维生素D缺乏症是所有年龄组的全球健康问题,尤其是老年人。血清25(OH)D是评价维生素D营养状况的生物标志物。然而,游离激素假说提出,游离维生素D可能是维生素D营养状况的更可靠标志物。因此,本研究的目的是(1)评估老年人中游离25 OHD的分布,(2)评估老年人群中游离25 OHD与总25(OH)D、1,25(OH)2D、24,25(OH)2D、钙(Ca)、碱性磷酸酶(ALP)和磷(P)之间的相关性。本研究共招募了312名健康老年人,并采集了残留血清样本。使用LC-MS/MS测量游离25 OHD、总25(OH)D、24,25(OH)2D和1,25(OH)2D。使用自动分析仪测量其他生化分析物。结果表明,随着总25(OH)D水平的升高,25(OH)D3、1,25(OH)2D、24,25(OH)D和游离25 OHD水平升高,而25(OH)D/24,25(OH)2D水平降低。此外,我们观察到游离25 OHD水平与总25(OH)D水平显著正相关,(r= 0.226,P < 0.001),25(OH)D 24,25(OH)2D(r = 0.231,P <0.001),但与25(OH)D/24,25(OH)2D呈负相关(r=-0.185,P < 0.01)。25(OH)D、25(OH)D3、24,25(OH)2D和25(OH)D/24,25(OH)2D与1,25(OH)2D具有相关性。血清游离25 OHD与肌酐(Cr)呈正相关(r= 0.227,P <0.001)。我们的结果表明,一个更窄的分布,游离25 OHD比直接测量技术的报告,并证实了游离25 OHD和总25(OH)D之间的相关性。
Vitamin D deficiency is a global health problem in all age groups, especially in the elderly population. Serum 25(OH)D is the biomarker to assess vitamin D nutrition status. However, the free hormone hypothesis proposes that free vitamin D might be a more reliable marker of vitamin D nutrition status. Thus, the aims of this study were to (1) evaluate the distribution of free 25OHD in elderly individuals, and (2) to assess the association between free 25OHD and total 25(OH)D, 1,25(OH)2D, 24,25(OH)2D, calcium (Ca), alkaline phosphatase (ALP), and phosphorus (P) in elderly population. A total of 312 healthy elderly individuals were enrolled in this study and residual serum samples were collected. Free 25OHD, total 25(OH)D, 24,25(OH)2D, and 1,25(OH)2D were measured using LC-MS/MS. Other biochemical analytes were measured using automatic analyzers. Our results showed that with an increase in the levels of total 25(OH)D, the levels of 25(OH)D3, 1,25(OH)2D, 24,25(OH)D, and free 25OHD increased, whereas the levels of 25(OH)D/24,25(OH)2D decreased. Further, we observed that the level of free 25OHD was significantly positively correlated with the total 25(OH)D (r= 0.226, P < 0.001), 25(OH)D (r= 0.221, P < 0.001), and 24,25(OH)2D (r= 0.231, P < 0.001) but was negatively correlated with 25(OH)D/24,25(OH)2D (r= -0.185, P < 0.01). Moreover, the total 25(OH)D, 25(OH)D3, 24,25(OH)2D, and 25(OH)D/24,25(OH)2D were correlated with 1,25(OH)2D. Furthermore, free 25OHD was positively correlated with creatinine (Cr) (r= 0.227, P <0.001). Our results showed a narrower distribution for free 25OHD than that reported by direct measurement techniques and confirmed the correlation between free 25OHD and total 25(OH)D.
