概括
技术-99甲基二酸盐 (99Tc-MDP) 有助于维护腰部骨矿物质密度在绝经后妇女与差异化甲状腺癌和骨质疏松症. 常规的/维生素D补充剂本身并不能防止这个患者群体的骨质损失.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 骨的新陈代谢 骨的新陈代谢
背景情况:
- 甲状腺刺激激素 (TSH) 抑制疗法是分化甲状腺癌 (DTC) 和骨质疏松症的绝经后患者骨脆弱性的关键因素.
- 在这种特定的临床背景下,对双酸盐,包括99Tc-MDP的使用存在有限的证据.
研究的目的:
- 评估99Tc-MDP在改善经更年期妇女的骨质疏松症的疗效,这些妇女接受了TSH抑制疗法.
- 为了比较99Tc-MDP加/维生素D与单独/维生素D对骨矿物质密度 (BMD) 和骨周转指标的影响.
主要方法:
- 一项开放标签,前性研究,涉及102名绝经后妇女,在TSH抑制下患有DTC和骨质疏松症.
- 参与者被随机分配,接受/维生素D补充剂或/维生素D加99Tc-MDP.
- 用DXA评估腰椎骨质量,并在基线和6个月和12个月后测量骨周转标志物.
主要成果:
- 与/维生素D组相比,99Tc-MDP组在12个月后显示腰部 BMD 的显著增加.
- 在12个月的时间里,/维生素D组的腰椎骨质量显著下降.
- 与单独的/维生素D相比,99Tc-MDP治疗导致骨循环标志物 (增加P1NP,减少β-CTX) 的显著改善.
结论:
- 99Tc-MDP是一种安全的治疗选择,用于在 TSH 抑制下维持腰部 BMD 在患有 DTC 和骨质疏松症的绝经后妇女中.
- 仅仅补充/维生素D不足以预防这一患者群体在1年随访期间的骨质损失.
- 这些发现支持99Tc-MDP在接受TSH抑制治疗的DTC患者的骨健康管理中的潜在作用.

Hormones and Bone Tissue
3.7K
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...

Therapeutic Drug Monitoring: Overview and Classification
306
Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood at designated intervals to ensure the drug concentration stays within a therapeutic range. This monitoring is crucial for optimizing individual dosage regimens, enhancing therapeutic efficacy, and minimizing drug-related toxicity. TDM is vital for drugs with narrow therapeutic windows, significant variability in pharmacokinetics, and a clear correlation between plasma levels and...

Therapeutic Drug Monitoring: Affecting Factors
200
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...

Bone Remodeling
40.2K
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.

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
