Stimulated copeptin based diagnosis of central diabetes insipidus in children and adolescents

Gippert Sebastian , Choukair Daniela , Brune Maik , Bettendorf Markus

Introduction: Diagnosis of central diabetes insipidus (CDI) remains challenging. Water deprivation test and hypertonic saline infusion, as established diagnostic tests, are mentally and physically demanding for patients. Copeptin response to arginine-stimulation and insulin tolerance test (ITT) has been shown to be a putative parameter in the diagnosis of CDI in adults, but data are lacking for children and adolescents.Methods:</...

Insulin-induced copeptin response in children and adolescents to diagnose arginine vasopressin deficiency* (*partly presented at the 61st Annual ESPE Meeting 2023)

Gippert Sebastian , Brune Maik , Choukair Daniela , Bettendorf Markus

Introduction: The diagnosis of arginine vasopressin deficiency (AVD, formerly central diabetes insipidus) remains a challenge. Timely and accurate differentiation between AVD and primary polydipsia (PP) is pivotal for effective management. In recent years, stimulated copeptin has emerged as a promising tool to diagnose AVD.Methods: In this single centre retrospective study, we identified paediatric patients with suspecte...

Longitudinal assessment of bone health index (BHI) as a measure of bone health in short-statured children before and during treatment with recombinant growth hormone

Holzapfel Lukas , Bettendorf Markus , Rabe Michael , Mittnacht Janna , Choukair Daniela , Schenk Jens-Peter

Introduction: Bone Health Index (BHI) determined by measurement of cortical thickness of metacarpalia II-IV in x-rays of the left hand represents a method to estimate bone health in children. Aim of this study was to investigate changes of BHI SDS in the course of growth hormone (GH) treatment.Method: 256 consecutive children with short stature (isolated GH deficiency (IGHD) n = 121, multiple pituitary hormone deficiency...

De Novo Formation of Neutralizing IGF-I Antibodies During rhIGF-1 Treatment in a Girl with IGFALS Deficiency as Distinct Adverse Event Interfering with Growth Promotion

Mittnacht Janna , Breil Thomas , Choukair Daniela , Duffert Christin , Hwa Vivian , Rosenfeld Ron , Bettendorf Markus

Background: IGFALS deficiency is a rare cause of GH insensitivity (GHI). We report a German girl with short stature who was born as 2nd child at 40 weeks of gestation. Her Caucasian parents were unrelated and healthy (target height 168 cm, SDS 0.2). She was born appropriately sized for gestational age (49 cm, SDS -1.2; 2950 g, SDS-1.2). Height (104.8 cm; SDS -2.94) and height velocity (5.1 cm / year; SDS -1.67) were reduced at the age of 6 years.</p...

Pseudo-Precocious Puberty in Children Triggered by Incidental Transdermal Contamination with Topical Sex Steroids Through Parents

Yakovenko Vira , Choukair Daniela , Duffert Christin , Mittnacht Jana , Klose Daniela , Bettendorf Markus

Introduction: Pseudo-precocious puberty may be triggered by either endogenous or exogenous sex steroids. Accidental ingestion of contraceptives, anabolic steroids or life style products containing sex steroids as well as transdermal transmission of topical sex steroids may cause early onset of secondary sexual development.Objective: To report the clinical course of incidental contamination with topical sex steroids in ch...

Two likely compound heterozygous variants in SLC34A1 causing idiopathic infantile hypercalcemia (IIH) type 2 - a case report

Maria Duffert Christin , Choukair Daniela , Syrbe Steffen , Henje Driedger Jan , Platzer Konrad , Bettendorf Markus

Children affected by idiopathic infantile hypercalcemia (IIH) may develop polyuria, polydipsia, failure to thrive, developmental delay and nephrocalcinosis already during the first weeks of life. Elevated levels of activated 1-,25(OH)2D3 have been shown to cause the characteristic increase in serum calcium levels in this disorder. Two major underlying genetic causes have been identified so far: in IIH type 1 loss-of-function mutations in CYP24A1 ...

Pituitary Adenomas in Children and Adolescents: A Retrospective Single-Centre Analysis

Breil Thomas , Lorz Catherine , Choukair Daniela , Mittnacht Janna , Inta Ioana , Klose Daniela , Jesser Jessica , Schulze Egbert , Bettendorf Markus

Background: Paediatric pituitary adenomas are rare and mostly benign disorders which may secrete pituitary hormones. Prolactinomas account for half of all pituitary adenomas (PROLA), followed by non-secreting adenomas (20–40%; incidentalomas), adrenocorticotropic-hormone secreting adenomas (10–30%; ACTHA) and growth-hormone-secreting adenomas (5–15%; GHA).Methods: In this single-centre retrospective analysis clinical, biochemical and radio...

Automated Greulich-Pyle Bone Age Determinations in Children with Chronic Endocrine Diseases

Choukair Daniela , Huckmann Annette , Mittnacht Janna , Inta Ioana , Klose Daniela , Schenk Jens Peter , Bettendorf Markus , Thodberg Hans Henrik

Background: Prediction of adult height is a standard procedure in pediatric endocrinology, but it is associated with considerable interrater variability.Objective and hypotheses: To compare the new adult height prediction (PAH) method by automated bone age determination (BoneXpert™) with the conventional PAH method by Bayley Pinneau (BP) based on bone age determination according to Greulich & Pyle. Furthermore, to assess measures of bone health ...

Background: Congenital hypothyroidism (CH) is the most common endocrine disorder in neonates and is predominantly caused by developmental abnormalities known as thyroid dysgenesis (TD). Several transcription factors have been described in its aetiology, but defects in the known genes only account for a small proportion of cases.Methods: To identify novel genes involved in TD, we performed exome sequencing in 7 unrelated ...
