重复 J Antimicrob Chemot:侵袭性念珠菌病,抗真菌治疗剂量不足是通病

2018-01-26 吴星 环球医学

越来越多的证据表明,侵袭性念珠菌病治疗中抗真菌治疗常常剂量不足,尤其是危重症患者中。2018年1月,意大利科学家在《J Antimicrob Chemother》发表了侵袭性念珠菌病的抗真菌剂量的综述。

越来越多的证据表明,侵袭性念珠菌病治疗中抗真菌治疗常常剂量不足,尤其是危重症患者中。2018年1月,意大利科学家在《J Antimicrob Chemother》发表了侵袭性念珠菌病的抗真菌剂量的综述。

在过去,多数侵袭性念珠菌病的抗真菌治疗的给药建议都遵循一刀切的方法,即建议在肾或肝功能损害的前提下,降低一些抗真菌药物的维持剂量。然而,越来越多的药物代谢动力学(PK)/药效学(PD)研究已经指出,侵袭性念珠菌病治疗的抗真菌药物剂量不足已经是广泛存在的沉默流行病,尤其是重症患者或分布容积、蛋白质结合和药物清除已经发生改变的特殊人群。在本综述中,研究者探讨了目前侵袭性念珠菌病治疗的抗真菌药物剂量建议如何发生了改变,需要剂量优化或治疗药物监测新方法的特殊人群是什么,尤其在面临念珠菌抗真菌药耐药越来越多的形势下。

本综述的首要信息是,在成人患者侵袭性念珠菌病的治疗中,PK变异性是抗真菌治疗的重大问题。在过去,PK变异性对治疗结局的影响可能已经被较低的MICs最小化,棘白菌素类和三唑类耐药性的增加现在正挑战常规给药的限度。因此,应探索当前和未来抗真菌药物基于PK/PD原则的新的给药模式,类似于氨基糖甙类每日一次(不频繁)给药或β-内酰胺连续输注+可能的TDM,以将它们的有效性最大化,并保留它们对将处于侵袭性念珠菌病风险的未来患者的效用。

Sci Rep:使用Ag包裹药物可增强药物的抗菌活性

目前存在很多基于聚合物、生物材料和氧化物的药物持续释放的基质。据我们所知,目前还未有使用金属家族作为持续释放药物的基质。本研究中,研究人员研发了一种新的生物复合材料,即将镇痛药物包裹在金属银中,用于缓释药物。研究人员制备了布洛芬@Ag、萘普生@Ag、曲马多@Ag和布比卡因@Ag复合材料。研究人员还提供了金属内药物释放的详细动力学分析,表明金属确实可以作为药物释放的储存库。此外,研究人员还探究了Ag

Nanoscale Res Lett:石墨烯的抗菌性能及细胞毒性如何?

近年来,石墨烯(G)和氧化石墨烯(GO)纳米颗粒已经开始应用于手术植入物的表面修饰中。然而,G和GO的生物安全性和抗菌能力尚不清楚。在本研究中,通过与骨髓间充质干细胞(BMSCs)共同培养来评估体外G和GO的生物安全性,并通过将材料植入小鼠肌肉组织中观察生物安全性。生物安全性结果显示,10μg/ml是G和GO的安全临界浓度。当浓度超过10μg/ml时,G和GO的细胞毒性呈剂量依赖性。抗菌结果表明,

抗菌药物管理:“利剑”具有双面性 保护为善用之基

事物常具有多面性,抗菌药物也不例外。“抗菌药物是医生用于治疗、挽救病人的武器。”对抗菌药物的药用价值,国家卫生计生委医政医管局局长张宗久,在近日举行的“2017年抗菌药物合理使用宣传周”的启动仪式上,如此表示。而在抗菌药物带来的细菌耐药问题方面,国家卫生计生委医政医管局主任王曼丽介绍,2016年门诊抗菌药物患者使用率在全国总体水平达到10.3%,“抗菌药物使用强度逐步下降,这个趋势应该是稳中向好的

J Dent Res:整合抗菌物质至植入体表面的效果观察

随着关节置换、脊柱外科手术和牙齿种植的数目日益增多,目前急迫需要应对植入体相关感染的方法。除了严格的消毒,还有一种有效的可以预防破坏性并发症的方法就是生产一种新型的具有抗菌特性的植入体。重要的是,这种植入体在牙植入环境中必须具有一定的活性,因为它埋藏在富含糖蛋白的唾液流体中,而富含糖蛋白的唾液可以增强细菌粘附和传播以及生物膜的形成。然而,要设计这样一种抗菌表面,在抗菌活性和需要植入体与骨环境相互作

J Dent:一步法制备的银-玻璃离子水门汀具有优良的抗菌性能

本研究旨在(1)通过银纳米粒子(AgNP)在常规玻璃离子粘固剂(GIC)的聚丙烯酸酯溶液中一步还原成多酸制剂,赋予其抗菌活性;(2)与市售常规GIC相比评估实验离聚物的处理和机械性能。通过紫外-可见光谱在连续UV光暴露期间监测具有增加的亚化学计量的AgNO3的制剂,并通过透射电镜分析。使用包含小的和分散的球形纳米颗粒(〜6nm)合成的制剂来设计实验所用的纳米银玻璃离子粘固剂(NanoAg-GIC)

J Colloid Interface Sci:混合水凝胶不仅可载药还可抗菌

水凝胶是一种很有应用前景的3D材料,越来越多的研究发现其可作为药物和细胞载体及递送进行应用。本研究中,我们报告了一个可注射的胶体水凝胶,直接由氧化石墨烯(GO)和热敏纳米凝胶(tNG)制备。羧基和氧乙基之间的pH依赖性氢键相互作用可使得GO和纳米凝胶之间形成可逆组装。水凝胶是可塑的,可以成型为不同的形状,随着pH和温度的变化其机械强度可调。实验研究结果显示,该混合水凝胶具有较高的抗菌活性,且作为支
