RESUMEN
BACKGROUND/AIM: Immunomodulatory therapy with Tocilizumab (TCZ), a monoclonal antibody against interleukin-6 receptor-alpha, has been endorsed by the World Health Organization and other major regulatory bodies, as part of the standard-of-care therapy for severe or critical COVID-19 cases despite discordant trial outcomes. The aim of the present study was to report the experience of our center regarding TCZ routine use in severely ill COVID-19 patients who were hospitalized during the third pandemic wave in Greece. PATIENTS AND METHODS: From March 2021 to December 2021, we retrospectively analyzed COVID-19 patients with radiological findings of pneumonia and signs of rapid respiratory deterioration that were treated with TCZ. The primary outcome included the risk of intubation or/and death in TCZ-treated patients compared to matched controls. RESULTS: TCZ administration was neither predictive of intubation and/or death [OR=17.5 (95% CI=0.47-652.2; p=0.12)] or associated with fewer events (p=0.92) in multivariate analysis. CONCLUSION: Our single-center real-life experience is in line with recently published research, revealing no benefit from TCZ routine use in severely or critically ill patients with COVID-19.

In several randomized studies, remdesivir (RDV) has been reported to shorten the recovery period and improve clinical outcomes in COVID-19 patients, and thus, it is recommended as a standard of care. Nevertheless, controversial reports have been published. The aim of the present study is to evaluate the effectiveness of remdesivir in hospitalized patients with COVID-19 pneumonia at three Greek University Departments of Infectious Diseases with homogenous treatment protocols. From September 2020 to February 2021, we retrospectively analyzed adults hospitalized with confirmed SARS-CoV-2 infection and radiological findings of pneumonia, who received remdesivir once daily for five days. Exploratory end points were duration of hospitalization, time of intubation, and death. Overall, 551 patients were included in the study. The optimal cutoff point for the number of days needed after symptom initiation for drug administration associated with better clinical outcome was 7 days. Higher odds for discharge and lower for intubation were observed in patients with treatment initiation ≤7 days (p = 0.052 and p = 0.019, retrospectively) regardless of gender (p = 0.537), hypertension (p = 0.096), dyslipidemia (p = 0.221), diabetes mellitus (p = 0.306), and usage of immunomodulators (p = 0.408). Our study has demonstrated beneficial effects of early treatment with remdesivir (≤7 days from symptom onset) on rates of intubation and probability of discharge.
