A 46, XX Patient with 21-OHD Diagnosed During the Etiologic Workup of Male Infertility

Buğrul Fuat , Yildirak Ekrem , Güran Tülay

Introduction: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders of the steroid biosynthesis. 21-hydroxylase deficiency (21-OHD) represents 90–95% of CAH patients and causes adrenal insufficiency and virilization. Although most patients are diagnosed in childhood, the diagnosis of some classical CAH cases are extremely delayed up to sixth and seventh decades of life. Herein, we report a 46, XX patient with 21-OHD diagnose...

A novel heterozygous mutation in the SLC5A2 gene causing mild failure to thrive and subclinical hypoglycemia in a 2-year old girl

Dermitzaki Eleni , Manolakos Emmanouil , Filiousi Fotini , Kleanthous Kleanthis , Papadimitriou Dimitrios T.

Patients: A 2-year old girl was referred due to glucosuria 1874 mg/dl. Fasting blood sugar was 71 mg/dl and HbA1c 4.8%. Examination of her growth charts revealed mild failure to thrive, since 15 months of age, as far as weight gain and height velocity. We used Flash technology (FreeStyle Libre) to identify hypoglycemic episodes. In 9 days, 8% of the time was < 70 mg/dl, with 11 hypoglycemic events: mean duration 94 min, lowest 52 mg/dl.<p class...

The Roles of Steroids in Gonadal Development and Maintenance – Insights from a Zebrafish Model of Androgen and Cortisol Deficiency

Oakes James A. , Li Nan , Wistow Belinda , Storbeck Karl-Heinz , Cunliffe Vincent T. , Krone Nils

Increasing evidence suggests that the aetiology of disorders of sex development cannot be solely explained by genetic alterations. It is highly likely that environmental factors hitting susceptible genetic backgrounds are partly causative. Zebrafish sex is highly plastic during development, making this species an ideal model for investigation of endocrine disruption and gonadal development and function. However, the hormonal regulation of these processes in zebrafish is poorly...

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...

REplacement of MAle mini-Puberty in Neonates and Children with Micropenis and Cryptorchidism due to Hypogonadotropic Hypogonadism: Results of the ‘REMAP’ Study ISRCTN13007297

Papadimitriou Dimitrios T , Chrysis Dionysios , Nyktari Georgia , Zoupanos George , Liakou Eleni , Papadimitriou Anastasios , Mastorakos George

Background: Hormonal replacement in boys with congenital Hypogonadotrophic Hypogonadism (HH) as well as hormonal repair of bilateral cryptorchidism and micropenis remain a challenge in pediatric endocrinology.Methods: In the «REMAP» study ISRCTN13007297 eight neonates and infants, all with bilateral cryptorchidism in intra-abdominal position and micropenis (≤2 cm), with absence of neonatal male-mini puberty were treated for 3 months with ...

Can Neuroimaging Predict Endocrine Morbidity in Congenital Hypothalamo-Pituitary (H-P) Disorders?

Cerbone Manuela , Guemes Maria , Wade Angie , Improda Nicola , Dattani Mehul T

Background: Few studies have described the phenotypic spectrum of Septo-Optic Dysplasia (SOD). The aim of this study was to evaluate the range of H-P structural abnormalities and the endocrine morbidity of children with SOD and related disorders.Methods: Retrospective longitudinal single centre study of children with SOD (n:171), Multiple Pituitary Hormone Deficiency (MPHD) (n:53) and Optic Nerve Hypoplasia (ONH) (n:35).<p class="ab...

Gain in Predicted Adult Height Using the Combination of an LHRH Analogue and an Aromatase Inhibitor in Early Maturing Girls with Compromised Growth for 2 yrs or Until the Age of 11 is Maintained and Further Improved by Aromatase Inhibitor Monotherapy: Results on Final Height of the ‘GAIL’ Study ISRCTN11469487

Papadimitriou Dimitrios T , Dermitzaki Eleni , Papagianni Maria , Kleanthous Kleanthis , Attilakos Achilleas , Mastorakos George , Papadimitriou Anastasios

Background: Third generation aromatase inhibitors (AI) have never been used as monotherapy to increase predicted adult height (PAH) in girls. Our previously published GAIL study (J Endocrinol Invest. 2016 Apr;39(4):439–46) has shown that the combination of anastrozole to an LHRH analogue for 24 months is safe and effective in ameliorating PAH in girls with early puberty +1.21 SDS (+7.51 cm) compared to inhibition of puberty alone +0.31 SDS (+1.92 cm), P=...

A 13 Year-Old Boy Diagnosed as Osteogenesis Omperfecta with Normal Bone Mineral Density

Tınastepe Tuba , Filibeli Berna Eroğlu , Catlı Gonul , Dundar Bumin Nuri

Osteogenesis imperfecta is a hereditary connective tissue disease developing based on the structure or synthesis impairment of type 1 collagen and proceeding with diffuse osteoporosis, fragility, fractures and deformities in bones. Bone mineral density can be at normal or even high levels particularly especially in type I and XIII. Here, a 13 year-old boy diagnosed as osteogenesis imperfecta with normal bone mineral density was presented and treatment results were shared. A 13...

Effect of a Melanocortin-4 Receptor (MC4R) Agonist, Setmelanotide, on Obesity and Hyperphagia in Individuals Affected by Alström Syndrome

Han Joan C , Fiedorek Fred T , Hylan Michelle , Folster Cathy , Hiwot Tarekegn

Background: Alström syndrome (AS) is a rare genetic ciliopathy characterized by severe early-onset obesity, hyperphagia, retinal dystrophy, hearing loss, and cardiomyopathy. Rodent studies suggest that cilia play an important role in the leptin-MC4R pathway, which regulates energy balance and body weight. Setmelanotide, a peptide agonist of the MC4R, has led to weight loss in individuals affected by other rare genetic obesity disorders resulting from dysfunction in this p...
