Blood Interferon-alpha Levels and Severity, Outcomes, and Inflammatory Profiles in Hospitalized COVID-19 Patients |pdf=|usr=}}{{33767713}} gab.com Text Blood Interferon-alpha Levels and Severity, Outcomes, and Inflammatory Profiles in Hospitalized COVID-19 Patients JO: Front Immunol http://www.kidney.de/pget.php?&tw=1&pmid=33767713 #FOAvip Background: Deficient interferon responses have been proposed as one of the relevant mechanisms prompting severe manifestations of COVID-19. Objective: To evaluate the interferon (IFN)-alpha levels in a cohort of COVID-19 patients in relation to severity, evolution of the clinical manifestations and immune/inflammatory profile. Methods: This is prospective study recruiting consecutive hospitalized patients with respiratory failure associated with SARS-COV-2 infection and matched controls. After enrollment, patients were assessed every 7 +/- 2 days for additional 2 consecutive visits, for a total of 21 days. The severity of the clinical condition was ranked based on the level of respiratory support required. At each time-point blood samples were obtained to assess immune cells and mediators by multiplex immunoassay. Results: Fifty-four COVD-19 and 11 control patients matched for severity were enrolled. At recruitment, lower levels of blood IFN-alpha were found in COVID-19 patients compared to controls (3.8-fold difference, p < 0.01). Improvements in COVID-19 severity were paralleled by a significant increase of blood IFN-alpha levels. A significant increase in blood IFN-alpha was found over the study period in survivors (70% of the study population). A similar trend was found for blood IFN-beta with IFN-beta levels below the threshold of detectability in a substantial proportion of subjects. Significantly higher values of blood lymphocytes and lower levels of IL-10 were found at each time point in patients who survived compared to patients who died. In patients who clinically improved and survived during the study, we found an inverse association between IL-10 and IFN-alpha levels. Conclusion: The study identifies a blood immune profile defined by deficient IFN-alpha levels associated with increased IL-10 expression in patients progressing to severe/life threatening COVID-19 conditions, suggesting the involvement of immunological pathways that could be target of pharmacological intervention. Clinical Trial Registration: ClinicalTrials.gov identifier NCT04343053.
