Background: Remdesivir (REM) has shown potent antiviral activity in vitro and efficacy in animal models of COVID-19; nevertheless, clinical trials and real-life reports have shown conflicting data on its effectiveness. Aims of the study were to evaluate the impact of remdesivir on I) Intensive Care Unit (ICU) admission, II) need for orotracheal intubation (OTI) and III) in-hospital mortality. Furthermore, we estimated the kinetics of laboratory parameters and assessed the risk factors for in-hospital mortality in the remdesivir population.
Methods: We conducted a retrospective, single-center, case-control (1:1) study including hospitalized patients with confirmed SARS-CoV-2 infection. Cases were patients treated with remdesivir for 5 days, controls were patients not receiving remdesivir.
Results: A total of 192 patients (96 cases and 96 controls) were included in the study. Patients receiving remdesivir had a lower rate of ICU admission and need for OTI than controls, whereas no difference between cases and controls were observed as for mortality rate. However, at multivariable analysis remdesivir was not associated with ICU admission neither with OTI. Instead, presence of haematological malignancies, lower duration of symptoms, higher severity of infection and low lymphocytes count at admission were independently associated with in-hospital mortality. In patients treated with remdesivir a low albumin value and duration of lymphopenia were significantly associated with mortality.
Conclusions: Our real-life study showed that therapy with remdesivir did not have impact on either ICU admission, need for OTI or in-hospital mortality.
