概括

便微生物移植 (FMT) 现在是复发性Clostridioides difficile感染 (rCDI) 的关键治疗方法. 美国食品和药物管理局批准的疗法和研究产品对rCDI和其他疾病具有前景.

科学领域:

微生物学
胃肠病学
传染性疾病

背景情况:

便微生物移植 (FMT) 已成为复发性Clostridioides difficile感染 (rCDI) 的主要治疗方法.
抗生素耐药性C. difficile菌株的出现增加了FMT的相关性.
目前有两种基于微生物群的标准化疗法,即RebyotaTM和VowstTM,已获得FDA的批准,用于预防rCDI.

研究的目的:

提供FDA批准的用于预防rCDI的微生物群衍生疗法.
审查研究中的微生物产品的数据,包括依赖于供体和独立于供体的选择.
总结目前关于常规FMT的证据,以超越rCDI预防.

主要方法:

对支持传统FMT和FDA批准的FMT有效性和安全性的关键试验的审查.
对VE303和NTCD-M3等实验生物治疗产品 (LBPs) 的数据进行分析.
在严重的CDI和非传染性条件下进行常规FMT的证据摘要.

主要成果:

美国食品和药物管理局批准的FMT和传统FMT在特定的rCDI群体中显示持续反应率超过80%.
作为独立于捐赠者的替代品,正在开发研究中的LBP.
常规的 FMT 越来越多地用于严重的 CDI,并研究非传染性疾病.

结论:

虽然全球实践各不相同,但FDA批准的FMT在rCDI治疗方面是一个显著的进步.
进一步的临床试验对于以微生物群为基础的疗法治疗各种疾病的量身定制方法至关重要.
微生物群衍生生物和LBP的调控途径正在不断发展.

What is Monogastric Digestion?

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
