对于壮症而言,Pegvisomant治疗可能会导致骨密度降低和外围骨微观结构的改变,尽管骨转换标记稳定. 这些骨质缺陷可能会导致治疗患者的脆弱性.
科学领域:
- 内分泌学 在内分泌学.
- 骨生物学 骨生物学 骨生物学
- 代谢性骨疾病 代谢性骨疾病
背景情况:
- 巨症与骨折率的增加和持续的骨微观结构异常有关,即使在治疗后.
- 维索曼特是一种生长激素受体对抗剂,其对壮症患者骨微观结构的影响以前是未知的.
研究的目的:
- 研究维索曼治疗对骨矿物质密度,骨循环标志物和骨微型架构的长期影响.
主要方法:
- 一项纵向研究评估了20名接受维索曼特治疗的壮病患者的面积骨矿物质密度 (BMD) 和骨周转标记 (BTMs).
- 一项横截面研究评估了17名使用HRpQCT长期接受佩格维索曼特治疗的患者的体积 BMD,微型架构和骨强度,并将其与对照组和其他壮症组进行比较.
主要成果:
- 长期的佩格维索曼治疗显示,腰椎骨质量得到改善,但男性的部骨质量下降.
- 与健康对照人群相比,长期服用佩格维索曼特的患者的骨较大,体积骨密度降低,并破坏了轨道骨微架构.
- 骨循环标志物最初下降,然后在佩格维索曼治疗期间稳定.
结论:
- 这项研究揭示了与pegvisomant治疗的巨患者的外围骨体积 BMD 和微型架构的缺陷.
- 稳定的骨转化标志物在长期佩格维索曼治疗中被观察到.
- 在HRpQCT中发现的骨质缺陷可能会导致治疗壮症的脆弱性.

Bone Remodeling
Bone Disorders
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...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
