摘要
Osteoporosis is an age-associated disease, resulting in impaired bone quality and increased risk for bone fractures. Patients with type 2 diabetes mellitus have-despite a normal or even increased bone mineral density-an increased risk for fractures, which is related to an imbalance between osteoblastic bone formation and osteoclastic resorption. Complex pathophysiological mechanisms associated with insulin resistance and hyperglycemia are involved in the deleterious effects on osteoblast function and bone formation. The quality and regimen of antidiabetic therapy are discussed as modulators of bone metabolism. Of great clinical importance is an assessment of the fall risk especially for diabetic patients, because late complications, such as neuropathy, but also side effects of medication can result in a significantly increased risk for falls. Lifestyle intervention is of advantage with respect to diabetes and osteoporosis prevention and therapy. Vitamin D supplementation results in favorable effects with a reduced risk for falls and also improvements of insulin sensitivity. According to published data, the safety and efficacy of specific medication for the treatment of osteoporosis (bisphosphonates, denosumab, selective estrogen receptor modulators) reveal no difference between patients with and without diabetes mellitus.
