Background: In premature neonates hypothyroidism or thyroid sick syndrome is frequently diagnosed, which is a result of the immaturity of the gland itself and the hypothalamic–pituitary–thyroid axis. The necessity of rapid adaptation to extrauterine life, generation of high thermal energy, and accelerated development of the central nervous system is the cause of the increased demand for thyroid hormone.Objective and hypotheses: The aim of our s...

Background: Regulatory T cells (Treg) of phenotype CD4+CD25+FoxP3+ involves active suppression of excessive immune response. The population of Treg cells from patients with type 1 diabetes (DM1) have numeric and functional abnormalities. Although there are many reports of investigations on human and animal populations, the role of regulatory T cells in the development of type 1 diabetes is still unclear.Objective and hypotheses: The aim of the study is t...

Background: Natural killer cells are a type of cytotoxic lymphocyte critical to the innate immune system. NK cells from patients with type 1 diabetes (DM1) have numeric and functional abnormalities. However, little is known about the number of NK cells in healthy siblings of children with DM1.Objective and hypotheses: The aim of the study is to compare the population of NK cells and the correlation between NK cells and beta cells autoantibody in healthy ...

Introduction: Anemia in children is still quite common, sometimes it is a secondary symptom of another rare disorder. Rendu-Osler-Weber disease, a genetically determined haemorrhagic diathesis, is characterized by the occurrence of vascular malformations leading to bleeding from the nose, skin and mucous membranes and to various internal organs. Diagnosis facilitates the occurrence of the disease in relatives of the first degree, however, due to the progressive nature of vascu...

Objective and hypotheses: The aim of the study is comparison of the occurrence of islet autoantibodies in healthy siblings of children with T1DM to healthy children from non-diabetic families.Method: Determination of anti-decarboxylase of the glutamic acid antibodies (anti GAD-Ab), anti-protein tyrosine phosphatase (anti IA2), and antibodies against zinc transporter eight (anti ZnT8) in 75 children with T1DM, their siblings – 105, and 77 healthy chi...

Background: The development of the Hashimoto’s thyroiditis is the result of the damage to thyrocytes, apoptosis, and autoimmune cytotoxic action of lymphocytes.Objective and Hypotheses: The aim of the study is to present ultrastructural changes in thyroid cells in the course of damage in Hashimoto’s thyroiditis.Method: The study involved 40 children: 20 children with Hashimoto’s thyroiditis and 20 children as a contr...

Background: Tumor necrosis factor alpha (cachexin) is a cell signaling cytokine involved in systemic inflammation process. It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. The primary role of TNF alpha is the regulation of immune cells. TNF, being an endogenous pyrogen, is able to induce fever, apoptotic cell death, an...

Background: Proper endocrine function of testicles is essential for the healthy development of children and for adult life.Methods: Hormonal profiles of patients (aged 1–18 years) were evaluated several years after surgical testicular torsion treatment. Blood samples were obtained between 11a.m and 1p.m. to measure serum levels of FSH, LH, AMH, testosterone, VEGF-A total, IGF-1, IGFBP-3 and autoantibodies against sperm and Leydig cells.<p class=...

Background: Vascular endothelial growth factor (VEGF) is a signal protein produced by cells that stimulates vasculogenesis and angiogenesis. It is part of the system that restores the oxygen supply to tissues when blood circulation is inadequate. Serum concentration of VEGF is high in bronchial asthma and diabetes mellitus. Overexpression of VEGF can cause vascular disease in the retina of the eye and other parts of the body.Objective and hypotheses: The...

Background: In autoimmune thyroiditis type Hashimoto the key role in thyrocytes destruction plays the spontaneous cytotoxic activity of T cells, and antibodies dependent mechanisms are of a less value. A spontaneous cytotoxicity is associated with the number and degree of activity of NK cells. An important role in this process plays perforin contributed in permabilization of target cells.Objective and hypotheses: The aim of the study was to evaluate the ...
