Crit Care Med:念珠菌感染预防用药能否降低ICU患者死亡率和后续感染率?

2017-11-21 王淳 环球医学

2017年11月,发表在《Crit Care Med》上的一项系统评价和Meta分析,考察了抗真菌预防用药对具有免疫能力的危重成年患者死亡率和后续感染的影响。研究结果表明:全身性念珠菌感染的抗真菌预防不能降低具有免疫能力的危重成年患者的死亡率,但可降低继发真菌感染率,研究存在显著的发表偏倚。

目的:本研究旨在识别出抗真菌预防对具有免疫能力的危重成年患者死亡率和后续感染的影响。

数据来源:在对比任何抗真菌药使用vs安慰剂预防ICU患者念珠菌感染的随机对照试验中,开展系统评价和荟萃分析。

研究筛选:在PubMed、Embase、Scopus、主要会议论文集、ClinicalTrials.gov以及参考文献中开展检索,

数据提取:主要结局是死亡率和侵袭性念珠菌感染。次要结局是治疗后白色念珠菌感染率和非白色念珠菌菌株率。对于所有结局,使用随机效应模型和敏感性分析,结果以风险比及95%CIs表示。

数据拟合:19项试验(10项氟康唑,4项酮康唑,1项伊曲康唑,3项米卡芬净,1项卡泊芬净)包括2792名患者被识别出。没有单个的试验显示死亡率下降。联合分析显示预防性抗真菌不能降低死亡率(风险比RR,0.88;95%%CI,0.74-1.04;p=0.14),但能显着降低50%的继发真菌感染(风险比RR,0.49;95%CI,0.35-0.68;p=0.0001)。治疗期间未观察到非白色念珠菌菌株有所增加(风险比,0.62;95%CI,0.19-1.97;p=0.42)。但是,发表偏倚排除了感染预防用药的任何明确结论。

结论:全身性念珠菌感染的抗真菌预防不能降低具有免疫能力的危重成年患者的死亡率,但可降继发真菌感染率。但是存在显着的发表偏倚。

Rev Inst Med Trop Sao Paulo:HIV感染者携带念珠菌或与其牙周病相关

大部分艾滋病毒感染者会出现念珠菌相关的临床口腔病变。研究表明,无症状念珠菌口腔定植可能导致口腔病变或成为播散性感染的来源。本研究旨在验证牙周状况对艾滋病感染及非感染者口腔念珠菌感染的影响。研究共纳入25名未感染HIV的患者和48名HIV感染者,按牙周状况分类为牙周健康和牙周病患者。根据口腔冲洗液鉴定念珠菌感染与否。对HIV感染者血液中的病毒载量和CD4+T淋巴细胞进行计数。结果,与HIV状态或牙周

含果糖的食物可以预防念珠菌病的发生

目前已经明确白念珠菌与糖尿病之间存在关联,但是其具体关联尚未完全阐明。本研究旨在评估在葡萄糖和果糖不同浓度的情况下白色念珠菌的生长率(CA),而葡萄糖和果糖是糖尿病患者的两个主要的病理生理和营养相关的糖,以更好的了解糖尿病患者营养获取策略及其与高血糖状态的关系。使用流式细胞仪探究不同浓度的葡萄糖和果糖(1000 mg%, 500 mg%, 250 mg% 和100 mg% w/v)对CA生长速率的

J Dent Res:混合念珠菌种属生物膜应对抗真菌治疗时的动力学分析

念珠菌可以引起口腔感染,它是最常见的可分离出来的人真菌病原体,多与生物被膜相联系。虽然白色念珠菌是鹅口疮患者口腔的优势生物体,但由非白色念珠菌(包括:光滑念珠菌、都柏林念珠菌和热带念珠菌)引起的生物被膜口腔定殖和感染的发生率却在不断增高,而这些种属对抗真菌治疗通常具有更强的耐药性。目前,对单种属念珠菌生物膜的研究已经取得了一定的进展,但是对混合念珠菌种属的动力学分析以及它们在应对抗真菌治疗时的动力

mSphere:椰子油对念珠菌感染有效!

马萨诸塞州塔夫斯大学的Carol Kumamoto教授进行了一项研究表明:椰子油对念珠菌属真菌感染有效!该成果发表在mSphere。她和她的同事提到:“免疫力低下或受损的如癌症患者、器官移植患者等,白色念珠菌常会从肠道进入血压,导致致命性感染,影响肾、肝、脾、肺、大脑和心瓣膜等,严重威胁生命安全。约有一半的系统性白色念珠菌感染患者会死亡!”Kumamoto教授补充到:“念珠菌是住院病人中血液感染最

尿路感染的抗真菌治疗,这几点一定要注意!

念珠菌尿路感染可能仅有脓尿而无其他临床症状,也可有典型的泌尿系感染的表现。念珠菌是尿培养中第3位常见病原体,约占所有送检中段尿标本的10%,其中白念珠菌占50%~70%,光滑念珠菌约占20%,其次为热带念珠菌、近平滑念珠菌等。存在念珠菌尿的患者多数无症状,其尿中检出念珠菌可能为标本污染或仅为膀胱、尿路导管生长的定植菌,一般不须治疗。如出现症状则根据患者情况进行个体化处理。临床4大类型局限于尿路的念
