Etoposide as Salvage Therapy for Cytokine Storm due to COVID-19.

COVID-19 has resulted in significant morbidity and mortality due to lack of effective therapies. Therapeutic strategies under investigation target the overactive cytokine response with anti-cytokine or immunomodulators therapies. We present a unique case of severe cytokine storm resistant to multiple anti-cytokine therapies, but eventually responsive to Etoposide. Thus, Etoposide may have a role as salvage therapy in treatment of cytokine storm in COVID-19. To our knowledge, this is the first reported case of use of Etoposide in COVID-19.
