Lancet:促红细胞生成素不能起到保护神经细胞的作用

促红细胞生成素可能有保护神经细胞的效果。在这项试验中,研究人员研究了其对神经功能恢复,死亡率以及创伤性脑损伤患者静脉血栓事件的影响。

该创伤​​性脑损伤(EPO-TBI)中的促红细胞生成素试验是一项双盲,安慰剂对照试验,在七个国家(澳大利亚,新西兰,法国,德国,芬兰,爱尔兰)的29个中心(所有大学附属教学医院)进行。内脑损伤后24小时之内的606例患者通过一个隐蔽的网络的计算机生成的随机化时间表随机分配接受每周一次的红细胞生成素(40000个单位皮下注射)或安慰剂(0.9%氯化钠皮下注射),每周最多三个剂量。随机分组是由创伤性脑损伤程度(中度VS重度)进行分层的。除指定的站点药剂师,所有站点的给药护士和法国的中心药房的药剂师,所有的研究人员,病人和病人的亲属都不知道治疗分配。主要成果是在6个月时通过改良的意向性治疗分析评估,患者的神经功能状态有所改善,概括为患者的扩展格拉斯哥预后量表(GOS-E)为1-4的比例降低(死亡,植物人,以及重度残疾)。2个等分预先计划的中期分析都已完成(在404名202名参与者被纳入后)。

在2010年5月3日和2014年11月1日之间,606例患者随机分配到接受促红细胞生成素(n= 308)或安慰剂(n=298)。这些患者中的10例患者在6个月时失去随访(促红细胞生成素组中的6例,安慰剂组中的4例);因此,596名患者的主要结果分析数据是可用的(促红细胞生成素组中的302例,安慰剂组中的294例)。与安慰剂相比,促红细胞生成素没有减少GOS-E评分1-4级的患者比例(促红细胞生成素组中的134例[44%] VS 安慰剂组中的132例[45%];相对风险[RR] 0.99 [95%Cl 0.83-1.18],p=0.90)。在安全性方面,促红细胞生成素没有显著影响6个月死亡率 vs 安慰剂(促红细胞生成素组305名患者中的32例患者死亡[11%] vs 安慰剂组中297例患者中的46例[16%];RR 0.68 [95%Cl 0.44-1.03],P=0.07),或增加下肢深静脉血栓的发生率(48/305[16%] vs 54/298[18%];RR 0.87 [95%Cl 0.61-1.24],P=0.44)。

对于中度或重度颅脑损伤,促红细胞生成素并没有减少重症患者的神经功能障碍(GOS-E 1-4级)的数量或增加下肢深静脉血栓的发生率。促红细胞生成素对死亡率的影响仍存在不确定性。

上海瑞金医院陈晓农:从KDIGO贫血指南谈CKD贫血治疗策略

    自1989年美国食品与药物管理局(FDA)批准促红细胞生成素(ESA)上市以来,ESA已成为CKD透析和非透析患者贫血的常规治疗药物。     能通过纠正肾性贫血而延缓CKD进展,减少CKD患者的心血管并发症、改善患者生活质量、延长患者生存期。然而,在临床实践中,ESA的使用存在地区、医师间实际操作和认识的不同,使得肾性贫血的治

美国内科医师学会(ACP)于近日公布了心脏病患者贫血和铁缺乏治疗指南。此项指南以贫血和铁缺乏英文文献为基础,评估转归包括死亡、住院、运动耐量、生活质量和心血管事件(心梗、充血性心衰加重、心律失常或心源性死亡),以及包括高血压、静脉血栓栓塞事件和缺血性脑血管事件在内的损害。以下为两项摘要中的推荐: 推荐1: 在冠心病住院患者中,ACP推荐应用限制性红细胞输注策略(血红蛋白触发阈值为7~

FASEB J:促红细胞生成素(EPO)或许能促发机体运动

在药企不断开发出安全的减肥药的大背景下,近日,一项新的研究报告称,他们从一个全新的角度:如果有一丸,能使你运动更加卖力那或许是件非常奇妙的事。这可能听起来很奇怪,但这项发表在FASEB杂志上的报告表明,这一设想是有可能实现的。瑞士研究人员发现,当小鼠脑中促红细胞生成素(EPO)升高时,它们会更加主动地去运动。此外,这些实验中使用的促红细胞生成素并没有提高红细胞计数。 瑞士苏黎世大学兽医生理学研究

慢性肾脏病透析患者肾性贫血的C.E.R.A疗法新近进展

  由上海交通大学医学院等单位最近发布的一项研究显示,在接受促红细胞生成素(EPO)治疗的慢性肾脏病(CKD)透析贫血患者中,换用持续性促红细胞生成素受体激活剂(C.E.R.A.)进行每四周一次的皮下注射可有效维持患者的血红蛋白(Hb)水平,其疗效不逊于EPO-β治疗,且患者对于C.E.R.A皮下注射耐受良好。此研究成果发表于今年7月份的《中华内科杂志》上。     研究者为观察每四
