#SARS-CoV-2 infection #enhancement by #amphotericin B: implications for disease management

ABSTRACT Severe coronavirus disease 2019 (COVID-19) patients who require hospitalization are at high risk of invasive pulmonary mucormycosis . Amphotericin B (AmB), which is the first-line therapy for invasive pulmonary mucormycosis, has been shown to promote or inhibit replication of a spectrum of viruses. In this study, we first predicted that AmB and nystatin had strong interactions with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) proteins using in silico screening, indicative of drugs with potential therapeutic activity against this virus. Subsequently, we investigated the impact of AmB, nystatin, natamycin, fluconazole, and caspofungin on SARS-CoV-2 infection and replication in vitro. Results showed that AmB and nystatin actually increased SARS-CoV-2 replication in Vero E6, Calu-3, and Huh7 cells . At optimal concentrations, AmB and nystatin increase SARS-CoV-2 replication by up to 100- and 10-fold in Vero E6 and Calu-3 cells, respectively. The other antifungals t...

The first reported case of #candidemia caused by the novel #Candida tropicalis diploid sequence type 1515

Abstract Introduction :  Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections , due to the widespread use of indwelling medical devices , total parenteral nutrition , systemic corticosteroids , cytotoxic chemotherapy , and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality , and drug resistance issues on a global scale. Methodology :  We report a case of a 43-year-old man who was admitted to our hospital for further management of severe coronavirus disease 2019 (COVID-19) pneumonia . During his stay in the ward, he received systemic corticosteroids for a total duration of 32 days. A broad-spectrum antibiotic (piperacillin-tazobactam) was also given due to copious amounts of tracheostomy secretions . Results :  The patient’s fever recurred following an afebrile interval of 11 days...
