概括

对类风湿性关节炎 (RA) 的阿巴塞普治疗增加了骨质形成标志物,但导致了暂时的骨质损失,可能是由于甲状腺上腺激素 (PTH) 水平的增加. 需要进一步的研究来理解RA.

科学领域:

类风湿病学类风湿病学
骨的新陈代谢骨的新陈代谢
免疫学免疫学免疫学

背景情况:

类风湿性关节炎 (RA) 与骨质损失有关,不仅仅是由炎症解释的.
关节炎治疗对骨代谢的影响及其预防骨损失的能力需要进一步研究.

研究的目的:

评估阿巴切对 RA 患者血清标记物和骨周转调节物的影响.
评估骨矿物质密度 (BMD) 的变化,骨健康参数和侵蚀.
探索骨代谢标志物与临床结果之间的相关性.

主要方法:

对33名活跃的血清阳性RA患者进行前性观察性研究,之前的生物疗法失败了,开始服用atacept.
在12个月内定期监测血清骨循环标记物 (CTX,P1nP,B-ALP),骨调节剂 (Dkk-1,硬质素,维生素D,PTH,OPG,RANKL),骨质量和放射评分 (mSvdH,BHI,MCI).
评估疾病活性和葡萄糖皮质激素的使用.

主要成果:

在6个月和12个月观察到骨形成标志物 (B-ALP,P1nP) 的显著增加.
甲状腺上腺激素 (PTH) 在6个月过渡性增加,但在12个月没有持续.
在12个月内,骨健康指数 (BHI) 和甲指数 (MCI) 显著下降;在6个月后,腿部部短暂的BMD下降.
在12个月后发现P1nP变化和mSvdH得分变化之间的相关性.

结论:

在RA患者中,阿巴塞普的治疗与骨形成标记物的增加有关.
观察到的过渡性骨损失可能与PTH水平的暂时上升有关.
需要进一步的研究来阐明阿巴塔塞普特,骨代谢和RA骨健康之间的复杂关系.

Osteoclasts in Bone Remodeling

Osteoclasts in Bone Remodeling

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...

Bone Remodeling

Bone Remodeling

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.

Bone Disorders

Bone Disorders

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...
