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...

Targetting the Binding of ACTH to the Melanocortin Receptor by Structure Modeling and Design of Peptide antagonists to Block Excess Androgens in 21-hydroxylase Deficiency

Parween Shaheena , Fluck Christa E , Pandey Amit V

Background: The adrenocorticotropic hormone (ACTH) is a 39 amino acid polypeptide secreted by the anterior pituitary and regulates cortisol secretion from the adrenal cortex. Cortisol has negative feedback and regulates the synthesis and secretion of the ACTH. Excess ACTH is associated with a wide range of diseases including congenital adrenal hyperplasia (CAH). Classic CAH due to the 21-hydroxylase (CYP21A2) deficiency causes a reduction or loss of cortisol synthesis. Here th...

Two Different Variants of Short Stature Homeobox-Containing Gene (SHOX) Mutation in the Same Family

Graf Stefanie , Santi Maristella , Losekoot Monique , Fluck Christa E.

Objectives: Deficiency of the short stature homeobox-containing (SHOX) gene is a potential etiology of short stature in children. The phenotypic spectrum of SHOX deficiency disorders, caused by haploinsufficiency of the SHOX-gene and inherited in a pseudo-autosomal dominant manner, is highly variable, even within the same family, ranging from nonspecific short stature to Leri-Weill dyschondrosteosis (LWD). Short stature, mesomelia and Madelung deformity define the classic clin...

HIV Drugs as a Possible Cause for Transient 21-Hydroxylase Deficiency in a Preterm Infant

Haamberg Tanja , Bullo Marina , McDougall Jane , Fluck Christa E.

Background: Transient neonatal adrenal dysfunction is reported in association with antiretroviral therapy with Lopinavir and Ritonavir. Other drugs have not been tested.Objective and hypotheses: We report on a preterm girl, born 26 weeks gestation, with elevated 17-hydroxyprogesterone (17OHP) at newborn screening. During pregnancy the mother was treated for HIV with Atripla (Efavirenz, Tenofovir, Emtricitabin) and viral load was suppressed. Furthermore t...

Clinical, Biochemical, Structural and Functional Characterization of a Novel P450 Oxidoreductase Mutation Causing Virilization in a 46,XX Patient

Camats Nuria , Benito-Sanz Sara , Parween Shaheena , Lopez-Siguero Juan-Pedro , Fernandez-Cancio Monica , Fluck Christa E , Udhane Sameer S , Kagawa Norio , Audi Laura , Pandey Amit V

Background: Cytochrome P450 oxidoreductase (POR) deficiency (PORD) is a form of congenital adrenal hyperplasia (CAH) and results in steroid-production loss from cytochrome P450 proteins. Mutations in POR cause mild to severe forms of CAH with/without bone malformation symptoms resembling Antley-Bixler syndrome. We report a novel POR Arg550Trp mutation identified in a 46,XX patient with signs of aromatase (ARO) deficiency. Child (first pregnancy) and mother pr...

Butyrate Stimulates GH Secretion From Rat Anterior Pituitary Cells Via the G-Protein-Coupled Receptors GPR41 and 43

Miletta Maria Consolata , Petkovic Vibor , Eble Andree , Ammann Roland , Fluck Christa E , Mullis Primus E

Background: Butyrate is a short-chain fatty acid closely related to the ketone body β-hydroxybutyrate (BHB) considered as the major source of energy during prolonged exercise. During fasting, when the liver switches to fatty acid oxidation, a rise in serum GH occurs concomitantly with the accumulation of BHB and short chain fatty acids (SCFA) acetate, propionate and butyrate. Interactions between GH, ketone body and SCFA during the metabolic adaptation to fasting are poor...

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...

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...
