Background: Mutations in the gene encoding LHX4, a homeodomain-containing factor with two LIM domains, are responsible for dominant hypopituitarisms with incomplete penetrance and variable expressivity. To date, only 14 unambiguous LHX4 mutations have been reported. Among those cases, 12 had an absent or ectopic posterior pituitary (EPP) and/or an abnormal sella turcica.Objective and hypotheses: To i) assess the contribution of LHX4 in combined pituitary...

Background: “Transient” Neonatal Diabetes Mellitus (TNDM) is a rare genetic beta cells dysfunction leading to hyperglycaemia that resolves in early childhood. About 80% of patients relapse during adolescence or adulthood. Glucose homeostasis had not been investigated in adulthood.Objective and hypotheses: To investigate insulin secretion and insulin sensitivity in adults affected with TNDM or in their 1st degree mutated relatives.</p...

Background: Sulfonylurea therapy (SU) allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel subunits (ND-K). Most of these patients have neurological and neuromotor developmental impairments whose changes under SU has not been studied in a systematic and prospective way in a large cohort.Objective and Hypotheses: To demonstrate the beneficial effect of SU on neuropsychological functio...

Background: ROHHAD(NET) syndrome has been proposed as an acquired neuroimmunological dysfunction. Aim of the study is to compare the phenotype of lymphocyte subpopulations in patients vs controls and to evaluate the plasma levels of pro-inflammatory cytokines/chemokines in ROHHADNET syndrome.Patients and Methods: We included 14 patients (9F;5M), selected by clinical criteria, matched with 11 controls with simple obesity ...

Agreement between Acth-low test and Insuline Tolerance Test in Patients with Risk Factors for Central Adrenal Insufficiency

Panciroli Marta , Angelelli Alessia , Fava Daniela , Patti Giuseppa , Napoli Flavia , Di Iorgi Natascia , Maghnie Mohamad

Background: Central adrenal insufficiency(CAI) is a potential life-threatening condition and a prompt diagnosis represents a clinical challenge; indeed, the Insulin Tolerance Test(ITT), gold standard for CAI diagnosis, can be contraindicated in some conditions. Aims were to evaluate the diagnostic value of the ACTH low test(ACTH-LT) compared to the ITT and to identify eventual determinants(primary diagnosis, risk factors, symptoms, baseline cortisol, hypothala...

Adult Height is impaired in females with Medulloblastoma and hypogonadism: Impact of Pubertal Timing

Ferraro Paola , Casalini Emilio , Fava Daniela , Maghnie Mohamad , Patti Giuseppa , Di Iorgi Natascia

Introduction and Aim of the Study: girls with previous pediatric medulloblastoma (MB) are at risk of short stature and impairment of the hypothalamic pituitary gonadal function due to multiple risk factors;our aim was to assess the impact of hypergonadotropic hypogonadism (HH) on growth up to final height (FH) in females with or without growth hormone deficiency (GHD).Methods: anthropometrics (height-Ht-SDS, BMI-SDS, Tan...

Longitudinal assessment of bone health index (BHI) as a measure of bone health in short-statured children before and during treatment with recombinant growth hormone

Holzapfel Lukas , Bettendorf Markus , Rabe Michael , Mittnacht Janna , Choukair Daniela , Schenk Jens-Peter

Introduction: Bone Health Index (BHI) determined by measurement of cortical thickness of metacarpalia II-IV in x-rays of the left hand represents a method to estimate bone health in children. Aim of this study was to investigate changes of BHI SDS in the course of growth hormone (GH) treatment.Method: 256 consecutive children with short stature (isolated GH deficiency (IGHD) n = 121, multiple pituitary hormone deficiency...

De Novo Formation of Neutralizing IGF-I Antibodies During rhIGF-1 Treatment in a Girl with IGFALS Deficiency as Distinct Adverse Event Interfering with Growth Promotion

Mittnacht Janna , Breil Thomas , Choukair Daniela , Duffert Christin , Hwa Vivian , Rosenfeld Ron , Bettendorf Markus

Background: IGFALS deficiency is a rare cause of GH insensitivity (GHI). We report a German girl with short stature who was born as 2nd child at 40 weeks of gestation. Her Caucasian parents were unrelated and healthy (target height 168 cm, SDS 0.2). She was born appropriately sized for gestational age (49 cm, SDS -1.2; 2950 g, SDS-1.2). Height (104.8 cm; SDS -2.94) and height velocity (5.1 cm / year; SDS -1.67) were reduced at the age of 6 years.</p...

Introduction: The association between ATD and AIG is very poorly characterized in pediatric age. We review the prevalence of the anti-gastric parietal cells antibodies (APCA) in young patients with ATD and we evaluated the development of AIG during follow-up, in order to define the usefulness of these markers for AIG screening in these patients.Patients and Methods: We evaluated 220 children and adolescents (11.28 ±...

Autoimmune Thyroid Diseases in Children and Adolescents with Maturity Onset Diabetes of the Young

Calcaterra Valeria , Regalbuto Corrado , Dobbiani Giulia , Vinci Federica , Montalbano Chiara , Larizza Daniela

Background and Aim: The relationship between T1DM and autoimmune thyreopathies is known and described, but the relationship between thyreopathies and other type of diabetes is not sufficiently clarified in pediatric age. The aim of our study was to assess the prevalence of autoimmune thyroid diseases (ATD) in children and adolescents with maturity onset diabetes of the young (MODY) in comparison with patients with T1DM and control group....
