BACKGROUND: Coccidioidomycosis is a fungal infection of the desert southwestern United States. It may be self-limited or may require antifungal therapy. Currently used triazoles (eg, fluconazole and itraconazole) have largely supplanted amphotericin B, which is fraught with adverse effects. Limited case reports and small open-label trials show that voriconazole and posaconazole benefit patients with coccidioidomycosis refractory to first-line agents.
METHODS: We conducted a retrospective review of patients prescribed voriconazole or posaconazole for coccidioidomycosis at our institution between 1 January 2006 and 1 August 2010. Outcomes were assessed with both a retrospectively applied Mycosis Study Group score (ie, a composite score for symptoms, serology, and radiographic findings) and the documented impressions of treating medical practitioners.
RESULTS: Twenty-one patients who received voriconazole and 16 who received posaconazole met study criteria. After a median duration of 6 months of voriconazole treatment, 14 of 21 patients (67%) were improved in overall status, 5 were unchanged, and 2 were unresponsive to voriconazole. After a median of 17 months of posaconazole treatment, 12 of 16 patients (75%) showed improvement, 1 was unchanged, and 3 were unresponsive due to medication intolerance or relapsed infection.
CONCLUSIONS: Voriconazole and posaconazole are reasonable but not infallible options for salvage treatment of refractory coccidioidomycosis. Prospective comparative trials are required to provide further insights into their efficacy and utility.
