Neurology:肾功能不全与痴呆有啥关系?

2016-12-16 haofan MedSci原创

肾功能不全与认知功能障碍或痴呆之间相关性的总体证据不强也不弱。有证据表明,蛋白尿与较高的认知障碍和痴呆症发生率相关。

已有研究表明肾功能不全与认知功能障碍和痴呆的风险增加有关,但是存在相互矛盾的研究。因此,近日,神经病学领域权威杂志Neurology上发表了一篇针对这一问题的系统评价和荟萃分析文章,旨在总结关于肾功能损害的潜在标志物与认知功能障碍或痴呆发生之间存在前瞻性相关性的最佳证据。

研究人员检索了MEDLINE、EMBASE和Cochrane系统评价数据库,搜索了2016年8月1日前所有潜在的出版文献。纳入分析的研究必须满足以下条件:以人群为基础的研究、前瞻性的设计、参与者超过100人、年龄≥45岁、随访时间超过1年以及包含了认知/痴呆结局。在适当的情况下,通过随机效应荟萃分析从而获得合并比值比(OR)和95%可信区间(CI)。

研究人员从8494篇文献中找出来了22篇符合纳入标准的研究文献。研究者发现对于蛋白尿有充分的证据,对于估计肾小球滤过率(eGFR)有混合的结果,对于胱抑素C支持证据不充足,而血清肌酐和肌酐清除率只是初步证据。研究人员对5个研究的27,805名参与者进行荟萃分析结果显示35%的白蛋白尿参与者出现认知障碍或痴呆症的风险增加(OR 1.35,95% CI1.06–1.73,P=0.015),而eGFR<60mL/min/1.73 m2与认知障碍或痴呆症的风险增加无显著相关性(OR 1.28,95% CI0.99–1.65,P=0.063)。另外没能对血清肌酐、肌酐清除率或胱抑素C进行荟萃分析。

由此可见,肾功能不全与认知功能障碍或痴呆之间相关性的总体证据不强也不弱。有证据表明,蛋白尿与较高的认知障碍和痴呆症发生率相关。

JACC:肾功不全的心肌梗死患者可应用ACEI/ARB治疗

背景:血管紧张素转换酶抑制剂(ACEI)和血管紧张素受体拮抗剂(ARB)是否应该用于急性心肌梗死(AMI)后所有患者或仅高危患者的二级预防尚有争议。目标:本研究旨在探讨AMI后,不同风险状况下(包括肾小球滤过率),ACEI/ARB治疗与良好预后的相关性。方法:瑞典的研究者评估了2006至2009期间,瑞典登记记录中AMI幸存者出院后和随访中应用ACEI/ARB的数据。应用Cox比例风险模型研究(意

肾功能不全患者,怎样选择抗菌药物?

肾脏是大部分抗菌药物及其代谢产物的主要排泄器官,在肾功能不全时容易导致这些药物在体内积聚以致发生毒性反应,尤其是肾毒性抗菌药物。因此,肾功能不全患者应用抗菌药物时,不能按常规用量给予,必须根据肾功能损害程度调整给药方案。   一、肾功能不全时抗菌药物的选用原则   ①有明确指征时方可使用;   ②根据感染的严重程度、病原菌种类及药敏试验结果等选用无肾毒性

JACC:心脏指数降低不是心衰患者肾功能不全的主要驱动因素

人们普遍认为,心脏指数(CI)降低是心脏衰竭(HF)患者肾功能不全的一个显著贡献因子。然而,最近的数据却质疑了这一看法。这项研究旨在确定接受肺动脉导管(PAC)的HF患者的CI和肾功能之间的关系。ESCAPE(充血性心力衰竭和肺动脉导管有效性评估研究)试验包含了随机或注册部分的接受PAC的患者(n=575)。研究人员评估了多个亚组中CI和肾功能之间的关联,并评估非线性,阈值和纵向关系。在CI和估计

Heart:术前肾功能不全与TAVI患者转归差相关

英国一项研究表明,在接受经导管主动脉瓣置入术(TAVI)的患者中,术前肾功能不全与包括死亡在内的转归恶化具有相关性。论文1月12日在线发表于《心脏》(Heart)。 此项研究利用TAVI登记系统前瞻性采集了3980例患者的相关数据和临床转归资料,并评估了肾功能不全与TAVI后患者转归的相关性。 结果显示,205例(5.5%)患者在住院期间死亡。即便对危险因素进行校正之后,中、重度慢

Diabetes Care:新型二甲双胍制剂可用于治疗肾功能不全的2型糖尿病患者

近日发表于 Diabetes Care一项新的研究表明,常用于治疗2型糖尿病的二甲双胍,其发挥降糖作用的部位是在肠道而非血液中,这意味着研究人员所测试的二甲双胍延释制剂可适用于40%不能服用现有二甲双胍制剂的2型糖尿病患者。二甲双胍用于2型糖尿病的治疗已近60年,尽管其用药历史悠久,但科学家们尚未准确确定二甲双胍在人体内发挥最大降糖作用的机制及部位。而来自北卡罗莱纳大学医学院的研究明确显示,正如许

“低钠盐是送命盐”之说靠谱吗?

这几天微信朋友圈里热传着一个段子:“急诊的高钾血症越来越多,追问病史,许多人都是用的低钠盐,因为低钠盐比普通盐贵,认为贵的就是好的。 肾脏科医生,天天讲,就买最便宜的雪花盐,不能买低钠盐,低钠盐就是高钾盐,是送命盐,恐怕一般的医生也不知道,或者也没有注意,只有肾脏科医生特别重视。我是觉得这个要转的!确实息息相关。超市卖的低钠无碘盐,还是不要买了,只买普通的无碘盐就好了!”许多朋友看到这个段子以后向
