Long-term Teriparatide (rhPTH) Treatment in Children with Syndromic Hypoparathyroidism

Buganza Raffaele , Tuli Gerdi , Matarazzo Patrizia , Tessaris Daniele , De Sanctis Luisa

Background: Hypoparathyroidism is characterized by absence or inadequately low circulating concentrations of parathyroid hormone, resulting in hypocalcaemia, hyperphosphataemia and elevated fractional excretion of calcium in the urine. The use of activated vitamin D analogues and calcium supplements are recommended as the primary therapy. To avoid vitamin D and calcium side effects, subcutaneous recombinant human parathormone [rhPTH (1-34)] has been proposed f...

Plasma Copeptin Distribution in the Pediatric Age: A Useful Diagnostic Tool for AVP-Related Disorders

Tuli Gerdi , Tessaris Daniele , Buganza Raffaele , Matarazzo Patrizia , De Sanctis Luisa

Introduction: Copeptin is a stable AVP surrogate, secreted in equimolar relationship, who has been proposed for the diagnosis of AVP-related hypo and hypernatremic disorders, i.e. the syndrome of inappropriate ADH secretions (SIADH), the cerebral/renal salt wasting syndrome (C/RSW) and diabetes insipidus (DI). Few data exist about the normal ranges for plasma copeptin levels in the pediatric age, reported between 2.4-8.6 pmol/L. The aim of this study is to rep...

Autoimmune Polyendocrine Sydrome Type I: A Neuroendocrine Multi-Systemic Disease with a Variable Expressivity

Carpino Andrea , Pinon Michele , Montin Davide , Tuli Gerdi , de Sanctis Luisa , Matarazzo Patrizia

Introduction: Autoimmune polyendocrine syndrome type I (APS-1) also called autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare monogenic autosomal recessive disease known by the triad of the major components hypoparathyroidism, primary adrenocortical insufficiency and chronic mucocutaneous candidosis. However, many minor diseases could be present such as other endocrine manifestations (gonadal insufficiency, DM type 1, thyroid dis...

ENPP1 Hypophosphatemic Rickets in a 3.6 Years Old Italian Child

Tessaris Daniele , Abrigo Enrica , Tuli Gerdi , Matarazzo Patrizia , de Sanctis Luisa

Introduction: Although vitamin D deficit is the most common cause of rickets there are many rare genetically transmitted forms as hypophosphatemic rickets, a family of hereditary diseases characterized by low phosphorous plasma levels and resistance to 25OH-vitamin D replacement.Case report: This is the case of a 3.6 year-old Italian child sent from the General Pediatrician, for rickets suspicion. Silent personal history...

Combining COLD and MAMA-PCR Real Time Taqman Tecniques to Detect and Quantify the R201 GNAS Mutation Causing McCune-Albright Syndrome

de Sanctis Luisa , Bergallo Massimiliano , Galliano Ilaria , Montanari Paola , Tessaris Daniele , Matarazzo Patrizia

Background: McCune-Albright syndrome (MAS; OMIM#174800) is a rare disorder hallmarked by the triad fibrous osseous dysplasia, cafè-au-lait skin spots and endocrine hyperfunctions, usually peripheral precocious puberty. It is caused by post-zygotic activating mutations at R201 codon of the GNAS gene, which lead to a somatic mosaic state; the clinical manifestations of MAS are highly heterogeneous due to variability of mutation abundance among affected tissues.<p class=...

Genetic and Epigenetic Alterations at the GNAS Locus and Clinical Consequences in Pseudohypoparathyroidism: A New Healthcare Pathway

Giachero Federica , Elli Francesca M , Baricco Marta , Matarazzo Patrizia , Mantovani Giovanna , de Sanctis Luisa

Background: Genetic and epigenetic alterations at the GNAS locus are responsible for the GsĪ± protein dysfunctions causing Pseudohypoparathyroidism (PHP), a heterogeneous disease characterized by multiple hormone resistances and AHO signs (short stature, obesity, round face, brachydactyly, subcutaneous ossifications and mental retardation). A clinical overlap among molecular subtypes of the disease (Ia, Ib, Ic and II) makes the current classification inadequate; furthermor...

"Lympocyte population in children and adolescents affected by Graves’ disease. Potential predictive tool of disease severity"

Tuli Gerdi , Munarin Jessica , Tessaris Daniele , Matarazzo Patrizia , De Sanctis Luisa ,

Introduction: Graves-Basedow disease (GD) is the most common cause of thyrotoxicosis in pediatric age. Multi-factorial pathogenesis stand on the basis of the autoimmune disorder activation, leading to lymphocyte imbalance that include increased CD4+ and CD8+ subtypes, increased CD4+/CD8+ ratio and B cells dysregulation. The aim of this study is to determine the potential prognostic value of lymphocyte population parameters in pediatric GD.<p class="abstext...

Peripheral Precocious Puberty in girls affected by McCune-Albright Syndrome: safety and efficacy retrospective study on letrozole treatment

Tessaris Daniele , Gazzin Andrea , Bonino Elisa , Tuli Gerdi , Matarazzo Patrizia , de Sanctis Luisa ,

Introduction: Precocious Peripheral Puberty (PPP) due to autonomous ovarian activation is the most frequent endocrinopathy in girls with McCune-Albright Syndrome (MAS). Main goals of treatment for PPP are to reduce signs of estrogen exposure, also improving final height, and mitigate secondary psychological influence of sexual hormones exposure. This retrospective study analyzes the long-term safety and efficacy of letrozole treatment in a cohort of girls with...

Clinical-molecular assistance pathway for primary bone fragility: a pediatric monocentric experience

Tessaris Daniele , Gavello Federica , Bonino Elisa , Tuli Gerdi , Matarazzo Patrizia , Deaglio Silvia , de Sanctis Luisa

Bone fragility is a more typical condition of old age, linked to physiological aging. In pediatric age, on the contrary, it represents a rare problem, but more often has an underlying primary cause. This condition manifests itself in most cases with recurrent or abnormal fractures and bone deformities, with a limitation of mobility, bone pain and consequent reduction in the quality of life of the child. The great difficulty for the clinician consists in reaching a correct diag...

Case Report: the rare case of pediatric myxedema due to an unrecognized chronic autoimmune hypothyroidism

Bonino Elisa , Matarazzo Patrizia , Buganza Raffaele , Tuli Gerdi , Munarin Jessica , Bondone Claudia , de Sanctis Luisa

Hypothyroidism is the most common thyroid disorder in children. It usually presents with nonspecific symptoms, that can be mild and occur slowly over time, compromising a timely diagnosis, with possible effects on pituitary gland, multiple organs and growth. In case of long-standing unrecognized hypothyroidism, myxedema or myxedema coma can occur, rare but severe conditions. This case report describes an adolescent presenting with extensive trunk and neck swelling. After exclu...
