NCT02644798

Brief Summary

Acute respiratory distress syndrome (ARDS) is characterized by increased pulmonary vascular permeability and reduced aerated lung tissue. With an extremely high hospital mortality among 35 - 46%, current therapeutic strategies to increase ARDS survival are still limited. Advances in etiology and pathology of ARDS are urging. Numerous genetic variants were identified associated with ARDS outcome. By whole-exome sequencing association study, our goal was to explore the associations between genetic variants and ARDS outcome.

  • Number of survived participants

    Survivors and non-survivors in ICU

    through study completion, an average of 28 day

Study Arms (1)

ARDS patients

Adult ARDS (according to Berlin definition) patients were enrolled in the trial. The diagnostic criteria included (a) within one week of a known clinical insult or new or worsening respiratory symptoms; (b) chest imaging showing that bilateral opacities-not fully explained by effusions, lobar/lung collapse, or nodules; (c) respiratory failure not fully explained by cardiac failure or fluid overload; and (d) arterial partial pressure of oxygen / fraction of inspiration oxygen (PaO2/FiO2 ratio, P/F ratio) less than or equal to 300 mmHg.

Other: Baseline-recorded data recorded

Interventions

Baseline-recorded data recorded. Peripheral blood samples were drawn.
