ABSTRACT
Acute invasive fungal rhinosinusitis (AIFR) is a life-threatening infection often found in immunocompromised patients. In the COVID-19 era, reports of AIFR have emerged, with high mortality and morbidity rate. This paper presents two cases of COVID-19 associated AIFR with the combined proven fungal etiology of Aspergillus flavus and Rhizopus arrhizus in case 1 and Aspergillus fumigatus and Rhizopus arrhizus in case 2. Both patients received liposomal amphotericin B then posaconazole combined with aggressive surgical debridement of necrotic tissues with a favorable clinical outcome. Mixed etiology AIFR can influence the outcome; hence, further studies are required upon this new threat.
ABSTRACT
INTRODUCTION: Acute invasive fungal rhino-sinusitis (AIFR) is a life-threatening infection that is mostly found in immunocompromised patients with serious morbidity and mortality. Recently, reports of AIFR have also emerged among SARS-CoV-2 infected patients. CASE PRESENTATION: A 50-year-old diabetic woman, previously diagnosed with COVID-19 pneumonia, was presented to the hospital with left facial pain on day 12 after discharge. Paranasal sinuses computed tomography was performed and according to the mucosal thickening in both maxillary sinuses and ethmoidal air cells, the patient underwent functional endoscopic sinus surgery (FESS) and necrosis were observed. The histopathologic examination revealed mycelium with septation suspected to Aspergillus and the culture was consistent with Aspergillus flavus and also Aspergillus niger . We reported a case of COVID-19 associated AIFR with two combined Aspergillus species from Iran. The patient received liposomal amphotericin B, which then switched to voriconazole combined with aggressive surgical debridement of necrotic tissues with a clinically favorable outcome. CONCLUSION: Mixed etiology AIFR can influence the outcome. However, further investigation is required upon this new threat.
ABSTRACT
COVID-19 first emerged in Wuhan, China, in December 2019. Since that time, the frequency of bacterial and fungal coinfections has been continuously increasing. Although invasive pulmonary aspergillosis is being increasingly recognized in association with COVID-19, there is limited information regarding COVID-19-associated mucormycosis. We describe a 50-year-old woman with uncontrolled diabetes who received systemic corticosteroids and remdesevir during her admission for COVID-19. A few days after discharge, the patient was readmitted because of facial swelling and numbness, and a diagnosis of COVID-19-associated rhinosinusitis mucormycosis caused by Rhizopus arrhizus (formerly called Rhizopus oryzae) was confirmed with sequencing of the internal transcribed spacer region of the ribosomal DNA. This report aimed to address the importance of short-term follow-up for COVID-19 patients who have received systemic corticosteroids, particularly those with predisposing conditions, because early detection and prompt, aggressive treatment are essential for the management of invasive fungal infections.

Case reports of CAPA emerged. In most of the reports, the predominant species is Aspergillus fumigatus. Uncommon species are less reported. Due to poor clinical outcome with Aspergillus terreus, the increasing reports with this agent require attention.
