Background: Prediction of GH therapy effectiveness in children with short stature is an important issue in paediatric endocrinology.Objective and hypotheses: The aim of the study was to create a linear regression model of GH therapy effectiveness, based on the data available before treatment.Method: Retrospective analysis comprised the data of 150 short children (101 boys), diagnosed with isolated GH deficiency, who were treated wi...

Introduction: It is well known that low birth weight in children (born small for gestational age, SGA) predisposes them to the occurrence of obesity, insulin resistance (IR) and lipid disorders, observed even through the whole first decade of life. Thus, early diagnostics and prevention are very important. The HOMA index is used to assess insulin resistance (IRIHOMA). However, in some cases, high, prolonged postprandial insulin secretion is observed...

Introduction: Prolactin (Prl) - secreting cells and growth hormone (GH) - secreting cells are derived from the common somatomammotropic cells. Prl secretion depends primarily on the inhibitory effects of dopamine and the stimulatory effects of TRH and estrogens. The effects of other factors, especially the stimulation of the adrenergic system, are not well recognized. It is known that presynaptic stimulation of the alpha2-adrenergic receptor results in suppres...

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...

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...

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...

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...

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...

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...

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...
