Background: Weight disturbances in children are an important problem, both underweight and obesity having important health consequences. There is an ongoing debate about their cause, the risk factors involved and the need for public health policies focused on their prevention.Objective and hypotheses: The aim of this study was to estimate the prevalence of weight disturbances in a cohort of school-aged children and to analyse some factors considered to p...

Objectives: The etiopathogenetic of childhood obesity is related to genetic and environmental factors: not only caloric intake or physical activity have an important influence, but also circadian rhythms, including healthy sleep.The objectives of this study were: a) to analyze the different patterns and duration of sleep, eating habits, meal schedules, time dedicated to exercise and screens of obesity children; b) to evaluate its possibl...

Objective: KIMS (Pfizer International Metabolic Survey) was a postmarketing surveillance study of growth hormone (GH) replacement in adults and adolescents with GH deficiency (GHD) that concluded in October 2012. This analysis aimed to evaluate the overall safety outcomes from the full cohort of GH-treated patients of KIMS.Methods: Data were collected on adults and adolescents with confirmed GHD and closed epiphyses trea...

Introduction: As successful rates of haematopoietic stem cell transplantation (HSCT) are on the rise, late endocrine and metabolic effects of these survivors have become more prevalent.Aims: We aimed to characterise the endocrine abnormalities observed following HSCT.Subjects and methods: A retrospective descriptive study in paediatric post-HSCT patients (< 18 years-old) follow...

Background: Congenital hypothyroidism (CH) is a common and preventable cause of mental retardation in children, and is detected using dried blood spots in many neonatal screening programs. Upon suspicion of CH, plasma free thyroxine (FT4) and thyroid stimulating hormone (TSH) concentrations are measured. CH can be of thyroidal or central origin (CH-T and CH-C, respectively). While CH-T diagnosis is based on an elevated plasma TSH in combination with a low FT4,...

Background: P450 oxidoreductase (POR) mutations can present with disordered sexual development (46,XX virilisation as well as 46,XY under-masculinisation), perturbed steroidogenesis and mild to severe skeletal malformations. As POR is an obligate electron donating cofactor to many P450s, and as this interaction may vary from partner to partner, the phenotypic spectrum of PORD is extremely broad. Therefore, to characterize novel POR mutations, specific testing is required.<...

Background: Cytochrome P450 oxidoreductase (POR) deficiency (PORD) is a form of congenital adrenal hyperplasia (CAH) and results in steroid-production loss from cytochrome P450 proteins. Mutations in POR cause mild to severe forms of CAH with/without bone malformation symptoms resembling Antley-Bixler syndrome. We report a novel POR Arg550Trp mutation identified in a 46,XX patient with signs of aromatase (ARO) deficiency. Child (first pregnancy) and mother pr...

Background: Somavaratan, a novel long-acting rhGH fusion protein with t1/2>100 h, previously demonstrated clinically meaningful improvements in height velocity (HV) and IGF-I in prepubertal GHD children (Moore JCEM 2016).Objective and hypotheses: To evaluate maintenance of somavaratan treatment effects in the 2nd treatment year.Method: After subcutaneous pediatric doses were evaluated in a single dose PK/PD study (<e...

Background: Type 1 Diabetes (T1DM) is one of the most common paediatric endocrine disorders in India, but diagnosis is often delayed. Moreover, systematized data about symptoms, presentation, management and follow-up of T1DM in India is lacking. Absence of such data makes formulation of uniform region and nationwide protocols for diagnosis, management and follow-up of T1DM patients difficult.Objective and hypotheses: To generate data about presentation a...

Background: VRS-317, a novel fusion protein of rhGH, was safe and well tolerated in single dose studies of adults and children with growth harmone deficiency (GHD).Objectives: Conduct a 6-month study to determine the safety, tolerability, height velocity and IGF1 response in GHD children.Methods: 64 subjects were randomized into three arms to evaluate monthly, semi-monthly and weekly dosing.Results: At VRS-31...
