RESUMEN
INTRODUCTION: Venous thromboembolism (VTE) and arterial thrombotic (AT) events are a striking feature of severe COVID-19, however, relationship of remdesivir use and the risk of thrombotic events is unknown and has not been investigated before. METHODS: We retrospectively analyzed a cohort of 876 consecutive hospitalized severe and critical COVID-19 patients who were treated with remdesivir and compared them to 876 case-matched control patients. All patients were treated in our tertiary-level institution in period from 10/2020 to 6/2021. VTE and AT were diagnosed by objective imaging and laboratory methods. RESULTS: After exclusion of 71 VTE and 37 AT events present at the time of hospital admission, there were a total of 70 VTE (35 in the remdesivir and 35 in the control group) and 38 AT events occurring during hospitalization (13 in the remdesivir and 25 in the control group). There was a similar cumulative post-admission VTE incidence among both remdesivir and matched control patients (P = 0.287). Significantly lower cumulative post-admission AT incidence was observed among patients treated with remdesivir than among matched control patients (1.7% vs 3.3%, HR = 0.51, P = 0.035). Tendency for lower AT rates was evident in subgroups of patients stratified according to the type of AT, as well as according to the intensity of required oxygen supplementation at the time of remdesivir use. CONCLUSION: Remdesivir use in severe and critical COVID-19 patients might be associated with lower occurrence of AT during hospitalization, whereas similar rates of VTE events were observed among both patients treated with remdesivir and control patients.

Early Career Members of Assembly 2 (Respiratory Intensive Care) attended the 2022 European Respiratory Society (ERS) International Congress in Barcelona, Spain. The conference covered acute and chronic respiratory failure. Sessions of interest to our Assembly members and to those interested in respiratory critical care included the state-of-the-art session on respiratory critical care, the journal session (ERS/Lancet) on acute respiratory distress syndrome (ARDS) phenotyping into precision medicine, and sessions on specificity of coronavirus disease 2019 ARDS and its post-critical care. A symposium on treatment of acute respiratory failure in patients with COPD and innovations in mechanical ventilation either in the intensive care unit or at home were also reported upon. These sessions are summarised in this article.
RESUMEN
INTRODUCTION: The impact of asthma and chronic obstructive pulmonary disease (COPD) in the setting of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection is not clearly defined. Blood eosinophil count is a standard diagnostic test which, according to the previously published literature, might have a potential prognostic role on mortality in patients with SARS-CoV2 infection. AIM: To investigate the potential prognostic value of peripheral blood eosinophil count on all-cause mortality of patients hospitalized with SARS-CoV2 infection, as well as to assess the impact of asthma or COPD premorbidity on all-cause mortality. MATERIAL AND METHODS: We conducted a retrospective registry-based cohort study. Survival analysis was performed by employing the Cox proportional hazards regression model at 30 days of follow-up. Prognostic value of eosinophil count on all-cause mortality was assessed using receiver-operating characteristic (ROC) curve analysis. RESULTS: A total of 5653 participants were included in the study. Our model did not reveal that pre-existing asthma or COPD is a statistically significant covariate for all-cause mortality but, indicated that higher eosinophil count at admission might have a protective effect (hazard ratio, HR 0.13 (95% confidence interval, CI 0.06-0.27), pâ¯= 0.0001). ROC curve analysis indicates cut-off value of 20 cells/mm3 (81% specificity; 30.9% sensitivity). CONCLUSION: Our results indicate that eosinophil count at hospital admission might have a potential prognostic role for all-cause mortality at 30 days of follow-up; however this was not demonstrated for pre-existing obstructive lung diseases.
