概括
这项研究没有发现NR3C1基因变异与阿迪森氏病患者的骨矿物密度之间的显著联系. 标准皮剂似乎对骨的危害较小,但需要进行更大规模的研究.
科学领域:
- 内分泌学 在内分泌学.
- 遗传学 是一个遗传学.
- 骨的新陈代谢 骨的新陈代谢
背景情况:
- 阿迪森氏病 (AD) 需要终身葡萄糖皮质体 (GC) 替代疗法.
- 长期的GC过量与包括骨质疏松症在内的不良影响有关.
- 以前对阿尔茨海默病患者骨矿物质密度 (BMD) 的研究产生了相互矛盾的结果,可能是由于葡萄糖皮质体受体基因 (NR3C1) 的变异.
研究的目的:
- 为了研究NR3C1多态性 (rs6195,rs41423247,rs6189/rs6190) 对阿迪森病患者在标准GC替代过程中对BMD的影响.
- 为了确定特定的NR3C1基因变异是否与阿尔茨海默病患者的骨矿物质密度下降相关.
主要方法:
- 在使用PCR-RFLP和实时PCR的178名阿迪森病患者中,对三种NR3C1多态 (rs6195,rs41423247,rs6189/rs6190) 的基因定型.
- 通过双能X射线吸收计在腰椎和大腿部评估骨矿物质密度.
- 对89名患者的回顾性骨扫描数据的分析.
主要成果:
- 与绝经前女性和男性相比,绝经后妇女的BMDZ-score显著较低.
- 骨质疏松症和骨质疏松症很普遍,特别是在绝经后的妇女中.
- 虽然rs6195多态的携带者表现出较低的LS Z-score,但这并没有显著影响整体Z-score变化. 多重回归分析确定性别,年龄和体重是BMD的关键相关值,而不是NR3C1多态或GC剂量.
结论:
- 该研究没有在长期接受GC治疗的阿迪森病患者中研究NR3C1多态度和BMD之间建立显著的关联.
- 目前的标准GC替代剂可能对骨健康的风险比以前认为的要低.
- 建议对更大的患者队伍进行进一步的前性研究,以验证这些发现.

Bone Disorders
5.1K
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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
437
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Osteoclasts in Bone Remodeling
3.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Transducer Mechanism: Nuclear Receptors
2.4K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Drug Distribution: Tissue Binding
3.8K
Upon entering the systemic circulation, drugs can distribute into the interstitial and intracellular fluid of various tissue cells. This distribution is facilitated by the binding of drugs to different cellular components within tissues, which may lead to drug accumulation in specific areas. Drugs bound to tissue components serve as reservoirs that release free drugs back into the system, prolonging the drug's overall action. However, this accumulation can also result in local toxicity.

Bone Remodeling
40.3K
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.
