Background: Pseudohypoaldosteronism (PHA) is a rare heterogeneous syndrome of mineralocorticoid resistance. PHA type 1 (PHA1) is characterized by neonatal salt loss, failure to thrive, dehydration and circulatory shock. It includes two forms: renal (autosomal dominant), due to mutations in mineralocorticoid receptor coding gene NR3C2, and systemic (autosomal recessive), due to mutations in subunit genes of the epithelial sodium channel (ENaC). ENaC is constituted of three subu...

Background: Vitamin D-induced hypercalcemia can result from exogenous vitamin D intoxication, excessive endogenous production or mutations in enzymes involved in vitamin D metabolism.Case Report: We describe an 8-month-old infant referred to the emergency department with history of failure to thrive and weight loss over the past two months. He was consuming type 2 formula milk supplemented with vitamin D plus vitamin D a...

Background: CDC (Centers for Disease Control and Prevention) reported an increased risk of newly diagnosed diabetes over 30 days after SARS-CoV-2 infection among persons aged < 18 years. Similarly, the results from the DPV Registry demonstrated a significant increase in the incidence of pediatric Type 1 Diabetes during COVID-19 pandemic. The underlying mechanisms are not yet elucidated.Aim: To investigate the incidenc...

Background: Type 1 diabetes (T1D) is a chronic disease characterized by autoimmune destruction of pancreatic beta-cells. Dysregulated miRNA levels have been described in T1D patients, though results are inconclusive.Objective and Hypotheses: The aim of this study was to assess the circulating profile of different miRNAs in children at diagnosis of T1D.Method: 27 children with T1D o...

Background: Young children affected by Type 1 Diabetes (T1D) are prone to glucose fluctuations and hardly reach a stable glycometabolic control, especially when treated with a Multiple Daily Insulin Injections (MDI) scheme. The recent Real-Time Continuous Glucose Monitoring (RT-CGM) System, Dexcom G5, the only available device registered for non-adjunctive insulin intervention, potentially facilitates a better management of the disease. Evidence regarding CGM effectiveness amo...

Background: The influence of intrauterine life on long term health is supported by a wealth of epidemiological and experimental studies. A low oxygen and/or nutrient supply to the fetus, resulting in intrauterine growth restriction (IUGR), may affect gonadal development of the offspring, with a potential impact on fertility. Data derived from animal models of placental insufficiency are very limited.Objective and hypotheses: To investigate the effects of...

Background: Prader–Willi syndrome (PWS) has a relative hypoinsulinemia and a lower insulin resistance than non-PWS subjects. Mostly on the basis of such higher insulin sensitivity, PWS subjects have been hypothesized to be at lower risk of non-alcoholic fatty liver disease (NAFLD).Objective and hypotheses: In this cross-sectional study, we analyzed the presence and the severity of NAFLD in a group of PWS children compared to matched pairs.<p cla...

Background: Low birth weight is associated with cardiometabolic risk in adulthood. To date, there is no evidence of a relationship between birth length and metabolic risk.Objective and hypotheses: To evaluate the relationship between birth size and risk of metabolic syndrome (MetS) in obese children.Method: 41 obese children were studied (23 females/18 males, 13.2±1.26 years). All patients underwent anthropometric, biochemical...

Background: Multiple autosomal recessive genes have been linked to primary adrenal insufficiency (PAI). Recently, sphingosine-1-phosphate lyase 1 (SGPL1) gene mutations were recognized as a cause of sphingolipidosis with multisystemic manifestations, including PAI. Sphingosine phosphate lyase (SGPL1) insufficiency syndrome (SPLIS) is characterized by steroid-resistant nephrotic syndrome, primary adrenal insufficiency (PAI), neurological deterioration, immunode...

Background: Next generation sequencing (NGS) has recently been proposed as a primary diagnostic tool in the work-up of children with idiopathic short stature (ISS) and born small for gestational age (SGA). The main limitation of a multi-gene approach is represented by the difficulty in the interpretation of VUS clinical significance.Aim: To identify and characterize genetic variants in a cohort of children born SGA and I...
