Evaluation of infliximab/tocilizumab versus tocilizumab among COVID-19 patients with cytokine storm syndrome

Coronavirus Disease 2019 (COVID-19) continues to spread rapidly. Monoclonal antibodies as well as anti-tumor necrosis factor are considered promising treatments for COVID-19. A prospective cohort study in which patients are divided into three groups. Group 1: moderate and severe COVID-19 patients received standard treatment; Group 2: moderate and severe COVID-19 patients received tocilizumab; Group 3: moderate and severe COVID-19 patients received treatment with infliximab and tocilizumab. 153 patients were recruited in the study. 40 received standard treatment alone, 70 received tocilizumab with standard treatment, and 43 received tocilizumab/infliximab with standard treatment. There was a significant difference in length of hospital stay (10.3, 8.9, and 7.6 days respectively P = 0.03), need for a non-invasive mechanical ventilator (4, 5, and one patient; P = 1.2E−8), intensive care admission (32, 45, and 16 patients; P = 2.5E−5), the occurrence of sepsis (18, 12, and 10 patients; P = 0.005) and in death (42.5%, 14.2%, and 7%; P = 0.0008) which were significantly lower in tocilizumab/infliximab group compared to tocilizumab and standard of care groups. Our study showed that tocilizumab/ infliximab in addition to standard of care was considered a promising treatment for moderate and severe COVID-19 patients.
