Background: We have recently reported the molecular diagnosis of two patients with severe growth failure associated with a spectrum of early-onset autoimmune disease and immunodeficiency. Heterozygous de novo mutations, c.1847_1849delAAG (p.E616del) and c.1276T>C (p.C426R), in the STAT3 gene were found. Functional in vitro studies of these variants are presented.Objective and hypotheses: We...

The role of insulin resistance and pancreatic β-cell dysfunction in the development of prediabetes in obese adolescents

MinkovaNadezda , Latyshev Oleg , Kiseleva Elena , Okminyan Goar , Romaykina Daria , Samsonova Lubov

Background: The pathophysiology of type 2 diabetes mellitus (T2DM) is based on defective insulin secretion by pancreatic β-cells and the inability of insulin-sensitive tissues to respond appropriately to insulin. Young people have a more aggressive course of the disease. However, the impact and sequence of pathological mechanisms involved in the development of T2DM in adolescents hasn’t been established. Diagnosis of the prediabetes in time can be u...

Case presentation: We report the case of Imad, a 2-year- old Algerian boy referred with a 2-month history of polyuria and polydipsia. Diabetes insipidus was diagnosed by confirming hypernatremia with hyperosmolar serum and inappropriately dilute urine. His polyuria and polydipsia improved dramatically using the oral vasopressin analog. The child had no clinical signs of underlying disease, serum tumor markers were not detected and a skeletal survey suggested n...

Endocrine-Metabolic Characterization of Pediatric Patients with Craniopharyngioma: A Single-centre Cohort study

Pedicelli Stefania , Sette Giulia , Cianfarani Stefano , Cappa Marco

Craniopharyngioma is a rare, embryonic malformation of the sellar/parasellar region with low histological grade. In childhood-onset craniopharyngioma (CoCR), endocrine dysfunctions, severe obesity and metabolic syndrome (MetS), neurological impairment and reduced quality of life have been described as consequences of both localization and treatment. To characterize a population with CoCR and to correlate endocrine/metabolic sequelae with different surgery approach we performed...

Longitudinal Study on Body Composition, Insulin Sensitivity and β-cell Function in SGA Adults from Stop of Long-term GH Treatment until 5 Years after Stop

van der Steen Manouk , Kerkhof Gerthe F. , Hokken-Koelega Anita C.S.

Background: GH treatment results in a decrease in fat mass (FM) and insulin sensitivity (Si), and an increase in lean body mass (LBM). Only limited data are available on the longitudinal changes after discontinuation of GH treatment in SGA adults, aged 21 years.Objective and hypotheses: To assess longitudinal changes in body composition (BC) and glucose homeostasis after stop of GH treatment in SGA adults.Method: 197 previously GH-...

Case Report: rare case of genetic neurohypophyseal diabetes insipidus associated with congenital hypopituitarism: when the fluid deprivation test does not make the diagnosis

Ferri Chiara , Palmoni Monica , Finamore Martina , Mascaro Rossella , Polenzani Ilaria , Rizzi Alessia , Magnacavallo Annalia , Meroni Silvia , Bucolo Carmen , Barera Graziano , Pozzobon Gabriella

Six-year-old female, diagnosed with GH deficiency at another Center (H: -3.13SDS; H peak with clonidine 5.7ng/mL, with insulin 1.2ng/mL). Brain MRI at diagnosis: small pituitary gland, ectopic neurohypophysis, normal stalk, right internal carotid artery aplasia. At 10 years onset of polyuria-polydipsia syndrome (PPS) (4L/day–154ml/kg/die); mood disorders and ADHD diagnosis were also reported. A fluid deprivation test was performed, lasting 22 hours (pre: S-Osm 275mOsm/L,...

The Optimal Dosage of Vitamin D Supplement for Vitamin D deficiency in Korean Children and Adolescents

Yang Seung , Hee Yi Kyung , Kim Eun Young , Hwang Il Tae

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...

Primary Thirst Defect is a Rare But Important Complication Following Surgery for Hypothalamic Hamartoma and Intractable Epilepsy

Giri Dinesh , Blair Jo , Das Urmi , Dharmaraj Poonam , Senniappan Senthil , Malluci Connor , Benedetta Pettorini , Pizer Barry , Burns Sasha , Didi Mohammed

Background: Diabetes insipidus (DI) is a well-recognized post neuro surgical complication arising after hypothalamic-pituitary surgery. DI occurring in the post-operative period can be transient happening within 24–48 hour of surgery, secondary to trauma to the connections between the magnocellular bodies and the nerve terminals in the posterior pituitary, or to axonal shock from disturbances in the vascular supply to the pituitary stalk and posterior pituitary.<p cla...

Leptin Replacement Improves Central Ventilation in a Patient with Congenital Leptin Deficiency: First Report in Childhood

Lucaccioni Laura , Davies Philip L , Gibson Neil A , Farooqi Sadaf , Shaikh M Guftar

Background: Congenital leptin deficiency (CLD) is characterized by severe early-onset obesity due to hyperphagia and impaired satiety. The impact of obesity in obstructive sleep apnoea hypopnoea syndrome (OSAHS) was originally reported as mechanical, but recent data suggest that adipokines may influence central ventilation. We highlight that treatment with recombinant human leptin (RHL) in CLD with OSAHS improves ventilation before weight loss.Case prese...

Acute Phase Proteins and Endocrine Dysfunction after Traumatic Brain Injury in Childhood

Verigaki Olga , Papassotiriou Ioannis , Prodromou Neofytos , Sfakianos George , Chrousos George , Kanaka-Gantenbein Christina

Background: Endocrine impairments, such as diabetes insipidus (DI), growth hormone deficiency (GHD) and, to a lesser degree, thyroid or cortisol deficiencies, have been reported after traumatic brain injury (TBI) in adults and much less in children both at the acute post-traumatic phase and after a lag period of time. However, no prospective data exist on the endocrine and acute phase protein response to TBI in childhood.Aim/objective: To unravel possibl...
