Epidemiology, Clinical Manifestations, Treatment, and Outcome of Mucormycosis: A Review of 77 Cases From a Single Center in France.

Background

The aim of this study was to assess the epidemiology, clinical manifestations, and outcome of mucormycosis over 15 years in a single center in France.

Methods

We conducted a retrospective analysis of all mucormycosis cases in our institution from 1 January 2006 to 31 December 2020 and analyzed patients' medical records, laboratory results, and treatment to describe the epidemiology, clinical manifestations, diagnosis, treatment, and outcome. Mucorales quantitative polymerase chain reaction (qPCR) for the diagnosis was implemented in 2015.

Results

Seventy-seven mucormycosis cases were analyzed in 77 patients, with a median age of 54 years (60% male). Identified risk factors were hematological diseases (46 cases [60%]), solid malignancies (2 cases), solid organ transplants (3), burns (18), diabetes only (7), and trauma (1). Sites of infection were lungs (42%), sinus (36%), skin (31%), central nervous system (9%), liver (8%), others (6%), and disseminated (12%). Diagnosis remained difficult and qPCR contributed to mucormycosis diagnosis in 30% of cases. Among hematology patients, serum qPCR was the only positive test in 15% of cases. A mixed mold infection was diagnosed in 24 of 77 (31%) patients. Surgical treatment was undertaken in 43 (56%) cases. Most patients received liposomal amphotericin B (89%), with a combination therapy in 18 of 77 cases (23%). Three-month survival rate was 40% (95% confidence interval [CI], .30-.53]). As for treatment, adjunction of surgery (hazard ratio, 0.47 [95%CI, .25-.91);

Conclusions

Mucormycosis remained associated with high mortality, especially in the hematological and burn populations. Surgery in combination with antifungal treatment was associated with improved survival.
