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 Gsα 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...

Comparison of Baseline Parameters and Response to GH Treatment in 125 Children with Short Stature with Eight Different Diagnosis

Ioimo Irene , Mussa Alessandro , Vannelli Silvia , Feyles Francesca , Einaudi Silvia , Matarazzo Patrizia

Background: Response to rhGH treatment is variable among GH deficiency (GHD), GH insensitivity and several intermediate conditions.Aims and objectives: To compare baseline parameters and response to rhGH treatment in eight diagnostic categories of patients with short stature.Methods: We selected 125 prepubertal children presenting at least 2 years of rhGH treatment (mean 5.29 years, range 2–15.6 years), hormonal and clinic par...

The Risk of Metabolic Syndrome among Dyslipidemic Children and Adolescents

Predieri Barbara , Colombini Giulia , Mazzoni Silvia , Bruzzi Patrizia , Lucaccioni Laura , Iughetti Lorenzo

Background: Lipid assessment is emerging as a useful and easy detectable tool to define the overall cardiovascular risk in children and adolescents. Nevertheless, no all dyslipidemic patients suffer the same cardiometabolic consequences.Objective and hypotheses: To compare anthropometric, biochemical and blood pressure variables among dyslipidemic children and adolescents according to the presence of metabolic syndrome (MetS).Metho...

Familial Short Stature Associated to Terminal Microdeletion of 15q26.3: Variable Phenotype not Involving the IGF1 Receptor Gene

Lucaccioni Laura , Madeo Simona F , Stanghellini Ilaria , Bruzzi Patrizia , Predieri Barbara , Iughetti Lorenzo , Percesepe Antonio

Background: Terminal deletions of chromosome 15q are associated with different degrees of pre- and post-natal growth failure, dysmorphic features, functional impairments and congenital anomalies. Although monosomies of 15q26 do not represent a classical contiguous gene syndrome, candidate genes for selected features have been identified. Short stature is referred to deletions of the IGF1-R gene, located on 15q26.3. We demonstrate evidence of phenotype comparable with 15q26 mon...

Predictors of Response to rhGH Treatment in 125 Children with Short Stature of Various Aetiologies

Ioimo Irene , Mussa Alessandro , Vannelli Silvia , Verna Francesca , Borraccino Alberto , Matarazzo Patrizia

Background: Response to rhGH treatment is extremely variable in pediatric growth disorders; predictors of the response are not yet clearly determined, due to disomogeneity of studied cohorts.Aims and objectives: To investigate the correlation between clinical parameters and height gain after the 1st year of rhGH treatment and at the last visit in eight different aetiologies of short stature, with the aim of identifying predictors of response to rhGH trea...

Off-label Use of Vaptans in Children with Severe Symptomatic Hyponatremia due to SIADH

Tuli Gerdi , Tessaris Daniele , Di Taranto Serena , Giorgis Alberto , Einaudi Silvia , Matarazzo Patrizia

Background: Vaptans, vasopressin receptor 2 antagonist, are used in adults to treat hyponatremia associated with congestive heart failure, cirrhosis, and the syndrome of inappropriate antidiuretic hormone (SIADH). To date, in paediatric patients with SIADH there are few data about use of vaptans, still considered off-label.Case presentation 1: A 9-yo female with surgically treated suprasellar astrocitoma developed chronic hyponatremia (121–128 mmol/...

Central Precocious Puberty in Cerebral Palsy

Bruzzi Patrizia , Messina Maria Francesca , Bartoli Alessandra , Lucaccioni Laura , Predieri Barbara , De Luca Filippo , Iughetti Lorenzo

Background: Children affected by cerebral palsy (CP) could experience central precocious puberty (CPP) 20 times more than general population. Nevertheless, the treatment is challenging.Objective and hypotheses: To compare CPP features and the effects of gonadotropin-releasing hormone agonist therapy (GnRHa) in children with CP and in controls.Method: The study involved 16 children with CPP and CP (median age (range) at diagnosis of...

Natural history of congenital hypothyroidism in the last two decades: what is changing? Experience of a single tertiary Italian paediatric centre.

Bruzzi Patrizia , Donini Valentina , Ciancia Silvia , Lucaccioni Laura , Predieri Barbara , Iughetti Lorenzo ,

Background and Aim: Congenital hypothyroidism (CH) is a well-known condition. Nevertheless, recent questions in clinical practice, especially in neonatal intensive care setting, prompted us to review the natural history of CH in our cohort.Methods: This is a retrospective, observational study collecting anamnestic, anthropometric (height SDS, BMI SDS), diagnostic (TSH, fT4, thyroid ultrasound) and therapeutic data (dose ...

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...

Incidental pituitary adenoma detection in two patients affected by Williams Syndrome: only a coincidence?

Ciancia Silvia , Madeo Simona F. , Cattini Umberto , Bruzzi Patrizia , Lucaccioni Laura , Predieri Barbara , Iughetti Lorenzo ,

Case reports: Patient 1 was diagnosed with Williams Syndrome (WS) when she was 11 years-old. She presented typical facial features, mental retardation (IQ 34) and chronic constipation. Pregnancy and neonatal period were unremarkable. Her growth has always been satisfying. No cardiac defects were detected at echocardiogram. Cerebral MRI showed enlarged pituitary (height of 9 mm) in the contest of which a mass with suprasellar extension was detected. Thyroid and adrenal...
