Background: The ECOS observational study in Spain (NCT01376921) aims to evaluate adherence to r-hGH therapy prescribed via the easypod™ electromechanical auto-injector device and to analyse factors that may influence adherence in paediatric patients. Easypod™ administers pre-set doses of Saizen® r-hGH and stores accurate records of each dose and injection taken, which can then be shared with the HCP for evaluation of the patient’s adherence.<...

Background: AuxoLog is a validated computer program that evaluates auxologic parameters comparing them with the Spanish growth charts. It also allocates subjects to the corresponding pubertal development group.Objective: To assess the evolution of auxological parameters in GH deficient (GHD) pre pubertal children treated with Omnitrope for a minimum of 2 years prior to puberty.Method: This study is non-interventional, retrospective...

Background: Increased uric acid is an independent risk factor for cardiovascular disease in obese adults and adolescents. The relationship between uric acid and atherosclerotic risk early in life is unknown.Objective and hypotheses: We investigated whether uric acid relates to carotid intima–media thickness (cIMT), a marker of preclinical atherosclerosis, in a rather large sample of school-age children and investigated the interaction of obesity sta...

Background: In rodents, fibroblast growth factor 21 (FGF21), an endocrine member of the FGF family, is mainly produced in the liver and promotes glucose oxidation in several tissues; the circulating concentrations of FGF21 rise shortly after birth. In the human, the ontogeny of circulating FGF21 is essentially unknown.Objective and hypotheses: To assess whether there is also a neonatal surge of circulating FGF21 concen...

Background: The Spanish Registry PUBERE was created (2007) with 53 hospitals.Objective and hypotheses: i) To determine the chronological age (CA) and bone (BA) at GnRH analogue withdrawal; ii) to analyze the age at menarche and time elapsed after stopping treatment; and iii) to know adult height data.Method: Patients with central precocious puberty (CPP) born after 1992, diagnosed before 8 years in girls, with BA/CA >1 year and...

Background: The interrelationships between body weight and thyroid status are complex. Serum TSH is typically increased in obese compared with lean individuals. Several mechanisms leading to hyperthyrotropinemia have been hypothesized.Objective and hypotheses: To compare thyroid function and autoimmunity in normal, overweight and obese healthy children and adolescents in our population. To analyse any metabolic risk factor related to hyperthyrotropinemia...

Background: DLK1 (PREF1) is a key inhibitor of adipogenesis and adipocyte differentiation. Adipose tissue expansion depends on adequate adipocyte differentiation. However, whether lower DLK1 expression facilitates adipose tissue expansion following fetal growth restriction is so far unknown.Objective and hypotheses: To study the expression of DLK1 in the adipose tissue of prenatally growth-restricted rats and its relat...

Background: Gonadal function is altered up to 25% in patients who suffered cancer in childhood. Cryopreservation of ovarian tissue (COT) is an option for preserving fertility.Aims and objective: To establish the prevalence of primary hypogonadism (PH) in children with cancer after hematopoietic cell transplantation (HCT). To analyse the variables that predict progression to PH.Methods: Retrospective cohort study. Patients aged 0 to...

Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

Differences of sex development (DSD) occurs when the development of chromosomal sex, gonadal or internal/external genitalia is atypical. It has an incidence of 1: 1000-4500 live born children. New chromosomal array technologies (SNP-array) can analyze the genome of the individual providing information of copy number variation (CNV) of specific chromosomal regions helping to identified pathogenic variants that could explain the etiology of the DSD. This study aims to analyze th...
