- 骨矿物质密度评估 骨矿物质密度评估
- 药理疗法 药理疗法 药理疗法
背景情况:
- 监测骨矿物质密度 (BMD) 对于评估骨质疏松症治疗疗效至关重要.
- 定量计算断层扫描 (QCT) 可以测量脊椎体积 BMD (vBMD).
研究的目的:
- 评估抗吸收性和骨质合成疗法对脊柱vBMD的现实影响.
- 使用QCT数据比较不同骨质疏松症药物的疗效.
主要方法:
- 分析了来自402名年龄≥50岁,基线vBMD较低的患者的1145个vBMD测量结果.
- 使用线性混合模型估计对vBMD的治疗效应,并考虑混因素.
- 在每个患者的多次QCT扫描中追踪了相同的脊椎.
主要成果:
- 特里巴拉提德显著增加了每年4.27毫克/毫升的轨道肌内vBMD,每年4.27毫克/毫升.
- 抗吸收药物 (口服和静脉双酸盐,代诺苏马布) 在vBMD中显示微小到无意义的变化.
- 药物假期与vBMD显著下降有关 (每年-1.58毫克/毫升).

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:31Osteoclasts in Bone Remodeling
2.8K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...
