在患有軟骨發育不全症的兒童中,早期用vosoritide 治療顯示了對脊柱健康的有希望的結果. 沃索里提德改善了脊柱通道宽度和减少了异常的脊柱曲线,可能降低脊柱狭窄的风险.
科学领域:
- 儿科整形外科 儿科整形外科
- 医学遗传学 医学遗传学
- 药理学 药理学是指药理学的学科.
背景情况:
- 骨质疏松症是一种遗传性疾病,由于内分泌骨骨化受损,导致不成比例的矮身和骨变形.
- 脊柱并发症,如胸脊柱缩症 (TLK) 和脊柱狭窄症,在骨质疏松症中很常见.
- 沃索里提德是一种已批准的针对性治疗阿德罗普拉西亚的药物,主要以促进骨生长而闻名.
研究的目的:
- 评估沃索里提德对儿童脊髓形态的影响.
- 为了评估跨足距离 (IPD),腰椎脊柱通道宽度和TLK角度的变化.
- 确定沃索里提德在改善幼儿脊柱健康方面的安全性和有效性.
主要方法:
- 随机,双盲,安慰剂控制的CANOPY ACH-2I第二阶段研究涉及75名0至5岁以下的儿童.
- 脊柱放射图在基线分析,并在治疗1年后用vozoritide或安慰剂.
- 测量包括IPD,斜腰脊柱管宽度和TLK角度,使用ANCOVA进行分析.
主要成果:
- 与安慰剂相比,Vosoritide治疗在一年后导致IPD和腰椎道宽度 (L1-L5) 显著改善.
- 在L4脊椎显示IPD和通道宽度最显著的改善与vosoritide.
- 伏索里提德可降低TLK角度在较小的儿童的进展,在0.5至<5岁的儿童中显示出更大的益处,较少的患者患有病理TLK角度.
结论:
- 早期给患有无形质细胞增生症的儿童服用沃索里提德,对脊柱形态产生了积极的影响.
- 用沃索里提德治疗可能有助于使脊柱通道尺寸正常化,并减少脊柱曲异常的发生率.
- 这些发现表明,沃索里提德可以减轻儿科无色素增生症患者脊柱狭窄的风险.

Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

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...
