Short-term impact of therapy with GNRH analogues on the growth of female children with central precocious puberty: a retrospective study of the last 20 years

Luísa de Carvalho Ana , Carvalho Adriana , Martins Sofia , Antunes Ana , Miguel Gomes Maria

Introduction: Since the 1980s, long-acting gonadotropin-releasing hormone analogues (GnRHa) have been the standard treatment for central precocious puberty (CPP).Aims: To evaluate the short-term response (at 6 and 12 months) of treatment with GnRHa in female children diagnosed with CPP, regarding growth, bone maturation (Greulich and Pyle method), predicted adult height (PAH) and pubertal development (Tanner stages)....

Pubertal induction in girls with hypogonadism: preliminary prospective data of efficacy in patients with/without initial overnight estrogen replacement

Rodari Giulia , Federici Silvia , Persani Luca , Arosio Maura , Bonomi Marco , Giavoli Claudia ,

Background: Pubertal induction in girls with hypogonadism through estrogen replacement therapy (ERT) aims at the development of secondary sexual characteristics, cognitive functions, uterine growth and maturation, bone mass accrual and linear growth. To date, the best induction regimen, capable of assuring both physiological gradual progression through Tanner stages and effective uterine development, is still to be established.Patients a...

Congenital hypogonadotropic hypogonadism and Cornelia de Lange Syndrome share clinical phenotype and genetic background

Kolesinska Zofia , Xu Cheng , Messina Andrea , Acierno James , Niederlander Nicolas , Santoni Federico , Papadakis Georgios , Pignatelli Duarte , Avbelj Stefanija Magdalena , Smith Kimberly Keefe , Balasubramanian Ravikumar , Crowley William , Pitteloud Nelly

Background: Congenital hypogonadotropic hypogonadism (CHH) is caused by impaired function of GnRH neurons, which clinically manifests by incomplete or absent puberty and infertility. The phenotype may be broader with other developmental anomalies such as anosmia, which is known as Kallmann syndrome. To date, there are more than 40 genes in which mutations underlie CHH. Cornelia de Lange Syndrome (CdLS) is characterized by facial dysmorphia, psychomotor delay, ...

From overt hyperthyroidism to normal thyroid function in TSH receptor activating mutations: reports of two families with novel pathogenetic variants and suggestion of a phenotypical sexual dimorphism

Citterio Valeria , Giavoli Claudia , Stellaria Grassi Elisa , Rurale Giuditta , Profka Eriselda , Rodari Giulia , Giacchetti Federico , Collini Valentina , Campi Irene , Arosio Maura , Persani Luca

Introduction: Familial non-autoimmune autosomal dominant hyperthyroidism (FNAH) is a rare cause of childhood hyperthyroidism caused by an activating variant of the thyroid stimulating hormone receptor (TSHR) gene. This disorder may occur as a result of an autosomal dominant inheritance or sporadically through de novo variation. The severity of hyperthyroid symptoms is variable and phenotype differences have been described in subjects harbouring the same mutati...

MicroRNAs Change and Target Key Regulatory Genes Involved in Longitudinal Growth in Patients with Idiopathic Isolated Growth Hormone Deficiency (IGHD) on Growth Hormone (GH) Treatment

Cirillo Francesca , Catellani Cecilia , Lazzeroni Pietro , Sartori Chiara , Ravegnini Gloria , Bonvicini Federico , Predieri Barbara , Amarri Sergio , Iughetti Lorenzo , Angelini Sabrina , Elisabeth Street Maria

The growth response in patients undergoing GH treatment is variable depending both on the patient's basal conditions and on personal innate sensitivity to therapy. MicroRNAs (miRNAs) are epigenetic regulators of gene expression, and are recognised as important regulators of biological and metabolic processes. It is unknown at present whether miRNAs could be early biomarkers of response to GH treatment in a perspective of individualised medicine, and whether they could disc...

Introduction: Craniopharyngiomas (CP) are rare pediatric intracranial tumors (1.2-4%) with a peak of incidence between 5-14 years . We retrospectively reviewed data of 16 cases (M/F 4/12) diagnosed before 4 years of age (median follow up 7.2 years) from a cohort of 117 patients (pts) (M/F 56/41) diagnosed after 01/01/2000, followed-up in 14 Italian centres of pediatric endocrinology belonging to the Italian Society for Pediatric Endocrinology and Diabetolo...

Response to Growth Hormone in Patients with Isolated Familial Growth Hormone Deficiency due to RNPC3 Mutations

Travieso-Suarez Lourdes , Martos-Moreno Gabriel , Pozo Jesus , Munoz-Calvo Maria , Chowen Julie , Frilander Mikko , Perez-Jurado Luis , Hawkins Federico , Argente Jesus

Background: We recently reported three children with severe isolated growth hormone (GH) deficiency and pituitary hypoplasia due to biallelic mutations in the RNPC3 gene, which codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. Although it is clear that these patients are GH deficient, the underlying mechanism for this deficit is not totally understood.Objective:...

Background: Monogenic diabetes is a heterogeneous group of metabolic disorders resulting from defects in single genes. Over 90% of the subjects remain undiagnosed, mainly because of lack of access to genetic testing.Objective and hypotheses: The aim of our study was to do a comprehensive genetic analysis of the whole pediatric and young adult autoimmune antibody negative diabetes population of Lithuania.Method: 860 children (age 0&...

Growth-Related Characteristics of Patients <18 Years of Age with Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency (21OHD): Real-World Evidence from the I-CAH Registry

Farrar Mallory , He Wei , Ali Salma R , Bryce Jillian , Lawrence Neil , Baronio Federico , Claahsen-van der Grinten Hedi L. , Bonfig Walter , Krone Nils , Yonan Chuck , Ahmed S. Faisal ,

Background: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare autosomal recessive condition characterized by cortisol deficiency and elevated ACTH secretion, resulting in excess androgen production. This exposure to excess androgens contributes to advanced skeletal maturation and reduced growth in puberty. Data from the I-CAH registry were analyzed to identify growth-related characteristics of children and adolescents with...
