BACKGROUND: We sought to evaluate the effect of tocilizumab (TCB), a recombinant humanized monoclonal antibody against soluble interleukin-6 receptors, in patients hospitalized for coronavirus disease 2019 (COVID-19). METHODS: We included all patients with laboratory-confirmed COVID-19 who had completed hospitalization between March 10, 2020 and April 10, 2020 with follow-up through April 20, 2020. Patients who received TCB in addition to standard of care within 48 h of admission were matched in a 1:2 fashion to a similar cohort who received standard of care alone. Clinical outcomes were compared between matched groups. The primary outcome was de-escalation in oxygen therapy. Secondary outcomes were in-hospital death, septic shock, and acute kidney injury (AKI) requiring hemodialysis. RESULTS: Out of 77 patients who received TCB in addition to standard of care, 34% (n = 26) received TCB within 48 h of admission. One-to-two propensity matching identified 20 versus 40 patients in the TCB and no-TCB treatment arms. In the TCB group, an improvement in oxygenation was observed in 80% (n = 16) of the patients by 7 days post TCB administration. After matching, there was no difference in clinical outcomes between TCB and no-TCB patients. In-hospital death: 10% versus 8%; p = .823, septic shock: 10% versus 11%, p = .912, AKI requiring hemodialysis (10% vs. 13%; p = .734). CONCLUSIONS: Early treatment with TCB in patients admitted for COVID-19 led to an improvement in their oxygen status during hospitalization. This change however did not translate into improved survival when compared to a matched cohort with a similar clinical profile.
