Background: GH deficiency may not persist into adulthood. Thus, it is recommended to reassess it after reaching adult height. However, according to stimulation tests, they have poor specificity, reproducibility, and poor standardization of hormonal measurement, and they are expensive and involve risks.Objective and hypotheses: Establish if IGF1 would be a better reassessing method than stimulation tests in adult GH defic...

Background: CYP11A1 gene encodes the cholesterol side-chain cleavage enzyme, P450scc, which plays a key role in the initial steps of steroidogenesis. CYP11A1 insufficiency lead to a variable phenotype ranging from severe early onset primary adrenal insufficiency (PAI) in the neonatal period,with 46,XY DSD; to late-onset PAI with normal genitalia.Objective: Detail the phenotype of a family sharing newly described...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. The association between T2D and non-alcoholic fatty liver disease (NAFLD) has been described; this increases the risk of coronary heart disease (CHD). Recent evidence suggests that sizes and composition of HDL may be more important that HDL-C levels in predicting CHD. There is not data regarding the HDL subclasses distribution and composition in T2D youths with hepatic steatosis (HE).<p c...

Introduction: The proopiomelanocortin is a polypeptide of many biologically active peptides involved in many key functions which have not yet been clarified. The mutation in the gene encoding this polypeptide is associated with a clinical trials characterized by early-onset obesity, terciary adrenal insufficiency, and alteration of pigmentation. Eight cases with known genetic mutation have been published.Case report: Newborn male 27 days old from North A...

Background: Small-for-gestational-age (SGA) newborn infants (NB) may present long-term comorbidities influencing their metabolism, growth and/or development. Although their serum proteome is unknown, altered expression of the proteome profile may provide information on their physiopathology and lead to the discovery of biomarkers for postnatal complications.Aim: To detect changes in the serum proteome in SGA-NB vs adequate-for-gestational-age (AGA) newbo...

Background: We have recently reported a BMI-SDS increase in girls with Turner syndrome (TS) treated with growth hormone (GH) (1).Objective and hypothesis: We hypothesise that puberty induction in TS is associated with weight gain.Method: We analysed the weight changes (BMI-SDS) of 888 girls with TS in the Pfizer International Growth Database (KIGS). Overweight was defined by a BMI >90th percentile and obesity by a BMI >97th...

Introduction: The results of the phase III clinical trial that evaluated the efficacy and safety of the biosimilar recombinant human GH - rhGH - (Omnitrope®, Sandoz) on the treatment of Spanish children with GH deficiency were published in 2011. At the end of the study those patients that were still growing remained on treatment within the usual clinical practice.Objective: To know the values of adult height of the children who participat...

Introduction: Published studies on pubertal growth of SGA patients on GH therapy are scarce. An earlier and shorter duration of puberty has been described. Treatment optimization may be necessary and also know their influence on adult height.Objetives: Analyse the evolution of height durig puberty in SGA patients treated with GH. Asses the age of onset of puberty and its relationship to adult and target height.Methods: Retrospectiv...

Background: Aromatase deficiency is a rare autosomal recessive disorder produced by CYP19 gene mutations. 46XX affected patients presented with ambiguous genitalia leading to early identification. Most 46XY affected patients presented normal external genitalia and the condition often remains undiagnosed until late puberty. Information on pubertal development in affected boys is scarce since to the present date only two patients, younger than 4 years of age, without lo...

Introduction: The extracellular calcium-sensing receptor (CaSR) enables the parathyroid glands and other CaSR-expressing cells involved in calcium homeostasis to sense alterations in calcium serum concentrations. Mutations in the CASR gene may produce gain or loss in its activity. Activating mutations cause a hypocalcaemic syndrome of varying severity, as autosomal-dominant hypocalcaemia or Bartter’s syndrome.Case report: We describe a 6 months infa...
