Early High-Titer #Plasma Therapy to Prevent Severe #Covid-19 in Older Adults

Therapies to interrupt the progression of early coronavirus disease 2019 (Covid-19) remain elusive. Among them, convalescent plasma administered to hospitalized patients has been unsuccessful, perhaps because antibodies should be administered earlier in the course of illness. We conducted a randomized, double-blind, placebo-controlled trial of convalescent plasma with high IgG titers against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in older adult patients within 72 hours … Continue reading Early High-Titer #Plasma Therapy to Prevent Severe #Covid-19 in Older Adults

Sex, age, and hospitalization drive #antibody responses in a #COVID-19 convalescent plasma donor population

Convalescent plasma is a leading treatment for coronavirus disease 2019 (COVID-19), but there is a paucity of data identifying its therapeutic efficacy. Among 126 potential convalescent plasma donors, the humoral immune response was evaluated using a severe acute respiratory syndrome coronavirus 2 (SARS–CoV-2) virus neutralization assay with Vero-E6-TMPRSS2 cells; a commercial IgG and IgA ELISA to detect the spike (S) protein S1 domain (EUROIMMUN); IgA, … Continue reading Sex, age, and hospitalization drive #antibody responses in a #COVID-19 convalescent plasma donor population

Early experience with convalescent #plasma as immunotherapy for #COVID‐19 in China: Knowns and unknowns

In the absence of a vaccine or specific drug treatment options for coronavirus disease (COVID‐19), attention has been shifted in China to the possible therapeutic use of convalescent plasma. COVID‐19 convalescent plasma (CCP) is currently under investigation. We summarized clinical studies and other research data available as of 5 May 2020 on CCP therapy according to the Clinical Treatment Guideline of COVID‐19 Convalescent Plasma in … Continue reading Early experience with convalescent #plasma as immunotherapy for #COVID‐19 in China: Knowns and unknowns
