Effect of Tocilizumab on Intensive Care Patients With COVID-19 Pneumonia, a Retrospective Cohort Study
Effect of Tocilizumab on Intensive Care Patients With COVID-19 Pneumonia, a Retrospective Cohort Study
Although its safety and efficacy in the COVID-19 patient population are still unclear, tocilizumab is one of treatment. Tocilizumab is a U.S. Food and Drug Administration approved IL-6 receptor antagonist widely used to treat CRS secondary to the chimeric antigen receptor T cell. In this study the investigators will evaluate the efficacy of Tocilizumab, an IL-6 antagonist administered in the early period in intensive care patients with COVID-19 pneumonia followed by hypoxic and systemic inflammation is predominant, but who do not support mechanical ventilation.
With this study, the investigators will evaluate the efficacy of Tocilizumab, an IL-6 antagonist administered in the early period in intensive care patients with COVID-19 pneumonia followed by hypoxic and systemic inflammation is predominant, but who do not support mechanical ventilation.
With this study, those with signs of hypoxia and systemic inflammation followed by COVID-19 pneumonia (SpO2 <90% on room air together with the elevation of any two of the systemic inflammatory markers such as CRP, LDH and Ferritin) and / or acute bilateral infiltrates on chest radiograph and tocilizumab the patients who received treatment and those who received standard therapy will be compared.
In the study, cases followed up with COVID-19 pneumonia and respiratory failure between March 2020 and March 2021 will be retrospectively evaluated. Tocilizumab was applied as 400 mg - 800 mg iv (depending on weight). A second dose could be given 12-24 h later if the patient's condition had not improved. Primary end point was determined as intensive care mortality.
