Phage to ESKAPE: Personalizing Therapy for MDR Infections-A Comprehensive Clinical Review

Area of Science:

• Microbiology
• Infectious Diseases
• Virology

Background:

• Multidrug-resistant (MDR) ESKAPE pathogens pose a critical global health threat.
• Conventional antibiotics are becoming less effective against these resistant bacteria.
• Bacteriophage therapy is re-emerging as a potential treatment strategy.

Purpose of the Study:

• To review the potential of bacteriophage therapy against MDR ESKAPE pathogens.
• To synthesize preclinical and clinical evidence for phage therapy efficacy.
• To identify challenges and future directions for phage therapy implementation.

Main Methods:

• Comprehensive literature review of preclinical and clinical studies.
• Analysis of compassionate-use cases for phage therapy.
• Evaluation of phage specificity, self-replication, and biofilm activity.

Main Results:

• Phage therapy demonstrates success, particularly in salvage cases for untreatable infections.
• Advantages include specificity, self-replication, and anti-biofilm activity.
• Challenges include narrow host range, bacterial resistance, pharmacokinetics, and regulatory hurdles.

Conclusions:

• Phage therapy is a promising adjunctive tool against MDR infections, not a replacement for antibiotics.
• Phage-antibiotic synergy and phage cocktails can overcome limitations.
• Standardized manufacturing, clinical trials, and adaptive regulations are crucial for future progress.
