ABSTRACT
Mucormycosis ranks third among invasive mycoses after Candidiasis and Aspergillosis and is associated with high mortality. Its incidence has increased with the rising number of immunosuppressed patients. In developing countries, the most common predisposing factor is uncontrolled diabetes mellitus (DM), whereas in developed countries it is immunosuppressive conditions. To examine local epidemiological data, predisposing factors, diagnostic and therapeutic options and survival in our center eighty-six adult mucormycosis patients between 2000 and 2020 were retrospectively analyzed. Thirty-nine (45.35%) were male, 47 (54.65%) were female, and the median age was 52 years (IQR, 42.5-62). The most frequent clinical presentation was sinus involvement, observed in 77 cases (89.53%). Of these, 38 (44.18%) were sinonasal, 5 (5.81%) sinoorbital, 9 (10.47%) rhinocerebral, and 25 (29.07%) rhino-orbito-cerebral mucormycosis. The remaining 9 cases (10.47%) had pulmonary mucormycosis. Predisposing factors included hematologic diseases in 51 patients (59.30%), DM in 33 (38.37%), solid organ transplantation (SOT) in 7 (8.14%), and solid organ malignancy in 7 (8.14%). The most common symptoms were fever (70.93%), swelling around the eyes and face (51.16%), pain (40.7%), erythema (34.88%), nasal discharge (30.23%), and headache (25.58%). Most frequent physical examination findings were necrotic lesions in the oral cavity and sinuses (87.21%), ophthalmoplegia (29.07%), ptosis (26.74%), vision loss (25.58%), and proptosis (22.09%). In all cases, amphotericin B formulations were preferred as initial therapy. Patients who received combination therapy (n = 14), 13 used posaconazole (POS) + liposomal amphotericin B (L-AmB) and one patient used itraconazole (ITC) + L-AmB. POS was administered to 14 patients receiving sequential oral therapy. The median duration of amphotericin B therapy was 46.5 days (IQR, 14.7-84.5), and the median total duration of antifungal therapy was 46.5 days (IQR, 14.7-90.3). The most common adverse effect of amphotericin B formulations was hypokalemia [L-AmB 68.75%, amphotericin B deoxycholate (AmB-D) 54.84%, amphotericin B lipid complex (ABLC) 50%]. At least one surgical intervention was performed in 74.42% of cases. The 12-week mortality rate was 48.84%, overall mortality rate was 61.63%. In analysis advanced age [12-week: OR: 1.04 (95% CI: 1.01-1.07), p = 0.011; overall: OR: 1.04 (95% CI: 1.01-1.07), p = 0.026 respectively], coexistence of both hematologic disease and DM [12-week OR: 5.73 (95% CI: 1.16-28.33), p = 0.032] associated with mortality. No significant difference was observed in 12-week mortality between surgical and non-surgical patients (p = 0.107). In contrast, overall mortality was significantly higher in the non-surgical group (81.8% vs. 54.7%, p = 0.024). In univariable logistic regression analysis, surgical intervention was associated with a 73.2% reduction in the odds of overall mortality (OR: 0.268, 95% CI: 0.082-0.882, p = 0.030). In the multivariable logistic regression analysis, age was the only variable significantly associated with 12-week and overall mortality (respectively, p = 0.004 and p = 0.026). Each one-year increase in age was associated with an OR of 1.05 (95% CI: 1.02-1.09) for 12-week mortality and 1.04 (95% CI: 1.01-1.07) for overall mortality. In conclusion; our study showed that despite advanced diagnostic methods and antifungals, mortality remained high, sinus involvement was the most frequent involvement, surgical debridement increased survival, but increasing age was associated with poor prognosis.
