人類菌群移植

腸胃疾病,如艱難梭菌感染(CDI)是很危險和嚴重的。他們影響到數千名香港、以及數十萬名其他亞洲城市的患者,遭受日常症狀的痛苦。

也許你聽說過糞菌移植(FMT)。這項在2013年“新英格蘭醫學雜誌”上進行了醫學臨床試驗的研究和發表的新型臨床療法。在這項試驗中,醫生成功地治癒了16名荷蘭患有嚴重複發性艱難梭菌的患者。

要進行FMT,臨床醫生和糞便銀行從健康供體中取出糞便,並將糞便加工成均質溶液,以植入病人體內。加工的FMT處理儲存在-80℃以保護供體的獨特的共生細菌群落。研究認為使用FMT可以恢復由於過度使用抗生素或潛在的致病原因而導致丟失保護性的多樣性細菌不平衡。

FMT vs. HMT PROCESSING

Human Microbiota Transplant, or HMT®, is the next generation of Fecal Microbiota Transplantation (FMT), a novel treatment in clinical use that is shown to be over 90% effective for treating C. difficile infection in patients who are unresponsive to traditional antibiotic therapy. 

HMT’s add several steps to the processing methodology of an FMT to remove a much larger portion of the undigested food particulate in the feces and to preserve as much of the bacterial community as possible in an anaerobic environment.
