Acute Invasive Fungal Rhinosinusitis and Coronavirus Disease 2019.

Abdel-Aziz, Mosaad; Azab, Noha

ABSTRACT Acute invasive fungal rhinosinusitis (mucormycosis) is a rare, highly fatal disease. This opportunistic fungal infection causes angioinvasion and ischemic tissue necrosis. It mainly affects immunocompromised patients. Since the coronavirus disease 2019 (COVID-19) outbreak, many case reports have described the rhino-orbital-cerebral mucormycosis associated with COVID-19. However, the underlying predisposing factors are unknown. Several factors, other than diabetes, which is the most well-known contributing factor, may be involved in causing this severe fungal infection in COVID-19 patients. These factors may include steroid therapy, which is being used in severely dyspneic patients, the use of broad-spectrum antibiotics that may cause fungal flare-ups, and hospitalization with possible nosocomial infections. In addition, increased serum ferritin levels, possible endothelial damage, and pancreatic islets affection among COVID-19 patients may be implicated. Head and neck surgeons should be aware of the increasing prevalence of craniofacial mucormycosis among COVID-19 patients, as early diagnosis and prompt treatment are essential to improve the outcomes.
