Introduction: Sulfation is required for the metabolism of numerous compounds, including proteoglycans, steroid hormones, neurotransmitters, toxic chemicals, and drugs like acetaminophen. The sulfate transporter SLC13A1 is responsible for the intestinal absorption and the renal reabsorption of inorganic sulfate, but loss-of-function mutations in this gene have never been described in man. Here, we describe a male with a biallelic loss-of-function variant, i.e.,...

Objective: This project aims to evaluate the effect of two isotopically labelled internal standards on the quantification of 17OHP by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) as an orthogonal technique.Methods: Three LC-MS/MS and one GC-MS/MS laboratories, spanning four countries worldwide, who routinely measure serum17OHP, compared two internal ...

Context: The unified approach for obese children can result in therapeutic failure as obesity is a symptom of several conditions. It was previously suggested that only children with obesity onset beyond age 6 years will develop the metabolic syndrome and T2D. In turn, early childhood obesity carries a few times less risk of adult obesity comparing to that with the onset during juvenility.Aim: We determine the clinical an...

Context: The traditional approach to childhood obesity management is lifestyle modification/LSM. Nevertheless, the response rate is variable and difficult to predict.Aim: A systematic search for markers to predict outcomes of simple LSM in pediatric obesity management.Patients/Methods: Out of 240 children with obesity (BMI>97%), recruited to a prospective ‘multi-OMICS’ study granted b...

21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in the CYP21A2 gene. 21OHD causes a wide array of clinical symptoms that result from gluco- and mineralocorticoid deficiency and adrenal androgen excess. In most cases, supra-physiological glucocorticoid doses are necessary which may cause short stature, obesity, hypertension, cardiovascular and metabolic co-morbidity with reduced quality of lif...

Background: Type 1 diabetes mellitus (T1DM) is one of the most frequent chronic diseases in the pediatric age and demands constant and rigorous glycemic control. Intermittently scanned continuous glucose monitoring (isCGM) systems are a helpful tool in diabetes management. Second-generation isCGM contain alarms to assist in the detection of hyper or hypoglycemia. We aimed to compare the sleep quality of principal caregivers of T1DM pediatric patients who use i...

Introduction: Bardet-Biedl syndrome is a rare autosomal recessive disease, characterized by rod-cone dystrophy, truncal obesity, left foot polydactyly, cognitive impairment, male hypogonadotrophic hypogonadism, female genitourinary malformations, and renal abnormalities. The authors present 3 cases of Bardet-Biedl syndrome diagnosed during pediatric age.Case description: Case1: A 3-year-old girl with a f...

Introduction: Angiopoietins are necessary for development, differentiation and stabilization vessels progress. Angiopoient 1 (Ang-1) is responsible for vascular integrity, through stimulation of endothelial cell migration and adhesion, and inhibition of apoptosis. Action of angiopoietin 2 (Ang-2), in the absence of VEGF it Leeds to vascular regression, but in the presence of high VEGF concentration it stimulates angiogenesis. Stromal derived factor (SDF-1) play an important ro...

Introduction: Vitamin D (VitD) is a prohormone that is synthesized in the skin after sun exposure. Mandatory lockdown during the COVID-19 Pandemic may have altered the sun exposure time of children.Aim: to evaluate vitD levels in a sample of children and adolescents, and compare between pre-pandemic and pandemic periods.Methoths Children and adolescents, from a Portuguese tertiary ...
