Cortoic Acids: Renaissance of a Forgotten Class of Steroids

Schauermann Marcel , Wachter Ulrich A. , Homoki Janos , Hartmann Michaela F. , Hua Yifan , Remer Thomas , Wudy Stefan A. ,

Initially discovered in the 1970s, the C21 steroidal acids α-cortolic acid, β-cortolic acid, α-cortolonic acid and β-cortolonic acid present the terminal oxidative products of cortisol metabolism. Undergoing renal elimination, these cortoic acids have been assumed to represent up to 25% of total urinary cortisol metabolites. However, their analysis has been difficult, only few data has been published in adults, and this class of steroids has beco...

Establishment of Clinical and Lab Algorithms for the Identification Carriers of Mutations in CYP21A2 – A Study of 768 Children and Adolescents

Meinel Jakob , Finckh Ulrich , Schuster Andreas , Haverkamp Thomas , Richter-Unruh Annette

Background: Bi-allelic mutations of CYP21A2 encoding 21-hydroxylase are the most frequent cause of congenital adrenal hyperplasia (CAH). Non-classical CAH (NCCAH) or even just hyperandrogenism may be caused by mild or mono-allelic (single) heterozygous mutations of CYP21A2. These mutations are associated either with elevated basal or ACTH-stimulated levels of 17-hydroxyprogesterone (17OHP) in blood.Objective and hypotheses: The objective of this study wa...

Role of the Metabotropic mGlu5 Glutamate Receptor in the Initiation of Puberty and Reproduction in Female Mice

Inta Ioana , De Angelis Roberto , Domonkos Emese , Lankisch Katja , Boehm Ulrich , Gass Peter , Bettendorf Markus

Background: The neuroendocrine mechanisms of the initiation of puberty are still incompletely deciphered. Accumulating data indicate a main role of the glutamate system in regulating hypothalamic GnRH. However, the underlying neurobiological mechanisms are yet poorly investigated. Mice lacking metabotropic mGlu5 receptors (mGluR5) show sever unexplained infertility.Objective and hypotheses: We aimed in the present study to analyze the specific role of mG...

Specific Hypothalamic Activation Pattern by mGlu5 Receptor Blockade in vivo During Pubertal Development in Female Mice

Inta Ioana , de Angelis Roberto , Lankisch Katja , Dormann Christof , Pfeiffer Natascha , Boehm Ulrich , Gass Peter , Bettendorf Markus

Background: Puberty is characterised by important changes of brain networks. The glutamate system plays a main role in modulating the onset of puberty as shown for NMDA receptor agonists. However, the underlying mechanisms are poorly understood. Metabotropic mGlu5 receptors (mGluR5) are tightly linked to NMDA receptors. The effect of mGluR5 blockade on neurohormonal mechanisms in puberty initiation were not studied yet.Objective and hypotheses: To invest...

Histological Evaluation of Patients with Partial Gonadal Dysgenesis and NR5A1 Mutations: Review in Leydig and Germ Cell Pattern

de Andrade Juliana Gabriel Ribeiro , Werner Ralf , Fabbri Helena Campos , Guerra-Junior Gil , Maciel-Guerra Andrea Trevas , de Mello Maricilda Palandi , Holl-Ulrich Konstanze , Hiort Olaf

Background: Recent data describe that the gonads of patients with partial gonadal dysgenesis (PGD) and mutation in the NR5A1 gene can present with a different histological pattern.Objective and hypotheses: To evaluate histological aspects of PGD caused by NR5A1 mutations.Method: Five patients with PGD, a history of gonadal biopsy or gonadectomy and confirmed mutation on NR5A1 gene were selected from a Bra...

Pathogenic Mutations and Variants in KSR2 in a Cohort of Obese Children

Körber Ingrid , Sowada Nadine , Schirmer Melanie , Herrmann Gloria , Nunziata Adriana , Bald Martin , Ehehalt Stefan , Paetow Ulrich , Ohlenschläger Ute , Rabenstein Hannah , Siebert Reiner , von Schnurbein Julia , Wabitsch Martin

Background: Kinase suppressor of Ras 2 (KSR2) gene codes for a scaffold protein modulating intracellular pathways that involve MEK/BRAF cascade and AMPK signaling. KSR2 plays an important role in energy balance regulation, and KSR2 mutations were reported to be associated with obesity and insulin resistance in mice and humans. In transfected cells, several KSR2 mutations lead to impaired fatty acid oxidation, which improved under met...

Pseudoexon Activation in Nicotinamide Nucleotide Transhydrogenase in Two Siblings with Familial Glucocorticoid Deficiency

Chan Li , Novoselova Tatiana , Rath Shoshana , Carpenter Karen , Atkinson H , Dickinson Jan , Pachter Nick , Price G , Choong Cathy , Metherell Lou

Background: Two siblings of non-consanguineous parents presented with FGD, demonstrated by ACTH resistance with glucocorticoid but not mineralocorticoid deficiency. The proband presented at 21 months, unresponsive with hypoglycaemia (BGL 1.5 mmol/l). Endocrine evaluation subsequent to resuscitation indicated adrenal insufficiency with elevated ACTH. Hydrocortisone therapy was commenced. A sibling, 4 years younger than the proband had a short Synacthen test (SST) performed on d...

A 19-Year-Old Adolescent with Short Stature and Scrotal Tumour

Heldt Katrin , L'Allemand Dagmar , Waibel Peter

Introduction: Primordial short stature can have many different causes. In addition to maternal factors (e.g. placental insufficiency), genetic or skeletal disorders may be found in the child. It is important to identify the underlying aetiology in time, since not only the risk of diabetes is increased, but also the prevalence of insufficient gonadal function and malignancy, e.g. in mixed gonadal dysgenesis (MGD).Case report: A 19 year old adolescent pres...

Turner Syndrome with Neonatal Revelation: Knowing How to Think About It

Ould Mohand Ouamer , Fernane Leila , Sebar Khadidja , Lebane Djamil

Introduction: urner's syndrome (TS) is a rare genetic disorder related to the total or partial absence of an X chromosome, affecting 1/2 500 newborns of female sex. It associates almost steadily a delay in stature and ovarian failure with infertility.The other anomalies are inconstant: morphological features of variable intensity, associated malformations and an increased risk of subsequent acquired diseases.The diagnosis of certainty is established after ...
