J Hypertens:神经肽Y可预测慢性肾病患者的心血管事件

2019-01-11 xing.T MedSci原创

由此可见,NPY是透析前CKD患者心血管事件的独立且稳健的预测因素,并且这些事件的风险在年轻患者中是最大的。这些研究结果表明,NPY可能在该人群中心血管疾病的高风险中发挥者重要作用。

神经肽Y(NPY)是一种具有种效应的交感神经递质,可调节血管调控反射功能、心肌细胞生长、炎症和先天免疫。循环NPY水平可预测接受透析的终末期肾病患者血管死亡率,但这种关系从未在透析前慢性肾病(CKD)患者中进行过评估。

近日,高血压领域权威杂志Journal of Hypertension上发表了一篇研究文章,研究人员调查了循环NPY与心血管事件风险之间的关系(精细和灰色竞争风险模型),研究人员对753名2-5期CKD患者进行了中位数为期36个月的随访。

研究人员发现独立于其他危险因素,血浆NPY水平与肾小球滤过率直接相关(β=-0.19,P<0.001),但与血清IL6和C反应蛋白确定的全身炎症无关。随访期间112例患者发生心血管事件,12例患者死亡。在对传统危险因素和大量CKD特异性危险因素进行充分调整的分析中,并将死亡视为竞争事件(精细和灰色模型),NPY增加0.25μmol/ l,可有力预测心血管事件的事件风险(亚群风险比为1.25; 95%置信区间为1.09-1.44; P=0.002)。此外,经过充分调整的NPY与心血管结局之间的关系随着年龄的增长而变化(P=0.012),在年轻患者中相当强,但在老年患者中则较弱。

由此可见,NPY是透析前CKD患者心血管事件的独立且稳健的预测因素,并且这些事件的风险在年轻患者中是最大的。这些研究结果表明,NPY可能在该人群中心血管疾病的高风险中发挥者重要作用。
