Atypical Prednisone-Metabolism: Pharmacological Studies in a Boy with Classical Adrenal Hyperplasia and Suspected Malcompliance

Hess Melanie , Derungs Adrian , Zumsteg Urs W , Szinnai Gabor

Background: We present a boy with classical adrenal hyperplasia (CAH) and constantly increased 17-OH-progesterone (17-OH-P) values despite multiple dose adjustments of hydrocortisone up to 18 mg/m2 body surface and addition of fludrocortisone. After puberty, therapy was changed from hydrocortisone to prednisone without improvement of the 17-OH-P values. Non-compliance was suspected as cause of the inadequately controlled CAH. Alternatively, an atypical steroid metab...

Frequent and Prolonged Daytime Hypoglycemia in Diabetic Children Detected by Continuous Glucose Monitoring: A Problem of Hypoglycaemia Unawareness?

Bachmann Sara , Metzger Kerstin , Hess Melanie , Zumsteg Urs

Background: Hypoglycaemia represents a common issue in diabetic children, and the achievement of good metabolic control together with the avoidance of hypoglycemia remains a tightrope walk. As hypoglycaemia is not always recognised, data about hypoglycemia frequency are limited.Aims: We previously reported about nocturnal hypoglycaemia in diabetic children. This study now focusses on the frequency and duration of hypoglycemia at daytime and risk factors ...

Nocturnal Hypoglycaemia in Diabetic Children: Continuous Glucose Monitoring Reveals More of the Iceberg

Bachmann Sara , Martin Eva , Ritschard Vreni , Hess Melanie , Jockers Katharina , Vuissoz Jean-Marc , Zumsteg Urs

Background: Hypoglycaemia is the most common and threatening complication in diabetic children. Nocturnal hypoglycaemia is mostly unrecognised and asymptomatic, but recurrent mild hypoglycaemia at night can lead to hypoglycaemia unawareness and reduced performance at daytime.Aims: To evaluate frequency and duration of nocturnal hypoglycaemia in type 1 diabetic children and to identify risk factors for such events.Patients/methods: ...

What do they eat? Calculation of carbohydrate, fat and protein intake in children with type 1 diabetes (T1D) by use of an image based analysis by smartphone.

Bachmann Sara , Steiner Gioia , Claude Fabien , Hess Melanie , Szinnai Gabor , Burckhardt Marie-Anne

Background: Carbohydrate counting is essential in diabetes management to match insulin doses to carbohydrate intake. Though recommendations concerning macronutritient composition exist (ISPAD Clinical Practice Consensus Guidelines 2022: Nutritional management in children and adolescents with diabetes), fat and protein intake is usually not calculated. Therefore, little is known if these recommendations are followed. Lower carbohydrate intake is reported to be ...

Copeptin Kinetics and its Relationship to Osmolality During Rehydration for Diabetic Ketoacidosis in Children: An Observational Study

Burckhardt Marie-Anne , Beglinger Svetlana , Gotta Verena , Renggli Luzia , Bachmann Sara , Hess Melanie , Rentsch Katharina , Koch Gilbert , Zumsteg Urs , Jones Timothy , Pfister Marc , Szinnai Gabor

Background: Copeptin is a surrogate marker for arginine vasopressin (AVP) release in response to hyperosmolal stimuli such as diabetic ketoacidosis (DKA). We aimed to characterize the temporal course (kinetics) of serum osmolality and copeptin during rehydration and insulin therapy in children with type 1 diabetes (T1D) and DKA, and the relationship between both (dynamics).Methods: An observational multi-center study was...

Longitudinal Metabolic Control After Initiation of Insulin Pump in 5,040 Pediatric Type-1-Diabetes Subjects – Heterogeneous HbA1c Trajectories Over Three Years from the DPV Registry

Prinz Nicole , Schwandt Anke , Becker Marianne , Biester Torben , Hess Melanie , Holder Martin , Karges Beate , Näke Andrea , von Sengbusch Simone , Tauschmann Martin , Holl Reinhard W.

Objectives: Continuous subcutaneous insulin infusion (CSII) has been associated with lower HbA1c. To explore whether CSII initiation leads to HbA1c improvement in each individual with type-1 diabetes and to identify co-variates which might influence change in HbA1c.Methods: 5,040 pediatric type-1-diabetes subjects (δ20 y, 49% boys, median age at diabetes onset [Q1;Q3]: 5.9 [3.5;8.4] years) ...

Introduction: Since 2000 understanding of biology of sex development increased tremendously thanks to genetic research. This lead to new classification for persons with disorders/differences of sex development (DSD) based on genetics, and guidelines from the UK recommend revising medical care for persons with DSD by setting up interdisciplinary DSD teams. In Switzerland, persons with DSD asked for better care, stimulating the Swiss National Ethics Commission in 2012 to recomme...

Aldosterone and pro-atrial natriuretic peptide kinetics in response to rehydration in children with diabetic ketoacidosis

Burckhardt Marie-Anne , Otto Marije , Gotta Verena , Beglinger Svetlana , Bachmann Sara , Hess Melanie , Rentsch Katharina , Koch Gilbert , Davis Elizabeth , Zumsteg Urs , Jones Tim , Pfister Marc , Szinnai Gabor ,

Background: Diabetic ketoacidosis (DKA), a frequent complication of type 1 diabetes (T1D), is characterized by hyperosmolar hypovolemia. The response of water-regulating hormones to DKA treatment in children is not well known. While arginine vasopressin (AVP) is thought to respond to changes in osmolality, aldosterone and atrial natriuretic peptide (ANP) are expected to respond to volume changes (dehydration and overhydration, respectively). The objective of t...

Objective: This feasibility study aimed to investigate the anabolic effect of insulin on metabolites captured in exhaled breath during acute diabetic ketoacidosis (DKA) for a better pathophysiological understanding.Research Design and Methods: Children and adolescents with type 1 diabetes (T1D) with DKA (n=5) and without DKA (n=7) and children with epilepsy without ketogenic diet (n=18) were re...
