Study summary

The present multicenter prospective observational study aims to assess the long-term effects of COVID-19 on patients with Acute Respiratory Distress Syndrome (ARDS).

This is a hybrid design study with components of cohort and case-control designs. Survivors of hospitalization due to ARDS caused by SARS-CoV-2, survivors of hospitalization due to ARDS caused by other etiologies not associated with SARS-CoV-2, and family controls without history of COVID-19 or hospitalization will be followed up for a period of 6 months.

What researchers measure

Primary outcomes

  1. Diffusion capacity for carbon monoxide

    Proportion of participants with diffusion capacity for carbon monoxide \< 80% of predicted

    Time frame: The outcome will be assessed 6 months after enrollment

Secondary outcomes

  1. Physical functional status

    Physical functional status as assessed by the modified Barthel index (score ranges from 0 to 100; higher scores indicate less functional dependence)

    Time frame: The outcome will be assessed at 3 and 6 months after enrollment

  2. Instrumental Activities of Daily Living

    The outcome will be assessed using the Lawton \& Brody Instrumental Activities of Daily Living Scale (the score ranges from 0 to 8, with higher scores indicating less dependence)

    Time frame: The outcome will be assessed at 3 and 6 months after enrollment

  3. Muscular function and strength

    Muscular function and strength as assessed by Strength, assistance with walking, rising from a chair, climbing stairs, and falls (SARC-F) questionnaire. Scale scores range from 0 (best) to 10 (worst)

    Time frame: The outcome will be assessed at 3 and 6 months after enrollment

  4. Score of dyspnea

    The outcome will be assessed using the modified medical research council dyspnea scale. Scores ranges from 0 to 4, with higher scores indicating worse symptoms.

    Time frame: The outcome will be assessed at 3 and 6 months after enrollment

  5. Utility score of health related quality of life

    The outcome will be assessed using the Brazilian version of the Euroqol-5D-3L (EQ-5D3L) questionnaire. The utility score derived from the EQ5D-3L ranges from 0 (death) to 1 (perfect health).

    Time frame: The outcome will be assessed at 3 and 6 months after enrollment

  6. Radiologic patterns of intersticial lung disease

    Radiologic patterns of intersticial lung disease as assessed by high resolution computed tomography chest scan.

    Time frame: The outcome will be assessed at 6 months after enrollment

  7. Radiologic patterns of myocarditis sequalae

    Radiologic patterns of myocarditis sequalae as assessed by cardiac magnetic resonance imaging

    Time frame: The outcome will be assessed at 6 months after enrollment

  8. Radiologic patterns of sarcopenia

    Radiologic patterns of sarcopenia as assessed by high resolution computed tomography chest scan.

    Time frame: The outcome will be assessed at 6 months after enrollment

  9. Incidence of major cardiovascular events

    Incidence of major cardiovascular events (composite endpoint of non-fatal stroke, non-fatal acute myocardial infarction, or cardiovascular death)

    Time frame: The outcome will be assessed at 3 and 6 months after enrollment

  10. Incidence of thromboembolic events
