Abstract

Introduction: The aim of the study was to determine the survival probability of critically ill patients with COVID-19 infection who needed mechanical ventilation and to determine the efficacy of Tocilizumab use.

Methodology: The study was designed as a retrospective analysis of consecutive patients older than 18 years, treated in an intensive care unit. The criteria for admission to the intensive care unit was severe respiratory failure requiring mechanical ventilation. All patients received corticosteroid therapy (methylprednisolone 1-2 mg/kg). Tocilizumab was used at a dose of 8 mg/kg in patients with a severe form of the disease (onset, or developed ARDS), followed by cytokine storm (IL-6 ≥ 40 ng/L and CRP ≥ 50 mg/L).

Results: 88 patients were included in the study. Intrahospital mortality was 48.86%. No statistically significant difference was observed between patients with and without tocilizumab therapy. In the group of patients in whom this therapy was applied, the values of intrahospital survival were 45.7%, while in the group without this therapy the probability of intrahospital survival was only 0.93%. The probability of survival in the group with noninvasive mechanical ventilation (NIV) was 94.7%, while in the group with invasive mechanical ventilation (IMV) 0.78%. The duration of symptoms before hospitalization (RR-1.088 CI 1.025-1.155, p < 0.05), as well as the duration of IMV (RR-0.906 CI 0.841-0.976, p < 0.05), were shown to be an independent predictor of poor outcome.

Conclusions: The mortality of patients with the most severe form of respiratory failure caused by COVID-19 infection remains high. Independent predictors of poor outcomes were needed for invasive mechanical ventilation and the duration of symptoms before hospitalization or late initiation of appropriate therapy.
