Establishing the Role of the Steroid Backdoor Pathway for Androgen Biosynthesis in the Human Ovary

Marti Nesa , Sauter Kay S , Mullis Primus E , Fluck Christa E

Background: Recent work revealed two pathways in androgen biosynthesis, namely the classic and an alternative, the backdoor pathway. In this alternative pathway dihydrotestosterone is produced from 17-hydroxyprogesterone without the intermediacy of testosterone using mostly enzymes that are specific to the backdoor path. In the human ovary, regulation of androgen production plays a crucial role in normal physiology and in pathologies such as the polycystic ovary syndrome (PCOS...

Does Skeletal Disproportion in Children with Idiopathic Short Stature Influence Response to GH Therapy?

Cutfield Wayne S , Lindberg Anders , Hofman Paul , Derraik Jose , Geffner Mitchell E , Camacho-Hubner Cecilia

Background: Children with ISS have an array of causes that lead to short stature and/or poor growth velocity. Genetic causes of short stature, notably SHOX mutations, can be associated with subtle skeletal disproportion with shorter limbs, manifesting as increased sitting-to-standing height ratios or SDS.Objective and hypothesis: Children with ISS and skeletal disproportions have a diminished growth response to GH treatment compared to chi...

Genetic Variation in the FSH Signalling Pathway Affects Female Reproductive Hormones During Infancy

Henriksen Louise S , Hagen Casper P , Assens Maria , Almstrup Kristian , Main Katharina M

Background: Studies have shown that genetic variations in the FSH pathway (SNPs: FSHB −211G>T, FSHR −29G>A, and FSHR 2039A>G) affect peripubertal levels of serum FSH and age at pubertal onset in girls.Objective and hypotheses: Genetic variations in the FSH pathway reflect circulating levels of female reproductive hormones during the postnatal gonadotropin surge.Method: Blood samples were taken in girls of th...

Disturbances of glucose homeostasis in polytransfused beta-thalassemia patients

Mustapha Noumi , N Khelafi , Y Ferhani , S Sokhal , R Terrak , R Boukari ,

Introduction: β-thalassemia is a hereditary chronic hemolytic anemia characterized by a defect in the synthesis of beta-globin chains, particularly common in the Mediterranean region, southern Asia, and the Middle East (1) Transfusion programs and chelating therapy have greatly extended the life expectancy of patients (2). This has led to an increase in the prevalence of endocrine complications, linked to iron overload (3) including abnormalities in gluco...

6-Month GnRHa Formulations Are a Good Choice During the COVID-19 Pandemic and Beyond

R. Benson Matthew , N. Atkinson Stuart , M. Boldt-Houle Deborah , Miller Bradley S. ,

Introduction: Achieving/maintaining effective hormone suppression is fundamental in treating Central Precocious Puberty(CPP). CPP patients are vulnerable to late dosing as they cannot self-administer and require clinic/hospital visits for injections, currently exacerbated by COVID-19. In children, the hypothalamic-pituitary-gonadal axis may rebound faster than elderly oncology patients, so hormone escapes are possible with late dosing. Additionally, the stimul...

Dose dependent risks of glucocorticoid treatment in classic CAH

Saragolou Kyriakie , Casteràs Anna , Will Charlton R , Barnes Chris , Thornton Paul

Introduction: In congenital adrenal hyperplasia (CAH), glucocorticoid (GC) treatment must perform two functions – to replace cortisol deficiency and to suppress the excess production of adrenal androgens. Unfortunately, androgen suppression usually requires supraphysiologic GC doses, which are associated with serious comorbidities. Our study examined the exposure or dose-dependent relationships between GCs and GC-related adverse events (GCRAEs) and comor...

Recombinant human growth hormone treatment for osteogenesis imperfecta: report of two cases

Eduardo Cruvinel Pinto Luís , Scheidemantel Aline , Junqueira Soares Gabriel , Ângela Ramires de Carvalho Julienne

Background: Osteogenesis imperfecta (OI) is a genetic connective tissue disorder with variable phenotype, mainly characterized by bone fragility, short stature and non-skeleton findings. Since growth failure is a predominant feature of OI, recombinant human growth hormone (rhGH) has been suggested as a potential intervention. We describe two boys with OI type I treated with rhGH.Case Reports: Patient 1 had the first frac...

Impact of bariatric surgery on obesity complications in children and adolescents: Evaluation of a large cohort within a specialized French obesity center

Mosser Camille , Dagher Ibrahim , De Filippo Gianpaolo , Thebaut Alice , Linglart Agnès , Lambert Anne-Sophie

Summary: Severe obesity with various complications is a growing public health problem in childhood. Due to the lack of available hygienic and dietary therapeutic solutions, bariatric surgery has become, in recent years, one of the only effective treatments for severe obesity to induce persistant weight loss and reduce complications.Material and method: We analyzed a cohort of 162 patients followed in the specialized obes...

Associations between weight-related anthropometric measurements and occurrence of breast development, pubic hair and menarche

S. Bruserud Ingvild , Roelants Mathieu , B. Júlíusson Peacute;tur

Background: The timing of puberty is influenced by different factors, one of which is body composition. The aim of the current study was to investigate if anthropometric indicators of body composition, body mass index(BMI), waist circumference(WC), subscapular skinfold(SSF) and body fat percentage(BF%) were differentially associated with occurrence of breast development, pubic hair and menarche in Norwegian girls.Methods:</strong...

Evaluation of new cutt-off points of the LHRH stimulation test in the diagnosis of central precocious puberty

Valls Llussà Aina , Murillo Vallés Marta , Martinez Couselo Silvia , Sol Ventura Paula

Introduction: Central precocious puberty (PPC) is defined by the appearance of sexual characters at a chronological age lower than -2.5DS of the average for the reference population. Diagnostic is clinical but the hormonal assessment is essential. Basal gonadotropin values are not enough for the diagnosis. Gonadotropin-releasing hormone (GnRH) stimulation tests evidence the activation of the hypothalamic-pituitary-gonadal axis, however there is controversy abo...
