抗生素可以通过破坏有益的肠道微生物并促进耐药病原体生长来引起二次感染. 本综述探讨了这些风险和减轻抗生素相关感染的策略.
科学领域:
- 微生物学 微生物学
- 传染性疾病 传染性疾病
- 药理学 药理学是指药理学的学科.
背景情况:
- 抗生素对于治疗细菌感染至关重要,但可能会损害患者的居住微生物群.
- 开始性微生物的破坏降低了殖民抵抗力,增加了对新感染的易感性.
- 抗生素的使用可以选择和超越微生物群中已经存在的耐药病原体.
研究的目的:
- 审查抗生素治疗促进后续感染的机制.
- 讨论降低殖民抗性和抗性微生物过度生长的双重风险.
- 为突出减轻抗生素相关感染的策略.
主要方法:
- 对抗生素对宿主相关微生物群落的影响的文献综述.
- 分析将抗生素使用与感染风险联系在一起的机制.
- 在各种身体部位和病原体中合成了抗生素相关感染的例子.
主要成果:
- 抗生素会对微生物群造成"附带损害",损害其保护功能.
- 抗生素的选择压力可能导致难以治疗的超级感染的出现.
- 这些微生物群破坏和病原体过度生长的过程往往相互关联.
结论:
- 与抗生素相关的感染源于有益微生物的丧失和耐药病原体的过度生长.
- 了解这些相互关联的过程是管理抗生素风险的关键.
- 新的策略正在出现,以抵消抗生素诱导的附带损害和减少感染风险.
