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...

Protein arginine methyltransferase 7 (PRMT7), a member of a family of enzymes that catalyse the transfer of methyl groups from S-adenosyl-L-methionine to nitrogen atoms on arginine residues, is involved in multiple biological processes, such as signal transduction, mRNA splicing, transcriptional control, DNA repair, and protein translocation. Currently, 12 patients with homozygous/compound heterozygous mutations in PRMT7 gene have been described defining the ...

Objectives: 1. To describe the clinical, biochemical and testicular ultrasonographic features in a population of males with congenital adrenal hyperplasia (CAH) and Testicular Adrenal Rest Tumor (TART). 2. To identify factors related to the onset of TART. 3. To evaluate the therapeutic management and outcome of TART.Methods: Males with classic and non-classic 21β-hydroxylase-deficient CAH, diagnosed with TART, follo...

Background: Adrenal insufficiency (AI) is a rare condition caused by an inadequate production of glucocorticoids. Preliminary data in adults suggest that AI could be associated with an increased susceptibility to infections; moreover, AI patients are at risk to develop a severe course of infectious diseases and to experience a life-threatening adrenal crisis. The aim of our study is to evaluate the severity and the outcome of COVID-19 in pediatric AI patients ...

Background: Severe congenital growth hormone deficiency (cGHD) is a rare but potentially life-threatening condition. Even though random growth hormone (GH) can confirm cGHD during the first week of life, the diagnosis remains extremely challenging in the absence of reliable reference values in healthy neonates and thus of a best diagnostic cut-off.Aims: First, to provide solid reference values for GH concentrations in te...

Background: Reaching a definitive diagnosis in individuals with XY DSD is challenging and the time taken to reach a diagnosis is an important clinical benchmark that has not been sufficiently explored in this group of conditions.Objective: To evaluate the diagnostic process with a focus on the time to diagnosis in children with XY DSD reported via the e-reporting platform (e-REC) of the European Registries for Rare Endoc...

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by mutations in PHEX, leading to elevated FGF23 levels, hypophosphatemia and chronic renal phosphate wasting. Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for treatment of XLH. Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of study.Patients/Methods: ...

Diagnosis of craniopharyngiomas in childhood is often delayed due to nonspecific symptoms. In Italy all children are followed-up by paediatricians of the NHS and paediatric endocrinologists are present throughout the country. This would theoretically lead to an early diagnosis. We aimed to examine the clinical picture at diagnosis and duration of history before diagnosis in 117 patients (pts) followed-up at Endocrinology Centres belonging to the I.S.P.E.D..<p class="abstex...

Background: Primary adrenal insufficiency (PAI) is a rare life-threatening disorder. Data on PAI in children are scanty, with the exception of Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD).Objective and hypotheses: Evaluate etiology of PAI in a large cohort of children and characterize clinical presentation in subjects with PAI not due to 21-OHD.Method: Children followed in eight tertiary centers wer...

Adeno-associated virus (AAV) gene therapy reached the maturity and a liver-targeting approach is currently used as a replacement treatment for rare hepatic and muscular diseases. X-linked hypophosphatemia (XLH) is a rare disease associated with hyperfunction of fibroblast growth factor 23 (FGF23) in bone and characterized by severe skeletal deformities and short stature. The current medical therapies for XLH requires life-long repeated treatment presenting major limitatio...
