Rhino-orbital-cerebral mucormycosis: fungal epidemic in a viral pandemic.

ABSTRACT

BACKGROUND: Treatment of coronavirus disease 2019 infection can result in immunosuppression. Rhino-orbital-cerebral mucormycosis is a frequent co-infection, even after recovery. METHODS: An ambispective interventional study was conducted of 41 coronavirus patients with rhino-orbital-cerebral mucormycosis at a tertiary care centre from March to May 2021. RESULTS: There were 28 males and 13 females with a mean age of 48.2 years (range, 21-68 years). Twelve had long-standing diabetes mellitus and 28 had been recently diagnosed. Thirty-six had received systemic corticosteroids for coronavirus disease 2019. Nasal signs were present in 95 per cent of patients, ophthalmic symptoms and signs in 87 per cent, palatal necrosis in 46.3 per cent, facial signs in 24.3 per cent, nerve palsies in 60.9 per cent, and intracranial involvement in 21.9 per cent. Treatment with amphotericin B was based on clinical features and co-morbidities. Endonasal debridement was performed in 51.2 per cent of patients, total maxillectomy in 14.6 per cent and orbital exenteration in 9.7 per cent. At the last follow up, 37 patients (90.24 per cent) were on antifungal therapy; 4 (9.75 per cent) did not survive. CONCLUSION: Early detection may improve survival. Follow up of high-risk patients after coronavirus disease 2019 infection is paramount.
