Overcoming Challenges in Wound Infection: Biofilm and Antimicrobial Resistance

Area of Science:

• Wound healing and infectious disease research.
• Antimicrobial resistance (AMR) and biofilm dynamics.

Background:

• Chronic wounds affect 1-2% of the global population, with increasing prevalence due to aging and comorbidities like diabetes.
• Infections and antimicrobial resistance (AMR) significantly impede wound healing and patient outcomes.
• Microbial biofilms are a major factor in chronic wound persistence, promoting AMR and evading immune responses.

Purpose of the Study:

• To review current challenges in chronic wound treatment, focusing on AMR and biofilms.
• To highlight the limitations of existing diagnostic and therapeutic approaches.
• To discuss recent advances and future directions in biofilm-targeting wound care.

Main Methods:

• Literature review of current diagnostic and therapeutic strategies for chronic wounds.
• Analysis of the impact of antimicrobial stewardship and biofilm prevalence on treatment efficacy.
• Evaluation of emerging treatments for their antibiofilm activity and AMR risk.

Main Results:

• Chronic wound treatment is hindered by AMR and biofilms, which reduce the efficacy of conventional antimicrobials like broad-spectrum antibiotics and silver.
• Biofilms shield pathogens, promote AMR, and complicate treatment, leading to persistent infections.
• While alternative treatments show promise, limited clinical data restricts their widespread adoption.

Conclusions:

• Antimicrobial stewardship and biofilm-targeting strategies are essential for managing chronic wounds.
• Sustainable wound care practices that address biofilms are key to combating AMR and improving patient outcomes.
• Further clinical research is needed to validate novel antibiofilm therapies.
