AJKD:维生素B12水平对叶酸治疗与CKD病程之间相关性的影响

2019-10-20 xing.T MedSci原创

由此可见,叶酸治疗与轻度至中度CKD患者的CKD进展几率大大降低有关。

在叶酸强化或补充人群中,总同型半胱氨酸水平的主要营养决定因素是维生素B12(B12)状态。近日,肾脏病学权威杂志Am J Kidney Dis上发表了一篇研究文章,研究人员旨在评估B12水平对叶酸治疗与慢性肾脏疾病(CKD)进展之间的关联的修饰作用。

这是一项干预试验的事后分析,研究人员对中国卒中一级预防试验(CSPPT)的肾脏疾病子研究中的1374名患有高血压的轻度至中度CKD成年人进行的事后分析,在基线时对B12进行了测量,该研究在中国叶酸含量低的江苏省的20个社区中进行。这些参与者随机接受每日两次接受依那普利10 mg和叶酸0.8 mg或单独服用依那普利10mg治疗。该研究的主要结局是CKD的进展(定义为肾小球滤过率[eGFR]降低≥30%,如果基线eGFR≥60mL/min/1.73m2则降至<60mL/min/1.73m2;或者如果基线eGFR≤60 mL/min/1.73m2,eGFR降低≥50%或肾衰竭。

该研究的平均基线eGFR为86.1±20.5(SD)mL/min/1.73m2,中位治疗时间为4.4年。与单独服用依那普利相比,基线B12水平较高(≥248pmol/L)的参与者中,依那普利-叶酸治疗可使主要结局的几率降低83%(OR为0.17;95%CI为0.07- 0.40)。然而,在基线B12水平<248pmol/L(代谢性B12缺乏)的人群中,主要结局之间无显著的组间差异(OR为1.21;95%CI为0.51-2.85)。B12水平与叶酸治疗之间的相互作用很显著(P=0.001)。

由此可见,叶酸治疗与轻度至中度CKD患者的CKD进展几率大大降低有关。
