Effectiveness of Tocilizumab in a COVID-19 Patient with Cytokine Release Syndrome
KeywordsTocilizumab, COVID-19, cytokine release syndrome
Cytokine release syndrome (CRS) is a systemic inflammatory response that can be triggered by many factors such as infections. CRS in patients with coronavirus disease 2019 (COVID-19) is life-threatening and can occur very rapidly after COVID-19 diagnosis. Tocilizumab (TCZ), an interleukin?6 (IL-6) inhibitor, may ameliorate the CRS associated with severe COVID?19 and thus improve clinical outcomes. We present a case of life-threatening CRS caused by COVID-19 infection successfully treated with TCZ.
