How do urine steroid metabolites of spot samples correlate with 24 hour urine specimens in children with congenital adrenal hyperplasia?

Sommer Grit , Abawi Ozair , Groessl Michael , Halbsguth Ulrike , Charmandari Evangelia , Akker Erika L.T. van den , Fluck Christa E. ,

Introduction: Steroid profiling in children with congenital adrenal hyperplasia (CAH) is used to monitor the balance between androgen and cortisol metabolites and to decide on the optimal glucocorticoid dosage. Twenty-four hour collection is the gold standard for measurement of steroid metabolites in urine, because steroid production follows a circadian rhythm and is influenced by short-term stress and steroid drugs. For some children, e.g. those who were diap...

Reference values for the insulin response to glucose challenge enable the early detection of emerging (pre)diabetes in children and young adults with obesity

Stein Robert , Vogel Mandy , Stanik Juraj , Kratzsch Jürgen , Stumvoll Michael , Blüher Matthias , Kiess Wieland , Körner Antje

Background: The course of type 2 diabetes is more severe among children with obesity than among adults. Therefore, children at high risk for glycemic deterioration should be detected early enough to guide preventive (and interventional) clinical management.Methods: We established age- and puberty-specific reference values for 7 different indexes addressing the insulin response during oral glucose tolerance testing upon 4...

Effective GH Replacement with Once-weekly Somapacitan in Japanese Children with GH Deficiency: 2-year Results from REAL4

Growth hormone deficiency (GHD) in children results in reduced adult height. Children with GHD typically require daily subcutaneous (s.c.) injections of growth hormone (GH). Daily injections are burdensome for both patients and their caregivers and reduced adherence negatively impacts clinical outcomes. Somapacitan (Novo Nordisk) is a long-acting reversible albumin-binding human GH derivative in development for once-weekly s.c. administration in children with GHD, aiming to ov...

The serum steroid signature of PCOS hints at the involvement of novel pathways for excess androgen biosynthesis

Murat Altinkilic Emre , du Toit Therina , Sakin Onder , Attar Rukset , Grössl Michael , E. Flück Christa

Context: Polycystic ovary syndrome (PCOS) is defined by androgen excess and ovarian dysfunction in the absence of a specific physiological diagnosis. The best clinical marker of androgen excess is hirsutism, while the best biochemical parameter is still a matter of debate. Current consensus guidelines recommend serum free testosterone as the most sensitive serum parameter to measure androgen excess. Recently, however, novel active androgens and androgen metabo...

Hyperparathyroidism is associated with inferior event free survival in lymphatic childhood malignancies in a single center retrospective analysis

Grasemann Corinna , Höppner Jakob , Tippelt Stephan , Grabow Desiree , Cario Gunnar , Zimmermann Martin , Reinhardt Dirk , M Schündeln Michael

Introduction: Vitamin D status is investigated as a modifier for the risk and course of multiple malignant diseases. Findings point towards a detrimental role of low vitamin D levels for event free and overall survival (EFS/OS). However, vitamin D deficiency is often associated with secondary hyperparathyroidism, which may influence EFS/OS in childhood malignancies.Methods: Real world data from 1547 cases (873 male) of c...

Augmented Fibroblast Growth Factor 21 Serum Levels in Metabolic Disorders and Association With Endothelial Function in Childhood

Domouzoglou Eleni , Vlahos Antonios , Challa Anna , Papafaklis Michail , Tsatsoulis Agathocles , Michalis Lampros , Chaliasos Nikolaos , Naka Katerina

Introduction: Obesity and the metabolic syndrome (MetS) are linked to increased risk for endothelial dysfunction which is considered as the first step in the progression of cardiovascular disease. Fibroblast growth factor 21 (FGF21) is a protein with known effects on various metabolic pathways. In adults, the circulating blood levels of FGF21 have been associated with parameters of lipid/carbohydrate metabolism, and FGF21 is known to be increased in obesity. T...

Software-assisted Analysis of the Urinary Steroid Metabolom in Treated Children with Classic Congenital Adrenal Hyperplasia

Kamrath Clemens , Hartmann Michaela F. , Wudy Stefan A.

Background: Treatment of children with classic congenital adrenal hyperplasia (CAH) is a difficult balance between hypercortisolism and hyperandrogenism. Biochemical monitoring of treatment is not well defined.Objective: Retrospective software-assisted analysis of urinary steroid metabolome analysis obtained by gas chromatography-mass spectrometry (GC-MS) for treatment monitoring of children with CAH.<p class="abstex...

Quantitative Urinary GC–MS Based Steroid Analysis for Treatment Monitoring of Adolescents and Young Adults with Autoimmune Primary Adrenal Insufficiency

Kamrath Clemens , Hartmann Michaela F , Wudy Stefan A

Background: Autoimmune primary adrenal insufficiency (PAI) is a rare and life-threatening disease. Standard replacement therapy consists of multiple daily doses of hydrocortisone combined with fludrocortisone. A recent Endocrine Society guideline argued against hormonal monitoring of glucocorticoid replacement. However, about 50% of adolescents and young adults (AYAs) with chronic diseases are non-adherent to their prescribed treatment regimens. Pervasive nonadherence places p...

Genetics of Thyroid Dysgenesis and Associated Malformations

Polak Michel

Thyroid dysgenesis (TD) is the most common cause of congenital hypothyroidism in iodine sufficient regions. TD includes a broad spectrum of developmental anomalies varying from absence of thyroid (athyreosis) to an abnormally located thyroid (ectopy), small (hypoplasia) or asymmetric thyroid. Thyroid dysgenesis is usually sporadic, but up to 2% of cases is familial. Genetics of TD is complex and advances in developmental biology over the past two decades revealed monogenetic f...

The Pros and Cons of Using Sulfonylurea before Genetic Testing in Neonatal Diabetes Mellitus

Polak Michel

Background: Very early onset diabetes mellitus (neonatal diabetes mellitus (NDM)) seems to be unrelated to autoimmunity in most instances. A number of conditions are associated with NDM, some of which have been elucidated at the molecular level. Among these, the recently elucidated mutations in the KCNJ11 and ABCC8 genes, encoding the Kir6.2 and SUR1 subunit of the pancreatic KATP channel involved in regulation of insulin secretion, account for one...
