Background: Steroidogenic factor-1 (SF-1), denominated as nuclear receptor subfamily five group A member 1 (NR5A1), is an orphan receptor that regulates several steps of adrenal and gonadal development. Mutations in its gene are responsible for different phenotypes of disorders of sex development (DSD).Objective and hypotheses: To study the functional impact of two novel NR5A1 mutations, the p.C247* and p.K396Rfs*34, both identified within the l...

Background: Mannose binding lectin (MBL) is an important innate immune molecule and is previously found to be related to artery damage in some diseases as SLE rheumatoid arthritis and severe atherosclerosis. However, its role in artery change is still contradictory according to different studies. We found the carotid intima–media thickness (CIMT) increased in obese children which indicated an early change of atherosclerosis.Objective and hypotheses:...

Purpose: To examine the association of Insulin-like growth factor-1 (IGF-1) and binding protein-3 (IGFBP-3) with metabolic parameters of childhood obesity and assess its relationship with the presence of metabolic syndrome (MetS)Methods: A cross-sectional study of total 307 children and adolescents referred for growth assessment was performed. Subjects were divided into three groups based on body mass index (BMI) percent...

Background: Glucocorticoids play an important role in the developing fetus, the most important of which is lung maturation by increasing surfactant production and release. Glucocorticoid receptor (GR) functioning changes throughout the fetal period, especially during the transition to extrauterine life. Given the importance of glucocorticoids in lung development and functioning, studying glucocorticoid sensitivity in this population would be helpful, especially in the preterm ...

Background: Partial thyroxine-binding globulin deficiency (TBG-PD) is an endocrine defect with a prevalence of 1:4 000 in newborns. Due to the presence of a single TBG gene on the X chromosome.Objective and hypotheses: To investigate the clinical characteristics of twins with thyroxine binding globulin deficiency and to find SERPINA7 gene mutations.Method: Data related to clinical characteristics, serum biochemistry, gene mutations...

Background: Graft versus host disease (GVHD) is a complex disease resulting from donor T-cell recognition of a genetic disparate recipient, which is unable to reject donor cells after allogeneic transplant. Glucocorticoids (steroids) are the mainstay of acute GVHD therapy. Glucocorticoid resistance has been characterized in several inflammatory conditions including asthma, rheumatoid arthritis, systemic lupus, erythematosus, ulcerative colitis, and Crohn’s disease. Glucoc...

Introduction and Aim: FGF-23 is a hormone that works by inhibiting phosphorus reabsorption in kidneys, and systematic regulation of phosphate homeostasis by FGF23 depends on the activity of the membrane protein Klotho. It affects the active vitamin level according to the bioactive free vitamin hypothesis, which binds DVBP to vitamin D and prolongs its half-life. In this study, it was aimed to investigate 1.25 (OH) Vitamin D, Vitamin D Binding Protein, FGF-23 a...

Background: The adrenocorticotropic hormone (ACTH) is a 39 amino acid polypeptide secreted by the anterior pituitary and regulates cortisol secretion from the adrenal cortex. Cortisol has negative feedback and regulates the synthesis and secretion of the ACTH. Excess ACTH is associated with a wide range of diseases including congenital adrenal hyperplasia (CAH). Classic CAH due to the 21-hydroxylase (CYP21A2) deficiency causes a reduction or loss of cortisol synthesis. Here th...

Introduction: Diabetic ketoacidosis (DKA) is the most common cause of hospitalization, cerebral edema, and death among children with type 1 diabetes (T1D). Fatty acid-binding protein 4 (FABP4 or aP2) is one of the most abundant proteins in adipocytes and has been shown to be actively secreted from adipocytes. Circulating FABP4 is regulated by fasting- and lipolysis-related signals and contributes to hyperglycemia by promoting hepatic gluconeogenesis and interf...
