Short stature is diagnosed when height is significantly below the average of the general population for that person’s age and sex. To elucidate the factors that modify disease severity/penetrance in short stature, we have studied a three-generation family with SHOX deficiency. We have found that the retinoic acid degrading enzyme CYP26C1 is a modifier for SHOX deficiency phenotypes towards the more severe clinical manifestations (Leri-Weill dyschondrosteosis) and confirme...

Background: Congenital adrenal hyperplasia (CAH) encompasses a group of autosomal recessive disorders which lead to impairment of steroid biosynthesis in the adrenals and gonads. 21-hydroxylase deficiency (21OHD) is the most common form of CAH (95%), followed by 11β-hydroxylase deficiency (11OHD) and 3β-dehydrogenase steroid dehydrogenase type 2 deficiency (3bHSD2). LC–MSMS based steroid analysis has become an increasingly important method for steroid analyses i...

Background: Early-onset severe obesity due to leptin deficiency typically results from a defect of leptin production or secretion due to mutations in the leptin gene. Recently we described a new form of leptin deficiency caused by bioinactivity of the hormone and associated with high circulating leptin levels (New England Journal of Medicine 2015 372 48–54).Method: Serum leptin was measured by ELISA. The leptin gene was seq...

Major Improvement in Parental Perception of their Children’s Height-Specific Quality of Life after 1 Year of GH Treatment: Our Experience with the QoLiSSY Questionnaire

Background: Short stature may be a source of social and affective stress in children and their parents, and thus impact negatively on their quality of life (QoL). Treatment by GH may improve QoL through normalisation of height.Objective: To evaluate height-specific QoL in short stature children after 1 year of GH treatment.Methods: Prospective study. Inclusion criteria were: having started GH treatment at Hôpital Necker-Enfant...

Severe Neonatal Hypoglycemia in the Newborn Despite Prenatal Diagnosed Cerebral Midline Malformations: a Review of Three Cases

Reschke Felix , Gemulla Gita , Flury Monika , Brenner Sebastian , Schuetzle Heike , Gurth Heidrun , Hahn Gabriele , Taut Heike , Glajzer Jack , Gottschalk Hans-Christian , Hubner Angela

Background: Brain abnormalities like cerebral midline malformations (CMM) can be detected by fetal sonography. CMM with neonatal hypopituitarism may cause severe hypoglycemia.Case presentation: We report about three cases of term eutrophic newborns, which all presented with severe neonatal hypoglycemia despite prenatally diagnosed CMM. All three patients were born vaginally and were immediately breastfed after normal postnatal adaptation. In the first ca...

Salivary profiles of 11 oxygenated androgens follow a diurnal rhythm in patients with congenital adrenal hyperplasia

Nowotny Hanna F. , Auer Matthias K. , Lottspeich Christian , Schmidt Heinrich , Dubinski Ilja , Bidlingmaier Martin , Adaway Jo , Hawley James , Keevil Brian , Reisch Nicole ,

Background: Routine biochemical assessment in patients with congenital adrenal hyperplasia (CAH) includes measurement of serum 17 hydroxyprogesterone (17OHP), androstenedione (A4) and testosterone (T) and their metabolites in urine. Several studies have also described 11 oxygenated 19 carbon (11oxC19) steroids as a clinically relevant androgenetic source and highlighted their potential as markers for evaluation of adrenal androgen excess in patients with 21-hy...

Monogenic obesity in children: focusing on SH2B1 deletion

Giannopoulou Eleni Z , Zorn Stefanie , Schirmer Melanie , Herrmann Gloria , Heger Sabine , Reinehr Thomas , Denzer Christian , Rabenstein Hannah , Schnurbein Julia von , Wabitsch Martin ,

Introduction: Monogenic obesity refers to a group of rare, early-onset forms of obesity and accounts for about 7% of patients with severe pediatric obesity. Recent reports demonstrate the emerging role of Src-homology-2 (SH2) B adaptor protein 1 (Sh2b1), an important component in the leptin-melanocortin pathway, as a key regulator of leptin and insulin signaling, with possible roles in the pathogenesis of obesity and diabetes. SH2B1 deletions are found to be a...

Introduction: The prevalence of pediatric type 2 diabetes (T2D) increased over the last 2 decades, related to the rise in obesity. Meanwhile, treatment options for T2D have evolved considerably. Therefore, we analyzed changes in treatment approaches for pediatric T2D over two decades.Material and Methods: Patients with T2D from 321 pediatric diabetes centers (Austria 24, Switzerland 2, Luxemburg 1, Germany 290) were reco...

Luppino Giovanni , Corica Domenico , Valenzise Mariella , Briguglia Silvana , Bertelloni Silvano , Li Pomi Alessandra , Wasniewska Malgorzata , Aversa Tommaso , Christian Denzer , Martin Wabitsch

Background: Disorders of sex development (DSD) are often due to disruption of the genetic programs that regulate gonad development. Some genes have been identified in these developmental pathways such as DAX-1, SOX-9, GATA-4 and others. The GATA-4 gene, located on chromosome 8p23.1, encodes GATA-binding protein 4 (GATA-4), a transcription factor that is essential for cardiac and gonadal development and sexual differentiation. Congenital heart disease (CHD) and...
