Background: 45,X/46,XY mosaicism is a rare karyotype with a broad phenotypic variation. In patients with a male or predominantly male phenotype, impaired genital development and statural growth have been observed, but little is known about long-term outcomes. Larger multicenter studies are needed.Objective and hypotheses: The aim of this study is to investigate long-term outcomes, namely gonadal function, growth and co-morbidities, in a larger group of m...

Pediatric transgender care from an endocrine perspective: experience over the past decade in a tertiary Swiss center

Mazzi Sara , Nussbaum Marie-Lou , Christa Flück E.

Gender dysphoria indicates a psychological distress due to any incongruence between biological sex and gender identity, while transgender identity refers to an individual, whose gender identity is the opposite of the biological sex. The number of gender dysphoric youth seeking hormonal care seems to rise worldwide. Therefore, numerous bioethical and medical controversies are raising about possible side effects of hormonal therapies, including interference with brain developmen...

Metformin Treatment Affects ACTH Receptor Activation and Downstream Signaling: A Potential Treatment for ACTH Excess Disorders and Management of Hyperandrogenic States

Parween Shaheena , Pandey Amit V. , Flueck Christa E.

Background: The peptide hormone adrenocorticotropin (ACTH or Corticotropin) is a major component of the stress response system in the Hypothalamus-Pituitary-Adrenal (HPA) axis. Under stress, it is secreted from the anterior pituitary and stimulates cortisol production from the adrenal cortex. Changes in ACTH production or action are associated with multiple disease conditions. In clinical situations like Cushing's disease, ectopic ACTH syndrome and congeni...

Virilization of a Girl at Puberty Due to a Unique Translocation of an Abnormal Duplicated Y-Chromosome to a Deleted Chromosome 9 Including the DMRT1 Gene

Graf Stefanie , Aliu Nijas , Zeino Mazen , Flueck Christa E.

Background: Virilization at puberty in girls remains a challenge. Several differential diagnoses must be considered including disorders of sex development (DSD) and tumors.Case Report: We report an 11.5-year-old girl who was referred to our center for progressive cliteromegaly since 6 months. Past medical history was remarkable for prematurity of 36 weeks gestation and for mild ongoing psychomotor delay. At presentation ...

Contraceptives in Female Adolescents with 21-hydroxylase Deficiency (CAH) - a way to Optimize Treatment with Respect to Androgen Excess? A Pilot Study

Boettcher Claudia , Graf Stefanie , Flück Christa E

Background: At present, treatment of „classic" congenital adrenal hyperplasia (21-hydroxylase-deficiency, 21OHD) consists of glucocorticoid and mineralocorticoid replacement. However, often androgen excess and its negative metabolic impact are difficult to control without accepting glucocorticoid overtreatment, especially in adolescence. In healthy subjects oral contraceptives (containing ethinylestradiol) increase cortisol binding capacity and free c...

Urinary Vitamin E Metabolites as a Biomarker of Oxidative Stress in Type 1 Diabetes

Bulwer Chloe , Hindmarsh Peter , Pope Simon , Tollerfield Sally , Sirka Ernestas , Mills Kevin

Background: Oxidative stress has been implicated in the development and progression of complications in type 1 diabetes (T1DM). Vitamin E (α-tocopherol) undergoes β-oxidation of its chomanol ring and the resulting metabolite α-TLHQ has been proposed as a potential biomarker of oxidative stress. HbA1c relates in T1DM to microvascular complications predominantly although the end-points are late in disease development. The oxidative stress process may act independe...

Background: Steroidogenic Factor 1 (NR5A1/SF-1) is essential for the development and function of human sex and steroid organs. Variants of SF-1 lead to a broad spectrum of phenotypes including adrenal insufficiency and differences of sex development (DSD), but data on the whole picture of phenotypes in individuals with SF-1 variants are currently lacking. We aim to investigate the phenotype of individuals with SF-1 variants in a large interna...

Level of Glycemic Control in Pediatric Patients with Type 1 Diabetes in Bern: A Cross-Sectional Study

Ch. Zingg Tanja , Dennig Michelle , Sommer Grit , Flück Christa E.

Background: Good glycemic control prevents long-term complications of microvascular and macrovascular diseases in type 1 diabetes (T1DM).We aimed to investigate whether our patients had A1c values <7.5% as recommended by ISPAD and how therapy modality, duration of diabetes and pubertal status affected the metabolic control of our patients. We also set out to compare our quality of care with our results of 2008 and with other publ...
