摘要 目的探讨慢性肾脏病(CKD)患者血浆非活性形式非羟化基质γ羧基谷氨酸蛋白(dp-ucMGP)的检测及意义。方法检测120例CKD分级为2。5D级患者血浆dp-ucMGP水平,并接受多层螺旋CT扫描量化主动脉钙化情况,对患者的病死率进行前瞻性研究。结果随着CKD分级进展,患者血浆dp-ucMGP水平逐步增加,2-3级、4-5级和5D级CKD患者血浆dp-ucMGP水平比较差异有统计学意义(P〈0.05)。CKD分级、血红蛋白、CT计分、C反应蛋白、年龄和香豆素应用与血浆dp-ucMGP水平具有独立相关性。此外,血浆dp-ucMGP水平和年龄与CT计分呈正相关。随访(712±411)d,死亡38例(其中23例为心血管事件)。初步分析显示,血浆dp-ucMGP≥915pmol/L与总病死率具有相关眭;但是经年龄和CT计分校正后其相关性消失。结论随着CKD分级进展,患者血浆dp-ucMGP水平逐步增加,且与严重的主动脉钙化相关。血浆dp-ucMGP可以作为CKD患者血管钙化的客观指标。
