| Outline of Final Research Achievements |
We have reported that patients with type 2 diabetes mellitus have an increased bone fragility caused by poor bone quality because the elevated risk of fractures is observed despite their higher bone mineral density compared with non-diabetic subjects. However, any factors associated with poor bone quality remains unclear. Elevated levels of homocysteine and 8-OHdG, which are surrogate markers reflecting induction and tissue damages of oxidative stress, were significantly and positively associated with the presence of vertebral fractures independent of bone mineral density. These findings suggested that elevated oxidative stress was involved in aggravation of bone quality.
