Convalescent plasma doesn't cut death, hospital stays in COVID patientsA study late last week found that convalescent plasma (CP) treatment did not significantly reduce mortality, but improved hospital discharge rates for patients 65 and older.
The study in Clinical Infectious Diseases is one of the first to analyze clinical outcomes for closely matched cohorts of CP and control patients.
In convalescent plasma treatment, plasma collected from individuals who have recovered from an infection is transfused into currently infected patients to provide passive immunity.
CP treatment has a long history of application for other types of infections and is in clinical use to treat COVID-19 patients.
