Successful Immune Tolerance Induction in the First Case of Neutralizing Antibody Mediated Loss of Efficacy of Asfotase Alfa Treatment in Hypophosphatasia

Martos-Moreno Gabriel A , Gonzalez-Vicent Marta , Sebastian Elena , Argente Jesus

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...

Expression of ZnT8 Transporter in Thyroid Tissues from Patients with Immune and Non-Immune Thyroid Diseases

Bossowski Artur , Reszec Joanna , Polnik Dariusz , Gasowska Marta , Niklinska Wieslawa

Introduction: Zinc homeostasis is regulated by ZnT and Zip zinc transporters. Zinc transporter 8 (ZnT8) is localized in insulin containing secretory granule membrane and transports zinc from the cytosol into the vesicles. ZnT8 was identified on peripheral lymphocytes, in subcutaneous adipose tissue, in a pancreatic β-cells and extra-pancreatic endocrine glands including pituitary, adrenal and thyroid. Autoantibodies to the ZnT8 are detected in the majority of type 1 diabe...

Recognition of a Sequence: More Growth before Birth, Longer Telomeres at Birth, More Lean Mass after Birth

de Zegher Francis , Diaz Marta , Lopez-Bermejo Abel , Ibanez Lourdes

Background: Telomere length at birth is a major determinant of telomere length in late adulthood. However, the prenatal setting of telomere length is poorly understood. Individuals born large from non-diabetic mothers are at lower risk for later-life disorders than those born small, a feature of their longer health span being a higher lean mass that provides more muscle strength and that is already present in infancy.Objective, hypotheses & methods: ...

Do Children with Down Syndrome Show Lipid Profile Disorders?

Zimny Dominika , Szatkowska Marta , Maciaszek Julian , Machaj Mikolaj , Barg Ewa

Background: People with Down syndrome (DS) are considered to be atherosclerosis-free. However, obesity predispositions and thyroid gland dysfunction that accompanies this syndrome can influence on the heart ischemic risk. The aim of the study was the evaluation of lipid profile of children with DS and estimation of omega-3 supplementation effect on serum lipid profile.Materials and methods: The group constituted 69 children with DS (41 boys), average age...

Bone, Growth Plate and Mineral Metabolism

Baroncelli Marta , Raimann Adalbert , Padidela Raja , Nilsson Ola ,

The skeletal research field develops rapidly and has produced several exciting findings in the last year and includes advances in the treatment of rare skeletal disorders and an ever deeper understanding into the fundamental molecular mechanisms that control skeletal development, metabolism, growth, and mineralization. The targeting of the C-type natriuretic peptide (CNP) pathway and options to directly antagonize the overactivity of the FGFR3 pathway in achondroplasia continu...

Growth failure in aggrecan haploinsufficiency is due to a decrease in growth plate matrix volume and hypertrophic cell size

Bendre Ameya , Ottosson Lars , Baroncelli Marta , Dou Zelong , Nilsson Ola

Background: Heterozygous loss-of-function mutations in the aggrecan gene (ACAN) cause autosomal dominant short stature with advanced bone age, early-onset osteoarthritis and intervertebral disc disease (SSOAOD; OMIM#165800). ACAN mutations is a relatively common finding in idiopathic short stature (ISS) and has been reported to be the cause of growth failure in approximately 2% of children with ISS. However, the underlying cellular and molecular mechanisms by ...

A challenging case of Pituitary Gigantism

Chandwani Manju , Subbarayan Anbezhil , Levy Miles , Korbontis Marta

A 4.9-year-old girl presented with a 6-month history of excessive body odour and suspected breast development. Family history was significant for presence of Lynch syndrome in both her father and paternal grandmother. At presentation, she was pre-pubertal but tall for her age. Her height was 124 cm (SDS 3.5), and weight was 27.1 kg (SDS 2.69). Her height velocity was accelerated at 15 cm/year and bone age was advanced at 7 years. Investigations revealed an elevated IGF-1 (500 ...

Low-dose pioglitazone for polycystic ovary syndrome in adolescent girls:differential fat-mass redistribution by HOTAIR rs1443512 genotype

de Zegher Francis , Diaz Marta , Ibañez Lourdes

Introduction: Adolescent polycystic ovary syndrome (PCOS) is characterized by androgen excess and oligo-amenorrhea, and often results from ectopic lipid storage due to a mismatch between early adipogenesis and later lipogenesis. Endogenous HOTAIR and exogenous pioglitazone are enhancers of subcutaneous adipogenesis, particularly in the gluteofemoral region. The A allele of HOTAIR rs1443512 is an equivalent of a natural knock-down and is thus a candidate to inf...

Pediatric Hyperthyroidism in the Time of COVID-19: An Updated Presentation Analysis

Sol Ventura Paula , Gonzalez Alba , Valls Aina , Murillo Marta

Abstract: The SARS-CoV-2 virus uses ACE2 combined with the transmembrane-protease TMPRSS2 to enter and infect thyroid follicular cells. Studies have reported a higher incidence of hyperthyroidism cases during the COVID-19 pandemic compared to pre-pandemic periods. Studies have also been reported cases of thyroid dysfunction early after mass covid vaccinations. However, there are insufficient data to confirm these associations in children.<p class="abstext"...
