JCEM:血浆维生素D代谢物与2型糖尿病的关联

2018-11-12 xing.T MedSci原创

由此可见,血浆非差向异构体25(OH)D3与T2D呈负相关,其与产生总25(OH)D的主要代谢物相一致。25(OH)D3的差向异构体与T2D之间的正相关性为评估维生素D差向异构化和维生素D亚型在糖尿病病因学中的生物学相关性提供了新信息。

维生素D状态与2型糖尿病(T2D)之间前瞻性相关性的现有证据几乎完全集中于循环中总25-羟基维生素D [25(OH)D]水平,而不区分其亚型:非差向异构体和差向异构体25(OH)D3立体异构体;以及25(OH)D2、25(OH)D的最小成分。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,研究人员的目的是调查循环中总的和这三种代谢物中的每一种的水平与T2D事件之间的前瞻性关联。

在针对T2D的EPIC-InterAct病例队列研究纳入了9671例T2D患者和13562例亚组成员。通过液相色谱质谱法来定量血浆维生素D代谢物。研究人员使用多变量Prentice加权Cox回归来估计每种代谢物与T2D的风险比(HRs)。分析在国家内单独进行,并使用随机效应荟萃分析在各国进行估算。

总25(OH)D、非差向异构体25(OH)D3、差向异构体25(OH)D3和25(OH)D2的平均浓度(标准差)分别为41.1(17.2)、40.7(17.3)、2.13(1.31)和8.16(6.52)nmol/L。血浆总25(OH)D和非差向异构25(OH)D3与T2D呈负相关[两个变量的多变量调整HR/SD=0.81(95%CI为0.77-0.86)],而非差向异构25 (OH)D3与其呈正相关:每1个SD的HR=1.16(1.09-1.25)。对于25(OH)D2 ,则与T2D无统计学显著的相关性[每1个SD的HR=0.94(0.76-1.18)]。

由此可见,血浆非差向异构体25(OH)D3与T2D呈负相关,其与产生总25(OH)D的主要代谢物相一致。25(OH)D3的差向异构体与T2D之间的正相关性为评估维生素D差向异构化和维生素D亚型在糖尿病病因学中的生物学相关性提供了新信息。
