Liquid chromatography associated with tandem mass spectrometry (LC-MS/MS) is currently considered the gold standard for steroid measurement. The aim of this study was to compare traditional immunoassay and LC-MS/MS methods for androgens measurement before and after human recombinant chorionic gonadotrophin (hrCG) stimulation in children with diagnosis of disorder of sex development (DSD) with 46,XY karyotype and past of normal testosterone secretion. We evaluated 19 patients, ...

NPR2 Gene Mutations Associated with Acromesomelic Dysplasia Maroteaux Type are Mostly Unique to Families

Castro-Feijoo Lidia , Barreiro Jesus , Guillen-Navarro Encarna , Journel Hubert , Wakeling Emma , Jagadeesh Sujatha , LeMerrer Martine , Silva Paula , Cabanas Paloma , Pombo Manuel , Loidi Lourdes

Background: Acromesomelic dysplasia Maroteaux type (AMDM) (OMIM 602875) is a rare autosomal recessive skeletal disorder with an approximate prevalence of 1/1,000,000) and characterized by severe dwarfism accompanied by shortness of distal and middle segments of extremities. Mutations in the NPR2 gene which encodes for the natriuretic peptide receptor B (NPR-B) is the underlying genetic cause of this disorder.Objective and hypotheses: Genetic con...

Large-Born Infants Switch from an Adipose to a Lean and Insulin-Sensitive State with Low Concentrations of Circulating Myostatin and Follistatin

Sebastiani Giorgia , Cruz Miriam Perez , Silva Marta Diaz , Roig Maria Dolores Gomez , Bermejo Abel Lopez , Toda Lourdes Ibanez , De Zegher Francis

Background: Muscle is key to glucose metabolism. Myogenesis is completed in early infancy, partly under the inhibitory control of myostatin, a myokine whose actions can be influenced by follistatin. Early lowering of myostatin actions is thus a potential strategy to reduce the risk for later diabetes.Objective and hypotheses: We performed a first screening of whether such lowering is among the natural mechanisms whereby some human infants augment their l...

Identification of a novel homozygous mutation in LEPR gene associated with severe early-onset pediatric obesity in two sisters from Central Brazil

Machado Pinto Renata , P Pinto Irene , G Rodovalho Ricardo , de O Silva Lorena , VC Fukushima Lorraine , S Moreira Vanessa , S B de Souza Cristiane

Introduction: Early-onset severe obesity (before five years of age) without intellectual deficit, dysmorphisms, or malformations raises the hypothesis of monogenic obesity. The leptin receptor (Lepr) pathway is essential for food intake regulation, energy expenditure, and body weight. Mutations in leptin and the Lepr have been shown to cause early-onset severe obesity in mice and humans.Objective: To report the clinical ...

Incidence study of central precocious puberty in the population of goiás-brazil: the covid-19 pandemic has changed epidemiology.

Machado Pinto Renata , Luz Castelo Branco De Souza Gabriela , Moraes Magalhães Gustavo , Gelinski Isabely , Felipe Macedo Silva Luiz , Pereira Pinto Roney

Introduction: An increase in the number of cases of central precocious puberty (CPP) was observed in outpatient clinics in various centers around the world during the COVID-19 pandemic. It is believed that the adoption of specific social behaviors, and the virus infection itself may have influenced the increase in cases of CPP.Objective: To analyze the epidemiology and clinical characteristics of cases of CPP in the stat...

Background: Most published studies on 46,XY DSD focused on genetic findings without association with biochemical work-up.Objectives: To retrospectively analyze the clinical and genetic findings of a large cohort of 46,XY DSD patients.Methods: 285 non-syndromic 46,XY DSD individuals (192 sporadic and 89 familial cases) were studied. LH, FSH, testosterone (T), androstenedione (A) wer...

Gender variability and associations of blood dopamine, leptin and insulin in overweight children.

Viazava Liudmila , Solntsava Anzhalika

Background: Some neuropeptides and hormones, for instance dopamine, leptin and insulin can affect the food consumption, eating behavior and can lead to obesity. Research goal was to discover the gender differences, associations and joint influence on body weight of blood dopamine (DA), leptin (LP) and insulin (Ins) concentrations in obese children.Material and methods: We discovered cross-sectional retrospective data of ...

Analysis of Steroid 5-Alpha Reductase 2 (SRD5A2) Gene in Patients with 46,XY Disorder of Sex Development

de Souza Giselle Neres , Machado Aline Zamboni , Prado Arnhold Ivo Jorge , Mendonca Berenice , Palma Sircili Maria Helena , Nishi Mirian Yumie , Barbosa Silva Rosana , Frade Costa Elaine Maria , Domenice Sorahia

Background: The diagnosis of 46,XY disorder of sex development (DSD) due to 5-alpha reductase 2 (5α-RD2) deficiency has been based on testosterone:dihydrotestosterone (T:DHT) ratio, urinary steroid profiling and mutational analysis of SRD5A2 gene. The biochemical hallmarks of 5α-RD2 deficiency include increased T:DHT ratio. However, several difficulties are observed in the DHT measurement leading to misdiagnosis. The mutational analysis of the SRD5A2 has been propose...

Childhood obesity is associated with present and future complications, including type 2 diabetes and cardiovascular disease. Although lifestyle interventions (i.e. dietary and physical activity counselling) are the cornerstone of therapy, their impact on body mass index (BMI) is limited. The phase 3a SCALE Kids study (NCT04775082) demonstrated superiority of liraglutide 3.0 mg versus placebo, plus lifestyle interventions, for BMI reduction in children with general (i.e. non-mo...
