Rhino-Orbito-Cerebral Mycosis and COVID-19: From Bad to Worse?

BACKGROUND: There has been an increase an alarming rise in invasive mycoses during COVID-19 pandemic, especially during the second wave. AIMS: Compare the incidence of invasive mycoses in the last three years and study the risk factors, manifestations and outcomes of mycoses in the COVID era. METHODOLOGY: Multicentric study was conducted across 21 centres in a state of western India over 12-months. The clinico-radiological, laboratory and microbiological features, treatment and outcomes of patients were studied. We also analysed yearly incidence of rhino-orbito-cerebral mycosis. RESULTS: There was more than five-times rise in the incidence of invasive mycoses compared to previous two-years. Of the 122 patients analysed, mucor, aspergillus and dual infection were seen in 86.9%, 4.1%, and 7.4% respectively. Fifty-nine percent had simultaneous mycosis and COVID-19 while rest had sequential infection. Common presenting features were headache (91%), facial pain (78.7%), diplopia (66.4%) and vison loss (56.6%). Rhino-orbito-sinusitis was present in 96.7%, meningitis in 6.6%, intracranial mass lesions in 15.6% and strokes in 14.8%. A total of 91.8% patients were diabetic, while 90.2% were treated with steroids during COVID-19 treatment. Mortality was 34.4%. CONCLUSION: Invasive fungal infections having high mortality and morbidity have increased burden on already overburdened healthcare system. Past illnesses, COVID-19 itself and its treatment and environmental factors seem responsible for the rise of fungal infection. Awareness and preventive strategies are the need of hours and larger studies are needed for better understanding of this deadly disease.
