概括

在临床隔离综合征 (CIS) 患者中,高剂量维生素D补充剂显著降低了多发性硬化症 (MS) 疾病活性. 这一发现表明维生素D可能作为早期多发性硬化症的补充疗法.

科学领域:

神经学
免疫学
内分泌学

背景情况:

维生素D缺乏与多发性硬化症 (MS) 的风险和活动有关.
关于补充维生素D治疗多发性硬化症的好处存在矛盾.

研究的目的:

评估高剂量胆醇 (维生素D3) 作为单一疗法,以减少临床隔离综合征 (CIS) 患者的疾病活性.

主要方法:

这是一项为期24个月的随机双盲,安慰剂对照试验 (D-Lay MS),涉及316名CIS患者.
参与者每两周接受10万IU口服胆醇或安慰剂.

主要成果:

与安慰剂相比,维生素D补充剂显著降低了整体疾病活性 (60. 3% vs 74. 1%) 和MRI检测到的活性 (损伤).
维生素D组与安慰剂组之间没有明显的复发率差异.

结论:

在CIS和早期复发性复发性多发性硬化症患者中,高剂量胆醇有效降低了疾病活性.
需要进一步研究脉冲高剂量维生素D作为MS的辅助疗法.

Role of Vitamins in Maintaining Bone Health

Role of Vitamins in Maintaining Bone Health

The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
