Rethinking antimicrobial prophylaxis in patients receiving medicinal leech therapy

Area of Science:

• Microbiology
• Infectious Diseases
• Surgical Innovation

Background:

• Medicinal leech therapy is a valuable tool in reconstructive surgery.
• Antimicrobial prophylaxis is often used to prevent infections during leech therapy.
• Changes in microbial resistance patterns necessitate re-evaluation of prophylactic strategies.

Observation:

• A case of reconstructive surgery complicated by infection following medicinal leech therapy is presented.
• Aeromonas species isolated from leeches showed resistance to commonly used prophylactic agents.
• This resistance pattern poses a significant challenge to infection prevention.

Findings:

• The study highlights evolving antimicrobial resistance in Aeromonas isolates from medicinal leeches.
• Inadequate prophylaxis due to resistant isolates can lead to severe complications, including graft infection.
• Clinicians must be aware of local resistance patterns when selecting prophylaxis.

Implications:

• This case underscores the need for updated guidelines on antimicrobial prophylaxis for medicinal leech therapy.
• Monitoring antimicrobial resistance in leech-associated flora is essential for patient safety.
• Choosing appropriate prophylactic agents is critical to mitigate risks in patients undergoing leech therapy.
