Am J Kidney Dis:C-反应蛋白可预测终末期肾病风险

2016-11-26 haofan MedSci原创

伴有贫血和CKD的2型糖尿病患者CRP基础水平升高很是常见,并且与将来发展为终末期肾病以及死亡或终末期肾病的复合结局相关。

为了更好地了解升高的C-反应蛋白(CRP)水平与慢性肾脏病(CKD)进展之间的潜在相关性,最近,肾脏病领域权威杂志Am J Kidney Dis上发表了一篇来自美国波士顿布莱根妇女医院肾内科的Finnian R. Mc Causland医生及其研究团队的文章,旨在评估CRP水平与终末期肾脏疾病(ESRD)发展之间的关系。

该研究是以用Aranesp治疗减少心血管事件试验(TREAT)为基础,研究人员对这项随机对照试验进行事后分析。该研究的参与者为来自TREAT研究中的4038例2型糖尿病伴有CKD和贫血患者,其预测指标为血清C反应蛋白的基础浓度。主要终点事件为终末期肾病的发生;次要终点事件包括血清肌酐倍增、终末期肾病/血清肌酐加倍复合指标,以及死亡或终末期肾病复合结局。研究者采用未调整和调整的Cox回归模型来评估CRP基础水平与发生感兴趣结局所需时间的关系。

这项研究中的参加者平均年龄为67岁,43%为男性,64%为白种人,大约一半(48%)的患者CRP水平>3 mg/L;668名参与者发展为ESRD,1270名参与者发生死亡或终末期肾病的复合结局。与CRP基础水平≤3 mg/L的患者相比,那些CRP水平中度/显著升高(≥6.9 mg/L;24%的患者)的患者有较高的调整后的终末期肾病的风险(风险比为1.32;95%可信区间为1.07-1.63)和死亡或终末期肾病的复合结局(风险比为1.41;95%可信区间为1.21-1.64)。在竞争风险模型中,虽然结果不显著,但可见到相似的趋势。

由此可见,伴有贫血和CKD的2型糖尿病患者CRP基础水平升高很常见,并且与将来发展为终末期肾病以及死亡或终末期肾病的复合结局相关。
