Abstract
Mucormycosis is a rare fungal infection with an extremely high morbidity and mortality. Data on the burden of the disease in the Arab world is lacking. The aim of this study is to highlight the incidence and outcome of this infection in a tertiary care center in the Kingdom of Saudi Arabia (KSA).
In this retrospective study we included all mucormycosis cases admitted to our center between January 2013 and December 2019. A total of 18 proven patients with a median age of 43.5 years (range 13-72 years, 72% males) were identified. The most common presentation was cutaneous and rhino-orbitocerebral, followed by gastrointestinal mucormycosis. Apophysomyces variabilisRhizopus oryzae) were the main fungal isolates on molecular testing.
Trauma was the chief underlying etiology (41.0%) with motor vehicle accident (MVCs) being the predominant type (43.0%). For this reason, most of our patients were young with cutaneous disease and had a better prognosis.
All patients received liposomal amphotericin B alone or in combination with other antifungal agents. Repeated aggressive debridement and reversal of the underlying factor was attempted in all patients. This underscores the lower mortality (27.8%) seen in this group.
The diagnosis of Mucorales infection is challenging. A high index of suspicion with prompt treatment is required to improve the high mortality of this aggressive disease. Further studies are needed to understand the epidemiology and outcome of this disease in Saudi Arabia. (C) 2020 The Author(s).
