Combating Superbug Without Antibiotic on a Postamputation Wound in a Patient with Diabetic Foot

Area of Science:

• Wound Healing
• Infectious Diseases
• Regenerative Medicine

Background:

• Diabetic foot complications pose significant limb- and life-threatening risks.
• Conventional therapies are often insufficient for severe infections, particularly with peripheral arterial insufficiency.
• Multidrug-resistant organisms present a growing challenge in managing diabetic foot infections.

Observation:

• A diabetic patient presented with a postamputation wound infected by multidrug-resistant Acinetobacter baumannii/haemolyticus.
• The infection was resistant to nearly all available antibiotics, leading to a poor clinical response to antimicrobial therapy.
• Standard antibiotic treatment was discontinued due to lack of efficacy.

Findings:

• A novel treatment approach combining autologous platelet-rich gel, negative pressure wound therapy, and microcirculation improvement was implemented.
• This multimodal strategy successfully eradicated the superbug infection.
• Complete wound closure was achieved, demonstrating the efficacy of the combined therapeutic interventions.

Implications:

• This case highlights a promising alternative treatment strategy for complex diabetic foot infections caused by multidrug-resistant bacteria.
• The findings suggest that regenerative medicine approaches, such as platelet-rich gel, can be effective when conventional antibiotics fail.
• Improved microcirculation and advanced wound care are crucial for successful outcomes in challenging diabetic foot cases.
