What researchers measure

Primary outcomes

  1. Overall survival (30-day mortality)

    To evaluate the effectiveness of convalescent plasma therapy COVID-19, to decrease mortality in hospitalized patients with COVID-19 and who present some risk factor for clinical deterioration.

    Time frame: 30 days

Secondary outcomes

  1. Median length of hospital stay

    To describe the median length of hospital stay in days

    Time frame: 30 days

  2. Change in clinical status

    To asses the changes of disease severity, according to the COVID-19 disease severity from the World Health Organization (WHO) Interim guidance.

    Time frame: 0, 3, 7 and 14 days

  3. Change in inflammatory marker: ferritin

    To measure changes in ferritin (μg/L) at 0, 7 and 14 days

    Time frame: 0, 7 and 14 days

  4. Change in inflammatory marker: D dimer

    To measure changes in D dimer (mg/L) at 0, 7 and 14 days

    Time frame: 0, 7 and 14 days

  5. Change in inflammatory marker: leukocytes

    To measure leukocytes (/mm3) changes at 0, 7 and 14 days

    Time frame: 0, 7 and 14 days

  6. Serum Antibody Titers

    To measure immunoglobulin G (IgG) SARS-CoV 2 titles

    Time frame: 0, 3 and 7 days

  7. Transfer to ICU

    To asses the frequency of patients admitted to ICU

    Time frame: 30 days

  8. Transfusion related events

    To asses the frequency of adverse events to convalescent plasma

    Time frame: 4 hours
