BACKGROUND: The effect of immunomodulatory therapy with tocilizumab for coronavirus disease 2019 (COVID-19) in real-life clinical practice remains controversial. METHODS: Single-center retrospective matched cohort analysis including 47 consecutive patients treated with intravenous tocilizumab for severe COVID-19 pneumonia ("TCZ group"), matched by age, comorbidities, time from symptoms onset and baseline SpO(2)/FiO(2) ratio with 47 patients receiving standard of care alone ("SoC group"). RESULTS: There were no significant differences between the TCZ and SoC groups in the rate of clinical improvement (hospital discharge and/or a decrease of >/=2 points on a six-point ordinal scale) by day 7 (51.1% [24/47] versus 48.9% [23/47]; P-value=1.000). No differences were observed at day 14 in terms of clinical improvement (72.3% versus 76.6%; P-value=0.791), all-cause mortality (10.6% versus 12.8%; P-value=1.000), and the composite of invasive mechanical ventilation and/or death (25.5% versus 23.4%; P-value=1.000) either. Patients in the TCZ group had a more rapid normalization of C-reactive protein levels. CONCLUSIONS: No apparent benefit was observed in patients with severe COVID-19 treated with tocilizumab as compared to a matched retrospective cohort.
