Does serum osteoprotegerin level relate to fragility fracture in elderly women with low vitamin D status?
The data demonstrate a relative imbalance between bone formation and resorption associated with fragility fracture in elderly women with low vitamin D status. The authors suggest that compensatory elevation of serum OPG, particularly with reduced bone formation, is insufficient to limit bone loss leading to fracture.
These results suggest that not only the amount of atherosclerosis, but also arterial remodeling and lipid deposition in plaques, are influenced by systemic factors. The nonhomogeneous distribution of inflammation in atherosclerotic arteries supports the hypothesis that plaque inflammation is locally affected.
