Krzewska Aleksandra , Sieniawska Joanna , Ben-Skowronek Iwona

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...

Ovarian Reserve Assessment in Girls and Women after Hematopoietic Stem Cell Transplantation Treatment Underwent in Childhood

Wedrychowicz Anna , Wojtys Joanna , Starzyk Jerzy B.

Background: Hypogonadism is one of the most frequent endocrine complication after hematopoietic stem cell transplantation (HSCT). In some patients hypogonadism could be transient, but very often coexists with prematury ovarian failure. Classical methods used in the diagnostics of hypogonadism have limitations for the prognosis of ovarian reserve.Objective: The aim of the study was to assess ovarian reserve in patients after HSCT using ev...

Prediction of First Year Response to Growth Hormone Treatment in Neural Network Models

Smyczynska Urszula , Smyczynska Joanna , Hilczer Maciej

Background: Accurate prediction of responsiveness to growth hormone (GH) therapy is an important issue. The 1st year response to treatment is regarded as significant predictor of the attained final height. Neural networks are techniques of machine learning which do not require any assumptions and preprocessing of data, contrary to linear regression models.Objective and hypotheses: The aim of the study was to predict height velocity (HV) during 1st year o...

Severe IGF-I Deficiency in Children with Normal Growth Hormone (GH) Secretion and Excluded GH Insensitivity – is it Really Idiopathic Short Stature?

Joanna Smyczynska , Urszula Smyczynska , Andrzej Lewinski , Maciej Hilczer

According to current recommendations, children with height SDS <-3.0, normal growth hormone (GH) peak in stimulation tests (stimGH) and severe IGF-I deficiency (IGFD) may be diagnosed with primary IGFD and treated with recombinant IGF-I. The need for direct confirmation of GH insensitivity is a matter of discussion. On the other hand, children born small for gestational age (SGA) with no catch-up growth are qualified to GH therapy despite normal GH secretion. The fact that...

Tumor Necrosis Factor Alpha in Metabolic Syndrome Development in Children

Ben-Skowronek Iwona , Kapczuk Iga , Mroczek Wacinska Joanna

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...

Hormonal Predictors of Growth Hormone Therapy Effectiveness in Children with Short Stature – Evidence from Neural Prediction Model for Final Height

Hilczer Maciej , Smyczynska Joanna , Urszula Smyczynska , Stawerska Renata , Lewinski Andrzej

Prediction of growth hormone (GH) therapy effectiveness in children with short stature is an important issue for optimizing its course. Recently, our research group has published prediction models derived with neural networks. The main predictors of final height (FH) in our model were: patient’s height SDS at therapy onset, pre-treatment change of height SDS (HSDS V0) and pre-treatment IGF-I and IGFBP-3 secretion but not the results of GH stimulation tests; the...

Predictors of Poor Response to Growth Hormone Therapy in Children with Short Stature – Evidence from Neural Prediction Model for Final Height

Smyczynska Joanna , Smyczynska Urszula , Hilczer Maciej , Stawerska Renata , Lewinski Andrzej

Prediction of poor response to growth hormone (GH) therapy in children with short stature is an important issue for personalized approach to treatment. Recently, our research group has published prediction models derived with neural networks. The main predictors of final height (FH) in our model were: patient’s height SDS at therapy onset (H0SDS) and pre-treatment IGF-I and IGFBP-3 concentrations but not the results of GH stimulation tests; pre-treatment growth...

Assessment of Ovarian Reserve in Young Women with Hashimoto Disease – The Pilot Study

Wedrychowicz Anna , Wojtyś Joanna , Stelmach Malgorzata , Starzyk Jerzy B

Introduction: Human ovary is commonly the target of an autoimmune attack in cases of organ- or non-organ-specific autoimmune disorders. Hashimoto’s thyroiditis (HT) is likely to be associated with ovarian dysfunction and diminished ovarian reserve. The classical hormonal test assessing ovarian reserve as early follicular phase serum levels of FSH, inhibin B and estradiol (E2), which are interdependent, and the calculation of the number of antral follicles by transvaginal ...

Expression of ZnT8 Transporter in Thyroid Tissues from Patients with Immune and Non-Immune Thyroid Diseases

Bossowski Artur , Reszec Joanna , Polnik Dariusz , Gasowska Marta , Niklinska Wieslawa

Introduction: Zinc homeostasis is regulated by ZnT and Zip zinc transporters. Zinc transporter 8 (ZnT8) is localized in insulin containing secretory granule membrane and transports zinc from the cytosol into the vesicles. ZnT8 was identified on peripheral lymphocytes, in subcutaneous adipose tissue, in a pancreatic β-cells and extra-pancreatic endocrine glands including pituitary, adrenal and thyroid. Autoantibodies to the ZnT8 are detected in the majority of type 1 diabe...

Significance of IGF-I Generation Test in Diagnosing Primary and Non-Primary IGF-I Deficiency – Clinical Considerations

Smyczynska Joanna , Smyczynska Urszula , Stawerska Renata , Lewinski Andrzej , Hilczer Maciej

Background: The diagnosis of severe primary IGF-I deficiency (IGFD) in children with normal growth hormone (GH) peak in stimulation tests (stimGH) should be confirmed by IGF-I increase <15.0 ng/ml during generation test (IGF-GT), however the significance of IGF-GT has been questioned by some researchers.Objective and hypotheses: Evaluation of the significance of IGF-GT in children with normal stim GH and IGFD, with respect to efficacy of growth-promo...
