NEJM:维持性血液透析患者静脉铁输注方案比较研究

2018-10-30 zhangfan MedSci原创

研究认为,对于接受血液透析的患者中,主动给予大剂量的铁剂治疗不能有效的降低患者心血管事件发生,但可减少促红细胞生成素的用量

静脉铁输注是血液透析患者的标准治疗方案,但该方法临床有效性比较研究数据十分有限。

近日研究人员开展多中心盲终点研究,接受维持性血液透析的成年患者,随机接受高剂量铁蔗糖静脉注射(每月400mg,直至铁蛋白浓度>700μg/L转铁蛋白饱和度为≥40%)或低剂量铁蔗糖静脉注射(当铁蛋白浓度<200μg/升或转铁蛋白饱和度<20%时,每月给药0-400mg)。研究的主要终点为非致命性心肌梗塞、非致命性中风、心力衰竭住院或死亡的综合终点,次要终点包括死亡率、感染率和促红细胞生成素使用剂量。

2141名患者参与研究,其中高剂量组1093人,低剂量组1048人,平均随访2.1年。高剂量组月均铁剂注射264mg,低剂量组为145mg;高剂量组月均促红细胞生成素剂量为29757IU,低剂量组为38805IU。高剂量组终点事件发生率为30.5%(333例),低剂量组32.7%(343例),风险比值比为0.88。采用反复事件法分析显示,高剂量组终点事件发生456次,低剂量组为538次(HR=0.78)。组间感染率相近。

研究认为,对于接受血液透析的患者中,主动给予大剂量的铁剂治疗不能有效的降低患者血管事件发生,但可减少促红细胞生成素的用量。

终末期肾病患者如何选择透析方式?

近十多年来,无论是血液透析还是腹膜透析均在自身技术上有了突飞猛进的发展。随着研究的深入,越来越多的观察发现两种透析模式在是不同类型的终末期肾功能衰竭(ESRD)患者中疗效相差甚远。

Liver Int:慢性血液透析和肾移植患者中,隐匿性乙型肝炎病毒感染的流行率较低

研究发现,在CHD患者中,OBI的患病率为零,而KTxR患者OBI的流行率非常低(<1%),这表明在CHD人群中,不需要对HBV-DNA进行常规筛查。然而,在KTxR中,应考虑采用HBV-DNA进行移植前筛查。检测PBMCs中的HBV-DNA似乎没有额外价值。

2017年ISRNM《血液透析治疗期间饮食》专家共识解读

对2017年国际肾营养和代谢学会(ISRNM)《血液透析治疗期间饮食》专家共识中支持透析中营养支持的理由与反对透析中营养支持的理由进行解读,指出透析中营养应被视为血液透析病人标准护理实践的一部分,可提供给血流动力学稳定、无禁忌证且治疗期间无不耐受食物史的病人。 

2018 KHA-CARI指南:血液透析中心感染控制建议

2018年10月,澳大利亚肾病指南委员会(CARI)发布了血液透析中心感染控制建议指南,主要目的是针对血源性病毒感染以及透析中心多重耐药筛查和管理提供指导建议。 

维持性血透患者10大常规检查,你都知道吗?

部分血液透析患者在规律治疗情况明显好转后,即认为只要按时透析就行,没必要做一些化验检查。而实际上,却犯了一个很大的错误,因为透析并不能解决疾病本身带来的所有问题,有些问题必须应用药物去干预,而且应定期调整药方案。

JASN:血液透析患者动态血压与全因以及心血管死亡率的关系

由此可见,该研究为外周动态SBP或PP与血液透析患者死亡率之间存在的U形关联提供了证据。此外,它表明潜在的心脏疾病可以解释相反方向的相关性。
