This is a multicenter open-label randomized study for the early treatment of pneumonia due to SARS-COV2 with transfusion of convalescent plasma.

Patients with pneumonia due to SARS-CoV-2 will be randomized to receive or not convalescent plasma collected by recovered patients with previous diagnosis of COVID19

This is a multicenter open-label randomized study for the early treatment of pneumonia due to SARS-COV2 with transfusion of convalescent plasma.

Patients with SARS-CoV2 pneumonia not requiring mechanical ventilation (both non invasive and invasive) will be randomized to receive or not convalescent plasma.

Patients in the plasma group will receive 200-300 ml of plasma collected by recovered patients with previous diagnosis of COVID19, plus standard therapy; Patients in the control group will receive the standard therapy. A rescue therapy will be allowed in case of clinical worsening.

Patients will be followed until day n30 from randomization.

Inclusion Criteria:

  • Suggestive radiological imaging (CT, RX, ultrasound);
  • Respiratory failure not fully explained by heart failure or fluid overload;
  • PaO2/FiO2 200-350 mmHg;
  • Signed informed consent

Exclusion Criteria:

• need of non invasive or invasive mechanical ventilation at the time of randomization;
• PaO2/FiO2 <200;
• patients with hypersensitivity or allergic reaction to blood products or immunoglobulins;
• patients who expressly refuse to adhere the clinical study;
• use of IL-6 Receptor inhibitors, IL-1 inhibitors, JAK inhibitors, TNF inhibitors;
