Prepubertal Children Born Large for Gestational Age have Lower Serum DHEAS Concentrations than those with Lower Birth Weight

Nordman Henrikki , Voutilainen Raimo , Jaaskelainen Jarmo

Background: In some studies, prepubertal children born small for gestational age (SGA) have had a higher prevalence of premature pubarche and higher serum DHEAS concentrations than children born appropriate for gestational age (AGA). The overall metabolic risk associated with birth weight is U-shaped, but it is not known if children born large for gestational age (LGA) have elevated serum DHEAS levels.Objective and hypotheses: The aim of this study was t...

Introduction: Turner syndrome (TS) is a genetic condition which is reported to be associated with electrocardiogram (ECG) abnormalities, of which the rate-corrected QT interval (QTc) is the most common indicated deviation. Our objectives were to gain more insight in the prevalence of QTc-prolongation using both Bazett's and Hodge's correction formulas in patients with TS of all ages and to investigate whether QTc prolongation is more prevalent in patie...

An Unusual Cause of Primary Amenorrhoea Suggested by the Urine Steroid Profile

Fuentes-Bolanos Noemi Auxiliadora , Taylor Norman , Wei Christina

Background: The optimal timing and appropriate first-line investigations for delayed menarche in an otherwise well teenager with fully developed secondary sexual characteristics is debatable.Case presentation: A 15 year-old female presented with parental concerns of cliteromegaly. Facial acne and primary amenorrhoea were also noted. Pubic hair development started at age 10 years and breast development age 12 years. Family history revealed delayed menarch...

Role of PTEN in the Proliferation and Differentiation of Preadipocytes

Kirstein Anna , Kassner Franziska , Schmid Gordian L. , Handel Norman , Penke Melanie , Kiess Wieland , Garten Antje

Background/aim: The PTEN hamartoma tumor syndrome (PHTS) is an overgrowth syndrome caused mainly by germline mutations in the tumor suppressor PTEN. Patients are predisposed for the development of malignant and benign tumors. Children and adolescents with PHTS frequently develop single or multiple lipomas. PTEN antagonizes the phosphatidylinositide3-kinase/AKT/mechanistic target of rapamycin (PI3K/AKT/mTOR) pathway, which promotes proliferation and differentiation in ...

Resveratrol Potentiates Growth Inhibitory Effects of Rapamycin in PTEN-deficient Lipoma Cells by Suppressing p70S6 Kinase Activity

Leipert Jenny , Kassner Franziska , Schuster Susanne , Handel Norman , Korner Antje , Kiess Wieland , Garten Antje

Background: Patients with PTEN (phosphatase and tensin homolog) hamartoma tumor syndrome and germ line mutations in PTEN frequently develop lipomatosis, for which there is no standard treatment. Rapamycin was shown to reduce the growth of lipoma cells with heterozygous PTEN deficiency in vitro, but concomitantly induced an up regulation of AKT phosphorylation.Objective and hypotheses: Since it was shown that resveratrol stabilizes PTEN,...

Background: We present a patient with co-existence of two rare conditions 3β-Hydroxysteroid dehydrogenase type 2 deficiency (HSD3B2) the rarest form of Congenital Adrenal Hyperplasia (CAH) and Bartter’s Syndrome (hypokalaemic alkalosis secondary to hyperaldosteronism).Case Report: A female infant (46XX) born at 34/40 weeks weighing 2.67 kg to non-consanguineous parents presented on day four of life with significant weight loss. Subsequent inves...

The Impact of Activating PIK3CA Mutations and PTEN Haploinsufficiency on Human Adipocyte Phenotype and Biology

Kassner Franziska , Handel Norman , Leipert Jenny , Sauer Tina , Wilhelm Franziska , Landgraf Kathrin , Kiess Wieland , Korner Antje , Garten Antje

Background: The phosphatase and tensin homolog (PTEN)/phosphatidylinositol-3-kinase (PI3K)/AKT signaling pathway is central for cell cycle control, differentiation, migration, and metabolism. Unrestricted growth of adipose tissue in particular is frequently seen in humans with germline PTEN and mosaic activating PIK3CA mutations, respectively.Objective and hypotheses: We assume that adipocytes from affected tissue show hyperproliferation and modified dif...

Re-appraising the use of urinary steroid profiles for assessing therapy control in children with 21-hydroxylase deficiency – results from the CAH-UK cohort study

Introduction: Patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) have specific plasma and urinary steroid patterns, with 11-oxygenatedC19 steroids established as key adrenal-specific androgens. Monitoring glucocorticoid (GC) replacement remains a challenge in the absence of reliable biomarkers.Aim: To reassess the urinary steroid profile of children with CAH in relation to plasma ...
