Evaluation of Toll-like Receptor 2 Expression on T Lymphocytes in Patients with Graves' Disease in Relation to the Clinical Parameters

Klatka Maria , Grywalska Ewelina , Polak Agnieszka

Introduction: Graves'disease (GD) is a polygenic and multifactorial disease.The innate immune system is a complex network of structured cells and proteins, including the Toll-like receptors (TLRs), which are also expressed on the cells of the adaptive immune system.The aim was to assess the relationship between the expression of TLR-2 on the surface of T CD4+ and CD8+ lymphocytes in pat...

Th17 Cells in Children with Graves’ Disease During Methimazole Treatment

Klatka Maria , Grywalska Ewelina , Rolinski Jacek

Background: Graves’ disease (GD) is the most common cause of hyperthyroidism in the pediatric population. T helper 17 (Th17) IL-17A+CD3+CD4+ cells represent a novel subset of T helper cells that play an active role in inflammatory and autoimmune diseases. Although methimazole (MMI) lowers the levels of thyroid autoantibodies, little is still known about its influence on cell-mediated immune response. The role of Th17 cells in GD pathogenesis remains uncertain and the impa...

The Growth Hormone Treatment and Carbohydrate Metabolism in Children Born Small for Gestational Age

Labochka Dominika , Witkowska-Sedek Ewelina , Milczarek Monika , Kucharska Anna

Background: Children who were born small for gestational age (SGA) or with intrauterine growth restriction (IUGR) have increased risk of metabolic disorders such as insulin resistance, diabetes mellitus type 2 and coronary disease in adultness. Most of those children after catch-up growth achieve the same growth as their peers. Nevertheless 10 % of them persist finally short as adults. In the last decade some countries introduced the rhGH treatment to impr...

Evaluation of ALP Value in Early Prediction of the Effects of Growth Hormone Treatment in Children with Growth Hormone Deficiency (GHD)

Witkowska-Sedek Ewelina , Kucharska Anna , Majcher Anna , Pyrzak Beata

Background: Serum bone turnover markers may serve as parameters for predicting the growth response to growth hormone (rhGH) treatment.Objective and hypotheses: Assessment of the alkaline phosphatase (ALP) value in early prediction of the effects of rhGH treatment in children with growth hormone deficiency.Method: The study group consisted of 50 children with GHD. ALP, bone-ALP, vitamin D and I...

Dysregulation of the Immune System in Children with Graves Disease – the Role of NK and NKT-Like Cells

Klatka Maria , Polak Agnieszka , Grywalska Ewelina , Kollataj Witold , Rolinski Jacek

Background: Almost all cases of hyperthyroidism in children result from Graves’ disease (GD). Recent studies have confirmed a significant role of T cells in the development of autoimmune diseases. However, the interactions between NKT-like cells and NK cells in GD are still poorly understood.Objective and hypotheses: The aim of the study was to assess the frequencies of peripheral blood T, NK and NKT-like cells in children with GD.<p class="abst...

Thyroid Function in Obese Children and Its Correlations with Chosen Atherogenic Risk Factors

Ruminska Malgorzata , Witkowska-Sedek Ewelina , Majcher Anna , Pyrzak Beata

Background: Moderately elevated thyroid-stimulating hormone (TSH) with normal serum concentrations of free thyroxine (fT4), suggesting subclinical hypothyroidism, is the most common hormonal abnormality in obese children. Controversy remains whether thyroid dysfunction related to obesity has an influence on the cardiovascular risk factors.Objective and hypotheses: The aim of the study was to assess correlation between TSH and fT4 and chosen atherogenic r...

Treatment of Graves’ Disease with Methimazole in Children Alters the Proliferation of Treg Cells and T Lymphocytes

Klatka Maria , Grywalska Ewelina , Wasiak Magdalena , Rolinski Jacek

Background: Graves’ disease (GD) is almost always the cause of hyperthyroidism in children. Studies carried out for recent years confirm an important role of T regulatory cells (Tregs) in the development of autoimmune diseases. However, the interactions between T-cell response and Treg proliferation in GD is still poorly understood.Objective and hypotheses: The aim of this research was the assessment of the in vitro proliferation of Treg ce...

Vitamin D Deficiency can Modulate GH/IGF1 Axis in GH Deficient Children

Witkowska-Sedek Ewelina , Kucharska Anna , Majcher Anna , Pyrzak Beata

Background: According to the latest studies vitamin D has an effect on the production and/or secretion of IGF1 in the liver, but the exact mechanism regulating these relationships has not been thoroughly explained.Objective and hypotheses: Evaluation of the relationship between 25(OH)D and IGF1 levels in the serum of children with GH deficiency (GHD).Method: The study group consisted of 76 GH deficient children qualified for GH the...

Influence of Birth Parameters on Growth Response and Metabolic Effects of Growth Hormone (GH) Therapy in GH-deficient Children and Adolescents

Witkowska-Sedek Ewelina , Ruminska Malgorzata , Kucharska Anna M. , Majcher Anna , Pyrzak Beata

Introduction: Growth depends on growth hormone (GH) secretion and on individual sensitivity to its action. The effects of birth parameters on growth and metabolic status are well documented in small-for-gestational-age children, but in children with GH deficiency those associations are not clear. Taking into account that GH-deficient children are not a homogenic group of patients, the importance of an individual approach to GH doses and the assessment of the e...

Acquired Severe Hypothyroidism in Children – Forgotten or Unbelievable Diagnosis in a Time of Large and Easy Availability of Thyroid Tests?

Kucharska Anna , Labochka Dominika , Borowiec Ada , Witkowska- Sedek Ewelina , Pyrzak Beata

In a time of widespread availability of thyroid lab tests plenty of patients are reported to endocrine clinics because of isolated slightly increased TSH value and many papers are dedicated disscussion of precautions to treatment in subclinical hypothyroidism. Simultaneously in the same places other patients develop severe hypothyroidism without proper diagnosis. What is the reason of missing diagnoses?The Aim: Clinical characteristics of severe hypothyr...
