Diabetes type 1 can induce testicular atrophy with Leydig cell hyperplasia and germ cell depletion and therefore prevents reproductive function and fertility in rats

Viola Wagner Isabel , Kloeting Nora , Kulle Alexandra , Rieck Karen , Söder Olle , Hiort Olaf

Research Aim: Diabetes type 1 can negatively influence testicular function and fertility but the pathomechanisms on the testicular level remain to be elucidated. Therefore, the aim of the study was to evaluate effects of diabetes mellitus type 1 disease on testicular function.Material and Methods: BB/OKL rats developed type 1 diabetes during adolescence. Rats were treated with different Insulin implants to achieve suffic...

Alterations in glucocorticoid metabolism as a possible cause of hypertension in childhood obesity

Martijn JJ Finken , JG Wirix Aleid , A von Rosenstiel-Jadoul Ines , van der Voorn Bibian , JM Chinapaw Mai , F Hartmann Michaela , E Kist-van Holthe Joana , A Wudy Stefan , Rotteveel Joost

Introduction: Childhood obesity is associated with alterations in hypothalamus-pituitary-adrenal axis activity. We tested the hypothesis that multiple alterations in the metabolism of glucocorticoids are required for the development of hypertension in children who become overweight.Methods: Timed spot urine for targeted gas chromatography-mass spectrometry steroid metabolome analysis was collected from (1) overweight/hyp...

Learning from Histopathology to Design Novel Immune-Therapies for Type 1 and 2 Diabetes

von Herrath M

Study of the histopathology of human type 1 and 2 diabetes through the national pancreatic organ donor (nPOD) consortium has yielded interesting new insights that should also aid us in developing improved therapeutic approaches.1. When insulitis is observed, it usually shows a predominance of CD8 T cells, some of which are autoantigen specific (see also Coppieters et al. JEM 2012). It will be therapeutically challenging to remove/prevent CD8 mem...

De-novo and Depot-Specific Androgen Production in Human Adipose Tissue - a Source of Hyperandrogenism in Obese Females

Wagner Isabel Viola , Sahlin Lena , Kulle Alexandra , Klöting Nora , Döbeln Viola , Savchuk Iuliia , Dötsch Jörg , Söder Olle

Background: Obesity in females is often associated with metabolic complications and hyperandrogenism but the role of adipose tissue (AT) in androgen synthesis remains unclear.Aims/Objectives: Employing human subcutaneous and visceral AT and cultured adipocytes, we studied whether AT could be a source of androgens promoting hyperandrogenism in lean and especially in obese females.Methods</st...

Persistent Ketotic Hypoglycemia as an Atypical Presentation of Heterozygous HNF4A Mutation

von Oetting Julia , Mitchell John , Cloutier Daphne , Yau Daphne

Background: Heterozygous loss-of-function HNF4A mutations are known to lead to monogenic diabetes, and in infants to macrosomia and hyperinsulinemic hypoglycemia. We are reporting a patient with a heterozygous HNF4A mutation (c.997C>T p.ARG333Cys) presenting with persistent ketotic hypoglycemia.Case report: In a 38 weeks’ gestation infant (birth weight 4.1 kg, pregnancy complicated by insulin-requiring gestational diabetes), hy...

A New Lipodystrophy Syndrome?

von Schnurbein Julia , Fischer-Posovszky Pamela , Garg Abhimanyu , Wabitsch Martin

Background: Congenital generalized lipodystrophy (CGL) is characterized by the absence of most adipose tissue at birth due to an adipocyte differentiation block. For several forms of CGL, the underlying mutation and pathophysiological pathway has been identified. However, for many cases the genetic cause is still unknown.Objective and hypotheses: We report a patient with CGL who showed a complete absence of fat apart from protective fat pads in a postnat...

A retrospective analysis of children and youth with congenital adrenal hyperplasia treated with hydrocortisone modified-release hard capsules

Neumann Uta , von Mackensen Jolande , Lankes Erwin , Blankenstein Oliver

Context: Children with congenital adrenal hyperplasia (CAH) require hydrocortisone replacement from birth. The highest ACTH driven endogenous production of androgens happens in the early morning. To achieve a good therapy control, immediate release hydrocortisone is given early in the morning or late at night. In year 2021 the hydrocortisone modified-release hard capsule (Efmody®) was approved by the European medicine agency and from September 2021 it is l...

Gonadal Function in Congenital Adrenal Hyperplasia (CAH)

Claahsen - van der Grinten Hedi

Congenital adrenal hyperplasia (CAH) is a group of rare congenital disorders of the adrenal cortex due to a defect in one of the enzymes involved in steroid synthesis leading to cortisol deficiency and overproduction of adrenal androgens. In the most severe forms CAH is a life threatening disease due to the risk of Addisonian and salt wasting crisis. In the last 50 years diagnostics and treatment improved significantly. Patients are treated with lifelong replacement of glucoco...

Impact of β-cell function and glucose effectiveness on the development of type 2 diabetes mellitus in obese European children and adolescents

Ellen Kratzer Sophie , Vogt Josef , Kohlsdorf Katja , von Schnurbein Julia , Wabitsch Martin , Denzer Christian

Objectives: Despite high prevalence rates of childhood obesity, youth-onset T2DM occurs in a comparably lower incidence in Europe than in other world regions. Available data from cohorts of obese children and adolescents living in the US suggest a parallel decline of insulin sensitivity and β-cell function as key factors in the pathophysiology of early-onset T2DM. If these results can be applied to European children and adolescents is currently unknown.</...

Effects of long-term metreleptin replacement therapy on weight and comorbidities in a patient with bioinactive leptin

Zorn Stefanie , von Schnurbein Julia , Kohlsdorf Katja , Brandt Stephanie , Wabitsch Martin

Introduction: Congenital leptin deficiency can be treated with the human leptin analogon metreleptin as first reported in 1999. To date, the long-term effects (> 1 year) of metreleptin treatment on anthropometry and comorbidities have only been described in 8 patients with leptin deficiency. Here, we present the long-term effects of metreleptin substitution on weight and comorbidities in a patient with bioinactive leptin.Metho...
