Background: Diabetic ketoacidosis (DKA), a frequent complication of type 1 diabetes (T1D), is characterized by hyperosmolar hypovolemia. The response of water-regulating hormones to DKA treatment in children is not well known. While arginine vasopressin (AVP) is thought to respond to changes in osmolality, aldosterone and atrial natriuretic peptide (ANP) are expected to respond to volume changes (dehydration and overhydration, respectively). The objective of t...

Introduction: The etiology of hyperandrogenism is diverse and diagnosis is based on history, clinical findings, reliable measurement of steroid hormones and genetic analyzes. In the electrochemiluminescence immunoassay (ECLIA) method, the presence of various endogenous compounds and the use of certain pharmaceutical agents may cause interference in results, on the other hand liquid chromatography-mass spectrometry (LC-MS/MS) method allows measurement of 17 adr...

Objective: This feasibility study aimed to investigate the anabolic effect of insulin on metabolites captured in exhaled breath during acute diabetic ketoacidosis (DKA) for a better pathophysiological understanding.Research Design and Methods: Children and adolescents with type 1 diabetes (T1D) with DKA (n=5) and without DKA (n=7) and children with epilepsy without ketogenic diet (n=18) were re...

Background: The phenotypic spectrum of short stature homeobox-containing gene deficiency disorders (SHOX-D) ranges from non-specific short stature to Leri-Weill dyschondrosteosis. Current guidelines support rhGH in SHOX-D children, but long-term data are still lacking. Moreover, no correlation has been established yet between the severity of phenotype, including the response to rhGH, and the underlying SHOX pathogenic variant.Aims: To ev...

Nicotinamide nucleotide transhydrogenase (NNT) is expressed in the heart, thyroid, and testicles, where it maintains the balance of reactive oxygen species in the mitochondria. It is linked, by an insufficiently described mechanism, to primary adrenal insufficiency (PAI) with or without mineralocorticoid insufficiency and several extra-adrenal manifestations (i.e. gonadal adrenal rest tumors, cardiomyopathy, hypothyroidism, and precocious puberty). A comprehensive and chronolo...

Background and Aim: Several genetic variants associating with hepatic fat content in adults have been identified in genome-wide association studies. Their effects in children remain unclear. This study aimed to test the effect of genetic variants known to associate with hepatic fat in adults, individually and combined as a genetic risk score (GRS), on cardiometabolic traits, and to investigate the predictive ability of the GRS for hepatic steatosis in children...

Introduction: Central precocious puberty (CPP) is due to premature activation of the hypothalamic-pituitary-gonadal axis. Mutations in the imprinted gene MKRN3 are the most common monogenic form of CPP. Recently, attention was directed to DLK1, another imprinted gene. Defects in this gene resulted to be a rare cause of CPP in girls and adult women with precocious menarche, obesity and metabolic derangement. We aimed to investigate a cohort of female and male p...

Objectives: To evaluate the potential diagnostic role and sensitivity of T2-weighted DRIVE sequence in pituitary stalk (PS) identification and measurements in patients with hypothalamic-pituitary disorders. The degree of agreement and reliability between standard pre- and post-contrast T1-weighted images and T2-DRIVE will be tested in a large group of patients with pituitary dysfunction.Design: We searched for pituitary MRI reports using ‘T2-DRIVE&#...

Background: Homozygous natriuretic peptide receptor-2 (NPR2) mutations cause acromesomelic dysplasia, type Maroteaux, a skeletal dysplasia with extreme disproportionate short stature and recently, heterozygous NPR2 mutations have been identified also in patients with idiopathic short stature (ISS, 2–6%). SHOX mutations are found in ~2–5% of ISS cases and ~70% of Léri-Weill dyschondrosteosis (LWD) cases, characterized by disproportionat...

Background: The hepatokine FGF21 signals through a dual receptor complex consisting of FGFR1c and the obligatory co-receptor β-Klotho to regulate glucose and lipid metabolism. Interestingly, female mice with Fgf21 transgenic overexpression are not only resistant to high-fat diet induced obesity but also present with hypogonadotropic hypogonadism (HH) and infertility. Loss-of-function (LOF) mutations in FGFR1 are a frequent cause of congenital HH (CHH). W...
