A Novel AIRE Gene Mutation in Two Siblings Revealing Different Phenotypes of Autoimmune Polyendocrine Syndrome Type 1

Yildiz Melek , Aydin Banu , Gezdirici Alper , Onal Hasan

Background: Autoimmune polyendocrine syndrome type 1 (APS-1) is a rare autoimmune disease characterized by chronic mucocutaneous candidiasis, hypoparathyroidism and primary adrenal insufficiency. Minor components of the disease are diverse among patients, even within the same family. APS-1 is autosomal recessively inherited and caused by biallelic mutations in the autoimmune regulator (AIRE) gene.Objective and Hypotheses...

Deep subcutaneous adipose tissue is associated with hyperinsulinemia in adolescents

Cerenius Sara Y. , Stenlid Rasmus , Aydin Banu , Weghuber Daniel , Bergsten Peter , Forslund Anders

Introduction: Abdominal subcutaneous adipose tissue (SAT) is subdivided into two depots by the fascia of Scarpa. The deep SAT (dSAT) and superficial SAT (sSAT) are morphologically and metabolically distinct, with dSAT reportedly being more similar to visceral adipose tissue (VAT) in terms of elevating the risk for obesity-related complications. Conversely, sSAT appears to be more similar to lower-body SAT. The relationship between dSAT and metabolic disease ha...

Children with Hashimoto's Thyroiditis have Increased Intestinal Permeability: Results of a Pilot Study

Aydin Banu Kucukemre , Yildiz Melek , Akgun Abdurrahman , Dogan Beyza Belde , Topal Neval , Onal Hasan

Background: Both genetic and environmental factors serve as the trigger of Hashimoto's thyroiditis (HT), but the exact mechanisms are still not fully understood. Increased intestinal permeability was shown to be a constant and early feature of several autoimmune disorders. Although HT is the most common autoimmune disorder worldwide, the role of intestinal permeability in its pathogenesis had received little attention. Human zonulin modulates intracellular...

The follicle-stimulating hormone receptor is expressed in human pancreatic islet beta-cells and its activation increases glucose stimulated insulin secretion

Background: Follicle-stimulating hormone (FSH) plays a key role in reproduction. The G-protein coupled FSH receptor (FSHR), is expressed primarily in gonads, and specifically binds FSH. FSHR is also expressed in vascular endothelium, osteoclasts, adipose tissue, monocytes and rodent pancreatic islets. Elevated FSH levels are associated with development of obesity, insulin resistance, osteoporosis, and cardiovascular disease. In a recent study, we showed that h...

Six-months of treatment with exenatide improves glycemic control, but does not affect endogenous intact GLP-1 concentrations in adolescents with obesity

Stenlid Rasmus , Y. Cerenius Sara , K. Aydin Banu , S. Gjessing Erik , Manell Hannes , Weghuber Daniel , Forslund Anders , Bergsten Peter

Introduction: When used to treat obesity, glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RA) improve both BMI and metabolic health. Liraglutide is approved by both the EMA and FDA for the treatment of pediatric obesity, from 12 years and older. However, 26 weeks after discontinuation of liraglutide, the weight lost during treatment is regained. Prolonged exogenous stimulation of hormone-specific receptors may influence endogenous hormonal regulation. ...

Frequency of Enzyme Deficiencies in a Turkish Cohort of Congenital Adrenal Hyperplasia: A Single-Center Experience with 145 Patients

Yildiz Melek , Onal Hasan , Aydin Banu , Akgun Abdurrahman , Dogan Beyza Belde , Topal Neval , Akcay Teoman , Adal Erdal

Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder caused by a defect in any of the enzymatic steps of adrenal steroidogenesis. It occurs due to mutations in genes that encode enzymes involved in the synthesis of cortisol from cholesterol. The most common cause is 21-hydroxylase deficiency, with 11-beta hydroxylase, 3-beta hydroxysteroid dehydrogenase, 17-alpha hydroxylase and POR deficiency being among rarer causes.Objec...

Introduction: Rate of weight gain during early childhood may have an effect on timing of puberty in girls. Biological mechanisms underlying this condition are not fully understood. Studies examining this association in boys report contradictory results. Our aim was to examine the effects of growth rate during the first years of life on the onset of puberty both in girls and boys.Description of methods: 159 children aged between 6 and 9 years who were att...

Adrenal Rest Tumors in Patients with Primary Adrenal Insufficiency

Background: Gonads containing adrenal rests may enlarge in response to chronic overstimulation by ACTH in diseases with ACTH hypersecretion such as poorly controlled congenital adrenal hyperplasia (CAH), Addison’s disease and Nelson’s syndrome. Testicular adrenal rest tumors (TART) are present in childhood in CAH patients and frequency in adults may be up to 50–95%. Ovarian adrenal rest tumors (ART) are less frequently detected. TART is decribed less in patients...

Background: Nonclassical congenital adrenal hyperplasia (NCAH), which is generally presented with symptoms of androgen excess, is inherited autosomal recessive due to different kind of mutations in the CYP21A2. Recently, high frequency of copy number variations at CYP21A2 gene and predisposition of heterozygous duplicated CYP21A2 for de novo gene aberrations has been reported.Objective and hypotheses: To evaluate clini...

Background: Turner syndrome is one of the most common chromosomal disorders and is seen in 1:2500 female live births. The disease manifests with various clinical features and can be classified according to karyotype as monosomy, mosaicism, numeric, and structural abnormalities.Objective and hypotheses: Patients with Turner syndrome have complicated with various manifestations congenital or acquired. In this study we aimed to emphasise the importance of a...
