Amphotericin B in the management of COVID-19 associated mucormycosis

Background: Amphotericin B is considered the drug of choice for primary treatment of mucormycosis. During second wave of COVID-19 pandemic there was severe scarcity of liposomal amphotericin B. This study aims to determine role of various formulations of amphotericin and their side effects when used for the treatment of COVID-19 associated mucormycosis. Methods: A retrospective study was conducted between May 2021 and December 2021 at a tertiary care centre. 380 patients with post-COVID rhino-orbito-cerebral mucromycosis (ROCM) were included in the study. Liposomal amphotericin B, conventional amphotericin deoxycholate, lipid complex amphotericin B was used in the treatment. Patients were observed for side effects like fever, chills, rigors, hypokalemia, renal function derangements, thrombophlebitis and respiratory difficulties. Results: Majority of patients received liposomal amphotericin B (331) and 31 patients received conventional amphotericin deoxycholate and 5 patients were given lipid complex amphotericin B injections. The most commonly encountered side effects were of the mild type constituting chills (98% with liposomal and 100% with amphotericin deoxycholate), and fever (94% with liposomal and 74% with amphotericin deoxycholate). Conclusions: Our study highlights the role of various formulations of amphotericin B in the treatment of COVID-19 mucormycosis.
