Glucocorticoid Deficiency Causes Differentially Dysregulated Oxidative Stress Depending on the Steroidogenic Defects

Li Nan , Weger Meltem , Griffin Aliesha , Eachus Helen , Cunliffe Vincent T , Krone Nils

Glucocorticoids regulate a wide range of biological processes including metabolism. Patients with adrenal insufficiency show impaired glucocorticoid biosynthesis either caused by adrenal defects (primary adrenal insufficiency) or by defects in the pituitary gland or hypothalamus (secondary or tertiary adrenal insufficiency). The systemic consequences of differentially disrupted steroid hormone biosynthesis remain unclear. Increasing evidence suggested steroid hormone precursor...

Glucocorticoid Deficiency Due to Disruption of Mitochondrial Steroidogenesis Leads to Dysregulation of Antioxidant Pathways and Nucleotide Biosynthesis

Weger Meltem , Gorling Benjamin , Poschet Gernot , Griffin Aliesha , Hell Rudiger , Luy Burkhard , Muller Ferenc , Krone Nils

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...

Prevalence of Idiopathic Intracranial Hypertension and Related Factors in Obese Children and Adolescents

Tepe Derya , Demirel Fatma , Seker Esra Dag , Tayfun Meltem , Esen Ihsan , Kara Ozlem , Arhan Ebru Petek

Background: Idiopathic intracranial hypertension (IIH) is a disorder of elevated intracranial pressure without any evidence of intracranial pathology or underlying systemic disease. Obesity was reported as a significant cause of IIH in childhood especially in adolescents.Objective and hypotheses: IIH is a disorder of elevated intracranial pressure without any evidence of intracranial pathology or underlying systemic disease. Obesity was reported as a sig...

Complete Blood Count Parameters in Girls with Polycystic Ovary Syndrome

Ucakturk Ahmet , Demirel Fatma , Tayfun Meltem , Tepe Derya , Elmaogullari Selin , Kara Ozlem

Background: Polycystic ovary syndrome (PCOS) is characterized by ovulatory dysfunction and excess androgen secretion. Androgens may affect bone marrow cells via androgen receptor which expressed in the bone marrow. Also it is known that especially testosterone increases hemoglobin and hematocrit concentrations.Objective and hypotheses: Our aim in this study is to describe the relation between hyperandrogenism and complete blood count (CBC) parameters in ...

Glucose 6 phosphate dehydrogenase deficiency diagnosed with hemolytic anemia triggered by diabetes mellitus type 1

Orman Burce , Cetinkaya Semra , Oner Nergis , Akcaboy Meltem , Fettah Ali , Guleray Lafcı Naz , Erdeve Senay Savas ,

Background: Glucose 6 phosphate dehydrogenase (G6PD) is expressed in all tissues and is necessary for the oxidant stress capacity of cells. G6PD deficiency is the most common enzymopathy in humans; it is among the important causes of hemolytic anemia. It has been reported that severe hemolytic anemia due to G6PD deficiency may develop in newly diagnosed diabetes, especially during the correction of hyperglycemia. To date, 9 cases have been described in the lit...

The Use of Pamidronate in Pediatric Patients with Disease of Other than Osteogenesis Imperfecta: the Experience of Our Center

Guven Ayla , Helvacioglu Didem , Hancili Suna , Yildiz Metin

Background: Bisphosphonate treatment for bone fragility has expanded beyond the children with osteogenesis imperfecta (OI) to those with other causes of low bone mass. Pamidronate is effective such as Paget’s disease, hypercalcaemia of malignancy, osteolytic bone metastasis, steroid-induced osteoporosis and idiopathic osteoporosis.Objective and hypotheses: The experience with bisphosphonates treatment other than OI in children is limited although th...

Adrenal Atrophy Secondary to Inappropriate Oral Administration of Exogenous Steroid Presenting with Hypercalcaemia

Guven Ayla , Kilinc Suna , Helvacioglu Didem , Kuru L ihsan

Background: Glucocorticoids are one of the most widely used drugs in clinical practice. Inappropriate use can result in secondary adrenal insufficiency. Adrenal insufficiency can be an occult cause of hypercalcaemia.Case presentation: A 3-months-old boy admitted for puffiness of the face, increase in weight. It was revealed that the patient was admitted to a hospital 2 months ago and was diagnosed to have congenital cataract and operated. The patient was...

A Novel Animal Model to Study 21-Hydroxylase Deficiency in vivo

Zaucker Andreas , Griffin Aliesha , Storbeck Karl-Heinz , Guran Tulay , Thakur Nazia , Weger Meltem , Taylor Angela , Mueller Ferenc , Krone Nils

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is caused by mutations in the CYP21A2 gene. Steroid 21-hydroxylase deficiency results in impaired synthesis of mineralcorticoids and glucocorticoids (GC), plus androgen excess. Hormonal imbalances in 21OHD are postulated to result in systemic transcriptomic and metabolomic alterations. Such perturbations are likely to be underlying co-morbidities, which are increasingly observed in individua...

A Novel Glucokinase Gen Mutation: Mody Type-2 Case

Arasli Yilmaz Aslihan , Elmaogullari Selin , Demirel Fatma , Tayfun Meltem , Ahmet Ucakturk Seyit , Gurbuz Fatih , Kemal Topaloglu Ali

Background: Maturity-Onset Diabetes of the Young (MODY) is a rare monogenic form of diabetes that result in β-cell dysfunction. MODY accounts for 2–5% of all diabetes cases. We presented here a family with MODY2 caused by a novel heterozygous p.L164I (c.490 C>A) mutation of the GCK gene.Case: A 15,5-year-old girl was admitted to our department because of fasting hyperglycemia. She had no polyuria, polydipsia and weight loss...

Macro TSH- a Rare Cause of High Levels of TSH

Elmaogullari Selin , Yilmaz Aslihan Arasli , Ucakturk Seyit Ahmet , Tayfun Meltem , Gurbuz Fatih , Ucar Fatma , Bulut Erdem , Hattori Naoki , Demirel Fatma

Background: Macro TSH is a high molecule weighed complex with low bioactivity that is comprised of TSH and anti-TSH antibodies. Potentiality of macro TSH should be kept in mind in clinically euthyroid and asymptomatic patients with normal free T4 and T3 levels and relatively high TSH levels. Diagnosis of macro TSH is suspected if polyethylene glycol (PEG) precipitable TSH exceeds %75 and confirmed if high molecule weighed TSH is shown with gel filtration ...
