Am J Clin Nutr:补充维生素D会不会增加肾结石风险?

2016-09-13 Mechront 译 MedSci原创

关于维生素D补充剂的随机对照试验(RCT)现在是越来越多,并且试验中维生素D补充剂的剂量也是越来越高。已经有2项RCT试验表明,每年大剂量补充维生素D会导致不良事件;当然,也有RCT试验表明,补充低剂量维生素D+钙,会增加肾结石的风险。 我们对维生素D补充剂(干预组) vs 安慰剂组(对照组)(≥24周)的RCT试验数据进行了分析,调查了钙代谢相关副作用,尤其是高钙血症、高钙尿症、肾结石。通

关于维生素D补充剂的随机对照试验(RCT)现在是越来越多,并且试验中维生素D补充剂的剂量也是越来越高。已经有2项RCT试验表明,每年大剂量补充维生素D会导致不良事件;当然,也有RCT试验表明,补充低剂量维生素D+钙,会增加肾结石的风险。

我们对维生素D补充剂(干预组) vs 安慰剂组(对照组)(≥24周)的RCT试验数据进行了分析,调查了钙代谢相关副作用,尤其是高钙血症、高钙尿症、肾结石。通过检索Ovid Medline (PubMed)、EMBASE、Cochrane Library等数据库,一共纳入了48项研究、涉及19833例参与者,对其进行数据合并荟萃分析。

只有9项试验有肾结石相关报告,且干预组肾结石发生率低于对照组,不过不具有统计学意义(RR: 0.66, 95% CI: 0.41, 1.09; P = 0.10)。

37项研究数据表明,干预组 vs 对照组,参与者高钙血症风险增加(RR: 1.54; 95% CI: 1.09, 2.18; P = 0.01)。

14项研究数据表明,干预组 vs 对照组,参与者高钙尿症风险增加(RR: 1.64; 95% CI: 1.06, 2.53; P = 0.03)。

亚组分析表明,维生素D补充剂对高钙血症、高钙尿症、肾结石风险的影响,与基线25羟维生素D、维生素D剂量和持续时间或同时补充钙等因素无关。

结果表明,长期补充维生素D可能会导致高钙血症和高钙尿症的风险增加;但并不会增加肾结石的风险。还需要大型的随机对照试验来证实这些发现。
