摘要: 为研究血透患者血浆总同型半胱氨酸(tHcy)浓度与动脉粥样硬化性血管并发症(AVD)的关系,选择53例维持性血透患者,按既往有无血管并发症分为动脉粥样硬化性血管疾病(AVD)组和无AVD组,采用高效液相色谱法和荧光探测仪检测血浆tHcy。结果显示:AVD组平均血浆tHcy浓度明显高于无AVD组(P<0.05);多因素逐步Logistic回归分析显示:血浆tHcy浓度升高(>37.39μmol/L)使血透患者发生AVD的危险性增加。提示:血浆同型半胱氨酸升高是血透患者发生动脉粥样硬化性血管并发症的危险因素。

Abstract: To examine if hyperhomocysteinemia was associated with atherosclerotic vascular disease in hemodialysis patients, fifty-three chronic uremic patients on regular hemodialysis treatment were studied, of which twenty-three patients had coronary or cerebral vascular disease. Total fasting plasma homocysteine concentrations were determined by HPLC with fluorescent detection. Total homocysteine level was higher in patients with cardiovascular disease than in those without(P< 0.05). In a stepwise multiple logistic regression analysis (α=0.1) to determine the independent contribution of each factor to the risk of vascular disease, only plasma total homocysteine levels showed a significant correlation in this model. Our results support the hypothesis that higher total plasma homocysteine concentration may be an independent risk factor for atherosclerotic vascular disease of hemodialysis patients.
