Background: Paediatric hypertension is increasing and has been associated with obesity and insulin resistance. Recently, cortisol:cortisone ratio and the metalloproteinase 9 (MMP9), which is a marker of vascular remodelling, have been syndicated as new risk factors associated with hypertension.Objective and hypotheses: To analyse the association between paediatric hypertension with clinical, biochemical, inflammation, and vascular remodelling biomarkers<...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED, OMIM240300) is a rare monogenic disease due to biallelic mutations in the Autoimmune Regulator (AIRE) gene. This encodes for a thymus-enriched transcription factor responsible for central immune tolerance. Classic diagnostic criteria are the presence of two of main symptoms of chronic mucocutaneous candidiasis (CMC), hypoparathyroidism (HP) and Addison’s disease (AD). Non-endocrine autoimmun...

Objective: Central precocious puberty (CPP) is a common condition in pediatric endocrinology practice. Gonadotropin-releasing hormone agonists (GnRHa) treatment is safe, but the real effect on final height and the ideal timing for treatment remains controversial. The purpose of the authors was to evaluate a nationwide representative group of CPP Portuguese girls treated with GnRHa, assess the effectiveness of treatment and the growth outcome before and after 8...

Silver-Russell syndrome (SRS) is a rare heterogeneous syndrome associated with severe prenatal and postnatal growth retardation.Context: There is little information on puberty onset and bone age trend in children with SRS.Study Design and partecipants: Retrospective observational study, including patients with a confirmed diagnosis of SRS divided in 2 molecular groups [ 11p15 loss of methylation, (...

Background: Autosomal dominant neurohypophyseal diabetes insipidus (adNDI) is characterized by arginine vasopressin (AVP) deficiency resulting from mutations in the AVP-NPII genePatients and Methods: We analyzed AVP-NPII gene in 13 kindreds with familial NDIAim: To describe the clinical and molecular features of Italian kindreds with adNDIResults</str...

Introduction: The dichotomous nature of the definition of Metabolic Syndrome (MS) in both children and adults can under-diagnose subjects at risk and prevents adequate follow-up of therapeutic interventions. Recently, a continuous score of MS (sSMp) was validated in the pediatric population based on the IDF criteria for a population> 16 years.Objectives: To apply sSMp in a Chilean pediatric population cohort and corr...

Background: Idiopathic central precocious puberty (CPP) is mostly described as an isolated entity. A few studies have shown its association with clinical syndromes and rare cases of chromosomal abnormalities.Objective: To clinically characterize patients with CPP, pointing out prevalent associated conditions and phenotypes.Patients and Methods: One hundred and forty-five patients with idiopathic CPP were retrospectively evaluated. ...

Background: A mutation in EIF2S3 (NM_001415; Xp22.11) was previously associated with microcephaly and developmental delay in a single pedigree. EIF2S3 encodes the eukaryotic translation initiation factor 2 subunit 3 (eIF2γ), the largest of three EIF2 subunits. EIF2 initiates protein synthesis by forming a ternary complex with GTP and initiator methionyl-tRNA which then binds to the 40S ribosomal subunit, enabling scanning of mRNA from the 5′ end to...

Background: Severe deficiency of 11β-hydroxysteroid dehydrogenase type 2 (11βHSD2) triggers activation of mineralocorticoid receptor (MR) by cortisol and causing apparent mineralocorticoid excess (AME) syndrome characterized mostly by low-renin arterial hypertension and hypokalemia. In 2003, we studied a patient with AME (3 years-old) having two homozygous mutation, D223N (rs121917833) and a SNP C>T in intron 3 (rs376023420) (Carvajal et al. JCEM 2003).<p cla...

Introduction: IPEX syndrome is a syndrome characterized by the following triad: immune dysregulation, polyendocrinopathy and X-linked enteropathy. It is produced by a variant in the FOXP3 gene. It is a rare disease with poor prognosis.Clinical case: We are reporting the case of a boy, 2nd child of non-consanguineous parents, normal pregnancy. Born at 39 weeks of gestational age, birth weight 2985 grams and length 49 cent...
