Hypothalamo-Pituitary-Adrenal (HPA) Axis in Infants Exposed to Corticosteroids During Fetal Life

Auriche Morgane , Houang Muriel , Giabicani Eloise , Mitanchez Delphine , Netchine Irène

Background: Prednisolone, prednisone, and hydrocortisone, are used during pregnancy, in women with thrombocytopenia, auto immune or inflammatory diseases. The current belief speculates on the absence of adverse effects on the hypothalamo-pituitary-adrenal (HPA) axis of the fetus, thanks to placental 11BHSD2 inactivation.Objective and Hypotheses: We analyzed the results of ATCH tests routinely performed in neonates expose...

Non-classic Congenital Adrenal Hyperplasia Causing Alleles among Adolescent Girls with PCOS – Genetical Study

Lidaka Lasma , Lazdāne Gunta , Gailīte Linda , Dzivite-Krisane Iveta

Introduction: Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies in adult women. Syndrome is characterised by hiperandrogenism, oligo/amenorrhoea and polycystic ovary morphology in ultrasound. Clinical signs of the syndrome usually start already during adolescent years. Non-classic congenital adrenal hyperplasia (NCAH), caused by several mutations in CYP21A2 (6p21.3) gene, is the most common differential diagnosis for girls presented with symptoms of P...

Perinatal features of children with Silver-Russell syndrome due to 11p15 loss of methylation

Darneau Diane , Giabicani Eloïse , Netchine Irène , Pham Aurélie

Context: Silver-Russell syndrome (SRS) is a rare imprinting disorder responsible for foetal and postnatal growth restriction. It is a clinical diagnosis based on Netchine-Harbison clinical scoring system in patients presenting with ≥ 4 items out of 6. Some of the items in this score are not assessable until the age of two years, such as growth retardation or feeding difficulties and body asymmetry can be difficult to identify in the first months of life. Ch...

Parental imprinting is an epigenetic process leading to monoallelic expression of certain genes depending on their parental origin. Imprinting disorders are a set of rare diseases that mainly affect growth and metabolism from birth to adulthood. These disorders are mainly due to methylation defects in imprinting control region that drive the abnormal expression of imprinted genes. Moreover, patients with imprinting disorders may present overlapping clinical features that can b...

Introduction: Congenital adrenal hyperplasia is the most common cause of primary adrenal insufficiency. It is a rare monogenic recessive disorder. In African setting in absence of neonatal screening, the diagnosis is still late, based on a clinical approach. During this clinical enquiry, information form past history or pedigree of the patient are of a huge importance and may revealed surprisesPatients and methods: In th...

Increasing Knowledge in IGF1R Defects: Lessons from 20 New Patients

Giabicani Eloïse , Willems Marjorie , Steunou Virginie , Chantot-Bastaraud Sandra , Rossignol Sylvie , Le Bouc Yves , Netchine Irène , Brioude Frédéric

Background: IGF1R is a keystone of foetal growth regulation by mediating the effects of both IGF-I and IGF-II. Recently the first clinical cohort of patients carrying an IGF1R defect has been reported from which a clinical score was established for diagnosis. Since no external validation of this score is available we assessed it in a large cohort of patients with identified IGF1R defects. Furthermore we aim at setting-up a functional test to ...

Investigation of Imprinting Alterations in MKRN3 and DLK1 in a Cohort of Girls with Central Precocious Puberty Through Specific DNA Methylation Analysis

Canton Ana , Steunou Virginie , Brito Vinicius , Laure Sobrier Marie , Montenegro Luciana , Bessa Danielle , Mendonca Berenice B , Netchine Irène , Latronico Ana Claudia

Background: Loss of imprinting has been implicated in the pathogenesis of several human diseases. Monogenic causes of central precocious puberty (CPP) were identified in families with loss-of-function mutations in two paternally expressed imprinted genes: Makorin zinc finger 3 (MKRN3) and Delta-like 1 homolog (DLK1). The role of imprinting defects in CPP has not been described so far.Objective: To inves...

Postoperative Water and Electrolyte Disorders and Affecting Factors in Children with Intracranial Tumors

Akbas Emıne Demet , Doger Esra , Ugurlu Aylın Kılınc , Bıdecı Aysun , Camurdan Orhun , Cınaz Peyamı

Introduction: Water and electrolyte disorders due to anterior and posterior pituitary deficiencies are common in children which are referred with intracranial tumors, especially arising from suprasellar and pituitary regions. But the prevelance and affecting factors of these disorders are not clear. We aimed that to determine the prevelance of postoperative water and electrolyte disorders and affecting factors in pediatric patients with intracranial tumors.<p class="abstex...

Differences of sex development (DSD) are congenital conditions with discordance between chromosomal, gonadal and/or anatomic sex. DSD can be syndromic or non-syndromic based on the presence or absence of somatic anomalies, respectively. Variants in several genes have been identified in association with errors of testis determination and male genital differentiation. However, despite technological advances, a genetic diagnosis is not achieved in nearly 50% of individuals presen...

Introduction: The incidence of Cushing disease (CD) is 0.7-2.4/year per million, andadolescents and children make up 10% of new cases annually. However, thesensitivity and specificity of tests used to diagnose CD in childhood may bepoor, resulting in difficulties in diagnosis and treatment. The aim was to reportpediatric CD patients attending our pituitary referral center for surgery and todescribe their diagnosis, treatment and long-term follow-up.<p clas...
