Given the rise of multidrug-resistant (MDR) Pseudomonas aeruginosa infections, alternative treatments are needed. Anti-pseudomonal phage therapy shows promise, but its clinical application is limited due to the development of resistance and a lack of biofilm penetration. Recently, adjuvants like CaEDTA have shown the ability to enhance the effectiveness of combined antimicrobial agents. Here, we tested a phage-adjuvant combination and demonstrated the effectiveness of intranasally inhaled phage (KKP10) + CaEDTA in addition to ceftazidime/avibactam (CZA) for chronic P. aeruginosa lung infections. The results emphasize that intranasal inhalation of phage along with CaEDTA can successfully re-sensitize MDR P. aeruginosa to CZA in a triple combination treatment. This promising approach shows potential as a therapy for chronic respiratory tract infections.
鉴于多重耐药（MDR）铜绿假单胞菌感染的增加，需要替代治疗方法。抗铜绿假单胞菌噬菌体疗法显示出前景，但其临床应用因耐药性的产生和缺乏生物膜穿透性而受到限制。最近，像CaEDTA这样的佐剂已显示出增强联合抗菌剂有效性的能力。在此，我们测试了噬菌体 - 佐剂组合，并证明了除头孢他啶/阿维巴坦（CZA）外，经鼻吸入噬菌体（KKP10）+ CaEDTA对慢性铜绿假单胞菌肺部感染的有效性。结果强调，在三联联合治疗中，经鼻吸入噬菌体与CaEDTA可成功使多重耐药铜绿假单胞菌对CZA重新敏感。这种有前景的方法显示出作为慢性呼吸道感染治疗方法的潜力。
