Mixed invasive molds among COVID-19 patients

Purpose Due to surge in COVID cases during the second wave of the COVID pandemic, the healthcare system collapsed in India with shortage of hospital beds, injudicious use of steroids and other immunomodulators, and poor glycaemic monitoring among a population with pre-existing risk of diabetes. Fungal epidemic was announced amid COVID pandemic with several cases of COVID-associated mucormycosis and aspergillosis being reported. But, there is no data regarding mixed fungal infections in COVID patients. Materials and Methods The study presented a series of ten consecutive cases with dual invasive molds in patients infected with SARS-CoV-2. Among patients hospitalized with the diagnosis of COVID in May 2021 at a tertiary care center in North India, ten microbiologically confirmed dual/mixed COVID-associated mucor-aspergillosis (CAMA) were evaluated. Results All patients were diabetics with the majority having severe COVID pneumonia (6/10, 60%) either on admission or in the past one month, whilst two were each of moderate (20%) and mild (20%) categories of COVID. The patients were managed with amphotericin-B along with surgical intervention. In this case series, 70% of all CAMA ( Rhizopus arrhizus with Aspergillus flavus in seven and Aspergillus fumigatus in three patients) patients survived, connoting the critical importance of a high index of clinical suspicion and accurate microbiological diagnosis for managing invasive molds. Conclusions Mixed fungal infections i.e. CAMA during COVID and post-COVID periods may be an emerging disease. This outbreak is seen particularly in such patients with uncontrolled diabetes, on steroids, or cocktail therapy, or living in unhygienic environments.We believe that our findings would help gain a better insight into the risk and progression of invasive fungal mixed infections among COVID patients and thus play a pivotal role in diagnosing, classifying, and implementing an effective management strategy for treating similar cases in the future.
