

Aim: To determine the usefulness of priming with gonadal steroids prior to GH stimulation with clonidine in the evaluation of the GH status of short children.Method: 21 males were studied, with a mean chronological age of 13.2±1.5 years (range 11–16 years), mean bone age 11.0±1.4 years, Tanner stage 1–2, with height 135.8±7.4 cm (Ht-SDS −2.8±0.5), and an inadequate response to an initial GH stimulation test with clonid...

Objective: Prader-Willi syndrome (PWS) is a complex genetic disease associated with hypothalamic-pituitary dysfunction, severe obesity and metabolic dysfunctions. The aim of this study was to describe endocrine and metabolic profiles in PWS children and young adults.We also investigated the differences in clinical outcomes according to genotype.Methods: Data of 64 children and adults with genetically verified PWS aged mo...

Introduction: The tricho-rhino-phalangeal syndrome type 1 (TRPS 1), also known as Langer-Giedion syndrome, is an uncommon genetic disorder. This disease is characterized by short stature, cone-shaped ends of the long bones (epiphyses), and distinctive facial features linked to skeletal abnormalities since early childhood. The experience with recombinant growth hormone (rGH) therapy in TRPS 1 is relatively poor. The aim of the study is to present the results of...

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...

Background: Central diabetes insipidus (CDI) is a rare disorder in the pediatric population. CDI may be the first symptom of a brain tumor, metastatic lesions, or granulomas. The close follow-up of patients with CDI may early detect pathologic processes, especially intracranial tumors.Methods: We present four pediatric patients diagnosed with CDI of different etiology.Pat...

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...

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...

Introduction: Hashimoto's thyroiditis (HT) and Graves' disease (GD) become increasingly common in children's population. Pathogenesis of autoimmune thyroid diseases (AITD) bases on coexistence of genetic predisposition and environmental triggers which finally drive to breakdown of immune tolerance. Many mechanisms in human body moderate process of inflammation. While some of them answer for up-regulation, some agents like B regulatory lymphocytes (...

Background: Until now, altered balance of Th1 and Th2 immune cells has been postulated to play an important role in the pathogenesis of autoimmune thyroid diseases (AITD). However, recent studies on thyroid diseases have suggested a new role for Th17 cells that have been classified as a new lineage, distinct from Th1, Th2 and Treg cells. Despite wide interest, the role of Th17 cells in the pathogenesis of inflammatory and autoimmune diseases is still debated.<p class="abst...
