【摘要】:研究背景: 随着科学和社会的发展、人类平均寿命的延长,终末期肾病(ESRD)患者的数量与日俱增,患病率远超于人们的想象。当慢性肾脏病(CKD)患者肾小球滤过率(GFR)<15ml/min/1.73m2时,进入终末期肾脏病阶段,需实行肾脏替代治疗,现有的主要治疗方法有血液透析(HD)、腹膜透析(PD)和肾移植术(RT)。在慢性肾脏病进展的过程中,随着GRF的下降,ESRD各种并发症的出现率逐渐升高。心脑血管并发症是ESRD患者最严重的合并症,ESRD与心脑血管并发症之间存在明显的相关性,二者相互影响,,相互促进。随着病情的进展,心脑血管并发症成为ESRD患者首要的死亡原因。血清胱抑素C(Cys C)是一种低分子量的碱性分泌型蛋白,以往的研究认为血清Cys C是反应GFR最好的内源性标志物。近年来国内外的研究发现血清Cys C与心脑血管并发症的发生有着密切的关系,血清中高水平的Cys C与左心结构和功能病变程度有明显相关性。目前,针对普通人群和老年人群血清Cys C与心脑血管疾病的研究较多,证实血清Cys C可作为预测心脑血管事件的影响因子,但对ESRD患者血清Cys C与心脑血管并发症之间的相关研究报道较少。因此,本文探讨血清Cys C与ESRD患者并发心脑血管疾病的相关性,为ESRD患者心脑血管并发症的早期预防和治疗提供可参考的依据。 目的: 监测ESRD患者血清Cys C水平,分析其与心脑血管并发症的相关性,并进一步研究不同治疗方式如非透析、HD和PD对血清Cys C的影响,早期预防并治疗ESRD患者心脑血管并发症,从而提高ESRD患者的生活质量和生存率。 方法: 采用横断面研究,选择在吉林大学第一医院二部肾内科住院患者125例,所有研究对象均明确诊断为ESRD(GFR<15ml/min/1.73m2),根据是否已接受血液净化治疗以及净化方式分为:非透析组、HD组、PD组。分别记录患者的年龄、性别、原发病,血肌酐(Scr)、尿素氮(BUN)、胱抑素C(Cys C)、血红蛋白(Hb)等生化指标,并计算肾小球滤过率(GFR),分析血清Cys C与ESRD患者生化指标以及心脑血管并发症之间的相关性。 结果: 1、125例ESRD患者87.2%合并心脑血管并发症,其中有心脑血管并发症组患者血清Cys C水平明显高于无心脑血管并发症组。 2、125例ESRD患者在不同治疗组中,HD组心脑血管并发症的发病率最高,达92.7%,其次是PD组,非透析组最低;不同治疗组血清Cys C水平分别为:非透析组5.62mg/L,HD组7.87mg/L,PD组6.92mg/L,其中HD组血清Cys C水平最高,非透析组最低。 3、109例合并心脑血管并发症患者:血清Cys C和血清SCr水之间为正相关性,与GFR呈负相关;根据不同治疗情况分组:非透析组血清Cys C和BUN、SCr、P之间均为正相关,和GFR之间为负相关;HD组血清Cys C和其他指标之间均无显著相关性;PD组血清Cys C和SCr之间为正相关,和GFR之间为负相关。 4、采用Logistic回归分析显示:血清Hb是发生心脑血管并发症的保护因素,SCr、Cys C、P是发生心脑血管并发症的危险因素。 结论: 1、ESRD合并心脑血管并发症组患者血清Cys C水平明显高于无心脑血管并发症组。 2、ESRD患者HD组和PD组患者血清Cys C水平高于非透析治疗组。 3、ESRD患者血清Cys C可以作为预测心脑血管并发症的指标。
[Abstract]:Background of Study :
With the development of science and society , the increase of the average life expectancy and the increasing of the number of patients with end - stage renal disease ( end - stage renal disease ) are more than that of people . In the course of progression of chronic kidney disease , there is a significant correlation between serum Cys C and cardiovascular and cerebrovascular diseases .
Purpose :
To monitor the level of serum Cys C in patients with non - HD , analyze its correlation with cardiovascular and cerebrovascular complications , and further study the effects of different treatments such as non - dialysis , HD and PD on serum Cys C , early prevention and treatment of cardiovascular and cerebrovascular complications in patients with end - of - heart disease , thereby improving the quality of life and survival rate of patients with patients with patients .
Method :
A cross - sectional study was conducted to select 125 patients who were hospitalized in the first hospital of Jilin University . All the subjects were diagnosed as non - dialysis ( GFR < 15ml / min / 1.73m2 ) and divided into non - dialysis group , HD group and PD group .
Results :
The serum Cys C level in the patients with cardiovascular and cerebrovascular complications was significantly higher than that in the group without cardiovascular and cerebrovascular complications .
The incidence of cardiovascular and cerebrovascular complications in HD group was the highest in group 2 and 125 patients in HD group , up to 92.7 % , followed by PD group and lowest in non - dialysis group .
