Background: Obesity during childhood has been demonstrated to exert profound and lasting effects on bone strength and fracture risk. Furthermore, obesity is characterized by chronic inflammation and oxidative stress, with an increase in the mediators of innate immunity. It has been found that skeletal homeostasis is influenced by immune cells. LIGHT (lymphotoxin-like inducible protein that competes with glycoprotein D for herpesvirus entry on T cells) is emerging among cytokin...

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...

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: 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...
