[Assessment of dietary calcium intake on metabolic syndrome frequency in obese children and adolescents].

Introduction: High dietary calcium intake has an impact on reduction of adipose tissue, as in prevention and treatment of obesity and metabolic syndrome (MS). The aim of the study was to evaluate the influence of dietary calcium on appearance MS in children and adolescents.

Materials And Methods: The study included 150 patients in the age range of 7-18 years with obesity.

[Anthropometric parameters prognosticating a good final height in patients with Turner syndrome during growth hormone therapy].

Introduction: Growth hormone treatment in Turner girls is a widely accepted method of their final height improvement. However some patients do not reach satisfactory final height. The aim of the study was to evaluate the anthropometric parameters which would be prognostic for final height in children with Turner syndrome treated with growth hormone.

[Thyroid volume evaluation in girls with Turner syndrome according to normal range for healthy population].

Introduction: Turner syndrome is a common chromosomal aberration. Among other features of that syndrome susceptibility to autoimmune diseases is well known. Most often there is Hashimoto's thyroiditis.

[The influence of polymorphism the Gly972Arg variant insulin receptor substrate-1 (IRS-1) gene, and G-308A TNF-alpha gene on obesity and insulin resistance in children with obesity].

Unlabelled: Genetic factors play a role in the pathogenesis of insulin resistance in obese subjects. The insulin receptor substrate-1 (IRS-1) and IRS-2 are the most important elements of the insulin-signaling pathways, and mutations in this gene have been reported to play a role in determining insulin resistance, particulary in presence of obesity. The polymorpism of the TNF-a-308 gene is also involved in the development of obesity-related insulin resistance, therefore, we investigated whether the IRS-1 and TNF-a polymorphism can predict conversion to insulin resistance and obesity parameters in children with obesity.

[Tumor necrosis factor alpha (TNF-alpha) gene G-308A polymorphism relationship to insulin resistance and lipid abnormalities in children with obesity].

Introductions: High levels of tumor necrosis factor (TNF-alpha)-cytokine produced by adipocytes, are involved in the development of obesity-related insulin resistance and metabolic syndrome. Therefore, we investigated whether the polymorphism of TNF-alpha-308 gene can predict the conversion from insulin resistance and obesity parameters in children with obesity. THE STUDY comprised 72 children with obesity simplex (9-18 y.

[The surface CD152 (CTLA-4) expression on peripheral blood lymphocytes in children with Hashimoto's thyroiditis].

Introduction: The cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is a transmembrane molecule present on T cells that plays a critical role in the down regulation of antigen-activated immune response. Its gene polymorphism is a strong candidate gene for conferring susceptibility to thyroid autoimmunity. THE AIM of the study was to analyse the surface CTLA-4 (CD 152) expression on peripheral blood lymphocytes.

[The frequency of CTLA-4 gene polymorphism at position 49 exon 1 in children with Hashimoto's thyroiditis].

Introduction: The cytotoxic T lymphocyte antigen-4 (CTLA-4) is a molecule present on T cells that plays a critical role in the down regulation of antigen-activated immune responses. Its gene polymorphism is a strong candidate gene for conferring susceptibility to thyroid autoimmunity. THE AIM of the study was to analyse the frequency of CTLA-4 exon 1 polymorphism (A49G) in children with Hashimoto's thyroiditis.

[Assesment of the selected T and B lymphocyte subsets in children with newly diagnosed insulin-dependent diabetes mellitus].

The study was performed in 39 children with newly diagnosed insulin-dependent diabetes mellitus. The %age number of CD19+, CD5+/CD20+ B lymphocytes and CD3+, CD4+, CD8+, CD4+/DR+, CD8+/DR+ T lymphocytes subpopulations were investigated in the peripheral blood. Marked, statistically significant increase (p<0.

Changes in lymphocyte subsets in children with newly diagnosed type 1 diabetes mellitus.

Unlabelled: The aim of this study was to assess changes in selected peripheral blood lymphocyte subsets in children and adolescents with newly diagnosed type 1 diabetes mellitus (DM) and determine the correlation between these changes and other immunological markers. The study involved a group of 39 patients aged 2-14 years and a control group. The number of T- and B-lymphocytes and the number of CD4, CD8, CD4/HLA-DR, CD8/HLA-DR, CD5/CD20 subsets were measured by flow-cytometry using monoclonal antibodies.

Type 1 diabetes and prediabetic state in a monozygotic triplet.

Type 1 diabetes mellitus (IDDM) results from a chronic process of autoimmune destruction of beta cells of the Langerhans islets. The presence of autoantibodies (ICA, GADA, anti-IA2, IAA) in serum precedes the clinical onset of the disease. Genetic predisposition for IDDM is connected with HLA, CTLA-4 and insulin gene region.

Pyridinium crosslinks of collagen as a marker of bone resorption rates in children and adolescents: normal values and clinical application.

The aim of our study was to establish normal values of urinary pyridinoline (Pyr) and deoxypyridinoline (DPyr) excretion for children aged 3-18 years, examine the biological variability of the marker, and assess its clinical value for pediatric patients with growth hormone deficiency. Pyr and DPyr was measured in first void urine samples from 692 healthy subjects (340 boys, 352 girls) by high-performance liquid chromatography. At sampling, age, body height, and weight was recorded for all individuals.

Growth hormone-releasing hormone reverses secondary somatotroph unresponsiveness.

Twenty severely GH-deficient prepubertal children aged 10.7 +/- 2.1 yr (mean +/- SD) and with a height SD of -4.
