Current and future management of Clostridioides difficile infection (CDI) including antibiotic treatment is increasingly focused on preventive strategies, either prevention of recurrent CDI (rCDI) or primary prevention of CDI. In addition to newer narrow spectrum antibiotics and pulse dosing of antibiotic treatment, multiple widely differing approaches to prevention of CDI and rCDI are under clinical development or recently approved for clinical use. They include immunologics, both passive monoclonal antibodies and active vaccines targeted at C. difficile toxins, approaches to reduce antibiotic dysbiosis in the gut, microbiome restoration using fecal microbiome transplants (FMT) or biotherapeutic bacterial derivatives, and substitution of non-toxigenic C. difficile (NTCD) for toxigenic C. difficile. Newer antibiotics, monoclonal antibodies, and FMT are targeted at reducing rCDI whereas vaccines and reduction of antibiotic dysbiosis in the gut are targeted at prevention of primary CDI. Biotherapeutics may be used for prevention of either primary CDI or rCDI. Approaches such as monoclonal antibodies, FMT, and biotherapeutics provide rapid but transient preventive benefits, whereas vaccines require weeks to months to be effective, but will presumably provide long term prevention. More rapid but transient prevention strategies such as FMT and biotherapeutics could be used in combination with vaccines to provide both rapid and durable CDI prevention.
目前和未来的艰难梭菌感染(CDI)管理,包括抗生素治疗,越来越侧重于预防策略,无论是预防复发性 CDI(rCDI)还是预防 CDI 原发性感染。除了新型窄谱抗生素和抗生素治疗脉冲剂量外,还有多种广泛不同的方法正在临床开发或最近批准用于临床,用于预防 CDI 和 rCDI,包括免疫疗法,针对艰难梭菌毒素的被动单克隆抗体和主动疫苗,减少肠道抗生素失调的方法,使用粪便微生物组移植(FMT)或生物治疗细菌衍生物来恢复微生物组,以及用非产毒艰难梭菌(NTCD)代替产毒艰难梭菌。新型抗生素、单克隆抗体和 FMT 旨在减少 rCDI,而疫苗和减少肠道抗生素失调则旨在预防原发性 CDI。生物治疗药物可用于预防原发性 CDI 或 rCDI。单克隆抗体、FMT 和生物治疗药物等方法提供快速但短暂的预防益处,而疫苗则需要数周至数月才能有效,但预计将提供长期预防。更快速但短暂的预防策略,如 FMT 和生物治疗药物,可与疫苗联合使用,以提供快速和持久的 CDI 预防。
