Sci Trans Med:如何增加癌症患者有益菌群?

2018-09-28 佚名 生物探索

感染是异基因造血干细胞移植过程中最常见和严重的并发症之一,癌症患者通常需要服用大量的抗生素,而抗生素治疗会破坏患者肠道微生物群的多样性,导致许多有益微生物的丧失。近日,纪念斯隆凯特琳癌症中心的研究人员找到一种安全有效的方法——自体粪便微生物群移植(auto-FMT),可以帮助该手术患者补充有益的肠道细菌。

感染是异基因造血干细胞移植过程中最常见和严重的并发症之一,癌症患者通常需要服用大量的抗生素,而抗生素治疗会破坏患者肠道微生物群的多样性,导致许多有益微生物的丧失。近日,纪念斯隆凯特琳癌症中心的研究人员找到一种安全有效的方法——自体粪便微生物群移植(auto-FMT),可以帮助该手术患者补充有益的肠道细菌。

在最新的研究中,研究人员将接受异基因造血干细胞移植手术的患者随机分为两组:一组接受标准治疗,另一组接受(auto-FMT)治疗。结果发现, auto-FMT组能使患者的有益肠道细菌在数天内恢复到接近基线水平,从而恢复其消化免疫和其他基本功能。而标准治疗组,患者有益菌通常需要数周时间才能从抗生素治疗中恢复,且会面临其他传染病(艰难梭状芽胞杆菌,Clostridium difficile)的风险。

美国国立卫生研究院下属的国家过敏和传染病研究所(National Institute of Allergy and Infectious Diseases,NIAID)为部分项目提供了资金。

NIAID主任Anthony S. Fauci博士说:“这项重要的研究表明,使用(auto-FMT)的临床干预可以安全地逆转广谱抗生素治疗的破坏性影响。如果该结果在更大范围的研究中得到证实,就可以在强化抗菌治疗后迅速恢复人体健康的微生物群。”

同种异体造血细胞移植需要捐赠者(通常是家族成员)提供给受体干细胞,这些干细胞可以重建骨髓造血细胞和免疫功能,以便对抗癌症。虽然抗生素对于预防干细胞受者的细菌感染至关重要,但是,抗生素也会破坏有益的细菌;这些细菌可以增强免疫功能和抵抗感染。有益菌的丧失增加了某些危及生命的传染病和移植物抗宿主病(GVHD)的风险。

这项研究的对象是癌症患者,他们提供自己的粪便样本,这些样本在细胞移植前被冷冻和储存。几周后,当医生证实移植的细胞正在生长时,他们评估了病人有益的肠道细菌的状况。前25名缺乏已知有益菌的患者被纳入了研究,并被随机分配到不同的治疗组:14名接受灌肠(auto-FMT)治疗,11名接受标准治疗。

结果显示,接受(auto-FMT)治疗的患者,其细菌多样性、成分和功能均持续恢复;11例对照组有益菌的恢复延迟。

研究人员将继续监测研究患者,以确定auto-FMT是否改善患者预后,如细菌、病毒和真菌感染的发生率和严重程度,以及GVHD的发生率和严重程度。而来自健康捐赠者的FMT在恢复有益细菌方面是否会像病人自己的粪便样本一样有益,还有待进一步研究。
