What progress has been made in treatment of immunocompromised COVID-19 patients?

While immunocompromised patients are at very high risk of developing severe COVID 19, few of them have been enrolled in studies aimed at evaluating treatments. In the early stages of research on this disease, glucocorticoid therapy became the standard of care for patients requiring oxygen supplementation. It has been demonstrated that the neutralizing monoclonal antibody combination of Casirivimab and Imdevimab reduced (by 28 days) mortality in COVID-19 patients admitted to hospital who were seronegative at baseline, but not in those who were seropositive. There is still a need to determine the place of available various antivirals (Molnupiravir or Nirmatrelvir plus Ritonavir) and passive immunotherapies (Sotrovimab…) as well as convalescent plasma therapy in immunocompromised settings.
