Severe COVID-19 in Patients experiencing Cytokine Storm: Positive Outcomes (faster respiratory recovery, a lower likelihood of mechanical ventilation, and fewer in-hospital deaths) of high dose methylprednisolone plus tocilizumab (Actemra, Genentech) vs Supportive Care Alone

Reporter: Aviva Lev-Ari, PhD, RN

“COVID-19-associated cytokine storm syndrome [CSS] is an important complication of severe acute respiratory syndrome coronavirus-2 infection in up to 25% of the patients,” lead author Sofia Ramiro, MD, PhD, told Medscape Medical News.

The researchers assessed outcomes of 86 individuals with COVID-19-associated CSS treated with high-dose methylprednisolone plus/minus tocilizumab, an anti-interleukin-6 receptor monoclonal antibody. They compared them with another 86 patients with COVID-19 treated with supportive care before initiation of the combination therapy protocol.

Participants with CSS had an oxygen saturation of 94% or lower at rest or tachypnea exceeding 30 breaths per minute.

They also had at least two of the following:

• C-reactive protein > 100 mg/L;
• serum ferritin > 900 μg/L at one occasion or
• a twofold increase at admission within 48 hours; or
• D-dimer levels > 1500 μg/L.
