BACKGROUND: Invasive fungal wound infections (IFIs) are a recognized threat for
personnel who sustain combat-related blast trauma in Afghanistan. Blast trauma,
particularly when dismounted, has wounds contaminated with organic debris and
potential for mold infection. Trauma-associated IFI is characterized by recurrent
wound necrosis on serial debridement with histologic evidence of invasive molds
and/or fungal culture growth. Wounds with mold growth but lacking corresponding
recurrent necrosis present a clinical dilemma of whether to initiate antifungal
treatment. Our objective was to assess the clinical significance of fungal
culture growth without recurrent wound necrosis. METHODS: US military personnel
wounded during combat in Afghanistan (June 2009 to August 2011) were assessed for
growth of mold from wound cultures and/or histopathologic evidence of IFI.
Identified patients were stratified based on clinical wound appearance
(with/without recurrent necrosis), and the resultant groups were compared for
injury characteristics, clinical management, and outcomes. RESULTS: A total of 96
patients were identified: 77 with fungal elements on histopathology and/or fungal
growth plus recurrent wound necrosis and 19 with fungal growth on culture but no
wound necrosis after initial debridements. Injury patterns and severity were
similar between the groups. Patients with recurrent necrosis had more frequent
fevers and leukocytosis during the first 2 weeks after injury, and the majority
received antifungal therapy compared with only three patients (16%) without
recurrently necrotic wounds. Overall, patients without recurrent wound necrosis
had significantly less operative procedures (p = 0.02), shorter stay in the
intensive care unit (p < 0.01), and lower rates of high-level amputations (5% vs.
20%) and deaths (none vs. 8%) despite no or infrequent antifungal use.
CONCLUSION: The finding of molds on wound culture among patients with blast
trauma in the absence of recurrently necrotic wounds on serial debridement does
not require systemic antifungal chemotherapy. LEVEL OF EVIDENCE: Therapeutic
study, level IV. Prognosti/epidemiologic study, level III.
