Trientine Treatment Mimicking Severe Hyperandrogenism

Binder Gerhard , Weber Karin , Wudy Stefan A. , Holterhus Paul-Martin , Hartleif Stefan

Drugs can interfere with immunoassays causing false measurements. Trientine (triethylene tetramine dihydrochloride) is a chelator of copper and is used in the treatment of patients with Wilson's disease as alternative for penicillamine. Trientine mainly increases urinary copper excretion leading to a negative copper balance. Serum concentrations of trientine reached under treatment are not known. This is the first report of an interference of trientine with two chemilumine...

Nephrocalcinosis in Children with X-Linked Hypophosphatemia: Prevalence and Risks Factors

de Truchis Camille , Zhukouskaya Volha , Auger Martin , Rothenbuhler Anya , Linglart Agnès , Grapin Mathilde

X-linked hypophosphatemia (XLH) is diagnosed in children with clinical and or radiological signs of rickets, impaired growth velocity, low serum phosphate levels associated with renal phosphate wasting, in the absence of vitamin D or calcium deficiency. Conventional treatment is made of phosphate and active vitamin D. However, nephrocalcinosis has been identified as a complication of this therapy. Its prevalence is about 25-40% in adult XLH treated patients. It was never c...

Clinical Outcomes in Primary Empty Sella (ES) Syndrome in Childhood-Onset Growth Hormone Deficiency: Data from KIGS (Pfizer International Growth Database)

Maghnie Mohamad , Carlsson Martin , Aydin Ferah , Camacho-Hübner Cecilia

Background: The incidence of ES in children varies greatly depending on the population surveyed, ranging from 1.2%-9% to 68% (children without and with known endocrinopathies, respectively). MRI is the main diagnostic tool for screening pituitary and in a previous KIGS study, 3.0% of patients with GHD were identified with ES and 7.8% with pituitary hypoplasia (Maghnie et al, EJE (2013).Aim: T...

Adult Height Prediction by Bone Age Determination in Children with Idiopathic Growth Hormone Deficiency (IGHD): Analysis of KIGS Data

Reinehr Thomas , Carlsson Martin , Chrysis Dionisios , Camacho-Hübner Cecilia

Background: The precision of adult height prediction by bone age determination in children with idiopathic growth hormone deficiency (IGHD) is unknown.Patients and Methods: The near adult height (NAH) of patients with IGHD with prepubertal onset of growth hormone treatment (GH) in the KIGS database was compared to adult height prediction based on bone ages (BA) >7 years using the Bailey Pinneau (BP) or Tanner-Whiteho...

Insights into the Regulation of Androgen Biosynthesis from Males with Congenital Hypogonadotropic Hypogonadism: Quantification of Bioactive Steroid Hormones Reveals Differences Between Gonadotropin Replacement and Testosterone Replacement

Rohayem Julia , Holterhus Paul-Martin , Kliesch Sabine , Nieschlag Eberhard , Zitzmann Michael , Kulle Alexandra

Background: In males with congenital hypogonadotropic hypogonadism (CHH), LH/FSH stimulation of gonads is deficient. In clinical practice, two hormone replacement strategies are employed to induce and maintain virilisation: Treatment with testosterone and gonadotropin replacement with hCG/rFSH.Objective: To delineate the role of gonadotropins in pathways of male androgen biosynthesis and to thereby better define the gona...

Does Karyotyping and in situ Hybridization from Three Different Germ Layers Elucidate Low Bone Mineral Density in Turner Syndrome?

Soucek Ondrej , Lebl Jan , Zapletalova Jirina , Vrbicka Dita , Adamova Katerina , Prochazka Martin , Klaskova Eva

Background: Turner syndrome (TS) is caused by a total or partial loss of one X chromosome. Typical features include short stature and primary amenorrhoea. In addition, decreasing trabecular bone mineral density (BMD) and increasing cortical BMD during puberty has been reported at the radius. As chromosomal aberration remains a probable cause of bone changes in TS, we aimed to elucidate whether the karyotype differs among the tissues originating from the three ...

Polydipsia, Hyponatremia and a Biochemical Profile of Aldosterone Synthase Deficiency

Reinauer Christina , Förtsch Katharina , Meissner Thomas , Mayatepek Ertan , Holterhus Paul Martin , Kummer Sebastian

Background: Aldosterone synthase deficiency (ASD) is caused by biallelic inactivating CYP11B2 variants. Infants mainly present with failure to thrive and salt wasting in early infancy. Moreover, different factors may cause downregulation of aldosterone synthase and secondary deficiency.Objective and Hypotheses: We present a toddler with polyuria and polydipsia and steroid hormone precursors suggestive of ASD, bu...

Metabolic Effects of Growth Hormone Treatment in Short Prepubertal Children: A Double-Blinded Randomized Clinical Trial

Tidblad Anders , Gustafsson Jan , Marcus Claude , Ritzén Martin , Ekström Klas

Objective: Growth hormone (GH) is a central hormone for regulating linear growth during childhood and also highly involved in metabolism of lipids, carbohydrates and protein. However, few studies report on how treatment with GH during childhood influences metabolic parameters. Our aim was to investigate metabolic effects of different doses of GH in short children with GH peak levels in the low normal range.Design: Thirty...

Does the Anogenital Distance Predict Outcome of Hypospadias Repair?

Springer Alexander , Riedl Stefan , Tonnhofer Ursula , Hiess Manuela , Metzelder Martin , Hebenstreit Doris

Purpose: The anogenital distance (AGD) is androgen action dependent. It is sexually dimorphic and seems to be shorter in androgen-action related diseases like hypospadias. In this study we sought to determine whether the AGD is predictive for surgical outcome in hypospadias repair.Material and Methods: Patients were collected prospectively. AGD was measured in OR prior to surgery by 2 surgeons (blinded, each 3 times). Ou...

Effects of IGF-1R Nuclear Localization in Glioblastoma Cells

Martin Ayelen , Clement Florencia , Venara Marcela , Bergada Ignacio , Gutierrez Mariana , Pennisi Patricia

Background: CNS tumors are the most frequent solid tumors in pediatric population. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. Recently, we have shown that in paediatric gliomas, IGF-1R nuclear localization was significantly associated with both high grade tumours and increased risk of death, suggesting that nuclear IGF-1R localization may contribute to an aggressive behaviour of these tumours.<p class="...
