Objectives: In XLH, musculoskeletal outcomes of current treatment with oral phosphate (Pi)/active vitamin D are suboptimal for many patients. In a Phase 2, open-label study, we tested the hypothesis that KRN23 improves rickets and functional outcomes in XLH children.Methods: Fifty-two children with XLH (ages 5–12 years at baseline) received KRN23 subcutaneously biweekly (Q2W) or monthly (Q4W). At study entry, most participants had received oral Pi/a...

Adiposity, physical inactivity and sedentary behavior have become an increasing problem during the past decade and raise concerns about future health. Increased sedentary behavior may change the body composition by increasing the fat mass (FM) relative to the lean mass (LM). These changes may influence bone health. This study aimed at evaluating the influence of BMI and body fat percent (BF%) and LM on children’s bone health represented by bone mineral content (BMC), bone...

Pentraxin 3 (PTX3) is a highly conserved member of the long pentraxins subfamily produced in response to proinflammatory stimuli. Its biological roles have been associated to infection, female fertility and angiogenesis. We aimed to elucidate the role of PTX3 in the process of fracture healing.WT mice and mice deficient for the PTX3 gene (PTX3-KO) were used, after obtaining the approval from the Ethical committee. Cells from bone marrow and endosteal/per...

Rheumatoid arthritis (RA) is characterised by periarticular bone destruction leading to permanent disability. Some other forms of arthritis, such as arthritis in systemic lupus erythematosus (SLE), rarely produce bone lesions. Corresponding to that, inactivation of Fas produces a murine SLE-like phenotype, but alleviates bone loss during antigen-induced arthritis (AIA). Aim of this study was to identify cell populations differentially regulated in non-resorptive vs. resorptive...

Many disorders cause osteosclerosis, and many exclusively affect adults. Pediatricians are likely to encounter those that are Mendelian diseases, with most still classified as ‘dysplasias’ although now understood at the gene level. Thus, there is promise for defining their molecular and biochemical pathogeneses, and for developing targeted medical treatments. Sclerosing bone dysplasias too have become the ‘turf’ of the metabolic bone disease specialist. How...

Objectives: To prevent future osteoporosis, it is important to identify factors that affect bone health in adolescents as well as adults. This study aimed to examine the relationship between lipid profiles and insulin resistance and BMC in Korean adolescent population.Methods: Data from 706 boys and 621 girls who participated in the Korea National Health and Nutrition Examination Survey from 2008 to 2011 were analyzed. Lipid profiles were measured, and h...
