Similarly, in Brazil, Riche et al. [82] observed a 10-fold increase in candidemia amongst a cohort of critically ill COVID-19 patients receiving high doses of corticosteroids such as prednisone, hydrocortisone, methylprednisolone and dexamethasone, while a retrospective study conducted in Chicago and involving 111 COVID-19 patients receiving tocilizumab (a monoclonal antibody that inhibits binding of IL-6 to the membrane and soluble receptors [102]) was significantly linked with the risk of developing fungal pneumonia and sinusitis [103]. The gene discussed is IL6; the disease is COVID-19.
