Pituitary Function after Mild to Severe Traumatic Brain Injury in Children 2–18-Years-Old: A Prospective Study

Braun Karine , Briet Claire , Toussaint Patrick , Trifunovic Helene Bony , Boudailliez Bernard

Background: In recent years, traumatic brain injury (TBI) has been identified as a significant cause of pituitary dysfunction in children. Paediatric prospective studies are rare especially for mild TBI.Objective and hypotheses: The aim of this present study was to evaluate the frequency of hypopituitarism after mild, moderate and severe TBI in hospitalized children, and determining factors of this deficiency.Method: A prospective ...

Are Children with Congenital Primary Hypothyroidism Overtreated?

Sechter Claire , Vasseur Francis , Cartigny-Maciejewski Maryse , Gueorguieva Iva , Stuckens Chantal , Weill Jacques

Background: Treatment of congenital primary hypothyroidism (CPHT) fluctuates between two opposite risks for the neuro-cognitive development in a critical window during the neonatal period, under- and over-treatment.Objective: To investigate the relevance of current international recommendations of 10–15 μg/kg per day for L-thyroxine (lT4) doses in CPHT.Method: fT4 and TSH were measured...

Between 3 to 4 Years after Severe Traumatism Brain Injury 22% at Least of Children and Adolescents do have Persistent Pituitary Dysfunction

Dassa Yamina , Personnier Claire , Crosnier Helene , Chevignard Mathilde , Bourgeois Marie , Viaud Magali , Polak Michel

Background: Traumatic brain injury (TBI) is common in childhood but long-term endocrine consequences are yet to be documented by prospective data.Objective and hypotheses: We have previously demonstrated in prospective study that, 1 year after severe accidental TBI (ATBI) or inflicted TBI (ITBI), children and adolescents may present pituitary and growth hormone (GH) dysfunction. We present here the follow-up of this population to determine whether or not...

Continuous versus discontinuous administration of gonadotropin in neonates with congenital hypogonadotropic hypogonadism

Avril Tristan , Hennocq Quentin , Lambert Anne-Sophie , Simon Dominique , Leger Juliane , Martinerie Laetitia , Bouvattier Claire ,

Context: Newborns with Congenital hypogonadotropic hypogonadism (CHH) have an impaired postnatal activation of the gonadotropic axis. Substitutive therapy with recombinant gonadotropins can be proposed to mimic physiological male mini-puberty during the first months of life.Objective: To retrospectively compare the clinical (penile size, volume and testicular descent) and biological efficacy (serum concentrations of test...

Initial response to thionamide medication in young people with newly diagnosed thyrotoxicosis

Wood Claire , Morrison Niamh , Cole Michael , Donaldson Malcolm , Dunger David , Wood Ruth , Pearce Simon , Cheetham Tim

Methods: Patients commenced 0.75mg/kg carbimazole (CBZ) daily with randomisation to either BR or DT. We examined baseline patient characteristics, CBZ dose, time to serum TSH/FT4 normalisation and BMI Z-score. Results: There were data available from 80 patients (baseline) and 78 patients (61 female) at 6 months. Mean CBZ dose was 0.9 mg/kg/day (BR) and 0.5 mg/kg/day (DT). There was no difference in the time taken for...

Impact of estrogen therapy on pubertal growth in Turner syndrome

Trouvin Marie-Agathe , Thomas-Teinturier Cecile , Bouvattier Claire , Duranteau Lise , Linglart Agnes ,

Short stature and hypogonadism are frequent symptoms in Turner syndrome (TS). In most cases, puberty must be induced but pubertal induction modalities are not consensual. Moreover, pubertal induction impact on final height and pubertal growth spurt has not been studied in depth. Our aim was to study factors influencing final height during pubertal induction in TS. Retrospective cohort of 45 TS girls followed in a single center: Bicetre hospital. We recorded auxological paramet...

Hyperparathyroidism after three years of burosumab in children affected with x-linked hypophosphatemia

V Zhukouskaya Volha , Ertl Diana-Alexandra , Berkenou Jugurtha , Audrain Christelle , Bardet Claire , Rothenbuhler Anya , Linglart Agnes

Background/aim: Hyperparathyroidism (HPHT) is a common feature in patients with X-linked hypophosphatemia (XLH) especially when treated with vitamin D analogues and phosphate supplements. Although the exact mechanism is not clear, it is assumed that phosphate supplements taken chronically stimulate parathyroid hormone (PTH) secretion. We prospectively assessed the effect of a novel pathogenetic treatment anti-FGF23 (burosumab) on PTH levels in children with XL...

MCM4 deficiency causing Natural Killer and Glucocorticoid Deficiency with DNA repair defect (AR-NKGCD) - a large cases series from the Irish Traveller population

Fedorczak Anna , Reynolds Claire , Somers Eric , Ann Lynch Sally , Leahy Ronan , M O’Connell Susan

A new condition, unique to Irish Travellers, was first described clinically as autosomal recessive natural killer and glucocorticoid deficiency (AR-NKGCD) ORPHA:75391 in 2008 and was attributed to recessive founder variant in MCM4/PRKDC gene in 2012. Irish Travellers are an indigenous endogamous population numbering ~40,000 in the Republic of Ireland. AR-NKGCD is characterised by short stature, glucocorticoid and natural killer cell deficiency and is a disorder of DNA repair. ...

Pharmacokinetics and Pharmacodynamics of a Human Monoclonal Anti-Fibroblast Growth Factor 23 Antibody (KRN23) Following 4 Month Intra-Dose Escalation in Adults with X-Linked Hypophosphatemia

Zhang Xiaoping , Imel Erik , Ruppe Mary , Weber Thomas , Klausner Mark , Ito Takahiro , Vergeire Maria , Humphrey Jeffrey , Glorieux Francis , Portale Anthony , Insogna Karl , Peacock Munro , Carpenter Thomas

Background: In X-linked hypophosphatemia (XLH), abnormally elevated serum fibroblast growth factor 23 (FGF23) results in low renal maximum threshold for phosphate reabsorption (TmP/GFR), low serum phosphorus (Pi), inappropriately normal 1,25-dihydroxyvitamin D (1,25(OH)2D) and development of rachitic deformities.Methods: Up to four s.c. KRN23 doses were given every 28 days to 28 adults with XLH according to a dose-escalation algorithm (0.05&#1...
