Serum steroid metabolome dynamics during infancy: a prospective, longitudinal cohort of healthy boys

Siegfried Busch Alexander , Lindhardt Ljubicic Mariee , N. Upners Emmie , B. Fischer Margit , P. Hagen Casper , Frederiksen Hanne , Juul Anders

Background: The circulating steroid metabolome in boys undergoes significant changes during infancy reflecting functional and structural rearrangements of the adrenal glands as well as the transient activity of the hypothalamic–pituitary–gonadal axis, also called minipuberty. Studies investigating the serum steroid metabolome dynamics during infancy in a longitudinal manner are however sparse.Objective: We ai...

Are pappalysins and stanniocalcins involved in modifying the bioavailability of IGF-I in children with onset of type 1 diabetes mellitus?

Güemes Maria , Canelles Sandra , Martín-Rivada Álvaro , Corredor Beatriz , Barrios Vicente , Argente Jesús

Introduction: Both poor and optimal metabolic control of type 1 diabetes mellitus (T1DM) in children can impact longitudinal growth. A decrease in insulin-like growth factor (IGF)-I and its binding protein 3 (IGFBP3) has been described in these patients. New growth regulatory factors [pappalysins (PAPP-As) and stanniocalcins (STCs)] could modulate the bioavailability of IGFs by regulating the concentrations of intact and free IGFBPs.<str...

Objective: Secondary osteoporosis has a high rate of accompanying chronic diseases. We aimed to review the clinical and laboratory features, underlying causes, Dual Energy X-ray Absorptiometry (DEXA) results before and after treatment of patients diagnosed with secondary osteoporosis and to determine the relationship between this condition and fracture rates.Methods: This study was designed as a single-center, descriptiv...

Syndromic Patients with Negative Islet Autoantibodies should be Tested for Mongenic Diabetes: Lessons from Patient with Trmt10a Mutation

Siklar Zeynep , Colclough Kevin , Patel Kashyap A , Cetin Tuğba , Berberoğlu Merih

Aim: Glucose metabolism can affect by several genes, and some of them represent distictive clinical and laboratory features. tRNA methyltransferase 10 homologue A (TRMT10A) gene is a tRNA methyl transferase, and localised to the nucleolus, where tRNA modifications occur. Very recently, a novel syndrome of abnormal glucose homeostasis or nonautoimmune diabetes associated with microcephaly, epilepsy, intellectual disability, failure to thrive, delayed puberty caused by ...

Central Precocious Puberty Appeared in Infancy Period in a Patient of Sotos Syndrome

Cetin Tuğba , Ceylaner Serdar , Şıklar Zeynep , Berberoğlu Merih

Background: Sotos syndrome is a rare syndrome; with distinctive clinical findings include typical facial appearance, learning disability; and overgrowth. Advanced bone age can be detected in some cases while precocious puberty reported only in two cases until now.Case: A 6,5 months of age male infant admitted to clinic with neuromotor delay and macrogenitalia. He was second child of unrelated healthy parents, and birth-weight was 4200 g. In physical exa...

Biovascular Markers in Children with Kabuki Syndrome

Schott Dina , Kooger Berbel , Bierau Jorgen , Gerver Willem-Jan , Zimmermann Luc , Stumpel Constance

Background: Asymmetric dimethylarginine (ADMA) is an endogenous competitive inhibitor of endothelial nitric oxide synthase (NOS), which prevents synthesis of nitric oxide (NO). Low levels of NO are associated with endothelial dysfunction and an increased risk of cardiovascular disease. Diseases associated with high levels of ADMA include metabolic syndrome, chronic kidney disease, diabetes mellitus, insulin resistance, hyperthyroidism and multiple organ failure. Notable, GH tr...

Dynamic changes of reproductive hormones in male minipuberty: Temporal dissociation of Leydig- and Sertoli-cell activity

S. Busch Alexander , Lindhardt Ljubicic Marie , N Upners Emmie , Bistrup Fischer Margit , Lau Raket Lars , Frederiksen Hanne , Albrethsen Jakob , Holm Johannsen Trine , P Hagen Casper , Juul Anders

Background: The male Hypothalamic-Pituitary-Gonadal (HPG) axis is transiently active during the first months of life with surging serum concentrations of reproductive hormones. This period, termed minipuberty, promotes masculinization, including testicular, and penile growth, as well as further testicular descent in males. It appears to be essential for priming specific cell types, i.e. Sertoli-, Leydig-, and germ cells, including subsequent growth and maturat...

Gene Chimeras Involving CYP21A2 and TNXB Genes in Spanish Patients with Congenital Adrenal Hyperplasia (CAH)

Martínez Figueras Laura , Escribano Muñoz Arancha , Carcavilla Atilano , Berthold Laura , Llorente Martín Elena , Arriba Domènech María , Ezquieta Zubicaray Begoña

Background-Aim: Gene rearrangements between CYP21A2, TNXB and their homologous pseudogenes (CYP21A1P,TNXA) result in chimeric genes, responsible for the CAHX syndrome. CAHX patients show CAH and Ehlers-Danlos syndrome (EDS) symptoms. Three CAHX chimeras with different clinical severity are described: CH1 (including 120bp deletion in exon 35), CH2 and CH3. The small size and few series reported so far warrant further studies ...

Increased Basal Levels of 17-Hydroxyprogesterone In The Covid ERA: Must We Change The Cut-Off Point To Request Acth Test?

Laura Bertholt Zuber M. , Alonso Rubio Pablo , Palenzuela Revuelta Inmaculada , Pozas Mariscal Sara , Lavín Gómez Bernardo , Teresa Garcia Unzueta M.

Background: 17-hydroxyprogesterone (17-OHP) basal levels greater than 2ng/ml has been related to the need to request an ACTH test to dismiss non-classic congenital adrenal hyperplasia. We have seen an increase in baseline levels in 2021 compared to 2020.Objectives: To determine how many of the tests that were requested due to a high basal 17-OHP value, were positive. Assess the need to modify the cut-off points to reques...

Screening for disordered eating behaviours and associated factors in children and adolescents with type 1 diabetes

Barsal Çetiner Ebru , Donbaloğlu Zeynep , Singin Berna , Aydın Behram Bilge , Bedel Aynur , Parlak Mesut , Ünver Tuhan Hale

Introduction and Purpose: Patients with type 1 diabetes mellitus must be extremely concerned with what they eat and their insulin dose as part of their treatment. Therefore, the risk of eating disorders increases in this patient group. This study, it was aimed to determine the disordered eating behaviors of patients with Type 1 DM and to evaluate the results of the general demographic characteristics, diabetes care behaviors, and quality of life scale that whi...
