Background: Optimising adherence to treatment in paediatric patients is important, since non-adherence may lead to incorrect interpretation of growth results and in the treatment course. It has been found that injection frequency is correlated with growth response and final height among children treated with rhGH.Objective and hypotheses: The main aim of this study was to evaluate IGF1 levels and growth velocity before and after a medical intervention in...

Background: Mexico is globally ranked as one of the countries with the highest incidence of congenital hypothyroidism. There are few studies that have searched for germinal mutations of candidate genes, such as NKX2-1, in patients with congenital hypothyroidism.Objective and hypotheses: i) To search for NKX2-1 mutations in blood samples of patients with confirmatory diagnosis of congenital hypothyroidism (CH) due to thyroid dysgenesis (...

Introduction: Central precocious puberty (PPC) is defined by the appearance of sexual characters at a chronological age lower than -2.5DS of the average for the reference population. Diagnostic is clinical but the hormonal assessment is essential. Basal gonadotropin values are not enough for the diagnosis. Gonadotropin-releasing hormone (GnRH) stimulation tests evidence the activation of the hypothalamic-pituitary-gonadal axis, however there is controversy abo...

Background: The GnRH-agonists are the drugs of choice for therapy of idiopathic-CPP. To assess two different GnRH-agonist (Leuprolide acetate: LA vs Triptorelin depot: TD) treatment effects on anthropometric measurements.Patients and methods: 74 girls with ICPP (mean age 33.8±8 years) were enrolled the study. Complaints had been begun before 8 years old. 50 girls underwent GnRH stimulation test. 58 girls with ICPP were followed up 18 months. Childre...

Background: IGF1 resistance syndrome (IGF1RS) is characterized by intrauterine and postnatal growth deficit with normal or supranormal IGF1 levels. Additional features may include intellectual deficit, microcephaly and dysmorphisms. IGF1RS may be caused by genomic or genetic defects affecting the IGF1R locus (15q26.3).Objective and hypotheses: To investigate the frequency of IGF1R mutations in a cohort of patients with pre- and/or postn...

Pseudohypoparathyroidism (PHP) and related disorders lead to a wide spectrum of abnormal physical characteristics, neurocognitive and endocrine abnormalities. PHP (including all subtypes), pseudoPHP, acrodysostosis and progressive osseous heteroplasia refer to heterogeneous disorders characterized by physical findings, differently associated in each subtype, including short bones, short stature, stocky build, subcutaneous ectopic ossifications, as well as laboratory abnormalit...

Introduction: Formulations and doses of GnRH analogues used to treat idiopathic central precocious puberty (iCPP) may vary with clinician preference or local approvals. Aim of this study is to define factors that affect initial depot leuprolide acetate (LA) dose which suppress hypothalamo-pituitary-gonad (HPG) axis in girls with iCPP.Methods: A total of 220 girls receiving LA for iCPP were included. LA is started in the dose of 3.75 mg/28 days, and suppr...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Introduction: Data on BP in children with classic congenital adrenal hyperplasia (CAH) is inconsistent.Aim: To assess the trend in BP throughout childhood using data from the International CAH registry and compare this to normative data from the American Academy of Paediatrics (AAP).Method: This retrospective multi-centre study included 37 centres from 20 countries. BP data was ana...

Background: The patatin like phospholipase containing domain 3 (PNPLA3) I148M polymorphism has an effect on modulation of estimated glomerular filtration rate (eGFR) in non-obese non-diabetic adults and in children with histologically confirmed Non-Alcoholic Fatty Liver Disease (NAFLD).Objectives: To explored the impact of PNPLA3 I148M polymorphism on eGFR in obese children with and without NAFLD.<p class="a...
