ABSTRACT
Background Acute invasive fungal rhinosinusitis (AIFRS) is a rare aggressive life-threatening infection that affects immunocompromised individuals. Recently, an increase in the incidence of this infection has been reported in patients who have SARS-CoV-2 infection or recently recovered. This study was to assess the outcome and define risk factors that might affect the outcome in SARS-CoV-2-related AIFRS. A prospective observational study included 54 patients diagnosed with SARS-CoV-2-related AIFRS. Controlling the predisposing factors, systemic antifungal, and early surgical debridement was performed. The mortality rate was calculated. Age, sex, underlying risk factors, the extent of the disease, debridement technique, and other biochemical variables were evaluated regarding their impact on survival. Patients were followed up for 3 months. Results Fifty-four patients with a mean age of 48.1 years. Diabetes mellitus was the most common comorbidity affecting 52 patients (96.3%). Intracranial and intraorbital extension had a predictive value for mortality (P value 0.050 and 0.049 respectively). However, only intracranial extension was the independent predictor of mortality. Biochemical variables were higher than the normal range, but only serum ferritin level above 165 ng/ml was an independent predictor of mortality in patients with AIFR. The mortality rate was 38.9%. Conclusion The extent of the disease has a major impact on survival, so early diagnosis of AIFRS within patients infected with SARS-CoV-2 or recently recovered is essential to reduce mortality.
