Introduction: Higher evening cortisol level has been previously described in very preterm infants, possibly reflecting increased Hypothalamic-Pituitary-Adrenal Axis (HPA) tone or alterations in HPA regulation throughout the day. These relatively subtle differences in HPA axis function in preterm compared to full-term children may become meaningful in terms of metabolic risk later in life if sustained over time. Still, only a few studies have investigated wheth...

Background and Aim: IRS1 (Insulin Receptor Substrate 1) is involved in the insulin signalling pathway and abnormalities thereof have been related to metabolic disorders and obesity. In obese subjects, insulin resistance has been associated with changes in IRS1 expression in peripheral in blood. Sex-based differences in cardiovascular disease are well established. Previous results from our group disclosed the association between IRS1 placental methylation with ...

Introduction: A global methylation array previously performed by our group in placental samples revealed a nominal association of a CpG site (CpGs) located at chr14:104552209 in the ASPG (Asparaginase) gene with childhood obesity. ASPG (Asparaginase) when used to treat haematologic neoplasms can cause liver steatosis. Asparaginase reduces asparagine blood levels, which is known to promote the development of metabolic syndrome and obesity in both child...

Introduction: Pituitary stalk interruption syndrome (PSIS) is a rare congenital disorder characterized by absent, thin, or interrupted pituitary stalk, absent or ectopic neurohypophysis, and hypoplasia or aplasia of the adenohypophysis. It often accompanies midline abnormalities and diverse endocrine dysfunction, with its etiology largely unknown. Recent reports have linked mutations in the ROBO1 gene to PSIS.Aim: To des...

Introduction: Congenital disorders of glycosylation (CDG) are metabolic conditions resulting from defects in the glycosylation pathway. In addition to the primary neurological symptoms, other possible clinical findings may include distinctive coagulation abnormalities, as well as hepatic, gastrointestinal and, less frequently, hormonal disorders. The ALG1 gene defect is the third most prevalent CDG and compromises β-1,4 mannosyltransferase activity, which...

Background: Individuals with androgen insensitivity syndrome (AIS) have an increased risk for developing a germ cell cancer (GCC). The risk is low during childhood; therefore, gonads are commonly preserved until after puberty. Little is known about GCC development in AIS during adulthood. This question is particularly relevant as many adult AIS women decline gonadectomy.Objective and hypotheses: To gain insight in attitudes towards gonadectomy in various...

Keywords: transgender, GnRH agonists, gender affirming hormones, final height, growth, pubertyBackground: Trans boys (TB) and trans girls (TG) who start medical gender-affirming treatment at Tanner stage 2-3 undergo early puberty suppression (ePS) with Gonadotropin-Releasing Hormone agonists (GnRHa) for several years and subsequently receive gender-affirming hormones (GAH), around 15-16 years. This treatment clearly inte...

Background: Steroidogenic Factor 1 (NR5A1/SF-1) is essential for the development and function of human sex and steroid organs. Variants of SF-1 lead to a broad spectrum of phenotypes including adrenal insufficiency and differences of sex development (DSD), but data on the whole picture of phenotypes in individuals with SF-1 variants are currently lacking. We aim to investigate the phenotype of individuals with SF-1 variants in a large interna...

Introduction: Neonatal Diabetes Mellitus (NDM) is characterised by severe hyperglycaemia, usually diagnosed in the first 6 months of life. Genetic diagnosis helps distinguishing between its different causes and between transient (TNDM) and permanent (PNDM) forms, with repercussions on the therapeutic approach and follow-up.Aim: Clinical and molecular characterisation of a series of NMD cases under endocrinological follow...

Objective: To synthesize evidence on subclinical hypothyroidism (SH) in children, focusing on prevalence, diagnostics, treatment, and progression.Methods: Review of 28 studies including observational cohorts and clinical trials on pediatric SH.Results: SH in children is associated with increased risks of obesity, metabolic syndrome, non-alcoholic fatty liver disease (NAFLD) due to ...
