Apuzzo Diletta , Moracas Cristina , Izzo Anna , Di Mase Raffaella , Lorello Paola , Capalbo Donatella , Salerno Mariacarolina

Aims: The balance between hypo/hypercortisolism and hypo/hyperandrogenism is the main challenge in clinical management of patients with 21-hydroxylase deficiency (21OH-D). In adults, it has been established that both over and under-treatment might lead to the development cardiovascular risk factors. To date, only a few studies have addressed weather this risk begins in childhood. Aim of our study is to define the presence of early metabolic risk factors preval...

Determinants And Characteristics Of Insulin Dose Requirements In Children And Adolescent With New-Onset Type 1 Diabetes: Insights From The INSENODIAB Study

Beckers Maude , Lysy Philippe , Polle Olivier , Bernard Noémie , Gallo Paola

Aims: In children with new-onset type 1 diabetes mellitus (T1D), insulin dose regimens vary substantially. According to current ISPAD recommendations, the initial total daily dose (TDD) should range from 0.7 to 1.0 IU/kg BW/day. Adjusting TDD to achieve normal blood glucose concentration can take several days. The primary objectives of our INSENODIAB (INsulin SEnsitivity in New Onset type 1 DIABetes) study were to assess how patient characteristics influence i...

A 17-year-old girl comes to our attention for a second opinion due to reduced bone mineralization. She has a family history of osteogenesis imperfecta: her mother and younger sister have a COL1A1 mutation. The girl never had any fractures, but considering the familiarity it was carried out a DEXA, showing a Z-score of -1.9 SDS at the femoral level and -2 SDS at the lumbar level; no fractures visible in the spine X-ray. The genetic analysis of COL1A1 was carried out, which came...

Combined pituitary hormone deficiency caused by a missense de novo variant in FGFR1

Cavallaro Paola , Francesca Messina Maria , Aversa Tommaso , Pepe Giorgia , Wasniewska Malgorzata , Corica Domenico

Background: Heterozygous loss-of-function variants of fibroblast growth factor receptor 1 (FGFR1) are genetic causes of Combined Pituitary Hormone Deficiency (CPHD), Kallmann syndrome (KS) with anosmia/iposmia, Congenital Hypogonadotropic Hypogonadism (CHH) with normosmia and Septo-Optic Dysplasia. It is well-known that these variants are the main genetic factor underlying the development of CHH and KS; however, they have only occasionally been identified in C...

Auxological parameters and metabolic control in children and young patients with type 1 diabetes 1-year after COVID-19 pandemic.

Iughetti Lorenzo , Bruzzi Patrizia , Caccamo Paola , Di Caprio Antonella , Lucaccioni Laura , F. Madeo Simona , Trevisani Viola , Predieri Barbara

Introduction: COVID-19 pandemic, by restricting outside activities, encouraged a sedentary lifestyle due to social distancing and, alongside, an increase in the consumption of canned food and industrialized foods, resulting in a negative impact on the growth of children and young people (CYP). Concerns for consequences in CYP with type 1 diabetes (T1D) rose.Objectives: To investigate 1-year effects of the COVID-19 pandem...

Are we sure that the prevalence of SARS-CoV-2 infection is not underestimated? Usefulness of serological antibodies assays in children and adolescents with type 1 diabetes

Introduction: The true incidence of SARS-CoV-2 infection in children and young people (CYP) is unclear and data are influenced by testing strategies. CYP have so far accounted for 17.5-22% of diagnosed infections. In adults, diabetes was identified as risk factor for severe symptoms and hospitalization with the COVID-19. Eighteen months into the pandemic, studies in CYP with type 1 diabetes (T1D) reported only an increased prevalence of diabetic ketoacidosis (...

Association of the apoptotic markers Apo1/Fas and cCK-18 and the adhesion molecule ICAM-1 with Type 1 diabetes mellitus in children and adolescents.

Introduction: Type 1 diabetes mellitus (T1DM) is characterized by insulin-producing pancreatic β-cells loss. Apo1/Fas, a glycosylated surface protein, is implicated in maintaining homeostasis of the immune system. Cytokeratin-18 (cCK-18) is a predictive marker of liver disorders in T2DM. Intercellular adhesion molecule-1 (ICAM-1) is considered a candidate gene for susceptibility to diabetes mellitus. Aim: To investigate the possible role of Apo1/Fas, cCK-...

Short Stature and Single Central Incisor of The Upper Maxillar: Pathogenic Variant in The SHH Gene

Dominguez-Riscart Jesus , Arellano-Ruiz Paola , Garcia-Zarzuela Ana , Modamio-Høybjør Silvia , M Lechuga-Sancho Alfonso

Introduction: The Sonic Hedgehog (SHH) gene is involved in the development of midline structures. Pathogenic variantd in this gene have been associated to holoprosencenphaly 3; Microphthalmia with coloboma 5; Schizencephaly; and Single median maxillary central incisor syndrome (SMMCIS). All of them are inherited in an autosomal dominant pattern and exhibit incomplete penetrance as well as variable expressivity.Case Report:</stron...

A Rare HSD17B3 Gene Variant Presenting Virilization at Puberty: Management and Treatment in Adolescent Age.

Introduction: Pathogenetic mutations in the HSD17B3, located on chromosome 9q22, lead to 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) isoenzyme deficiency, etiopathogenetic for a disorder of sex development (DSD) with 46 XY karyotype and female phenotype at birth. 17β-HSD3 isoenzyme, expressed at testicular tissue, catalyzes the synthesis of testosterone from Δ4-androstenedione, allowing the correct development of male external genit...

Bone Homeostasis in Children with Subclinical Hypothyroidism: Effects of Two-years Treatment with Levothyoxine

Barbieri Flavia , Esposito Andrea , D'Acunzo Ida , Lorello Paola , Di Mase Raffaella , Improda Nicola , Capalbo Donatella

Background: Thyroid hormone plays a key role in bone mineral homeostasis and significant alterations in its circulating levels have been associated with an impairment in skeletal growth during childhood. To date, the effects of subclinical hypothyroidism (SH) on bones have not been studied and the management of this condition is still debated.Aim: To evaluate bone mineral density (BMD) in children with mild, persistent S...
