| Research Abstract |
Patients with chronic kidney disease (CKD) including dialysis patients have high risk of bone fracture. In order to elucidate the mechanisms underlying bone fragility in CKD patients we analyzed the bone material properties which indicate chemical composition. The bone samples from CKD represented lower storage modulus, which is one of mechanical properties, accompanied with the changes of bone chemical composition. These changes were influence on bone mechanical properties independent of bone mineral density, bone turnover, and hormones regulating bone metabolism. In addition, changes of bone chemical composition were improved by preventing accumulated uremic toxins in sera. These results suggest that controls for uremic conditions are possible new therapeutic approach for bone fragility.
