Objectives: HPP is a multisystem disorder caused by ALPL variants that lead to ALP deficiency and excessive inorganic pyrophosphate, which inhibits mineralization of bones and teeth. A range of symptoms is associated with HPP inherited in an autosomal dominant manner that can manifest at any stage of life, making diagnosis difficult. The traditional method of classifying HPP into different types based on the onset of symptoms (prenatal benign, perinat...

Background: Hashimoto’s thyroiditis (HT) is an autoimmune-mediated disorder, and is the most common cause of thyroid disease and acquired hypothyroidism in children and adolescents. In adults with HT, concentration problems, memory disorders and an increased rate of depression have been reported.Objective and hypotheses: To investigate, whether children and adolescents with HT have more behaviour and emotional problems, and/or lower intelligence tha...

Glucocorticoids are important regulators of systemic homeostasis. However, the role of these steroid hormones has been mainly studied by using synthetic glucocorticoids or in states of glucocorticoid excess. Thus, the pathophysiologic consequences of cortisol deficiency on metabolic and biosynthesis pathways remain largely elusive. Zebrafish is a well-established vertebrate model for studying whole organism biology. Similar to humans, zebrafish are day active and the key gluco...

Background: Steroid responsive encephalopathy with autoimmune thyroiditis (SREAT) is a clinically and electrographically heterogeneous steroid-responsive encephalopathy associated with thyroid autoantibodies.Objective and hypotheses: To investigate, whether children and adolescents with Hashimoto’s Thyroiditis (HT) lacking acute clinical manifestation of SREAT show electroencephalogram (EEG) alterations, and to compare EEGs of HT patients with those...

Aim: To examine the prevalence of endocrine abnormalities and outcome in children and adolescents with Anorexia nervosa (AN).Methods: The study cohort consisted of 181 patients (age 14.6±1.9 years; 160 girls, 21 boys) with AN (n=137), atypical AN (n=6) and other eating disorders except of Bulimia (n=38) who were hospitalized between Jan 2010 and Feb 2013. Somatometric [body-mass-index (BMI), BMI-SDS] and endocrine parameters were a...

Introduction: Children with hypothalamic dysfunction, e.g. due to a genetic or acquired cause such as suprasellar tumours, often suffer from hyperphagia and/or decreased resting energy expenditure (REE). This process induces uncontrollable weight gain, resulting in severe hypothalamic obesity (HO). No effective treatment is available yet for HO. Amphetamines are psychostimulants that are known for their appetite reducing and REE stimulating side effects. Here,...

Background: A broad spectrum of human diseases, including abnormalities in steroidogenesis, are caused by mutations in the NADPH cytochrome P450 oxidoreductase (POR) (1-2). Cytochrome P450 proteins perform several reactions, including metabolism of steroids, drugs and other xenobiotics. Therefore, genetic variations in POR can impact many different metabolic pathways by changing the activities of cytochromes P450 (1). In 2004 the first human patients with defe...

A broad spectrum of human diseases, including abnormalities in steroidogenesis, are caused by mutations in the NADPH cytochrome P450 oxidoreductase (POR) (1-4). Human POR is a diflavin reductase that transfers electrons from NADPH to small molecules, non-P450 redox partners and cytochrome P450 proteins in the endoplasmic reticulum. Cytochrome P450 proteins perform a very wide range of reactions, including metabolism of steroids, drugs and other xenobiotics. Therefore, genetic ...
