Early Surgical Intervention Followed by Antifungals in Rhino-Orbital Mucormycosis in Patients With COVID-19 Favors Clinical Outcome: A Case Series.

Mucormycosis is an invasive fungal infection occurring in patients with or without preexisting medical illnesses. During the ongoing coronavirus disease 2019 (COVID-19) pandemic, there have been increasing reports of bacterial and fungal coinfections among some COVID-19 patients with preexisting comorbid illnesses such as diabetes and hypertension, with mucormycosis being one of them. The management of this dreaded fungal infection demands early and prompt surgical intervention to thoroughly remove the infected tissue and necrotic material to reduce the tissue burden of this invasive organism. This should be accompanied by expeditious initiation of amphotericin B along with supportive therapy. Here we present five cases of rhino-orbital mucormycosis in patients with COVID-19, all of whom presented with orbital and facial swelling (three had symptoms of impending blindness) under the backdrop of COVID-19 symptoms in the form of intermittent fever and slight dyspnea. Our treatment strategy comprised an expeditious use of early surgical intervention and amphotericin B along with the control of cytokine storm and hyperglycemia. This treatment strategy eventually resulted in an improved clinical outcome.
