The Rationale for Using Bacteriophage to Treat and Prevent Periprosthetic Joint Infections

Area of Science:

• Biomedical Engineering
• Infectious Diseases
• Microbiology

Background:

• Prosthetic joint infection (PJI) is a severe complication of joint replacement surgery.
• Current treatments often fail due to bacterial biofilms on implants, necessitating implant removal and prolonged antibiotic courses.
• PJI poses significant financial, health, and mortality burdens.

Purpose of the Study:

• To explore bacteriophages (phages) as a novel therapeutic or prophylactic strategy for PJI.
• To investigate the potential of phages in degrading biofilms and enhancing antibiotic efficacy.
• To examine the emerging role of phages in modulating the innate immune response for PJI clearance.

Main Methods:

• Review of current clinical data and emerging research on bacteriophage therapy for PJI.
• Analysis of phage mechanisms, including biofilm degradation and immune interaction.
• Exploration of potential combinatorial therapies involving phages and antibiotics.

Main Results:

• Bacterial biofilms on prosthetic joints impede conventional antibiotic treatment.
• Bacteriophages demonstrate potential as an alternative or adjunctive therapy for PJI.
• Phages may enhance antibiotic susceptibility and interact with the host immune system.

Conclusions:

• Phage therapy presents a promising, understudied approach for managing PJI.
• This strategy could offer an alternative to revision surgery and prolonged antibiotic treatments.
• Phage therapy has the potential to improve outcomes for numerous PJI patients.
