COVID-19 Associated Invasive Pulmonary Aspergillosis: Diagnostic and Therapeutic Challenges.

Aspergillus co-infection in patients with severe coronavirus disease 2019 (COVID-19) pneumonia, leading to acute respiratory distress syndrome, has recently been reported. To date, 38 cases have been reported, with other cases most likely undiagnosed mainly due to a lack of clinical awareness and diagnostic screening. Importantly, there is currently no agreed case definition of COVID-19 associated invasive pulmonary aspergillosis (CAPA) that could aid in the early detection of this co-infection. Additionally, with the global emergence of triazole resistance, we emphasize the importance of antifungal susceptibility testing in order to ensure appropriate antifungal therapy. Herein is a review of 38 published CAPA cases, which highlights the diagnostic and therapeutic challenges posed by this novel fungal co-infection.

Multi-triazole-resistant Aspergillus fumigatus and SARS-CoV-2 co-infection: A lethal combination.

We report a case of severe COVID-19 pneumonia complicated by fatal co-infection with a multi-triazole resistant Aspergillus fumigatus and highlight the importance of recognising the significance of Aspergillus sp. isolation from respiratory samples. Early diagnosis and detection of triazole resistance are essential for appropriate antifungal therapy to improve outcome in patients with coronavirus associated invasive aspergillosis.
