Successful treatment of rhino-orbital mucormycosis by a new combination therapy with liposomal amphotericin B and micafungin

Abstract

Mucormycosis is a rapidly progressive fungal infection that usually occurs in patients with diabetes mellitus or in immunocompromised patients. Sinus involvement is the most common clinical presentation and the rates of mortality increase with the orbital extension. The treatment of mucormycosis includes aggressive surgical debridement and systemic antifungal therapy. Early diagnosis and prompt initiation of effective antifungal drugs are essential for successful outcome. However, the role of orbital exenteration for the case of orbital involvement remains controversial, and the drugs effective against mucormycosis are limited. We present a successfully treated case with rhino-orbital mucormycosis caused by Rhizopus oryzae in a diabetic and dialysis patient. The early diagnosis, surgical debridement and a new combination therapy with liposomal amphotericin B and micafungin were effective. This new combination antifungal therapy will be useful for the treatment of mucormycosis.
