Phage Therapy Against Antibiotic-Resistant and Multidrug-Resistant Infections Involving Nonhealing Wounds and Prosthetic Joint Infections Associated With Biofilms: A Mini-Review.

Chronic wounds and prosthetic joint infections are difficult to treat and are associated with a high burden of disease and economic cost. The rise of antibiotic resistance and the understanding of biofilm formation has inflamed an already challenging situation. Bacteriophage therapy has been used throughout the last century to treat bacterial infections. However, in the last 10 years, there has been a resurgence in phage therapy as a novel innovative treatment for nonhealing wounds. This mini systemic review assesses relevant clinical studies, case series and trials over 5 years associated with safety, treatment and success rates of phage therapy concerning nonhealing and prosthetic joint infections. A search of PubMed, Web of Science, Cochrane and Clinical Trials.gov databases resulted in 3151 studies, 27 met the criteria, and a total of 152 bacterial infections were treated from 130 individuals. Most common pathogen isolated in wounds was P. aeruginosa, and S. aureus was mostly associated with prosthetic joint infections. Treatment modalities differed across studies, adverse effects were limited, and success rate was deemed to be 91%.
