Combat-Related Invasive Fungal Wound Infections

Area of Science:

• Medical Mycology
• Infectious Diseases
• Military Medicine

Background:

• Combat-related invasive fungal wound infections (IFIs) are a significant cause of morbidity in military personnel following explosive blast injuries.
• These infections resemble trauma-associated IFIs in civilians, often occurring in penetrating wounds contaminated with environmental debris.
• Specific risk factors include dismounted blast injuries in Afghanistan, leading to amputations and requiring massive blood transfusions.

Purpose of the Study:

• To highlight the emergence and characteristics of combat-related IFIs.
• To outline diagnostic approaches for these challenging infections.
• To provide therapeutic recommendations for managing IFIs in military casualties.

Main Methods:

• Diagnosis relies on identifying recurrently necrotic wounds after debridement.
• Histopathology with special stains and fungal cultures of affected tissue are key diagnostic tools.
• Treatment involves aggressive surgical debridement and consideration of empiric antifungal therapy.

Main Results:

• Early identification of necrotic wounds and histopathological evidence are critical for diagnosing IFIs.
• Fungal cultures provide supportive diagnostic information.
• Treatment strategies emphasize surgical intervention and prompt antifungal administration.

Conclusions:

• Aggressive surgical debridement is the cornerstone of IFI management.
• Empiric antifungal therapy, including liposomal amphotericin B and voriconazole, is recommended upon suspicion.
• Treatment regimens should be tailored based on identified fungal species, such as Mucorales, Aspergillus, or Fusarium.
