Final Height after Growth Hormone Treatment in Children with Chronic Renal Failure

Lonero Antonella , Bizzarri Carla , Delvecchio Maurizio , Emma Francesco , Strologo Luca Dello , Cappa Marco

Background: Growth retardation is seen in about 30% of children with chronic renal failure (CRF). Under-nutrition, anaemia, secondary hyperparathyroidism, acidosis, corticosteroid therapy and abnormalities in the GH/insulin like growth factor system have been implicated. Recombinant GH (rGH) therapy is recommended in children showing failure to maintain a normal height velocity despite optimized primary treatments.Objective and hypotheses: It has been de...

Lonero Antonella , Delvecchio Maurizio , Primignani Paola , Caputo Roberto , De alma Fabrizia , Luce Vincenza , Faienza Maria Felicia , Cavallo Luciano

Background: OTX2 is expressed in the human brain and plays a key role in the eye development. OTX2 mutations are reported in patients with ano/microphtalmia, optic nerve or optic chiasm hypoplasia, ocular coloboma and retinal dystrophies, associated in some cases with brain or pituitary abnormalities.Objective and hypotheses: Most of OTX2 mutations are nonsense or frameshift, more rarely missense mutations occur.Method: We...

Background: A significant number of long-term complications are reported in childhood acute lymphatic leukemia (ALL) survivors, and among them metabolic syndrome (MetS).Objective and hypotheses: To evaluate the prevalence of features of MetS. In addition, we evaluated the presence of steatohepatitis which is described in association with MetS in otherwise healthy subjects.Method: We assessed waist circumference, triglycerides level...

Impact of Continuous Subcutaneous Insulin Infusion versus Multiple Daily Injections on Bone Health in Children and Adolescents with Type 1 Diabetes

Faienza Maria Felicia , Delvecchio Maurizio , Ventura Annamaria , Aceto Gabriella , Piacente Laura , Zecchino Clara , Colucci Silvia , Grano Maria , Cavallo Luciano , Brunetti Giacomina

Background: Type 1 diabetes (T1DM) is associated with low bone mineral density (BMD) and bone alterations, probably due to lack of insulin and chronic hyperglycemia. Sclerostin and Dickkopfs-1 (DKK-1) are Wnt signaling inhibitors involved in bone remodelling.Objective and hypotheses: To assess serum levels of DKK-1 and sclerostin in T1DM children and adolescents on continuous subcutaneous insulin infusion (CSII) or multiple daily therapy (MDI). We hypoth...

Introduction: Previous reports support the hypothesis of an age dependent derangement of the hypothalamus¬Ėpituitary axis occurring in PWS subjects. In this context, transition years represent an important phase of growth process when somatic development reaches its completion. In the general population, GH deficiency (GHD) during the transition phase is associated with deterioration of body composition, metabolic alterations and reduced bone mineral density. PWS subjects ...

Low Bone Mineral Density is Associated to Poor Glycemic Control and Increased Dickkopf-1 (DKK-1) Serum Levels in Children and Adolescents with Type 1 Diabetes

Faienza Maria Felicia , Delvecchio Maurizio , Fusillo Anna , Lonero Antonella , Zecchino Clara , Acquafredda Angelo , Piacente Laura , Grano Maria , Cavallo Luciano , Brunetti Giacomina

Background: Decreased bone mineral density (BMD) and increased fracture risk have consistently been observed in type 1 diabetes mellitus (T1DM). The influence of T1DM on BMD seems to depend on gender or patient’s age and to occur early after T1DM diagnosis. The mechanisms of decreased BMD in T1DM patients are still unknown.Objective and hypotheses: To investigate the serum levels of dickkopf-1 (DKK-1), a Wnt signaling inhibitor which decreases bone ...

Mechanism of Bone Disease in Prader-Willi Syndrome

Background: Low bone mineral density (BMD) is found in up to 50% of adolescents and adults with Prader-Willi syndrome (PWS). High fracture risk has been described in adult PWS patients. This bone fragility could be due to inadequate gonadal hormones levels during pubertal development, and to relative growth hormone insufficiency during childhood and adolescence. However, the mechanism/s of low BMD in PWS have not been clarified.Objective and hypotheses: ...

Background: The primary goal of GH treatment in GHD children and adolescents is to normalize height, in order to attain an adult height within the target height (TH) range.Aim: to investigate height improvement in GHD paediatric patients treated with GH in our Country.Subjects: 737 patients with isolated GHD (39.5% females) from 13 tertiary Centres for Paediatric Endocrine Care...

RANKL and Osteoprotegerin Serum Levels in Obese Children and Adolescents

Background: There is growing evidence of a correlation between fat and bone metabolism at both the clinical and molecular levels, although the systemic regulators have not been clearly identified. The receptor activator of nuclear factor kB ligand (RANKL) and its soluble decoy receptor, osteoprotegerin (OPG), are involved in bone resorption and vascular calcification. OPG levels has been related with insulin resistance in adult obese subjects.Objective a...

Background: The replacement therapy with levo-thyroxine (LT4) in congenital hypothyroidism (CH) aims to ensure normal growth and neuropsychological development. Few data are available about the appropriate dose during childhood and early adolescence.Objective and hypotheses: i) To evaluate LT4/kg per day requirement from diagnosis until 12 years of age; ii) to assess any differences in relation to the different etiology of CH as concern...
