is a Gram-negative opportunistic pathogen that causes high morbidity and mortality in cystic fibrosis (CF) and immunocompromised patients, including patients with ventilator-associated pneumonia (VAP), severely burned patients, and patients with surgical wounds. Due to the intrinsic and extrinsic antibiotic resistance mechanisms, the ability to produce several cell-associated and extracellular virulence factors, and the capacity to adapt to several environmental conditions, eradicating within infected patients is difficult. is one of the six multi-drug-resistant pathogens (ESKAPE) considered by the World Health Organization (WHO) as an entire group for which the development of novel antibiotics is urgently needed. In the United States (US) and within the last several years, caused 27% of deaths and approximately USD 767 million annually in health-care costs. Several therapies, including new antimicrobial agents, derivatives of existing antibiotics, novel antimicrobial agents such as bacteriophages and their chelators, potential vaccines targeting specific virulence factors, and immunotherapies have been developed. Within the last 2-3 decades, the efficacy of these different treatments was tested in clinical and preclinical trials. Despite these trials, no treatment is currently approved or available. In this review, we examined several of these clinicals, specifically those designed to combat infections in CF patients, patients with VAP, and -infected burn patients.
是一种革兰氏阴性机会致病菌,在囊性纤维化(CF)患者和免疫功能低下的患者中可导致高发病率和死亡率,这些患者包括呼吸机相关性肺炎(VAP)患者、严重烧伤患者以及有手术伤口的患者。由于其内在和外在的抗生素耐药机制、产生多种细胞相关和细胞外毒力因子的能力以及适应多种环境条件的能力,在感染患者体内根除它很困难。是世界卫生组织(WHO)认定的六种急需开发新型抗生素的多重耐药病原体(ESKAPE)之一。在美国,在过去几年中,每年导致27%的死亡,并造成约7.67亿美元的医疗费用。已经开发了几种治疗方法,包括新型抗菌剂、现有抗生素的衍生物、新型抗菌剂如噬菌体及其螯合剂、针对特定毒力因子的潜在疫苗以及免疫疗法。在过去的20 - 30年里,这些不同治疗方法的疗效在临床和临床前试验中得到了测试。尽管进行了这些试验,但目前尚无获批或可用的治疗方法。在本综述中,我们研究了其中一些临床试验,特别是那些旨在对抗CF患者、VAP患者和感染烧伤患者感染的试验。
