Background: Patients with autosomal dominant hypocalcemia type 1 (ADH1), due to germline gain-of-function calcium-sensing receptor (CASR) mutations, have hypocalcemia and seizures, hyperphosphatemia, hypercalciuria and inappropriately low parathyroid hormone (PTH) concentrations. Treatment for ADH1 comprises calcium and vitamin D analogs, however, their use predisposes to nephrocalcinosis and renal impairment. In contrast, recombinant human PTH(1-34) may incre...

Vosoritide is a C-type Natriuretic Peptide (CNP) analogue therapy for treatment of achondroplasia. Vosoritide acts on growth plate chondrocytes through the Natriuretic Peptide Receptor-B to stimulate increased endochondral bone growth, leading to increased growth velocity in treated subjects. In Phase II clinical studies, subject blood and urine samples were analyzed to monitor putative bone growth biomarkers including cross-linked C-terminal telopeptides of collagen II (CTxII...

Background: Data regarding epidemiology and management of Diabetic Ketoacidosis (DKA) in Italian children with T1D at disease onset are lacking.Method: From 1/1/2012 to 31/12/2013 a survey on DKA was conducted in all paediatric Centres belonging to the Italian Society for Pediatric Diabetology and Endocrinology. DKA was defined according to the ISPAD criteria. The following data were collected: treatment according ISPAD protocol yes or not, type of rehyd...

Background: Type 1 diabetes (T1D) is the most frequent etiology in Italian diabetic children and adolescents. Data on type 2 (T2D) and monogenic diabetes (MD) prevalence are scanty.Objective and hypotheses: To estimate the prevalence of T1D, T2D, secondary diabetes, and MD in a pediatric population of Italian diabetic patients.Method: Data on 3,076 patients (diabetes onset January 2007–December 2012, age at diagnosis <18 y...

Background and Methods: PCOS is common in adolescents and imparts a significant health and economic burden. Yet, our understanding of its complex pathogenesis is lacking. Proteomic analyses would be a valuable tool to deepen our knowledge of the biological pathways which underpin PCOS, and to identify novel biomarkers to diagnose and monitor this common condition. Therefore, we undertook a deep phenotyping discovery proteomic profiling (nano-2D-LC-QTOF MSe) on...

Introduction: Mutations in Insulin Receptor (INSR) is usually associated with insulin resistance and hyperglycemia. Homozygous or compound heterozygous mutations in INSR are usually linked with Rabson-Mendenhall or Donohue syndromes whilst heterozygous INSR mutations are associated with type A insulin resistance. Various autosomal dominant heterozygous INSR mutations leading to hyperinsulinemic hypoglycemia (HH) have been de...

Background: Polycystic ovarian syndrome (PCOS) is common, affecting up to one-fifth of females. PCOS is associated with significant comorbidity including metabolic dysfunction, pro-inflammation and mood disorders. Despite this, it is poorly understood, and diagnosis and management remain challenging in adolescents. Proteomics enables the better understanding of disease mechanisms and facilitates the identification of novel biomarkers.<st...

Aim: Glucose metabolism can affect by several genes, and some of them represent distictive clinical and laboratory features. tRNA methyltransferase 10 homologue A (TRMT10A) gene is a tRNA methyl transferase, and localised to the nucleolus, where tRNA modifications occur. Very recently, a novel syndrome of abnormal glucose homeostasis or nonautoimmune diabetes associated with microcephaly, epilepsy, intellectual disability, failure to thrive, delayed puberty caused by ...

Background: Polycystic ovarian syndrome (PCOS) is the most common hormone disorder in adolescent and young adult females, affecting 4–20% of the population. PCOS is associated with metabolic dysfunction, pro-inflammatory processes and mood disorders. Despite this, it is poorly understood in younger adolescents, and diagnosis and management remain challenging.Objectives: To better understand the clinical phenotype of PCOS in adolescents. Subsequently...

Background: Nutrition plays a pivotal role in long-term survival in cystic fibrosis (CF). Early insulin treatment for glucose intolerance promotes anabolism and stabilises lung function. However there is a variation in cystic fibrosis related diabetes (CFRD) screening across centres (recommended age for start of CFRD screening varies between 10 and 12 years as per CF trust, CFF & ISPAD guidelines).Aims: To assess if early screening of glycaemic statu...
