Description
Summary:Rhinocerebral mucormycosis is a rare, life-threatening fungal infection that affects the sinuses, nasal passages, and brain. Its management remains challenging owing to high mortality rates. Combination antifungal therapy is an area of ongoing research aimed at improving outcomes. We aimed to describe the clinical management and outcomes of patients with rhinocerebral mucormycosis who were treated with antifungal combination therapy. This retrospective case series included 10 patients diagnosed with rhinocerebral mucormycosis at two academic medical centers between January 2008 and July 2023 who received initial antifungal therapy with liposomal amphotericin B (L-AmB), alone or in combination, within 24 h of diagnosis. Clinical data were extracted from the medical records. Most patients were males (70 %) with uncontrolled diabetes (71.4 %). L-AmB was used as the initial therapy in all patients, either as monotherapy (n = 4) or combination therapy (n = 6), followed by posaconazole maintenance. The combinations included L-AmB with posaconazole (n = 4), L-AmB with micafungin (n = 3), or both (n = 3). The overall mortality rate was 50 %. Survivors had high morbidity, with median 31-day hospitalizations and 50 % readmission rate. Despite aggressive management, rhinocerebral mucormycosis has high mortality and morbidity rates. While combination antifungal therapy aims to improve cure rates, our case series showed higher mortality rates than monotherapy. Additional research is warranted to optimize management approaches for this devastating infection.
