Br J Nutr:长期补充小剂量叶酸与高血压患者血清tHcy降低之间的关系

2019-10-20 不详 网络

本研究旨在使用中国卒中一级预防试验(CSPPT)的数据来探究长期低剂量叶酸补充与高血压患者血清总同型半胱氨酸(tHcy)降低之间的关系。研究共包括16867名参与者,记录了患者基线和出诊时关于tHcy测量的完整数据。经过4.5年的中位治疗期后,叶酸治疗使患者tHcy的水平显著降低了1.6μmol/l(95%CI 1.4, 1.8)。更重要的是,校正基线tHcy和其他重要的协变量之后,在某些亚组中观

本研究旨在使用中国卒中一级预防试验(CSPPT)的数据来探究长期低剂量叶酸补充与高血压患者血清总同型半胱氨酸(tHcy)降低之间的关系。

研究共包括16867名参与者,记录了患者基线和出诊时关于tHcy测量的完整数据。经过4.5年的中位治疗期后,叶酸治疗使患者tHcy的水平显著降低了1.6μmol/l(95%CI 1.4, 1.8)。更重要的是,校正基线tHcy和其他重要的协变量之后,在某些亚组中观察到tHcy水平更大程度的降低:男性,亚甲基四氢叶酸还原酶(MTHFR)677TT基因型,更高的基线tHcy水平(≥12.5(中位数)v. <12.5μmol/l),较低的叶酸水平(<8.0(中位数)v. ≥8.0 ng/ml),估算肾小球滤过率(eGFR)<60 ml/min每1.73平方米(v. 60- <90 ml/min和≥90 ml/min每1.73平方米),既往吸烟者和同时使用利尿剂者(P均<0.05)。

综上所述,该研究结果表明,长期补充叶酸降低tHcy水平的程度与患者的性别,MTHFR C677T基因型,基线叶酸,tHcy,eGFR水平和吸烟状况密切相关。
