Convalescent plasma therapy has been implemented in a few cases of severe coronavirus disease 2019.No report about convalescent plasma therapy in treating patients with prolonged positivity of SARS-CoV-2 RNA has been published.In this study,we conducted a retrospective observational study in 27 patients with prolonged positivity of SARS-CoV-2 RNA,the clinical benefit of convalescent plasma therapy were analyzed.qRT-PCR test of SARS-CoV-2 RNA turned negative(≤ 7 days)in a part of patients(early negative group,n = 15)after therapy,others(late negative group,n = 12)turned negative in more than 7 days.Pulmonary imaging improvement was confirmed in 7 patients in early negative group and 8 in late negative group after CP therapy.Viral load decreased in early negative group compared with late negative group at day 3,5,7 after implementing convalescent plasma therapy.Patients in early negative group had a shorter median length of hospital stay.In conclusion,convalescent plasma therapy might help eliminate virus and shorten length of hospital stay in patients with prolonged positivity of SARS-CoV-2 RNA.
