Introduction: Prader-Willi syndrome (PWS) is a rare congenital neurodevelopmental disorder characterized by hyperphagia, growth hormone (GH) deficiency, short stature, and low bone mineral density. The mechanisms concerning bone metabolism disturbances in these patients are still unclear. An important role in the process of bone formation is played by osteocalcin (OC), the most abundant non-collagen protein of the bone matrix. OC has three potential gamma-carb...

Introduction: Obesity is the direct cause of a number of immediate problems during childhood. Recently, fat mass was described as a significant negative predictor of serum iron. Hepcidin is a hormone stimulated by an increase in plasma iron levels and iron deposits in tissues, and decreases iron release from macrophages and duodenal enterocytes into the plasma. This protein prevents excessive iron absorption and iron accumulation in tissues. Ferritin is the most commonly deplo...

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...

Background: Children at type 1 diabetes (T1DM) diagnosis can develop ketoacidosis (DKA), a life-threatening condition, which is most frequently associated with the onset of diabetes in children aged <5 years.Aims and objectives: We studied the prevalence of DKA at T1DM diagnosis and the frequency of partial remission (PR) in children from Wielkopolska province, Poland.Method: The cohort comprised 735 children aged 0–18 yea...

Thyroid Function and Autoimmunity in Children with Newly Diagnosed Type 1 Diabetes Mellitus

Niechcial Elzbieta , Skowronska Bogda , Gertig-Kolasa Anna , Krzysko Izabela , Stankiewicz Witold , Michalak Michal , Fichna Piotr

Background: Patients with type 1 diabetes (T1DM) are at a high risk of having other autoimmunological diseases. The most common coexisting disease is autoimmune thyroiditis, which is diagnosed in 15–30% diabetic patients. The incidence of the disease depends on the age, sex, and duration of T1DM.Aims and objectives: This study aims to assess the prevalence of anti-thyroid peroxidase antibodies and anti-thyroglobulin antibodies in children with newly...
