Recent research implies a role of decreased number and/or function of T-regulatory cells (Tregs) in low-grade inflammation associated with obesity and atherosclerosis. The enhancement of atheroprotective immunity by the expansion of Tregs could serve as a therapeutic strategy in obesity-related immunological disturbances. The aim of our study was an attempt(More)
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)
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)
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)
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)
UNLABELLED Despite discovery of new therapeutic agents, including nucleoside analogs and monoclonal antibodies, the B-cell chronic lymphocytic leukemia (B-CLL) remains incurable. In recent years, some effort has been made in developing T-cell specific immunity against neoplasmatic cells. Reconstitution of effective costimulation and immunological response(More)
The highest annual increase in the incidence of type 1 diabetes (T1D) in children under the age of 5 years and aggressive process of β-cell destruction in this age group indicate the need to assess the immune system. The aim of this study was to evaluate regulatory T cells (Tregs) frequency in the peripheral blood of children <5 years of age with newly(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)
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)
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)
