这项研究表明最佳的维生素D水平:25-基维生素D的30-50 ng/mL和1,25-二基维生素D的50-70 pg/mL. 这些水平与减少炎症和平衡的矿物代谢相关.
科学领域:
- 内分泌学 在内分泌学.
- 营养科学 营养科学
- 临床生物化学 临床生物化学
背景情况:
- 对25-基维生素D (25(OH) D) 和1,25-二基维生素D (1,25(OH) 2D) 的最佳目标值进行了讨论.
- 维生素D在炎症和矿物代谢中的作用是复杂的,需要进一步阐明.
研究的目的:
- 调查维生素D代谢物 (25(OH) D和1,25(OH) 2D) 与炎症标志物之间的关系.
- 检查维生素D代谢产物与矿物代谢标志物之间的关联.
主要方法:
- 从2012年12月到2020年4月的两个大型队列 (n=455,062和n=47,778) 的数据分析.
- 利用二次模型来评估维生素D水平,炎症指标 (WBC,CRP) 和矿物代谢标志物 (酸盐,,iPTH) 之间的相关性.
- 采用多重回归分析来确认与混因子的独立性.
主要成果:
- 在炎症标志物和25(OH) D和1,25(OH) 2D之间观察到U形关系.
- 最小的炎症标志物发生在1,25(OH) 2D ~60 pg/mL和25(OH) D ~32-42 ng/mL.
- iPTH与维生素D代谢产品的逆相关性;和与维生素D代谢产品的正相关性.
- 酸产品的急剧增加超过50 ng/mL 25(OH) D,表明血管化风险.
结论:
- 拟议的目标范围:为25(OH) D提供30-50 ng/mL,为1,25(OH) 2D提供50-70 pg/mL.
- 这些范围受到减少炎症和平衡矿物代谢的关联的支持.
- 建议对临床终点进行进一步的验证.
