使用更年期激素治疗 (MHT) 的女性减少了骨折风险. 在停止MHT后,骨折风险最初上升,然后随着长期使用而显著下降,特别是在老年人中.
科学领域:
- 生殖医学 生殖医学
- 老年学是一门学科.
- 药理学 药理学是指药理学的学科.
背景情况:
- 更年期激素治疗 (MHT) 与女性骨折风险降低有关.
- 有限的数据存在于MHT停止后骨折风险,特别是长期.
- 这项研究旨在估计过去的MHT用户在停药后长时间内骨折的风险.
研究的目的:
- 为了研究更年期荷尔蒙治疗停止后的长期骨折风险.
- 为过去的MHT用户提供可靠的骨折风险估计,随着他们的年龄增长.
主要方法:
- 一个嵌套的病例控制研究利用了英国的初级和二级保健数据 (CPRD GOLD和Aurum).
- 40岁以上有第一次骨折记录的女性与没有骨折的对照进行了匹配.
- 条件后勤回归分析了与MHT相关的骨折风险,并对混因素进行了调整.
主要成果:
- 与从未使用者相比,当前使用MHT与骨折风险降低有关.
- 在MHT discontinuation后的1-10年内,骨折风险增加,超过从未使用者的水平.
- 在戒药10年后,骨折风险低于从未使用过的人,特别是使用MHT持续时间较长的人.
结论:
- 在MHT停止后,骨折风险最初急剧增加,随后逐渐下降.
- 风险水平因MHT类型和持续时间而异,在停止后显著增加.
- 调查结果为有关MHT启动和停止的临床决策提供了信息,突出了骨折风险较高的时期.

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...

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

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...
