Electronic Devices and Single-Dose Dispensing Systems GH are the Most Efficient and Less Loss of Drug

Diez-Lopez Ignacio , Sarasua-Miranda Ainhoa , Elizalde Miriam Miriam , Lorente-Blazquez Isabel , Minguez Cristina , Martinez-Martinez Carlos

Background: Several pharmaceutical formulations marketed GHRH, were being restricted in their choice occasions. Three display groups: single-dose, pre-filled pens/vials and electronic devices, self-injection systems. The choice may contribute to a greater or lesser adherence and a difference in the final cost of treatment (drug loss), attributable to the device itself or presentation. Presentations that require reconstitution device load, partial doses or stop in Pen contribut...

Efficacy, Adherence, and Cost Study According to Pathology and Treatment Devices in Children Treated with GHRH

Diez-Lopez Ignacio , Sarasua-Miranda Ainhoa , Elizalde Miriam Miriam , Lorente-Blazquez Isabel , Minguez Cristina , Martinez-Martinez Carlos

Background: Currently there are three distinct groups of GH devices: single dose (JM), preloaded pen/vial (VM) systems and electronic devices (DE) autoinjector systems. The choice could determine a greater or lesser adherence and thus influence the final treatment efficacy.Objective: Comparison of the therapeutic efficacy as measured by growth rate (VC), IGF1 as a function of various clinical variables, indicating GH and device used.<p class="abstext...

Polyuria and Polydipsia: The Deep Waters of Diagnosis

Pozzobon Gabriella , Ferrarello Maria Piera , Damia Chiara Maria , Garbetta Gisella , Osimani Sara , Voto Andrea , Partenope Cristina , Pruccoli Giulia , Chiumello Giuseppe

Background: Polyuria and polydipsia must never be underestimated.Objective and hypotheses: A 7-year-old girl presented with polyuria, polydipsia and nocturia of 1 year duration, during which she underwent outpatient follow up with her general practitioner and urologist. No weight loss or other endocrine signs.Method: Polyuria was confirmed by water balance (120 ml/kg per 24 h), urinary osmolality (222 mmol/kg), plasma osmolality (2...

Mutation of the TSH Receptor Gene: a Longitudinal Study in Children with Non-Autoimmune Subclinical Hypothyroidism

Vigone Maria Cristina , Sonnino Micol , Guizzardi Fabiana , Frenna Marianna Di , Caiulo Silvana , Gelmini Giulia , Persani Luca , Weber Giovanna

Background: Neonatal screening strategies revealed an increase in hypothyroidism associated with an in-situ thyroid gland due to TSH receptor (TSHR) mutations. While there are many genetic and functional studies regarding TSHR mutations, few are found concerning the clinical course and long-term outcome of TSH resistance involving the pediatric population.Objective and hypotheses: To determine the impact of TSHR mutations on clinical course, biochemical ...

Idiopathic Central Diabetes Insipidus: a Case of Pediatric Xhantogranuloma

Pozzobon Gabriella , Damia Chiara , Voto Andrea , Ferrarello Maria Piera , Garbetta Gisella , Osimani Sara , Pruccoli Giulia , Partenope Cristina , Chiumello Giuseppe

Background: Xhantogranuloma of the sellar region (XG) is a very rare brain tumor and is clinically and pathologically distinct from classical adamantinomatous craniopharyngioma, but the differential diagnosis is difficult because there are no typical neuroradiological signes. The characteristic and the outcome of XG in children remain still unclear.Objective and hypotheses: We aimed to describe a case report of XG and multiple pituitary hormone deficienc...

Effects of Initial Levothyroxine Dose on Growth and Neurodevelopmental Outcomes During the First Year of Life in Children with Congenital Hypothyroidism

Esposito Andrea , D'Onofrio Gianluca , Cassio Alessandra , Corrias Andrea , Gastaldi Roberto , Vigone Maria Cristina , Wasniewska Malgorzata Gabriela , Weber Giovanna , Salerno Mariacarolina

Background: An important issue in the management of congenital hypothyroidism (CH) is the best initial dose of levothyroxine (L-T4) in order to achieve optimal neurocognitive outcomes. Both European and American guidelines suggest an initial dose of 10–15 μg/kg per die but trials on long-term effects of different doses within this range are lacking.Objective and hypotheses: This was a multicenter randomized trial to ev...

Unaltered Ratio of Circulating Levels of GH Isoforms after Administration of Different GH Provocative Tests in a Population of Short Stature Children

Rigamonti Antonello , Meazza Cristina , Bidlingmaier Martin , Muratore Valentina , Martina Luparia , Bini Silvia , Pagani Sara , Cella Silvano , Bozzola Mauro

Background: Human GH is a heterogeneous protein hormone consisting of several isoforms, the most abundant being 22 kDa- and 20 kDa-GH. The availability of analytical methods to measure these GH isoforms might represent a valuable diagnostic tool to investigate GH secretion in short stature.Objective and hypotheses: Aim of the present study was to measure circulating levels of 22 kDa- and 20 kDa-GH in children with different diagnosis of short stature suc...

Is Retesting in GH Deficient Children Really Useful?

Pagani Sara , Meazza Cristina , Gertosio Chiara , Donati Chaira , Scavuzzo Francesca , Pilotta Alba , Buzi Fabio , Larizza Daniela , Bozzola Mauro

Background: Patients with childhood-onset GH deficiency (GHD) are usually retested in late adolescence or young adulthood, after achievement of final height, to verify whether they need to continue GH treatment. Most of the patients found to have idiopathic GHD when tested as children have normal GH responses when retested in the early or late adolescence. Indeed, the 2007 Consensus guidelines for the diagnosis and treatment of GHD adults recommended that idiopathic GHD patien...

Persistent Müllerian Duct Syndrome Associated with Anorchia Caused by a Compound Heterozygous Mutation in the AMHR-II Gene

Rojo Jaime Cruz , Lorenzo Lucia Garzon , Fernandez Jone Agirregoitia , del Pozo Cristina Martinez , Picard Jean-Yves , del Pozo Jaime Sanchez

Background: The persistent Müllerian duct syndrome (PMDS) is a rare 46-XY disorder of sex development, characterized by the persistence of Müllerian derivatives (uterus, Fallopian tubes) in otherwise normally virilised males. The condition is transmitted as a recessive autosomal trait and is caused in most cases by a defect in either the anti-Müllerian hormone (AMH) or the AMH type-II receptor (AMHR-II) genes.Case report: We present a 9 ye...

Background: The correct diagnosis of growth hormone deficiency (GHD) and the definition of growth response in the management of growth hormone (GH)-treated children is controversial.Objective and hypotheses: To evaluate: i) short-term and long-term efficacy of GH treatment; ii) various criteria commonly used to define poor response to GH therapy and compare them in the same cohort of GHD patients.Method: Our study includes 94 child...
