An outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2, initially in December 2019 at Wuhan, China, subsequently spread around the world. We describe a case series of COVID-19 patients treated at our academic medical center with focus on cytokine storm and potential therapeutic role of tocilizumab. A 59-year-old female admitted for shortness of breath (SOB), productive cough, fever, and nausea in the setting of COVID-19 pneumonia. Oxygen saturation was 81% necessitating supplemental oxygen. She was transferred to intensive care unit (ICU) for worsening hypoxia; intubated and received tocilizumab following which her oxygen requirements improved. A 52-year-old female admitted from an outside hospital with SOB, intubated for worsening hypoxia, in the setting of COVID-19 pneumonia. She received tocilizumab 400 mg intravenous for 2 doses on ICU admission, with clinical improvement. A 56-year-old female hospitalized with worsening SOB, fever, and cough for 8 days saturating 88% on room air in the setting of COVID-19 pneumonia. Worsening hypoxia necessitated high flow nasal cannula. She was transferred to the ICU where she received 2 doses of tocilizumab 400 mg intravenous. She did not require intubation and was transitioned to nasal cannula. A hyperinflammatory syndrome may cause a life-threatening acute respiratory distress syndrome in patients with COVID-19 pneumonia. Tocilizumab is the first marketed interleukin-6 blocking antibody, and through targeting interleukin-6 receptors likely has a role in treating cytokine storm. We noted clinical improvement of patients treated with tocilizumab.
