概括
氧化应激 (OS) 与慢性病 (CKD) 患者的骨矿物质密度 (BMD) 较低有关. 这项研究发现,增加的OS标志物和降低的抗氧化活性与CKD严重程度和减少的BMD相关,这表明OS在CKD中有助于骨质疏松症.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 内分泌学 在内分泌学.
- 生物化学 生物化学
背景情况:
- 慢性病 (CKD) 与氧化压力 (OS) 的增加以及骨质疏松症 (OP) 的更高风险有关.
- 在CKD患者中,骨和骨矿物密度 (BMD) 之间的确切关系尚不清楚.
- 了解这种联系对于预防CKD中的OP至关重要.
研究的目的:
- 在患有CKD的个体中调查BMD和OS之间的关联.
- 探索CKD严重程度如何影响OS和BMD水平.
主要方法:
- 一项病例控制研究,涉及150名CKD患者 (1-5阶段) 和150名健康对照.
- 使用DEXA测量腰椎,大腿和远端半径的BMD.
- 评估了OS生物标志物 (8-OHdG,MDA) 和抗氧化剂反应 (PON1),以及维生素D水平.
主要成果:
- 与对照组相比,CKD患者的BMDT-score显著降低.
- OS生物标志物 (8-OHdG,MDA) 增加,而抗氧化活性 (PON1) 随着CKD的严重程度而下降.
- 在PON1和BMD之间观察到正相关性,而8-OHdG和MDA与BMD之间显示出负相关性.
结论:
- 慢性病患者经历了显著的氧化压力,随着疾病的进展而恶化.
- 氧化应激与CKD的骨矿物质密度有负相关性.
- 这些发现表明氧化压力在CKD患者骨质疏松症的发展中起着作用.

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 kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.
