Mycological profile of acute invasive fungal rhinosinusitis during COVID-19 pandemic at a tertiary care hospital

Abstract

Introduction: During the coronavirus disease-19 (COVID-19) pandemic, a surge in acute invasive fungal rhinosinusitis (AIFRS) cases with high mortality was reported in India. Objective: The objective was to study the spectrum of fungus associated with AIFRS during the pandemic of COVID-19. Materials and Methods: A total of 51 patients who were clinically diagnosed as cases of acute invasive rhinosinusitis in the department of ear, nose and throat (ENT) were included in the study. The clinical data along with demographic details were noted, and fungal identification was done using a conventional method. Results: Out of 51 patients, 66.6% were males and 33.4% females. Predominantly affected age group was 41–50 years. Out of 51 patients, 92.15% (47/51) had suffered from COVID-19 and 7.8% (4/51) did not have COVID-19 infection previously. Thirty-seven patients out of 51 (72.54%) were diabetics. Out of 51 samples collected from patients, 94.11% (48/51) were fungal culture-positive and only 5.8% (3/51) were culture-negative. A total of 52 fungi were isolated from the 48 culture-positive samples. Mucormycetes were predominantly isolated from the samples followed by Aspergillus species and Candida species. Among mucormycetes, Rhizopus species was the predominantly isolated. Conclusion: Patients with COVID-19, especially those at high risk, need to undergo an ENT examination once they recover because an early identification of AIFRS and a strong clinical suspicion of the disease are crucial for a successful course of treatment and to improve patient prognosis.
