概括
患有格雷夫斯病 (GD) 的青少年在诊断时表现出低骨微架构 (脊椎骨分数,TBS). 虽然骨矿物质密度有所改善,但TBS的恢复是不完整的,这强调了早期对骨健康的最佳甲状腺激素控制.
科学领域:
- 儿科内分泌学 儿科内分泌学
- 骨的新陈代谢 骨的新陈代谢
- 格雷夫斯病的管理
背景情况:
- 在患有格雷夫斯病 (GD) 的青少年中,纵向骨健康数据很少.
- 格雷夫斯病及其治疗可能会影响年轻人的骨健康.
- 评估骨矿物质密度 (LSBMD) 和微架构 (TBS) 对于监测青少年GD患者至关重要.
研究的目的:
- 纵向评估腰椎骨矿物质密度 (LSBMD) 和椎骨分数 (TBS) 在患有格雷夫斯病的青少年中的变化.
- 为了确定影响骨健康恢复的因素.
- 了解疾病持续时间和甲状腺激素水平对骨参数的影响.
主要方法:
- 招募了41名患有GD的青少年,在基线和随访 (中位数2.2年) 测量LSBMD Z-score (LSBMDZ) 和TBS Z-score (TBSZ).
- 使用 iNsight 软件分析了 TBS.
- 使用渐进回归来确定骨参数变化的预测因素,包括时间加权的自由甲状腺素 (FT4).
主要成果:
- 在诊断时,最近被诊断出GD (RGD) 的青少年中有18%的LSBMDZ低,58%的TBSZ低.
- 虽然LSBMDZ在随访时正常化,但TBSZ仍然明显低于零 (p=0.007).
- 观察到LSBMDZ和TBSZ的改善,但随着疾病持续时间的延长而下降;FT4负面预测TBSZ的改善.
结论:
- 低TBS在新诊断的儿科GD患者中很常见,表明骨微架构受损.
- 骨矿物质密度恢复,但TBS显示不完全恢复,表明持续的微型架构缺陷.
- 在GD管理的早期保持最佳的FT4水平对于改善和保存青少年的骨微观架构至关重要.

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...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
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...

01:17Hormones and Bone Tissue
2.9K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
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...

01:40Bone Remodeling
38.5K
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.

01:09Spongy Bone
5.3K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:27Growth of Cartilage and Bone Tissue
3.5K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
