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

Background: Prediction of the effectiveness of GH therapy in children with short stature is an important issue. Artificial neural networks (ANN) seem to be promising tool for this purpose, not requiring any assumption on functions linking independent and dependent variables.Objective and hypotheses: The aim of the study was to compare ANN models of GH therapy effectiveness, based on the data available at therapy onset with multiple linear regression (MLR...

High incidence and male predominance of transient form of isolated growth hormone (GH) deficiency in children. What is the optimal time for GH therapy withdrawal and retesting?

Smyczyńska Joanna , Hilczer Maciej , Lewiński Andrzej , Smyczyńska Urszula , Stawerska Renata ,

Introduction: Normal growth hormone (GH) secretion after the attainment of final height (FH) is observed in the majority of GH-treated children with GH deficiency (GHD), however it is unclear when such normalization of GH secretion occurs.The Aim: Of the study was to assess the incidence of transient GHD in retesting with respect to pediatric criteria in the patients with isolated GHD diagnosed in childhood, depending on the moment of GH...

Effects of seasonal variability of insolation and COVID-19 pandemic isolation on vitamin D concentrations in children

Smyczyńska Joanna , Hilczer Maciej , Łupińska Anna , Pawelak Natalia , Lewiński Andrzej , Stawerska Renata

Introduction: Vitamin D may be considered as a hormone of prohormone of pleiotropic effects. Seasonal variability of insolation affects its synthesis in humans. In our latitude, vitamin D deficiency is widespread. In 2018, updated recommendations for vitamin D supplementation were published in Poland by Rusi&nacute;ska et al. In 2020, SARS-CoV-2 pandemic lockdown was introduced, with suggestions of protective anti-viral vitamin D role.<p class="ab...

Autoantibodies Against Some Selected Appetite-Regulating Peptide Hormones and Neuropeptides are Present in Serum of Short Children with Candida Albicans Colonisation and Helicobacter Pylori Infection

Stawerska Renata , Czkwianianc Elzbieta , Matusiak Agnieszka , Smyczynska Joanna , Prymus-Kasinska Sylwia , Hilczer Maciej , Chmiela Magdalena , Lewinski Andrzej

Background: Peptide hormones synthesized in gastrointestinal tract (GI) and adipose tissues, in addition to neuropeptides, regulate growth and body weight in children. The GI microflora (i.e. Candida albicans – CA and Helicobacter pylori – HP) is an antigenic source. Based on the molecular mimicry hypothesis, intestinal microbe-derived antigens may trigger the production of autoantibodies cross-reacting with regulatory peptides.<p class="abstext...

Serum Level of Osteoprotegerin and Total sRANKL in Adolescents with Type 1 Diabetes Mellitus

Szalecki Mieczyslaw , Wierzbicka Elzbieta , Pludowski Pawel , Jaworski Maciej

Background: There is still small clinical data regarding the influence of IDDM on bone structure, density and biochemical markers of bone turnover.Objective and hypotheses: To evaluate the potential role of OPG/sRANKL system in adolescents with IDDM and the influence of age, sex, metabolic control, diabetes duration and age of onset.Method: Serum concentration of OPG and total sRANKL in 60 children (25 boys and 33 girls) with IDDM ...

State of Knowledge of Late Endocrinological Effects of Hematological Patients Who Has Undergone Chemotherapy

Bien Beata , Budny Joanna , Kabaj Maciej , Gielzak Magda , Urbaniak Donata , Barg Ewa

Introduction: Medical advances result in cure and life extension. Modern methods of oncological treatment lead to late endocrinological side effects.Objective of the study: The aim of the study was to assess the patients’ knowledge of possible result of chemotherapy and its long-term effects linked to gonadal dysfunction.Materials and methods: The survey covered a group of 92 (62 women) patients with hematologic neoplasms at t...

Hypogonadotropic Hypogonadism in Patients with Congenital Adrenal Hypoplasia due to NR0B1 (DAX1) Mutations: Phenotype/Genotype Relationship

Niedziela Marek , Jamsheer Aleksander , Krawczynski Maciej R , Obara-Moszynska Monika , Rojek Aleksandra

Background: X-linked AHC is a rare disorder of the adrenal cortex caused by mutations in the NR0B1 (DAX1) gene. NR0B1 (DAX1) encodes for an orphan nuclear hormone receptor which is expressed in the adrenal, gonad, hypothalamus, and pituitary glands. Hypogonadotropic hypogonadism (HH) is the most frequently observed puberty disorder (absent or delayed puberty) caused by mutations in the NR0B1 (DAX1) gene and is due to impaired gonadotropin synthesis a...

A Severe LHRH-Independent Precocious Puberty in a 26-Month-Old Girl with a Clinical Diagnosis of McCune–Albright Syndrome

Flader Maciej , Latos-Bielenska Anna , Kapczuk Karina , Mankowski Przemyslaw , Malecka Elzbieta , Niedziela Marek

Background: Gonadal hyperfunction is the most frequent endocrine dysfunction in females with McCune–Albright syndrome (MAS), and precocious puberty (PP) is usually the first manifestation of MAS in children.Objective and hypotheses: The optimal pharmacologic treatment of PP in girls with MAS has not been yet identified and new therapeutic options like anti-estrogen should be taken under consideration especially in patients with extreme high estradio...

The relationship between the amount of ghrelin-positive cells in the stomach and the concentration of ghrelin and anti-ghrelin antibodies in the blood in short stature children, with additional analysis of the impact of H. pylori infection.

Kolasa-Kicińska Marzena , Stawerska Renata , Czkwianianc Elżbieta , Stawerski Wojciech , Stawerski Paweł , Foks Maciej , Lewiński Andrzej

Introduction: The growth process in children depends on GH/IGF-1. Ghrelin is stimulator of GH synthesis. Ghrelin also stimulates the orexigenic center peptides responsible for appetite. It is synthesized in the stomach, thus its secretion may be alter by gastrointestinal tract deseases. Recently, high titers of antibodies against some neuropeptides (including anti-ghrelin) have been found in indyviduals with certain microflora components, e.g. Helicobacter pyl...

Kolesinska Zofia , Acierno James Jr , Faisal Ahmed S. , Kapczuk Karina , Skorczyk-Werner Anna , Mikos Hanna , Rojek Aleksandra , Krawczynski Maciej , Pitteloud Nelly , Niedziela Marek

Background and objective: Given phenotype variability as well as limited utility of conventional endocrine investigations in reaching the diagnosis in a 46,XY patient suspected of a disorder of sex development (DSD), there is an increasingly stronger argument for considering targeted genetic sequencing at an earlier stage of the evaluation process. This study focused on identifying the relationship between clinical examination, endocrine and radiological assessment, as well as...
