Diabetes mellitus is one of the most common chronic diseases in children. T regulatory cells (Tregs) modulate response to autoantigens and probably play a role in pathogenesis of type 1 diabetes (T1DM). The aim of the present study was the assessment of T regulatory cells including their percentages and expression of critical genes in these cells in(More)
Type 1 diabetes mellitus (T1DM) is caused by the autoimmune-mediated destruction of insulin-producing beta cells in the pancreas. T regulatory cells (Tregs) represent an active mechanism of suppressing autoreactive T cells that escape central tolerance. The aim of our study was to test the hypothesis that T regulatory cells express pro- and(More)
The metabolic syndrome (MS) is defined as a cluster of risk factors, including abdominal obesity, dyslipidaemia, glucose intolerance and hypertension, which increase the risk for coronary heart disease. The immunological aspects of obesity and MS, including the role of T regulatory cells, have been intensively investigated. The aim of this study was to(More)
INTRODUCTION Experience with use of real-time continuous glucose monitoring systems (RT-CGMS) in teenagers with diabetes type 1 is limited, and in unselected groups of young patients did not show improvement in metabolic control. AIM OF THE STUDY The objective of this study was to assess short-term RT-CGMS usage in teenagers with type 1 diabetes, in terms(More)
OBJECTIVE The low number of circulating endothelial progenitor cells (EPCs) has emerged as a biomarker of cardiovascular (CV) risk in adults. Data regarding EPCs in paediatric populations with CV risk factors are limited. The aim of the study was to estimate the EPC number and its relationship with vascular function and structure in children with type 1(More)
There has been no specific evaluation of atherogenic risk factors in children with type 1 diabetes mellitus (T1DM) treated with continuous subcutaneous insulin infusion (CSII). We, therefore, studied the prevalence of overweight/obesity and metabolic syndrome among these patients. Five hundred children with T1DM treated with CSII and multiple daily insulin(More)
The aim of the study was to evaluate the function of monocytes in children with leukemias and lymphomas based on the expression of critical costimulatory, activatory and adhesion molecules (CD80, CD86, HLA-DR and CD54 = ICAM-1), estimated with tricolor flow cytometry. In comparison to the control group we found a lower percentage of monocytes with(More)
The objective of this study was to investigate the vascular status, left-ventricular mass and biomarkers of endothelial activation in hypertensive (HT) adolescents, with particular attention to comparing nonobese with obese patients. Seventy-nine newly diagnosed HT adolescents aged 15.1±2.1 years (divided into 34 nonobese and 45 obese) were compared with 35(More)
OBJECTIVE We aimed to determine the prevalence of excess body mass in juvenile idiopathic arthritis (JIA) children and to investigate the influence of obesity into the early, subclinical changes in cardiovascular system in these patients. METHODS Fifty-eight JIA patients, aged median 13 years, were compared to 36 healthy controls. Traditional(More)
BACKGROUND A potential role of preproghrelin polymorphisms on autoimmune thyroid diseases (AITDs) has not been established equivocally yet. AIM To estimate the association of two polymorphisms of preproghrelin gene with the predisposition to Graves' disease (GD) and Hashimoto's thyroiditis (HT) in children. METHODS The study was performed in 145(More)
