Background: Low birth weight (LBW) followed by a rapid postnatal catch-up in weight predisposes individuals to a central distribution of body fat, which is reverted by metformin. Growth-and-differentiation-factor-15 (GDF15) plays an important role in the regulation of energy homeostasis, reducing food intake and lowering body weight. We aimed to assess whether GDF15 concentrations are raised by long-term metformin treatment in LBW/catch-up girls with precociou...

Background: Growth-and-differentiation factor-15 (GDF15) is a regulator of energy homeostasis, and is used as biomarker of several pathological states.Objectives: To assess longitudinally GDF15 concentrations in a cohort of infants born either appropriate- (AGA, n=70) or small-for-gestational-age (SGA, n=33), the latter known to be at increased risk for central adiposity and metabolic alteration...

Background: Studies aimed at elucidating the pathophysiology of obesity consistently describe it as a highly heterogeneous disorder at both clinical and molecular level. Despite rare monogenic forms and several regions of susceptibility have been defined, the genetic causes underlying the disease remain largely unknown.Objective and hypotheses: We aimed to identify novel genetic abnormalities in a cohort of Spanish children with severe non-syndromic earl...

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: Vitamin-D-dependent rickets 1A (VDDR-1A) is a extremely rare, autosomic recessive genetic form of rickets caused by a defect in vitamin D 1α-hydroxylase enzyme which leads to low levels of 1,25-(OH) vitamin D.Herein, we report two Moroccan sisters R.E. and N.E. (respectively 3 and 15 months old), born from consanguineous parents, who presented with psychomotor retardation and failure to thrive.<str...

The majority of treated obese children fail the goals set in the medium-long term or do not show themselves up at the short term follow up. These results, which do not improve even with the proliferation of facilities aimed to the treatment of obesity and of its complications, pose serious questions on how to make the best use of scarce resources available by the National health system. We have visited, between 2013 and 2015, 378 seriously obese children (>2 DS from nation...

Introduction: The evolution of Hashimoto Thyroiditis (HT) has been investigated by several studies both in pediatric and adult age. However, there are limited data on the progression of the disease from childhood to adulthood.Objective: Aim of the study was to describe the evolution of thyroid function in children with HT from childhood to young adulthood.Patients and Methods: The diagnosis of HT was defined by the presence of anti...

Introduction: Delayed puberty (DP), affecting over 2% of adolescents, is defined as pubertal onset 2-2.5 SDs later than the general population. The most common underlying aetiology is self-limited DP (SLDP). However, this can be difficult to differentiate from the more severe condition congenital hypogonadotrophic hypogonadism (HH), especially on first presentation of an adolescent patient with DP. This study sought to elucidate phenotypic and genotypic discre...

Case presentation: G. 15 years 8 months; H 180 cm; P 149.6 kg, BMI 46 kg/m2, second born, father obese, healthy mother and two brothers, no familiarity for T1DM/T2DM, no gestational diabetes. Bronchial asthma, since 2-year-old important weight increase. Flue, polyuria, polydipsia, 12 kg loss in 15 days, anorexia since 5 days, vomit. Hospitalized for tachycardia, dyspnea, and asthenia. On arrival: serious dehydration, Kussmaul breathing, neck subcutaneous emphysema, ...

The obesity epidemic continues to be a dramatic problem in the developed world despite attempts to curtail its rise. Reducing energy intake and/or increasing energy expenditure can result in weight loss; however, if one returns to their poor lifestyle habits the previous weight is not only recuperated, but often surpassed.We hypothesized that although a normal body weight may be achieved, the hypothalamic circuits controlling appetite and energy expendit...
