Abstract

Fusarium species, which are commonly found in soil, water, and organic substrates, can cause serious infections especially in immunocompromised patients. Fusarium infection is notoriously difficult to treat, because of their inherently high minimum inhibitory concentrations (MICs) to most antifungal agents. There have been limited data on invasive fusariosis in Korea. We identified 57 patients with culture-proven fusariosis at Samsung Medical Center, Seoul, Korea, from September 2003 through January 2017. Invasive fusariosis was defined as any case with at least one positive blood culture or with concurrent involvement of 2 or more non-contiguous sites. Superficial infections such as keratitis and onychomycosis were excluded. We reported 14 cases of invasive fusariosis categorized according to the European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria, of which 6 cases were Fusarium fungemia. Hematologic malignancies (7/14, 50%), solid organ transplantation (2/14, 14.2%), or immunosuppressive therapy (2/14, 14.2%), were the predominant underlying conditions. The overall mortality rate was 37%, however, that of disseminated fusariosis was up to 83%. Antifungal treatment with voriconazole or liposomal amphotericin B was commonly administered. In this report, we described the clinical characteristics and treatment outcomes of invasive fusariosis in Korea. Given the high mortality in disseminated cases, invasive fusariosis is becoming a therapeutic challenge to clinicians treating immunocompromised patients.
