Clin Exp Allergy:血清25-羟基维生素D水平与过敏性鼻炎、过敏性致敏和非过敏性鼻炎之间无关联

之前的观察性研究没有发现血清25-羟维生素D(25(OH)D)水平与过敏性鼻炎(AR)或过敏性致敏(AS)之间有结论性的关联。最近,有研究人员采用双样本孟德尔随机化(MR)方法,调查了25(OH)D水平与AR和AS风险之间的因果关系。

研究人员将之前显示与血清25(OH)D水平相关的7个单核苷酸多态性(SNPs)定义为工具变量。主要结果是AR,次要结果是AS和非过敏性鼻炎(NAR)。结果的全基因组关联(GWA)汇总统计来自两个队列研究(EAGLE联盟和英国生物库)。研究发现,血清25(OH)D水平与AR(OR:0.960;95%CI:0.779-1.184)、AS(OR:1.059;95%CI:0.686-1.634)或NAR(OR:0.937;95%CI:0.588-1.491)的风险无因果关系。亚组分析也显示25(OH)D合成相关SNPs与结果之间也无相关性。敏感性分析也得出了类似结果。

最后,研究人员指出,这项MR研究没有发现支持欧洲血统人群中血清25(OH)D水平与AR、AS和NAR风险之间存在因果关系的证据。他们的结果反驳了以往补充维生素D可有效预防过敏性疾病的假设。
