Abstract
Coronavirus disease 2019 (COVID-19) is an acute viral illness caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Opportunistic infections such as mucormycosis have been reported among COVID-19 patients particularly in South Asian countries during the second wave of this pandemic. It is necessary to re-evaluate any changes in traditional risk factors associated with mucormycosis such as diabetes mellitus, organ transplant, etc in the precedent of ongoing COVID-19 pandemic. We conducted a systematic review using electronic databases. A total of 115 COVID-19 patients who were diagnosed with mucormycosis were included in this study. Diabetes mellitus was the most common co-morbidity with 77.1%, followed by hypertension (29.5%) and renal disease (14.3%). 55.2% of the patients had received dexamethasone for COVID-19 infection. Ten patients (11.5%) had received tocilizumab. Sinuses were the most common site of mucormycosis among COVID-19 patients at 79.4% with maxillary sinus (47.4%) being most commonly infected. Orbits were the second most prevalent site at 56.7% and lungs were infected with mucor at 11.3%. The mean duration between the diagnosis of COVID-19 infection and mucormycosis was 16.15 days (range 2-90 days). Cavernous sinus was either infiltrated or encased in 14 patients (14.4%). Cerebral involvement was seen in terms of abscess, infarcts, or edema in 12 patients (12.4%). Only 76 patients had data on the outcomes, out of which 37 (48.7%) patients had died. Diabetes mellitus is still the most common co-morbidity similar to non-COVID-19 patients. More than 90% of the patients with COVID-19 infection had received steroids. Complications such as cavernous sinus thrombosis, cerebral infarcts, abscesses were common. Indiscriminate use of steroids in patients needs to be avoided and focus needs to be put on tight blood sugar control in diabetic patients. Studies are needed to confirm the role of the SARS-CoV-2 virus in causing immune dysfunction and mucormycosis.
