Background: Congenital isolated adrenocorticotrophic hormone (ACTH) deficiency (IAD) is a rare condition. It is characterized by low plasma and cortisol levels and preservation of all other pituitary hormones (2 cases described with transient partial growth hormone deficiency). The principal molecular cause is identified as TPIT mutation. We present here the case of a neonate with TPIT mutation and ACTH deficiency associated with probable growth hormone and thyrotropin deficie...

Background: Adrenocortical Tumors (ACT) is a rare endocrine malignancy with heterogeneous presentation.Aim: To evaluate the clinical, biochemical and pathologic characteristics of pediatric ACT in a single tertiary center.Subjects and methods: Review of 28 medical records with childhood ACT (chronological age (CA) <18 years (y) treated between 1987 and 2017. Clinical, biochemical, and histological features (Wieneke index), stag...

Background: FGF21 is a metabolic and growth regulator.Aim: To investigate the role of FGF21 during growth in infancy.Methods: Cohort of 40 term (T) and 40 preterm (PT) newborns whose length and weight were evaluated prospectively at birth, 6 months, and 12 months. Blood samples for FGF21, IGF1, leptin, insulin and glucose were collected at 6 and 12 months. In addition, FGF21, I GF-I, leptin, and insulin were measured in cord blood ...

Background and Objectives: Offspring born to obese mothers are at an increased risk of chronic disease including type 2 diabetes (T2D), obesity, hypertension, cardiovascular disease (CVD), non-alcoholic fatty liver disease (NAFLD) and chronic kidney disease (CKD). This metabolic programming is produced, in part, by epigenetic changes such us DNA methylation. We postulated that obesity exposure impacts the offspring's methylome and used an epigenomic approa...

Introduction: Congenital adrenal hyperplasia (CAH) is associated with long-term health problems. However, little is known about co-morbidities and their onset in children and young persons (CYP).Objective: To establish the health status of CYP with CAH across the United Kingdom.Methods: A multi-centre prospective study recruited 102 patients with 21-hydroxylase deficiency targeting...

Background/aims: The high complexity of Pediatric reference ranges across age, sex and units impairs clinical application and comparability of steroid hormone data, e.g., in CAHs. We developed a Multiples-of-Median (MoM) normalization tool to overcome this major drawback in Pediatric Endocrinology.Methods: LC–MS/MS data comprising 10 steroid hormones representing 905 controls (555 males, 350 females, 0 to >16 years) from two previous datasets we...

Background/Objective: Micro-and macrovascular changes are the cause for diabetes complications. Retinal vessel analysis is a unique method to examine microvascular changes in brain derived vessels.Subjects/Methods: Sixty-seven pediatric and adolescent type 1 diabetes patients and 58 healthy control persons underwent nonmydriatic retinal photography of both eyes. Arterioles and venules positioned in the region 0.5 to 1 diameter of the optic disc measured ...

Background/Aims: Since the introduction of Assisted Reproduction Technologies (ART), including classic In Vitro Fertilization (IVF) and Intacytoplasmic Sperm Injection (ICSI), in clinical practice, several studies have addressed concerns regarding the long-term health of the offspring, revealing indications of an adverse cardiometabolic outcome. Proprotein convertase subtilisin/kexin type 9 (PCSK9) circulating level is significantly associated with an increased risk of cardiov...

Background: Obesity in childhood and adolescence represents a major health problem of our century, and accounts for a significant increase in morbidity and mortality in adulthood. In Greece, more than 30–35% of children and adolescents are overweight or obese.Objective and hypotheses: To investigate the effectiveness of a comprehensive and personalized multidisciplinary management plan in reducing the prevalence of overweight and obesity in childhoo...

Background: In a large fraction of patients with clinically presumed Androgen Insensitivity Syndrome, no mutation of the Androgen Receptor gene can be detected. However, established Sanger sequencing techniques of the AR gene are often limited to the coding region.Objective and Hypotheses: To set up a next generation sequencing (NGS) approach of the entire AR locus (including UTRs, exons, introns, up- and downstream regions) for a comprehensive ...
