Background: Tocilizumab, an interleukin-6 (IL-6) antagonist, is being evaluated for the management of covid-19 pneumonia. The objective of this study was to assess the effectiveness of Tocilizumab in severe covid-19 pneumonia. Methods: This was a retrospective, observational, single centre study performed in 121 patients diagnosed with severe covid-19 pneumonia. 83 patients received standard of care treatment whereas 38 patients received tocilizumab along with standard of care. Tocilizumab was administered intravenously at 8mg/kg (upto a maximum of 800mg). The second dose of Tocilizumab was given 12 to 24 hours apart. The primary outcome measure was ICU related and hospital related mortality. The secondary outcome measures were change in clinical status of patients measured by WHO (World Health Organisation) 7 category ordinary scale, changes in interleukin-6 (IL-6) levels, secondary infections and duration of ICU stay. Results: Tocilizumab was administered between 3-27 days after the patient reported symptoms ( a median of 10.9 days ) and between the 1st to 3rd day of ICU admission (median of 2.1 days) . In Tocilizumab group, 16(42.1%) of 38 patients died in ICU whereas in standard of care group, 27(32.53%) of 83 patients died. The difference in clinical status assessed using WHO (World Health Organisation) 7 category ordinary scale at 28 days between Tocilizumab group and standard of care group was not statistically significant (odds ratio 1.35, 95% confidence interval 0.61 to 2.97, p = 0.44). Conclusion: Tocilizumab plus standard care was not superior to standard care alone in reducing mortality and improving clinical outcomes at day 28.
