NCT04779359

Brief Summary

To investigate the predictive role of lymphocyte subsets and other laboratory measurements in adult patients with COVID-19.This was a single center, retrospective study that involved adult patients with confirmed diagnosis of COVID-19. Electronic medical records were reviewed. Data including age, sex, symptom from onset to hospital admission and laboratory findings at admission of hospitalized patients with confirmed COVID-19 were extracted and analyzed retrospectively.This study indicates that the levels of lymphocyte subsets (CD4+, and CD8+) are associated with disease progression and severity, along with prognosis in patients with COVID-19.

Outcome Measures

Primary Outcomes (1)

  • Correlation of CD4+ and CD8+ T cell absolute counts to disease outcomes

    The study endpoints were to demonstrate whether CD4+ and CD8+ T cell absolute counts are prognostic marker in determining disease outcomes (including ICU admission and/or mechanical ventilation and/or mortality); to explore whether lymphocyte subset measurements recover at hospital discharge or in convalescence; lymphocyte subset measurements between severe and non-severe groups, at admission. In addition, association between CD4+ and CD8+ T cell absolute counts with cytokine levels and other laboratory parameters (neutrophil counts, total lymphocyte counts, platelet counts, C-reactive protein levels) were also assessed.
