We present the case of a five-day female admitted to our Paediatric Unit due to TSH elevation (bTSH 303 mIU/L) on routine neonatal screening for congenital hypothyroidism (CH). The patient was born at 38 weeks’ gestation by c-section presenting with adequate auxological parameters. Her mother suffered from Hashimoto’s disease, already diagnosed before pregnancy, and requiring Levo-thyroxine therapy (L-T4). Blood tests performed at five days of life revealed the pre...

From overt hyperthyroidism to normal thyroid function in TSH receptor activating mutations: reports of two families with novel pathogenetic variants and suggestion of a phenotypical sexual dimorphism

Introduction: Familial non-autoimmune autosomal dominant hyperthyroidism (FNAH) is a rare cause of childhood hyperthyroidism caused by an activating variant of the thyroid stimulating hormone receptor (TSHR) gene. This disorder may occur as a result of an autosomal dominant inheritance or sporadically through de novo variation. The severity of hyperthyroid symptoms is variable and phenotype differences have been described in subjects harbouring the same mutati...

Background: Central hypothyroidism (CeH) is a rare thyroid hormone deficiency due to an insufficient stimulation of a normal thyroid gland. Candidate genes for isolated CeH include TSHβ, TRH receptor (TRHR) or IGSF1 genes while the combined pituitary hormone deficits (CPHDs) are the consequence of defects in embryonic pituitary transcription factors or in the prokineticin receptor 2 (PROKR2).Patients series: Here we report nine males (M) and 15 fema...

Diagnosis and Management of Silver–Russell Syndrome: First International Consensus Statement

Netchine Irene

The first Consensus Statement on Silver Russell Syndrome has been held in 2015, on behalf of the COST Action BM1208 (European Network for Human Congenital Imprinting Disorders, http://www.imprinting-disorders.eu), ESPE, PES, APPES and SLEP with the participation of five representatives from a parent support group from different countries. It has been published in 2016 (ht...

GH Values in Serum and Blood Spots on Filter Paper Samples in Neonates Until 30 Days of Life by Electrochemiluminescence (ECLIA).

Growth Hormone deficiency (GHD) in newborn is an infrequent condition, which can cause threat to life due mainly to hypoglycemia that begins in the first week of life. A GH basal level (whether random or associated with spontaneous hypoglycemia) that distinguishes infants with GHD from those with GH sufficiency in the neonatal period is not conclusive. Few data have been reported about the GH measurements in serum and dried blood spots on filter paper samples in healthy neonat...

Silver-Russell Syndrome with 11p15 Epimutation: Clinical Analysis of Adrenarche, Central Puberty and Body Mass Index in a Cohort of French Children

Canton Ana , Brioude Frederic , Netchine Irene

Background: Silver-Russell syndrome (SRS) is characterized by intrauterine and postnatal growth retardation, a typical phenotype and feeding difficulties. It is related to 11p15 ICR1 hypomethylation in up to 50% of the cases. Some patients may exhibit signs of early puberty or premature adrenarche, including premature pubarche and/or an exaggerated adrenarche (high dehidroepyandrosterone sulfate (DHEAS) levels for chronological age). Despite early feeding difficulties, some ch...

Hyponatraemia Secondary to Exudative Eczema

Viseras Irene Pilar Fernandez , Ajzensztejn Michal

Background: Classically adrenal insufficiency presents with hyponatraemia and hyperkalaemia, however the differential may be of alternative origin. Atopic dermatitis is a common inflammatory skin disease of infancy and childhood. In severe cases, the exudation from wet lesions can produce serious complications such as infection+very rarely electrolytes abnormalities as seen in this case.Case report: A 6-month-old female infant was referred for endocrine ...

The Missing Link in Neonatal Diabetes

Viseras Irene Pilar Fernandez , Ajzensztejn Michal

Background: Neonatal diabetes mellitus (NDM) presents within 6months of life, is either permanent (PDM) or transient (TND). The incidence is 400 000/live births. Monogenic accounts for the majority of cases. We describe the case of what appears to be a familiar NDM with no current known cause.Case report: EM presented at 3 weeks old. She was born at term, IUGR (2.3 kg) with one day history of diarrhoea, vomiting and anorexia. There was no history of poly...

Fetal and Post-Natal Growth are Impaired in Children with Deletions of the GH1 Gene: Description of a Cohort of 14 Patients

Darvish Elsa , Legendre Marie , Netchine Irene , Amselem Serge , Brioude Frederic

Data on the birth parameters of patients with growth hormone deficiency are contradictory; recent studies suggest that congenital growth hormone deficiency is associated with impaired fetal growth. The main objective of this study was to describe the birth parameters of children with GH-1 gene deletion.This study included 13 patients (of 10 families) for whom a homozygous (or compound heterozygous) deletion of the entire GH1 gene has been identi...

Contribution of Direct Measurements of Steroids by Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) in Non-classical Adrenal Hyperplasia (NCCAH)

Agnani Helena , Houang Muriel , Egether Thibaut , Netchine Irene , Lamaziere Antonin

Background: To diagnose non classical congenital adrenal hyperplasia (NCCAH) and adrenal insufficiency (AI), current guidelines recommend ACTH test. Cutoffs for 17 hydroxyprogesterone (17OHP) and cortisol are derived from immunoassays values. Thanks to a recently developed and validated mass spectrometry approach (LC-MS/MS) we routinely quantify simultaneously 16 circulating steroids and we are able to speculate on new cut off values and uses.<p class="abs...
