Insights

Convalescent plasma transfusion (CPT) shows promise for treating COVID-19. This therapy improved patient outcomes, reduced mortality, and demonstrated a low frequency of adverse events in severe and critical cases.

Area of Science:

  • Infectious Diseases
  • Immunology
  • Critical Care Medicine

Background:

  • No specific antiviral medication or vaccine exists for COVID-19.
  • Treatment primarily relies on supportive care measures.
  • Convalescent plasma transfusion (CPT) is being investigated as a potential therapy.

Purpose of the Study:

  • To evaluate the efficacy and safety of CPT in patients with COVID-19.
  • To review existing literature on CPT for COVID-19, SARS, and MERS.

Main Methods:

  • A literature search was conducted on PubMed for studies involving convalescent plasma and COVID-19, SARS, or MERS.
  • 13 studies on CPT in severe and critical COVID-19 patients were identified and analyzed.

Main Results:

  • CPT demonstrated clinical improvement, enhanced ventilatory patterns, and resolution of lung injuries in COVID-19 patients.
  • Treatment led to decreased mortality, improved laboratory parameters, increased neutralizing antibodies, and reduced viral load.
  • Adverse events associated with CPT were infrequent.

Conclusions:

  • CPT is a potentially beneficial therapy for severe and critical COVID-19.
  • Despite methodological limitations in current studies, CPT shows a favorable safety profile and clinical efficacy.
