Analysis of epidemiological and clinical aspects in cases of fungal osteomyelitis caused by non-Candida species

Osteomyelitis caused by non- Candida species is rare and often neglected, and current recommendations are based on primarily clinical experience and expert opinion. The objective of this study was to describe a case series of non- Candida fungal osteomyelitis. This retrospective study included 10 patients with non- Candida fungal osteomyelitis. Patients with osteomyelitis and microbiologically confirmed non- Candida species from bone fragment cultures were selected from the institution Infection Control Board database. Fusarium spp. were the most commonly isolated fungus from bone fragment cultures in five patients (50%). The majority did not present immunosuppression. The most common etiology was post-traumatic ( n = 7, 70%), particularly open fractures. All patients were treated with antifungals associated with surgery. The antifungals used were itraconazole in five patients (50%), and voriconazole in another five patients (50%), with a median duration of antifungal therapy of four weeks (range: 3–25). There were no observed deaths within 30 days and one year. An antifungal approach combined with surgical treatment demonstrated favorable clinical outcomes, including low mortality rates and effective remission.
