Therapeutic plasma exchange in a critically ill Covid‐19 patient
Archive ouverte
International audience. Here we describe the effect of therapeutic plasma exchange with 5% albumin as sole replacement solution for the management of Covid-19. A 74-year-old man was admitted for severe Covid-19 acute respiratory distress syndrome. Based on the growing body of evidence that cytokine release syndrome, and especially interleukin-6, plays a key role in critically ill Covid-19 patients, we decided to implement therapeutic plasma exchange as a rescue therapy. The patient's clinical status rapidly improved, and biological records showed convincing results of decrease in interleukin-6 and inflammatory parameters under treatment. This case presents a proof-of-concept for the use of therapeutic plasma exchange with 5% albumin as sole replacement solution in a critically ill Covid-19 patient with cytokine release syndrome. This could constitute a major benefit in terms of security compared to long-lasting immunosuppressive monoclonal antibodies, or to therapeutic plasma exchange with plasma as replacement fluid. Hence, we think that a further evaluation of risk-benefit balance of this therapy in severe cases of Covid-19 should rapidly be undertaken.
