与单一治疗相比,对抗卡巴因耐药阿尼菌 (CRAB) 感染的组合抗生素治疗没有改善30天的存活率. 需要进一步的随机对照试验来证实这些发现用于CRAB管理.
科学领域:
- 传染性疾病 传染性疾病
- 抗微生物耐药性 抗微生物耐药性
- 临床药理学 临床药理学
背景情况:
- 国际指导方针提倡在严重的抗卡巴胺耐药阿辛托巴克特 (CRAB) 感染中进行联合抗生素治疗.
- 可用的组合选项包括高剂量的硫巴克坦,多胺,四环素和 cefiderocol.
- 支持CRAB联合治疗的前性数据有限.
研究的目的:
- 为了比较CRAB感染患者的组合治疗和单一治疗之间的30天死亡率.
- 评估CRAB血流感染和呼吸机相关肺炎的联合抗生素策略的有效性.
主要方法:
- 对患有CRAB细菌性病,呼吸机相关肺炎 (VAP) 或两者兼有的患者进行了回顾性分析.
- 将患者分为单疗法或组合疗法组的分类.
- 逆概率治疗权重 (IPTW) 使用倾向性得分来平衡30天死亡率的比较.
主要成果:
- 在161名患者中,70%接受单一治疗,30%接受组合治疗.
- 总体30天死亡率为62%,组合疗法 (63.3%) 和单疗法 (60.7%) 之间没有显著差异.
- 在IPTW分析中,两组之间30天死亡率没有统计学上显著的差异 (p=0.47).
结论:
- 这项观察性研究发现,对于CRAB感染的组合治疗和单疗法之间的30天死亡率没有显著差异.
- 对CRAB感染的组合疗法需要进一步调查.
- 随机对照试验是必要的,以最终评估组合治疗在管理CRAB感染中的作用.
