Background: Silver Russell syndrome (SRS) is a heterogeneous disorder characterised by intrauterine and post-natal growth retardation, relative macrocephaly, protruding forehead, feeding difficulties and body asymmetry. Variants in HMGA2 are a rare cause of SRS and despite strong evidence for the crucial role of HMGA2 in growth regulation, its functional role in human linear growth is unclear.Methods: Patients w...

Background: The diagnosis of GH deficiency in children is based on clinical, auxological, radiographic and biochemical criteria which include response to Pharmacological Estimulation Tests (PhT). It is well known that GH concentrations vary according to the assay method used. Currently in our population, the proposed cut-off value of serum GH PhT is 4.7 ng/ml measured by ICMA using the IRP 98/574.Objective and hypotheses: The aims of this study were to d...

The increase in childhood obesity prevalence led to the establishment of a monographic obesity clinic since 2009 in our Department. To date, over 1600 patients have been visited, focusing on early onset severity and generating a valuable dataset on the characteristics of these patients (“The Madrid cohort”). This has allowed the performance of genomic and genetic studies, which have led to the demonstration of a genetic background, underlying the development of the d...

Introduction: non-insulin-dependent diabetes mellitus (type II) is an increasing problem in childhood. With the advancement of genetic testing and genome-wide association studies, mutations in genes causing loss or dysfunction of the pancreatic cell have been associated with type II diabetes. A heterozygous mutation of the MAPK8IP1 (Mitogen-activated protein kinase 8 interacting protein 1) gene is associated with a rare form of diabetes with few cases reported...

The coronavirus disease (COVID-19) pandemic brought with it a state of alarm as of March 14, 2020, which implied a restriction on the mobility of the general population and home confinement. One of the main concerns raised by isolation was the substantial reduction in energy expenditure due to children spending more time sitting or participating in activities that involve very low rates of energy expenditure, such as watching television, managing the different networks social ...

Background: Pituitary stalk interruption syndrome (PSIS) is characterized by the absence of the pituitary stalk, pituitary hypoplasia and an ectopic posterior pituitary.Objective: We aimed to retrospectively analyze the clinical, auxological, biochemical, and radiological findings in Spanish patients with PSIS.Patients and results: Of 27 patients, 25% were female and 75% male. Perinatal features, auxological and endocrine study at ...

Introduction: Adrenarche is characterized by the activation of androgen precursors which are released from the zona reticularis of the adrenal gland. Dehydroepiandosterone (DHEA) is a weak androgen and its conversion to slightly more potent androgens such as Dehydroepiandosterone- sulfate (DHEA-S) is thought to be responsible for the clinical signs of adrenarche. Premature adrenarche is one of the most common endocrine abnormalities causing concern among perip...

Introduction: Generation of neutralizing antibodies (Nab) is a complication in enzyme replacement therapies and can lead to loss of treatment efficacy. Asfotase alfa (AA) was recently approved as the first replacement therapy in severe hypophosphatasia (congenital deficiency of alkaline phosphatase [TNSALP]). We report a case of neutralizing antibody mediated loss of efficacy of AA treatment in hypophosphatasia and the successful result of immune tolerance ind...

Background: Dietary carbohydrate restriction in the treatment of obese adolescents could cause a substantial shift in the substrates used as an energy source, inducing changes on body composition and metabolism, but experience in this age range is limited.Objective: We assessed the influence of 6 months of dietary carbohydrate restriction on body composition and lipid and carbohydrate metabolism in obese adolescents.Method: Thirty-...

Background: Impaired glucose tolerance ((IGT), glucose ≥140mg/dl at 120’ in the oral-glucose-tolerance-test (OGTT)) is prevalent in childhood obesity. It is frequently reversed after weight loss, although an eventual role for metformin treatment has been postulated.Objective: To evaluate the benefits of metformin addition to conservative treatment on weight loss and IGT in obese children.Patients and methods: We studied ...
