Background: Iodotyrosine deiodinase (DEHAL1) is a thyroidal enzyme that deiodinates mono- and diiodtyrosines (MIT, DIT) and recycles iodine, essential for synthesis of thyroid hormone. Iodotyrosine deiodinase deficiency leads to hypothyroidism, goiter and variable mental retardation. The age for clinical onset was reportedly very diverse, allegedly related to individual iodine nutrition.Clinical case: We report on a boy, offspring of consanguineous paren...

Background: There is increasing interest in vitamin D nutrition during pregnancy because of widespread reports of a high prevalence of low vitamin D status in pregnant women in high-latitude areas. It has been related to adverse events in mother and child. Neonates present a greater risk of hypocalcaemia, rickets and a higher incidence of infections during the 1st year of life.Objective and hypotheses: Real situation of pregnant women and newborn in rela...

Introduction: Prader–Willi syndrome (PWS) is a genetic disorder caused by the lack of expression of genes on the paternally inherited chromosome 15q11.2-q13 region. Clinical picture of PWS changes across life stages. PWS is characterized by endocrine abnormalities, such as growth hormone (GH) deficiency, obesity, central adrenal insufficiency, hypothyroidism, hypogonadism, and complex behavioural and intellectual difficulties. The recombinant human growt...

Objectives: Somatrogon is a long-acting recombinant human growth hormone (GH) approved in the EU and other countries for once-weekly treatment of pediatric patients with GH deficiency (GHD). In this analysis, height outcomes of somatrogon-treated patients in a phase 3 trial (CP-4-006) were compared with historical data from matched somatropin-treated patients enrolled in KIGS.Methods: In trial CP-4-006, patients were ran...

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease that regulates IGF-1 availability, causes postnatal growth failure and changes in bone size and density in humans and mice. The present study aimed to determine the effects of daily administration (from PND5 to PND35) of recombinant murine (rm) PAPP-A2, in comparison to rmGH and rmIGF1, on mouse auxology and bone microarchitecture in homozygous Pappa2 knock-out (ko/ko) mice of both sexes. Hormone treatm...

The growth hormone (GH)-insulin-like growth factor (IGF-1) system is essential for optimal human growth and energy homeostasis. Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease involved in the liberation of free IGF-1, leads to problems in growth and bone density in humans and mice. Patients with PAPP-A2 deficiency also present lower body mass and mild glucose intolerance. The present study aimed to determine the influence of 1 month of high carbohydr...

Introduction: Nephroblastoma or Wilms tumor is the most common pediatric abdominal malignancy. Typically, it is found in children younger than 5 years old, girls being more likely to have Wilms tumor than boys. The etiology of the disease is genetic, due to alteration in the development of the genitourinary tract.[1] Treatment is represented by surgery (unilateral nephrectomy), chemo- and radio-therapy. Paraneoplastic endocrine disorders may occur, but there a...

Background: A close association has been reported between obesity and renal damage in adults, but evidence in childhood is still limited.Methods: We retrospectively studied 396 children and adolescents with obesity. Clinical, biochemical, and instrumental evaluations were performed. Patients were stratified according to the metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) phenotypes. Kidney d...

The proband is a Caucasian girl with primary amenorrhea and no breast development at the age of 16 11/12 yrs. Unrelated parents; an older brother in good health and a twin brother (GA 31 days; BW 1450g) with reported agenesis of the corpus callosum and socio-emotional behavioral problems. The mother (menarche 14 yrs. and bicornuate uterus) presented four early spontaneous abortions and one stillborn fetus (46, XX) in the 6th month of pregnancy; remaining negative family histor...

Introduction: Non-alcoholic fatty liver disease (NAFLD) is diagnosed in up to 60% of overweight children. Diagnosis and management of NAFLD is challenging due to the lack of non-invasive imaging biomarkers. Ultrasound (US) is the most widely non-invasive method used to identify liver steatosis, however it has low sensitivity to detect mild steatosis and to quantify hepatic fibrosis. Liver Elastography (LE) is a non-invasive methodology used to evaluate hep...
